Embodiment 1

[0032] refer to Figure 1-5 , a high-quality injection molding machine for preventing bubble gaps, including a table body 1, a box door 2 and a melting cylinder 13, a support frame 5 is fixedly connected to the top of the table body 1, and the end of the support frame 5 away from the table body 1 is connected to the melting cylinder 13 To form a fixed connection, the box door 2 is hinged on one side of the outer wall of the table body 1, the bottom of the table body 1 is fixedly connected with the base 3, and the top of the melting cylinder 13 is respectively inserted with a feeding pipe 12 and an air pressure gauge 10. The end of the material tube 12 away from the melting cylinder 13 is plugged with a feed hopper 11, the top of the melting cylinder 13 is fixedly connected with a motor 9, one end of the output shaft of the motor 9 is fixedly connected with a rotating column 7, and the outer wall of the rotating column 7 is fixedly connected with a Lifting assembly, one side of...

Embodiment 2

[0037] refer to Figure 6-7 Compared with Embodiment 1, this embodiment also includes that one end of the inner tube 40 is plugged with a dispersing tube 36, and the circumferential inner wall of the dispersing tube 36 is fixedly connected with a dispersing vessel 38, and the mouth of the dispersing vessel 38 is upward, and the opening of the dispersing vessel 38 is upward. Dispersion holes 37 distributed equidistantly are opened on the inner wall of the circumference, and the specifications of the dispersion holes 37 gradually decrease from the side of the dispersion dish 38 to the center of the dish.

[0038] During use, when the injection molding material is ejected from the inside of the inner tube 40 and enters the inside of the dispersion pipe 36, the dispersion dish 38 arranged inside the dispersion pipe 36 and the dispersion hole 37 provided at the bottom of the dispersion dish 38 can be used to spray the raw material close to the injection molding material. Secondary ...

Abstract

The invention belongs to the technical field of injection molding machines, particularly relates to a high-quality injection molding machine capable of preventing bubble gaps. According to the following scheme provided aiming at the problem of poor quality of subsequent injection molding products caused by excessive bubbles contained in injection molding slurry when the injection molding machine performs injection molding work: the injection molding machine comprises a table body, a box door and a melting cylinder, the top of the table body is fixedly connected with a supporting frame, the end, away from the table body, of the supporting frame is fixedly connected with the melting cylinder, and the box door is connected to the outer wall of one side of the table body through a hinge. Bubbles in molten injection molding raw materials can be punctured through steel needles, so that a good defoaming function can be achieved, meanwhile, secondary defoaming treatment can be conducted on the injection molding raw materials through tooth blocks arranged in circular grooves, the defoaming effect of a defoaming assembly on the injection molding raw materials is further improved, and therefore, the production quality of subsequent injection molding products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a high-quality injection molding machine capable of preventing bubble gaps. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. [0003] At present, when most injection molding machines are in use, because most of the time the molten plastic is easily mixed with air bubbles under actual conditions, the molten plastic is directly injected into the closed cavity. It is not contained inside the plastic part, but is exposed on the surface of the plastic, c...
