Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to a clamping device for mold processing. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. During the mold processing process, a clamping device is often required to clamp and fix the mold.

[0003] The Chinese patent "A clamping and fixing device for mold processing" authorization announcement number "CN219945354U" pulls the positioning rod downward through the pull ring to move the positioning rod out of the positioning hole at the bottom end of the support rod, thereby canceling the limit fixation of the support rod, and then rotates the support rod one hundred and eighty degrees to release the positioning rod. At this time, the elastic force of the spring can make the positioning rod reinsert into the corresponding positioning hole, and the support rod can be re-limited and fixed, so that the positions of the two clamping plates on the support rod can be interchanged, and then the handwheel plate is turned to remove the threaded column from the support rod, and the worn clamping plate can be removed from the support rod, thereby realizing the disassembly and replacement of the clamping plate and improving the overall maintainability.

[0004] Although the clamping plate can be disassembled and replaced in the above application, the staff needs to perform multiple steps to complete the replacement and disassembly of the clamping plate. The operation steps are relatively cumbersome, time-consuming and labor-intensive.

[0005] Therefore, a clamping device for mold processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a clamping device for mold processing in order to solve the above problems, thereby improving the problem that the workers need to perform multiple steps to complete the replacement and removal of the clamping plate, and the operation steps are relatively cumbersome, time-consuming and labor-intensive.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a clamping device for mold processing, comprising: a base, both sides of the top end of the base are fixedly connected to a mounting plate, one side of the mounting plate is fixedly connected to an electric push rod, one end of the electric push rod passes through the mounting plate and is fixedly connected to a fixed block, the other side of the fixed block is installed with a clamping plate, and the inner wall of the fixed block is provided with a disassembly mechanism; wherein, the disassembly mechanism includes a round rod slidably connected to the inner wall of the fixed block, the top of the fixed block is provided with a mounting groove, one side of the fixed block is provided with a fixing groove, the mounting groove is connected to the fixing groove, one end of the round rod passes through the inner side of the mounting groove and is fixedly connected to a limiting plate, the surface of the round rod is fixedly connected to a circular ring, one end of the circular ring is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the fixed block.

[0008] Preferably, the disassembly mechanism further comprises a first airbag fixedly connected to the inner wall of the fixing groove, a second airbag fixedly connected to the inner bottom wall of the fixing groove, and a connecting tube communicating between the first and second airbags. When the splint fixing rod automatically falls into the fixing groove, the limit plate automatically resets and squeezes the first airbag, which facilitates automatically squeezing the gas in the first airbag into the second airbag, causing the second airbag to expand. This facilitates wrapping and securing the middle and lower ends of the splint fixing rod, thereby increasing the stability of the splint fixing rod within the fixing groove.

[0009] Preferably, one side of the fixed block is slidably connected to a slider, one side of the slider is fixedly connected to a limiting rod, the other end of the round rod extends through the fixed block, and a limiting hole is defined on the surface of the round rod. The limiting rod and the limiting hole facilitate limiting the position of the round rod, ensuring the stability of the round rod in pushing the limiting plate, and improving the stability of the limiting plate against the surface of the clamping plate.

[0010] Preferably, the bottom end of the limit plate is fixedly connected with a contact pad, which is a rubber component, so as to increase the stability of the limit plate bottom end when it is pressed against the upper end of the clamping plate fixing rod surface.

[0011] Preferably, the surface of the contact pad is provided with grooves distributed in equal rows, and the grooves are provided in an oblique and reverse direction, which is beneficial to increase the friction between the surface of the contact pad and the surface of the clamping plate fixing rod.

[0012] Preferably, the outer surface of the second airbag is in contact with the inner wall of the fixing groove, and the inner surface of the second airbag is concave in an arc shape, which is conducive to better contact between the inner surface of the second airbag and the surface of the splint fixing rod.

[0013] Preferably, the bottom end of the limiting rod is curved into a spherical shape, which is conducive to making the limiting rod enter the limiting hole better.

[0014] The beneficial effects of the utility model are:

[0015] 1. The disassembly mechanism is set up. When installing the splint, the fixing rod of the splint moves in the installation groove, which is conducive to the fixing rod of the splint pushing the limit plate to automatically release the blockage of the fixing groove. At the same time, when the fixing rod of the splint coincides with the fixing groove, the fixing rod will automatically fall into the fixing groove to limit the splint in the horizontal direction. Under the action of the spring, it is conducive to automatically resetting the limit plate to press against the upper end of the surface of the fixing rod of the splint, so as to quickly complete the installation of the splint. When disassembling the splint, it is only necessary to pull the round rod to drive the limit plate to release the blockage of the fixing groove to remove the splint. The operation steps are simple, saving time and effort.

[0016] 2. When the fixing rod of the splint automatically falls into the fixing groove, the limiting plate automatically resets and squeezes the first airbag, which is conducive to automatically squeezing the gas in the first airbag into the second airbag to expand the second airbag, which is conducive to wrapping and fixing the middle part and the lower end of the surface of the splint fixing rod, thereby increasing the stability of the splint fixing rod in the fixing groove;

[0017] 3. When the limit plate is pressed against the surface of the splint fixing rod, under the action of the limit rod and the limit hole, it is beneficial to limit the round rod, ensure the stability of the round rod pushing the limit plate, and provide improved stability of the limit plate pressed against the surface of the splint fixing plate.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-5 As shown, a clamping device for mold processing includes: a base 1, both sides of the top of the base 1 are fixedly connected to a mounting plate 2, one side of the mounting plate 2 is fixedly connected to an electric push rod 3, one end of the electric push rod 3 passes through the mounting plate 2 and is fixedly connected to a fixed block 4, the other side of the fixed block 4 is installed with a clamping plate 5, and the inner wall of the fixed block 4 is provided with a disassembly mechanism 6; wherein, the disassembly mechanism 6 includes a round rod 61 slidably connected to the inner wall of the fixed block 4, the top of the fixed block 4 is provided with a mounting groove 62, one side of the fixed block 4 is provided with a fixing groove 614, the mounting groove 62 is connected to the fixing groove 614, one end of the round rod 61 passes through the inner side of the mounting groove 62 and is fixedly connected to a limiting plate 63, the surface of the round rod 61 is fixedly connected to a circular ring 64, one end of the circular ring 64 is fixedly connected to a spring 65, and the other end of the spring 65 is fixedly connected to the inner wall of the fixed block 4.

[0026] The overall shape of the limiting plate 63 is "L" shaped. The inner wall of the fixing block 4 is provided with a sliding groove that matches the ring 64. The splint 5 includes a fixing rod and a clamping plate. When installing the splint 5, the fixing rod of the splint 5 is put into the upper opening of the mounting groove 62. The overall shape of the mounting groove 62 is "L" shaped. At this time, the surface of the fixing rod contacts the inner wall of the mounting groove 62, and the fixing rod of the splint 5 is pulled along the path of the mounting groove 62 to move. During the movement, the fixing rod will push the limiting plate 63 to move, so that the limiting plate 63 The round rod 61 and the circular ring 64 are driven to move synchronously, and the spring 65 is compressed, thereby releasing the blockage of the fixing groove 614. At this time, the fixing rod of the splint 5 and the fixing groove 614 are in the same vertical plane. Under the action of the splint 5's own gravity, the fixing rod of the splint 5 will automatically enter the fixing groove 614. At this time, the squeezing of the limit plate 63 is released, and under the action of the spring 65, the limit plate 63 will automatically reset, blocking the top of the fixing groove 614 again, and pressing against the upper surface of the fixing rod of the splint 5.

[0027] After the splint 5 is installed, the electric push rod 3 can be started to drive the fixing block 4 and the splint 5 to move synchronously to fix the mold.

[0028] like Figure 3 、 Figure 4 and Figure 5As shown, the disassembly mechanism 6 also includes a first airbag 66 fixedly connected to the inner wall of the fixing groove 614, a second airbag 67 fixedly connected to the inner bottom wall of the fixing groove 614, and a connecting pipe 68 is connected between the first airbag 66 and the second airbag 67.

[0029] When the device is in the initial state, under the action of the spring 65, the round rod 61 pushes the limit plate 63 to block the opening of the fixing groove 614 and squeeze the first airbag 66. After being squeezed, the gas in the first airbag 66 enters the second airbag 67 through the connecting tube 68, and the second airbag 67 expands.

[0030] When the fixing rod of the splint 5 pushes the limiting plate 63 to move, the limiting plate 63 will release the squeezing of the first airbag 66. At this time, the gas in the second airbag 67 will flow back into the first airbag 66. When the fixing rod of the splint 5 is located on the inner side of the fixing groove 614, the limiting plate 63 squeezes the first airbag 66 again, allowing the gas to enter the second airbag 67 again, causing the second airbag 67 to expand and wrap and fix the middle part and the lower end of the surface of the fixing rod of the splint 5.

[0031] like Figure 3 and Figure 4 As shown, a slider 69 is slidably connected to one side of the fixed block 4, and a limit rod 610 is fixedly connected to one side of the slider 69. The other end of the round rod 61 passes through the fixed block 4, and a limit hole 611 is provided on the surface of the round rod 61. The bottom end of the limit rod 610 is curved into a spherical shape.

[0032] The limiting rod 610 itself has a certain weight. When the limiting plate 63 blocks the opening of the fixing groove 614, the bottom end of the limiting rod 610 and the limiting hole 611 are on the same vertical plane. At this time, the limiting rod 610 will enter the limiting hole 611 under the action of its own gravity, completing the limitation of the round rod 61.

[0033] When the splint 5 needs to be disassembled, the limit rod 610 is pulled upward and the round rod 61 is pulled away from the fixed block 4, thereby driving the limit plate 63 to move synchronously to release the limit on the upper end of the surface of the fixed rod of the splint 5, and at the same time release the squeezing of the first airbag 66. At this time, the gas in the second airbag 67 flows back to the first airbag 66 again, thereby releasing the fixation of the surface of the fixed rod of the splint 5, and the splint 5 can be taken out.

[0034] like Figure 3 、 Figure 4 and Figure 5 As shown, the bottom end of the limit plate 63 is fixedly connected to a contact pad 612, which is a rubber component. The surface of the contact pad 612 is provided with grooves 613 distributed in equal rows, and the grooves 613 are opened in an inclined and reverse direction. When the fixing rod of the clamping plate 5 is placed in the fixing groove 614, the surface of the contact pad 612 contacts the upper surface of the fixing rod, as shown in FIG. Figure 3 and Figure 4 As shown, the outer surface of the second airbag 67 is in contact with the inner wall of the fixing groove 614, and the inner surface of the second airbag 67 is concave and arc-shaped. When the fixing rod of the splint 5 enters the fixing groove 614, the surface of the fixing rod contacts the inner surface of the second airbag 67.

[0035] When the present invention is in use, when installing the splint 5, the fixing rod of the splint 5 is put into the upper opening of the mounting groove 62, and the fixing rod of the splint 5 is pulled to move along the path of the mounting groove 62. During the movement, the fixing rod pushes the limiting plate 63 so that the limiting plate 63 drives the round rod 61 and the ring 64 to move synchronously, and the spring 65 is compressed, thereby releasing the blockage of the fixing groove 614 and releasing the squeezing of the first airbag 66. When the fixing rod of the splint 5 and the fixing groove 614 are in the same vertical plane, the fixing rod of the splint 5 will automatically enter In the fixing groove 614, at this time, under the action of the spring 65, the limit plate 63 will automatically reset, block the top of the fixing groove 614 again, and press against the upper end of the surface of the fixing rod of the splint 5. At the same time, the limit plate 63 squeezes the first airbag 66 again, allowing the gas to enter the second airbag 67 again. The second airbag 67 expands to wrap and fix the middle part and the lower end of the surface of the fixing rod of the splint 5. At the same time, the limit rod 610 will enter the limit hole 611 under the action of its own gravity, completing the limitation of the round rod 61.

[0036] When the splint 5 needs to be disassembled, the limit rod 610 is pulled upward and the round rod 61 is pulled away from the fixed block 4, thereby driving the limit plate 63 to move synchronously to release the limit on the upper end of the surface of the fixed rod of the splint 5, and at the same time release the squeezing of the first airbag 66. At this time, the gas in the second airbag 67 flows back to the first airbag 66 again, thereby releasing the fixation of the surface of the fixed rod of the splint 5, and the splint 5 can be taken out.

[0037] It should be noted that the electric push rod 3 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the electric push rod 3 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
