Description

Technical Field

[0001] The utility model relates to the technical field of rain boots processing moulds, in particular to a high-efficiency production mould for rain boots. Background Art

[0002] Rain boots refer to waterproof shoes worn on rainy days, and there are various types of rain boots. For example, they can be divided into rubber rain boots, PVC rain boots and EVA rain boots according to the material. In the process of producing and processing rain boots, the rain boots need to be injection molded with the help of corresponding rain boot processing molds.

[0003] For example, the publication number: CN219486290U, "A rain boot processing mold that is easy to remove", includes a base and a left mold arranged at the upper end of the base and a right mold arranged on the right side of the left mold, a limiting mechanism, the limiting mechanism is used to install and connect the right mold and the mounting block and the left mold and the mounting block, and the limiting mechanism drives the right mold and the left mold to form a disassembly structure at the upper end of the support platform, a fixed plate, the fixed plate is arranged at the upper ends of the left mold and the right mold, and the fixed plate is used to further limit the left mold and the right mold. The demolding after injection molding in this patent is a one-step demolding, that is, the left and right molds are demolded separately by translation. This demolding method generates large resistance during the demolding process, which is easy to damage the surface of the rain boots, affecting normal demolding, thereby reducing the production yield and increasing the production cost in disguise.

[0004] This case was created to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide a high-efficiency production mold for rain boots to solve the problems raised in the above background technology.

[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model is implemented through the following technical solutions: a high-efficiency rain boots production mold, including a bottom plate, the bottom plate is slidably connected with mold one and mold two, a wedge-shaped notch is opened on one side of mold one, and the notch is located at the fitting position of mold one and mold two, the bottom plate is fixed with a vertical plate, the vertical plate is located on the side of mold one with the notch and is parallel to the side, a threaded rod is rotatably connected to the vertical plate, and a wedge block is threadedly connected to the end of the threaded rod close to mold one, and the wedge block is slidably connected to the notch.

[0009] Preferably, the threaded rod is provided with a limit block, the limit block is located on both sides of the vertical plate, the limit block away from the mold is provided with a turning handle, and the vertical plate is provided with a clamping column connected to the wedge block.

[0010] Preferably, a water tank is provided in the mold one and the mold two, the water tank is close to the heel side of the shoe last in the mold one and the mold two, and the water outlet and water inlet of the water tank are externally connected to a heat dissipation device.

[0011] Preferably, a cylinder is provided on the bottom plate, and the cylinder is located on the side of the mold 2 facing away from the mold 1, and the output end of the cylinder is connected to the mold 2.

[0012] Preferably, a guide block is fixedly provided around the bottom of the mold 1.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is a high-efficiency production mold for rain boots, which first cools the heel part of the shoe last through a water trough, and then utilizes the cooperation between the notch and the wedge block to slide the wedge block into the notch when the handle is turned. At this time, mold 2 is supported by the cylinder and cannot move, and mold 1 is "pried open" by the wedge block. The rain boots are demolded from the heel, and the heel has been cooled, making it easier to demold. The "prying open" causes mold 1 to move under the action of the guide block, and then the cylinder contracts to move mold 2 horizontally to complete the demolding, which has a better effect than one-step demolding.

[0021] The utility model is further described in detail below through the drawings and embodiments.

[0022] The utility model embodiment provides a high-efficiency production mold for rain boots, such as Figure 1-5As shown, it includes a bottom plate 1, which is slidably connected to a mold 1 2 and a mold 2 3. A wedge-shaped notch 4 is provided on one side of the mold 1 2, and the notch 4 is located at the fitting position of the mold 1 2 and the mold 2 3. The bottom plate 1 is fixed with a vertical plate 5, and the vertical plate 5 is located on the side of the mold 1 2 where the notch 4 is provided and is parallel to the side. A threaded rod 6 is rotatably connected to the vertical plate 5, and a wedge block 7 is threadedly connected to one end of the threaded rod 6 close to the mold 2, and the wedge block 7 is slidably connected to the notch 4.

[0023] The heel part of the shoe last is first cooled by the water tank 10, and then the notch 4 and the wedge block 7 are used to cooperate with each other, and the wedge block 7 is slid into the notch 4 when the handle 9 is turned. At this time, the mold 2 3 is supported by the cylinder 11 and cannot move, and the mold 1 2 is "pried open" by the wedge block. The rain boots are demoulded from the heel, and the heel has been cooled, making it easier to demould.

[0024] Reference Figure 2-3 , the threaded rod 6 is provided with a limit block 8, the limit block 8 is located on both sides of the vertical plate 5, the limit block 8 makes the threaded rod 6 not move when it is rotated by the turning handle 9, and only rotates away from the limit block 8 on the mold 2, and the vertical plate 5 is provided with a clamping column 13 connected to the wedge block 7. The structure of the clamping column 13 and the wedge block 7 is shown in the attached figure. Figure 5 The function of the clamping block 13 is to prevent the wedge block 7 from falling and to enable it to complete horizontal movement when it is acted upon by the threaded rod 6.

[0025] Reference Figure 4 A water tank 10 is provided in the mold 1 2 and the mold 2 3. The water tank 10 is close to the heel side of the shoe last in the mold 1 2 and the mold 2 3. The water outlet and the water inlet of the water tank 10 are externally connected to a heat dissipation device (not shown). The water tank 10 can cool the heel part first, which makes it easier to "pry open" and is not easy to damage the rain boots.

[0026] A cylinder 11 is provided on the bottom plate 1. The cylinder 11 is located on the side of the mold 2 3 away from the mold 1 2. The output end of the cylinder 11 is connected to the mold 2 3. A guide block 12 is fixed around the bottom of the mold 2. When the handle 9 is turned, the wedge block 7 slides into the notch 4. At this time, the mold 2 3 is supported by the cylinder 11 and cannot move. The mold 1 2 is "pried open" by the wedge block 7. The rain boots are demoulded from the heel, and the heel has been cooled, making it easier to demould. The "prying open" causes the mold 1 2 to move under the action of the guide block, and then the cylinder 11 contracts to move the mold 2 3 horizontally to complete the demoulding. Compared with the one-step demoulding effect, the demoulding effect is better.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
