An injection molding device for plastic products that prevents air bubbles

Abstract

The invention discloses a plastic product injection molding device for preventing generation of bubbles. The device comprises an upper mold; a lower mold is arranged under the upper mold; and the upper end of the upper mold is penetrated through the inside of a support plate; the upper end of the support plate is connected with a micro pump, and the upper end of the micro pump is connected with aplastic storage box; the outer surface of the plastic storage box is tightly fit to a lagging casing, and the lower end of the lagging casing is welded with a fixed groove; the fixed groove is internally provided with a heating device; a water tank is arranged above the lagging casing; the water tank is connected with the plastic storage box through a connection pipe; corners at the lower end of the support plate are all provided with an electric expansion link; the lower end of the electric expansion link is connected with the lower mold; the corner of the lower mold is provided with a groove. The plastic product injection molding device for preventing generation of bubbles is convenient for pyrolysis and water evaporation of plastic, avoids bubbles when hot pressing to affect use, and meanwhile is convenient for quickly separating the upper and lower molds, thereby improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of injection molding of plastic products, in particular to an injection molding device for plastic products that prevents air bubbles from being generated. Background technique [0002] With the development of science and technology, plastic and rubber products are more and more widely used in people's lives, and people's demand for them is also increasing. At present, plastic and rubber products are generally manufactured by injection molding. Existing injection molding devices The structure is complicated, the operation is cumbersome, the injection molding efficiency is low, and air bubbles are prone to appear after the injection molding is completed, which affects the normal use of plastics and also affects the quality of plastics. Therefore, an injection molding device for plastic products that prevents air bubbles is needed to solve the above problems. Contents of the invention [0003] (1) Solved tec...
