Embodiment Construction

[0011] Such as figure 1 , figure 2 , image 3 As shown, a goblet molding process: a. According to the design of the product injection mold, the cup body of the primary product is wide on the outside and narrow on the inside, which is easy to demould; The top is wide and the bottom is narrow, and the outer edge of the primary product is 0.5 to 0.8 mm more exposed than the actual product; C. Ultraviolet heating, heating the primary product at 180 ° C to 260 ° C for 10 to 30 seconds to soften the primary product, and then place it In the blow mold; d, blow molding, blowing air for 8-12 seconds after closing the mold, the air pressure is kept at 25-28Mpa, to obtain a cup body with a wide middle and narrow ends, stop blowing, and demould to obtain a product. The injection mold is composed of an upper mold 1 and a lower mold 2. The gap formed after the upper mold 1 and the lower mold 2 are closed is the molding space of the primary product. The cup body of the primary product is ...

Abstract

The invention relates to the field of plastics, in particular to a process for moulding a goblet. The process comprises the following steps of: a. designing an injection mold according to a product, wherein the goblet body part of a primary product is of a structure with a wide outer part and a narrow inner part and is convenient for demoulding; b. injecting for moulding and demoulding to obtain the primary product, wherein the goblet body is of a shape which is wide in the upper part and is narrow in the lower part, and the outer edge of the primary product is 0.5-0.8mm longer than that the practical product; c. ultraviolet heating: heating the primary product at 180-260 DEG C for 10-30 seconds so that the primary product is softened and then introducing the primary product into a blowing mould; d. blowing for moulding: blowing air for 8-12 seconds after compounding and maintaining the pressure to 25-28MPa to obtain the goblet body which is wide in the middle and is narrow at both ends; and stopping blowing air, demoulding and moulding to obtain a product. The moulding process can be used for producing the goblet for integrating the goblet body and the goblet; and the goblet body of the goblet is wide in the middle and is narrow at both ends, thus the processing operation is simple and the processing cost is low and the bonding procedure of the goblet body and the high foot body is reduced.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an integral molding process of a goblet. Background technique [0002] Because the center of the cup body is wide and the two ends are narrow, if one-time injection molding is used, the mold core cannot be separated, so it cannot be one-time injection molding. The cup body and the tall part are injection molded separately at one time, and then the cup body is stretched and blown. But the bottom of the cup body is easy to generate air bubbles, and the cup body and the tall body are easily bent to produce defective products when bonding. Contents of the invention [0003] The object of the present invention is to provide a goblet molding process, which can make the cup body with a wide middle and narrow ends at both ends integrally formed with the goblet body. [0004] The overall molding process of the goblet: a. Mold design, the injection mold is designed according to the product, the...
