[0026] More specifically, the distance between the two lower installation base plates 5 opposite left and right is adjusted by horizontal distance adjusting mechanism 6, so as to adjust the interval of the positioning column assemblies 12 on the left and right sides, and then the longitudinal displacement sliding block 9 is driven to move by longitudinal distance adjusting mechanism 11, so as to adjust the interval of the positioning column assemblies 12 on the front and back sides, and finally the positions of the four positioning column assemblies 12 are adapted to the positioning holes of the lower mold to be fixed, and the mold hole is sleeved on the surface of the positioning column assembly 12 and is fixed by the positioning column assembly 12, so that different specifications of molds can be adapted and fixed. For enterprises, there is no need to manufacture specially adapted molds, thereby effectively reducing production cost.

[0027] The downward driving mechanism 3 comprises a servo motor 301, a driving cylinder body 302 and a guide rod 303. The driving cylinder body 302 is fixedly installed on the top surface of the L-shaped support 2. The servo motor 301 is fixedly installed on the top surface of the driving cylinder body 302. The output end of the servo motor 301 is fixedly connected with the input end of the driving cylinder body 302. The guide rod 303 is slidingly inserted on the top surface of the L-shaped support 2. The upper mounting base plate 4 is fixedly installed on the bottom surface of the guide rod 303 and is fixedly connected with the output end of the driving cylinder body 302.

[0028] Specifically, the servo motor 301 and the driving cylinder body 302 cooperate to drive the upper mounting base plate 4 to ascend and descend, so that the upper die fixed on the bottom surface of the upper mounting base plate 4 completes the compression molding work. The guide rod 303 improves the stability of the upper mounting base plate 4 ascending and descending.

[0029] The lateral distance adjusting mechanism 6 comprises two symmetrical lateral sliding grooves 601 provided on the top surface of the lower mounting base plate 5. A lateral sliding block 602 is slidingly installed on the inner wall surface of the lateral sliding groove 601. A lateral moving seat 7 is fixedly installed on the top surface of the lateral sliding block 602. A lateral double-headed threaded rod 603 is rotatably provided on the inner wall surface of the lateral sliding groove 601 and penetrates through one side surface of the lower mounting base plate 5. A first knob 604 is fixedly installed on one end surface of the lateral double-headed threaded rod 603. The two lateral sliding blocks 602 are symmetrically screwed on the surface of the lateral double-headed threaded rod 603.

[0030] Specifically, rotating the first knob 604 drives the lateral double-headed threaded rod 603 to rotate, so that the two lateral sliding blocks 602 symmetrically screwed on the surface of the lateral double-headed threaded rod 603 and slidingly installed in the lateral sliding groove 601 move synchronously towards or away from each other, thereby adjusting the distance between the lateral moving seats 7 fixedly installed on the top surface of the lateral sliding blocks 602, adjusting the left-right distance between the longitudinal sliding blocks 9 arranged on the surface of the lateral moving seat 7, and finally adjusting the left-right distance between the positioning column assemblies 12. When the distance between the left-right opposite longitudinal sliding blocks 9 changes, the telescopic rods 10 also correspondingly extend or retract.

[0031] The longitudinal distance adjusting mechanism 11 comprises a longitudinal double-headed threaded rod 111 and a limiting sliding rod 113. The longitudinal double-headed threaded rod 111 is rotatably installed on the front surface of one lateral moving seat 7 and penetrates through the two longitudinal sliding grooves 8 arranged in front and back. The two longitudinal sliding blocks 9 are symmetrically screwed on the surface of the longitudinal double-headed threaded rod 111. The limiting sliding rod 113 is fixedly installed on the inner wall surface of the two longitudinal sliding grooves 8 on the other side. The longitudinal sliding block 9 is slidingly installed on the surface of the limiting sliding rod 113.

[0032] Specifically, rotating the second knob 112 drives the longitudinal double-ended threaded rod 111 to rotate, thereby causing the two longitudinal sliding sliders 9, whose symmetrical threads are installed on the surface of the longitudinal double-ended threaded rod 111 and slidably installed on the inner wall surface of the longitudinal slide groove 8, to move synchronously towards or away from each other, thereby adjusting the front-to-back distance between the two longitudinal sliding sliders 9 on the surface of the longitudinal double-ended threaded rod 111. Since a telescopic rod 10 is fixedly connected between the two longitudinal sliding sliders 9 on the left and right sides, the movement of the two longitudinal sliding sliders 9 on the surface of the longitudinal double-ended threaded rod 111 will be transmitted to the longitudinal sliding sliders 9 slidably installed on the surface of the limiting slide rod 113 through the telescopic rod 10, thereby realizing the synchronous movement of the longitudinal sliding sliders 9 on the left and right sides, and finally realizing the synchronous adjustment of the distance between the front-to-back positioning column assemblies 12 on the left and right sides.

[0033] The positioning post assembly 12 includes a positioning rod 121, which is fixedly installed on the top surface of the longitudinal sliding block 9. A threaded post 122 is fixedly installed on the top surface of the positioning rod 121. The diameter of the threaded post 122 is smaller than the diameter of the positioning rod 121. A compression sleeve 123 is threaded onto the outer surface of the threaded post 122. A smooth hole 125 is opened on the bottom surface of the compression sleeve 123. A threaded hole 124 is opened on the top surface of the inner wall of the smooth hole 125. The inner wall surface of the threaded hole 124 is threadedly connected to the outer surface of the compression sleeve 123. The inner wall surface of the smooth hole 125 is slidably set to fit against the outer surface of the positioning rod 121.

[0034] Specifically, the positioning hole of the lower mold to be fixed is slidably fitted onto the surface of the positioning rod 121, and then the extrusion sleeve 123 is threaded onto the surface of the threaded post 122. Depending on the height of the positioning hole, the extrusion sleeve 123 is rotated and screwed down to different degrees, so that the bottom surface of the extrusion sleeve 123 is pressed against the surface around the top of the positioning hole. When fixing lower molds with different positioning hole heights, the positioning rod 121 extends into the smooth hole 125 at different heights, which can adapt to the fixing requirements of lower molds of various specifications.

[0035] A support plate 13 is attached to the center of the top surface of the lower mounting base plate 5. The top surface of the support plate 13 is flush with the top surface of the longitudinal sliding slider 9. The length and width of the support plate 13 are available in several different sizes.

[0036] Specifically, during the pressing process, a support plate 13 is used to support the bottom of the lower mold. Support plates 13 with different lengths and widths can support lower molds of different sizes and are adapted to transverse mounting seats 7 and telescopic rods 10 with different spacings to ensure that the support plate 13 is located within the space enclosed by the transverse mounting seats 7 and telescopic rods 10.

[0037] In summary: By adjusting the distance between the two opposite lower mounting base plates 5 via the lateral adjustment mechanism 6, the spacing between the positioning post assemblies 12 on the left and right sides is adjusted. Then, by moving the longitudinal slider 9 via the longitudinal adjustment mechanism 11, the spacing between the positioning post assemblies 12 on the front and rear sides is adjusted. Ultimately, the positions of the four positioning post assemblies 12 are adapted to the positioning holes of the lower mold that needs to be fixed. By fitting the mold hole onto the surface of the positioning post assembly 12 and fixing it with the positioning post assembly 12, molds of different specifications can be adapted and fixed. For enterprises, there is no need to manufacture specially adapted molds, thereby effectively reducing production costs.
