Die head accumulated material automatic-clearing mechanism during movement of plastic injection opening of blow molding machine

Abstract

The invention discloses a die head accumulated material automatic-clearing mechanism during movement of a plastic injection opening of a blow molding machine. The die head accumulated material automatic-clearing mechanism comprises a supporting seat, a first telescopic air cylinder, a second telescopic air cylinder and a servo motor. The first telescopic air cylinder and a first fixed board are fixed to the inner wall of the supporting seat through screws; the first fixed board is arranged above the first telescopic air cylinder; a fixed seat is fixed to the output end of the first telescopicair cylinder through screws; a fixed box is disposed on the inner side of the fixed seat; a second fixed board is integrally connected to the bottom end of the fixed box; the second telescopic air cylinder is disposed on the outer surface of the second fixed board in a penetrating mode; the bottom end of the second telescopic air cylinder is connected and fixed to the inner wall of the fixed seatthrough screws; the output end of the second telescopic air cylinder is connected and fixed to the inner wall of the fixed box through screws; and a first chamber is formed in the inner side of the fixed box. An annular clearing structure is adopted, and thus a die head can be cleared conveniently, rapidly and automatically.

Description

technical field [0001] The invention relates to the technical field of the plastic hollow blow molding industry, in particular to an automatic cleaning mechanism for mold accumulation based on the movement of the injection port of a blow molding machine. Background technique [0002] The die head of the blow molding machine is a device that discharges the rubber evenly. When the blow molding machine is working, the rubber is discharged evenly through the die, and then the rubber is squeezed into the mold cavity through two templates, and the rubber is squeezed into the mold cavity by the blowing unit. Blow air into the mold cavity to shape the compound. [0003] When the die head is discharging, due to the factors of the feeding time and the material of the rubber material, there will be material accumulation at the glue outlet of the die head. If the material accumulation is not cleaned up in time, it will cause the surface of the blown product to appear. Unfavorable condi...
