DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] It is given by Figures 1-3 Figures 1-3

[0023] When this device is in use, the setting of one lead screw 3 makes the device more compact. The first guide rail 6 and the second guide rail 7 arranged in cooperation can increase the stability of the mold 5 during movement.

[0024] The cross-section of the first guide rail 6 has a convex structure with a stepped surface. The first slider 10 is sleeved on the upper end of the first guide rail 6. A rotatable roller 15 is arranged in the first slider 10, and the lower end surface of the roller 15 presses on the stepped surface. The convex structure can ensure that when the mold 5 slides, the upper end of the convex shape can support the first slider 10, and the stepped surface can contact the lower surface of the first slider 10, thereby making the movement of the mold 5 more stable.

[0025] A driving motor 2 is fixedly connected to the upper end of the workbench 1, the lead screw 3 is fixedly connected to the output end of the driving motor 2, and two parallel fixed seats 8 are also fixedly connected to the workbench 1, and the lead screw 3 passes through the fixed seats 8.

[0026] A groove 9 is opened at the lower end of the fixed block 4. Two symmetrically arranged clamping blocks 13 are arranged in the groove 9. The clamping blocks 13 can approach / separate from each other. Semi-circular grooves are opened on the opposite side surfaces of the two clamping blocks 13, and the semi-circular grooves can just be stuck on the lead screw 3.

[0027] Connecting blocks 12 are fixedly connected to the upper ends of the two clamping blocks 13. A bolt rod 14 that can rotate is arranged in the fixed block 4. The screw rod 14 passes through the two connecting blocks 12, and the screw rod 14 is in threaded connection with the connecting blocks 12. One end of the screw rod 14 extends to the side surface of the fixed block 4 away from the mold 5.

[0028] When the mold 5 needs to be replaced, the user only needs to rotate the screw rod 14 to make the two clamping blocks 13 separate from each other, and then the mold 5 can be removed. When the two clamping blocks 13 approach and abut against each other, the semi-circular grooves can form a complete circular groove, which is sleeved outside the lead screw 3 and cooperates with the lead screw 3. Since the two clamping blocks 13 are symmetrically arranged, when the screw rod 14 rotates, the two clamping blocks 13 can approach / separate from each other.

[0029] A strip-shaped limiting groove is formed in the upper wall of the groove 9. The connecting block 12 is inserted into the strip-shaped limiting groove, and the connecting block 12 can move along the strip-shaped limiting groove. The use of the limiting groove can prevent the connecting block 12 from rotating and ensure the stability of the clamping block 13.

[0030] A disc is fixedly connected to one end of the screw rod 14. A circular groove is formed in the fixed block 4. The disc is located in the circular groove and can rotate in the circular groove so that the screw rod 14 can only rotate in its original position.

[0031] The number of rollers 15 is multiple, and they are symmetrically arranged on both sides of the first slider 10.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
