Description

Technical Field

[0001] This utility model relates to the field of injection molds, and in particular to an injection mold with an automatic waste separation function. Background Technology

[0002] In the box manufacturing process, the most commonly used molding technology is injection molding. This method involves injecting molten thermoplastic or thermosetting plastic into a pre-designed metal mold cavity. After the material cools and solidifies, a plastic box product with precise shape and stable dimensions can be obtained. Due to its high production efficiency, good product consistency, and ability to form complex structures, injection molding has become the mainstream processing method widely used in the modern box manufacturing field.

[0003] In our daily work, we have found that in the injection molding process of box bodies, due to the high temperature and adhesiveness of the plastic melt, the scrap and overflow generated during the injection molding process often adhere firmly to the surface of the mold cavity. This not only increases the difficulty of manual cleaning, but also affects the molding quality and production efficiency of subsequent products. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing box injection molding process, due to the high temperature characteristics and adhesiveness of the plastic melt, the scrap and overflow generated during the injection molding process often adhere firmly to the surface of the mold cavity. Therefore, this invention proposes an injection mold with an automatic scrap separation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an injection mold with automatic waste separation function, including a frame, a first mold fixedly installed on the top of the frame, a guide plate fixedly installed on the top of the first mold, a second mold provided on the top of the first mold, a guide column fixedly installed at the bottom of the second mold that can be slidably connected with the guide plate, and a waste separation component provided on the side of the first mold;

[0006] The waste separation assembly includes a first cylinder, a fixed plate, a sealing door, a first mounting plate, and a second mounting plate. There are two first cylinders, which are symmetrically installed on both sides of the first mold. There are four fixed plates, which are symmetrically installed on the top of both sides of the first mold. An opening is provided at the bottom of the first mold, and the sealing door is installed on the surface of the opening. The first mounting plate and the second mounting plate are both fixedly installed at the bottom of the first mold.

[0007] As a further embodiment of this utility model, a first scraper is fixedly installed on the piston end of the first cylinder, and the first scraper is slidably connected to the inner wall surface of the first mold.

[0008] As a further embodiment of this utility model, a limiting block and a rotating shaft are fixedly installed on the surface of the fixing plate, and a limiting rod is slidably connected to the surface of the limiting block.

[0009] As a further embodiment of this utility model, a second scraper is provided on the side of the limiting rod near the first mold. The second scraper is slidably connected to the inner wall of the first mold, and a protruding plate is fixedly connected to one side of the second scraper. The protruding plate is fixedly connected to the limiting rod.

[0010] As a further embodiment of this utility model, a second cylinder is fixedly mounted on the surface of the first mounting plate, and a receiving block is fixedly mounted on the piston end of the second cylinder. Two first connecting rods are rotatably connected to the surface of the receiving block, and the two first connecting rods are symmetrically arranged.

[0011] As a further embodiment of this utility model, a slide rail is fixedly installed on the surface of the second mounting plate, and two sliders are slidably connected to the surface of the slide rail. The sliders are rotatably connected to the end of the first connecting rod away from the receiving block. A receiving plate is fixedly connected to the end of the sliders, and a second connecting rod is fixedly installed on the top of the receiving plate. A third connecting rod is rotatably connected to the top of the second connecting rod, and a fourth connecting rod is rotatably connected to one end of the third connecting rod, and a fifth connecting rod is rotatably connected to the other end.

[0012] As a further embodiment of this utility model, the end of the fourth link is rotatably connected to the surface of the rotating shaft, and the fifth link is rotatably connected to the surface of the convex plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the second cylinder pulls the receiving block to deflect the two first connecting rods. The first connecting rods drive the two sliders to slide along the slide rail surface, thereby causing the two second connecting rods to move inward. Under the push of the third and fourth connecting rods, the fifth connecting rod deflects, thereby pushing the second scraper. The second scraper can scrape off the waste material adhering to the surface of the first mold. Finally, the two first cylinders are driven, and the first scraper scrapes off and pushes the waste material through the sealing door to separate the waste material, thereby cleaning and separating the waste material.

[0026] Working principle: The second cylinder 441 pulls the receiving block 442, causing the two first connecting rods 443 to deflect. The first connecting rods 443 drive the two sliders 452 to slide along the surface of the slide rail 451, thereby causing the two second connecting rods 461 to move inward. Under the push of the third connecting rod 462 and the fourth connecting rod 463, the fifth connecting rod 464 deflects, thereby pushing the second scraper 47. The second scraper 47 can scrape off the waste material adhering to the surface of the first mold 2. Finally, the two first cylinders 41 are driven, and the first scraper 411 scrapes off and pushes the waste material through the sealing door 43 to separate the waste material, thereby cleaning and separating the waste material.
