Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment, and in particular to a sliding table type heel sleeve shaping machine. Background Technology

[0002] In footwear manufacturing, the heel sleeve molding process is a crucial step in production, directly impacting the comfort and durability of the shoes. Traditional heel sleeve molding equipment typically employs a fixed mold structure, using manual or mechanical pressing to achieve the molding process.

[0003] Specifically, the molds in heel sleeve molding equipment typically require manual intervention for alignment and separation. This not only increases the operational difficulty but also easily leads to product defects due to operational errors. Furthermore, the mold assembly and separation processes lack automated design, and the limited operating space makes it difficult to achieve rapid and continuous molding operations. These technical problems severely restrict the efficiency and product quality of heel sleeve molding processes, urgently requiring an innovative solution that can achieve precise alignment, automatic separation, and simplified operation procedures. Summary of the Invention

[0004] In view of the shortcomings mentioned above in the background technology, this utility model provides a sliding table type heel sleeve shaping machine.

[0005] The present invention adopts the following technical solution:

[0006] A sliding table type heel sleeve shaping machine, characterized in that the shaping machine comprises:

[0007] The workbench has an upper section divided into a pick-and-place area and a shaping area. A slide and a lifting seat are provided on the upper section of the workbench. The slide slides relative to the pick-and-place area and the shaping area. The lifting seat is located on the shaping area and moves vertically relative to the workbench.

[0008] The upper mold core is fixed under the lifting seat;

[0009] The lower mold core includes a left forming mold and a right forming mold, and a first elastic element is connected between the left forming mold and the right forming mold. The first elastic element provides an elastic force to push the left forming mold and the right forming mold apart relative to each other. When the left forming mold and the right forming mold move to close together, they form a shaping cavity for the heel sleeve. The shaping cavity is adapted to the upper mold core.

[0010] The guide has a tapered opening at one end facing outward from the worktable;

[0011] The slide table is provided with a clearance notch, and the bottom of the left forming mold and the right forming mold are both fixed with guide rods. The guide rods pass through the clearance notch to the bottom of the slide table. When the slide table moves to the shaping area, the two guide rods move inward along the inner side of the conical opening, so that the left forming mold and the right forming mold move relative to each other and come together, and the shaping cavity corresponds to the bottom of the upper mold core.

[0012] In one possible implementation, a crossbar is fixed on the slide, and the left and right forming dies are fitted outside the crossbar, thereby restricting the left and right forming dies to slide along the crossbar.

[0013] In one possible implementation, the slide is fixed with stop pins at positions opposite to the first elastic member on both the left and right forming molds, and the first elastic member pushes the left and right forming molds apart until they abut against the stop pins.

[0014] In one possible implementation, a slide rail is fixed on the worktable between the pick-up / placement area and the shaping area, and a slider is fixed at the bottom of the slide table, the slider being adapted to restrict sliding on the slide rail.

[0015] In one possible implementation, a first drive cylinder is fixed to the bottom of the slide, the first drive cylinder having a retractable piston rod, the end of the piston rod being fixed within one end of the shaping area of ​​the worktable.

[0016] In one possible implementation, the workbench is provided with a protective frame above the shaping area, the protective frame covers the shaping area, and a second drive cylinder is fixed to the top of the protective frame, the end of the piston rod of the second drive cylinder being fixed to the lifting seat.

[0017] In one possible implementation, the guide rod is a hollow tube, and a protruding contact point is provided at the bottom of the guide rod. The left forming mold and the right forming mold have built-in heating units, and the conductive wires of the heating units pass through the guide rod and are electrically connected to the contact point. Contact plates are fixed on both sides of the guide member within the conical opening, and both contact plates are electrically connected to a power source. When the slide moves to the shaping area, the contacts of the two guide rods move onto the two contact plates respectively.

[0018] In one possible implementation, a second elastic element is fixed to the bottom of the guide rod, the lower end of the second elastic element is fixed to the contact point, and the second elastic element provides an elastic force that pushes the contact point downwards toward the guide rod.

[0019] In one possible implementation, through slots are provided on both sides of the bottom of the guide rod, the second elastic element is a V-shaped spring sheet, the contact point is fixed to the bottom of the V-shaped spring sheet, and the two ends of the second elastic element extend to both sides to form limiting parts, and the two limiting parts are respectively adapted to pass through the two through slots.

[0020] In one possible implementation, a roller is provided at the lower end of the guide rod, and when the slide moves to the shaping area, the roller of the guide rod moves against the inner side of the conical opening.

[0021] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model achieves precise alignment and pressing of the lower mold core and the upper mold core through the cooperation of the slide table and the lifting seat, ensuring uniform force on the heel sleeve within the molding cavity and stable molding effect. During the movement of the slide table, the left and right molding molds automatically separate through the first elastic element. This design allows the left and right molding molds to automatically separate when the slide table moves out of the shaping area, facilitating the removal of the shaped heel sleeve and providing ample operating space for the next placement of the heel sleeve. Furthermore, the left and right molding molds achieve automatic closing through the tapered opening of the guide rod and guide element, quickly forming the shaping cavity without manual intervention, greatly simplifying the operation process and improving production efficiency.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0035] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0037] This utility model discloses a slide-table type 5 heel shaping machine, as shown in the attached figure. Figures 1 to 3 As shown, the shaping machine includes a worktable 1, an upper mold core 2, a lower mold core 3, and a guide component 4. The upper part of the worktable 1 is divided into a pick-and-place area 101 and a shaping area 102, and a slide table 5 and a lifting seat 6 are provided above the worktable 1. The lower mold core 3 is mounted on the slide table 5, and the slide table 5 slides relative to the pick-and-place area 101 and the shaping area 102.

[0038] The upper mold core 2 is fixed under the lifting seat 6, which is set on the shaping area 102 and moves vertically relative to the worktable 1. When the slide 5 moves into the shaping area 102, the lower mold core 3 is positioned below the upper mold core 2. After the lifting seat 6 descends, the upper mold core 2 is pressed into the forming cavity (not shown in the attached diagram) of the lower mold core 3 to press the heel sleeve placed in the forming cavity into shape. In addition, to improve the processing efficiency of the heel sleeve, the worktable 1 can be equipped with double slides 5 and double lifting seats 6, with multiple sets of lower mold cores 3 on each slide 5 and multiple upper mold cores 2 on the lifting seat 6, thereby enabling the simultaneous processing of multiple heel sleeves and improving the efficiency of hot pressing the heel sleeve.

[0039] As attached Figures 5 to 7 As shown, a first drive cylinder 51 is fixed to the bottom of the slide table 5. The first drive cylinder 51 has a piston rod that can move telescopically, and the end of the piston rod is fixed inside one end of the shaping area 102 of the worktable 1. The slide table 5 can be moved relative to the pick-up and place area 101 and the shaping area 102 by moving the telescopic rod of the first drive cylinder 51. Further, a slide rail 52 is fixed on the worktable 1 between the pick-up and place area 101 and the shaping area 102, and a slider 53 is fixed to the bottom of the slide table 5. The slider 53 is adapted to and restricted to slide on the slide rail 52, thereby restricting the smooth movement of the slide table 5 relative to the pick-up and place area 101 and the shaping area 102.

[0040] Continue to refer to the appendix Figure 2 and 3 A protective frame 11 is installed above the shaping area 102 on the workbench 1. The protective frame 11 covers the shaping area 102, and a second drive cylinder 61 is fixed to the top of the protective frame 11. The end of the piston rod of the second drive cylinder 61 is fixed to the lifting seat 6 to drive the upper mold core 2 to rise and fall. The second drive cylinder 61 is the same as the first drive cylinder 51, and can be a power actuator such as a cylinder with a piston rod, a hydraulic cylinder, or an electric push rod. Furthermore, a guide post 62 is fixed inside the protective frame 11. The guide post 62 is vertically arranged, and a linear bearing 63 is fixed to the lifting seat 6. The linear bearing 63 is adapted to fit outside the guide post 62, thereby restricting the smooth rise and fall of the lifting seat 6.

[0041] As attached Figure 9 As shown, the lower mold core 3 includes a left forming mold 31 and a right forming mold 32. Both the left and right forming molds 31 and 32 are equipped with heating units 36 for heating the heel sleeve. A crossbar 33 is also fixed on the slide table 5. Both the left and right forming molds 31 and 32 are provided with guide holes 331, which fit snugly against the crossbar 33, restricting the left and right forming molds 31 and 32 to slide relative to each other along the crossbar 33. The heating unit 36 ​​can be an electric heating element; refer to the attached diagram. Figure 11The left forming mold 31 and the right forming mold 32 are hollow inside, and the bottom of the left forming mold 31 and the right forming mold 32 are fixed to the base plate 37 by means of through screws. Both ends of the base plate 37 are fixed to the support 371. The two ends of the heating unit 36 ​​are respectively fixed to the two supports 371, and the heating unit 36 ​​is located above the guide hole 331 to avoid the space through which the crossbar 33 passes.

[0042] When the left forming mold 31 and the right forming mold 32 move to close together, the resulting groove portion becomes the shaping cavity. This shaping cavity is adapted to fit the upper mold core 2, causing the upper mold core 2 to press against the shaping cavity placed in the heel sleeve, thereby hot-pressing the heel sleeve. (See attached diagram.) Figure 10 A first elastic element 34 connects the left molding die 31 and the right molding die 32. The first elastic element 34 provides an elastic force that pushes the left molding die 31 and the right molding die 32 apart to widen the gap between them, facilitating the placement of the heel sleeve. Preferably, the first elastic element 34 can be a spring, and it is sleeved on the crossbar 33. In addition, the slide table 5 fixes stop pins 54 at positions where the left molding die 31 and the right molding die 32 face away from the first elastic element 34. After the first elastic element 34 pushes the left molding die 31 and the right molding die 32 apart, they are stopped by the stop pins 54, thus limiting the stroke of the left molding die 31 and the right molding die 32.

[0043] As attached Figure 7 As shown, the slide table 5 is provided with a clearance notch. Guide rods 35 are fixed to the bottom of both the left forming mold 31 and the right forming mold 32, and the guide rods 35 pass through the clearance notch to the bottom of the slide table 5. See also the attached diagram. Figure 5 and 6 The guide member 4 is fixed on the worktable 1 and located in the shaping area 102. The guide member 4 has a tapered opening 401 at one end facing outwards from the worktable 1, and the top of the guide member 4 is open. When the slide table 5 moves to the shaping area 102, the two guide rods 35 move inwards along the inner side of the tapered opening 401. The tapered opening 401 guides the guide rods 35, causing the left molding die 31 and the right molding die 32 to move relative to each other and merge to form a shaping cavity, which is located below the upper mold core 2. It can be seen that the movement of the slide table 5 allows the left molding die 31 and the right molding die 32 to move automatically to merge, eliminating the need for manual merging of the left and right molding dies 31, which is very convenient. When the slide table 5 moves from the shaping area 102 to the pick-and-place area 101, the guide rods 35 of the left molding mold 31 and the right molding mold 32 lose the restriction of the guide member 4, so that the first elastic member 34 pushes the left molding mold 31 and the right molding mold 32 apart, thereby widening the gap between the left molding mold 31 and the right molding mold 32 again, so as to facilitate the removal of the shaped heel sleeve and the placement of the heel sleeve again.

[0044] As attached Figure 8As shown, a roller 351 is provided on the lower end of the guide rod 35. The roller 351 can be a bearing, and the guide rod 35 is sleeved on the inner ring of the bearing. When the slide table 5 moves to the shaping area 102, the roller 351 of the guide rod 35 moves against the inner side of the conical opening 401. This structure can reduce the frictional force of the guide rod 35 moving relative to the side of the conical opening, making the closing of the left forming mold 31 and the right forming mold 32 more stable and smooth.

[0045] As attached Figure 12 As shown, the guide rod 35 is a hollow tube, and a protruding contact 71 is provided at the bottom of the guide rod 35. The conductive wires of the heating unit 36 ​​in the left forming mold 31 and the right forming mold 32 pass through the guide rod 35 and are electrically connected to the contact 71. Referring again to the attached figure, a second elastic member 73 is fixed to the bottom of the guide rod 35. The lower end of the second elastic member 73 is fixed to the contact 71. The second elastic member 73 provides an elastic force that pushes the contact 71 against the guide rod 35, so that the contact 71 automatically presses against the upper surface of the contact plate 72 after moving onto the contact plate 72. Preferably, the second elastic member 73 can be a V-shaped spring sheet, and the two ends of the second elastic member 73 extend to both sides to form limiting portions 731. The contact 71 can be fixed to the V-shaped spring sheet by direct welding or by screws. Both sides of the bottom of the guide rod 35 are provided with through slots 3501. The two limiting parts 731 of the second elastic member 73 are respectively adapted to pass through the two through slots 3501. The compression and expansion of the V-shaped spring sheet on both sides form an elastic force that pushes the contact point 71 down the guide rod 35.

[0046] Please refer to the appendix. Figure 6 The guide member 4 has copper contact plates 72 fixed on both sides within the conical opening 401. Both contact plates 72 are electrically connected to a power source, specifically, the contact plates 72 are connected to the mains power via conductive wires. When the slide table 5 moves to the shaping area 102, the contacts 71 of the two guide rods 35 move onto the two contact plates 72 respectively, so that the contacts 71 are energized by contact with the contact plates 72, and the current is transmitted to the heating unit 36, which converts electrical energy into heat energy, thereby heating the left forming mold 31 and the right forming mold 32, and further heating the heel sleeve placed on the forming cavity. This structure eliminates the need for the slide table 5 to drag the conductive wires connected to the heating unit 36 ​​during sliding, making the overall structure of the equipment simpler.

[0047] Preferably, the bottom surface of contact 71 can be a dome structure, so that after the bottom of contact 71 is blocked by the end of contact plate 72, it continues to be pressed against contact plate 72 as the slide table 5 moves, and rises onto contact plate 72, pressing against the upper surface of contact plate 72 to achieve a conductive connection between contact 71 and contact plate 72. In addition, the surface of contact plate 72 can be encapsulated with an insulating heat-shrink sleeve. This heat-shrink sleeve forms a through hole on the upper surface of contact plate 72, exposing a portion of the upper surface of contact plate 72. This exposed portion is used to contact contact 71. This structure of the heat-shrink sleeve can effectively protect contact plate 72.

[0048] In summary, this invention achieves precise alignment and pressing of the lower mold core 3 and the upper mold core 2 through the cooperation of the slide table 5 and the lifting seat 6, ensuring uniform force on the heel sleeve within the molding cavity and stable molding results. During the process, the left molding mold 31 and the right molding mold 32 automatically separate through the first elastic element 34. This design allows the left and right molding molds 32 to automatically separate when the slide table 5 moves out of the shaping area 102, facilitating the removal of the shaped heel sleeve and providing ample operating space for the next placement of the heel sleeve. Furthermore, the left molding mold 31 and the right molding mold 32 automatically close together through the guide rod 35 and the conical opening 401 of the guide element 4, quickly forming the shaping cavity without manual intervention, greatly simplifying the operation process and improving production efficiency. Furthermore, the heating unit 36 ​​is electrically connected to the contact plate 72 via the contact point 71 at the bottom of the guide rod 35, enabling automatic power supply and heating during the movement of the slide table 5. This avoids the cumbersome task of dragging conductive wires, making the equipment structure simpler and its operation more reliable. The overall design significantly reduces the difficulty of operation and maintenance costs, demonstrating high practicality and technical value.

[0049] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
