Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding equipment, in particular to a novel mold glue inlet structure. Background Art
[0002] Injection molding is a production method for plastic products. The molten injection molding material is injected into the mold cavity of the plastic product by pressure, and various injection molding products are obtained after cooling and molding. The injection molding material is transported from the feeding system to the pouring system and finally reaches the mold cavity. Inside the pouring system, the injection molding material must first flow through the main channel, and then be pressed into each branch channel by pressure, and finally enter the mold cavity through the branch channel for molding. After the injection molding material in the flow channel and the mold cavity cools down, the formed plastic component including the finished product and the connecting part will be ejected from the mold cavity, and the connecting part is formed by the injection molding material injected into the flow channel after cooling. After that, the connecting part is cut and separated from the finished product to obtain the final injection molding product.
[0003] However, the existing multi-cavity injection molds have glue inlets that are mostly pointed and sharp. They are prone to overcutting during cutting, which can easily cause the glue inlets to wear out after molding and become uneven in size, seriously affecting product size and appearance, and have certain limitations. Utility Model Content
[0004] In view of the above problems, the utility model proposes a new type of mold glue inlet structure to solve the problem proposed in the above background technology that the existing multi-cavity injection molds have glue inlets that are mostly in the shape of pointed holes, which are sharp and easy to overcut, and easily cause the glue inlets to wear out after molding, resulting in uneven sizes, seriously affecting the product size and product appearance, and having certain limitations.
[0005] The technical solution of the utility model is:
[0006] A novel mold glue inlet structure comprises an injection channel, wherein the lower end of the injection channel is connected with a glue inlet pipe, the lower end of the glue inlet pipe is fixedly connected with a glue lowering port, the lower end of the glue lowering port is fixedly connected with a glue lowering straight port, and the lower part of the glue lowering straight port is connected with an injection molded part.
[0007] The working principle of the above technical solution is as follows:
[0008] The molding liquid is diverted to the inside of each glue inlet pipe for injection molding through the set injection channel, and the molding liquid is injected into the injection molded part through the glue lower straight port. A glue lower straight port is added at the lower end of the glue lower port, and the processing is performed by cutting along the plane of the glue lower straight port with a slow-feeding wire with better precision. The cutting surface can be neat, the glue port cut surface is flat and consistent, and the product quality and appearance are better, which solves the technical problem that the flatness of the cut cannot be well guaranteed in the prior art.
[0009] In a further technical solution, there are two groups of injection molding runners, and the number of injection molding runners in each group is three.
[0010] The arrangement of multiple branch runners facilitates multi-hole injection molding, improves injection molding efficiency, and solves the technical problem of low injection molding efficiency in the prior art.
[0011] In a further technical solution, there are two groups of the glue inlet pipes, each group of the glue inlet pipes has ten glue inlet pipes, and the injection runner is connected to the glue inlet pipes through a diverter pipe.
[0012] The provided glue inlet pipe facilitates multi-hole injection molding, thus solving the technical problem of low injection molding efficiency in the prior art.
[0013] In a further technical solution, the length of the straight opening for glue lowering is 0.1 mm.
[0014] By adopting a 0.1mm straight bottom glue mouth, the cutting can be flush with the lower end of the straight bottom glue mouth, thereby ensuring a smooth incision, which solves the technical problem that the smoothness of the incision cannot be well ensured in the prior art.
[0015] The beneficial effects of the utility model are:
[0016] 1. The utility model adds a straight glue opening at the lower end of the glue opening, and uses a slow-feeding wire with better precision to cut along the plane of the straight glue opening for processing, so that the cutting surface can be neat, the glue opening cut surface can be flat and consistent, and the product quality and appearance can be better.
