Vertical shaft type automatic mold opening device of injection molding machine and injection molding machine made of it

Abstract

The invention provides a vertical rotating shaft type automatic die opening device of an injection molding machine. At a place where a fastener handle is connected with an upslope inclined edge, with the continuous operation of a disc, the fastener handle is subjected to an upward push force by the upslope inclined edge, a lifting prevention device limits a die bottom plate and allows no lower die to be lifted, and after the fastener handle walks a certain distance on the upslope inclined edge, the upslope inclined edge can separate an upper die from the lower die completely, so that automatic die opening can be realized in an operation process of the disc, and continuous automatic die opening can be realized in a continuous operation process of the disc. Furthermore, by adopting a die opening executing mechanism in a frame structure or in a metal tube or metal rod type, on the basis that the structural strength is ensured, the material usage and weight can be reduced greatly, and the cost and the practicability are reduced and improved significantly. Moreover, in a practical working process, a frame body bears the die opening executing mechanism and allows the die opening executing mechanism to be close to or far from the disc in a door opening or closing manner by depending on a vertical rotating shaft, the structure is simple and reasonable, and the movement is concise. The invention also provides an injection molding machine.

Description

technical field [0001] The invention relates to the field of injection molding machinery, in particular to a vertical shaft type automatic mold opening device of the injection molding machine and an injection molding machine with the automatic mold opening device. Background technique [0002] The structure of the disc type injection molding machine is known, such as the Chinese utility model patent CN201320005864.3, a kind of shoe sole injection molding equipment, including a blower, a preheating and cooling device, a mold and a supporting plate; the blower includes a goose head structure and a turntable; the preheating and cooling device includes a cooling fan, a heating rod and an airtight chamber, the preheating and cooling device is fixed on the goose head structure, and the heating rod is fixed inside the airtight chamber, so The cooling fan is fixed outside the airtight cavity; the mold is installed on the upper end of the supporting plate, and the supporting plate is...

Problems solved by technology

[0004] In the actual injection molding process of the aforementioned injection molding machine and mold, it is usually necessary to manually use tools such as metal sticks to knock the buckle structure of the mold, and then insert the metal stick etc. into the gap between the upper mold and the lower mold, and press the Pry open the upper mold, and then push it up to fully open the upper mold. This manual mold opening process is time-consuming, laborious, inefficient, poor mold opening quality, and harmful to the mold itself. Moreover, the heated mold will pose a safety threat to people.
