A slide rail type automatic mold opening device for a disc type injection molding machine and the injection molding machine

Abstract

The invention provides a sliding rail type automatic die opening device of a disc type injection molding machine. The sliding rail type automatic die opening device comprises a frame, a die opening execution mechanism and a lifting prevention device. The die opening execution mechanism is provided with an upslope bevel edge, and the upslope bevel edge is gradually heightened in the rotation direction of a disc. Thus, in the actual use process of the device, at the joint of a buckle handle and the upslope bevel edge, along with continuous running of the disc, the buckle handle bears upward pushing force of the upslope bevel edge, a die bottom plate is limited by the lifting prevention device, and therefore a lower die cannot be lifted up; and after the buckle handle walks on the upslope bevel edge for a certain distance, an upper die and the lower die are completely separated by the upslope bevel edge, automatic die opening can be achieved in the running process of the disc, and continuous automatic die opening can be achieved in the continuous running process of the disc. In addition, by means of bearing of a sliding rail on the frame, the whole die opening execution mechanism can be close to or far away from the disc by means of guiding and carrying of the sliding rail, and die opening on all the dies or die opening stopping is carried out in good time. The invention further provides the injection molding machine.

Description

technical field [0001] The invention relates to the field of injection molding machinery, in particular to a slide rail type automatic mold opening device for a disc type 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 pla...

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.
