Pneumatic demolding injection molding mold for thermos bottle caps

Abstract

The invention discloses a pneumatic demolding injection molding mold for thermos bottle caps. The pneumatic demolding injection molding mold for thermos bottle caps sequentially comprises a fixed mold and a moving mold; the moving mold comprises a mold leg, an ejection plate, ejector pins, a water distribution plate, a mold core fixing plate, a pushing plate and mold cores; the mold cores are arranged on the mold core fixing plate; the pushing plate is matched with guide rods on the mold core fixing plate in a sliding mode. The pneumatic demolding injection molding mold for thermos bottle caps is characterized in that the mold cores are internally axially provided with air pipes; the end surfaces of the mold cores are provided with air nozzles; one ends of the air pipes are connected with the air nozzles, and the other ends of the air pipes are connected with an air source by air holes in the water distribution plate. Compressed air is sprayed into thermos bottle caps on the mold cores by the air pipes and the air nozzles, so that the thermos bottle caps are removed from the mold to achieve the aim of demolding automatically without manual operation; therefore, the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of molds, in particular to a pneumatic demoulding injection mold for thermos bottle caps. Background technique [0002] As is known, the production and processing of thermos bottle caps generally heat the plastic through an injection molding machine, and then inject the molten plastic into the cavity of the injection mold after plasticization. The injection molding process can be roughly divided into the following six stages: "mold closing- Injection-holding-pressure-cooling-opening-product take-out"; the current thermos bottle cap injection mold generally includes a fixed mold and a moving mold, wherein the moving mold includes mold legs, top plate, thimble, water separating plate, core fixing plate, pusher Plate and core, after the mold is opened, the top plate in the movable mold drives the thimble to push the push plate to push out the thermos bottle cap on the core, but for the needs of injection mold closing, th...
