Description

Technical Field

[0001] This utility model relates to a shoe sole production tool, and more particularly to a quick-cooling and quick-heating shoe sole mold. Background Technology

[0002] Shoe sole molds typically involve two stages during the production process: heating and cooling. Traditional shoe sole molds usually have the cavity created on a template. Heating or cooling the shoe sole material inside the cavity is achieved by heating or cooling the template. For example, the cavity and heating or cooling channels are both created on the same template. Heating or cooling media such as steam or cold water flow in the channels to heat or cool the template, which is then conducted to the cavity through the template to heat or cool the shoe sole. The heating or cooling speed is relatively slow, resulting in relatively low production efficiency. The relatively slow heating and cooling speed can easily lead to uneven heating of the shoe sole, causing internal stress and affecting the quality of the shoe sole.

[0003] In view of this, the applicant conducted an in-depth study on the structure of the shoe sole mold, which led to this case. Utility Model Content

[0004] The purpose of this invention is to provide a quick-cooling and quick-heating shoe sole mold with relatively high production efficiency and relatively good sole quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-cooling and quick-heating shoe sole mold includes a support frame, which encloses an inner cavity. A support plate is fixedly or integrally connected to one side of the support frame. A material outlet is provided on the support plate. A cavity seat located in the inner cavity is fixedly or integrally connected to the periphery of the material outlet. A cavity communicating with the material outlet is provided on the cavity seat. A first heat-conducting plate covering the material outlet is detachably and fixedly connected to the support plate. A second heat-conducting plate corresponding to the cavity is fixedly connected to the side of the support frame away from the support plate. Heat-conducting pipes are arranged around the outer wall of the cavity seat.

[0007] As an improvement of this utility model, the second heat-conducting plate is provided with a second hot and cold inlet and a second hot and cold outlet. The heat-conducting pipe is spirally arranged on the outer wall of the cavity seat, and one end of the heat-conducting pipe is fixedly connected to the second hot and cold inlet, and the other end of the heat-conducting pipe is fixedly connected to the second hot and cold outlet.

[0008] As an improvement of this utility model, a heat-conducting channel is formed on the first heat-conducting plate, with a first hot and cold inlet at one end and a first hot and cold outlet at the other end.

[0009] As an improvement of this utility model, the support frame is an aluminum frame, the first heat-conducting plate and / or the second heat-conducting plate is a 316 steel plate, and the heat-conducting pipe is a 316 steel pipe.

[0010] As an improvement of this utility model, a first groove is provided on the support plate, and the first heat-conducting plate is embedded in the first groove. A second groove is provided on the support frame, and the second heat-conducting plate is embedded in the second groove.

[0011] As an improvement of this utility model, the two ends of the first heat-conducting plate and the second heat-conducting plate respectively extend from the corresponding grooves to the outside of the support frame.

[0012] As an improvement of this utility model, a support column is fixedly connected to the side of the support plate facing the inner cavity.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] 1. By setting the cavity seat in the inner cavity formed by the support frame and setting heat-conducting plates and heat-conducting pipes around the cavity seat, the cavity seat can be directly cooled and heated without heating or cooling the entire template.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "first" and "second" used in the present invention are used to distinguish different objects, rather than to describe a specific order.

[0029] like Figures 1-3 As shown, this embodiment provides a rapid cooling and heating shoe sole mold, including a support frame 10. The support frame 10 is used to replace the core plate or template with a cavity in a traditional shoe sole mold. The support frame 10 is preferably an aluminum frame, which has relatively good thermal conductivity and helps to reduce the overall weight of the mold. The support frame 10 is a square frame, and the side plates together form an inner cavity. A support plate 11 is integrally connected to one side of the support frame 10. The support plate 11 covers the opening of the inner cavity at the corresponding position. Of course, the support plate 11 can also be fixedly connected to the support frame 10 by welding or other methods.

[0030] The support plate 11 has a feed port, and a cavity seat 20 located in the inner cavity is integrally connected to the periphery of the feed port. Of course, the cavity seat 20 can also be fixedly connected to the support plate 11 by welding or other means. The integrally connected support plate 11, cavity seat 20 and support frame 10 can be obtained by extrusion molding or 3D printing, etc. The wall thickness should be as small as possible while ensuring the support strength to improve the heat conduction efficiency.

[0031] Preferably, a support column 14 is fixedly connected to the side of the support plate 11 facing the inner cavity to improve its support strength.

[0032] The cavity seat 20 has a cavity communicating with the material inlet for molding the shoe sole. The number of material inlets and cavity seats 20 can be determined according to actual needs, but the number of both is the same and corresponds one-to-one. In this embodiment, there are two material inlets and two cavity seats 20, corresponding to the two soles of the same pair of shoes. A first heat-conducting plate 30 covering the material inlet is detachably fixedly connected to the support plate 11. A second heat-conducting plate 40 corresponding to the cavity is detachably fixedly connected to the side of the support frame 10 away from the support plate 11. Heat-conducting pipes 21 are arranged around the outer wall of the cavity seat 20. It should be noted that, in order to more clearly illustrate the corresponding structure, Figures 1-3 In the diagram, only one heat-conducting plate and heat-conducting pipe 21 are shown next to one of the cavity seats 20, while the heat-conducting plate and heat-conducting pipe 21 next to the other cavity seat 20 are hidden.

[0033] The specific detachable connection structure of the first heat-conducting plate 30 and the second heat-conducting plate 40 can be a conventional structure, such as a fixed connection by bolts, which will not be described in detail here. The heat-conducting pipe 21 has two ports for direct or indirect connection to a heating source or cooling source during use. In this embodiment, the second heat-conducting plate 40 is provided with a second hot and cold inlet 41 and a second hot and cold outlet 42. The heat-conducting pipe 21 is spirally arranged on the outer wall of the cavity seat 20, and one end of the heat-conducting pipe 21 is fixedly connected to the second hot and cold inlet, and the other end of the heat-conducting pipe 21 is fixedly connected to the second hot and cold outlet. That is, both ends of the heat-conducting pipe 21 are fixedly connected to the second heat-conducting plate 40 and are respectively connected to the second hot and cold inlet 41 and the second hot and cold outlet 42 one-to-one. In use, the second hot and cold inlet 41 is connected to the heating steam supply device and the cooling liquid supply device through a reversing valve, and the second hot and cold outlet 42 is connected to the steam recovery device and the cooling liquid recovery device through another reversing valve, thereby realizing heating and cooling. It should be noted that the reversing valve, heating steam supply device, cooling liquid supply device, steam recovery device, and cooling liquid recovery device mentioned above and below are not part of the shoe sole mold provided in this embodiment, and should be configured separately if needed.

[0034] The first heat-conducting plate 30 has an insertion part 31 that penetrates into the corresponding cavity, used to close the corresponding cavity and form the upper surface of the shoe sole. That is, the contour shape of the surface of the insertion part 31 facing the second heat-conducting plate 40 needs to be consistent with the upper surface of the formed shoe sole. The first heat-conducting plate 30 also has a heat-conducting channel, which passes through the insertion part 31 and its insertion part 31 is arranged in an S-shape. One end of the heat-conducting channel forms a first hot and cold inlet 32, and the other end forms a first hot and cold outlet 33. In use, the first hot and cold inlet 32 ​​is connected to a heating steam supply device and a coolant supply device respectively through a reversing valve, and the first hot and cold outlet 33 is connected to a steam recovery device and a coolant recovery device respectively through another reversing valve, thereby realizing heating and cooling. The second heat-conducting plate 40 is provided with heat-conducting fins 41, which abut against the cavity seat 20 to improve the heat conduction effect.

[0035] Preferably, in this embodiment, the first heat-conducting plate 30 and / or the second heat-conducting plate 40 are 316 steel plates, and the heat-conducting pipe 21 is a 316 steel pipe, so as to avoid deformation of the heat-conducting plate and the heat-conducting pipe 21 during use while ensuring thermal conductivity.

[0036] Preferably, in this embodiment, a first recessed groove 12 is provided on the support plate 11, and the first heat-conducting plate 30 is embedded in the first recessed groove 12. A second recessed groove 13 is provided on the side of the support frame 10 away from the support plate 11, and the second heat-conducting plate 40 is embedded in the second recessed groove 13. This facilitates quick positioning of the heat-conducting plate and ensures that the side of the first heat-conducting plate 30 away from the second heat-conducting plate 40 does not protrude outward relative to the support plate 11, and the side of the second heat-conducting plate 40 away from the first heat-conducting plate 30 does not protrude outward relative to the support frame 10. This ensures that the support frame 10 can be directly used to replace the core plate or the template with a cavity in the traditional shoe sole mold without adjusting other structures of the mold.

[0037] In addition, the two ends of the first heat-conducting plate 30 and the second heat-conducting plate 40 extend from their respective sinks to the outside of the support frame 10.

[0038] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
