Description
Technical Field
The utility model relates to an exhaust insert pin structure.
Background
In the injection molding process, if residual gas in the cavity cannot be discharged in time, great negative effects are generated on the quality of products and the injection molding cycle. For example, if the gas is not exhausted in time, the gas in the cavity is compressed and reaches a high temperature immediately, and the high-temperature gas contacts with the product, so that the product is partially carbonized or burnt. Therefore, venting is a critical issue to be addressed in injection molds.
At present, one common method for solving the problem of exhaust during injection molding is to add an insert pin at a deep bone position or a column position of a product to achieve the purpose of exhaust. Adopt the inlaying mode to exhaust, utilize the clearance between mold insert and the mould to exhaust, the exhaust of whole mold insert face is not completely even, and causes the phenomenon that the product runs the mantle easily. In order to solve the problem of exhaust of the insert surface, the breathable steel is directly made into the insert. This alleviates the problem of uniform venting, but the service life of the vented steel insert becomes a major problem. The insert pin made of the breathable steel has low strength and is easy to break and block. In addition, the exhaust steel is very expensive, which results in a high cost of use of such inserts.

2. The lower part of the exhaust surface is of a porous topological structure, the exhaust structure is connected with the air entraining structure through a topological reinforcing structure, the exhaust pressure is small, the exhaust is smooth, the timely discharge of gas in the cavity is ensured, and a better exhaust effect is achieved.
3. Be equipped with additional strengthening, overall structure intensity is high, and the difficult fracture that takes place of use has long service life, has reduced use cost.
4. The exhaust area is whole face exhaust, and non-inlay piece formula exhaust mode compares in traditional inlay piece formula exhaust mode, and exhaust area is bigger, and it is even to exhaust, has improved injection moulding product quality.
5. The exhaust structure is characterized by short micropore stroke, difficult blockage and convenient cleaning and maintenance. The reinforcing ring and the topological reinforcing structure ensure the capability of the exhaust insert pin for resisting injection molding pressure.
