The Research and Development of FLS-480 Plastic Injection Machine’s Demoulding Installation

0 Quotations

FLS-480 plastic injection machine is a kind of machine which can be used for breaking point injection and local injection injection of collecting cable in seismic prospecting. The principle is the use of plastic raw materials by heating thermoplastics into special shape plastic products wrapped cable, it is mainly suitable for 428XL cable and G3i cable repair injection molding. However, after the injection molding is completed, the injection mold is closely combined with the molding process after injection molding, and it cannot be separated directly by manpower. Therefore, we need a labor-saving, convenient and fast device to separate the acquisition cable after injection molding from the injection mold, that is, demoulding.

1 The need for the development of a defilming device

It is found that the repaired cable needs to be demoulded after injection molding, and the demoulding device is the key. That is to say, the original method of our unit is to use a bench vise to do this work, but it is difficult to operate it. The use of bench vice demoulding times more, the back of the transmission screw wear strict heavy, screw and screw slip, need to continue to replace the transmission screw and nut repair can continue to work, greatly affecting the cable maintenance speed. Therefore, it is necessary to study and discuss the current demoulding device, and to develop a new demoulding device for seismic acquisition cable, which is labor-saving, durable, high safety and can achieve rapid maintenance.

The manufacture idea and basic principle of the defilm device

The so-called demoulding is to borrow external forces to separate the plastic molding mold used by the FLS-480 injection molding machine from the thermoplastic and the special shaped plastic products wrapped around the outside of the cable to achieve the purpose of the cable can be restored to good use.

2. How to fix the injection part and the mold? How to reset after separation?

What about the safety factor is the first thing we have to consider [2] Therefore, the drive part is the main core of the mold power, and the power of the drive equipment directly affects the performance of the mold equipment and the working state, and also affects the quality and progress of the demoulding work. At present, the commonly used types of power drive are hydraulic drive, pneumatic drive and electric drive.

The analysis revealed that:

(1) Air pressure drive dynamic safety to be higher, but the purchase of air pressure container equipment, high cost, the air pressure device is not familiar with the safety of hidden dangers, not easy to operate.

(2) The electric drive is more complex than the actual, high cost, and need to set up a special circuit. Need to have a certain degree of electrical expertise to participate in the operation to achieve.

(3) The hydraulic pressure drive is simple, the dynamic force is large and small, and the operation is convenient. It is easy to separate the molded part from the mold simply by finding the right hydraulic drive.

It can be seen that a good and suitable power drive equipment plays a pivotal role in the completion of the use effect of the demoulding device. After multi-party comparison, the final selection of common oil hydraulic jack as the driving part of the power source, the production of stripping device is more appropriate.

2. the basic principle of hydraulic jacks, also known as hydraulic jacks, mainly using plunger

Or hydraulic cylinder as a rigid top lift, and hydraulic jack has a very good lifting mechanism, so it is used for lifting heavy objects to save energy, and the hydraulic pressure is simple. Light weight, easy to use features, the cable this road demoulding to hydraulic jacks driven equipment will be injection parts and mold separate to complete the demoulding task is completely up to.

The manufacturing process of this mold release device

3. The design power drive part of the demoulding installation: according to the need to separate the injection part from the mold

The size of the force, power drive equipment to choose a 3.2T oil pressure thousand jin top. Fixed part of the power source: Measure the size of the hydraulic jack, and design the base in a vertical working state. Fixed and separated parts of injection molding parts and molds: Design fixed clamping position and moving clamping position of fixed injection molding parts. Positioning device part: designed to separate the injection parts from the mold after the movable clamping position, so that the next rapid demoulding. This road demoulding design is shown in Figure 1 and Figure 2.

3. 2 the preparation of the material for this road is shown in table 1:

3.3 The production of this road demoulding device

Power driven part: find a piece of steel cut to size 155mm × 250mm as the base, the hydraulic jack fixed in the

Thereon, as shown in FIG. 3.

Cut 45 U groove steel with an inch of 360 mm, and cut 15 mm x 25 mm on one side of the cut groove steel to install the movable card and weld it on the side of base.

Separation device part: The steel plate is cut out with a moving clip of 90mm × 60mm and an opening of 30mm × 40mm is cut on the moving clip. Steel plate cut 120 m m x 60 m m fixed card, and made into L shape used as a fixed clip, the same cut 30 m x 40 m m on the fixed clip The hole is fixed on the groove steel standing vertically on the bottom seat, as shown in Figure 4.

The slider homing device part: the steel bar is cut into 2 sections with a size of 334mm, the hollow steel pipe of DN20 is cut into two sections with a size of 50mm in advance, and it is welded between the bottom and the top part of the channel steel bar. The spring is produced by electric welding on the steel bar and the hollow steel pipe respectively.

Of the hanging contact, put the spring as shown in Figure 5.

4 Functional verification of this demoulding device

The demoulding process is carried out with the demoulding device, and the demoulding work can be easily completed after testing and testing. And in the cable injection molding machine in the production of this way for stripping. Through the comparison of demoulding data, it is found that a single bench vise is damaged after an average of 501 times, and the work energy of the developed device is normal after 1133 times of demoulding, and can be continued to be used.

Close the software after the end, turn off the SVM power supply; (3) The mouse, keyboard and display device are connected to the RIC and powered on

Machine. RIC will be the beginning of the line, after finishing into the Linux system, this time pop-up “system settings” dialog box, click on the cancel (Cancel), the new text on the table folder “scripts”;

(4) copy the Inova-ric-startup.pl file to the “scripts” folder, and change the permission of the file’s Properties to Anyone. Transport Inova-ric-

Startup.pl file, select Execute In Ter-minal, hold USB stick in state until RIC auto-restart;

(5) Restore the internal connection of the SVM, connect the USB connection and network cable to the RIC, and the Raveon station is connected to a GPS antenna and a UHF antenna. After rebooting, RIC will upgrade to the latest version of the software, read the configuration of the Raveon station and set the WiFi name to be the same as the station;

(6) RIC mirror image recovery finished, can use the RCU software on the Raveon station configuration, and connect the navigation and Vibpro HD box body

For testing.

4 Conclusion

With the successful application of Hypersource in domestic exploration projects and large exploration projects in the Middle East, more and more people are aware of its convenience and flexibility. Because of its complex structure, SVM will have various problems in the production process. Therefore, it is required that the operator should not only master how to operate in the application process, but also learn how to determine the fault location and repair it in time. This can not only effectively improve the repair rate of equipment, ensure production efficiency, but also help to improve the maintenance and use of personal seismic equipment.
