Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine clamps, in particular to a feeding clamp for injection molding of metal parts. Background Art

[0002] The metal insert injection molding process mainly places the metal insert as an injection molding insert in the mold in advance, and then injects plastic into the mold and solidifies and cools it, so that the metal insert and the plastic form a whole to obtain a metal insert injection molding product. Injection molding is a method for producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding and die casting. In the current injection molding machine, it is often necessary to use a clamping device to clamp the material during the production process.

[0003] The prior art discloses an injection molding robot clamp with application number CN202222062040.1, which drives the gear to rotate through a driving component, thereby driving the connecting part to rotate, thereby adjusting the position of the clamping component and clamping the material.

[0004] However, the above technical solution lacks adjustment of the clamping range during use and can only clamp materials within a limited range. It also lacks adjustment for metal injection molded parts. Metal injection molded parts are produced at high temperatures and parts may still be soft. Therefore, hard metal reinforcement may affect the surface of metal injection molded parts. Utility Model Content

[0005] In order to solve the deficiencies mentioned in the above background technology, the purpose of the utility model is to provide a loading fixture for injection molding of metal parts.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A movable sliding groove is provided at the top of the telescopic bracket, and a connecting fixing plate is fixedly connected to one end of the telescopic bracket close to the clamping plate;

[0009] The bottom end of the telescopic bracket is fixedly connected to a loading clamping plate;

[0010] The bottom end of the loading clamping plate is fixedly connected with a movable slide, and the bottom end of the movable slide is fixedly connected with a clamping plate connecting plate.

[0011] Furthermore, movable brackets are rotatably connected to both sides of the bottom end of the clamp bracket, the bottom end of the movable bracket is rotatably connected to a movable connecting frame, a movable hole is opened at the top end of the clamp bracket, and a control cylinder is fixedly connected to the top end of the clamp bracket.

[0012] Furthermore, the control bracket is fixedly connected to the output end of the control cylinder, the bottom end of the control bracket is fixedly connected to a telescopic movable support rod, and the telescopic movable support rod passes through the movable hole and is fixedly connected to a support rod connecting frame.

[0013] Furthermore, a sliding bracket is provided at the bottom end of the clamping plate, and a moving groove is provided at the outer side of the clamping plate.

[0014] Furthermore, a movable rotating shaft is fixedly connected to the outer side of the connecting and fixing plate, and a clamping plate sliding groove is provided at the bottom end of the telescopic bracket.

[0015] Furthermore, a clamping plate is fixedly connected to the bottom end of the clamping plate connecting plate.

[0016] Beneficial effects of the utility model:

[0017] 1. The utility model adopts an adjustable clamping and pulling plate, and uses the position of the pulling plate to match the position of the movable shaft to adjust the clamping depth of the clamping plate, so as to achieve accurate clamping processing for metal injection molded parts of different sizes, with higher flexibility. Compared with the solutions in the prior art, it can more accurately adjust the clamping parts, thereby improving the use efficiency;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A loading fixture for metal parts injection molding, such as Figure 1 As shown, it includes a clamping bracket 1, a control bracket 2 is arranged at the top of the clamping bracket 1, a clamping plate 3 for controlling the entire clamp is arranged at the bottom of the control bracket 2, a telescopic bracket 4 for clamping is slidably connected to the bottom of the clamping plate 3, and a loading clamping plate 5 is fixedly connected to the bottom of the telescopic bracket 4.

[0028] The control bracket 2 at the top of the clamping bracket 1 drives the clamping plate 3 to rise and fall, and the clamping plate 3 drives the telescopic bracket 4, and the loading clamping plate 5 at the bottom of the telescopic bracket 4 is used to process the injection molded parts. When the injection molded product is just formed, the temperature is high and the hardness is not high. The use of adjustable telescopic bracket 4 and loading clamping plate 5 can avoid direct manual contact with high-temperature injection molded parts, and can also clamp injection molded parts of different sizes.

[0029] like Figure 2 As shown, movable brackets 11 are rotatably connected to both sides of the bottom end of the clamp bracket 1, and a movable connecting frame 12 is rotatably connected to the bottom end of the movable bracket 11. A movable hole 13 is opened at the top end of the clamp bracket 1, and a control cylinder 14 is fixedly connected to the top end of the clamp bracket 1.

[0030] The telescopic bracket 4 is supported by the movable bracket 11 and the movable connecting bracket 12 at the bottom of the clamping bracket 1, and the control cylinder 14 at the top of the clamping bracket 1 controls the bracket 2 to move.

[0031] like Figure 3 As shown, the control bracket 2 is fixedly connected to the output end of the control cylinder 14 , the bottom end of the control bracket 2 is fixedly connected to a telescopic movable support rod 21 , and the telescopic movable support rod 21 passes through the movable hole 13 and is fixedly connected to a support rod connecting frame 22 .

[0032] By controlling the support 2 to be pushed by the control cylinder 14, the telescopic movable support rod 21 drives the support rod connecting frame 22, so that the support rod connecting frame 22 drives the clamping plate 3 to be lifted or lowered.

[0033] like Figure 4 As shown, a sliding bracket 31 is provided at the bottom end of the clamping plate 3 , and a moving groove 32 is provided at the outer side of the clamping plate 3 .

[0035] like Figure 4 As shown, the bottom end of the loading clamping plate 5 is fixedly connected to a movable slide 51 , the bottom end of the movable slide 51 is fixedly connected to a clamping plate connecting plate 52 , and the bottom end of the clamping plate connecting plate 52 is fixedly connected to a clamping plate 53 .

The clamping plate slide 44 at the bottom of the telescopic bracket 4 is used to carry the feeding clamping plate 5, so that the position of the clamping plate connecting plate 52 can slide. The clamping plate 53 is selected according to the actual use requirements, and can be made of hard heat-resistant metal parts or flexible materials to prevent marks from being left on the metal injection molded parts that are not fully formed.

[0037] When in use, first select the corresponding clamping plate 53 according to the actual clamping needs, and install it on the outside of the clamping plate connecting plate 52, then select the position of the corresponding loading clamping plate 5 according to the size of the metal injection molded part to be clamped, and use the movable shaft 43 to determine the position of the inner side of the movable groove 32, and then use the nut to fix the position of the movable shaft 43, and then drive the control cylinder 14 to drive the control cylinder 14 to drive the control bracket 2 to rise. During the process, the telescopic movable support rod 21 will be driven, so that the support rod connecting frame 22 moves to the top and drives the movable groove 32. After the movable groove 32 is driven, the telescopic bracket 4 will flip over under the restriction of the movable bracket 11 and the movable connecting frame 12 at its top, and the telescopic bracket 4 drives the clamping plate slide groove 44 to move, so that the loading clamping plate 5 slidingly connected on the inner side is also driven accordingly, so that the clamping plate 53 is flipped over, and the metal injection molded part is clamped.
