Rubber mould self-adaptive regulator for producing rubber product with metal frame

Abstract

The invention discloses a rubber mould self-adaptive regulator for producing a rubber product with a metal frame, comprising an upper fixing plate, a lower fixing plate, an upper mould, a lower mould, a half component and a core embedded block, wherein the upper mould and the lower mould are respectively connected with the upper fixing plate and the lower fixing plate, the half component is arranged between the upper mould and the lower mould, the core embedded block is mated with the half component, a groove is arranged on the lower fixing plate, and a thermal expansible body is arranged in the groove. According to the rubber mould self-adaptive regulator for producing the rubber product with the metal frame, disclosed by the invention, through utilizing the characteristic of thermal expansion and cold contraction of the thermal expansible body and the expandable function of a material, an interval between a core and a mould due to plus-minus tolerance of the core is regulated self-adaptively when a mould cavity of a rubber mould is heated after a metal core is arranged in the mould cavity of the rubber mould, thus leakage of rubber materials from the interval can be reduced, the size fluctuation of the rubber product can be reduced, the quality of the rubber product is improved, and the service life of the rubber mould can be also prolonged.

Description

technical field [0001] The invention relates to a mold device, in particular to a rubber mold self-adaptive adjustment device for producing rubber products with metal skeletons. Background technique [0002] In the production process of rubber products with metal skeleton, due to the error of gold processing, the size error of rubber mold must exist. Affected by a series of conditions such as current processing technology, processing equipment, human factors, and material factors, rubber molds The size of the product cannot be controlled, and in the production process, due to the inconsistency of the size of the product skeleton, the size of the produced product will be different. If it is produced for a long time, the size of the mold will also change, causing losses to the enterprise and increasing the rubber The loss of raw materials increases the reject rate of products. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies...
