Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

Referring to fig. 1 to 3, the present embodiment provides a lift mechanism of a microseismic compaction molding machine, which includes a lift driving device 1, a beam 2, a lift bracket 3 and a plurality of lift rods 6.

The lifting driving device 1 comprises an oil cylinder which is vertically arranged upwards and comprises a cylinder body 12, a base 14, an upper cover 11, a piston 15 and a piston 15 rod 13, wherein an oil inlet 122 and an oil outlet 121 are formed in one side of the cylinder body 12. The piston 15 and the rod 13 are fixedly connected with the middle position of the cross beam 2. And the beam 2 is horizontally arranged.

The stripping supports 3 are arranged in two numbers and are symmetrically arranged at the left end and the right end of the cross beam 2. The front ends of the two stripping supports 3 are fixedly connected through a synchronizing rod 8. Ejector pins 6 are vertically arranged on the stripping supports 3 at intervals, as an implementation mode, 2 ejector pins 6 are respectively arranged on each stripping support, and the ejector pins 6 on the two stripping supports 3 are arranged in a bilateral symmetry mode. Specifically, a position-adjustable pressure plate 7 is mounted on the stripping bracket 3, and the ejector rod 6 is vertically mounted on the pressure plate 7. Be provided with the mounting hole on the drawing of patterns support 3, be provided with the bar hole on the clamp plate 7, clamp plate 7 passes through the bolt fastening in the mounting hole.

Guide rods 4 are respectively vertically arranged on two sides of an upper cover 11 of the oil cylinder, and through holes matched with the guide rods 4 are formed in the cross beam 2; the upper ends of the two guide rods 4 are connected with guide rod 4 seats.

The working principle of the embodiment is as follows: when oil enters the oil cylinder, the rod 13 of the piston 15 rises, and the stripping bracket 3 is driven to rise by the cross beam 2, so that the stripping action is finished; when the oil cylinder is out of oil, the piston 15 rod 13 descends, and the stripping support 3 resets. In the process, the guide rod 4 is perfectly matched with the cross beam 2, so that the stripping bracket 3 can keep moving in the vertical direction.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
