Abstract

A pneumatic type mold capable of easy demoulding is disclosed, and belongs to the technical field of molds. The mold includes a main mold and a subsidiary mold. A pipe is fixedly connected to the topend of the subsidiary mold. The middle of the subsidiary mold is provided with a blow port, the bottom of the subsidiary mold is provided with a subsidiary mold slot, one side of the subsidiary mold is provided with subsidiary mold limiting bar holes, and the inner walls of the subsidiary mold limiting bar holes are movably connected to limiting bars. The upper ends of the limiting bars are movably connected to nuts. One side of the main mold is provided with main mold limiting bar slots. The top ends of the main mold limiting bar slots are fixedly connected to sealing rings. The outsides of the sealing rings are provided with sealing ring holes. The lower ends of the limiting bars pass through the sealing ring holes. Through air outlets in the bottoms of air pumps, the air pumps can blowair to air pipes fixedly connected to the inner walls of the air outlets, thus overcoming a problem that the demoulding efficiency of present molds is low so that demoulding is inconvenient.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a pneumatic mold for easy demoulding. Background technique [0002] Blow molding The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while it is hot or heated to a softened state. After the mold is closed, compressed air is injected into the parison to blow the plastic parison It swells and clings to the inner wall of the mold, and after cooling and demoulding, various hollow products can be obtained. [0003] However, the existing blow molds are not easy to demould because of the slow demoulding efficiency after blow molding, thereby affecting the work efficiency in the production process. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a pneumatic mold for easy demoulding, which solves the problem of inconv...
