[0001] The utility model relates to the technical field of mold injection molding, in particular to an automatic mold injection molding device. Background Technique

[0002] For products formed by automatic mold injection molding, especially slender bodies, they are small in volume and light in material. When demolding, the shaping rod of the mold retracts, and the injection molded product will not fall off. Therefore, external force is required. Some enterprises, for the sake of convenience, directly install a lifter above the mold demolding structure and install devices such as brushes below the lifter to brush the injection molded product down along the surface of the template. Such a design is relatively complicated and not simple enough. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic mold injection molding device to solve the problem of brushing the injection molded product down along the surface of the template as mentioned in the above background technique. Such a design is relatively complicated and not simple enough.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An automatic mold injection molding device includes an injection molding mating mold. Perforations are arranged in a matrix on the injection molding mating mold. A displacement module is provided on the back of the injection molding mating mold. A shaping column passing through the perforations is fixedly installed on the displacement module. A front edge protrudes outward from the side of the injection molding mating mold. A hollow air blowing part is provided at the top of the front edge. An air pipe connection port is connected and installed on the outside of the hollow air blowing part. Telescopic tubes are fixedly installed at the top and bottom on both sides of the front edge. A flexible baffle is provided between the upper and lower telescopic tubes. Fixing strips are fixedly installed on the sides of the telescopic tubes and the flexible baffle.

[0006] As a further description of the above technical solution:

[0007] The length of the shaping column is greater than the length of the perforation.

[0008] As a further description of the above technical solution:

[0009] The telescopic tube is made of high-temperature resistant material.

[0010] As a further description of the above technical solution:

[0011] The telescopic tube is a corrugated tube.

[0012] As a further description of the above technical solution:

[0013] The flexible baffle is grid-shaped.

[0014] As a further description of the above technical solution:

[0015] Mounting holes are formed at the top and bottom of the fixing strip.

[0016] Compared with the prior art, the utility model provides an automatic injection molding device for a mold, which has the following beneficial effects:

[0017] 1. In the utility model, by improving the structure of the injection molding and closing die, and adding a front edge, the injection molded products that have not fallen off can be blown off.

[0018] 2. In the utility model, the telescopic pipe and the flexible baffle are designed to prevent the injection molded products blown off from floating out from both sides. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 2 , the utility model provides an automatic injection molding device for a mold, including an injection molding and closing die 1, through holes are formed in a matrix on the injection molding and closing die 1, a displacement module 2 is arranged on the back of the injection molding and closing die 1, a shaping column 3 passing through the through holes is fixedly installed on the displacement module 2, a front edge 4 protrudes outward from the side of the injection molding and closing die 1, a hollow air blowing part 5 is arranged on the top of the front edge 4, an air pipe connection port 6 is communicated and installed on the outside of the hollow air blowing part 5, telescopic pipes 7 are fixedly installed on the top and bottom on both sides of the front edge 4, a flexible baffle 8 is arranged between the telescopic pipes 7 at the upper and lower positions, and a fixing strip 9 is fixedly installed on the side of the telescopic pipes 7 and the flexible baffle 8.

[0026] Specifically, the length of the shaping column 3 is greater than the length of the through hole, which is convenient for manufacturing plastic products.

[0027] Specifically, the telescopic tube 7 is made of high-temperature resistant material. The telescopic tube 7 is a corrugated tube with a long service life, a small degree of stretching, concave bending, and does not affect contraction.

[0028] Specifically, as Figure 1 shown, the flexible baffle 8 is grid-shaped, saving materials and not being affected by extrusion and contraction.

[0029] Specifically, as Figure 1 shown, mounting holes are provided at the top and bottom of the fixing strip 9 for convenient installation.

[0030] Working principle:

[0031] The injection molding die 1 contacts the injection part of the injection molding machine. The displacement module 2 moves forward, and the shaping column 3 extends out of the perforation of the injection molding die 1. The injected plastic material is coated on the position where the shaping column 3 extends to form a thin and light injection molded product. The fixing strip 9 is fixed to the injection part of the injection molding machine with screws. The injection molding die 1 and the displacement module 2 retreat, driving the injection molded product to retreat. Then the displacement module 2 retreats, and the shaping column 3 withdraws from the injection molded product and then hides at the perforation position. At this time, some of the injection molded products fall off, and some are still on the injection molding die 1. The air pipe connected to the air pipe connection port 6 conveys the air flow to the hollow air blowing part 5 at the front 4 to blow and drop the injection molded products. At this time, due to the retreat of the injection molding die 1 and the displacement module 2, the telescopic tube 7 and the flexible baffle 8 unfold, so that the blown plastic products will not float out from the side.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
