Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, in particular to a mold structure for a vulcanizing machine. Background Art

[0002] Vulcanizer molds are key tools used in the vulcanization process of rubber products. Vulcanizer molds are mainly divided into open, closed, semi-closed, hinged (hinge) and outer hoop clamping types. Molds with different structures are suitable for different types of rubber products.

[0003] In the existing mold, after the product is placed in the middle template for vulcanization, the upper and lower molds need to be closed to seal the middle template. This causes a certain amount of extrusion on the middle template when the upper and lower molds are closed, resulting in a tighter connection between the middle template and the lower template. As a result, after the product is vulcanized, it is difficult for the staff to remove the middle template from the lower template, which increases the labor intensity of the staff. Therefore, a mold structure for a vulcanizer is proposed to solve the above technical problems. Utility Model Content
