Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-6 As shown, this utility model proposes a fixture for mold production, which mainly includes a frame 1, a sliding frame 2, a mounting base 3, an L-shaped rod 4, a return spring 12, and a placement plate 5.

[0034] The frame 1 includes support legs 102 and an operating table 101, with the operating table 101 positioned on top of the support legs 102. Two sliding frames 2 are symmetrically arranged, each sliding along the length of the operating table 101. Specifically, the sliding frames 2 are C-shaped or rectangular, effectively limiting their sliding trajectory by sliding them onto the operating table 101. Four mounting bases 3 are symmetrically arranged on the two sliding frames 2. Four L-shaped rods 4 are also present, with their middle portions rotatably mounted on the four mounting bases 3. Two L-shaped rods 4 are symmetrically arranged on each sliding frame 2. Each end of one L-shaped rod 4 is rotatably equipped with a stop wheel 6, which abuts against the outer wall of the mold, enhancing clamping stability. The stop wheels 6 are made of rubber to prevent damage to the outer wall of the mold. Four return springs 12 are correspondingly arranged to the four L-shaped rods 4, with one end of each return spring 12 rotatably connected to a mounting base 3 and the other end rotatably connected to one end of an L-shaped rod 4.

[0035] Each mounting base 3 can be adjusted in position on the sliding frame 2. Specifically, the top surface of the sliding frame 2 has two rows of adjustment holes 7, and each row includes multiple adjustment holes 7 arranged along the width direction of the operating table 101. Two positioning holes are respectively opened on both sides of the mounting base 3, and a positioning pin 8 passes through each positioning hole. The bottom of each positioning pin 8 passes through one of the adjustment holes 7. The specific adjustment steps are as follows: remove the positioning pin 8, move the mounting base 3 to the appropriate position, aligning its positioning hole with the nearest adjustment hole 7, and then insert the positioning pin 8 into the positioning hole and adjustment hole 7 in sequence. This completes the adjustment of the position of the mounting base 3. The design is reasonable, easy to operate, and facilitates the adjustment of the interval between the two L-shaped rods 4 on the same sliding frame 2 according to the size of the mold, thus making it suitable for molds of different sizes and highly practical.

[0036] Two sliding frames 2 are synchronously slidably mounted on the operating table 101 via a transmission device 9. The transmission device 9 includes a connecting block 91 and an adjusting rod 92. There are two connecting blocks 91, which are fixedly connected to the bottom of the two sliding frames 2 respectively. Both connecting blocks 91 are provided with threaded holes. The adjusting rod 92 is rotatably mounted on the frame 1 via a motor 93. The motor 93 is fixedly mounted on the support leg 102. The two ends of the adjusting rod 92 are provided with threads of opposite directions. The two connecting blocks 91 are respectively sleeved on the two ends of the adjusting rod 92 through the threaded holes.

[0037] The placement plate 5 is jacked up and positioned in the middle of the operating table 101. A groove 10 for accommodating the placement plate 5 is provided in the middle of the operating table 101. When the placement plate 5 is fully contained within the groove 10, its top surface is flush with the top surface of the operating table 101. The placement plate 5 allows for adjustment of the height of the mold placed on it, ensuring the mold's height matches the height of the L-shaped rod 4, thus facilitating better clamping of the mold's four corners. Furthermore, after the mold processing is complete and the L-shaped rod 44 releases its clamping grip, the placement plate 5 can lift and raise the mold, facilitating its removal and avoiding the problem of difficulty in removal due to obstruction by the L-shaped rod 44. The design is reasonable and highly practical.

[0038] The placement plate 5 is raised and lowered on the frame 1 via an adjusting assembly 11. The adjusting assembly 11 includes an adjusting screw 111 and guide rods 113. The adjusting screw 111 is threaded through the bottom of the trough 10, and its top is rotatably connected to the bottom of the placement plate 5. The bottom of the adjusting screw 111 extends out of the trough 10 and is fixedly connected to a handle 112. Multiple guide rods 113 are slidably inserted longitudinally through the bottom of the trough 10, and their tops are fixedly connected to the bottom of the placement plate 5. The specific operating steps of the adjusting assembly 11 are as follows: rotating the handle 112 causes the adjusting screw 111 to rotate, raising or lowering it, thereby raising or lowering the placement plate 5 at the top of the adjusting screw 111. The guide rods 113 help prevent the adjusting screw 111 from spinning freely, ensuring its normal raising and lowering, and also limit the raising and lowering path of the placement plate 5.

[0039] In this embodiment, during use, the mold is first placed on the operating table 101, above the placement plate 5. Then, the height of the placement plate 5 is adjusted by the adjusting component 11 so that the abutment roller 6 can abut against the center of the mold, ensuring a clamping effect. Then, the motor 93 is started, driving the adjusting rod 92 to rotate. The adjusting rod 92, through its oppositely screwed ends, drives the two connecting blocks 91 to slide simultaneously towards the center of the operating table 101. The connecting blocks 91 drive the sliding frame 2 to slide, thereby causing the four L-shaped rods 4 to converge towards the mold simultaneously, clamping the four corners of the mold, so that the abutment roller 6 abuts against the side walls at the four corners of the mold, thus completing the clamping of the mold (e.g., Figure 5 As shown), the design is reasonable, the operation is convenient, and the clamping effect is good, avoiding displacement during mold processing. In this utility model, the L-shaped rod 44 is rotatably mounted on the mounting base 3. In the initial state, the L-shaped rod 44 is in the state where the opening faces the L-shaped rod 44 on the opposite sliding frame 2 under the tension of the return spring 12 (as shown). Figure 4As shown, as the sliding frame 2 gradually approaches the mold, the four corners of the mold push the four L-shaped rods 44 to rotate, eventually causing the sidewalls at the four corners to abut against the abutment rollers 6, and at this time, the return spring 12 is in a stretched state. The rotation setting of the L-shaped rods 44 is beneficial for providing a slight buffer adjustment for molds with minor defects (minor defects such as angles slightly larger or smaller than 90 degrees), so that molds with minor shape defects can also be clamped. The design is reasonable and highly practical.

[0040] After the mold processing is completed, the motor 93 reverses, causing the sliding frame 2 to slide in the opposite direction. After the L-shaped rod 44 is released from the clamping of the mold, it returns to its original position under the tension of the return spring 12 (e.g., Figure 4 (As shown). At this time, the adjusting component 11 drives the placement plate 5 to rise, pushes the mold upward, and removes the mold.

[0041] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
