Abstract
Description
Technical Field
[0001] This utility model relates to the field of insole production technology, specifically a foaming device for producing sports shoe insoles. Background Technology
[0002] Insoles are widely used in the footwear industry, for health purposes, and for special functions; they are generally divided into two types: footwear factory-application insoles and market-commercial insoles. Footwear factory-application insoles are mainly designed to fit the outsole and midsole of shoes, creating corresponding shapes; size charts are made according to the last or upper, and the corresponding shapes are produced. Market-commercial insoles are products designed by developers and sold directly in the market.
[0003] Some insoles require foaming during the production process. Currently, foaming machines require manual loading and unloading, and the molds are often compacted using hydraulic rods. However, current foaming machines lack any protective structures, which can easily lead to accidents if operators mishandle the machine and fail to remove their hands from the mold in time. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a foaming device for producing sports shoe insoles, which solves the problem that current foaming machines lack any protective structure, making it easy for accidents to occur if operators misoperate and fail to promptly remove their hands from the mold.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a foaming device for producing sports shoe insoles, comprising a base, with uprights vertically fixedly connected to both sides of the upper surface of the base, and a fixed seat horizontally fixedly connected to the top of the two uprights. An upper mold mounting plate is fixedly connected to the lower surface of the fixed seat, and a connecting rod is hinged to the front end of the lower surface of the upper mold mounting plate. A lower mold mounting plate is provided below the upper mold mounting plate, and the bottom end of the connecting rod is hinged to the middle of the upper surface of the lower mold mounting plate.
[0006] Furthermore, an upper template is detachably mounted on the lower surface of the upper mold mounting plate, and a lower template is detachably mounted on the upper surface of the lower mold mounting plate.
[0007] Furthermore, a hydraulic rod is vertically fixedly connected to the upper surface of the base, and a connecting plate is horizontally fixedly connected to the top end of the hydraulic rod.
[0008] Furthermore, the lower mold mounting plate is laterally slidably connected to the upper surface of the connecting plate.
[0009] Furthermore, a start button is provided on both sides of the front end of the base.
[0010] Furthermore, a plurality of support pads are fixedly connected to the bottom end of the base.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This foaming device for producing sports shoe insoles, by setting a connecting rod, allows the connecting plate to move up or down via a hydraulic rod during operation. When it descends, the lower mold mounting plate, which is slidably connected to the connecting plate, also moves down synchronously. Under the action of the connecting rod of a fixed length, the lower mold mounting plate will move forward, and vice versa. With this structure, during the entire process of placing materials on the lower mold plate, the worker's hands are located outside the device, thus preventing the situation where the hand is not pulled out in time due to misoperation, thereby improving the safety performance of the device.

[0015] In the diagram: 1-base, 2-upper pole, 3-fixed seat, 4-hydraulic rod, 5-connecting plate, 6-lower mold mounting plate, 7-lower template, 8-upper mold mounting plate, 9-upper template, 10-connecting rod, 11-start button, 12-support pad. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a foaming device for producing sports shoe insoles, including a base 1, with uprights 2 vertically fixedly connected to both sides of the upper surface of the base 1, and fixed seats 3 horizontally fixedly connected to the top of the two uprights 2. An upper mold mounting plate 8 is fixedly connected to the lower surface of the fixed seat 3, and a connecting rod 10 is hinged to the front end of the lower surface of the upper mold mounting plate 8. A lower mold mounting plate 6 is provided below the upper mold mounting plate 8, and the bottom end of the connecting rod 10 is hinged to the middle of the upper surface of the lower mold mounting plate 6.
[0018] The upper template 9 is detachably mounted on the lower surface of the upper mold mounting plate 8, and the lower template 7 is detachably mounted on the upper surface of the lower mold mounting plate 6.
[0019] A hydraulic rod 4 is vertically fixed to the upper surface of the base 1, and a connecting plate 5 is horizontally fixed to the top of the hydraulic rod 4.
[0020] The lower mold mounting plate 6 is laterally slidably connected to the upper surface of the connecting plate 5.
[0021] When the device is in operation, the hydraulic rod 4 drives the connecting plate 5 to move up or down. When it moves down, the lower mold mounting plate 6, which is slidably connected to the connecting plate 5, also moves down synchronously. Under the action of the connecting rod 10 of fixed length, the lower mold mounting plate 6 will move forward, and vice versa. With this structure, when the worker is loading and unloading materials, their hands are located outside the device throughout the entire process of placing the materials on the lower mold plate 7. This prevents the situation where the hands are not pulled out in time due to misoperation, thus improving the safety performance of the device.
[0022] During the downward movement of the lower mold mounting plate 6, since the length of the connecting rod 10 is fixed, its lower end will also move towards the position of its top vertical direction as it moves downward, thereby driving the lower mold mounting plate 6 to move synchronously.
[0023] A start button 11 is provided on both sides of the front end of the base 1.
[0024] The two start buttons 11 must be pressed together to control the device to close, which also plays a certain protective role, preventing the operator from leaving their hands in the mold during actual operation.
[0025] Multiple support pads 12 are fixedly connected to the bottom of the base 1.
[0026] Multiple support pads 12 all provide support.
[0027] When the device is in operation, the hydraulic rod 4 drives the connecting plate 5 to move up or down. When it moves down, the lower mold mounting plate 6, which is slidably connected to the connecting plate 5, also moves down synchronously. Under the action of the connecting rod 10 of fixed length, the lower mold mounting plate 6 will move forward, and vice versa. With this structure, when the worker is loading and unloading materials, their hands are located outside the device throughout the entire process of placing the materials on the lower mold plate 7. This prevents the situation where the hands are not pulled out in time due to misoperation, thus improving the safety performance of the device.
