The heating mold includes a base, a lower mold located on the base, and an upper mold located on the lower mold. The lower mold is equipped with three heating tubes. The heating tubes continuously provide heat to the lower mold. However, the heat from the heating tubes will be transferred in other directions, making the heat in the lower mold unstable, resulting in uneven heating of the lower mold and affecting production quality. At the same time, the heat from the heating tubes is transferred in other directions, causing a certain amount of energy waste. Utility Model Content

[0004] The utility model provides a heating mold for zipper processing, which reduces the heat in the lower mold from being transferred to other directions, thereby making the heating of the lower mold more stable and playing a certain energy-saving role.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] The following is combined with Figure 1-5 The utility model is further described as follows:

[0023] Combine Figure 1 and Figure 2 This embodiment discloses a heated mold for zipper processing, comprising a base 1, a lower mold 2 mounted on the base 1, an upper mold 3 mounted on the lower mold 2, and a heat-insulating layer 4 disposed between the base 1 and the lower mold 2. A placement slot 11 for mounting the lower mold 2 is defined on the base 1, and the heat-insulating layer 4 is disposed at the bottom of the placement slot 11. A zipper passage 5 for passing a zipper is defined between the lower mold 2 and the upper mold 3. The zipper passage 5 extends along the length of the upper mold 3 and the lower mold 2. The zipper passage 5 has an inlet end 51 at one end, through which the zipper enters, and an outlet end 52 at the other end.

[0024] A heating channel 21 is defined in the center of the lower mold 2, extending along its width. A heating tube is inserted into the channel 21. In this embodiment, three heating channels 21 are defined in the center of the lower mold 2, each containing a heating tube. These tubes heat the lower mold 2, heating the zipper as it enters the zipper channel 5. The thermal insulation layer 4 reduces the amount of heat transferred from the lower mold 2 to the bottom of the placement slot 11.

[0025] Combine Figure 1 、 Figure 2 and Figure 3The heat-insulating layer 4 includes a plurality of heat-insulating members 41 for supporting the lower mold 2, and a heat-insulating gap 42 formed between the base 1 and the lower mold 2 by supporting the plurality of heat-insulating members 41. In this embodiment, two heat-insulating members 41 are provided and are respectively placed at the bottom of both ends of the lower mold 2. The two heat-insulating members 41 raise the bottom surface of the lower mold 2, so that a heat-insulating gap 42 is formed between the bottom surface of the lower mold 2 and the bottom of the placement groove 11. The lower mold 2 and the base 1 are both made of metal. When the lower mold 2 is in direct contact with the base 1, the heat in the lower mold 2 is easily transferred to the base 1. Therefore, under the joint action of the heat-insulating members 41 and the heat-insulating gap 42, the lower mold 2 and the base 1 cannot be in direct contact, thereby reducing the heat transferred from the lower mold 2 to the base 1. Since the heating tube needs to continuously heat the lower mold 2 and maintain a certain temperature, the heat transferred from the lower mold 2 to the base 1 is reduced, that is, the waste of energy is reduced, and the energy consumption required for the heating tube is reduced, thereby achieving an energy-saving effect.

[0026] When the height of the insulation gap 42 is too large, the air in the insulation gap 42 is easy to flow, making the insulation effect of the insulation gap 42 poor. Therefore, installation grooves 22 are opened at the bottom of both ends of the lower mold 2, and the insulation component 41 is installed in the installation groove 22, so that the height of the insulation gap 42 is smaller, and the air in the insulation gap 42 is not easy to flow, thereby making the insulation gap 42 have a better insulation effect.

[0027] The bottom surface of the heat insulating member 41 in this embodiment is flush with the bottom surface of the lower mold 2 , and a groove of one or two millimeters is dug in the middle of the placement groove 11 , thereby forming a heat insulating gap 42 with a relatively small height.

[0028] The end surface of the heat insulation member 41 close to the side wall of the placement groove 11 protrudes from the installation groove 22 and abuts against the side wall of the placement groove 11, so that the side wall of the lower mold 2 is spaced apart from the side wall of the placement groove 11, reducing the heat in the lower mold 2 from being transferred to the side wall of the placement groove 11.

[0029] In this embodiment, the thermal insulation member 41 is a rectangular parallelepiped made of wood. The rectangular parallelepiped structure is stable and fits tightly with the lower mold 2 and base 1. The regular rectangular parallelepiped structure facilitates machining, and the mounting groove 22 cooperates with the rectangular parallelepiped thermal insulation member 41, making the mounting groove 22 also easy to machine. Wood is low-cost, easy to machine into a rectangular parallelepiped, and has a low thermal conductivity, making the thermal insulation member 41 made of wood a good insulating material. Furthermore, wood has a certain toughness, capable of absorbing energy and resisting fracture within a certain range.

[0030] Combine Figure 1 and Figure 2The base 1 is provided with a gas channel 12 arranged along the width direction of the base 1 at the outlet end 52 corresponding to the zipper channel 5. An outlet channel 13 is provided between the gas channel 12 and the outlet end 52. The top outlet of the outlet channel 13 blows air to cool the zipper at the outlet end 52. In this embodiment, the gas channel 12 includes a first cooling channel 121 located at the bottom of the placement groove 11 and a second cooling channel 122 located on the side wall of the placement groove 11. The outlet channel 13 includes a first blowing channel 131 vertically connected to the first cooling channel 121 and a second blowing channel 132 vertically connected to the second cooling channel 122. Both the first blowing channel 131 and the second blowing channel 132 blow air to cool the zipper at the outlet end 52.

[0031] Combine Figure 2 and Figure 3 The heat insulating member 41 is provided with an avoidance hole 411 corresponding to the first blowing channel 131 to ensure the smooth flow of the first blowing channel 131 .

[0032] Combine Figure 4 and Figure 5 A first processing groove 23 is opened on the upper surface of the lower mold 2, and a second processing groove 31 is opened on the lower surface of the upper mold 3. The first processing groove 23 and the second processing groove 31 are combined to form a zipper channel 5.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
