Description

Technical Field

[0001] This utility model relates to the field of shoe sole pressing structure technology, specifically a shoe sole pressing mold structure. Background Technology

[0002] Rubber soles are shoe soles made of rubber. Their advantages lie in their softness, excellent elasticity, suitability for various sports, and shock absorption. Rubber soles are produced using a thermoforming process, where the rubber raw materials are placed into a thermoforming mold and melted at high temperatures to form the sole. After thermoforming, a small amount of rubber may remain at the edges of the sole, which operators need to remove using a trimming machine.

[0003] A Chinese patent document with publication number CN116494447B, entitled "Packaging Blind Box," mentions that it "includes a frame, and an upper mold and a lower mold mounted on the frame. The lower mold is provided with a vertical through groove, and an overflow groove is provided at the upper opening of the through groove. A bottom mold is slidably installed in the through groove and is installed at the working end of a second linear driver. After the upper mold and the lower mold are closed, the second linear driver drives the bottom mold and the upper mold to move vertically in the through groove. A ring cutter is sleeved on the upper mold and is elastically connected to the frame through a mounting base. A locking unit is provided on the upper side of the lower mold. This technical solution, by setting a ring cutter on the upper mold, cooperating with the locking unit to lock the position of the ring cutter, and with the movable upper and bottom molds, enables the separate cutting of waste generated in each molding process during the molding of two-color shoe soles, facilitating the classification and collection of waste."

[0004] The aforementioned patent has certain shortcomings in its use. Existing pressing molds require manual cutting of rubber raw materials for feeding, which cannot guarantee the accuracy of feeding and affects the rubber feeding rate, thereby affecting the production efficiency of shoe sole pressing. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a shoe sole pressing mold structure. This structure includes a support platform, a cutting cylinder, a cutting blade, a weighing hopper, an unloading cylinder, a weighing sensor, a servo motor, a reduction gearbox, and a conveying roller. The servo motor, after being decelerated by the reduction gearbox, drives the conveying roller to rotate, thus precisely conveying the rubber strip material to the underside of the cutting blade. This allows for precise control of the conveying length of the rubber strip, ensuring accurate cutting and material preparation. The cutting cylinder pushes the cutting blade downwards to cut the rubber strip material. The cut rubber strip falls into the weighing hopper, where the weighing sensor automatically weighs and verifies the weight. Based on the verified weight, the conveying distance of the conveying roller can be precisely adjusted for the next cut, ensuring the accuracy of the next cut and improving the cutting speed and accuracy of the rubber strip material. This effectively solves the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shoe sole pressing mold structure, including a lower mold, an upper mold hinged to one side of the lower mold, a support platform on the other side of the lower mold, a cutting cylinder on the upper part of the support platform, a cutting blade fixedly connected to the telescopic end of the lower part of the cutting cylinder, a weighing hopper on the inclined surface of the support platform, a weighing sensor on the lower side of the weighing hopper, a base plate fixedly connected to the lower side of the weighing sensor, a discharge cylinder connected to the vertical side of the base plate, a reduction gearbox on one side of the upper part of the support platform, a servo motor connected to the upper side of the reduction gearbox, a conveying roller connected to the output end of the reduction gearbox, and a sliding roller that can be provided on the upper side of the support platform to facilitate the stable movement of the rubber strip during the rolling conveying of the conveying roller.

[0007] Furthermore, a limit pin is welded to the side of the lower mold away from the hinge position with the upper mold, and a molding heating plate is installed on the opposite side of the lower mold and the upper mold. The molding heating plate can heat and mold the rubber raw material, so that the rubber raw material completes the molding operation.

[0008] Furthermore, a limiting arc plate is provided on the side of the upper mold away from the hinge position with the lower mold. A handle is fixedly connected to the limiting arc plate. The limiting arc plate can be locked onto the limiting pin by the handle, thereby making the upper mold and the lower mold firmly closed, preventing the rubber raw material from opening the upper mold and the lower mold during heating and molding, and ensuring the safety of the pressing operation.

[0009] Furthermore, a hinge seat is fixedly connected to the side of the upper mold away from the forming heating plate, and a mold closing cylinder is connected to the hinge seat. A side bracket is connected to the end of the mold closing cylinder away from the hinge seat. The side bracket can provide stable support for the mold closing cylinder, ensuring that the mold closing cylinder stably presses the upper mold onto the lower mold, thus ensuring the mold closing effect.

[0010] Furthermore, a base box is provided under the lower mold and the side support. The weighing hopper moves horizontally. Anti-slip protrusions are formed on the outer ring side of the conveying roller. The anti-slip protrusions on the outer side of the conveying roller can stably press against the rubber strip material. The rotating conveying roller can stably convey the rubber strip to the cutting blade at the lower side, so that the cutting blade can perform cutting processing. After the rubber strip is loaded into the weighing hopper, the weighing sensor can weigh the rubber strip material, so as to accurately verify the weight of the rubber strip material and ensure that the conveying and cutting of the rubber strip is more accurate in the next time.

[0011] Furthermore, the mold-closing cylinder is hinged to the side support, and the mold-closing cylinder is hinged to the hinge seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a support platform, cutting cylinder, cutting blade, weighing hopper, unloading cylinder, weighing sensor, servo motor, reduction gearbox, and conveying roller, enables the servo motor to drive the conveying roller to rotate after being decelerated by the reduction gearbox, thereby accurately conveying the rubber strip raw material to the underside of the cutting blade. This allows for precise control of the conveying length of the rubber strip, thus ensuring the accuracy of rubber strip cutting. The cutting cylinder pushes the cutting blade downward to cut the rubber strip raw material. The cut rubber strip falls into the weighing hopper, and the weighing sensor automatically weighs and verifies the weight of the rubber strip. Based on the verified weight, the conveying distance of the conveying roller can be precisely adjusted for the next cut, ensuring the accuracy of the next cut and improving the cutting speed and accuracy of the rubber strip raw material.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 Example 1: This example provides a technical solution: a shoe sole pressing mold structure, including a lower mold 2, an upper mold 3 hinged to one side of the lower mold 2, a support platform 11 on the other side of the lower mold 2, a cutting cylinder 14 on the upper part of the support platform 11, a cutting blade 15 fixedly connected to the telescopic end of the lower part of the cutting cylinder 14, a weighing hopper 17 on the inclined surface of the support platform 11, a weighing sensor 19 on the lower side of the weighing hopper 17, a base plate fixedly connected to the lower side of the weighing sensor 19, a discharge cylinder 18 connected to the vertical side of the base plate, a reduction gearbox 13 on one side of the upper part of the support platform 11, a servo motor 12 connected to the upper side of the reduction gearbox 13, and a conveying roller 16 connected to the output end of the reduction gearbox 13.

[0022] Example 2: The fundamental difference between this example and Example 1 is that a support roller is provided on the upper side of the support platform 11 in this example. When the conveying roller 16 rotates and drives the rubber strip to move, the support roller can reduce the sliding friction on the lower side of the rubber strip, thereby ensuring the conveying efficiency of the rubber strip and enabling the cutting equipment to effectively cut the rubber strip. This example includes a lower mold 2, an upper mold 3 is hinged to one side of the lower mold 2, and a support platform 11 is provided on the other side of the lower mold 2. A cutting cylinder 14 is provided on the upper part of the support platform 11, and a cutting blade 15 is fixedly connected to the telescopic end of the lower part of the cutting cylinder 14. A weighing hopper 17 is provided on the inclined surface of the support platform 11, a weighing sensor 19 is provided on the lower side of the weighing hopper 17, a base plate is fixedly connected to the lower side of the weighing sensor 19, and a discharge cylinder 18 is connected to the vertical side of the base plate. A reduction gearbox 13 is provided on one side of the upper part of the support platform 11, a servo motor 12 is connected to the upper side of the reduction gearbox 13, and a conveying roller 16 is connected to the output end of the reduction gearbox 13.

[0023] Example 3: The fundamental difference between this example and Example 1 is that there are two weighing hoppers 17 arranged side by side in this example. The two weighing hoppers 17 are used in a cycle. One weighs the material, and the other pushes the weighed rubber strip material out of the mold, which improves the feeding efficiency of the pressing mold. This example includes a lower mold 2. The upper mold 3 is hinged to one side of the lower mold 2. A support platform 11 is set on the other side of the lower mold 2. A cutting cylinder 14 is set on the upper part of the support platform 11. A cutting blade 15 is fixedly connected to the telescopic end of the lower part of the cutting cylinder 14. The weighing hopper 17 is set on the inclined surface of the support platform 11. A weighing sensor 19 is set on the lower side of the weighing hopper 17. A base plate is fixedly connected to the lower side of the weighing sensor 19. A discharge cylinder 18 is connected to the vertical side of the base plate. A reduction gearbox 13 is set on one side of the upper part of the support platform 11. A servo motor 12 is connected to the upper side of the reduction gearbox 13. A conveying roller 16 is connected to the output end of the reduction gearbox 13.

[0024] A limiting pin 5 is welded to the side of the lower mold 2 away from the hinge position with the upper mold 3. A forming heating plate 4 is installed on the opposite side of the lower mold 2 and the upper mold 3. The limiting pin 5 can be clamped by the limiting arc plate 6, so that the upper mold 3 and the lower mold 2 are firmly connected, and the hot pressing of the rubber strip after the mold is closed will not open the mold, thus ensuring the safety of the forming process.

[0025] A limiting arc plate 6 is provided on the side of the upper mold 3 away from the hinge position with the lower mold 2. A handle 7 is fixedly connected to the limiting arc plate 6. The handle 7 is provided to facilitate the rotation of the limiting arc plate 6, thereby facilitating the clamping of the limiting arc plate 6 onto the limiting pin 5.

[0026] A hinge seat 10 is fixedly connected to the side of the upper mold 3 away from the forming heating plate 4. A mold closing cylinder 8 is connected to the hinge seat 10. A side bracket 9 is connected to the end of the mold closing cylinder 8 away from the hinge seat 10. The mold closing cylinder 8 provides power for the closing and opening of the upper mold 3, ensuring the tightness of the upper mold 3 when closing downward.

[0027] The lower mold 2 and the side support 9 are provided with a bottom box 1. The weighing hopper 17 moves horizontally. The outer ring of the conveying roller 16 is formed with anti-slip protrusions. The bottom box 1 provides stable support for the side support 9 and the mold equipment on the upper side, ensuring the overall stable operation of the closed equipment.

[0028] The mold closing cylinder 8 is hinged to the side support 9, and the mold closing cylinder 8 is hinged to the hinge seat 10.

[0029] The key design features of this utility model are:

[0030] 1. The utility model, through the setting of a support platform 11, a cutting cylinder 14, a cutting blade 15, a weighing hopper 17, a discharge cylinder 18, a weighing sensor 19, a servo motor 12, a reduction gearbox 13, and a conveying roller 16, enables the servo motor 12 to drive the conveying roller 16 to rotate after being reduced in speed by the reduction gearbox 13, thereby accurately conveying the rubber strip raw material to the underside of the cutting blade 15, so that the conveying length of the rubber strip is precisely controlled, thus ensuring the accuracy of rubber strip cutting. The cutting cylinder 14 pushes the cutting blade 15 to move downward, thereby cutting the rubber strip raw material. The cut rubber strip falls into the weighing hopper 17, and the weighing sensor 19 automatically weighs and verifies the weight of the rubber strip. Based on the verified weight, the conveying distance of the conveying roller 16 can be precisely adjusted for the next time, ensuring the accuracy of the next rubber strip cutting, and improving the cutting speed and accuracy of rubber strip raw material.

[0031] The operation process of the shoe sole pressing mold structure provided by this utility model is as follows: Figures 1-5 As shown, during use, the upper mold 3 is opened by the mold closing cylinder 8. The servo motor 12 drives the conveying roller 16 to rotate after being reduced in speed by the reduction gearbox 13, thereby accurately conveying the rubber strip material to the lower side of the cutting blade 15, so that the conveying length of the rubber strip is accurately controlled, thus ensuring the accuracy of the rubber strip cutting. The cutting cylinder 14 pushes the cutting blade 15 to move downward, thereby cutting the rubber strip material. The cut rubber strip falls into the weighing hopper 17. The weight of the rubber strip is automatically weighed and verified by the weighing sensor 19. The conveying distance of the conveying roller 16 can be accurately adjusted according to the verified weight to ensure the accuracy of the next cutting of the rubber strip. The rubber strip in the weighing hopper 17 is pushed out by the unloading cylinder 18 and falls into the forming groove of the forming heating plate 4. The rubber strip is manually placed in position, and then the mold closing cylinder 8 pushes the upper mold 3 to rotate downward to close the mold. After the mold is closed, it is heated and formed, completing the pressing operation.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
