Description

Overflow structure is prevented to street lamp casing aluminium die casting die

Technical Field

The utility model relates to the technical field of dies, in particular to an overflow preventing structure of an aluminum die casting die for a street lamp shell.

Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts. The processing of the appearance of the article is realized mainly by changing the physical state of the formed material. The term "industrial mother" is used.

Most of the existing positioning modes of the die adopt the mode of making tiger mouth positioning at four corners of front and rear die cores, but when processing the product with larger volume of the lamp housing of the road lamp, the following 2 problems easily occur due to the fact that the die is larger and the die locking force required by the die is larger:

1. the tiger mouth is easy to damage and fail;

2. during injection, the sizing material is easy to splash out to cause potential safety hazard.
