[0002] Molds are various molds and tools used in industrial production to obtain the required products through methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. They mainly realize the processing of the shape of the object by changing the physical state of the molded material. In the working use of mechanical molds, a base plate equipment is required to support and place the mechanical molds.

[0003] Chinese patent number CN218577086U proposes a mechanical mold base plate. Although it is designed with a connection mechanism, by aligning the bottom of the mold with the guide wheel first, and then putting down the mold, the mold slides from the guide wheel to the bottom of the connection plate due to gravity to control the movable plate and squeeze the first spring to perform compression movement, so as to place the mold. However, the slide rod and spring in this design do not have a locking function, so the mold cannot be stably clamped. External shaking can easily cause the mold to separate from the base plate, and the fixing effect is poor. Now there is an urgent need for a mechanical mold base plate to solve the above problems. Utility Model Content

[0006] Furthermore, a positioning groove is provided inside the fixing seat, and the clamping and fixing block slides tightly along the inner wall of the positioning groove through the positioning column.

[0007] Furthermore, the sliding groove is interconnected with the interior of the positioning groove, the limiting groove and other specifications are provided in a plurality of groups, and the limiting clamping block and the limiting groove are engaged with each other.

[0008] Furthermore, a limiting through hole is provided inside the fixing seat, the limiting column slides tightly along the inner wall of the limiting through hole, and a compression spring is sleeved on the outer side surface of the limiting column.

[0009] Furthermore, the through slot is communicated with the inside of the slide slot, a shift plate is slidably arranged inside the through slot, and the shift plate and the limit block are bonded and fixed to each other.

[0010] Furthermore, a return spring is arranged inside the slide groove, and two ends of the return spring are respectively fixedly connected to the inner wall of the slide groove and the inner side surface of the shift plate.

[0011] Furthermore, a guide slope is provided on the inner side surface of the clamping and fixing block, and a plurality of groups of balls are embedded inside the guide slope.

[0012] The beneficial effects of the utility model: the utility model provides a mechanical mold base plate, because the utility model adds a clamping and fixing block, a positioning column, a limit column, a limit card block and a limit card slot, the user squeezes the clamping and fixing blocks at both ends of the mold through the guiding slope and the ball during the placement process, so that the two groups of clamping and fixing blocks move away from each other and compress the extrusion spring until the clamping and fixing blocks clamp the two ends of the mold, at this time the reset spring drives the shift plate and the limit card block to reset, and at the same time the limit card block and the limit slot engage with each other, thereby limiting the positioning column, at this time the two groups of clamping and fixing blocks cannot move away from each other, but can only be relatively close to each other, thereby forming a self-locking, and this design can prevent the mold and the clamping and fixing block from shaking due to external force, causing the mold to shift or detach.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a mechanical mold bottom plate, including a base 1, a fixed seat 2, a clamping and fixing block 3, a positioning column 4, a limiting groove 5, a limiting column 6, a slide groove 7, a limiting block 8 and a through groove 9. The fixed seat 2 is symmetrically arranged on both sides of the front and rear ends of the upper end surface of the base 1, a slide groove 7 is opened inside the fixed seat 2, a limiting block 8 is slidably arranged inside the slide groove 7, a through groove 9 is opened on the upper end surface of the fixed seat 2, a clamping and fixing block 3 is slidably arranged on the upper end surface of the base 1, a positioning column 4 is arranged at one end outside the clamping and fixing block 3, a limiting groove 5 is opened on the inner side of the positioning column 4, and a limiting column 6 is arranged at one end outside the clamping and fixing block 3. This design solves the problem that the original mechanical mold bottom plate has a poor fixing effect on the mold.

[0021] As the first embodiment of the utility model: a positioning groove 21 is provided inside the fixing seat 2, and the clamping and fixing block 3 slides tightly along the inner wall of the positioning groove 21 through the positioning column 4, and the positioning groove 21 is used to limit the positioning column 4, and the positioning groove 21 and the positioning column 4 can guide and position the moving trajectory of the clamping and fixing block 3, and the slide groove 7 is connected to the inside of the positioning groove 21. This design makes the end of the limiting block 8 located inside the slide groove 7 extend into the inside of the positioning groove 21, and the limiting groove 5 and other specifications are provided with several groups, and the limiting groove 5 cooperates with the limiting block 8 to limit the clamping and fixing block 3, and the limiting block 8 and the limiting groove 5 are engaged with each other. The design of the limiting groove 5 and the limiting block 8 makes the two groups of clamping and fixing blocks 3 only approach each other but cannot move away from each other, and a limiting through hole 62 is provided inside the fixing seat 2, and the limiting column 6 slides tightly along the inner wall of the limiting through hole 62, and the outer side of the limiting column 6 is sleeved with an extrusion spring The spring 61, the limit column 6 and the limit through hole 62 make the movement of the clamping and fixing block 3 more stable. The clamping and fixing block 3 can drive the limit column 6 to move together and compress the extrusion spring 61. The extrusion spring 61 can help the clamping and fixing block 3 to reset. The through groove 9 is connected with the inside of the slide groove 7. A dial plate 81 is slidably arranged inside the through groove 9. The dial plate 81 and the limit card block 8 are bonded and fixed to each other. The dial plate 81 can drive the limit card block 8 to move together. This design is convenient for users to drive the limit card block 8 to move through the dial plate 81. A return spring 82 is arranged inside the slide groove 7. The two ends of the return spring 82 are fixedly connected to the inner wall of the slide groove 7 and the inner side of the dial plate 81 respectively. The return spring 82 can help the dial plate 81 and the limit card block 8 to reset. The clamping and fixing block 3 is provided with a guide slope 31 on the inner side relative to the inner side. A plurality of groups of balls 32 are embedded in the guide slope 31. The guide slope 31 and the balls 32 are convenient for the placement of the mold.

[0022] As a second embodiment of the present invention: the user first pulls the dial plate 81 outwards, so that the dial plate 81 moves along the inner wall of the slide groove 7 while driving the limit block 8 to move together and be retracted into the slide groove 7, releasing the mutual engagement state of the limit block 8 and the limit groove 5, so that the movement of the positioning column 4 is no longer restricted at this time, and then the mold is placed on the base 1 and lowered for placement. During the placement process, the two ends of the mold squeeze the clamping and fixing blocks 3 through the guiding slopes 31 and the balls 32, so that the two groups of clamping and fixing blocks 3 move away from each other and compress the squeezing spring 61 until the clamping and fixing blocks 3 clamp the two ends of the mold. At this time, the reset spring 82 drives the dial plate 81 and the limit block 8 to reset, and at the same time, the limit block 8 and the limit groove 5 are engaged with each other, thereby limiting the positioning column 4. At this time, the two groups of clamping and fixing blocks 3 cannot move away from each other, but can only be relatively close to each other, thereby forming a self-locking. This design can prevent the external force from driving the mold and the clamping and fixing blocks 3 to shake, causing the mold to deviate or detach.
