Machining mechanism for products with textured surface

Abstract

The invention discloses a machining mechanism of a product with a texturing surface. The machining mechanism comprises a mold; a cavity for accommodating an injection product is formed in the mold; the inner surface of the cavity is the texturing surface; the mold at least includes a third slide block, a fourth slide block and a fifth slide block forming the cavity, wherein the third slide block and the fourth slide block are arranged side by side; a vertical fourth arc surface is arranged on one side of the fourth slide block; the third slide block is connected with the edge of the fourth arc surface; the fifth slide block is positioned on the upper surfaces of third slide block and the fourth slide block, and is connected with the same; a third arc surface is arranged in the connecting place between the fifth slide block and the fourth slide block; correspondingly, the edge line, near one side of the third slide block, of the fourth arc surface is staggered from the edge line, near one side of the third slide block, of a second butt joint arc surface; and or, the edge of the third slide block spans the edge line, near one side of the third slide block, of the second butt joint arc surface. The machining mechanism has the characteristics of simple and reasonable structure and high product pass percent.

Description

technical field [0001] The invention relates to a processing mechanism for products with etched surfaces. Background technique [0002] Existing injection molding products 1, as attached figure 1 As shown, the surface of the injection molded product 1 is an appearance etched surface, the two adjacent sides of the injection molded product 1 are side straight surfaces with a surface flatness of 0 degrees, and the top of the injection molded product 1 is provided with a first docking arc surface R1, a second butt arc surface R2 is provided between two adjacent side surfaces of the injection molded product 1 . The traditional way of making this injection molded product 1 is to set the first slide block 2 and the second slide block 3 respectively on the adjacent two side straight body surfaces of the injection molded product 1, see figure 2 As shown, the boundary surface or boundary line between the first slider 2 and the second slider 3 is set on the left side of the second b...

AI Technical Summary

Problems solved by technology

When ejecting the mold, since there is no slope at the left starting line of the second butt arc surface R2, that is, at the position of the parting surface, it is very easy to cause the injection molded product 1 to be strained at the parting surface, thereby affecting the product. Pass rate
