Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an elastic multi-pressure material position structure for shoe sole processing. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects; this tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. Often called the "mother of industry," steam pressure molding is used in shoe sole manufacturing to melt and extrude materials into shape.

[0003] Conventional autoclaving processes control the pressing position of the mold by moving the mold along its stroke. However, due to the different thicknesses of the forefoot and heel of the sole, the compression ratio of the forefoot is higher under the same pressing position. This results in a harder forefoot and lower elasticity in the autoclaved sole, leading to inconsistent quality and material waste, which in turn increases the production costs for manufacturers. Utility Model Content

[0004] The purpose of this utility model is to provide an elastic multi-pressure material position structure for shoe sole processing. By making the fixed mold core part into an elastic mold core, which is composed of multiple contour inserts, the pressure amount at different positions of the shoe sole can be easily controlled by adjusting the position of the contour inserts individually. This ensures that the compression ratio at different positions of the shoe sole is similar, thereby ensuring product quality and reducing production costs, thus solving the problems mentioned in the background art.

[0029] 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.

[0030] This utility model provides, for example Figures 1-10 The invention relates to an elastic multi-pressure material position structure for shoe sole processing, comprising a fixed mold base plate 1, a fixed mold frame 2 mounted on the top of the fixed mold base plate 1, a fixed pressure plate 3 fixedly mounted between the fixed mold base plate 1 and the fixed mold frame 2, a first contour insert 4 and a second contour insert 5 movably mounted on the top of the fixed pressure plate 3, the first contour insert 4 and the second contour insert extending into the inner cavity of the fixed mold frame 2, a support spring 6 fixed on the top of the fixed pressure plate 3, the top of the support spring 6 being fixed to the bottom of the first contour insert 4 and the second contour insert 5 respectively, and an adjustment component 7 for adjusting the first contour insert 4 and the second contour insert 5 provided on the fixed mold frame 2.

[0031] The first contour insert 4 and the second contour insert 5 are supported by the support spring 6, so that the first contour insert 4 and the second contour insert 5 extend into the fixed frame 22 of the fixed mold frame 2. Then, the height of the first contour insert 4 and the second contour insert 5 is adjusted by the limit screw 71 to adjust the pressing position, so as to ensure that the material compression ratio of different positions of the sole is similar, avoid the inconsistency of elasticity between the forefoot and the heel, effectively improve the quality of sole processing, and at the same time reduce the material of sole processing and reduce costs.

[0032] Among them, such as Figure 2 As shown:

[0033] Support columns 8 are fixedly connected around the top of the base plate 1. The top of the support columns 8 is fixed to the bottom of the base plate 2. The base plate 1 and the base plate 2 are fixedly connected by the support columns 8. At the same time, sufficient operating space is left between the base plate 2 and the base plate 1.

[0034] Furthermore, such as Figure 8 As shown:

[0035] The adjusting component 7 includes a limiting screw 71. A threaded hole 72 is provided on the top of the fixed mold frame 2. The limiting screw 71 is threaded into the threaded hole 72. The bottom of the limiting screw 71 passes through the fixed mold frame 2 and contacts the first contour insert 4 and the second contour insert 5 respectively. By rotating the limiting screw 71 in the threaded hole 72, it is convenient to adjust the length of the limiting screw 71 extending through the fixed mold frame 2 to the bottom. This facilitates the adjustment of the height at which the first contour insert 4 and the second contour insert 5 bounce under the support of the support spring 6, and allows for adjustment according to the compression ratio of different positions on the sole, so as to adjust the pressure position.

[0036] Preferred, such as Figure 7-9 As shown:

[0037] The first contour insert 4 and the second contour insert 5 both include an insert base 41 and a protrusion 42 located on the top of the insert base 41. The fixed mold frame 2 includes a fixed base 21 and a fixed frame 22 located on the top of the fixed base 21. The protrusion 42 extends into the inner cavity of the fixed frame 22 and fits against the inner wall. An insert top post 43 is fixed on the top of the insert base 41. The insert top post 43 passes through the fixed mold frame 2 and extends upward. By limiting the structure of the first contour insert 4, the second contour insert 5 and the fixed mold frame 2, it is convenient for the protrusions 42 of the first contour insert 4 and the second contour insert 5 to extend into the fixed frame 22 of the fixed mold frame 2. The fixed frame 22 is convenient for storing materials and for controlling and adjusting the pressing position.

[0038] It is worth noting that, such as Figure 9 As shown:

[0039] The top of the fixed pressure plate 3 is fixedly connected to the pressure plate positioning post 9, which is fixed to the bottom of the mold frame 2. The pressure plate positioning post 9 facilitates the fixing of the fixed pressure plate 3, so that the fixed pressure plate 3 and the mold frame 2 remain stable, so as to prevent the first contouring insert 4 and the second contouring insert 5 from moving relative to the mold frame 2, thereby causing the compression ratio of different positions of the shoe sole to change.

[0040] In a further preferred embodiment, such as Figure 7 As shown:

[0041] The top of the fixed mold frame 2 is threaded with a mounting screw 10. The mounting screw 10 passes through the fixed mold frame 2 and is threaded with an insert guide post 11. Both the insert base 41 and the fixed pressure plate 3 have through holes that align with the insert guide post 11. The insert guide post 11 is fixed by the mounting screw 10. Then, the insert guide post 11 passes through the through holes on the insert base 41 and the fixed pressure plate 3 in sequence to limit the first contour insert 4 and the second contour insert 5, so as to prevent the first contour insert 4 and the second contour insert 5 from shaking, and at the same time ensure that the first contour insert 4 and the second contour insert 5 move up and down smoothly.

[0042] In addition, such as Figure 1 , Figure 9 and Figure 10 As shown:

[0043] It also includes a moving mold frame 12 located above the fixed mold frame 2. The bottom of the moving mold frame 12 has a groove, and the fixed frame 22 is movably engaged in the groove. By setting the moving mold frame 12, it is convenient to use the moving mold frame 12 and the fixed mold frame 2 to steam press the material and process it into a shoe sole.

[0044] In this embodiment, as Figure 1-5 As shown:

[0045] Positioning rods 13 are installed around the top of the fixed mold frame 2. The positioning rods 13 pass through the moving mold frame 12 and extend upward. The positioning rods 13 installed on the top of the fixed mold frame 2 help to prevent misalignment and failure of mold closing when the moving mold frame 12 and the fixed mold frame 2 are closed.

[0046] The bottom of the insert base 41 and the top of the fixed pressure plate 3 are provided with a storage groove 14. The support spring 6 is located in the inner cavity of the storage groove 14. The storage groove 14 facilitates the storage of the support spring 6 and prevents the support spring 6 from being over-compressed and displaced when the first contour insert 4 and the second contour insert 5 are close to the fixed pressure plate 3, thus effectively ensuring the integrity and stability of the support spring 6.

[0047] Multiple sets of washers 15 are fitted on the limiting screw 71. The washers 15 are located above the fixed mold frame 2. By setting the washers 15, the stability between the limiting screw 71 and the fixed mold frame 2 is improved, and the limiting screw 71 is prevented from sliding.

[0048] In practical use, the limiting screw 71 is rotated so that it passes through the threaded hole 72 and contacts the first contour insert 4 and the second contour insert 5 respectively, thereby limiting and adjusting the height of the first contour insert 4 and the second contour insert 5. Under the support of the support spring 6, the first contour insert 4 and the second contour insert 5 move away from the fixed pressure plate 3 and extend into the fixed mold frame 2. At the same time, the insert top post 43 passes through the fixed mold frame 2 and extends upward, so that the pressing positions of the first contour insert 4 and the second contour insert 5 in the fixed frame 22 are different. The material is placed in the fixed frame 22, and then the moving mold frame 12 is pressed down to contact the fixed mold frame 2 to steam press the material. At the same time, the moving mold frame 12 squeezes the insert top post 43, so that the first contour insert 4 and the second contour insert 5 are reset to ensure that the compression ratio of the material is similar, effectively avoiding material waste, and ensuring the quality of the shoe sole.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
