Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to a fixture structure for auxiliary material discharge. Background Art

[0002] Rubber product molds are divided into four common molds according to the mold structure and product production process: compression molding molds, die-casting molding molds, injection molding molds, extrusion molding molds, and some special rubber product molds for producing special rubber products, such as inflation molds, dipping molds, etc.

[0003] The compression molding die is also called a transfer die or an extrusion die. It puts the mixed, simple-shaped, limited rubber or rubber block semi-finished product into the die-casting mold cavity, squeezes the rubber through the pressure of the die-casting plug, and allows the rubber to enter the mold cavity through the pouring system for vulcanization and shaping.

[0004] In the processing of some existing rubber products, the raw materials need to be cut into strips, clamped into rings that match the mold, and then placed in the mold cavity for vulcanization molding. Since each hole needs to be placed with a ring, the number of holes is relatively large, and the placement process takes a long time. In addition, the placement time is too long, which causes the rubber raw materials placed in the mold cavity to be vulcanized prematurely and produce dead materials. At the same time, the placement time is long, and the materials placed in the mold cavity absorb heat and vulcanize inconsistently, resulting in different degrees of product vulcanization and product quality differences. Therefore, it is necessary to provide a fixture structure for auxiliary placement. Utility Model Content
