The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-4, an embodiment of the present invention is shown: a mechanism capable of automatically demoulding comprises a lower die sleeve 2, wherein a demoulding mechanism 3 is arranged in the lower die sleeve 2; the demoulding mechanism 3 comprises a plurality of pushing pieces 38 with the same mechanism, and the pushing pieces 38 are linked with a linkage piece 37; horizontally sliding the link member 37 by the pushing member 38 in the lower die case 2 to slide upward or downward; the end of the pushing element 38 away from the link 37 is further provided with a thimble 310, and the thimble 310 pushes the workpiece to be separated from the lower die case 2 by the sliding of the link 37.

In summary, compared with the prior art, the device utilizes the plurality of pushing pieces 38 to control the movement of the linkage piece 37, so that the linkage piece 37 is powerful and more uniform in movement when lifted, a hundred percent success rate is provided for demolding operation, and the production efficiency is greatly improved. Therefore, the device does not need to be directly contacted with the workpiece by hands during demoulding, and the problem of personnel scalding caused by the high temperature of the workpiece is further reduced.

Preferably, the number of the pushing members 38 is two, and the pushing members 38 are symmetrically arranged on two sides of the lower die sleeve 2, so that the two pushing members 38 can smoothly slide on two sides of the lower die sleeve 2 to apply force to two ends of the link member 37, and the link member 37 can smoothly and reliably slide up and down, so that power from the pushing members 38 can be smoothly transmitted to the link member 37.

In order to further ensure the smooth movement of the linkage piece 37 and the pushing piece 38, and in particular, to avoid the problem of deviation of the pushing piece 38 and the linkage piece 37 during power transmission, the pushing piece 38 is provided with a guide surface 36, and the guide surface 36 is matched with a sliding surface arranged on the linkage piece 37 to realize smooth sliding of the linkage piece 37, and the sliding direction of the linkage piece 37 on the pushing piece 38 is limited due to the fact that the sliding surface on the linkage piece 37 is inserted into the guide surface 36.

In addition, the guide surface 36 arranged obliquely moves along with the pushing member 38, so as to drive the linkage member 37 to move up and down smoothly, and particularly, the problem that the linkage member 37 swings on a horizontal plane can be avoided. The safety of the sliding action is ensured, and the linkage piece 37 is not separated from the lower die sleeve 2; the driving unit 39 may be a cylinder.

Because one side of the lower die sleeve 2 is provided with a driving part 39 for driving the pushing part 38 to slide, a power source can be provided for the movement of the pushing part 38, and meanwhile, the other side of the lower die sleeve 2 is provided with a synchronization mechanism 311 for keeping the two pushing parts 38 to move synchronously, the synchronism of the driving part 39 in controlling the two pushing parts 38 to work can be ensured.

Further, the synchronizing mechanism 311 includes a rack 31 mounted on the pushing member 38 and a gear 30 engaged with the rack 31, and the rack 31 and the gear 30 are driven to move in a linked manner by the operation of the pushing member 38.

Through the scheme, the two pushing pieces 38 can move synchronously, and particularly, when the driving part 39 works, the two pushing pieces 38 can be ensured to extend or shorten synchronously, wherein the number of the gears 30 is equal to that of the pushing pieces 38 with the same number as that of the racks 31, the two gears 30 are connected through the synchronizing shaft 33, the gears 30 are installed at two ends of the synchronizing shaft 33 through the combined bearings 34, and the two gears 30 are fixed at two ends of the synchronizing shaft 33 through the check rings 35; the combined bearing 34 is a bearing in which a needle roller and a thrust ball are combined. And the retainer ring 35 is an a-type elastic retainer ring; the synchronizing shaft 33 is fixed to the lower die case 2 by a bearing housing 32.

Because the lower die sleeve 2 and the upper die sleeve 1 which is arranged move oppositely, an upper die 4 which is arranged on the upper die sleeve 1 and a lower die 5 which is arranged on the lower die sleeve 2 move oppositely, so that a workpiece is formed. Through the mode, the two die sleeves are matched with the upper die 4 and the lower die 5, so that the workpiece is formed better.

The working principle of the utility model is as follows: oil pipes are used for connecting oil inlet and oil outlet of the two driving parts 39, and the two driving parts 39 are controlled to push the pushing part 38 to move back and forth, so that the linkage part 37 is driven to do up and down lifting actions, the thimble 310 is lifted finally, and the workpiece is demoulded;

the driving part 39 is controlled to drive the pushing piece 38 to contract, and the thimble 310 is retracted. The linkage of the period driving part 39 with the rack 31 and the gear 30 ensures the synchronism of the lifting action again, thereby realizing the automatic demoulding function.

That is, when the driving part 39 pulls the pushing part 38 back to move backward, the inclined plane is lowered, the linkage part 37 moves downward, the thimble 310 descends, a worker hooks a workpiece, blows air to clean the die, and finally places the next workpiece blank to enter the next workpiece production.

Further, the driving portion 39 is connected to the pushing member 38 via a t-bolt, and drives the link member 37 to move up and down in the lower die case 2.

Wherein, the length and width of the upper die 4 and the lower die 5 are the same, and both are 700mm by 160 mm; the size of the link 37 is 500mm by 40 mm;

based on the above, the die space included in the mechanism can reach 160mmX700mm, so that the requirement of large size of the workpiece can be easily solved, namely, the size of the workpiece for one-time stamping provided by the upper die 4 and the lower die 5 is larger; and the oversized jacking space 40mmX550mm also provides support for the follow-up demolding jacking process, the jacking range is enlarged, the number of thimbles is increased, and support is provided for a multi-pass structure of a workpiece.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
