Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a plastic particle mixing device for injection molding machines. Background Art

[0002] Injection molding machine, also known as injection molding machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines can be divided into vertical, horizontal and vertical-horizontal composite types according to the arrangement of the injection device and the clamping device.

[0003] The injection molding machine needs to adjust the injection color, so it is necessary to use a mixing device to mix plastic particles of different colors. Plastics will be attached with moisture during transportation and storage, but the current mixing equipment does not have a structure for preheating the plastic particles when mixing the plastic particles, making it difficult to dry the plastic particles. The wet plastic particles affect the heating and melting speed of the plastic particles by the injection molding machine, reducing the mixing efficiency of the plastic particles. Bubbles may be generated when the water evaporates, reducing the injection molding quality. For this reason, we propose a plastic particle mixing device for an injection molding machine to solve the above problems. Utility Model Content
