Description

Technical Field

[0001] This utility model relates to the field of 3D molds for shoe shapes, specifically a 3D mold that facilitates quick changes in shoe shapes. Background Technology

[0002] 3D molds for shoe designs are precision manufacturing tools that play a crucial role in the footwear industry. They are made through digital design and high-precision 3D printing or CNC machining technology, and can accurately represent the three-dimensional shape, structural details and size specifications of the shoe. This provides accurate reference and physical models for subsequent production processes such as upper cutting, sole molding and whole shoe assembly.

[0003] However, current 3D molds for shoe designs can only be used to manufacture one specific shoe model. If a shoe model needs to be changed frequently, the mold replacement becomes quite cumbersome. This not only significantly increases the time cost in the production process, disrupting the originally tight production rhythm and extending the order delivery cycle, but also significantly increases production costs. This is because each mold replacement requires manpower and resources for disassembly, installation, and debugging. In addition, frequent mold replacements may also affect the lifespan of the molds, increasing additional expenses for equipment maintenance and replacement, thus adversely affecting the company's market competitiveness and economic benefits. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a 3D mold that facilitates quick and easy replacement of shoe models, in order to solve the technical problems that existing 3D molds for shoe models can only be adapted to one type of shoe for manufacturing and processing. When frequently changing shoe models, the mold replacement process is cumbersome, which greatly increases production time and costs, disrupts the production rhythm, extends the order delivery cycle, and significantly increases production costs. Furthermore, frequent replacement may affect the service life of the mold and increase equipment maintenance and replacement expenses, thereby adversely affecting the company's market competitiveness and economic benefits.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 3D mold for quick shoe replacement, comprising a mold, the mold comprising a main mold frame, the main mold frame having grooves at both ends, and dovetail slide rails provided on both sides of the inner wall of the grooves, a quick-change template slidably connected in the grooves, the quick-change template having dovetail grooves on both sides, and the dovetail grooves engaging and sliding with the dovetail slide rails, the two ends of the quick-change template sliding through a transmission mechanism;

[0006] The transmission mechanism includes two sets of second cylinders. The output ends of the two sets of second cylinders are equipped with mounting rods through connecting frames. The ends of the mounting rods are equipped with quick-release heads, and the two sets of quick-release heads are fixedly connected to the front and rear ends of the quick-change template by bolts.

[0007] By adopting the above technical solution, through the interlocking and sliding design of the dovetail slide rail and the dovetail slide groove, combined with the second cylinder of the transmission mechanism driving the quick-release head to push and pull the quick-change template, the template can be directionally slid within the main mold frame, avoiding positioning deviations and mold wear caused by manual handling. At the same time, the quick-release head is rigidly connected to the template by bolts, ensuring structural stability under mold closing pressure.

[0008] Furthermore, the top of the quick-change template is provided with three types of shoe sole mold grooves.

[0009] By adopting the above technical solution, the top of the quick-change template integrates three shoe sole mold slots, which can be switched by sliding to adapt to different shoe model requirements, avoiding the need for overall mold disassembly and replacement, reducing downtime and mold storage space. At the same time, the modular design reduces the mold development cost for multiple product models.

[0010] Furthermore, the transmission mechanism enables the quick-change template to quickly change the shoe sole mold slot on the main mold frame.

[0011] By adopting the above technical solution, the transmission mechanism directly drives the quick-change template to slide through the linear output of the second cylinder, realizing the automated switching of the shoe sole mold slot, reducing the intensity of manual operation and the risk of error. At the same time, the cylinder drive has a fast response, shortening the shoe type switching cycle.

[0012] Furthermore, a fixing mechanism is provided below the main mold frame. The fixing mechanism includes a base, and the top four corners of the base are fixedly connected to the main mold frame through support legs.

[0013] By adopting the above technical solution, the base is fixedly connected to the main mold frame through the four corner support legs to form a stable frame structure, which disperses the mold closing pressure and suppresses vibration, ensuring the forming accuracy of the mold groove. At the same time, raising the main mold frame facilitates the installation and maintenance of the transmission mechanism.

[0014] Furthermore, a first cylinder is provided at the top axis of the base, and a plug block is provided at the top output end of the first cylinder.

[0015] By adopting the above technical solution, the first cylinder drives the plug-in block to rise and fall vertically. The plug-in block and the locking hole are engaged to achieve self-locking of the quick-change template station, ensuring that the target mold slot is accurately positioned in the center of the main mold frame processing area and eliminating the positioning deviation caused by sliding inertia.

[0016] Furthermore, the bottom of the quick-change template is provided with three locking holes, and the plug-in block is used to be inserted into the locking holes, so that one of the bottom mold slots can be placed in the processing area of ​​the main mold frame.

[0017] By adopting the above technical solution, three locking holes are opened at the bottom of the quick-change template, and the spacing between them matches the groove position of the shoe sole mold. By inserting the plug block into the target hole, the groove positioning of the multi-station template is realized, ensuring the consistency of the forming position after switching between different shoe types.

[0018] Furthermore, the second cylinder of the transmission mechanism drives the quick-release head to move axially along the mounting rod, causing the quick-change template to slide linearly along the dovetail slide rail, realizing the cyclic switching of the three shoe sole mold slots. When the target mold slot arrives at the processing area, the plug block is simultaneously inserted into the corresponding locking hole to complete the self-locking of the workstation.

[0019] By adopting the above technical solution, when the transmission mechanism drives the template to slide, the plug block simultaneously disengages from the current insertion hole; after the target mold slot is in place, the plug block immediately inserts into the new insertion hole, realizing the coordinated action of sliding and locking, avoiding the waste of time in manual step-by-step operation, and improving the reliability of the system through mechanical linkage.

[0020] Furthermore, the quick-change template has limit baffles connected to both sides by bolts, and the limit baffles are used to constrain the sliding stroke of the quick-change template to prevent the dovetail slide rail from separating from the dovetail slide groove.

[0021] By adopting the above technical solution, limit baffles are installed on both sides of the quick-change template with bolts to constrain the sliding stroke of the template, prevent the dovetail slide rail from separating from the dovetail slide groove due to overload impact, ensure sliding stability and reduce the risk of guide rail wear.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention solves the technical problems of existing 3D shoe molds, which can only be adapted to one type of shoe, have complicated replacement processes leading to increased production time and costs, disrupted production rhythm, extended order delivery cycles, and increased production costs. Furthermore, frequent replacements reduce mold life and increase equipment maintenance expenses, thus affecting the company's market competitiveness and economic benefits. Specifically, the transmission mechanism uses a second cylinder to drive the quick-change template to slide linearly along a dovetail slide rail, enabling cyclical switching of the three shoe sole mold slots. The driving control of the transmission mechanism via a transmission mechanism and the locking mechanism via a first cylinder ensures that the target mold slot is precisely fixed to the main mold frame processing area.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] A 3D mold that facilitates quick shoe model changes, such as Figure 1-4 As shown, the mold includes a mold 1, which includes a main mold frame 101. The main mold frame 101 has grooves at both ends. Dovetail slide rails 102 are provided on both sides of the inner wall of the grooves. A quick-change template 103 is slidably connected in the grooves. Dovetail slide grooves 104 are provided on both sides of the quick-change template 103. The dovetail slide grooves 104 engage with the dovetail slide rails 102 and slide. The two ends of the quick-change template 103 slide through the transmission mechanism 3.

[0031] The transmission mechanism 3 includes two sets of second cylinders 301. The output ends of both sets of second cylinders 301 are equipped with mounting rods 303 via connecting brackets 302. Quick-release heads 304 are provided at the ends of the mounting rods 303, and the two sets of quick-release heads 304 are fixedly connected to the front and rear ends of the quick-change template 103 respectively by bolts. Dovetail slide rails 102 are provided on both sides of the inner wall of the slide groove of the main mold frame 101, forming a locking and sliding pair with the dovetail slide grooves 104 on both sides of the quick-change template 103. The dovetail structure's inclined self-locking feature... To prevent the template from derailing or shifting during sliding, the two sets of second cylinders 301 of the transmission mechanism 3 drive the mounting rod 303 to move axially through the connecting frame 302, which in turn drives the quick-release head 304 to push and pull the quick-change template 103, realizing the linear displacement of the template along the slide groove. This replaces the traditional hoisting or forklift handling method, reduces the intensity of operation, and avoids mold collision damage. The quick-release head 304 forms a detachable rigid connection with both ends of the template through bolts, ensuring that the template resists deformation during high-pressure mold closing and maintains the molding accuracy of the shoe sole.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the quick-change template 103 is equipped with three types of shoe sole mold slots. The quick-change template 103 integrates the molding functions of different shoe types into a single movable template. The target shoe type slot can be switched to the processing area by driving the template to slide through the transmission mechanism 3. There is no need to disassemble the main mold frame 101 or replace the entire set of molds, which significantly reduces the downtime for mold change. The modular integrated design reduces the number of independent molds and reduces the cost of mold manufacturing, storage and management. It is especially suitable for the flexible production needs of small batch and multiple batches of shoe types, and solves the problem of production rhythm interruption caused by frequent mold changes in traditional production lines.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The transmission mechanism 3 enables the quick-change template 103 to quickly change the shoe sole mold slot on the main mold frame 101. The second cylinder 301 of the transmission mechanism 3 pushes the connecting frame 302 and the mounting rod 303 through the output end, so that the quick-release head 304 drives the quick-change template 103 to slide directionally along the dovetail slide rail 102, realizing the automated cyclic switching of three shoe sole mold slots. The linear output characteristics of the cylinder drive provide stable thrust, ensuring that the template sliding process is smooth and without jamming, avoiding positioning deviations caused by manual pushing and pulling. The pneumatic system responds quickly and is easy to integrate with the control unit. The shoe type switching can be completed through program instructions, reducing manual intervention, reducing the risk of operational errors and improving the continuity of the production line.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixing mechanism 2 is provided below the main mold frame 101. The fixing mechanism 2 includes a base 201. The top four corners of the base 201 are fixedly connected to the main mold frame 101 through support legs 202. The base 201 of the fixing mechanism 2 is rigidly connected to the bottom of the main mold frame 101 through four support legs 202, forming a high-rigidity support frame. This effectively disperses the vertical pressure borne by the shoe sole forming groove during the mold closing process and prevents the shoe sole size deviation caused by the deformation of the main mold frame 101. The support legs 202 lift the main mold frame 101 to form a bottom operating space, which facilitates the installation and debugging of the second cylinder 301 and the connecting frame 302 of the transmission mechanism 3. At the same time, it avoids the ground vibration from being transmitted to the mold and affecting the molding quality. The frame structure enhances the overall torsional resistance of the equipment and adapts to the inertial impact during high-speed mold changing.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4A first cylinder 203 is installed at the top axis of the base 201, and a plug-in block 204 is installed at the top output end of the first cylinder 203. The plug-in block 204 is vertically installed at the output end of the first cylinder 203 of the fixing mechanism 2. The plug-in block 204 is driven by the cylinder to rise and insert into the corresponding locking hole 106 at the bottom of the quick-change template 103, or to fall and disengage from the hole. The insertion of the plug-in block 204 and the locking hole 106 forms a vertical mechanical lock, which restricts the degree of freedom of template sliding, so that the target shoe sole mold groove is accurately located on the central axis of the processing area of ​​the main mold frame 101, avoiding the slight displacement of the template due to inertia after the cylinder drive stops. The plug-in locking mechanism is independent of the transmission mechanism 3 and can operate independently after the mold change is completed, ensuring that the position of the mold groove is not disturbed by external vibration during processing.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The quick-change template 103 has three locking holes 106 at its bottom, and the plug-in block 204 is used to plug into the locking holes 106, so that one of the bottom mold slots can be placed in the processing area of ​​the main mold frame 101. The three locking holes 106 at the bottom of the quick-change template 103 are strictly corresponding to the station spacing of the three shoe sole mold slots at the top. When the transmission mechanism 3 drives the template to slide and the target mold slot arrives at the processing area, the plug-in block 204 is inserted into the locking hole 106 corresponding to the slot. The lateral displacement of the template is eliminated by the hole-shaft cooperation. The design of the three holes covers all mold slot stations, ensuring that the processing center can be positioned by plugging and locking after any shoe type is changed, avoiding the offset of the shoe sole forming position caused by the cumulative error of the template length, and ensuring the consistency of the size of multiple batches of products.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4The second cylinder 301 of the transmission mechanism 3 drives the quick-release head 304 to move axially along the mounting rod 303, causing the quick-change template 103 to slide linearly along the dovetail slide rail 102, realizing the cyclic switching of the three shoe sole mold slots. When the target mold slot arrives at the processing area, the plug-in block 204 is simultaneously inserted into the corresponding locking socket 106 to complete the self-locking of the workstation. At the beginning stage of the sliding of the template by the second cylinder 301 of the transmission mechanism 3, the first cylinder 203 of the fixing mechanism 2 simultaneously controls the plug-in block 204 to descend and disengage from the current locking socket 106. The template constraint is released; when the target shoe sole mold groove slides to the processing area of ​​the main mold frame 101, the first cylinder 203 drives the plug block 204 to rise and insert into the corresponding locking socket 106 to complete the self-locking of the work station, and at the same time the second cylinder 301 stops outputting; the timing of the transmission and locking actions is linked by the control system to realize the continuous action of "unlocking during sliding and locking when in position", reducing the step-by-step operation time of "sliding stop and manual locking" in traditional mold changing, and the mechanical linkage mechanism reduces the complexity of electrical control and improves the reliability of the equipment.

[0038] See Figure 3 , Figure 4 The quick-change template 103 has detachable limit baffles 105 on both sides via bolts. The limit baffles 105 are used to constrain the sliding stroke of the quick-change template 103 and prevent the dovetail slide rail 102 from disengaging from the dovetail slide groove 104. The limit baffles 105 are detachably installed on both sides of the quick-change template 103 via bolts. The length of the baffles covers the start and end points of the template sliding path. When the template slides to the limit position of the stroke, the limit baffles 105 contact the end of the main mold frame 101 to prevent the template from continuing to move and prevent the dovetail slide groove 104 from disengaging from the dovetail slide rail 102. The baffles are connected by bolts for easy adjustment or replacement to adapt to the installation requirements of templates of different sizes. The mechanical limit design avoids guide rail derailment accidents caused by cylinder overtravel or sensor failure, ensuring the long-term stability and safety of the sliding mechanism.

[0039] The implementation principle of this embodiment is as follows: First, the second cylinder 301 of the transmission mechanism 3 is activated, and the connecting frame 302 is pushed through the output end to drive the mounting rod 303 to move axially, so that the quick-release head 304 fixed at the end of the mounting rod 303 drives the quick-change template 103 to slide linearly along the dovetail slide rail 102 of the main mold frame 101. The engagement structure between the dovetail slide groove 104 and the dovetail slide rail 102 provides directional guidance. At this time, the first cylinder 203 of the fixing mechanism 2 synchronously controls the insertion block 204 to descend, so that it disengages from the current locking insertion hole 106 and releases the position lock of the quick-change template 103.

[0040] When the target shoe sole mold groove moves to the center axis of the processing area of ​​the main mold frame 101, the first cylinder 203 drives the plug block 204 to rise and accurately insert it into the corresponding locking plug hole 106 at the bottom of the quick change template 103. The spacing of the three locking plug holes 106 matches the spacing of the mold groove station, realizing station self-locking; at the same time, the second cylinder 301 stops moving, so that the quick release head 304 keeps the quick change template 103 axially fixed by the bolt 305.

[0041] The limiting baffle 105 is fixed to both sides of the quick-change template 103 by bolts. During the sliding process, it restricts the template stroke, prevents the dovetail slide 104 from disengaging from the dovetail slide rail 102, and ensures sliding stability.
