Embodiment

[0059] The quick clamping device for the upper mold of this embodiment is mainly used in production equipment that needs to clamp and replace the mold, such as a bending machine, so as to realize efficient and accurate clamping and replacement of the mold. In this embodiment, taking a bending machine as an example, the structure of the clamping device, as well as its clamping and dismounting methods are described in detail, as follows.

[0060] The upper mold quick clamping device mainly includes an upper mold base 100 and an upper mold 200 used in conjunction with each other, wherein the upper mold base 100 is used to connect the slider of the bending machine, and the upper mold 200 is detachably installed on the upper mold base 100 , used to bend the workpiece on the upper mold. According to the shape of the workpiece of the bending machine, the upper mold 200 used also changes accordingly. The focus of this embodiment is the connection form of the upper mold 200 and the uppe...

Abstract

The invention discloses an upper mold quick clamping device and application thereof and an application method, and belongs to the technical field of mold design. The device comprises an upper mold base, an upper mold, a hose base, a thimble and a hose; a mold mounting hole for mounting the upper mold is formed in the bottom of the upper mold base; the hose base is fixed on the side surface of theupper mold base, and a pipe groove is formed in the side surface thereof opposite to the upper mold base; the hose is positioned in the pipe groove; a thimble hole opposite to the pipe groove is formed in the side surface of the upper mold base, and communicates with the mold mounting hole; the thimble is arranged in the thimble hole, and the end thereof near the mold mounting hole is a positioning end; and a clamping groove cooperating with the positioning end of the thimble is formed in the side surface of the upper mold. The clamping device skillfully adopts a structural form of hydraulic force driving expansion of the hose to drive the thimble to clamp the upper mold to quickly realize clamping of the upper mold, achieves a two-way self-positioning effect to achieve higher clamping precision, greatly simplifies the structure, and is few in part, simple in clamping, low in cost and reliable in clamping.

Description

technical field [0001] The invention belongs to the technical field of mold design, and more specifically relates to a fast clamping device for an upper mold and its application and use method. Background technique [0002] Mold is a variety of molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. It mainly realizes the shape of the item through the change of the physical state of the formed material. processing. [0003] The bending machine is a device that uses a bending die to perform bending operations on the workpiece. It drives the die installed on the slider to move up and down through the up and down movement of the oil cylinder, and squeezes the lower die installed on the workbench to realize For the bending of the workpiece, the processing of different workpieces requires the replacement of different bending upper dies, so e...
