Problems solved by technology

[0003] In the actual application process, due to the defects of the mold design, it is easy to have bubbles and unevenness on the surface of the molded product in the actual mass production process of this mold, which reduces the yield of the product. Since it occurs in the mass production process, this will Will cause a large waste of raw materials
[0004] In addition, when the existing milk tea cup lid is processed with a blister mold, the processed cup lid is easy to fall from the milk tea cup

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] In the existing mold, the cup lid is generally processed by the blister forming process, and the plastic sheet is heated and softened by the thermoforming method, and deformed by the principle of vacuum (downward suction) with the help of small air holes on the mold Afterwards, it is pasted on the contour surface of the mold, cooled and shaped to form a cup lid.

[0022] see figure 1 , a blow molding mold provided by the present invention, which adopts blow molding to process the cup cover, softens the plastic sheet by heating, blows down through the air pressure principle, deforms it and sticks it on the specific mold contour surface After cooling and shaping, the cup lid is formed.

Abstract

The invention discloses a blowing die. The blowing die comprises a milk tea cup cover die body which is a cylinder with an open-ended bottom; the side surface of the die body is provided with at least one square groove; the bottom of the die body is provided with a first annular edge and a second annular edge; the first annular edge is a cylinder with an open-ended top and an open-ended bottom, the upper opening of the first annular edge is provided with a first connection edge, and the first connection edge is connected with the bottom edge of the die body; the second annular edge corresponds to the first annular edge and is also a cylinder with an open-ended top and an open-ended bottom, the upper opening of the second annular edge is provided with a second connection edge, and the second connection edge is connected with the bottom edge of the first annular edge. The blowing die has the advantages of easy molding, uniform thickness and conservation of materials.

Description

technical field [0001] The invention relates to a mold, in particular to a blow mold. Background technique [0002] Blister mold refers to the mold used in the production of blister. The lowest cost is the plaster mold, followed by the electroplating copper mold, and the most expensive is the aluminum mold. The mold is drilled with small holes, which are used to vacuum heat the hard sheet to form a blister product. [0003] In the actual application process, due to the defects of the mold design, it is easy to have bubbles and unevenness on the surface of the molded product in the actual mass production process of this mold, which reduces the yield of the product. Since it occurs in the mass production process, this will Can cause greater waste of raw materials. [0004] In addition, when the existing milk tea cup lid is processed by using a blister mold, the processed cup lid is easy to fall off from the milk tea cup. Contents of the invention [0005] The technical pr...
