Abstract

The invention discloses a positioning column structure suitable for injection moulding. The positioning column structure is characterized by comprising a center block and multiple ribs integrally formed with the center block, wherein the ribs have a first kind of end parts and a second kind of end parts; the first kind of end parts of the ribs are connected with the center block so that the center block and the ribs form a whole; and the second kind of end parts of the ribs are separated from the center block. In the invention, the second kind of end parts of the ribs in the existing positioning column structure suitable for injection moulding are subjected to complete smoothing, and the corner angles on the existing second kind of end parts are eliminated, so that the molten plastic can quickly fill each part of the positioning column structure suitable for injection moulding along the second kind of end parts after complete smoothing, thus the shortcomings of air bubbles and the like are avoided, the yield of injection moulding products is greatly improved, and the structural strength of the product is perfectly guaranteed.

Description

technical field [0001] The invention relates to a positioning column structure suitable for injection molding, in particular to a positioning column structure suitable for injection molding used on a plastic touch screen frame mold, and belongs to the field of plastic mold design. Background technique [0002] When manufacturing the touch screen frame, it is necessary to use a touch screen frame mold. The structure of the touch screen frame mold sometimes needs to use a positioning column structure. The positioning column structure in the prior art usually has edges and corners, and such angled ends often hinder the molten plastic. Filling the cavity sufficiently and quickly is not suitable for injection molding, which often leads to low yield of injection molded products. In addition, this structure is difficult to ensure the structural strength of the product. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the pr...
