Description

Technical Field

[0001] This utility model relates to the field of mold changing device technology, specifically a quick mold changing device for shoe sole molds. Background Technology

[0002] Shoe molds are industrial molds used to produce footwear such as athletic shoes, beach shoes, and slippers. They are mainly used to form shoe soles and uppers through processes such as injection molding, cold pressing, or blow molding. The core of the mold is the sole mold, which needs to be adapted to the physical properties of various materials such as RB (rubber), EVA, and TPU. The design of the flow channel structure and parting surface direction is based on the curvature of the shoe shape to ensure the comfort and precision of the finished product.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the connection between shoe sole molds and workbenches is generally achieved by bolts through and fixing them. A single shoe sole mold usually requires multiple sets of bolts for fastening. When changing molds, operators need to use a wrench to loosen the bolts one by one, remove the old mold, and then align the new mold and tighten the bolts. If the force is uneven when tightening the bolts, it can easily cause a slight misalignment between the mold and the workbench. This positioning deviation can cause quality problems such as flash and dimensional discrepancies during shoe sole molding.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quick mold changing device for shoe sole molds, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a quick mold changing device for shoe sole molds, so as to solve the problem mentioned in the background art that the connection between shoe sole molds and worktables is generally fixed by bolts, which is inconvenient to disassemble and assemble and is prone to positioning deviation.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A quick mold changing device for shoe sole molds includes a main body, a reinforcing mechanism, and a shoe mold body. The main body includes a base, with slide rods fixedly installed at both ends inside the base. A pair of movable plates are slidably installed between a pair of slide rods. The reinforcing mechanism includes a pair of placement frames, with the bottom ends of the pair of placement frames respectively connected to the top ends of the pair of movable plates. An adjustment frame is fixedly installed on one side of the upper end of each placement frame. Several pairs of clamping blocks are slidably installed on the opposing surfaces of each pair of adjustment frames. The shoe mold body is disposed between each pair of clamping blocks, and the opposing surfaces of each pair of clamping blocks abut against the outer ends of both ends of the shoe mold body.

[0008] Furthermore, both ends of the adjustment frame are rotatably connected to a first bidirectional screw, and a second bidirectional screw is connected between each pair of first bidirectional screws.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the first bidirectional screw and the second bidirectional screw cooperate to provide synchronous adjustment power for the clamping blocks. Rotating the first bidirectional screw can drive multiple pairs of clamping blocks to move in opposite directions at the same time, ensuring that the clamping force of each clamping block on the shoe mold body is uniform and improving the fixation stability.

[0010] Furthermore, both ends of the first and second bidirectional screws are threaded with sliders, and each pair of sliders is fixedly connected to its corresponding clamping block.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the slider is threadedly connected to the first bidirectional screw and the second bidirectional screw, which converts the rotational motion of the first bidirectional screw and the second bidirectional screw into the linear sliding of the clamping block, realizes the precise displacement of the clamping block, ensures that each pair of clamping blocks can fit tightly against both sides of the shoe mold body, and enhances the fixing effect.

[0012] Furthermore, one end of the first bidirectional screw extends outward through the adjusting frame and is fitted with a first rotating wheel.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the first rotating wheel provides a convenient manual drive for the first bidirectional screw, which makes it easy for the operator to quickly adjust the position of the clamping block, realize the quick clamping and loosening of the shoe mold body, and improve the mold changing efficiency.

[0014] Furthermore, a movable frame is fixedly installed at the bottom of the base, and a third bidirectional screw is rotatably connected inside the movable frame.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the third bidirectional screw in the movable frame provides power for the sliding of the movable plate. Rotating the third bidirectional screw can simultaneously adjust the distance between a pair of movable plates, thereby adjusting the distance between the placement frames and initially fixing the two ends of the shoe mold body.

[0016] Furthermore, both ends of the third bidirectional screw are threadedly connected to movable blocks, and both ends of the movable blocks are fixedly installed with connecting blocks. The top of each pair of connecting blocks is fixedly connected to the bottom of a pair of movable plates.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the movable block is threadedly connected to the third bidirectional screw, and the moving plate is driven to slide smoothly along the slide bar through the connecting block, ensuring that a pair of moving plates move synchronously in opposite directions, so as to make the spacing of the placement frame accurately adjusted and ensure that the shoe mold body is placed in the center.

[0018] Furthermore, one end of the third bidirectional screw extends through the base to the outside and is fitted with a second rotating wheel.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the second rotating wheel allows the operator to manually rotate the third bidirectional screw, and the distance between the moving plates can be quickly adjusted through simple operation. Combined with the adjustment of the clamping block, the shoe mold body can be quickly replaced, simplifying the mold changing process and improving the ease of operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In the main body of this quick mold changing device for shoe sole molds, the movable plate slides along the slide rod, which can adjust the spacing of a pair of placement frames, facilitating the initial fixation of shoe mold bodies in the same batch; the clamping blocks of the reinforcing mechanism slide on the adjusting frame, which can clamp the shoe mold body from both sides, further fixing the two sides of the shoe mold body. Combined with the fixation of the two ends of the shoe mold body by the placement frames, the fixing effect of the shoe mold body and the positioning accuracy are improved. The whole device achieves quick replacement and precise positioning of shoe molds through sliding adjustment, reducing mold changing time and improving production efficiency. The first bidirectional screw and the second bidirectional screw cooperate to provide synchronous adjustment power for the clamping blocks. Rotating the first bidirectional screw can drive multiple pairs of clamping blocks to move simultaneously in opposite directions, ensuring that the clamping force of each clamping block on the shoe mold body is uniform and improving the fixing stability.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a quick mold changing device for shoe sole molds, comprising a main body 1, a reinforcing mechanism 2, and a shoe mold body 3. The main body 1 includes a base 101, with slide rods 102 fixedly installed at both ends inside the base 101, and a pair of movable plates 103 slidably installed between the pair of slide rods 102. The reinforcing mechanism 2 includes a pair of placement frames 201, the bottom ends of the pair of placement frames 201 being connected to the top ends of the pair of movable plates 103 respectively, and an adjusting frame 202 fixedly installed on one side of the upper end of each placement frame 201. Several pairs of clamping blocks 203 are slidably installed on the opposing surfaces of the pair of adjusting frames 202, and the shoe mold body 3 is disposed between each pair of clamping blocks 203. Each pair of clamping blocks 203 has its facing surfaces abutting against the outer sides of both ends of the shoe mold body 3. In the main body 1, the movable plate 103 slides along the slide rod 102, which can adjust the spacing between a pair of placement racks 201, making it convenient to initially fix the shoe mold bodies 3 of the same batch. The clamping blocks 203 of the reinforcing mechanism 2 slide on the adjustment rack 202, which can clamp the shoe mold body 3 from both sides, further fixing the two sides of the shoe mold body 3. Together with the placement rack 201 fixing the two ends of the shoe mold body 3, the fixing effect of the shoe mold body 3 and the positioning accuracy are improved. The whole system realizes the quick replacement and precise positioning of the shoe mold through sliding adjustment, reducing the mold replacement time and improving production efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5The adjusting frame 202 has a first bidirectional screw 205 rotatably connected to both ends inside. A second bidirectional screw 206 is connected between each pair of first bidirectional screws 205. A slider 207 is threaded to both ends of the first bidirectional screws 205 and the second bidirectional screws 206. Each pair of sliders 207 is fixedly connected to its corresponding clamping block 203. One end of one of the first bidirectional screws 205 extends through the adjusting frame 202 to the outside and is fitted with a first rotating wheel 204. A movable frame 105 is fixedly installed at the bottom inside the base 101. A third bidirectional screw 106 is rotatably connected inside the movable frame 105. Both ends of the third bidirectional screw 106 are threaded. A movable block 107 is connected, and connecting blocks 108 are fixedly installed at both ends of the movable block 107. The top of each pair of connecting blocks 108 is fixedly connected to the bottom of a pair of movable plates 103. One end of the third bidirectional screw 106 extends through the base 101 to the outside and is fitted with a second rotating wheel 104. The first bidirectional screw 205 cooperates with the second bidirectional screw 206 to provide synchronous adjustment power for the clamping blocks 203. Rotating the first bidirectional screw 205 can drive multiple pairs of clamping blocks 203 to move simultaneously in opposite directions, ensuring that the clamping force of each clamping block 203 on the shoe mold body 3 is uniform and improving the fixing stability. The slider 207 is connected to the first bidirectional screw 205 and the second bidirectional screw 106. The screw 206 is threaded, converting the rotational motion of the first bidirectional screw 205 and the second bidirectional screw 206 into the linear sliding motion of the clamping block 203. This achieves precise displacement of the clamping block 203, ensuring that each pair of clamping blocks 203 can tightly fit against both sides of the shoe mold body 3, enhancing the fixing effect. The first rotating wheel 204 provides a convenient manual drive for the first bidirectional screw 205, allowing operators to quickly adjust the position of the clamping block 203, enabling rapid clamping and loosening of the shoe mold body 3 and improving mold changing efficiency. The third bidirectional screw 106 inside the moving frame 105 provides power for the sliding of the moving plate 103. Rotating the third bidirectional screw 106 can simultaneously adjust a pair of moving plates. The spacing of 103 is adjusted to further adjust the distance between the placement racks 201, and the two ends of the shoe mold body 3 are initially fixed. The movable block 107 is threadedly connected to the third bidirectional screw 106. The moving plate 103 is driven to slide smoothly along the slide bar 102 through the connecting block 108, ensuring that a pair of moving plates 103 move synchronously in opposite directions, so that the spacing of the placement racks 201 is accurately adjusted and the shoe mold body 3 is placed in the center. The second rotating wheel 104 allows the operator to manually rotate the third bidirectional screw 106. The spacing of the moving plates 103 can be quickly adjusted through simple operation. With the adjustment of the clamping block 203, the shoe mold body 3 can be quickly replaced, simplifying the mold replacement process and improving the convenience of operation.

[0031] Specifically, the working principle of this quick mold changing device for shoe sole molds is as follows: During use, the base 101 is installed at a suitable position on the workbench. The operator rotates the second rotating wheel 104, causing the third bidirectional screw 106 to rotate within the movable frame 105. This causes the movable block 107 to slide along the slide bar 102 via the connecting block 108, adjusting the spacing between the pair of placement frames 201 to initially match the length of the shoe mold body 3. Then, the shoe mold body 3 is placed between the placement frames 201, and the first rotating wheel is rotated... 204 drives the first bidirectional screw 205 and the second bidirectional screw 206 to rotate, causing the slider 207 to drive the clamping block 203 to move towards each other on the adjusting frame 202, clamping the shoe mold body 3 from both sides. With the help of the placement frame 201 to limit the two ends of the shoe mold body 3, the shoe mold is stably fixed. When changing the shoe mold, the first rotating wheel 204 and the second rotating wheel 104 are rotated in the opposite direction to loosen the clamping block 203 and widen the spacing of the placement frame 201. The old shoe mold can be quickly removed and replaced with a new shoe mold, completing the entire mold changing process.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller.

Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
