Description

Technical Field

[0001] The invention relates to the technical field of mold processing auxiliary equipment, and in particular to a storage mechanism capable of mechanical automatic reset. Background Art

[0002] Generally speaking, after the mold is completed and before it is taken off the machine, a storage block needs to be placed between the upper and lower mold frames before it is taken off the machine for storage or maintenance. The first is to prevent the elastic components from being in a working state for a long time and fatigue failure. The second is to prevent the guide components from eating too much and making it difficult to open the mold offline.

[0003] Commonly used storage blocks include: rigid storage blocks, resin storage blocks, nitrogen spring storage, and rigid storage blocks + sensor detection.

[0004] However, in the actual work process of stamping plants and mold factories, there are cases of missed storage during stamping every year. When missed storage blocks are used, it may cause devastating damage to the mold, have a huge impact on the accuracy of the press, and even threaten the life safety of the operator;

[0005] When using resin as a storage block, although it is much safer than a rigid storage block, when a leakage event occurs, the resin storage block will be crushed. It takes a long time to remake it after crushing. The waiting time will lead to huge economic losses. If a large number of spare parts are made in advance, it will cause a waste of warehouse space and economic occupation. Secondly, the storage state of the resin storage block is prone to deformation, which will greatly limit the machine tools that require a high degree of flatness in the mold storage state.

[0006] When using nitrogen springs for storage, nitrogen cylinder springs are expensive and take up a lot of space, which greatly increases the cost burden of the enterprise;

[0007] The form of rigid storage block + sensor detection is relatively reliable, but sensor signal failure occurs from time to time, and there are also major safety hazards. Summary of the invention

[0008] In order to overcome the defects of the prior art, the present invention provides a storage mechanism that can be mechanically reset automatically. The storage block and the bottom block are hingedly connected, and are connected to each other at the far end through an elastic device on one side of the hinge. A through hole is correspondingly arranged on the other side, and a connecting push rod is arranged in the through hole. When in use, as long as the mold is opened, the storage block will automatically mechanically flip and reset under the action of the elastic device, thereby effectively avoiding the problem of missing the storage block.

[0009] The technical solution to achieve the above purpose is:

[0010] The present invention provides a mechanically automatically reset storage mechanism, comprising a storage block and a bottom block located between an upper mold frame and a lower mold frame, wherein the bottom block is fixedly mounted on the top of the lower mold frame, the storage block is located directly above the bottom block, and the storage block has an opposite hinged side and an open side, wherein

[0012] A first fixing block is installed on the opening side, the first fixing block is provided with a first through hole running through from top to bottom, a matching first top block is provided in the first through hole, a second fixing block connected to the bottom block is provided below the first fixing block, the second fixing block is provided with a second through hole, the second through hole is located directly below the first through hole, and the diameter of the second through hole is not greater than the diameter of the first through hole, a matching second top block is provided in the second through hole, the second top block can be moved up and down to extend into the first through hole, a second waist-shaped hole arranged up and down is provided on the side of the second fixing block away from the bottom block, a second limiting block connected to the second top block is provided in the second waist-shaped hole, and the second limiting block is pushed upward in the second waist-shaped hole to drive the second top block to move upward and extend into the first through hole, thereby pushing the first top block to move upward, so that the first top block partially protrudes out of the storage block.

[0013] Furthermore, a first waist-shaped hole arranged up and down is provided on a side of the first fixing block away from the opening side, and a first limiting block connected to the first top block is provided in the first waist-shaped hole to prevent the first top block from falling off from the first through hole after the storage block is flipped over.

[0014] Furthermore, a hinge device is provided corresponding to the hinged part between the hinged side and the bottom block, which is strong and durable, and improves the wear resistance of the hinged part between the storage block and the bottom block, thereby increasing the service life of the mechanism.

[0015] Furthermore, the first fixing device and the second fixing device are both hexagon socket screws, and are detachably mounted on the storage block and the bottom block respectively, so as to facilitate the disassembly and assembly of the first fixing device and the second fixing device, and also facilitate the replacement of the elastic device.

[0016] Furthermore, nuts are sleeved on the first fixing device and the second fixing device, and the nuts are respectively close to the storage block and the bottom block to prevent the hexagon socket screws from loosening and falling off after long-term work.

[0017] Furthermore, the elastic device is a spring, which is easy to obtain locally, has low cost, and is easy to use and replace.

[0018] Furthermore, the first limiting block and the second limiting block are both hexagon socket screws, which are easy to obtain, easy to install and use, and low in cost.

[0019] Furthermore, the second limiting block protrudes outwardly from the second fixing block along one end away from the bottom block, so as to facilitate the movement of the second limiting block.

[0020] Beneficial effect: Compared with the prior art, the difference of the present invention lies in that the storage mechanism with mechanical automatic reset provided by the present invention comprises a storage block and a bottom block, the hinged side of the storage block is hingedly connected to the bottom block, and a first fixing device and a second fixing device with elastic connection are correspondingly arranged away from the hinge, a first fixing block is arranged on the opening side of the storage block, the first fixing block is provided with a first through hole and a first top block, a second fixing block connected to the bottom block is correspondingly arranged below the first fixing block, and a second through hole and a second top block are correspondingly arranged, and the second fixing block is also provided with a waist-shaped hole and a second limiting block. After the mold is completed and before being removed from the machine, the storage block is flipped to the top of the bottom block, the second limiting block is pushed upwards, and the second top block extends into the first through hole and The first top block is ejected, and under the pulling force of the elastic device on the hinged side and the connection between the second top block on the open side and the first through hole, the storage block, the first top block and the second top block all maintain their inherent shapes. When the machine is removed from the machine, the upper mold frame is pressed onto the storage block, and the second top block is pressed down to its original position by the first top block. When the mold is opened again, due to the lack of connection between the second top block and the first fixed block, the storage block will automatically flip and reset under the retraction pulling force of the elastic device. Relying on purely mechanical automatic reset and flipping, the control is more reliable and the risk of missing the storage block is effectively avoided. At the same time, the mechanism is very simple to process and operate, and is easy to obtain materials, maintain and repair, which greatly reduces the cost of the enterprise and has a very wide range of applicability.
