Abstract

The invention discloses an extrusion forming device for an injection mold. The device comprises an upper mold and a lower mold, the middle of the bottom end of the upper mold and the middle of the top end of the lower mold are provided with a fixed base and a base correspondingly through mold cavities, an upper mold core is installed in the middle end of the bottom of the fixed base, a lower mold core is installed in the middle end of the top of the base, a mounting groove is formed in the middle end of the top of the base, the outer portion of the top end of the base is provided with a protection sleeve in a threaded manner, multiple bushings are arranged in the protection sleeve in a sleeved manner, the lower mold core is arranged in the protection sleeve, the forming device can adapt to machining needs of different injection molding products, under the condition of not replacing the mold core, the injection molding products in different sizes can be machined, the machining precision is high, adjusting is rapid and convenient, and operation is easy. Use cost is saved, production cost is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to extrusion molding equipment, in particular to an extrusion molding equipment for injection molds and a working method thereof, belonging to the application field of injection molding molds. Background technique [0002] Injection molds are usually used to make various injection molding products. After the injection molding material is placed inside the mold, the inner material is extruded into the desired shape by extrusion molding equipment. [0003] However, the extrusion molding equipment inside the existing injection mold still has certain deficiencies in use. The Chinese patent with the application number 201720104820.4 discloses processing and molding equipment for injection molds. The molding equipment in this patent is relatively fixed in the internal position of the mold, which is inconvenient to adjust. The size and position of a molding equipment are fixed, and only one product can be processed. . When other produc...
