Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a quick fixing tool for mold cutting. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] When the mold is being processed, it needs to be cut. During the cutting process, in order to maintain the cutting accuracy, fixed tooling will be used to clamp and fix the mold to facilitate the cutting operation.

[0004] The inventor found in his daily work that when clamping, the existing mold processing fixed tooling needs to manually rotate the screw to control the clamping parts to clamp the mold, resulting in slow clamping speed and only being able to clamp the regular mold surface. When faced with special-shaped molds, the clamping parts need to be replaced, resulting in overall inconvenience in use, which in turn leads to the problem that the existing fixed tooling has a slow clamping speed and is not convenient for quickly clamping special-shaped molds. Utility Model Content

Through the above components, the cylinder drives the push block to continue to move, and the push block cooperates with the extrusion piece to clamp the flat mold. When some special-shaped molds need to be clamped, the cylinder can only have a few extrusion pieces fit with the surface of the special-shaped mold. At this time, the air supply component is opened, and the air supply component supplies air to the air cavity. The gas enters the hollow column to push the unclamped extrusion piece, so that the extrusion piece extends out and presses on the special-shaped surface of the mold, thereby achieving clamping. The rotating disk cooperates with the auxiliary component to adjust the angle, thereby improving practicality.

[0007] Preferably, two sliders are fixedly connected to the lower surface of the push block, and a plurality of slide grooves are provided on the surface of the rotating disk. The sliders are slidably connected to the inner walls of the slide grooves. Through the above components, when the cylinder drives the push block to move, the sliders can slide in the slide grooves, thereby improving the stability of the movement of the push block.

[0008] Preferably, the extrusion piece includes a sealing block, which is slidably connected to the inner wall of the hollow column, and a sliding rod is fixedly connected to the surface of the sealing block, and a buffer pad is fixedly connected to one end of the sliding rod. Through the above components, when the gas extrusion piece moves in the hollow column, the sealing block can drive the sliding rod and the buffer pad to move, so that the sliding rod and the buffer pad are squeezed on the surface of the special-shaped mold, and the buffer pad can provide protection.

[0009] Preferably, a return spring is sleeved on the surface of the slide rod, and the two ends of the return spring are respectively fixedly connected to the sealing block and the inner wall of the hollow column.

[0011] Preferably, the surface of the rotating disk is provided with scales, and holes are opened at the outer ring of the rotating disk corresponding to the scales. The inner wall of the workbench is slidably connected with a pull rod, and the pull rod is plugged into the inner wall of the hole. Through the above components, the scales on the surface of the rotating disk are 0 degrees, 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees, respectively.

The cylinder drives the push block and the slider to move in the slide groove on the surface of the rotating disk. The push block drives multiple extrusion pieces to be extruded on the mold with a regular surface to achieve clamping. When clamping a mold with an irregular profile surface, only a few extrusion pieces of the cylinder can fit the surface of the special-shaped mold. At this time, the air supply component is opened, and the air supply component supplies gas to the air cavity. The gas enters the hollow column and pushes the extrusion piece that is not clamped, so that the extrusion piece extends out and presses on the special-shaped surface of the mold, thereby achieving clamping. When it is necessary to adjust the angle, the adjustment and positioning can be achieved by cooperating with the rotating disk through the auxiliary component. By providing the clamping device, it is convenient to quickly clamp regular and irregular special-shaped molds, and the angle can be adjusted for cutting processing. It can process molds of various shapes and sizes, not only limited to regular shapes, which increases the versatility and flexibility of the equipment. There is no need to frequently replace different types of clamping devices to adapt to different molds, saving replacement time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific configuration and function of the clamping device 2 and the auxiliary component 23 will be described in detail below.

[0024] Specifically, the clamping device 2 includes a rotating disk 21, which is rotatably connected to the inner wall of the workbench 1, and two cylinders 22 are fixedly connected to the surface of the rotating disk 21.

A plurality of hollow columns 25 are fixedly connected to the surface of one side of the push block 24, and the plurality of hollow columns 25 are connected to the air cavity 210. An extrusion piece 26 is provided on the inner wall of the hollow column 25, and an air supply component 28 is provided on the surface of the push block 24 and the rotating disk 21, and an auxiliary component 23 is provided on the surface of the workbench 1.

[0025] In this embodiment: the cylinder 22 drives the push block 24 to continue to move, and the push block 24 cooperates with the extrusion piece 26 to clamp the flat mold. When some special-shaped molds need to be clamped, the cylinder 22 can only have a few extrusion pieces 26 that fit the surface of the special-shaped mold. At this time, the air supply component 28 is opened, and the air supply component 28 supplies gas to the air cavity 210. The gas enters the hollow column 25 to push the unclamped extrusion piece 26, so that the extrusion piece 26 extends out and presses on the special-shaped surface of the mold, thereby achieving clamping. The rotating disk 21 cooperates with the auxiliary component 23 to adjust the angle, thereby improving practicality.

[0026] Specifically, two sliders 29 are fixedly connected to the lower surface of the push block 24 , and a plurality of slide grooves are provided on the surface of the rotating disk 21 , and the sliders 29 are slidably connected to the inner walls of the slide grooves.

[0027] In this embodiment, when the cylinder 22 drives the push block 24 to move, the slider 29 can slide in the slide groove, thereby improving the stability of the movement of the push block 24.

[0028] Specifically, the extrusion piece 26 includes a sealing block 263, which is slidably connected to the inner wall of the hollow column 25. A sliding rod 262 is fixedly connected to the surface of the sealing block 263, and a buffer pad 261 is fixedly connected to one end of the sliding rod 262. When the gas extrusion piece 26 moves in the hollow column 25, the sealing block 263 can drive the sliding rod 262 and the buffer pad 261 to move, so that the sliding rod 262 and the buffer pad 261 are squeezed on the surface of the special-shaped mold, and the buffer pad 261 can protect it.

[0029] Specifically, a return spring 264 is sleeved on the surface of the slide rod 262 , and two ends of the return spring 264 are fixedly connected to the sealing block 263 and the inner wall of the hollow column 25 , respectively.

[0030] In this embodiment, the reset spring 264 can drive the sealing block 263 and the sliding rod 262 to reset after the gas is discharged.

[0031] Specifically, the surface of the push block 24 is fixedly connected with an interface 27, and the air supply assembly 28 includes an air injection machine 282, which is fixedly connected to the inner wall of the rotating disk 21. The output end of the air injection machine 282 is fixedly connected to two air supply pipes 281, and the two air supply pipes 281 are respectively fixedly connected to the interface 27 on the surface of the push block 24. The air injection machine 282 can inject or exhaust air into the air cavity 210 on the inner wall of the push block 24 through the air supply pipe 281 and the interface 27.

[0032] Specifically, the surface of the rotating disk 21 is provided with a scale 231 , and a socket 233 is opened at the outer ring of the rotating disk 21 corresponding to the scale 231 . A pull rod 232 is slidably connected to the inner wall of the workbench 1 , and the pull rod 232 is plugged into the inner wall of the socket 233 .

[0033] In this embodiment: the scales 231 on the surface of the rotating disk 21 are 0 degrees, 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees respectively. When the pull rod 232 is inserted into the socket 233 at the corresponding degree, positioning adjustment can be achieved.

[0034] Specifically, a positioning spring 234 is sleeved on the surface of the pull rod 232 , and two ends of the positioning spring 234 are fixedly connected to the pull rod 232 and the surface of the tooling table 1 , respectively.

[0035] In this embodiment: the positioning spring 234 can control the pull rod 232 to return to its original position, thereby improving the binding effect of the pull rod 232.

[0036] Working principle: By setting the clamping device 2, the mold is placed on the rotating disk 21, and the cylinder 22 is turned on. The cylinder 22 drives the push block 24 and the slider 29 to move in the slide groove on the surface of the rotating disk 21. The push block 24 drives multiple extrusion pieces 26 to be squeezed on the mold with a regular surface to achieve clamping. When clamping a mold with an irregular surface, only a few extrusion pieces 26 of the cylinder 22 can fit the surface of the special-shaped mold. At this time, the air supply component 28 is turned on, and the air injection machine 282 injects air into the air cavity 210 on the inner wall of the push block 24 through the air supply pipe 281 and the interface 27. The gas enters the hollow column 25 to push the unclamped extrusion piece 26, so that the extrusion piece 26 extends out and presses on the special-shaped surface of the mold, thereby To achieve clamping, when the angle needs to be adjusted, the auxiliary component 23 is used. When rotation is required, the pull rod 232 is pulled, and the positioning spring 234 is stressed. After the rotating disk 21 is rotated to adjust to the required angle, the pull rod 232 is released, and the positioning spring 234 drives the pull rod 232 to reset and insert it into the corresponding socket 233 to achieve adjustment and positioning. By setting the clamping device 2, it is convenient to quickly clamp regular and irregular special-shaped molds, and the angle can be adjusted for cutting processing. It can process molds of various shapes and sizes, not only limited to regular shapes, which increases the versatility and flexibility of the equipment. There is no need to frequently replace different types of clamping devices 2 to adapt to different molds, saving replacement time.
