Description

Technical Field

[0001] The utility model belongs to the field of molds, and in particular relates to a precision-adjustable molding mold. Background Art

[0002] Injection molding is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] The molding mold is the equipment used in the injection molding process, which includes an upper mold and a lower mold. The upper mold and the lower mold are closed and hot-melt material is injected. After cooling, the upper mold and the lower mold are opened to complete the processing and take out the product.

[0004] In addition, as the product structure becomes more complicated and only simple fixed upper and lower molds are used to process the product, it is usually necessary to slide a horizontal module on the lower mold, and correspondingly, a mold closing guide rod needs to be fixed on the upper mold, so that during the mold closing process of the upper and lower molds, the mold closing guide rod is inserted into the alignment hole of the horizontal module to guide the horizontal module to the mold closing position, and during the mold opening process of the upper and lower molds, the horizontal module is guided to the mold opening position by the return spring, and the stability of the horizontal module is maintained under the action of the positioning part and the return spring.

[0005] Due to the structural differences of different products, there are larger horizontal modules, and the required driving force is relatively large. In order to prevent the mold guide rod from breaking and to ensure the effectiveness of the horizontal module movement, it is usually necessary to set up multiple mold guide rods, usually 3-5 pieces.

[0006] However, the setting of multiple mold guide rods will appear in the mold closing process, and each position needs to be aligned with the alignment holes on the horizontal module, so the design precision requirements are too high and the defective rate is too high. Utility Model Content
