Hot press molding system and method of shell dental instrument scale production

Abstract

The invention provides a hot press molding system and method of shell dental instrument scale production. The hot press molding system includes a coil material supply module, a material heating module, a dental cast loading and unloading module, a pressure molding module and a cutting module, wherein the coil material supply module is used for continuously feeding and receiving raw materials in the form of coil materials; the material heating module is used for heating raw material diaphragms from the upper and lower sides or one side; the dental cast loading and unloading module is used for automatically feeding more than one lower molds loaded with personalized dental models into the pressure molding module, the lower molds are transferred out of the forming station after completing hotpressing, molding, cooling and demoulding, and the subsequent lower molds are continuously and automatically fed and recycled; the pressure molding module is used for pressing and molding the heated and softened diaphragms through more than one upper and lower molds, and one-time molding of multiple products is supported by pressing and molding; and the cutting module is used for cutting a hot press molded appliance to remove peripheral materials. According to the hot press molding system and method of shell dental instrument scale production, the degree of automation is high, and labor costsare lowered; and in addition, through once molding of the multiple molds, the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a thermocompression forming system and method, in particular to a thermocompression forming system and method for large-scale production of shell-shaped dental instruments. Background technique [0002] Polymer shell-shaped dental instruments (invisible aligners, invisible retainers, cosmetic braces, sports protective braces and other functional braces) are highly customized products, which generally use thermoplastic polymer materials and are molded by thermoplastic pressure. Craft method production. The basic process of hot pressing generally includes the following steps: 1. Heat and soften the polymer material diaphragm; 2. Clamp the upper and lower molds, place the polymer material diaphragm on the upper mold, and place the jaw model on the lower mold; 3. Press molding; 4. Cooling under pressure; 5. Opening the mold; 6. Cutting the formed diaphragm. [0003] At present, most of the thermoforming equipment used to make suc...

AI Technical Summary

Problems solved by technology

The existing thermoforming equipment has a large workload and high labor intensity for manual operation, and only one brace can be formed in one process, so the efficiency is low

There are also automatic dental braces hot-press forming machines in foreign countries. Although manual loading and unloading operations are omitted, only one brace can be formed at a time, and the price is expensive and the cost performance is low.
