Compared with the prior art, the utility model has the advantages that the fixed die can be better limited and fixed by arranging the die positioning groove on the forming rack, and the movable die is fixed by the electric clamping block (because the pier head die is generally formed by connecting the movable part with the fixed part through the spring, after the hollow tube is clamped by the movable die and the fixed die, the central tube on the pier part is inserted into the hollow tube, and the mop simultaneously extrudes the movable part, so that the contact positions of the end part of the hollow tube and the movable part and the fixed part form the pier head, in the pier head die, the outline of the pier head die of different types can be the same only by adjusting the width of the movable part and correspondingly adjusting the width of the fixed part, therefore, the same die positioning groove 2 can be adopted to position multiple types of pier head dies); the electric clamping block can be lifted through the vertical lifting device, so that the movable die and the fixed die can be in tight fit, and the end part of a hook product is subjected to pier head operation; when the die needs to be replaced, the die can be automatically replaced through the electric clamping block, the rotary table on the mounting plate and the electric clamping jaw at the end part of the connecting arm, so that the labor intensity is reduced, and the replacement efficiency is improved. In addition, the connecting arm of the utility model is a telescopic cylinder which is horizontally arranged, the electric clamping jaw can be stretched, and the electric clamping jaw can be quickly separated from the molding frame, so that the molding frame can be quickly reworked; the mold assembly grabbed by the electric clamping jaw can be placed on the placing plate, and the electric clamping jaw does not need to be electrified for working for a long time; when the mold assembly is replaced, the plurality of vertical telescopic cylinders can synchronously push the bottom plate upwards, so that the mold assembly is pushed out of the mold positioning groove, and the electric clamping jaw is convenient to clamp; when the electric clamping jaw replaces a new mold assembly, the new mold assembly is supported by the bottom plate firstly and then descends along with the bottom plate to enter the mold positioning groove, and the stability of replacement operation is ensured. Therefore, the utility model discloses not only can reduce intensity of labour, still have change efficiency higher, energy-conservation and change the higher advantage of stability.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A simple quick-change device for a forming die at the end part of a hook product of an automobile exhaust system is shown in figures 1 and 2 and comprises a forming rack 1, wherein a die positioning groove 2 for positioning and placing a fixed die is arranged on the forming rack 1; an electric clamping block 3 capable of vertically lifting is arranged right above the die positioning groove 2, and the electric clamping block 3 is used for clamping a moving die; a die change rack 4 is arranged on one side of the forming rack 1, a mounting plate 5 capable of vertically lifting is arranged on the die change rack 4, and a turntable 6 horizontally arranged is rotatably connected to the mounting plate 5; the turntable 6 is connected with a plurality of connecting arms 7 which are distributed circumferentially, and the end parts of the connecting arms 7 are connected with electric clamping jaws 8.

The connecting arm 7 is a telescopic cylinder which is horizontally arranged; a plurality of placing discs 10 corresponding to the electric clamping jaws 8 are arranged on the die changing rack 4 at positions corresponding to the outer sides of the rotary disc 6; the bottom surface of the mold positioning groove 2 is provided with a bottom plate 11, and the bottom surface of the bottom plate 11 is connected with a plurality of vertical telescopic cylinders 12.

The working principle is as follows: when a mould needs to be replaced, the electric clamping block 3 on the forming rack 1 moves the movable mould to the fixed mould in the mould positioning groove 2, and then the electric clamping block 3 is loosened; then, the plurality of vertical telescopic cylinders 12 below the mold positioning groove 2 synchronously act to lift the bottom plate 11, so that the mold assembly consisting of the fixed mold and the movable mold is lifted out of the mold positioning groove 2.

The mounting plate 5 on the die change rack 4 can be lifted; controlling the mounting plate 5 to descend to enable the idle electric clamping jaws 8 to clamp a new mold assembly from the placing plate 10; then, the mounting plate 5 is lifted, a new mold assembly is clamped, and the other electric clamping jaw 8 in an idle state extends through the connecting arm 7 and clamps the mold assembly on the bottom plate 11; the mounting plate 5 is lifted continuously, the electric clamping jaw 8 clamping the mold assembly lifts the mold assembly, and then the connecting arm 7 drives the mold assembly to retract to be close to the outer side of the turntable 6; the turntable 6 rotates (one side of the turntable 6 is provided with a positioning device, so that the turntable 6 can only rotate the included angle between two adjacent electric clamping jaws 8 every time), when the electric clamping jaw 8 clamping the mold assembly is positioned right above the idle placing plate 10, the mounting plate 5 descends, so that the mold assembly is placed on the placing plate 10, and then the electric clamping jaw 8 is loosened; then, the mounting plate 5 is lifted and reset to the height before descending, and the turntable 6 continues to rotate until the electric clamping jaw 8 clamping a new mold assembly is opposite to the molding frame 1; then, the connecting arm 7 drives the electric clamping jaw 8 to extend until a new mold assembly on the electric clamping jaw 8 is positioned above the bottom plate 11; the mounting plate 5 is lowered so that a new mould assembly is placed on the base plate 11 and then the electrically powered jaws 8 are released; subsequently, the electric jaw 8 is shortened and reset, and the mounting plate 5 is also restored to the original height.

A plurality of vertical telescopic cylinders 12 on the mold positioning groove 2 synchronously descend to reset the bottom plate 11, and a fixed mold in a new mold assembly is limited by the mold positioning groove 2; and the electric clamping block 3 extends to clamp and fix the movable die in the new die assembly, so that the die is replaced.
