Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machines, and particularly relates to a mold clamp for an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a kind of equipment widely used in the plastic products processing industry. Its main function is to heat and melt thermoplastic or thermosetting plastic raw materials, and then inject them into the mold through high pressure, and form plastic products of various shapes after cooling and solidification. The existing injection molding machine mold clamp places the mold to be used in the specified position, drives the motor to run, and drives the motor to drive the clamping module to approach the mold to be used to quickly clamp the mold. However, in actual use, due to the relatively single clamping direction of the mold, the mold may be displaced under the action of external force.
