Description

Technical Field

[0001] This utility model relates to the field of injection molding tool technology, specifically a device for cutting sprue material in injection molded products. Background Technology

[0002] In injection molding, workpieces typically have sprues, which are the joints between the mold frame and the part formed during the casting process. Also known as "gates," they are the inlets and outlets for the flow of molten plastic. The molten plastic flows into the mold cavity through these inlets and outlets. After the injection molded part is formed, the plastic at the inlets and outlets also solidifies, forming the sprue. The method for handling sprues is to cut the part off the sprue.

[0003] A utility model patent with Chinese patent publication number CN212331716U discloses a device for cutting sprue material from injection molded products. This device places a circular injection molded part above the discharge port of a positioning table, suspending the sprue material within the ring above the discharge port. A power source pressurizes the device, causing a pressure plate to drive a cutter to cut the sprue material from the ring. The cut sprue material falls through the discharge port, thus achieving automatic sprue removal. This device automates the removal of sprue material from circular injection molded parts, reducing manual labor intensity, ensuring consistent product quality, facilitating standardized production, and improving production efficiency through automation. Research on existing technologies and the aforementioned patent reveals that the cutter positions in existing technologies for removing sprue material are relatively fixed, lacking flexibility and applicability. Therefore, this utility model proposes a device for cutting sprue material from injection molded products. Utility Model Content
