Description

Technical Field

[0001] This utility model relates to the field of shoe sole mold technology, and in particular to a PU-coated shoe sole mold. Background Technology

[0002] Shoe sole molds are tools used to manufacture shoe soles. PU-coated shoe sole molds utilize the principle of vacuum adsorption to adsorb PU coating and other materials onto the surface of the sole mold, making it fit the shape of the sole mold, which facilitates subsequent one-piece molding.

[0003] Existing technologies, such as the utility model with publication number CN219311825U, are relevant to this application. This application relates to a shoe sole mold, belonging to the mold field. It includes a base template, a clamping template, and a closing template. The clamping template is located between the base template and the closing template. The base template has a concave mold, and the closing template has a convex mold that mates with the concave mold. The clamping template has a die hole through which the convex mold passes. When the clamping template and the closing template are closed on the base template, a mold cavity for making the shoe sole is formed between the concave mold and the convex mold. An elastic protective film for forming on the outer surface of the shoe sole is placed between the clamping template and the base template. A vacuum cavity is formed inside the base template, and the cavity wall of the vacuum cavity has several vacuum holes communicating with the concave mold. A vacuum valve communicating with the vacuum cavity is provided on the outer wall of the base template. This application can achieve a smoother surface for the formed shoe sole.

[0004] In daily work, it has been found that existing PU-coated shoe sole molds usually require operators to manually open and close the molds during use. This is inconvenient and results in low overall operating efficiency. Manual closing is also less precise and can easily lead to mold misalignment and component wear, which not only affects product accuracy but also shortens the mold's lifespan. Utility Model Content

[0005] The purpose of this invention is to solve the problems of manual mold opening and closing, cumbersome operation, and poor accuracy in the existing technology, and to propose a PU-coated shoe sole mold.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a PU-coated shoe sole mold, comprising a lower mold, a middle mold and an upper mold arranged sequentially above the lower mold, a vacuum hole provided inside the lower mold, a vacuum valve provided on one side of the lower mold, and an auxiliary device provided on the lower mold, the auxiliary device comprising two hollow seats fixed to one side surface of the lower mold, the upper mold having a rotating shaft fixedly connected to its surface, the rotating shaft being rotatably connected to the inner wall of the hollow seat, the middle mold having two rotating sleeves fixedly connected to its surface, each rotatably connected to the inner wall of the hollow seat, the rotating sleeves being through which the rotating shaft passes, and the lower mold having a drive unit one and a drive unit two respectively provided on both sides for controlling the rotation of the rotating sleeves and the rotating shaft. Through the above components, the rotating sleeves and the rotating shaft can be controlled to rotate by the drive unit one and the drive unit two, thereby realizing the automatic opening and closing of the middle mold and the upper mold, improving the overall practicality.

[0007] Preferably, the drive unit includes a cylinder fixed to one side surface of the lower mold. A rack is fixedly connected to the output end of the cylinder, and a gear is fixedly connected to the surface of the rotating sleeve. The gear meshes with the rack. By using the above components, when the cylinder is opened, the cylinder can drive the rack to move. The rack, in conjunction with the gear, can drive the rotating sleeve to rotate in the hollow seat, thereby facilitating the opening and closing of the middle mold.

[0008] Preferably, two rods are fixedly connected to one side surface of the lower mold, and the rods are slidably connected to the inner wall of the rack. Through the above-mentioned components, the two rods can improve the stability of the rack movement.

[0009] Preferably, the second drive unit includes a second cylinder fixed to one side surface of the lower mold. The output end of the second cylinder is fixedly connected to a second rack. The surface of the rotating sleeve is fixedly connected to a second gear. The second gear meshes with the second rack. By using the above components, when the second cylinder is opened, the second cylinder can drive the second rack to move. The second rack, in conjunction with the second gear, can drive the rotating shaft to rotate in the first hollow seat, thereby facilitating the opening and closing of the upper mold.

[0010] Preferably, two rods are fixedly connected to one side surface of the lower mold, and the rods are slidably connected to the inner wall of the rack. Through the above-mentioned components, the two rods can improve the stability of the movement of the rack.

[0011] Preferably, a locking assembly is provided on one side of the lower mold. The locking assembly includes a slide member that is slidably connected to the inner wall of the lower mold. A cylinder three is fixedly connected to one side surface of the lower mold. The output end of the cylinder three is fixedly connected to the surface of the slide member. Insert block one and insert block two are fixedly connected to the surface of the slide member. Hollow sleeve one and hollow sleeve two are fixedly connected to one side surface of the middle mold and the upper mold, respectively. Insert block one and insert block two are respectively inserted into the inner walls of hollow sleeve one and hollow sleeve two. By opening the cylinder three through the above components, the cylinder three can drive the slide member to move, so that insert block one and insert block two are respectively inserted into hollow sleeve one and hollow sleeve two, thereby realizing the locking operation.

[0012] Preferably, the length of the first insert is shorter than the length of the second insert, so that the second insert can be inserted into the hollow sleeve first through the above-mentioned components.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an auxiliary device, the rotating sleeve and rotating shaft can be controlled to rotate in the hollow sleeve 2 and hollow sleeve 1 respectively through the drive unit 1 and drive unit 2, thereby controlling the opening and closing of the middle mold and the upper mold. During the molding process, there is no need for manual opening and closing of the mold, ensuring opening and closing accuracy, reducing manual operation time, thereby shortening the entire production cycle and improving the overall practicality.

[0014] In this utility model, by setting a locking component, the cylinder three can drive the sliding part, the first insert and the second insert to move and insert into the hollow sleeve one and the second hollow sleeve, thereby realizing the locking operation of the middle mold and the upper mold and improving the overall ease of use.

[0018] Specifically, the auxiliary device 5 includes two hollow seats 53 and 54 fixed on one side surface of the lower mold 1. A rotating shaft 55 is fixedly connected to the surface of the upper mold 3, and the rotating shaft 55 is rotatably connected to the inner wall of the hollow seat 53. Two rotating sleeves 56 are fixedly connected to the surface of the middle mold 2, and are rotatably connected to the inner wall of the hollow seat 54 respectively. The rotating sleeves 56 allow the rotating shaft 55 to pass through. A drive unit 51 and a drive unit 52 for controlling the rotation of the rotating sleeves 56 and the rotating shaft 55 are respectively provided on both sides of the lower mold 1. The drive unit 51 includes a cylinder 511 fixed on one side surface of the lower mold 1, and the output end of the cylinder 511 is fixedly connected to... The device includes a rack 513, a gear 514 fixedly connected to the surface of a rotating sleeve 56, and a gear 514 meshing with the rack 513. Two rods 512 are fixedly connected to one side surface of the lower mold 1 and are slidably connected to the inner wall of the rack 513. The drive unit 52 includes a cylinder 521 fixedly attached to one side surface of the lower mold 1. A rack 523 is fixedly connected to the output end of the cylinder 521.

Two rods 522 are fixedly connected to one side surface of the lower mold 1 and are slidably connected to the inner wall of the rack 523.

[0019] In this embodiment: when cylinder 511 is opened, it can drive rack 513 to move. Rack 513, in conjunction with gear 514, can drive rotating sleeve 56 to rotate in hollow seat 54, facilitating the opening and closing of the middle mold 2. When cylinder 521 is opened, it can drive rack 523 to move.
