Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to a positioning device for an injection mold of a plastic product. Background Art

[0002] With the rapid development of the plastics industry and the continuous improvement of plastics performance, plastic parts have been more widely used. Plastic parts are replacing traditional metal parts in different fields. A well-designed plastic part can often replace multiple traditional metal parts, thereby simplifying product structure and saving manufacturing costs.

[0003] At present, existing plastic products are usually manufactured by injection molding. During the injection molding process, the injection mold needs to be manually placed on the injection molding station accurately, and then the injection mold is fixed with screws or bolts. After the fixation is completed, the injection molding operation is performed. This fixing method not only has low installation efficiency, but also is inconvenient to disassemble and assemble. After the bolts and other fixing parts are disassembled and installed many times, wear will occur between the threads, making the injection mold positioning unstable and inaccurate, affecting the quality of the injection molded product. In addition, the injection mold is generally divided into a lower mold and an upper mold. Generally, during injection molding, the upper mold is generally in a free state, which also affects the quality of the injection molding.

[0004] Based on this, the utility model designs a positioning device for an injection mold of a plastic product to solve the above problems. Utility Model Content
