A special blow molding mold for clothing props

Abstract

The invention discloses a special blow moulding mould for clothing props, comprising a mould cavity with a moulding surface, the mould cavity is inlaid with an insert, the front end of the insert is provided with a moulding surface which constitutes a part of the moulding surface of the mould cavity, the moulding surface of the insert is There is a corner between the molding surface adjacent to the surface on the mold cavity, and a gap is provided at the junction between the mold cavity and the insert; the molding surface of the insert is also provided with a boss facing the interior of the cavity, and the insert Or the boss is connected with a reciprocating drive device that drives it to move in the direction of the cavity before blowing and resets after blowing, and the height of the boss is less than or equal to the distance the boss moves under the action of the reciprocating drive device. Using this kind of mold, corners can be formed on the parts of the costume props, the perfect connection between the parts of the costume props can be realized, and a cavity can be directly formed on the connecting surface to meet the structural integrity and use requirements of the costume model. The blow molding process of costume props is further improved, and the production capacity is high and the cost is low.

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 ...

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.
