Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically a high-efficiency stamping shoe die. Background Technology

[0002] In the footwear industry, the sole is a core component of shoes, and its molding quality and production efficiency directly affect the overall quality of shoes and the production benefits of enterprises. In the sole molding process, stamping molds are the key equipment to achieve precise control of the shape and size of the sole. By extruding and shaping raw materials such as rubber and plastic through molds, sole products that meet design requirements can be obtained quickly. They are widely used in the large-scale production of various footwear such as casual shoes, sports shoes, and work shoes. Currently, most mainstream shoe sole stamping dies on the market adopt a basic structure of "fixed lower die + movable upper die". The upper die is lifted and stamped by hydraulic or pneumatic drive mechanism. Specifically, in the existing technology, the operator first needs to manually lay the shoe sole material in the cavity of the fixed lower die, and then start the drive mechanism to drive the upper die to squeeze the material downward. After the material is formed, the drive mechanism drives the upper die to rise, and then the operator manually takes the formed shoe sole out of the lower die to complete a single stamping process.

[0003] After the stamping and pressure holding are completed, the drive mechanism drives the upper mold to rise back to the initial position. At this time, the material removal operation needs to be completed manually or mechanically. When removing the material manually, the staff needs to hold a tool and reach into the gap of the mold to remove the formed shoe sole from the lower mold cavity. Mechanical material removal usually adopts a cylinder-driven gripper or suction cup structure. The gripper is triggered by a preset program to clamp or the suction cup is activated to remove the shoe sole from the mold. However, existing shoe sole stamping dies have shortcomings in practical applications: Manual material handling is inefficient and unstable. It requires workers to wait for the upper mold to fully recover before they can handle the material handling. Manual operation is susceptible to factors such as fatigue and lack of experience, which may result in problems such as scratching the sole surface or leaving residual material in the mold cavity during material handling. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a high-efficiency stamping shoe mold, which solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency stamping shoe mold, comprising a base, a support leg fixedly connected to the top of the base in a symmetrical structure, a bottom plate provided on the top of the support leg, support frames provided on both sides of the bottom plate, an electric telescopic rod fixedly connected to the top of the support frame, an extrusion mold connected to the output end of the electric telescopic rod, a movable mold rotatably connected to both sides of the top of the bottom plate, gears sleeved at the pivots at both ends of the movable mold, connecting blocks fixedly connected to both sides of the movable mold in a symmetrical structure, a rack fixedly installed on the outer side of the connecting block, the rack meshing with the gear, and a collection box for use with the movable mold provided on the top of the base in a symmetrical structure.

[0006] As a further embodiment of this utility model: multiple protrusions are provided on the outer side of the extrusion mold, a fixing rod is fixedly connected to the top outer side of the base plate, the protrusions are slidably connected to the fixing rod, and a limiting groove is provided on the inner side of the fixing rod to cooperate with the protrusions.

[0007] As a further embodiment of this utility model: a protective shell is snapped onto the outer side of the fixing rod, and the rack and the gear are located inside the protective shell.

[0008] As a further embodiment of this utility model: the bottom of the protective shell is provided with a groove for use with the rack.

[0009] As a further embodiment of this utility model: a groove is provided on the outer side of the protective shell to cooperate with the connecting block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of electric telescopic rod drive and gear rack transmission, the automatic reset and automatic unloading of the movable mold are realized: when the extrusion mold moves down, the rack and gear can be rotated by pushing the connecting block, so that the movable mold can automatically reset to a flat state. After extrusion molding, the extrusion mold rises to the top, and the rack moves in the opposite direction to drive the movable mold to flip outward to unload the material. The whole process does not require the staff to manually adjust the mold position or remove the material from the mold. This not only reduces the number of manual intervention steps, but also avoids the deformation and scratches caused by manual material removal to the sole. It is especially suitable for mass production scenarios, reducing the intensity of operation while improving the safety of operation. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figures 1-5 As shown, this utility model provides a technical solution: A high-efficiency stamping shoe mold includes a base 1, with supporting legs 2 fixedly connected to the top of the base 1 in a symmetrical structure. A base plate 3 is provided on the top of the supporting legs 2. Support frames 13 are provided on both sides of the base plate 3. An electric telescopic rod 4 is fixedly connected to the top of the support frame 13. An extrusion mold 5 is connected to the output end of the electric telescopic rod 4. Movable molds 10 are rotatably connected to the top of the base plate 3. Gears 11 are sleeved at the pivots at both ends of the movable mold 10. Connecting blocks 6 are fixedly connected to both sides of the movable mold 10 in a symmetrical structure. A rack 7 is fixedly installed on the outside of the connecting blocks 6. The rack 7 meshes with the gear 11. A collection box 12 for use with the movable mold 10 is provided on the top of the base 1 in a symmetrical structure. Specifically, when in use, the equipment initialization program is started first. At this time, the electric telescopic rod 4 at the top of the support frame 13 will drive the extrusion mold 5 to move downward. During the process, the extrusion mold 5 will push the connecting blocks 6 on both sides, so that the rack 7 fixed on the outside of the connecting block 6 moves synchronously. Since the rack 7 and the gear 11 at the two ends of the movable mold 10 mesh with each other, the movement of the rack 7 will drive the gear 11 to rotate, thereby causing the movable mold 10, which was originally in the flipped state, to gradually rotate and reset until the two movable molds 10 together form a flat mold bottom surface. After the movable mold 10 is completely flat, the staff or automatic feeding mechanism will evenly spread the shoe sole material on the flat surface formed by the movable mold 10 to complete the feeding operation. Then the electric telescopic rod 4 will continue to drive the extrusion mold 5 to press downward. The extrusion mold 5 cooperates with the movable mold 10 in the flat state to stamp and form the material, ensuring that the shoe sole reaches the preset shape and thickness. After the sole is extruded and formed, the electric telescopic rod 4 drives the extrusion mold 5 to rise upward until it reaches the highest position set by the equipment. During this process, the pushing force of the extrusion mold 5 on the connecting block 6 disappears. The gear 7 and gear 11 mesh again to drive the movable molds 10 on both sides to gradually flip outward, so that the formed sole loses support and falls naturally into the collection box 12 symmetrically set on the top of the base 1, completing the unloading. Then the equipment can enter the next cycle process. The outer side of the extrusion die 5 is provided with multiple protrusions 15, and the top outer side of the base plate 3 is fixedly connected with a fixing rod 16. The protrusions 15 and the fixing rod 16 are slidably connected. The inner side of the fixing rod 16 is provided with a limiting groove 17 that is used to cooperate with the protrusions 15. The outer side of the fixing rod 16 is snapped with a protective shell 8. The rack 7 and the gear 11 are located inside the protective shell 8. The bottom of the protective shell 8 is provided with a slot 9 that is used to cooperate with the rack 7. The outer side of the protective shell 8 is provided with a sliding groove 14 that is used to cooperate with the connecting block 6. Specifically, when the electric telescopic rod 4 drives the extrusion mold 5 to move up and down, the multiple protrusions 15 on the outer side of the extrusion mold 5 will slide synchronously along the fixed rod 16 fixed on the outer side of the top of the base plate 3, and the protrusions 15 are always stuck in the limiting groove 17 on the inner side of the fixed rod 16. During the process of the extrusion mold 5 extruding raw materials downward or rising upward, the cooperation between the protrusions 15 and the fixed rod 16 and the limiting groove 17 provides stable guidance for the movement of the extrusion mold 5, and avoids it from deviating or shaking. Meanwhile, the protective shell 8 is installed on the outside of the fixed rod 16 by a snap fastener. When the connecting block 6 moves the rack 7 in conjunction with the extrusion mold 5, the rack 7 will slide along the slot 9 at the bottom of the protective shell 8, and the connecting block 6 will move synchronously in the sliding groove 14 on the outside of the protective shell 8. The protective shell 8 provides protection for the transmission parts of the rack 7, gear 11 and connecting block 6 throughout the process. During use, the cooperation of the protrusion 15 with the fixing rod 16 and the limiting groove 17 ensures the accuracy of the movement of the extrusion mold 5, thereby ensuring the dimensional accuracy of the shoe sole stamping and reducing product defects caused by mold offset. The protective shell 8 can effectively prevent raw material debris, dust and other materials generated during the production process from entering the transmission parts of the rack 7 and gear 11, avoiding impurities from affecting the meshing transmission effect of the gear 11 and rack 7, reducing component wear, extending the service life of the mold, and also preventing workers from accidentally touching the transmission parts during operation, thus improving the safety of use. The working principle of this utility model is as follows: First, after the equipment starts the initialization program, the electric telescopic rod 4 at the top of the support frame 13, as the core power component, will drive the extrusion mold 5 to move downward. During this process, the extrusion mold 5 will push the connecting blocks 6 on both sides, causing the rack 7 fixed on the outside of the connecting blocks 6 to move synchronously. Since the rack 7 meshes with the gears 11 at the two ends of the movable mold 10, the linear movement of the rack 7 will be converted into the rotational movement of the gears 11, which will then drive the movable mold 10, which was originally in a flipped state, to gradually rotate and reset, so that the two movable molds 10 together form a flat mold bottom surface, which is ready for subsequent feeding and stamping. Secondly, after the movable mold 10 is completely flat, the staff or automatic feeding mechanism lays the shoe sole material on the flat surface of the movable mold 10. After the feeding is completed, the electric telescopic rod 4 continues to drive the extrusion mold 5 to move downward. At this time, the extrusion mold 5 and the flat movable mold 10 form a closed mold space. Through the pressure of the extrusion mold 5, the material is stamped and formed to ensure that the shoe sole reaches the preset shape and thickness. After the forming is completed, the electric telescopic rod 4 runs in the opposite direction, driving the extrusion mold 5 to rise back to the top position set by the equipment. During this process, the pushing force of the extrusion mold 5 on the connecting block 6 disappears. The rack 7 and gear 11 are meshed and driven again, driving the movable molds 10 on both sides to gradually flip outward. The formed shoe sole loses support and falls naturally into the collection box 12 symmetrically set on the top of the base 1, completing the unloading process. The equipment can then enter the next cycle. It is worth mentioning that during the entire process of the extrusion die 5 moving up and down, the multiple protrusions 15 on its outer side will form a sliding engagement with the fixing rod 16 fixed on the outer side of the top of the base plate 3, and the protrusions 15 are always stuck in the limiting groove 17 on the inner side of the fixing rod 16; this structure can provide precise guidance for the movement of the extrusion die 5, effectively preventing the extrusion die 5 from shifting or shaking during the stamping or lifting process, thereby ensuring the dimensional accuracy of the shoe sole stamping and reducing product defects caused by die position deviation; Finally, when the connecting block 6 moves in conjunction with the extrusion die 5 to drive the rack 7, the rack 7 can slide along the slot 9 at the bottom of the protective shell 8, and the connecting block 6 can move synchronously in the sliding groove 14 on the outside of the protective shell 8. This does not affect the normal operation of the transmission components, and the protective shell 8 can block the raw material debris, dust and other impurities generated during the production process from entering the transmission parts of the rack 7 and the gear 11, thus avoiding impurities from interfering with the meshing transmission effect, reducing component wear, and extending the service life of the die.

[0015] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
