Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] A molding process for plastic wine glasses, including five processes:

[0021] a. Injection molding: the primary product is obtained by demolding, the cup body is wide at the top and narrow at the bottom or straight, and the bottom is curved to close the bottom;

[0022] b. Mold clamping: transfer the primary product to the blow mold;

[0023] c. Heating: Put the mold with the primary product into the oven for heating, and the softening time is 30-40 seconds;

[0024] d: Blow molding: Blow for 8~12 seconds after closing the mold, and keep the air pressure at 25~28MPa;

[0025] e: demoulding, polishing treatment.

[0026] In this process, in the process of mold clamping, heating and blow molding, the plastic wine glass is in an upside-down state, with the mouth of the cup facing down and the tall part facing up; high-pressure air blows upward from the nozzle o...

Abstract

The invention discloses a molding process for a plastic red wine goblet. The molding process comprises (a) injection molding, (b) mold clamping, (c) heating, (d) blow molding, and (e) de-molding and polishing treatment. In the blow molding process, the plastic red wine goblet is fixed in an inverted way, a goblet opening is downward, a nozzle of a high-pressure blower gun is upward and is used for blowing air to the bottom of a goblet body, and the air is blown for 8 to 12 seconds after die assembly, and the air pressure is kept to be 25-28MPa. In the heating process, a local heating method is adopted, only the middle of the goblet body is heated and softened, and a stem part and the goblet opening are cooled for hardness maintenance thereof. According to the molding process, a bad effect caused by collapsing of the goblet opening in the blow molding process is avoided, an annular rib structure which is added at the goblet opening and is used for fixing the goblet opening is eliminated, the plastic red wine goblet has a good molding effect, and the appearance of the plastic red wine goblet is in full accordance with that of a glass or quartz red wine goblet.

Description

technical field [0001] The invention relates to the field of plastic manufacturing, in particular to a molding process of a plastic wine glass. Background technique [0002] A goblet made of glass or quartz is a special vessel for drinking red wine. The curved shape of the cup, the raised finger rest and the round base have been widely accepted and loved all over the world as a classic design. However, the goblet made of glass or quartz is afraid of being crushed or dropped, and is easily broken. When broken, it may even hurt the user and other people, and there is a potential safety hazard. [0003] Therefore, people are constantly researching and utilizing new materials, such as plastics to make various cups. At present, the common materials used for making plastic cups are non-toxic DPE (polyethylene), PP (polypropylene) and ABS, while PC materials will produce BPA (bisphenol-A) after hydrolysis. Studies in recent years have shown that long-term intake of trace amounts...
