Description

Technical Field

[0001] This utility model belongs to the technical field of heating equipment, and in particular relates to a heating device for foam molding of shoe soles. Background Technology

[0002] In the shoe sole manufacturing industry, foam molding is a commonly used production process. Foam molding involves heating the sole material to a certain temperature, causing it to expand and solidify within a mold, thereby forming a sole with properties such as lightweight and good elasticity. However, traditional shoe sole foam molding heating devices have the following shortcomings during use:

[0003] 1. In traditional heating devices, the distance between the heating plate and the mold is fixed during the heating process, which cannot adapt to shoe sole molds of different sizes and shapes, thus limiting the applicability of the heating device. At the same time, the mold dissipates heat slowly after use. In addition, traditional heating devices are not well designed in terms of heat dissipation and insulation, which can easily lead to heat loss and energy waste, and also pose a potential threat to the safety of operators.

[0004] Therefore, we propose a heating device for foam molding of shoe soles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fixed distance between the heating plate and the mold in traditional heating devices, which cannot adapt to shoe sole molds of different sizes and shapes, thus limiting the applicability of the heating device. In addition, the mold dissipates heat slowly after use. Furthermore, traditional heating devices are poorly designed in terms of heat dissipation and insulation, which can easily lead to heat loss and energy waste, and also pose a potential threat to the safety of operators. Therefore, this invention proposes a heating device for shoe sole foaming molding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heating device for foam molding of shoe soles, comprising:

[0008] The machine body has a support frame fixedly connected to its upper end, a hydraulic cylinder fixedly connected to its upper end, the output end of the hydraulic cylinder passing through the support frame and fixedly connected to a pressure plate, a plurality of connecting columns fixedly connected to the lower end of the pressure plate, a first mounting plate fixedly connected to the lower end of the connecting columns, and a second mounting plate fixedly connected to the middle part of the upper end of the machine body.

[0009] The molding assembly includes an upper molding mold that is bolted to the lower end of a first mounting plate, and a lower molding mold that is bolted to the upper end of a second mounting plate, for foam molding of the shoe sole;

[0010] The heating assembly includes heating plates respectively installed at the lower end of the upper molding mold and the upper end of the lower molding mold, which are used to heat the foaming material. Heating chambers are fixedly connected to the upper end of the first mounting plate and the lower end of the second mounting plate.

[0011] An adjustment component is installed inside the heating chamber and is used to adjust the position of the heating plate.

[0012] In one possible design, the adjustment assembly includes a limiting frame fixedly installed inside the heating chamber. Connecting frames are fixedly connected to the outer walls on both sides of one end of the two heating plates. A lead screw is rotatably connected to one side of the limiting frame, and a limiting rod is fixedly connected to the other side of the limiting frame. The outer wall of the lower end of the lead screw is threadedly connected to the connecting frame, and the limiting rod is slidably connected to the connecting frame, for adjusting the distance between the two heating plates and the upper forming mold and the lower forming mold, respectively.

[0013] In one possible design, heat dissipation vents are provided at the rear ends of both heating chambers, and heat insulation plates are fixedly connected to the inner walls of both the first mounting plate and the second mounting plate.

[0014] In one possible design, the upper end of the lead screw passes through the heating chamber and is fixedly connected to a handle for driving the lead screw to rotate.

[0015] In one possible design, guide posts are fixedly connected to both sides of the upper end of the body, and the two sides of the pressure plate are slidably connected to the guide posts to limit the pressure plate.

[0016] In one possible design, a protective door is rotatably connected to the front end of the body, and support legs are fixedly connected to the four corners of the lower surface of the body.

[0017] In this application, during use, after the device is started, the hydraulic cylinder begins to work, and its output end pushes the pressure plate downward. The pressure plate is fixedly connected to the first mounting plate through a connecting column, thus causing the first mounting plate and the upper forming mold installed below it to move downward together. At the same time, the second mounting plate at the upper end of the machine body remains stationary, and the lower forming mold at its upper end remains in its original position. When the upper and lower forming molds and the lower forming mold are closed, the gap between them forms a mold cavity for foaming the shoe sole. At this time, the heating component begins to work. Heating plates are respectively installed at the lower end of the upper forming mold and the upper end of the lower forming mold, and are adjusted by the adjusting component in the heating cavity. The lead screw in the adjusting component is driven to rotate by the handle. The rotation of the lead screw causes the screw to rotate. The connecting frame of the grooved joint drives the heating plate to move up and down under the guidance of the limiting frame and the limiting rod, thereby precisely adjusting the distance between the heating plate and the mold to adapt to different types of molds. At the same time, the design includes a component that can separate the heating plate from the mold, which can accelerate the heat dissipation of the mold. The heating plate heats the foaming material in the mold cavity, causing it to expand and solidify. During the heating process, the heat dissipation vents allow the heat in the heating cavity to dissipate appropriately to prevent overheating. Meanwhile, the heat insulation plate effectively isolates the heat exchange between the heating cavity and other internal components of the machine, ensuring efficient heat utilization and operator safety. After the sole foaming and molding is completed, the hydraulic cylinder reverses its operation, pushing the pressure plate and the upper molding mold upwards, making it easy to remove the molded sole.

[0018] In this utility model, the heating device for foam molding of shoe soles allows for flexible adjustment of the distance between the heating plate and the mold through precise adjustment of the components, thereby adapting to shoe sole molds of different sizes and shapes. At the same time, separating the heating plate from the mold can accelerate the heat dissipation of the mold, improve its practicality, and greatly broaden the application range of the heating device. The heat insulation design in the heating chamber and the reasonable setting of the heat dissipation vents not only prevent excessive heat loss but also ensure the effective utilization of heat and reduce energy consumption.

[0019] In this utility model, the heating device for foam molding of shoe soles effectively isolates the high-temperature heating components from the operator through the use of heat insulation plates, reducing the safety risks during operation. The components of the device are compact and reasonably designed, which facilitates daily maintenance and troubleshooting, reduces maintenance costs, and is highly practical.
