[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting and stamping. The mould has a specific contour or inner cavity shape. The contour shape with a cutting edge can separate the blank according to the contour shape.

[0003] When replacing the mold on the existing punch press, the mold transfer arm needs to be repeatedly disassembled and assembled, which makes the process of replacing the mold cumbersome and inconvenient;

[0004] The reason for this problem is that when the current punching machine needs to replace the mold with a different inner cavity shape, it is necessary to install the mold shifting arm on the side wall of the punching machine through multiple sets of screws, and then slide the mold on the mold shifting arm for disassembly and replacement. After replacement, the mold shifting arm needs to be removed again, so that each time the mold is replaced, the mold shifting arm needs to be repeatedly disassembled and assembled, resulting in a cumbersome and inconvenient process of replacing the mold. In view of the shortcomings of the existing technology, we propose a device for producing metal molds that is easy to replace to solve the above problems. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application provides a device for facilitating replacement of metal molds, thereby solving the problem that when replacing the mold on the punch press, the mold shifting arm needs to be repeatedly disassembled and assembled, resulting in a cumbersome and inconvenient process of replacing the mold.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model embodiment discloses a device for facilitating replacement of production metal molds.

[0025] According to the attached Figure 1-4 As shown, a device for facilitating replacement of metal molds in production includes a mold shifting arm 1 arranged on the side wall of a punch press, the side wall of the mold shifting arm 1 is provided with a supporting structure 2, and the supporting structure 2 includes a π-shaped member 201, an electric telescopic rod 203 and a fixed rod 204;

[0026] The specific functions between the punch press and the die transfer arm 1 refer to the open punch press model JH21.

[0027] The π-shaped part 201 is fixedly connected to the side wall of the punch press, the die shifting arm 1 is rotatably connected to the inside of the π-shaped part 201, the electric telescopic rod 203 is rotatably connected between the punch press and the die shifting arm 1, the fixed rod 204 penetrates the side wall of the π-shaped part 201, and the fixed rod 204 is inserted into the side wall of the die shifting arm 1. By setting a supporting structure 2 between the die shifting arm 1 and the punch press, and by rotatably connecting the die shifting arm 1 to the π-shaped part 201 of the supporting structure 2, the die shifting arm 1 can be supported and used by driving the electric telescopic rod 203, thereby avoiding the current situation where the cumbersome process of disassembling and assembling the die shifting arm 1 on the punch press each time the mold is replaced.

[0028] The inner wall of the π-shaped member 201 is fixedly connected with a shaft rod 2011 , and the mold transfer arm 1 is rotatably connected to the outer peripheral wall of the shaft rod 2011 .

[0029] The bottom of the mold shifting arm 1 is fixedly connected to a support plate 202, and the bottom of the support plate 202 is fixedly connected to a hinge 2021. The electric telescopic rod 203 is rotatably connected to the inside of the hinge 2021. The electric telescopic rod 203 is driven to push the two groups of mold shifting arms 1 to rotate upward at the same time until the mold shifting arm 1 rotates to correspond to the level of the top surface of the punch press, and the mold can be slid on the mold shifting arm 1 for disassembly and assembly.

[0030] A circular groove 101 is provided on the side wall of the mold shifting arm 1, and a fixing rod 204 is inserted into the inside of the circular groove 101. The cross-section of the fixing rod 204 at the opposite end is an inclined surface. When the mold shifting arm 1 rotates upward, the two groups of fixing rods 204 are squeezed on both sides until the circular groove 101 on the mold shifting arm 1 rotates to the corresponding position of the fixing rod 204. The fixing rod 204 is reset by the pulling force of the spring 206. At this time, the fixing rod 204 will be inserted into the circular groove 101 to further fix the mold shifting arm 1.

[0031] The end of the fixed rod 204 is fixedly connected to a movable rod 205, and the movable rod 205 is movably connected to the inside of the π-shaped part 201. By pulling the movable rod 205 outward, the fixed rod 204 can be driven to shrink inside the π-shaped part 201. At this time, the electric telescopic rod 203 can drive the mold moving arm 1 to rotate downward for storage.

[0032] A spring 206 is sleeved on the outer peripheral wall of the movable rod 205 , and two ends of the spring 206 are fixedly connected to the side wall of the fixed rod 204 and the inside of the π-shaped member 201 respectively.

[0033] A slot 2051 is provided at the top of the movable rod 205, and a clamping plate 207 is rotatably connected to the side wall of the π-shaped member 201. The clamping plate 207 is clamped inside the slot 2051. By rotating the clamping plate 207 downward so that it is clamped in the slot 2051 at the top of the movable rod 205, the movable rod 205 can be locked.

[0034] When the utility model is in use, the clamping plate 207 is first rotated upward to make it slide out of the clamping groove 2051, and then the two groups of die shifting arms 1 are pushed to rotate and support upward at the same time through the driving of the electric telescopic rod 203. At the same time, the die shifting arm 1 will squeeze the two sides of the two groups of fixed rods 204 until the die shifting arm 1 is rotated to correspond to the top surface of the punch press. At this time, the circular groove 101 on the die shifting arm 1 just corresponds to the position of the fixed rod 204. The fixed rod 204 will be reset by the pulling force of the spring 206, and will be plugged into the circular groove 101 to further fix the die shifting arm 1. Finally, the clamp on the punch press is moved out of the mold, and the mold can be slid on the die shifting arm 1 for disassembly and replacement.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
