Description

Technical Field

[0001] This utility model relates to the field of denture manufacturing technology, and more specifically, to a resin tooth injection molding device. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Injection molding machine is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through injection molding machine and mold. Resin teeth are mass-produced through injection molding machine.

[0003] For example, the patent disclosed in prior art announcement number CN214419284U discloses a melamine resin injection molding device. The melamine resin raw material is fed into the feed port of the crushing box. At the same time, the first motor drives the rotating spindle to rotate. The rotating spindle drives the crushing blades to cut and crush the poured melamine resin raw material, which then falls into the bottom of the crushing box and into the injection molding assembly through the injection pipe. The powdered melamine resin raw material reduces the injection time and heating time, and improves the working efficiency. After the melamine resin injection is completed, the demolding cylinder is activated. The telescopic end of the demolding cylinder moves backward, pulling the second injection mold to slide backward on the slider, so that the cured melamine resin falls from the first injection mold into the transport assembly, which facilitates the subsequent cooling work.

[0004] When the above-mentioned device is in use, the rotating spindle drives the crushing blades to cut and crush the poured melamine resin raw material, which then falls to the bottom of the crushing chamber and into the injection molding assembly through the injection pipe. The powdered melamine resin raw material reduces the injection molding time, shortens the heating time, and improves the working efficiency. However, it is easy to cause vibration when crushing the resin raw material, which affects the stability of the injection molding. It is inconvenient to operate when injection molding different dentures, which affects the efficiency of resin denture injection molding production. Utility Model Content
