Description

Technical Field

[0001] The utility model relates to the technical field of graphite mold manufacturing, in particular to a clamping fixture for manufacturing graphite molds. Background Art

[0002] Graphite mold is a mold made of graphite material, which is widely used in various industrial production. Graphite mold has excellent thermal conductivity, electrical conductivity, high temperature resistance, chemical stability and self-lubrication, which makes it widely used in many fields.

[0003] The traditional clamping fixture for graphite mold manufacturing is a bidirectional screw that drives two clamping blocks. The motor drives the bidirectional screw to drive the two clamping blocks to move toward each other, thereby clamping the graphite mold.

[0004] This type of clamping fixture for graphite mold manufacturing has the following disadvantages: the hardness of graphite is relatively low, and the motor directly drives the clamping block to clamp. If the clamping is too tight, the graphite mold surface will be damaged, and if the clamping is too loose, it will affect production. For this reason, we propose a clamping fixture for graphite mold manufacturing. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a clamping fixture for manufacturing graphite molds. Through the cooperation of a spring and a clamping block, a certain buffering force is generated after clamping the graphite mold raw material. Then, by locking the clamping block, the surface of the graphite mold is protected while the clamping is more stable, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a clamping fixture for manufacturing a graphite mold, comprising a mounting seat, a sliding groove is provided in the middle of the mounting seat, and a clamping mechanism;

The limiting strip and the limiting slot are cooperated with each other. Through the cooperation of the spring and the clamping block, a certain buffer force is generated after clamping the graphite mold raw material, and then the locking clamping block is locked to protect the surface of the graphite mold while clamping more firmly.

[0008] Furthermore, a control switch is provided at the front left end of the mounting seat, and an input end of the control switch is electrically connected to an external power supply to control the motor.

[0009] Furthermore, the clamping mechanism also includes a spring 1, which is arranged between the relative inner side of the clamping seat and the side of the clamping block away from the center of the mounting seat. The spring 1 is sleeved on the outer surface of the guide column to provide rebound force for the clamping block.

[0010] Furthermore, the clamping mechanism also includes rubber gaskets, which are arranged on the relatively inner sides of the clamping blocks to protect the surface of the graphite mold.

[0011] Furthermore, the locking assembly also includes spring 2, which is arranged between the side of the locking column close to the center of the mounting seat and the inner wall of the circular hole. The spring 2 is sleeved on the outer surface of the locking column to provide rebound force for the locking column.

[0012] Furthermore, the locking assembly also includes a knob, which is arranged on a side of the locking column away from the center of the mounting seat to drive the locking column.

The opposite inner sides of the two groups of guide columns 33 are provided with a clamping block 34. The locking assembly 37 includes a locking column 371, a locking groove 372, a limit bar 373 and a limit groove 375. The circular holes on the front and rear sides of the clamping seat 32 are slidably connected with locking columns 371. The guide columns 33 are away from the center of the mounting seat 1. The center is provided with evenly distributed locking grooves 372 on one side, and the locking grooves 372 are installed in conjunction with the longitudinally adjacent locking columns 371. The upper end of the locking column 371 close to the center of the mounting seat 1 is provided with a limit strip 373, and the upper end of the inner wall of the circular hole is provided with a limit groove 375.

[0027] The working principle of the clamping fixture for graphite mold manufacturing provided by the present invention is as follows: when the graphite mold needs to be manufactured, the raw material for the graphite mold needs to be placed in the middle of the mounting seat 1 first, and then the motor 5 is turned on by the control switch 4. The output shaft of the motor 5 drives the bidirectional screw rod 6 to drive the two sliders 31 to move towards each other, and drives the two clamping seats 32 to move towards each other, and finally the two clamping blocks 34 clamp the graphite mold raw material until the two clamping seats 32 contact. At the same time, the mold raw material will clamp the two clamping blocks 34 pushes toward both sides and squeezes spring 1 35 to make it contract. After the two clamping seats 32 come into contact, the knob 374 is pressed. The knob 374 drives the locking column 371 to insert into the locking groove 372. Since the limiting groove 375 is an L-shaped groove, after the locking column 371 is inserted into the locking groove 372, the limiting bar 373 will follow and move to the bottom of the limiting groove 375. Then, the locking column 371 is rotated clockwise to make the limiting bar 373 enter the horizontal groove of the L-shaped groove, thereby locking the clamping block 34 and completing the clamping of the graphite mold raw material.
