Description

Technical Field

[0001] This utility model relates to the field of footwear, and more particularly to a shoe-making mold and a shoe sole manufactured using the shoe-making mold. Background Technology

[0002] Currently, the production of supercritical foamed insoles mainly relies on two types of mold structures: Type A dynamic pressure mold and Type B constant pressure mold. Type A mold fixes the middle frame to the fixed mold side and forms the parting surface through mold displacement, relying on mold displacement to complete the compression molding of the foam. Type B mold integrates the middle frame to the mold displacement side, establishes the parting surface through mold displacement, and uses the fixed mold to apply pressure to achieve shaping.

[0003] However, the aforementioned mold architectures are all single-cavity structures, meaning that a single mold can only support molding of a single material. Multi-material components need to be manufactured through multiple molds and manually bonded to the sole, resulting in fragmented processes, extending the production cycle by 30%-50%, and causing intermittent VOC emissions due to multi-processing, leading to significant cumulative environmental pollution problems. In addition, a single midsole typically requires two sets of molds to work together, increasing the proportion of mold investment and maintenance costs by 15%-25%, and adding 10%-15% to the marginal cost of manual bonding.

[0004] Therefore, the production process of multi-material supercritical foam integral molding structure using existing mold technology is forced to be broken down into discrete processes, which increases system complexity and overall cost. In addition, it also limits the application of functional gradient material combinations such as shock-absorbing support structures. Utility Model Content

This allows two different raw materials to enter the first and second chambers separately and remain separated, thereby achieving integrated molding of the two materials. This avoids the secondary bonding process, reduces production processes and cycles, lowers costs, and reduces VOC emissions. Furthermore, the plate body can be removed from the mold and placed into a support assembly, which can then be integrated with the sole of both materials. Attached Figure Description

[0033] To better understand the purpose, structure, and function of this utility model, the shoe-making mold of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] This invention relates to a shoe-making mold for producing the sole of a pair of shoes. The mold includes a left foot unit and a right foot unit, which are symmetrically arranged and manufactured simultaneously on the mold to save mold space and improve economic efficiency. Those skilled in the art can adjust the number of left and right foot units according to actual needs, as long as each left and / or right foot unit is independent and does not affect or interfere with the production process. Therefore, the following description focuses only on the overall structure and the specific structure of the right foot unit in this embodiment; the left foot unit will be configured accordingly and will not be elaborated upon further.

[0035] like Figures 1 to 15 As shown, the shoe mold has a square overall shape and includes a first mold assembly 100, a middle plate assembly 200, and a second mold assembly 300 arranged sequentially from top to bottom. The middle plate assembly 200 includes a plate body 201 and a feed hole 207 disposed on the plate body 201. The first mold assembly 100 and the plate body 201 enclose a first chamber for accommodating one type of shoe sole raw material. The second mold assembly 300 and the plate body 201 enclose a second chamber for accommodating another type of shoe sole raw material. The first mold assembly 100 is provided with a first feed port 101 and a second feed port 102. The first feed port 101 communicates with the first chamber. The first chamber is provided with... The hollow tubular feeding section 117 has one end connected to the feeding hole 207 and the other end connected to the second feeding port 102. During injection, the mold is first opened and the seam is opened. One type of shoe sole raw material is injected into the first chamber through the first feeding port 101, and another type of shoe sole raw material is injected into the second chamber through the second feeding port 102. The mold is closed to extrude the raw materials in the two chambers. After the mold is opened, the plate 201 is removed. Then the mold is closed again for secondary foaming, so that the raw materials are fully foamed and fused together. This achieves the effect of molding two types of shoe sole raw materials in one go through a set of molds, which simplifies the production process and reduces production costs.

[0036] It should be noted that seam opening involves separating the mold structure that forms the cavity to create a gap, fully filling the corresponding cavity with different raw materials, and then pressing the raw materials through the closed mold to form the desired appearance of the shoe sole.

[0037] Specifically, the first mold assembly 100 includes a fixed mold and a first frame portion 103. One side of the first frame portion 103 is connected to the fixed mold, and the other side is connected to the plate body 201 of the middle plate assembly 200. The fixed mold includes a feed plate 104 and a first inner core 105. One side of the first inner core 105 is connected to the feed plate 104, and the other side is correspondingly arranged with the plate body 201. Thus, the plate body 201, the first inner core 105, and the first frame portion 103 enclose a first chamber. The first inner core 105 is provided with a first hole 119 and a second hole 120, which are respectively corresponding to the first feed port 101 and the second feed port 102 on the feed plate 104, for raw materials to enter the chamber through the first inner core 105. The feed plate 104 and the first inner core 105 are fixedly connected by a bolt structure so that the fixed mold can move as a whole structure when the mold is opened and the gap is opened.

[0038] like Figure 1 , Figure 13 and Figure 14 As shown, the feed plate 104 has first screw holes at its four corners. The middle plate assembly 200 also includes a frame 202, which is located outside the plate body 201. Second screw holes corresponding to the first screw holes are located at the four corners of the frame 202, and the first and second screw holes are connected by support columns 106, thus forming a fixed connection between the frame 202 and the feed plate 104. A water pipe interface 107 is provided in the middle of the feed plate 104. This interface 107 is used to install a water pipe for inputting cooling water. A fixing pin 108 is provided on one side of the interface to prevent the water pipe from rotating. A hollow section 109 is provided in the middle of the plate body 201, and a nozzle connected to the water pipe is provided on the hollow section 109 to spray water onto the finished product area.

[0039] The second mold includes a transfer mold 301 and a second frame portion 302. One side of the second frame portion 302 is connected to the transfer mold 301, and the other side is connected to the plate body 201 of the middle plate assembly 200. The transfer mold 301 includes a base plate 303 and a second inner core 304. One side of the second inner core 304 is connected to the base plate 303, and the other side is correspondingly arranged with the plate body 201. Thus, the base plate 303, the second inner core 304, and the second frame portion 302 enclose a second chamber. When the first mold assembly 100 and the second mold assembly 300 are closed, the plate body 201 forms a barrier between the two. Supercritical raw materials of different materials or colors, such as ETPA, PEBAX, ETPU, TPEE, etc., are injected into the two chambers through a material gun.

[0040] like Figure 14 and Figure 15As shown, machine tool holes 203 are provided on the four outer edges near the plate frame 202. The fixed mold is hung on the machine tool through the machine tool holes 203, and the plate body 201 is hung on the moving mold 301 through the limiting holes 204 provided on its outer edge. Multiple mold pins 305 and moving mold machine tool holes 306 are provided on the four outer edges of the base plate 303 for fixing the moving mold 301 and the machine tool. The plate body 201 is hung on the base plate 303 through the limiting posts 307 on the base plate 303.

[0041] In this embodiment, the second inlet 102 is located on the side near the forefoot of the sole, and the first inlet 101 is located on the side near the heel of the sole. It is understood that those skilled in the art can make improvements according to actual needs, and set the inlet 117 on the side near the heel of the sole, thereby swapping the positions of the two inlets.

[0042] Furthermore, such as Figure 3 and Figure 8 As shown, the first inner core 105 includes a hollow tubular first vent 110 and a second vent 111. The first vent 110 and the second vent 111 extend from the first hole 119 and the second hole 120 toward the direction of the feed plate 104, respectively. The first vent 110 is correspondingly arranged with the first feed port 101, and the second vent 111 is correspondingly arranged with the second feed port 102. The first vent 110 is sleeved on the feed part 117 and forms a tight connection with the feed part 117 when the mold is closed. Combined with the blocking effect of the plate 201, the raw material entering the second feed port 102 enters only the second chamber after passing through the feed part 117, realizing the complete isolation of the two raw materials in the mold.

[0043] The first vent 110 has a plurality of first walls on the side near the first feed port 101, with gaps between adjacent first walls. The second vent 111 has a plurality of second walls 112 on the side near the second feed port 102, with gaps between adjacent second walls 112. This structure with gaps helps to discharge high-temperature steam from the mold, making the density of the molded shoe sole in the feed port area uniform and avoiding the problem of local hardening.

[0044] Preferred, such as Figure 6 and Figure 13As shown, it also includes a plurality of first guide structures disposed on the first frame portion 103. The first guide structures are located between the plate body 201 and the first frame portion 103. The first guide structure includes a first guide post 113, and a first spring and a first limiting part disposed at both ends of the first guide post 113. During feeding, the plate body 201 and the first frame portion 103 remain in close contact. The first spring recovers its deformation on the first guide post 113, thereby lifting the first frame portion 103 and pulling it apart from the first inner core 105. The first guide post 113 plays the role of positioning and fixing the first frame portion 103. The first limiting part on the first guide post 113 is set as a limiting nut structure to limit the stroke of the first spring, prevent the first frame portion 103 from separating from the mold structure, and improve the stability of the mold when pulling the gap. The first guide structure also includes a first tube position 116 disposed on the feed plate 104 and a first limiting ear 114 disposed on the first frame portion 103. A first spring is disposed below the first limiting ear 114. The first guide post 113 passes through the first limiting ear 114 and cooperates with the first limiting portion to control the stroke of the first frame portion 103.

[0045] like Figure 9 and Figure 15 As shown, the system also includes multiple second guide structures disposed on the second frame portion 302. These second guide structures are located between the plate body 201 and the second frame portion 302. Each second guide structure includes a second guide post 308, and second springs and second limiting portions disposed at both ends of the second guide post 308. After the second frame portion 302 is lifted by the second spring, it is pulled apart from the mold transfer 301, keeping the plate body 201 and the second frame portion 302 in close contact. The second guide post 308 also includes a second limiting ear 309 disposed on the second frame portion 302. The second spring is disposed below the second limiting ear 309. After passing through the second limiting ear 309, the second guide post 308 engages with the second limiting portion to control the stroke of the second frame portion 302.

[0046] Preferably, the plate 201 and the feeding part 117 are configured as an integrally formed structure to enhance the sealing and connection strength of the connection between the feeding part 117 and the plate 201, thereby improving the stability of the mold and the product quality. Figure 4 As shown, handles 118 are provided on both sides of the plate 201 to facilitate the installation and removal of the plate 201.

[0047] It is understood that those skilled in the art can select at least one specific structure of the first mold assembly 100 and the second mold assembly 300 according to the actual situation, and at least one of the first guide structure and the second guide structure can also basically achieve the functions and beneficial effects described above.

[0048] Preferred, such as Figures 13 to 15As shown, it also includes a first shovel base 115 disposed on the first frame portion 103, a second shovel base 205 disposed on the plate body 201, a third shovel base 206 disposed on the plate frame 202, a fourth shovel base 310 disposed on the second frame portion, and a fifth shovel base 311 disposed on the base plate 303. The first shovel base 115 is positioned close to the plate 201 to guide and fix the plate 201 during mold closing. The second shovel base 205 is positioned corresponding to the first shovel base 115 to limit the positioning of the first frame portion 103 and the second frame portion 302, preventing misalignment. The third shovel base 206 is positioned close to the moving mold 301 to guide the plate frame 202 and the moving mold 301 during mold closing. The fourth shovel base 310 is positioned close to the outer edge of the plate 201 and is used to lock the plate during mold opening and seam closing. The fifth shovel base 311 is positioned close to the outer edge of the base plate 303 to guide both the plate 201 and the base plate 303 during mold closing. Through the cooperation of these multiple shovel bases, a complete guiding and limiting system is formed, distributing stress, reducing localized wear, extending the service life of the mold, and improving the repeatability accuracy during automated operation.

[0049] Furthermore, such as Figure 10 and Figure 15 As shown, the mold transfer 301 also includes a plurality of backhoe portions 312 disposed on the base plate 303. The plurality of backhoe portions 312 are arranged around the outside of the second inner core 304, specifically as strip-shaped protrusion structures extending along the outer contour of the second inner core 304. A gap is formed between the backhoe portions 312 and the second inner core 304. The width of the gap is equivalent to the thickness of the second frame portion 302, so that the second frame portion 302 can be locked in the gap. On the one hand, it guides the second frame portion 302 when the mold closes and returns to its original position, and on the other hand, it supports and fixes the second frame portion 302 to prevent the second frame portion 302 from bursting due to excessive pressure during processing. Preferably, the backhoe portions 312 and the base plate 303 are configured as an integrally formed structure to enhance the connection strength between the backhoe portions 312 and the base plate 303 and improve the stability of the mold.

[0050] Preferred, such as Figure 12 As shown, the middle plate assembly 200 also includes a clearance portion 314, which is fitted and disposed below the plate body 201. That is, the clearance portion 314 is located on the side of the plate body 201 facing the second inner core 304, so as to form a clearance space for accommodating the support assembly 208, so that the raw materials in the second space can be further fully foamed.

[0051] Specifically, such as Figure 11 and Figure 12As shown, in order to install a support component 208 made of carbon fiber, nylon sheets, etc., between the two chambers and to integrally mold it with the sole material, a clearance portion 314 is provided below the plate 201 according to the thickness required for installing the support component 208. After the second chamber is filled with raw materials and undergoes the first foaming, the plate 201 and the clearance portion 314 are removed, forming a clearance space in the second chamber by the compression of the clearance portion 314. The support component 208 and the positioning post 313 located below the support component 208 for fixation can then be placed into the clearance space. One end of the positioning post is attached to the mold transfer 301, and the other end is connected to the support component 208. The number of positioning posts can be 5 to 8, depending on the size of the support component 208, as long as they can stably fix the support component 208.

[0052] Furthermore, the plate 201 is provided with several through holes formed by metal printing. The through holes are densely arranged on the entire plate to allow steam to flow smoothly between the first chamber and the second chamber, thereby ensuring that the raw material foams fully and uniformly. The diameter of the through holes is set to 0.1mm to 0.3mm, and the spacing between each through hole is 1mm to 3mm. This parameter setting can ensure the flow of steam and prevent the flow of raw material between the two chambers, thereby achieving efficient production. Preferably, the diameter of the through holes is 0.2mm and the spacing between the through holes is 2mm.

[0053] Preferably, the mold material is aluminum or stainless steel. Aluminum has the characteristics of light weight, good thermal conductivity and easy processing, which can ensure high precision and fast production. Stainless steel has high hardness and can achieve ultra-thin wall thickness, which is conducive to the ventilation and heat conduction of the mold and improves the quality of the product.

[0054] The operating steps of this shoe-making mold are as follows:

[0055] First, hang the mold on the machine. Connect two material guns to different materials respectively. When injecting, open the mold and draw the gap, injecting different materials into the first and second chambers respectively. After injection, extrusion molding is performed. When the bead-like materials are fused together and do not fall off, pull the mold open and remove the plate and the clearance part. Then put the support component in and close the mold again. At this time, the machine introduces steam, so that the beads are fully foamed and fused together, realizing the one-piece molding of two different materials and the support component.

[0056] This utility model also provides a shoe sole, which is made using the shoe-making mold described above and has two different materials and a support component integrally formed.

[0057] The shoe-making mold of this utility model has the following advantages:

[0058] A first mold assembly and a plate body enclose a first chamber, and a second mold assembly and a plate body enclose a second chamber. The first mold assembly has a first feed inlet and a second feed inlet, with the first feed inlet communicating with the first chamber. A feeding section is located within the first chamber, with one end communicating with a feed hole on the plate body and the other end communicating with the second feed inlet. This allows two different raw materials to enter the first and second chambers separately and remain separated, thereby achieving integrated molding of the two materials. This avoids the need for secondary bonding of the two materials, reduces production processes and cycles, lowers costs, and reduces VOC emissions. Furthermore, the plate body can be removed from the mold and placed into a support assembly, which can then be integrated with the sole of the two materials.
