Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a texture mold for preventing products from being damaged. Background Art

[0002] There is currently a mold processing technology that forms mold texture by etching inside the mold. When the mold is formed, these etchings will cause concave and convex textures on the surface of the molded part, thereby covering the shrinkage, glue lines, parting surfaces, and slider shape discontinuity marks on the product, while increasing the surface strength and appearance texture of the product.

[0003] For example, Chinese patent CN2 1 9667296U discloses an injection mold, which includes an upper mold frame, a lower mold frame, a support seat, an ejector pin, a guide pin, and an ejector pin plate located in a second vertical channel and connected to the lower end of the ejector pin. The upper mold plate and the lower mold plate form a mold cavity, and the guide pin ensures that the upper and lower mold plates remain stable when the mold is opened and closed.

[0004] However, for some molds with textured lines, their side walls are no longer smooth, and some molded parts have grooves in multiple directions. If the upper and lower molds are directly opened and closed, the molded parts or the lines on the surface of the molded parts may be damaged, thereby affecting the molding quality.

[0005] Based on this, the utility model designs a texturing mold which prevents product damage to solve the above problem. Utility Model Content
