Description

Technical Field

[0001] The present invention relates to the field of shoe cover molds, and particularly to a shoe cover dipping mold. Background Art

[0002] A shoe cover dipping mold is a forming mold for latex shoe covers. The production process of latex shoe covers is to immerse the shoe cover dipping mold into the prepared latex slurry, and then take out the shoe cover dipping mold. The latex slurry adhered to the shoe cover dipping mold is made into latex shoe covers through steps such as drying and demolding.

[0003] During the process of producing latex shoe covers by using a shoe cover dipping mold, a large amount of burrs will be generated at the shoe cover collar of the latex shoe cover, resulting in the need for subsequent trimming of the collar of the latex shoe cover. And the burrs are very thin and soft, making it difficult to remove, which requires a lot of manpower and time, increasing the production cost of the latex shoe cover. At the same time, trimming the burrs subsequently will cause the appearance of the product to be uneven and the product to be unsightly. Summary of the Invention

[0004] Based on this, it is necessary to provide a shoe cover dipping mold that avoids trimming the latex shoe cover.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A shoe cover dipping mold, comprising:

[0007] A shoe mold main body having a necking portion, the shoe mold main body being used for dipping and forming a latex shoe cover, and enabling the dipped and formed latex shoe cover to form a shoe cover collar at the necking portion;

[0008] A slurry scraping ring attached to the necking portion along the circumferential direction of the necking portion, and the slurry scraping ring can also move vertically relative to the shoe mold main body to scrape off the excess slurry at the necking portion.

[0012] In one embodiment, the shoe cover dipping mold further comprises a scraping jacket, the scraping ring is attached to the inner wall of the scraping jacket, and the scraping jacket can be manipulated to drive the scraping ring to move vertically relative to the shoe mold body to scrape off the slurry.

[0013] In one embodiment, the shoe cover dipping mold also includes a limiting structure, which includes a sliding block and a sliding groove. One of the sliding block and the sliding groove is arranged on the shoe mold body, and the other is arranged on the scraper jacket. Part of the structure of the sliding block is embedded in the sliding groove, and the sliding block can move vertically in the sliding groove to abut against the two end groove walls of the sliding groove along the vertical direction.

[0014] In one of the embodiments, a damping ring is provided on a side of the sliding block facing the sliding groove, and a side of the damping ring facing away from the slurry scraper jacket abuts against an inner wall of the sliding groove.

[0015] In one of the embodiments, the shoe mold body is further provided with an identification groove extending in the circumferential direction on the lower side of the sliding groove. When the operator wears the mesh lining on the outer wall of the shoe mold body, the identification groove is used to instruct the operator to wear the mesh lining to the identification groove; when the sliding block moves to the lower groove wall of the sliding groove along the scraping direction, the scraping ring scrapes the slurry into the identification groove and forms an inner convex rib of the edge of the shoe cover cuff.

[0016] In one of the embodiments, the outer wall of the shoe mold body includes a gradient area, the radial dimension of the gradient area gradually increases from the upper side of the shoe mold body to the lower side of the shoe mold body, and the scraping ring is an elastic ring, which gradually hugs the shoe mold body and accumulates elastic scraping force during the process of moving from the upper side to the lower side along the gradient area.

[0017] In one of the embodiments, the shoe mold body is provided with a groove surrounding the outer wall of the shoe mold body on the lower side of the scraper ring; and / or, the shoe mold body is also sprayed with an inhibitor in a continuous area on the upper part of the scraper ring, and the inhibitor is used to inhibit the latex slurry from dipping and molding; and / or, the scraper ring is an elastic ring.

[0018] It can be seen from the above technical solutions that the embodiments of the present invention have at least the following advantages and positive effects:

[0019] In the shoe cover dipping mold in the embodiment of the present invention, since the slurry scraping ring can move vertically relative to the shoe mold main body, scraping the excess slurry above the closing part with the slurry scraping ring before the latex slurry is dried can prevent the formation of burrs at the closing part after the excess slurry is dried and formed. After the latex shoe cover is formed on the shoe mold main body, subsequent trimming treatment is not required or the workload of subsequent trimming treatment can be reduced, effectively reducing the labor and time costs of producing latex shoe covers, and at the same time improving the aesthetics of latex shoe covers.

[0034] First embodiment

[0035] Reference Figure 1 , the present invention provides a shoe cover dipping mold 10, which is a forming mold for making latex shoe covers by the dipping method. Specifically, when using the shoe cover dipping mold 10 to produce latex shoe covers, first immerse the shoe cover dipping mold 10 into the prepared latex slurry, and then take out the shoe cover dipping mold 10. The latex slurry will adhere to the outer surface of the shoe cover dipping mold 10 to form, and after steps such as drying and demolding, the product latex shoe cover is obtained.

[0036] Reference Figure 2 , the shoe cover dipping mold 10 includes a shoe mold main body 100 and a slurry scraping structure 200. The shoe mold main body 100 has a necking part 110. The shoe mold main body 100 is used for dipping and forming latex shoe covers, and enables the dipped and formed latex shoe covers to form a shoe cover hem at the necking part 110. The slurry scraping structure 200 is attached to the necking part 110 along the circumferential direction of the necking part 110, and the slurry scraping structure 200 can move relative to the shoe mold main body 100 in the vertical direction to scrape off the excess slurry adhering to the upper side of the necking part 110 during the forming process of the latex shoe covers.

[0037] In the shoe cover dipping mold 10 in the embodiments of the present invention, since a slurry scraping structure 200 for scraping off excess slurry is provided on the outer wall of the shoe mold body 100, during the production of the latex shoe cover, after the shoe cover dipping mold 10 is taken out of the latex slurry, the slurry scraping structure 200 can be operated to move vertically to scrape off the excess latex slurry, and then subsequent steps such as drying and demolding are carried out, thereby preventing the formation of burrs at the mouth of the latex shoe cover, eliminating the need for subsequent trimming, effectively reducing the labor and time costs of producing the latex shoe cover, and at the same time avoiding unevenness at the mouth of the latex shoe cover during manual trimming of burrs, improving the aesthetics of the latex shoe cover.

[0038] The slurry scraping structure 200 includes a slurry scraping outer sleeve 210 and a slurry scraping ring 220. The slurry scraping outer sleeve 210 is sleeved on the outer wall of the shoe mold body 100 and can move vertically relative to the shoe mold body 100. A part of the structure of the slurry scraping ring 220 is embedded in the inner wall of the slurry scraping outer sleeve 210. The side of the slurry scraping ring 220 facing away from the slurry scraping outer sleeve 210 is attached to the outer wall of the shoe mold body 100. The slurry scraping outer sleeve 210 can be manipulated to drive the slurry scraping ring 220 to move vertically relative to the shoe mold body 100 to scrape off the slurry, and the slurry scraping outer sleeve 210 can facilitate the operation.

[0039] Specifically, in one embodiment, the slurry scraping ring 220 is an elastic ring. The slurry scraping ring 220 presses against the inner wall of the slurry scraping outer sleeve 210 and the outer wall of the shoe mold body 100 through elastic deformation to ensure that the slurry scraping ring 200 can scrape off the excess latex slurry on the outer wall of the shoe mold body 100 completely. At the same time, since the shape of the shoe mold body 100 is made by imitating the shape of the formed latex shoe cover, when the shoe cover dipping mold 10 is a forming mold for low-top latex shoe covers, the closing part 110 extends to the lower side of the shoe mold body 100 to form a region with an increasing radial dimension. The elastic slurry scraping ring 220 can move to the region with an increasing radial dimension of the closing part 110 and expand by relying on its elasticity, without the need to replace the slurry scraping ring 220 with a larger radial dimension. It should be noted that the cross-section of the slurry scraping ring 220 can be circular, rectangular, T-shaped, etc., and the present invention does not make any limitation on the outer shape structure of the slurry scraping ring 220.

[0040] It should be noted that, in other embodiments, the slurry scraping ring 220 can be set as a non-elastic rigid ring. The scraping effect of the rigid ring on the excess latex slurry is not as good as that of the elastic ring, and there may be a situation where the latex slurry is not scraped off completely. There may still be a small amount of burrs after the latex shoe cover is formed, and the mouth of the shoe cover needs to be trimmed manually. However, setting the slurry scraping ring 220 as a rigid ring still reduces the workload of manual trimming compared to the case without the slurry scraping ring 220, reducing the labor and time costs. For the slurry scraping ring 220 being a rigid ring, the radial dimension of the slurry scraping ring 220 in the vertical sliding region of the closing part 110 should be set to be unchanged in radial dimension.

[0041] In one embodiment, the latex scraping ring 220 includes a glue-resistant layer formed at least on the outer surface of the latex scraping ring 220. Inevitably, latex slurry will adhere to the latex scraping ring 220 during operation. The glue-resistant layer can prevent the adhered latex slurry from solidifying and forming on the outer surface of the latex scraping ring 220, avoiding adhesion and affecting the latex scraping effect. It should be noted that in other embodiments, the outer surface of the latex scraping ring 220 may not have a glue-resistant layer. Instead, before the shoe cover dipping mold 10 is immersed in the latex slurry, a glue-resistant coating is applied to the outer surface of the latex scraping ring 220, or a tape with a glue-resistant layer is attached to the outer surface of the latex scraping ring 220, so as to prevent the latex slurry adhered to the latex scraping ring 220 from forming. As long as the technical solution that the outer surface of the latex scraping ring 220 has a glue scraping layer before the shoe cover dipping mold 10 is immersed in the latex slurry can be achieved, it should be within the protection scope of the present invention.

[0042] It should be noted that the glue-resistant layer applied to the above-mentioned latex scraping ring 220 is at least one or any combination of at least two of a Teflon layer, an enamel layer, a polytetrafluoroethylene layer, an emulsified silicone oil layer, a dimethyl silicone oil layer, and a sulfide layer.

[0043] In one embodiment, the latex scraping outer sleeve 210 is detachably connected to the shoe mold main body 100. The latex scraping outer sleeve 210 is composed of two detachable arc-shaped outer sleeves 211. When the latex scraping outer sleeve 210 is installed on the shoe mold main body 100, the latex scraping ring 220 can be first sleeved on the outer wall of the shoe mold main body 100, and then the two arc-shaped outer sleeves 211 are aligned with the latex scraping ring 220, and then the two arc-shaped outer sleeves 211 are connected. The connection method between the two arc-shaped outer sleeves 211 can be bolt connection, clamping connection, sleeve connection, etc. During the production process of the latex shoe cover, the latex scraping ring 220 is worn due to frequent friction with the outer wall of the shoe mold main body 100. When the latex scraping ring 220 is worn to the extent that it needs to be scrapped, a new latex scraping ring 220 can be replaced by disassembling and assembling the latex scraping outer sleeve 210, so as to achieve rapid maintenance of the shoe cover dipping mold 10 and reduce the maintenance cost.

[0044] Combined with reference to Figure 3 and Figure 4, in one embodiment, a sliding block 230 is provided on the inner wall of the slurry scraping jacket 210, and a sliding groove 120 cooperating with the sliding block 230 is provided on the outer wall of the mold body 100. A part of the structure of the sliding block 230 is embedded in the sliding groove 120, so that the sliding block 230 can move up and down in the sliding groove 120 vertically. When the sliding block 230 slides to the upper or lower side wall of the sliding groove 120 vertically, the sliding block 230 is blocked and cannot continue to slide forward. That is, the sliding block 230 and the sliding groove 120 together form a limiting structure to control the vertical movement of the slurry scraping jacket 210 relative to the shoe mold body 100. During the production process, when operating the slurry scraping jacket 210, due to excessive force, after scraping off the excess latex slurry, part of the latex slurry used for the formation of the latex shoe cover is continuously scraped off, resulting in an incomplete latex shoe cover after formation and affecting the product quality. Limiting the slurry scraping jacket 210 through the lower side wall of the sliding groove 120 can effectively solve this problem. At the same time, the upper side wall of the sliding groove 120 can prevent the slurry scraping jacket 210 from detaching from the top of the shoe mold body 100 due to excessive force, avoiding the operation steps of re-sheathing the slurry scraping jacket 210 after it detaches from the shoe mold body 100 and reducing the production cost. At the same time, the position of the lower side wall of the sliding groove 120 on the shoe mold body 100 is adapted to the position of the closing part 110, that is, when the sliding block 230 moves to the lower side wall of the sliding groove 120, the lower edge of the slurry scraping ring 220 on the slurry scraping jacket 210 is exactly adjacent to the upper edge of the closing part 110 corresponding to the mouth of the latex shoe cover, so that the remaining latex slurry after the slurry scraping ring 220 scrapes off the excess slurry is exactly the slurry required for the formation of the latex shoe cover.

[0045] It should be noted that, in other embodiments, the sliding groove 120 can be provided on the inner wall of the slurry scraping jacket 210, and the sliding block 230 matching the sliding groove 120 is provided on the outer wall of the shoe mold body 100. The present invention does not limit the specific position of the limiting structure.

[0046] Specifically, the sliding block 230 can be a continuous annular structure extending along the circumferential direction of the shoe mold body 100 and closed in the circumferential direction, or can be a plurality of block structures in a disconnected state along the circumferential direction of the shoe mold body 100. The sliding groove 120 is matched with the shape and sliding track of the sliding block 230, so that the sliding block 230 can move vertically relative to the shoe mold body 100 in the sliding groove 120.

[0047] Reference Figure 4In one embodiment, a damping ring 240 is provided on one side of the sliding block 230 facing the sliding groove 120. The damping ring 240 is embedded in the sliding block 230 along one side of the radial direction of the shoe mold body 100 and the other end presses against the sliding groove 120. The damping ring 240 can play a buffering role and can effectively avoid the wear caused by the direct contact between the sliding block 230 and the sliding groove 120. After long-term wear, the contact surface between the sliding block 230 and the sliding groove 120 is uneven, resulting in the unsmooth vertical movement of the slurry scraping jacket 210. In addition, the damping ring 240 can also play a role in controlling the slurry scraping speed. When the slurry scraping structure 200 scrapes the latex slurry vertically, the sliding friction between the damping ring 240 and the sliding groove 120 will continue to act on the sliding block 230, so that the sliding block 230 will not suddenly slide from the upper side groove wall of the sliding groove 120 to the lower side groove wall, thereby controlling the slurry scraping speed of the rubber scraping ring 220 not to be too fast, and the slurry scraping is more sufficient and uniform. When the damping ring 240 is worn to a certain extent, a new damping ring 240 can be replaced by disassembling the scraper jacket 210 to achieve rapid maintenance of the shoe cover dipping mold 10 and save maintenance costs. Specifically, the damping ring 240 is an elastic ring, which can maintain the state of pressing the sliding groove 120 at all times through its own deformation. It should be noted that in other embodiments, the damping ring 240 can be set as a rigid ring, and the present invention does not impose any limitation on whether the damping ring 240 is set as an elastic ring. At the same time, the cross-section of the damping ring 240 can be circular, rectangular, T-shaped, etc., and the present invention does not impose any limitation on the external structure of the damping ring 240.

[0048] It should be noted that, in other embodiments, the shoe cover dipping mold 10 may not be provided with the damping ring 240. In this case, the shoe cover dipping mold 10 will have a reduced service life due to frequent wear between the sliding block 230 and the sliding groove 120, and a shorter scrapping cycle, which increases the material cost in the production process.

[0049] refer to Figure 4 The outer wall of the shoe mold body 100 includes a gradient region 105, the radial dimension of the gradient region 105 gradually increases from the upper side of the shoe mold body 100 to the lower side of the shoe mold body 100, and the rubber scraper ring 220 is an elastic ring, which gradually hugs the shoe mold body 100 and accumulates elastic scraping force during the movement from the upper side to the lower side along the gradient region 105. During the scraping process of the scraper ring 220, since the radial dimension of the gradient region 105 gradually increases, the scraper ring 220 hugs the shoe mold body 100 through elastic deformation to avoid a gap between the inner wall of the scraper ring 220 and the outer wall of the shoe mold body 100, and the excess slurry can be effectively scraped off.

[0050] Continue to refer Figure 2, the outer shape of the shoe mold body 100 is formed by copying the outer shape structure of the produced latex shoe cover, that is, the outer shape of the shoe mold body 100 is determined by a certain shoe type matching the produced latex shoe cover, or by an optimized structure formed by integrating the structures of multiple approximate shoe types matching the produced latex shoe cover. It should be noted that the shoe mold body 100 can be made of ceramics, cast aluminum, glass, stainless steel or other materials.

[0051] In one embodiment, an inhibitor capable of inhibiting latex film formation is sprayed or smeared on the continuous area above the closing part 110. The inhibitor can be a mold release agent, a slip agent, etc. As long as it can inhibit the formation of a film by the latex slurry in the continuous area above the closing part 110 of the shoe mold body 100, it should be within the protection scope of the present invention. It should be noted that in other embodiments, the continuous area above the closing part 110 may not be covered with an inhibitor. In this case, the latex slurry may form a film at this position, thereby affecting the slurry scraping effect.

[0052] In one embodiment, a marking groove 130 is provided on the outer wall of the shoe mold body 100. The marking groove 130 extends along the circumferential direction of the shoe mold body 100 and is circumferentially closed. When the above-mentioned sliding block 230 moves along the slurry scraping direction to the lower side wall of the sliding groove 120, the slurry scraping ring 220 scrapes the slurry into the marking groove 130. The slurry in the marking groove 130 forms an inner rib on the edge of the shoe cover mouth after drying, and the formed inner rib can enhance the tensile strength of the edge of the shoe cover mouth. In addition, the marking groove 130 can also be used as a demarcation line for distinguishing the excess slurry on the shoe mold body 100. The slurry in the area above the upper edge of the marking groove 130 is excess slurry, and the slurry in the area below the marking groove 130 is the slurry required for the formation of the latex shoe cover. The marking groove 130 can play a role in marking. During the production process of the latex shoe cover, the operator needs to wear a grid lining on the outer wall of the shoe mold body 100, and the marking groove 130 is used to indicate the operator to wear the grid lining to the position where the marking groove 130 is located. Specifically, the cross-section of the marking groove 130 is V-shaped. At this time, the bottom of the marking groove 130 is a straight line, and the marking effect is more obvious. It can be understood that the cross-section of the marking groove 130 can also be rectangular, arc-shaped, etc. The present invention does not limit the shape of the marking groove 130.

[0053] It should be understood that in other embodiments, the marking groove 130 is composed of multiple disconnected groove-like structures extending along the circumferential direction. In this case, the tensile strength increased by the inner rib formed on the edge of the shoe cover mouth is smaller, and at the same time, the marking effect is not obvious.

[0054] In one embodiment, a groove 140 that extends circumferentially along the shoe mold body 100 and is circumferentially closed is provided in the lower region of the necking portion 110. The groove 140 can ensure that during the process of impregnating the shoe mold body 100 with latex, the latex can enter the groove along the opening of the groove 140 to form a thicker collar edge. During the long-term use of the latex shoe cover, the collar position is damaged due to stretching deformation during frequent putting on and taking off. The provision of the groove 140 can make the collar edge of the latex shoe cover thicker, enhancing the tensile strength of the collar edge, and thus avoiding damage to the latex shoe cover caused by stretching during long-term use. It should be noted that when not considering enhancing the tensile strength at the collar of the latex shoe cover, the shoe mold 100 may not be provided with the groove 140.

[0055] In one embodiment, the shoe cover impregnation mold 10 further includes a shoe mold fixing structure 150 for fixing the shoe mold body 100 to a production line or a mold base. The specific external structure of the shoe mold fixing structure 150 is adapted to the corresponding fixture or mold base on the production line.

[0056] In one embodiment, the shoe cover impregnation mold 10 is provided with an anti-slip structure. Anti-slip patterns are provided on the shoe bottom and the heel part of the shoe mold body 100. The anti-slip patterns can adopt various transverse, longitudinal or zigzag-shaped ridges to increase the thickness and anti-slip property of the sole of the formed latex shoe cover. At the same time, the anti-slip patterns can adopt a structure of making anti-slip patterns or anti-slip particles on the shoe bottom of the shoe mold body 100. Anti-slip rib patterns can also be provided on the shoe surface part of the shoe mold body 100, and the anti-slip rib patterns can be various transverse, longitudinal or zigzag-shaped shallow groove structures.

[0057] In one embodiment, a product identification is provided on the side or other suitable position of the shoe mold body 100. The product identification can be a concave or convex structure in the shape of a product size, a product brand, a product model, etc.

[0058] Second Embodiment

[0059] Figure 5 Schematically shows an exploded structural view of the second embodiment of the shoe cover impregnation mold 10.

[0060] The shoe cover impregnation mold 10 of this embodiment has basically the same structure as the shoe cover impregnation mold 10 of the first embodiment, except that the shoe cover impregnation mold 10 in this embodiment is not provided with a slurry scraping outer sleeve 210, that is, the scraping rubber ring 220 is the slurry scraping structure 200. During operation and use, the movement of the scraping rubber ring 220 can be controlled by a clamping mechanism on a mechanical device on the production line or a mold base. The scraping rubber ring 220 can move vertically from the upper side to the lower side of the shoe mold body 100 for slurry scraping. In addition, the scraping rubber ring 220 can also be controlled to move vertically from the upper side to the lower side of the shoe mold body 100 for slurry scraping by manual operation. Although the production efficiency of manual operation is low, the slurry scraping effect can also be achieved.

[0061] In this embodiment, the shoe mold main body 100 may further be provided with a retaining edge 160. The retaining edge 160 extends along the circumferential direction of the shoe mold main body 100. The retaining edge 160 is located at the upper edge of the closing part 110 and protrudes from the outer wall of the shoe mold main body 100. When the slurry scraping ring 220 moves along the slurry scraping direction to the retaining edge 160, the retaining edge 160 can limit the slurry scraping ring 220 from continuing to move downward along the vertical direction, avoiding the slurry scraping ring 220 from scraping off the latex slurry required for the formation of the latex shoe cover. It should be noted that the retaining edge 160 may be a closed continuous annular structure or a multi-block structure that is disconnected along the circumferential direction.

[0062] Third Embodiment

[0063] Figure 6 Schematically shows the structural diagram of the third embodiment of the shoe cover dipping mold 10.

[0064] The shoe cover dipping mold 10 of this embodiment is basically the same in structure as the shoe cover dipping mold 10 of the first embodiment. The difference lies in that the slurry scraping outer sleeve 210 in this embodiment includes an upper sleeve body 212 and a lower sleeve body 213 along the axial direction. Among them, the thickness of the upper sleeve body 212 is less than the thickness of the lower sleeve body 213, while in the first embodiment Figure 1 the thickness of the shown slurry scraping outer sleeve 210 is equivalent to that all extended by the lower sleeve body 213 along the axial direction. The slurry scraping outer sleeve 210 in this embodiment saves materials compared with the slurry scraping outer sleeve 210 of the first embodiment and has a lower cost.

[0065] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
