Injection molding rubber coating mold for rubber tubing

Abstract

The invention discloses an injection molding rubber coating mold for a rubber tubing. The mold comprises a movable mold, wherein a mold cavity for placing a to-be-coated tube piece is arranged on themovable mold, and telescoping mechanisms, capable of stretching and retracting in the radial direction of the mold cavity, are arranged on the movable mold and located at the two side of the mold cavity of the movable mold. According to the mold, the telescopic mechanisms, capable of stretching and retracting in the radial direction of the mold cavity, are arranged on the two sides of the mold cavity of the movable mold, the to-be-coated tube piece is fixed in the mold cavity in advance before the mold closing process through the telescopic mechanisms, so that the situation that in the mold closing process, the tube piece causes the deviation of a product assembly placed in the mold cavity, and then a product is pressed, damaged and scrap is avoided, the appearance quality and size stability of the product are effectively guaranteed, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an injection-coated rubber tube type mold. Background technique [0002] Traditional injection rubber-coated rubber tube molds generally adopt the positioning of the mold body itself, and the CNC program is compiled according to the three-dimensional shape, and the machining center is used to directly process the special-shaped cavity of the rubber tube body on the mold body and then assemble the pipe body for production. This makes the following problems common in injection-molded rubber tube molds: In the production process, due to the need to assemble the injection joints and rubber tubes into the mold body after assembly, there is a large difference in positioning, and the tube body itself is deformed, resulting in pressure after mold closing. Damage to the rubber tube body, the product will leak glue after injection molding, the product lagging offset size is unstable, the pr...

This makes the following problems common in injection-molded rubber tube molds: In the production process, due to the need to assemble the injection joints and rubber tubes into the mold body after assembly, there is a large difference in positioning, and the tube body itself is deformed, resulting in pressure after mold closing. Damage to the rubber tube body, the product will leak glue after injection molding, the size of the product’s rubber offset is unstable, and the production pass rate will be reduced, resulting in an increase in the production cost of product scrapping
