Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a material blocking device for injection molding. Background Art

[0002] The injection molding process is a very mature modern process for product modeling production. It injects thermoplastics or thermosetting materials into the injection molding machine, and then injects them into the plastic molding mold. A product with a specific shape and size is formed in the plastic molding mold. When the injection molding machine is working, the discharge port of the injection molding machine is connected to the glue inlet on the fixed mold to achieve glue injection. When the type of raw material of the injection molding machine is changed, such as replacing white raw material with black raw material, the injection molding machine needs to be separated from the mold, and then the injection molding machine is started to squeeze out the residual plastic raw material in the injection molding machine. The hot plastic raw material is easy to splash to both sides and accidentally injure the staff.

[0003] A Chinese patent document with the existing application number CN202023211906.8 records a material blocking device for injection molding. When the device is in use, the injection tube of the injection molding machine is first pulled out of the injection port of the mold, and then the two motors are started. The two motors rotate in opposite directions, driving the rotating shaft and the baffle to flip outward ninety degrees, so that the baffle is perpendicular to the table top of the workbench, and then the injection tube of the injection molding machine is moved between the two baffles to squeeze out the remaining plastic raw material. The splashing plastic raw material will be blocked by the baffles on both sides to play a splash-proof role, thereby preventing the plastic raw material from splashing onto the staff on both sides, thereby improving safety in use. The plastic raw material blocked by the baffle falls into the collection liner of the collection box, which is convenient for collecting the plastic raw materials, facilitating subsequent cleaning, and improving ease of use. The disadvantage is that the baffles are only distributed on the front and back sides of the collection box. Although the extruded raw materials are prevented from accidentally injuring the surrounding personnel, the splashed raw materials are easy to fall into the glue inlet of the fixed mold, causing pollution to the fixed mold, thereby affecting the quality of the processed products after switching the raw materials. In addition, the collection box for collecting waste raw materials is not easy to take out, and it is not easy for workers to process the waste raw materials inside. If the processing is not timely, the collection box will be full of waste materials, affecting subsequent use. Utility Model Content
