Description

Technical Field

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

[0002] A mold is a tool used to make molded objects. This tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the object's shape by changing the physical state of the molded material.

[0003] The mold manufacturing process includes a series of complex machining processes from blank to finished product. The mold needs to be clamped during the molding process to prevent it from shifting during the processing. However, in the prior art, when the plastic mold is being processed, the clamping device cannot automatically fix the mold for the workpiece to be clamped. The operator needs to manually adjust the mold to fix it, which wastes a lot of manpower and time, increases the labor intensity of the operator, and reduces the processing efficiency of the product.

[0004] The existing patent (publication number: CN215880835U) discloses a clamping device for precision mold processing, which uses the gravity of the mold itself to make the gravity plate and the tooth plate A descend. During the descending process, the auxiliary gear and the sleeve will cause a positive rotation effect. While rotating, the sliding connection between the slide shaft and the sliding shaft causes the slide shaft, the moving block and the fixed block to move inward, thereby achieving the effect of automatically positioning the mold.

[0005] In view of the above problems, the existing patent provides a solution, but in the process of fixing the mold, the bottom wall of the mold will slide on the surface of the gravity plate, that is, the bottom wall of the mold and the gravity plate will rub against each other. When the bottom wall of the mold contains dust, the friction between the bottom wall of the mold and the gravity plate is large, which can easily cause wear of the bottom wall of the mold. As the number of uses increases, the bottom wall of the mold wears severely, even to the point of wear and damage.

[0006] Therefore, a clamping device for precision mold processing is proposed. Summary of the invention

[0007] The utility model aims to provide a clamping device for precision mold processing, which can solve the problem that the bottom wall of the mold is damaged due to severe wear.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for precision mold processing, including a workbench, characterized in that: a socket is provided on the top wall of the workbench, a support plate is fixedly installed in the socket, a movable plate is slidably installed in the socket, balls are evenly and movably embedded on the top wall of the movable plate, a through hole matching with the ball is provided on the top wall of the support plate, and a first motor is fixedly installed on the inner bottom wall of the workbench, a one-way threaded rod is fixedly installed on the output end of the first motor, the one-way threaded rod passes through the movable plate, and the movable plate is threadedly connected to the one-way threaded rod; two mutually matching limit rods are provided on the top wall of the workbench, and mutually matching sliding grooves are symmetrically provided on the side walls on adjacent sides of the two limit rods; and a fixing mechanism is provided on the limit rod.

[0009] Preferably, a mounting frame is fixedly mounted on the top wall of the workbench, a bidirectional threaded rod is rotatably mounted on the mounting frame, two mounting blocks are symmetrically threadedly mounted on the bidirectional threaded rod, the limit rod is fixedly mounted on the mounting block, and a second motor with an output end fixedly connected to the bidirectional threaded rod is provided on the workbench.

[0010] Preferably, a mounting hole is opened on the side wall of the slide groove, a stopper is slidably installed in the mounting hole, a threaded column penetrating the mounting hole is horizontally fixedly installed on the side wall of the stopper, and a fastening nut is threadedly installed on the threaded column.

[0011] First, adjust the number of revolutions of the second motor according to the size of the mold, thereby adjusting the distance between the two limit rods, then prevent the mold from being located between the two slide grooves, and then move the stop block position along the mounting hole. After the stop block moves to the specified position, fix the stop block by turning the fastening nut, thereby limiting the staying position of the mold moving along the slide groove.

[0012] The moving direction of the mold is limited by the side wall of the slide groove, and then the first motor is started. At this time, the output end of the first motor drives the one-way threaded rod to rotate, so that the movable plate can move up until the ball passes through the through hole and lifts the mold. At this time, the staff can manually push the mold to move along the slide groove and limit the mold position by the side wall of the slide groove. In this process, the rolling friction force on the mold is small, which can protect the mold, reduce the degree of wear of the mold, and play a role in protecting the mold.

[0013] Preferably, air holes are evenly opened on the bottom wall of the slide groove, fan blades are provided on the one-way threaded rod, and a delay mechanism cooperating with the fan blades is provided on the one-way threaded rod.

[0014] Preferably, the delay mechanism comprises a smooth rod fixedly mounted on a one-way threaded rod, and a spring cooperating with the movable plate is fixedly mounted on the bottom wall of the support plate.

[0015] Preferably, the surface of the spring is coated with lubricating oil.

[0016] During the rotation of the first motor, the one-way threaded rod drives the fan blades to rotate. At this time, the fan blades blow air upward, so that the gas can pass through the gap between the ball and the movable plate, and then move upward through the through hole and the air hole to directly impact the surface of the mold, thereby cleaning the bottom wall of the mold, further reducing the friction on the mold and improving the protection effect on the mold.

[0017] When the movable plate moves to the surface of the smooth rod, the movable plate is pushed downward by the spring. At this time, the movable plate is always in contact with the one-way threaded rod. The rotating threaded rod and the movable plate rub against each other. Therefore, applying lubricating oil on the one-way threaded rod can protect the movable plate.

[0018] And under the action of the spring, when the first motor is reversed, the movable plate can be engaged with the movable plate again, thus preparing for working again.

[0019] Preferably, the ball is made of stainless steel, and the surface of the ball is a mirror surface.

[0020] Since stainless steel has good wear resistance and a smooth mirror surface, it can reduce the friction on the mold when rotating the mold, thus protecting the mold.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. The present application sets a movable plate and a one-way threaded rod, and the output end of the first motor drives the one-way threaded rod to rotate, so that the movable plate can move up until the ball passes through the through hole and lifts up the mold. At this time, the staff can manually push the mold to move along the slide groove and limit the position of the mold through the side wall of the slide groove. In this process, the rolling friction force on the mold is small, so that the mold can be protected;

[0023] 2. In the present application, fan blades, a smooth rod and a spring are arranged. During the rotation of the first motor, the one-way threaded rod drives the fan blades to rotate. At this time, the fan blades blow air upward, so that the gas can pass through the gap between the ball and the movable plate, and then move upward through the through holes and the air holes, directly impacting the surface of the mold, thereby cleaning the bottom wall of the mold.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0032] See also Figures 1 to 4 , the utility model provides a technical solution:

[0033] A clamping device for precision mold processing includes a workbench 1, characterized in that: a socket 2 is opened on the top wall of the workbench 1, a support plate 3 is fixedly installed in the socket 2, a movable plate 4 is slidably installed in the socket 2, balls 5 are evenly and movably embedded on the top wall of the movable plate 4, a through hole 6 cooperating with the ball 5 is opened on the top wall of the support plate 3, and a first motor 7 is fixedly installed on the inner bottom wall of the workbench 1, a one-way threaded rod 8 is fixedly installed on the output end of the first motor 7, the one-way threaded rod 8 passes through the movable plate 4, and the movable plate 4 is threadedly connected with the one-way threaded rod 8; two mutually cooperating limit rods 9 are arranged on the top wall of the workbench 1, and mutually cooperating slide grooves 10 are symmetrically opened on the side walls of the adjacent sides of the two limit rods 9; and a fixing mechanism is provided on the limit rod 9.

[0034] A mounting frame 11 is fixedly mounted on the top wall of the workbench 1, a bidirectional threaded rod 12 is rotatably mounted on the mounting frame 11, two mounting blocks 13 are symmetrically threadedly mounted on the bidirectional threaded rod 12, the limiting rod 9 is fixedly mounted on the mounting block 13, and a second motor 14 with an output end fixedly connected to the bidirectional threaded rod 12 is provided on the workbench 1.

[0035] A mounting hole 15 is provided on the side wall of the slide groove 10 , a stopper 16 is slidably installed in the mounting hole 15 , a threaded column 17 penetrating the mounting hole 15 is horizontally fixedly installed on the side wall of the stopper 16 , and a fastening nut 18 is threadedly installed on the threaded column 17 .

[0036] First, the number of revolutions of the second motor 14 is adjusted according to the size of the mold, thereby adjusting the distance between the two limit rods 9, and then the mold is placed between the two slide grooves 10, and then the position of the stopper 16 is moved along the mounting hole 15. After the stopper 16 moves to the specified position, the stopper 16 is fixed by rotating the fastening nut 18, thereby limiting the staying position of the mold moving along the slide groove 10.

[0037] The moving direction of the mold is limited by the side wall of the slide groove 10, and then the first motor 7 is started. At this time, the output end of the first motor 7 drives the one-way threaded rod 8 to rotate, so that the movable plate 4 can move up until the ball 5 passes through the through hole 6 and lifts the mold. At this time, the staff can manually push the mold to move along the slide groove 10 and limit the position of the mold by the side wall of the slide groove 10. In this process, the rolling friction force on the mold is small, so that the mold can be protected, the degree of wear of the mold is reduced, and the mold is protected.

[0038] Specifically, Figure 3 As shown, air holes 19 are evenly opened on the bottom wall of the slide groove 10, fan blades 20 are arranged on the one-way threaded rod 8, and a delay mechanism cooperating with the fan blades 20 is arranged on the one-way threaded rod 8.

[0039] The delay mechanism comprises a smooth rod 21 fixedly mounted on the one-way threaded rod 8 , and a spring 22 cooperating with the movable plate 4 is fixedly mounted on the bottom wall of the support plate 3 .

[0040] The surface of the spring 22 is coated with lubricating oil.

[0041] During the rotation of the first motor 7, the one-way threaded rod 8 drives the fan blade 20 to rotate. At this time, the fan blade 20 blows air upward, so that the gas can pass through the gap between the ball 5 and the movable plate 4, and then move upward through the through hole 6 and the air hole 19 to directly impact the surface of the mold, thereby cleaning the bottom wall of the mold, further reducing the friction on the mold, and improving the protection effect of the mold.

[0042] When the movable plate 4 moves to the surface of the smooth rod 21, the movable plate 4 is pushed downward by the spring 22. At this time, the movable plate 4 is always in contact with the one-way threaded rod 8, and the threaded rod in a rotating state and the movable plate 4 rub against each other. Therefore, by applying lubricating oil on the one-way threaded rod 8, the movable plate 4 is protected.

[0043] And under the action of the spring 22, when the first motor 7 is reversed, the movable plate 4 can be engaged with the movable plate 4 again, which plays a role in preparing for working again.

[0044] Specifically, Figure 3 As shown, the ball 5 is made of stainless steel, and the surface of the ball 5 is a mirror surface.

[0045] Since stainless steel has good wear resistance and a smooth mirror surface, it can reduce the friction on the mold when rotating the mold, thus protecting the mold.

[0046] Working principle: First, adjust the number of revolutions of the second motor 14 according to the size of the mold, thereby adjusting the distance between the two limit rods 9, and then prevent the mold from being located between the two slide grooves 10, and then move the position of the stopper 16 along the mounting hole 15. After the stopper 16 moves to the specified position, fix the stopper 16 by rotating the fastening nut 18, thereby limiting the staying position of the mold moving along the slide groove 10.

[0047] The moving direction of the mold is limited by the side wall of the slide groove 10, and then the first motor 7 is started. At this time, the output end of the first motor 7 drives the one-way threaded rod 8 to rotate, so that the movable plate 4 can move up until the ball 5 passes through the through hole 6 and lifts the mold. At this time, the staff can manually push the mold to move along the slide groove 10, and limit the mold position by the side wall of the slide groove 10. In this process, the rolling friction force applied to the mold is small, thereby protecting the mold and reducing the degree of wear of the mold. During the rotation of the first motor 7, the one-way threaded rod 8 drives the fan blade 20 to rotate. At this time, the fan blade 20 blows air upward, so that the gas can pass through the gap between the ball 5 and the movable plate 4, and then pass through the through hole 6 and the air hole 19 to move up, directly impacting the surface of the mold, so that the bottom wall of the mold can be cleaned, further reducing the friction force applied to the mold and improving the protection effect of the mold.

[0048] When the movable plate 4 moves to the surface of the smooth rod 21, the movable plate 4 is pushed downward by the spring 22. At this time, the movable plate 4 is always in contact with the one-way threaded rod 8, and the threaded rod in a rotating state and the movable plate 4 rub against each other. Therefore, by applying lubricating oil on the one-way threaded rod 8, the movable plate 4 is protected.

[0049] And under the action of the spring 22, when the first motor 7 reverses, the movable plate 4 can mesh with the movable plate 4 again, playing a role in preparing for working again. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace part or all of the technical features therein by equivalent; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
