Embodiment approach

[0031] As an embodiment of the present invention, the front and rear sides of the lower mold 4 are fixedly provided with permanent magnetic chucks 41, and the front end of the permanent magnetic chuck 41 is provided with a suction cup handle 42 for controlling its holding or release. The iron block 21 matching the permanent magnetic chuck 41 is provided on the side wall of the upper mold 2 directly above the 41 . Since the elastic member 73 and the stop block 65 are clamped, their self-locking force is relatively limited, and still requires a lot of energy consumption for mold clamping. Therefore, in the process of mold closing, through the force of the permanent magnetic chuck 41 and the iron block 21 The setting can make the permanent magnetic chuck 41 suck the iron block 21 by pulling the suction cup handle 42 after the mold closing is completed, and reduce the energy consumption of the mold clamping by magnetic force; when the mold is opened, pull the suction cup handle 42 ...

Abstract

The invention relates to the technical field of molds, in particular to an automatic mold opening and closing mechanism. The automatic mold opening and closing mechanism comprises an upper mold, a lower mold and a bottom plate, wherein the lower mold is fixedly arranged on the bottom plate, a plurality of guide columns are arranged between the upper mold and the lower mold, the upper end of the upper mold communicates with an oil cylinder through a piston rod, and the upper mold can move up and down along the guide columns under the action of the oil cylinder to do mold opening or mold closingaction; containing boxes with openings in the upper ends are fixedly arranged on the left side and the right side of the lower mold, limiting blocks are fixedly arranged on the front side wall and the rear side wall in each containing box, and arc-shaped surfaces which are arched inwards are arranged in the middles of the limiting blocks; and two elastic pieces which are symmetrically arranged front and back are fixedly arranged on the side wall of the upper mold right above the containing boxes, and arc-shaped extrusion parts matched with the limiting blocks are arranged in the middles of the elastic pieces. According to the automatic mold opening and closing mechanism, the elastic pieces, the limiting blocks, a mold locking block, a first clamping block, an iron block and a permanent magnet chuck are arranged so that the self-locking of multiple positions can be realized while mold closing is carried out, and the energy consumption of mold locking is reduced.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automatic mold opening and closing mechanism. Background technique [0002] The die-casting machine is mainly composed of various parts such as mold clamping mechanism, injection mechanism, hydraulic system and electric control system. In addition, the die-casting machine also has parts and machine bases, other devices, auxiliary devices and other parts. Among them, the opening and closing mechanism is to drive the die-casting mold to close and open. When the mold is closed, the opening and closing mechanism is required. There is enough force to lock the mold to ensure that the parting surface of the mold will not expand during the injection filling process. [0003] Chinese patent (notification number: CN2008201250625) discloses a mold clamping device for a two-platen machine, including a moving platen, a tie rod, a fixed platen, a tie rod nut, a tie rod pressure plate, a mold...
