Rotary mold injection molding and cooling forming equipment for plastic particles

Abstract

The invention discloses rotary mold injection molding and cooling forming equipment for plastic particles. The equipment structurally comprises a machine base, a feeding box, a control panel and a discharging device, wherein the feeding box is arranged at the top end of the machine base, the control panel is located at the front end of the machine base, the discharging device is arranged at the side end of the machine base, the discharging device comprises a discharging pipe, a heat dissipation opening, a discharging end opening, a cutter and a material guide cover, the material guide cover comprises a protective cover, a rotating groove, a sliding groove, a cooling device and a material scraping block, the cooling device comprises a supporting base, a water inlet, a fixing base, a contactblock, a closed water pipe and an elastic rod, and the closed water pipe comprises a pipe body, a water retaining block, a water passing groove, a reset spring and a water retaining plate. Accordingto the equipment, the protective cover is mounted at the side end of the cutter, so that water flow can distribution into the contact block, plastic attached to the cutter face can make contact with the water flow to be rapidly subjected to cold cutting, and the material scraping block guides down the plastic solidified on the cutter face, so that the smoothness of the cutter face is guaranteed, and the situation that wiredrawing is caused when the plastic in a molten state is cut is avoided.

Description

technical field [0001] The invention relates to the field of injection molding cooling, in particular to a rotary mold injection cooling molding equipment for plastic particles. Background technique [0002] With the development of science and technology, a large number of plastic products in life are produced, and waste plastics are also increasing. The way to deal with waste plastics is recycling. The cutter cuts the molten plastic, and finally the cut plastic falls into the water tank for cooling, so that the waste plastic can be processed into plastic pellets. [0003] Based on the inventors' discovery above, the existing rotary mold injection cooling molding equipment for plastic granules mainly has the following deficiencies, such as: because the plastic agent in the molten state has a certain viscosity, when the cutter carries out the plastic agent When cutting, part of the solution will be attached to the knife surface, so that after the plastic is solidified on the...

[0003] Based on the inventors' discovery above, the existing rotary mold injection cooling molding equipment for plastic granules mainly has the following deficiencies, such as: because the plastic agent in the molten state has a certain viscosity, when the cutter carries out the plastic agent When cutting, part of the solution will be attached to the knife surface, so that after the plastic is solidified on the cutter, because the end face of the cutter is not flat, the cutter will cut the plastic, and there will be wire drawing, resulting in cooling The case of finished plastic particles with hairs
