Description

Technical Field

[0001] This utility model belongs to the field of shoe sole production technology, specifically relating to a shoe sole production equipment with multi-layer structure molding function. Background Technology

[0002] The construction of shoe soles is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole, and heel. In a narrow sense, it refers only to the outsole. Generally, the common characteristics of shoe sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, elastic, easy to fit the foot shape, not easy to deform after shaping, heat retention, and easy to absorb moisture. At the same time, it should work with the midsole to provide braking effect when changing feet to prevent slipping and to make it easy to stop.

[0003] The existing technology includes a multi-layer, multi-density shoe sole production mold with patent publication number CN216230489U. This patent uses three mold plates, each with injection molding grooves at both ends of its top. Different colored injection molding materials are then injected into two of the injection molding grooves on each of the three mold plates. After the injection molding materials have cooled for a period of time, a strong adhesive is applied to the top surface of the shoe sole formed inside the two injection molding grooves on the middle and bottom mold plates. Then, the piston rods of the second and third electric telescopic rods simultaneously apply a top force to four sliders, compressing the three mold plates together. However, in practical use, this production device still has the following shortcomings: From a practical point of view, this production device cannot produce shoe soles of different sizes and shapes. Different devices need to be replaced to produce different shoe soles, thereby increasing production costs and reducing the applicability of the device.

[0004] Therefore, there is a need for a shoe sole production equipment with multi-layer structure molding function to solve the problems of existing technology, such as the inability to produce shoe soles of different sizes and shapes, which increases production costs and reduces the applicability of the device.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figures 1-5This utility model provides a shoe sole production equipment with multi-layer structure forming function, including a support frame 1, a cylinder 2, a fixed column 3, an extrusion mechanism 4, a forming mechanism 5, and a first spring 6. The cylinder 2 is fixedly connected to the upper part of the support frame 1, the fixed column 3 is symmetrically fixedly connected to the left and right sides inside the support frame 1, the extrusion mechanism 4 is located below the cylinder 2, the forming mechanism 5 is located below the extrusion mechanism 4, and the first spring 6 is located between the forming mechanisms 5, and the first spring 6 is sleeved on the outside of the fixed column 3.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the extrusion mechanism 4 consists of a mounting plate 401, a push plate 403, a pressing plate 404, a second spring 405, a pressure block 406, a mounting block 407, a positioning block 409, and a third spring 410. The mounting plate 401 is fixedly connected to the output end of the cylinder 2. Grooves 402 are symmetrically opened on the left and right sides of the bottom surface of the mounting plate 401. Positioning grooves are symmetrically opened on the front and rear sides of the grooves 402. The push plate 403 is slidably connected to the inside of the positioning groove. The pressing plate 404 is fixedly connected to one end of the push plate 403. The second spring 405 is symmetrically fixedly connected between the pressing plate 404 and the outer surface of the mounting plate 401.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the mounting block 407 is fixedly connected to the top of the pressure block 406. The mounting block 407 is set inside the groove 402. The mounting block 407 has symmetrical expansion grooves 408 on the front and rear sides inside. The positioning block 409 is slidably connected to the inside of the expansion groove 408, and one end of the positioning block 409 extends out of the outer surface of the mounting block 407.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the third spring 410 is fixedly connected between the side of the positioning block 409 and the telescopic groove 408, and the size of the positioning block 409 is adapted to the positioning groove.

[0028] The new pressure block 406 is inserted into the groove 402 through the mounting block 407. The bottom surface of the groove 402 first contacts the arc surface of the positioning block 409 and is squeezed into the telescopic groove 408 until the positioning block 409 and the positioning groove are on the same horizontal line. Under the elastic action of the third spring 410, the positioning block 409 is driven to insert into the positioning groove, thus fixing the installation of the mounting block 407.

[0029] As can be seen from the above working process: by pressing the pressing plate 404 through the extrusion mechanism 4, the push plate 403 is moved, the positioning block 409 is released from fixing the mounting block 407, and the pressing block 406 and the mounting block 407 are quickly disassembled and assembled. The equipment can quickly replace the pressing block 406 of different specifications according to the production needs of different shoe soles, realize the production of shoe soles of different shapes and sizes, and meet the diversified needs of the market.

[0030] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that there are three molding mechanisms 5, arranged at the top, middle, and bottom. The lower molding mechanism 5 is fixedly connected to the bottom plate of the support frame 1. The molding mechanism 5 consists of a mold plate 501, an electric push rod 502, a baffle 503, a sliding plate 504, a mold body 505, a connecting block 506, a moving plate 508, a limiting block 509, and a fourth spring 511. The sliding plate 504 is symmetrically fixedly connected to the left and right sides of the mold plate 501, and the sliding plate 504 is slidably connected to the outside of the fixed column 3. The first spring 6 is fixedly connected between the two sliding plates 504. The electric push rod 502 is symmetrically fixedly connected to the bottom of the mold plate 501. The baffle 503 is fixedly connected to the extended end of the electric push rod 502, and the baffle 503 is slidably connected to the inside of the mold plate 501.

[0031] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the mold plate 501 has symmetrical openings inside that are adapted to the mold body 505. The left and right sides of the openings have symmetrical mounting grooves 507. The moving plate 508 is slidably connected to the inside of the mounting groove 507. The limiting block 509 is fixedly connected to one side of the moving plate 508. The fourth spring 511 is fixedly connected between the other side of the moving plate 508 and the side of the mounting groove 507. The connecting block 506 is symmetrically fixedly connected to the left and right sides of the mold body 505. The side of the connecting block 506 closest to the moving plate 508 has a limiting groove 510 adapted to the limiting block 509.

[0032] The new mold body 505 is inserted into the mounting groove 507 via the connecting block 506, which presses the inclined surface of the limiting block 509 until the limiting block 509 is reset under the elastic action of the fourth spring 511, so that the limiting block 509 is inserted into the limiting groove 510, thereby fixing the installation of the mold body 505.

[0033] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the top surface of the positioning block 409 has an arc-shaped surface, and the top surface of the limiting block 509 has an inclined surface.

[0034] This solution has the following working process: First, different colored injection molding materials are injected into the injection molding grooves of the six mold bodies 505. After the injection molding materials have cooled for a period of time, strong adhesive is applied to the top surface of the shoe sole formed inside the two injection molding grooves on the middle and bottom mold bodies 505. Then, the upper cylinder 2 is activated to move the mounting plate 401 downwards, causing the pressure block 406 to move and press down the upper and middle molding mechanisms 5, compressing the first spring 6 until the three molding mechanisms 5 are joined together. Then, the upper and middle electric push rods 502 are activated to move the baffle 503 towards the center, releasing the obstruction of the mold body 505. The cylinder 2 continues to be controlled to move the pressure block 406 downwards, squeezing the shoe sole inside the mold body 505, causing the multiple layers of shoe sole to bond together. Finally, the lower electric push rod 502 is controlled to move the baffle 503, and the pressure block 406 continues to move downwards, pushing the bonded multi-layer shoe sole out from under the lower molding mechanism 5, making it easy to remove the shoe sole.

[0035] When producing soles of different shapes, the pressure block 406 and the mold body 505 need to be replaced synchronously. First, press the pressing plates 404 on both the front and rear sides to move the push plate 403 towards the mounting block 407, release the positioning block 409 inserted in the positioning groove, and let the positioning block 409 retract into the telescopic groove 408. Thus, the mounting block 407 falls out of the groove 402, making it easy to replace the pressure block 406. The new pressure block 406 is inserted into the groove 402 through the mounting block 407. The bottom surface of the groove 402 first contacts the arc-shaped surface of the positioning block 409 and squeezes it into the telescopic groove 408 until the positioning block 409 and the positioning groove are on the same horizontal line. Under the elastic action of the third spring 410, the positioning block 409 is driven to insert into the positioning groove, fixing the installation of the mounting block 407. Then, the mold body 505 is replaced, and the two moving plates 508 are pushed in the opposite direction, causing the limiting block 509 to move and release the positioning of the connecting block 506, thereby removing the mold body 505. The new mold body 505 is inserted into the installation groove 507 through the connecting block 506, pressing the inclined surface of the limiting block 509 until the limiting block 509 is reset under the elastic action of the fourth spring 511, so that the limiting block 509 is inserted into the limiting groove 510, thereby fixing the installation of the mold body 505 and ensuring the stability of the multi-layer shoe sole pressure molding process.

[0036] In summary: The extrusion mechanism 4 presses the pressing plate 404, causing the push plate 403 to move, releasing the fixing of the positioning block 409 to the mounting block 407. This allows for rapid assembly and disassembly of the pressing block 406 and the mounting block 407. The equipment can quickly replace pressing blocks 406 of different specifications according to the production needs of different shoe soles, enabling the production of shoe soles of different shapes and sizes to meet diverse market demands. The forming mechanism 5 allows the mold body 505 to be fixed by the connecting block 506 and the limiting block 509 inside the mounting groove 507. The precise fit between the limiting block 509 and the limiting groove 510 ensures the accurate position of the mold body 505 on the mold plate 501, and allows for rapid replacement of the mold body 505. This significantly reduces downtime caused by changing production specifications, enabling the equipment to quickly switch between producing shoe soles of different specifications, improving production efficiency, and reducing production costs.
