Description

Technical Field

[0001] The present application relates to the field of injection molded part cutting, and in particular, to a device for cutting a gate of an injection molded part. Background Art

[0002] The gate, also known as the feed port, refers to a section of the channel from the branch channel to the mold cavity. It is the smallest and shortest part of the pouring system. In metal casting, it refers to the entrance and channel for the molten metal to enter the mold during pouring. It often refers to the pouring system. Its function is to use the constricted flow surface to accelerate the feeding. The high shear rate can make the feeding fluidity good. The heating effect of viscous heating also has the effect of increasing the material temperature and reducing the viscosity. After the molding is completed, the gate is first solidified and sealed. It has the function of preventing the feed from flowing back and avoiding the mold cavity pressure from dropping too fast to cause the molded product to shrink and sag. After molding, it is convenient to cut off to separate the runner system and the molded part. For example, the Chinese patent application number CN202021023509.5 is an injection molding inner injection gate cutting assembly, including a support plate, a fixed plate is fixedly connected to the upper surface of the support plate, a slide groove is opened on one side of the fixed plate, a slider is slidably connected to the inside of the slide groove, a cutting knife is provided on one side of the moving plate, and a moving rod is fixedly connected to the other side of the moving plate.
