Blow molding mold special for clothing prop for stage

Abstract

The invention discloses a clothing prop special-purpose blowing mold, including a mold cavity with molding surface, and inlay piece inlaid on the mold cavity, wherein, the front-end of the inlay piece is provided with a molding surface constituting a part of the molding surface of the mold cavity, the molding surface of the inlay piece has a corner to the molding surface of the mold cavity neighbored to molding surface of the inlay piece, and a gap is provided at the connecting point of the mold cavity and the inlay piece; a boss facing to the inside of the mold cavity is also provided on the molding surface of the mold cavity, the inlay piece or boss is connected to a reciprocating drive device which drives it to move forward to the mold cavity direction before blowing and resets after the blowing is fulfilled, and the height of the boss is smaller than or equal to the moving distance of the boss under the function of the reciprocating drive device. Use of the mould can form corners at the members of the clothing props to realize the perfect connection between each member of the clothing props, and can directly form a reentrant at the connection surface, to achieve the structurally integrity and use requirements of the clothing models, thereby further improving the blowing process of the clothing props and having high capacity and low cost.

Description

technical field [0001] The invention relates to a blow mold, in particular to a special blow mold for clothing props. technical background [0002] Plastic blow molding is a method of forming hollow products, and blow molding products are more and more widely used in daily production and life. The blow molding process consists of two basic steps: first forming the parison, and then blowing the parison with compressed air to make it close to the mold cavity, giving the shape and size of the cavity to the product. Blow molding can form large and hollow products that cannot be produced by other methods with high production efficiency. However, for hollow products formed by blow molding, due to the limitations of the process, the corners, corners, grooves and ribs of the product should be as large as possible to form a large arc or spherical transition, because the parison under the action of compressed air , the force on all directions of the mold cavity is equal, when there ...

AI Technical Summary

Problems solved by technology

Since these holes or cavities cannot be formed at the same time as the prop parts, they need to be reprocessed in the subsequent process, so the production efficiency is reduced and the manufacturing cost is also increased.
