Description

Forming die with gaseous ejecting structure Technical Field The utility model relates to the technical field of dies, in particular to a forming die with a gas ejection structure. Background The lamp parts are generally produced by injection molding. Because of the modeling requirement of manufacturers, the demolding angle of the appearance surface of many car lamp parts cannot meet the technical standard, and when the product is demolded, friction with a mold can be generated, scratch marks can be formed on the surface of the product, and therefore the surface quality of the product is affected. Therefore, it is necessary to design a molding die having a gas ejection structure to solve the above-mentioned problems. Disclosure of utility model The utility model aims at overcoming the defects of the prior art and provides a forming die with a gas ejection structure. The technical scheme is that the forming die with the gas ejection structure comprises a fixed die and a movable die, a cavity of a product is formed after the fixed die and the movable die are closed, a gas supply channel is arranged in the fixed die and corresponds to the cavity of the product to be subjected to auxiliary demolding, and the gas supply channel is communicated with an external gas source. The fixed die comprises a fixed die holder and a fixed die core embedded in the fixed die holder, wherein the air supply channel consists of a first channel arranged on the fixed die holder and a second channel arranged on the fixed die core, an outlet of the first channel is arranged corresponding to an inlet of the second channel, and an outlet of the second channel extends to a die cavity where the product needs auxiliary demoulding. The fixed die holder comprises a fixed die seat, a fixed die core, a first channel, a second channel and a second channel, wherein the fixed die seat is arranged in the middle of the fixed die seat, the fixed die core is embedded in the mounting groove, the first channel comprises a first air inlet transversely extending into the fixed die seat from one side of the fixed die seat and a second air guide hole vertically communicated with the first air guide hole from the bottom of the mounting groove, the second channel comprises a first air blowing hole vertically arranged in the fixed die core, one end of the first air blowing hole is communicated with the second air blowing hole, the other end of the second air blowing hole obliquely extends to a die cavity where a product needs to be demoulded, and an outlet of the second air guide hole is arranged corresponding to an inlet of the first air blowing hole.
