Processing mold for double-plastic molding of air bracing pipe

Abstract

The invention discloses a processing mold for double-plastic molding of an air bracing pipe, the processing mold comprises an upper mold, a lower mold, a loose core and a plurality of slide blocks, the upper mold and the lower mold are controlled to be opened and closed, the loose core and the slide blocks are arranged between the upper mold and the lower mold, mold cores corresponding to product molding cavities are arranged in the upper mold and the lower mold, and a main glue feeding unit, mold cores and a material pushing unit for demolding are arranged between the upper mold and the lower mold. The processing mold is characterized in that: away from the main glue feeding unit, a molding sliding block used for secondary rubber coating and a secondary glue feeding unit are sequentially arranged on the outer side of the mold core in the lower mold, a primary injection molding groove and a secondary rubber coating molding groove are distributed in the molding sliding block in the sliding direction, a lifting mechanism is arranged between the mold core and the lower mold, on the basis of completing one injection molding, the mold cores, the loose core, the main glue feeding unit and the push plate of the material pushing unit are integrally lifted to make up the displacement space of the molding sliding block, the molding sliding block is made to transversely move, and the forming grooves are switched. By means of the processing mold, injection molding of plastic pipe fittings with different processes and specific material requirements can be achieved through one set of mold, the mold cost is optimized, and energy consumption is reduced.

Description

technical field [0001] The invention relates to an improved mold structure, in particular to a single-set injection mold used for overmolding with different materials. Background technique [0002] Injection molding production is an effective way to mass-customize various special-shaped parts. The development of its process has a long history and is increasingly efficient, environmentally friendly and high-quality. The injection molding process is an optimal process that can meet the processing and production of various non-standard special-shaped parts. Compared with the traditional cutting, punching and milling processing methods, it has a significant advantage of one-time molding and large-scale production. However, due to the shape of injection molding products Diversity, corresponding to a product often requires independent development and repeated trial production to meet the precision requirements of the product before it can be put into large-scale production.
