Description

Technical Field

[0001] This utility model relates to the field of shoe sole mold technology, specifically a shoe mold for processing the soles of men's shoes. Background Technology

[0002] Men's shoe soles are often produced using injection molding. The shoe molds used typically include an upper mold and a lower mold that work together. The upper and lower molds are connected on one side by a hinge, and the other side is equipped with a handle for easy opening and closing.

[0003] After the sole is injection molded, due to the negative pressure that may be formed in the mold cavity and the adhesion between the sole material and the surface of the mold cavity, there is often a large mold opening resistance between the upper and lower molds.

[0004] In traditional operations, workers need to manually apply considerable force to the handle to open the mold, which is not only time-consuming and labor-intensive, but also increases labor intensity and affects production efficiency.

[0005] Therefore, we propose a shoe mold for processing the soles of men's shoes. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a shoe mold for processing the soles of men's shoes. Through a clever inclined plane and spring structure, the lateral impact force is converted into a vertical ejection force, achieving a labor-saving and efficient mold opening method, which can effectively solve the problems in the background technology.

[0007] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shoe mold for processing the sole of men's shoes, comprising a lower mold and an upper mold, wherein the upper mold and the lower mold are hinged on one side, a second handle is fixedly installed on the left side of the outer surface of the front end of the upper mold, and a first handle is fixedly installed on the right side of the outer surface of the front end of the lower mold. A mold opening auxiliary structure is provided in the middle of the front end of the lower mold, the mold opening auxiliary structure comprising a first slide groove, a second slide groove, a pressure slider, a collision block, a limiting groove, a pressure inclined surface, a spiral spring, a top material block, a pressure block, a pressure inclined surface, a lifting stroke limiting groove and a limiting pin, wherein the first slide groove is opened in the middle of the outer surface of the front end of the lower mold, the second slide groove is opened in the middle of the front end of the upper outer surface of the lower mold, and the lower end of the second slide groove is connected to the middle of the upper end of the first slide groove.

[0008] Preferably, the helical spring is located in the first slide groove, the helical spring is fixed between the end of the first slide groove and the outer surface of the rear end of the pressure slider, the impact block is fixed to the front end of the upper outer surface of the pressure slider, and the outer wall of the pressure slider is slidably connected to the first slide groove.

[0009] Preferably, the limiting groove is formed on the outer surface of the upper end of the pressure slider near the end of the helical spring, and the pressure inclined surface is formed on the front side of the limiting groove; the outer surface of the rear end of the pressure slider is elastically connected to the end of the first slide groove through the helical spring.

[0010] Preferably, the outer wall of the top material block and the second slide groove are slidably connected, the pressure block is fixed on the lower outer surface of the top material block, the pressure inclined surface is opened on the front outer surface of the pressure block, the limiting pin is fixed in the middle and upper part of the second slide groove, the lifting stroke limiting groove is opened on one side outer surface of the top material block, and the lifting stroke limiting groove extends to the other side outer surface of the top material block.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a shoe mold for processing the sole of men's shoes, which has the following beneficial effects: 1. This shoe mold for processing the sole of men's shoes, through the setting of the mold opening auxiliary structure, utilizes the inclined plane transmission mechanism to effectively convert the horizontal striking force of the operator on the impact block into the vertical upward ejection force of the ejector block during mold opening. This allows the vacuum adsorption force and material adhesion force between the upper and lower molds to be easily broken without the need for brute force, reducing the operating force required for mold opening, alleviating the labor intensity of workers, and improving mold opening efficiency.

[0014] 2. In this shoe mold for processing the sole of men's shoes, after the pressure slider and the impact block complete the lifting action, they are driven by the elastic restoring force provided by the helical spring to automatically reset to the initial position, ready for the next operation; while the top block falls naturally down along the second slide under its own gravity to reset. The reset mechanism is achieved by the mechanical structure itself, without the need for an additional power source, and the structure is simple and reliable. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a shoe mold for processing the sole of men's shoes, including a lower mold 1 and an upper mold 2, which are hinged to one side of the upper mold 2 and the lower mold 1. A second handle 4 is fixedly installed on the left side of the front outer surface of the upper mold 2, and a first handle 3 is fixedly installed on the right side of the front outer surface of the lower mold 1, to facilitate the holding and opening / closing operation of the mold. An opening auxiliary structure 5 is provided in the middle of the front end of the lower mold 1.

[0022] The mold opening auxiliary structure 5 includes a first slide 6, a second slide 7, a pressure slider 8, a collision block 9, a limiting groove 10, a pressure inclined surface 11, a coil spring 12, an ejector block 13, a pressure block 14, a pressure inclined surface 15, a lifting stroke limiting groove 16, and a limiting pin 17. The first slide 6 is horizontally opened in the middle of the front outer surface of the lower mold 1. The second slide 7 is vertically opened in the middle of the front end of the upper outer surface of the lower mold 1, and the lower end of the second slide 7 is connected to the middle of the upper end of the first slide 6.

[0023] The helical spring 12 is housed in the first slide groove 6, with its front end fixedly connected to the outer surface of the rear end of the pressure slider 8 and its rear end fixedly connected to the inner wall of the end of the first slide groove 6. The impact block 9 is fixedly installed on the front end of the upper outer surface of the pressure slider 8. The outer wall of the pressure slider 8 and the inner wall of the first slide groove 6 are in sliding fit, allowing the pressure slider 8 to slide horizontally within the first slide groove 6 and compress or release the helical spring 12.

[0024] A limiting groove 10 is formed on the upper outer surface of the pressure slider 8 near the end of the helical spring 12. A pressure inclined surface 11 is formed on the front inner wall of the limiting groove 10. The rear outer surface of the pressure slider 8 is elastically connected to the end of the first slide groove 6 through the helical spring 12.

[0025] The outer wall of the top material block 13 is slidably connected to the inner wall of the second slide groove 7, allowing it to slide up and down along the second slide groove 7. The pressure block 14 is fixedly installed on the lower outer surface of the top material block 13. A pressure-bearing inclined surface 15 is formed on the front outer surface of the pressure block 14. A limiting pin 17 is fixedly installed on the upper middle inner wall of the second slide groove 7. A lifting stroke limiting groove 16 is vertically formed on one outer surface of the top material block 13 and extends to the other outer surface of the top material block 13. The top material block 13 is slidably connected to the outer wall of the limiting pin 17 via the lifting stroke limiting groove 16, thereby limiting the lifting stroke of the top material block 13 and preventing it from detaching.

[0026] The lower front end of the pressure block 14 extends into the limiting groove 10 of the pressure slider 8. The inclination angle of the pressure inclined surface 11 and the pressure inclined surface 15 are matched. When the pressure slider 8 is struck by an external force and slides towards the helical spring 12 (i.e., backward), the pressure inclined surface 11 will press against the pressure inclined surface 15, thereby driving the pressure block 14 and the top block 13 to slide upward along the second slide groove 7.

[0027] When the helical spring 12 is in its initial state of natural extension, the upper end face of the ejector block 13 is not higher than the upper forming surface of the lower mold 1, so as to ensure that the tight closure of the upper mold 2 and the lower mold 1 is not affected when the mold is closed.

[0028] The working principle of this utility model is as follows: When the mold needs to be opened after the sole injection molding, the operator uses a tool (such as a rubber mallet) to horizontally strike the impact block 9. The impact block 9 drives the pressure slider 8 to slide backward along the first slide groove 6, compressing the coil spring 12. During this process, the pressure inclined surface 11 on the pressure slider 8 and the pressure inclined surface 15 on the pressure block 14 move relative to each other. Utilizing the action of the inclined surfaces, the horizontal movement of the pressure slider 8 is converted into a vertical upward thrust on the pressure block 14. The pressure block 14 drives the ejector block 13 to move upward along the second slide groove 7. The upper end face of the ejector block 13 eventually protrudes from the upper surface of the lower mold 1, thereby acting on the upper mold 2 or the molded sole, breaking the vacuum suction force and material adhesion force between the upper and lower molds, and assisting in the easy opening of the mold.

[0029] After the mold opening action is completed, the impact force on the impact block 9 is removed. The pressure slider 8 automatically returns to its initial position under the restoring force of the helical spring 12. The ejector block 13 slides downward along the second slide groove 7 under its own gravity, and returns to its initial position through the guidance of the lifting stroke limit groove 16 and the limit pin 17, that is, the upper end surface of the ejector block 13 is not higher than the upper end surface of the lower mold 1, thus preparing for the next mold closing and forming.
