Abstract
The utility model discloses an easy-to-clean anti-blocking blow pin structure for blow molding, comprising: a blow pin body, the outer end of which is connected to an external blow molding air pump through a first interface, the inner end of which is inserted into a blow molding machine and extends into a blow pin hole, the inner end of the blow pin hole is connected to a blow molding cavity, and the outer end is connected to an expansion cavity, the size of the expansion cavity is larger than that of the blow pin hole, the blow pin body is connected to a second interface through a side discharge channel, and the second interface is connected to an external blow fan; a driving mechanism is used to drive the blow pin body to move into or out of the blow molding cavity. The utility model can solve the problem of oil accumulation in the blow pin hole and the end of the blow pin during the blow molding process under the use process of the conventional blow pin structure, which causes the blow pin to be blocked, the internal blockage to occur during exhaust, the quality of the batch products to be poor, and the blow molding efficiency to be reduced due to the inconvenience of blow pin cleaning.
