Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to an adaptive pressure clamping device for mold parts. Background Art

[0002] During the processing of mold parts, a clamping device is required to tighten the mold parts to prevent the mold parts from moving during the processing, resulting in defective products. An adaptive pressure clamping device is currently available, including a base, a threaded rod and two claws, the threaded rod is rotatably connected to the base, one claw is fixedly connected to the surface of the base, and the other claw is threadedly connected to the threaded rod, and the claw is composed of a plurality of arc blocks, a large arc block is rotatably connected to two slightly smaller arc blocks, the slightly smaller arc block is rotatably connected to two even smaller arc blocks, and the even smaller arc block is rotatably connected to two semicircular blocks.

[0003] When using the clamping device to clamp the mold part, the staff first presses one side of the mold part against the fixed jaw, and then rotates the threaded rod to drive the movable jaw to move. The movable jaw will fit against the mold part, and the semicircular block will contact the outer wall of the mold part. Since the outer wall of the mold part is uneven, and the semicircular block and the arc block, and the arc blocks are all rotationally connected, the semicircular block and the arc block will rotate to make the semicircular block fit the outer wall of the mold part as much as possible, thereby applying the clamping force to the mold part more evenly, so that the clamping device can adapt to the shape of the mold part and apply adaptive uniform pressure to the mold.

[0004] The patent with the publication number CN217168139U discloses a rotatable universal clamp. Through the clever structural design, the left and right clamp heads can form any suitable contact surface with the parts, effectively solving the problem that many special-shaped parts cannot be clamped, and the situation that many non-standard parts cannot be fixed during processing, and the situation that multi-directional clamping cannot be achieved during part processing. It greatly improves the processing quality, reduces manual intervention in clamping and contacting parts, saves time and effort, greatly reduces labor costs, and improves the degree of automation.

[0005] Although the above device solves the problem that the traditional bench vise will cause the flat surface of the part to be damaged, the following problems still exist:

[0006] When in use, the existing adaptive clamping device cannot fix the upper and lower surfaces of the mold parts. During the contact between the clamping claws and the mold parts, the mold parts may become skewed, causing the surface of the mold parts to tilt, which in turn will cause the processing accuracy of the mold parts to decrease. It may also cause uneven contact between the tool and the mold parts, resulting in uneven tool wear. In severe cases, the tool may break or fly out, causing harm to the operator. Summary of the invention

[0007] In view of the deficiencies of the prior art, the utility model provides a mold part self-adaptive pressure clamping device, which makes it difficult for the mold part to be skewed when clamped.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 4 As shown, a mold part adaptive pressure clamping device includes a base 1, one side of the base 1 is fixedly connected to a fixed rod 2, the surface of the fixed rod 2 is fixedly connected to a sliding rod 3, the surface of the fixed rod 2 is slidably connected to a sliding plate 4, the bottom surface of the sliding plate 4 is provided with a sliding groove 5 corresponding to the position of the sliding rod 3, the side of the sliding plate 4 away from the base 1 is fixedly connected to a connecting block 6, the top of the connecting block 6 is detachably connected to a fixed plate 7, the end of the fixed plate 7 away from the connecting block 6 is provided with a threaded groove 21, the inner thread of the threaded groove 21 is connected to a threaded rod 8, the bottom end of the threaded rod 8 is fixedly connected to a pressing plate 9, the surface of the sliding plate 4 is fixedly connected to another pressing plate 9, the two pressing plates 9 match in shape and position, and the top of the threaded rod 8 is fixedly connected to a moving block 20.

[0023] like Figure 1 As shown, the mold part adaptive pressure clamping device in the utility model is similar to the existing clamping device structure, such as a rotatable universal clamp disclosed in the patent with publication number CN217168139U. The main improvement of the utility model is that it makes it difficult for the mold part to be skewed when clamped, such as Figures 1 to 4As shown, when a mold part adaptive pressure clamping device in the utility model is in use, when the mold part needs to be clamped, the mold part is first placed on the pressure plate 9 on the sliding plate 4, and then the movable block 20 is rotated to drive the threaded rod 8 to rotate, and the threaded rod 8 will drive the pressure plate 9 to descend and contact the mold part. At this time, the two pressure plates 9 will clamp the mold part to keep the mold part straight. Then the staff uses the clamping device to fix the two sides of the mold part with claws. At this time, the mold part cannot be skewed. After the claws clamp the mold part, the movable block 20 is rotated to separate the pressure plate 9 from the mold part, and then the sliding plate 4 is slid to separate the sliding plate 4 and the fixed plate 7 from the mold part to avoid affecting the processing of the mold part.

[0024] By arranging a pressure plate 9 on the sliding plate 4 and the threaded rod 8, and utilizing the mutual cooperation between the threaded rod 8 and the pressure plate 9, the mold parts are provided with vertical clamping, thereby ensuring that when the clamping claws are clamped on both sides of the mold parts, the mold parts will not be skewed, thereby improving the stability of the mold parts, and then improving the processing accuracy of the mold parts, enabling uniform contact between the tool and the mold parts, and avoiding the occurrence of safety accidents.

[0025] like Figure 2 and Figure 3 As shown, the fixing plate 7 is fixedly connected to a connecting column 10 on one side close to the connecting block 6, a connecting groove 11 corresponding to the position of the connecting column 10 is provided on the surface of the connecting block 6, a limiting block 12 is fixedly connected to the side of the connecting block 6 away from the base 1, a limiting groove 13 is provided on one side of the limiting block 12, a limiting rod 14 is connected to the inner thread of the limiting groove 13, one end of the limiting rod 14 is in contact with the outer wall of the connecting column 10, and the other end of the limiting rod 14 is fixedly connected to a rotating plate 15.

[0026] Specifically, when it is necessary to clamp a larger mold part, the rotating plate 15 can be rotated, the limiting rod 14 will be separated from the connecting column 10, and then the fixed plate 7 can be lifted until the mold part can be placed between the two pressure plates 9, and then the rotating plate 15 is rotated again to make the limiting rod 14 abut against the outer wall of the connecting column 10 to provide fixation for the connecting column 10; through this arrangement, clamping of mold parts of different sizes can be achieved, thereby improving the overall applicability of the clamping device.

[0027] like Figure 2 and Figure 3 As shown, one end of the side wall of the sliding plate 4 away from the base 1 is fixedly connected to a positioning block 16, a positioning groove 17 is provided in the positioning block 16, a positioning rod 18 is threadedly connected to the positioning groove 17, one end of the positioning rod 18 is in contact with the outer wall of the fixing rod 2, and the other end of the positioning rod 18 is fixedly connected to a knob 19.

[0028] Specifically, after the pressure plate 9 clamps the mold part, the sliding plate 4 is pushed so that the mold part is located in the center of the claw, and then the knob 19 is rotated so that the positioning rod 18 is against the outer wall of the fixing rod 2. At this time, the sliding plate 4 cannot slide, thereby providing fixation for the mold part. When the claw completes clamping, the knob 19 is rotated again to cancel the fixation of the sliding plate 4, so that the sliding plate 4 can be separated from the mold part.

[0029] like Figure 2 and Figure 3 As shown, the outer wall of the knob 19 is provided with anti-slip grooves.

[0030] Specifically, the anti-slip pattern can bring convenience to rotating the knob 19 and prevent the staff from slipping.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the adjacent surfaces of the two pressing plates 9 are both fixedly connected with an elastic layer 22 , and a plurality of elastic blocks 23 are fixedly connected with the surface of the elastic layer 22 .

[0032] Specifically, the function of the elastic layer 22 is to prevent the pressure plate 9 from crushing the mold parts when clamping the mold parts. When the pressure plate 9 clamps the mold parts, the elastic layer 22 will deform, thereby absorbing part of the pressure to prevent damage to the mold parts due to excessive pressure. The elastic block 23 can further enhance the elasticity of the elastic layer 22, making the pressure plate 9 more stable when clamping the mold parts.

[0033] like Figure 1 and Figure 2 As shown, a baffle plate 24 is slidably connected to one side of the fixing rod 2 , a bolt 25 is connected to one side of the baffle plate 24 , and the bolt 25 is threadedly connected to the fixing rod 2 .

[0034] Specifically, when the sliding plate 4 needs to be removed, the bolts 25 are removed using a screwdriver, and then the baffle 24 is removed, and the sliding plate 4 can be slid out along the slide rod 3; the baffle 24 can provide a limit for the sliding plate 4 to prevent the sliding plate 4 from being lost.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
