[0002] In the production process of integrated nano-frames, injection molding is generally used. However, due to high speed and high pressure, the die-cast parts on the product sidewalls are easily deformed and damaged, resulting in aluminum chipping; aluminum parts and mold inserts are chipped on the sidewalls; and the product appearance is scratched, leading to the FPC cutting off the assembly line in the later process. Therefore, a front mold structure was designed to prevent aluminum chipping from the die-cast parts. Utility Model Content

[0003] The purpose of this utility model is to provide a front mold structure that prevents aluminum scraping from the front mold die casting, which addresses the shortcomings of the existing technology. This front mold structure is novel in design and simple in structure, effectively preventing aluminum scraping from the front mold die casting, solving the problem of local FPC wire groove damage and burrs, and improving product quality.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A front mold structure for preventing aluminum from being scraped off a die-cast part includes a front mold, a front mold cavity arranged in a concave shape at the upper end of the front mold, and a plurality of mold cavity inserts installed at the upper end of the periphery of the front mold cavity. An inclined oblique pull insert is installed at the upper end of one end edge of the front mold cavity, and a corresponding matching oblique pull spring is installed at the upper end of the oblique pull insert.

[0006] The front mold has convexly arranged front mold tubes at its four upper corners.

[0007] The front mold has several horizontally arranged front mold flow channels located on the upper surface opposite to the front mold cavity.

[0008] The inclined pull spring is installed in the spring receiving hole provided at the upper end of the inclined pull insert.

[0009] The beneficial effects of this utility model are as follows: The front mold structure for preventing aluminum scraping from die-cast parts according to this utility model includes a front mold, a front mold cavity arranged concavely at the upper end of the front mold, and several mold cavity inserts installed at the upper ends of the four edges of the front mold cavity. An inclined oblique pull insert is installed at the upper end of one edge of the front mold cavity, and a corresponding matching oblique pull spring is installed at the upper end of the oblique pull insert. By installing an inclined oblique pull insert at the upper end of one edge of the front mold cavity, and a corresponding matching oblique pull spring is installed at the upper end of the oblique pull insert, this utility model effectively prevents aluminum scraping from die-cast parts, solves the problem of local FPC wire groove scratches and burrs, and improves product quality. Therefore, this utility model has the advantages of novel design, simple structure, effective prevention of aluminum scraping from die-cast parts, solving the problem of local FPC wire groove scratches and burrs, and improving product quality.
