Embodiment 1

[0041] Please refer to figure 1 and figure 2 , the EVA hot and cold molding machine provided in this embodiment includes a thermoforming machine 10 for heating the mould, and a cold molding machine 20 for cooling the mould. The thermoforming machine 10 includes a rotating base 110 capable of 360° intermittent rotation. There are n stations on the base 110, n≥2, each station is provided with a heating element 130 and a first hydraulic cylinder 140 for driving the heating element 130 to reciprocate in the vertical direction, and the center of the rotating base 110 is provided with The first mold pushing mechanism 120 , the movable end of the first mold pushing mechanism 120 is aligned with the position where the mold is placed on the first station, and is used to push the heated mold to the cold forming machine 20 . The cold forming machine 20 includes a coolant tank 210 and a lift mechanism 220 arranged in the coolant tank 210. The lift mechanism 220 is close to the first sta...

Embodiment 2

[0043] Please refer to figure 1 and figure 2 , the present embodiment is further provided with a third mold pushing mechanism on the lifting mechanism 220, the third mold pushing mechanism is perpendicular to the moving direction of the second mold pushing mechanism 230, and the third mold pushing mechanism is used to lift the cooled mold from the lifting mechanism 220 roll out. The moving directions of the second mold pushing mechanism 230 and the third mold pushing mechanism are vertical, and the stretching time of the movable ends is one in front and one in back without interfering with each other.

Embodiment 3

[0045] Please refer to figure 1 and figure 2, the EVA hot and cold forming machine provided in this embodiment also includes a workbench 30, the EVA cold and hot forming machine includes a thermoforming machine 10, a cold forming machine 20 and a workbench 30, and the mold to be heated is pushed from the workbench to the lifting mechanism 220, the mold after cooling is pushed out from the lifting mechanism 220 to the workbench 230, as long as one worker stands next to the fixed workbench during the entire cold and hot forming process, the operation of multiple stations can be completed without walking around, and the working environment is relatively safe. Personal danger is avoided.

Abstract

The invention discloses an EVA cold / hot forming machine. The machine comprises a hot forming machine and a cold forming machine; the hot forming machine includes a rotating base capable of intermittently rotating by 360 degrees; n stations are annularly arranged on the rotating base; a first mold pushing mechanism is arranged in the center of the rotating base; a movable end of the first mold pushing mechanism is aligned to a mold placing position on the first station; each station is provided with a heating part and a first hydraulic cylinder; the cold forming machine includes a cooling liquid box and a lifting mechanism arranged in the cooling liquid box; the lifting mechanism is near the first station, and is provided with a second mold pushing mechanism; and the moving directions of the second mold pushing mechanism and the first mold pushing mechanism are positioned on the same straight line or in parallel for pushing molds to be heated on the lifting mechanism to the heating parts. The EVA cold / hot forming machine is simple and compact in structure, is combined only by the cold forming machine and the hot forming machine, and can finish work of multiple stations only by one operator standing in one station.

Description

technical field [0001] The invention relates to plastic molding equipment, in particular to an EVA cold and hot molding machine and a mold exchange method thereof. Background technique [0002] EVA is ethylene-vinyl acetate copolymer. EVA has a wide range of applications, especially in the shoe industry, where it is used in the soles and interior materials of mid-to-high-end travel shoes, mountaineering shoes, slippers, and sandals. [0003] The traditional EVA molding process consists of a group of multiple stations lined up. A group of machines is divided into multiple hot stations and multiple cold stations. The operator pulls out the hot mold by hand and puts it into the cold station. Mold, this kind of process makes the operator walk back and forth on the edge of the machine continuously, pushing and pushing the mold out continuously. When working, the work efficiency is low, the cycle time is long, and a lot of manpower, material resources and energy are wasted. cost...
