Description

TECHNICAL FIELD

[0001] The present application relates to the field of shoe sole manufacturing, in particular to a mold for integrally forming a shoe sole. BACKGROUND

[0002] In the shoe manufacturing industry, especially in the field of sports shoe manufacturing, ETPU is widely used due to its excellent elasticity and comfort. The traditional ETPU shoe sole manufacturing method usually involves compounding the ETPU midsole and the bottom sheet through gluing. However, this method has many shortcomings, such as low production efficiency, high labor intensity, and environmental pollution caused by the use of a large amount of glue. In recent years, in order to improve production efficiency and reduce environmental pollution, more and more enterprises have begun to use integrally forming process to manufacture ETPU shoe sole. This process not only simplifies the production process, but also significantly improves the production efficiency.

[0003] In the existing integrally forming process of ETPU shoe sole, the common method is to pre-lay the bottom sheet in the forming mold, then inject ETPU foaming particles into the forming cavity for heating and expansion, and finally form an integrated shoe sole.

[0004] However, part of the bottom sheet is hollow or divided into multiple parts attached to the midsole. When ETPU foaming particles are injected into the inside of the forming cavity, the ETPU foaming particles will extrude the bottom sheet, causing the bottom sheet to deviate, resulting in a decrease in the yield of the produced shoe sole. CONTENT OF THE INVENTION

[0005] In order to improve the yield of the produced shoe sole, the present application provides a mold for integrally forming a shoe sole.

[0006] The mold for integrally forming a shoe sole provided by the present application adopts the following technical solution:

[0008] By adopting the above technical scheme, after the bottom plate is placed inside the forming cavity, the driving part drives the negative pressure block to abut against the fixed die, and then the air suction pump is started. The air suction pump extracts the air inside the negative pressure groove to form negative pressure, and the pressure difference between the forming cavity and the negative pressure groove is formed, so that the bottom plate is conveniently adsorbed to the inner wall of the forming cavity close to the negative pressure block for fixation. When the ETPU foaming particles are injected into the forming cavity, the bottom plate is fixed by being adsorbed to the inner wall of the forming cavity, so that the condition that the bottom plate is deviated due to extrusion of the ETPU foaming particles is reduced, and the yield of the production shoe sole is improved.

[0009] Meanwhile, the mold for the ETPU foaming particles of the present application itself needs to be provided with a first exhaust hole for discharging steam, that is, the modification of the original mold in the present application is to increase a support frame, a driving part and a negative pressure block outside, and the improvement of the present application is suitable for molds of different sizes.

[0011] By adopting the above technical scheme, when the movable die and the fixed die are closed, the movable shielding cover and the fixed shielding cover abut against each other, so as to wrap the movable die and the fixed die. When steam is introduced into the forming cavity for heating, the steam is discharged from the first exhaust hole, and the movable shielding cover and the fixed shielding cover shield the steam, so as to reduce the condition that the steam sprayed from the first exhaust hole injures the workers.

[0013] By adopting the above technical scheme, after the ETPU foaming particles inside the forming cavity are heated, water is sprayed to the movable die and the fixed die through the first cooling pipe and the second cooling pipe for cooling, so as to accelerate the cooling of the ETPU foaming particles to form the midsole.

[0014] Optionally, the side of the fixed die away from the movable die is fixedly installed with a sealing strip, and the sealing strip is used for sealing when the negative pressure block and the fixed die abut against each other.

[0018] Optionally, the inner bottom wall of the negative pressure groove is provided with a shielding block, and the shielding block abuts against the fixed mold when the negative pressure block abuts against the fixed mold.

[0019] By adopting the above technical scheme, for the bottom sheet with hollow or multiple pieces, the bottom sheet does not completely cover the bottom side of the midsole, and the bottom sheet also does not completely cover the inner wall of the forming cavity close to the negative pressure block.

[0035] The following will be described in detail in combination with the accompanying drawings. Figures 1-7 The present application will be further described in detail.

[0036] Embodiment 1.

[0037] The embodiment of the present application discloses a mold for integrally forming a shoe sole.

[0038] Reference will be made to Figure 1 , Figure 2The utility model provides a mould for sole integrated forming, including movable mould 1 and fixed mould 2. Forming cavity 3 is formed between movable mould 1 and fixed mould 2. Movable mould 1 is provided with feed inlet and air inlet that communicate with forming cavity 3, and ETPU foaming particles are injected into forming cavity 3 through feed inlet. Steam that heats ETPU foaming particles is injected into forming cavity 3 from air inlet. Fixed mould 2 is provided with first exhaust hole 4 that communicates with forming cavity 3, and steam is discharged from first exhaust hole 4 after heating ETPU foaming particles.

[0039] Referring to Figure 2 、 Figure 3 Movable mould 1 and fixed mould 2 are fixedly installed with support frame 5 on the side away from each other, and drive element 6 is fixedly installed on the support frame 5 of fixed mould 2, which is a pneumatic cylinder or a lead screw, and is a pneumatic cylinder in the embodiment. Drive element 6 is fixedly installed with negative pressure block 7, and negative pressure groove 8 and communication groove 9 are formed on the side close to fixed mould 2. The number of negative pressure groove 8 and forming cavity 3 is equal, and negative pressure groove 8 and forming cavity 3 are arranged one by one. In the embodiment, there are two negative pressure grooves 8 and forming cavities 3. Each negative pressure groove 8 is communicated with communication groove 9, and second exhaust hole 10 is formed on the inner wall of communication groove 9. Negative pressure block 7 is installed with air suction pump, and the air inlet end of air suction pump is communicated with second exhaust hole 10.

[0040] After the bottom sheet is placed into forming cavity 3, and before ETPU foaming particles are injected into forming cavity 3, drive element 6 drives negative pressure block 7 to abut against the side of fixed mould 2 away from movable mould 1, and each first exhaust hole 4 on fixed mould 2 is located at the position where negative pressure groove 8 covers fixed mould 2. Then air suction pump is started to extract air in negative pressure groove 8, and the amount of air in forming cavity 3 entering negative pressure groove 8 from first exhaust hole 4 is less than the amount of air extracted from negative pressure groove 8 by air suction pump, so that a pressure difference is formed between negative pressure groove 8 and forming cavity 3, and then the bottom sheet is tightly abutted against the inner wall of forming cavity 3 close to negative pressure block 7.

[0041] When ETPU foaming particles are injected into forming cavity 3, the bottom sheet is tightly abutted against the inner wall of forming cavity 3 close to negative pressure block 7, so that the case that ETPU foaming particles push the bottom sheet to move is reduced, and the yield of sole production is improved.

[0042] After ETPU foaming particles are injected into forming cavity 3, steam needs to be introduced into forming cavity 3 for heating, and drive element 6 drives negative pressure block 7 to move away from fixed mould 2. The bottom sheet is provided with a hole in advance, and the part of the hole provided in advance on the bottom sheet coincides with first exhaust hole 4 after the bottom sheet is placed into forming cavity 3, so that steam is discharged from first exhaust hole 4 after heating ETPU foaming particles. At the same time, part of the melted ETPU foaming particles enters the hole provided in advance on the bottom sheet, and the connection strength between the midsole and the bottom sheet is improved when the ETPU foaming particles cool and solidify to form the midsole.

[0043] Referring to Figure 2 , Figure 3 , the inner bottom wall of the negative pressure groove 8 is provided with a shielding block 11. When the negative pressure block 7 abuts against the fixed mold 2, the shielding block 11 abuts against the fixed mold 2. Part of the bottom sheet is hollowed out or a plurality of bottom sheets are installed on the middle bottom, so that after the bottom sheet is placed into the forming cavity 3, the bottom sheet does not cover all the first exhaust holes 4. When the shielding block 11 abuts against the fixed mold 2, the shielding block 11 blocks the first exhaust holes 4 not covered by the bottom sheet, thereby reducing the amount of air flowing from the forming cavity 3 to the negative pressure groove 8, and facilitating the air pump to draw negative pressure in the negative pressure groove 8.

[0044] Referring to Figure 2 , Figure 4 , both support frames 5 are fixedly provided with a first cooling pipe 12, and the pipe body of the first cooling pipe 12 is fixedly provided with a second cooling pipe 13. The end of the second cooling pipe 13 away from the first cooling pipe 12 is arranged towards the forming cavity 3.

[0045] Let the first cooling pipe 12 connect the water pump, and let the water pump supply water to the first cooling pipe 12. After the steam heats the ETPU foaming particles, the water pump sends water into the first cooling pipe 12, and the water inside the first cooling pipe 12 is sprayed from the second cooling pipe 13 towards the movable mold 1 and the fixed mold 2, thereby accelerating the cooling of the ETPU foaming particles to form the middle bottom.

[0046] Referring to Figure 2 , the fixed mold 2 is fixedly provided with a sealing strip 14 on the side away from the movable mold 1. When the driving part 6 drives the negative pressure block 7 to move towards the fixed mold 2, the negative pressure block 7 presses the sealing strip 14, and each negative pressure groove 8 is in the area surrounded by the sealing strip 14, thereby improving the sealing between the negative pressure block 7 and the fixed mold 2, and facilitating the drawing of negative pressure in the negative pressure groove 8.

[0047] Referring to Figure 5 , the movable mold 1 is fixedly provided with a movable shielding cover 15, and the fixed mold 2 is fixedly provided with a fixed shielding cover 16. The opening of the movable shielding cover 15 and the opening of the fixed shielding cover 16 are arranged towards each other. When the movable mold 1 and the fixed mold 2 are closed and abut against each other, the opening edge of the movable shielding cover 15 and the opening edge of the fixed shielding cover 16 abut against each other, thereby wrapping the movable mold 1 and the fixed mold 2. When steam is introduced into the forming cavity 3 for heating and the steam is discharged from the first exhaust hole 4, the steam is gathered between the movable shielding cover 15 and the fixed shielding cover 16, thereby reducing the possibility of the steam sprayed from the first exhaust hole 4 injuring the staff.

[0048] Meanwhile, the steam inside the movable shielding cover 15 and the fixed shielding cover 16 is also cooled in the process of waiting for the ETPU foaming particles inside the forming cavity 3 to cool and form the midsole. When the movable mold 1 and the fixed mold 2 are opened and move away from each other, the steam is condensed into water and then discharged. A water collecting groove can be arranged below the movable shielding cover 15 and the fixed shielding cover 16 to collect the water, thereby facilitating the recycling of the water. In another embodiment, a water drainage pipeline can be connected to the movable shielding cover 15 and the fixed shielding cover 16, thereby discharging the water. After the steam is condensed into water, the amount of steam discharged after the movable shielding cover 15 and the fixed shielding cover 16 move away from each other is small, thereby reducing the environmental temperature rise caused by the steam and improving the comfort of the workers.

[0049] The pipeline for injecting the ETPU foaming particles into the forming cavity 3 is connected to the feeding port after penetrating through the movable shielding cover 15 and the support frame 5. The pipeline for injecting the steam into the forming cavity 3 is connected to the air inlet after penetrating through the movable shielding cover 15 and the support frame 5. The air pump is connected to the first cooling pipe 12 after penetrating through the fixed shielding cover 16 and the support frame 5. The driving member 6 is a cylinder, the cylinder body of which is outside the fixed shielding cover 16, and the piston rod of the cylinder is connected to the negative pressure block 7 after penetrating through the support frame 5.

[0050] The implementation principle of the mold for integrally forming the shoe sole in the embodiment of the application is that the bottom sheet is placed inside the forming cavity 3, and then the movable mold 1 and the fixed mold 2 are moved close to each other to form a mold, so that the movable shielding cover 15 and the fixed shielding cover 16 are tightly wrapped around the movable mold 1 and the fixed mold 2.

[0051] The driving member 6 and the negative pressure pump are started, the driving member 6 drives the negative pressure block 7 to tightly abut against the fixed mold 2, and the negative pressure pump extracts the air inside the negative pressure groove 8, so that a pressure difference is formed between the negative pressure groove 8 and the forming cavity 3, and then the bottom sheet is tightly abutted against the inner wall of the forming cavity 3 close to the side of the negative pressure block 7.

[0052] Then, the ETPU foaming particles are injected into the forming cavity 3. During the injection of the ETPU foaming particles, the bottom sheet has been tightly pressed against the inner wall of the forming cavity 3 close to the side of the negative pressure block 7, so that the movement of the bottom sheet caused by the ETPU foaming particles is reduced, thereby improving the yield of the shoe sole.

[0053] After the injection of the ETPU foaming particles is completed, the negative pressure pump is turned off, and the driving member 6 drives the negative pressure block 7 to move away from the fixed mold 2, so that the first air vent 4 is opened. Then, the steam is injected into the forming cavity 3 to heat the ETPU foaming particles, and the steam is discharged into the inside of the movable shielding cover 15 and the fixed shielding cover 16 after passing through the holes reserved in the bottom sheet and the first air vent 4, thereby reducing the possibility of the steam injuring the workers.

[0054] After the ETPU foaming particles are heated, water is sprayed to the movable mold 1 and the fixed mold 2 through the first cooling pipe 12 and the second cooling pipe 13, so as to accelerate the cooling of the ETPU foaming particles to form the midsole, and the midsole and the outsole form the sole. Then the movable mold 1 and the fixed mold 2 are separated to take out the sole.

[0055] Embodiment 2.

[0056] The embodiment of the present application discloses a mold for integrally forming a sole.

[0057] With reference to Figure 6 , Figure 7 The mold for integrally forming a sole of the embodiment of the present application is different from that of the embodiment 1 in that the negative pressure groove 8 is internally provided with a shielding piece 17, the inner bottom wall of the negative pressure groove 8 is provided with a plurality of mounting grooves 18, the mounting grooves 18 are internally provided with support blocks 19, the support blocks 19 are fixedly installed with support rods 20 on the side close to the fixed mold 2, the support rods 20 are fixedly installed with pressing plates 21 on the end away from the support blocks 19, and the pressing plates 21 are connected with the shielding piece 17. The pressing plates 21 are fixedly installed with fixed needles 22 on the side away from the support rods 20, and the fixed needles 22 are used for inserting into the shielding piece 17.

[0058] The implementation principle of the mold for integrally forming a sole of the embodiment of the present application is as follows: according to the area of the outsole not covering the forming cavity 3, the shielding piece 17 is formed by cutting the area of the outsole not covering the forming cavity 3 into the shape of the waste material with a higher melting temperature than the ETPU foaming particles. The shielding piece 17 is placed in the negative pressure groove 8, then the support blocks 19 are inserted into the mounting grooves 18, and the fixed needles 22 are inserted into the shielding piece 17. When the negative pressure block 7 tightly abuts against the fixed mold 2, the shielding piece 17 also tightly abuts against the fixed mold 2, so as to shield the first exhaust holes 4 in the uncovered area of the outsole. The first exhaust holes 4 in the uncovered area of the outsole are shielded, so as to facilitate the negative pressure groove 8 to be negatively pressurized by the air pump.

[0059] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
