Quantitative feeding and forming device and method for injection molding

Abstract

The invention relates to a quantitative feeding and forming device and method for injection molding, the quantitative feeding and forming device for injection molding comprises a base, a vertical plate fixedly installed on the base, a shell fixedly installed on the vertical plate and a melting barrel rotationally installed on the shell, a driving assembly is installed on the base, and the vertical plate is fixedly installed on the base. The driving assembly drives the extrusion assembly to move, and the extrusion assembly drives the rotating shaft and the melting barrel to rotate through the first transmission assembly, so that the melting effect of plastic particles in the melting barrel is greatly improved, the uniformity of molten materials is guaranteed, and meanwhile, the rotating shaft drives the material conveying structure to move through the second transmission assembly; according to the plastic pipe forming device, the melt in the melting barrel intermittently and quantitatively flows into the shell to be extruded, so that the problem of caking of the melt in the shell is effectively prevented, after the melt is extruded into a pipe shape, the driving assembly drives the cooling assembly to work, the cooling assembly cools a plastic pipe, and finally, the effective forming function of the device on the plastic pipe is achieved.

Description

technical field [0001] The invention relates to the related technical field of plastic molding equipment, in particular to a quantitative feeding molding device and method for injection molding. Background technique [0002] The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of plastics with no or few additives, such as plexiglass. [0003] The existing plastic molding devices used in the production and processing process usually have a poor melting effect on plastic particles, resulting in the plastic pipes not being able to meet the ideal requirements, and ...

Problems solved by technology

[0003] The existing plastic molding devices used in the production and processing process usually have a poor melting effect on plastic particles, resulting in the plastic pipes not being able to meet the ideal requirements, and because the molten material is squeezed at one time, it is easy to produce knots. The problem of block, resulting in poor molding effect of the final plastic pipe
