Description

Technical Field

[0001] This utility model relates to the field of automotive injection molded parts processing, and in particular to a clamping and fixing tooling for automotive injection molded parts processing. Background Technology

[0002] Automotive injection molded parts refer to automotive components made by injecting molten plastic into a mold through the injection molding process and then cooling and solidifying it. They are widely used in the fields of interior and exterior body trim, power systems, safety structures, and functional components. In the injection molding process, the sprue is the flow channel and residual part of the molten plastic from the injection molding machine nozzle into the mold cavity. In automotive injection molded parts, the "skirt" usually refers to the thin-walled structure extending from the edge of the plastic part.

[0003] After the injection-molded automotive parts with skirts are formed, the sprue head is located at the bottom of the skirt. It is necessary for personnel to use a blade to cut the root of the sprue head to separate it from the skirt. However, the skirt is a thin-walled structure that is easily deformed, and the blade needs to squeeze the skirt when cutting, which can cause the skirt to dent inward, thereby damaging the skirt structure. There is a problem that the skirt is prone to deformation during the sprue head cutting process. To address this issue, a clamping and fixing tooling for processing automotive injection-molded parts is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping and fixing tooling for processing automotive injection molded parts, so as to solve the problem of easy deformation of the skirt during the cutting process of the skirt material head mentioned in the background art. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A clamping and fixing fixture for processing automotive injection molded parts includes an injection molded part body, a base plate provided on the lower part of the injection molded part body, a clamping mechanism for fixing the injection molded part body to the base plate provided on the upper part of the injection molded part body, and a clamping mechanism for clamping the skirt with material head on the side of the injection molded part body.

[0006] Preferably, a positioning groove is provided on the top of the base plate, and a first through hole is provided on both sides of the positioning groove, and the outer contour surface of the injection molded part body is in contact with the surface of the positioning groove.

[0007] Preferably, the clamping mechanism is a pressure plate, with a second through hole at both ends. A screw passes through the second through hole and extends into the interior of the first through hole. The screw is threadedly connected to the first through hole. A limit block is provided in the middle of the pressure plate.

[0008] Preferably, the clamping mechanism includes a guide plate, a connecting rod, and a push plate. The guide plate and the push plate are respectively connected to both ends of the connecting rod. The connecting rod is located between the pressure plate and the injection molded part body. The push plate is in contact with the skirt edge with the material head on the side of the injection molded part body.

[0009] Preferably, the guide plate and the limiting block are connected by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention places the injection molded part body inside the positioning groove on the base plate, and then uses a push plate to press the skirt with the material head on the side of the injection molded part body, so that the skirt fits into the surface of the positioning groove, thereby fixing the shape of the skirt. At this time, the material head and the skirt are separated by cutting the root of the material head with a blade, which can prevent the skirt from being deformed due to excessive compression.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 In this utility model, a clamping and fixing fixture for processing automotive injection molded parts includes an injection molded part body 2, a base plate 1 is provided below the injection molded part body 2, and a pressure plate 3 and a guide plate 4 are provided above the injection molded part body 2.

[0017] A positioning groove 101 is provided on the top of the base plate 1. A first through hole 102 is provided on both sides of the positioning groove 101. After the injection molded part body 2 is naturally placed inside the positioning groove 101, the outer contour surface of the injection molded part body 2 fits against the surface of the positioning groove 101.

[0018] Example 1: Please refer to Figure 1-3 In this embodiment of the utility model, a clamping and fixing fixture for processing automotive injection molded parts is provided. Both ends of the pressure plate 3 are provided with second through holes 302. Screws pass through the second through holes 302 and extend into the interior of the first through hole 102.

The operator can control the movement of the push plate 402 by rotating the bolts 5. The push plate 402 can squeeze the skirt with the material head 201 on the side of the injection molded part body 2, so that the skirt fits against the surface of the positioning groove 101, thereby fixing the shape of the skirt. At this time, the material head 201 and the skirt are separated by cutting the root of the material head 201 with a blade, which can prevent the skirt from being deformed due to excessive compression.
