Description

Technical Field

[0001] This utility model relates to the technical field of shoe upper shaping equipment, and more specifically to a shoe upper folding and shaping device for sports shoes. Background Technology

[0002] A shoe upper shaping machine is a piece of equipment specifically used in the shoe manufacturing industry. Its main function is to heat and shape shoe upper materials (such as leather, artificial leather, etc.) according to design requirements so that they can better conform to the shape of the shoe. Generally, a portion of the toe area is folded to shape the shoe upper. The existing shaping equipment, as shown in application number CN202422539906.2, "A shoe upper shaping machine", has two rows of components for hot shaping and cold shaping arranged opposite to each other, and adopts an adjustment structure to simultaneously adjust multiple groups of shoe uppers for processing at the same time, so as to improve efficiency. However, the aforementioned shoe upper shaping machine is only supported by the "lower shaping mold" when the shoe upper is placed, resulting in a small support surface and poor stability. Furthermore, during the pre-heat shaping process, the "first upper shaping mold" presses the shoe upper into the cavity of the "lower shaping mold". After heat treatment, the "first upper shaping mold" and the shoe upper sometimes adhere to each other, which may cause the shoe upper to shift. Utility Model Content

[0003] The purpose of this utility model is to provide a folding and shaping device for the upper of sports shoes in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a shoe upper folding and shaping device, comprising: The machine body and its mold base and hot press head; It also includes an extension plate, which is fixed to the outside of the mold base to support a portion of the shoe upper, and the extension plate does not obstruct the shoe upper from extending into the mold cavity of the mold base; The release aid component is located at the bottom of the hot press head, with a portion of the release aid component exposed. When the hot press head extends into the mold cavity and the release aid component is pressed, a portion of the release aid component elastically retracts into the hot press head. The release aid component is heat resistant.

[0005] As a preferred embodiment of this utility model, when the bottom end of the hot press head contacts the mold cavity, the release aid component is completely inside the hot press head.

[0006] As a preferred technical solution of this utility model, the detachment aid component includes a compression groove disposed in the hot press head, a retraction groove disposed at the bottom end of the compression groove, a spring fixed in the retraction groove that moves up and down elastically, a shaft fixed to the bottom end of the spring, and a pad fixed to the bottom end of the shaft. The compression groove connects to the retraction groove, the shaft moves within the compression groove and the retraction groove, and the pad moves within the retraction groove.

[0007] As a preferred technical solution of this utility model, the detachment aid component further includes a sliding groove disposed in the compression groove and universal balls fixed on the outside of the shaft. The rolling end of the universal balls is fitted in the sliding groove, and multiple sets of the shaft and universal balls are provided in a one-to-one correspondence.

[0013] like Figures 1-2 As shown, this utility model proposes: a sports shoe upper folding and shaping device, comprising a machine body 1 and a mold base 2 and a hot press head 3 on it; the machine body 1 can be "CN202422539906.2" proposed in the background art above, and the mold base 2 and the hot press head 3 can be a "lower shaping mold" and a "first upper shaping mold" respectively for application; It also includes an extension plate 4, which is fixed to the outside of the mold base 2 to support a part of the shoe upper. The extension plate 4 does not obstruct the shoe upper from extending into the mold cavity of the mold base 2. The extension plate 4 is fixed on the lower right side of the mold base 2. When the toe part of the shoe upper is placed at the top of the mold base 2, the other parts of the shoe upper can be fitted and supported at the extension plate 4, thereby increasing the support position and improving the stability of the placement. The release aid component 5 is located at the bottom of the hot press head 3, with a portion of the release aid component 5 exposed. When the hot press head 3 extends into the mold cavity and the release aid component 5 is pressed, a portion of the release aid component 5 elastically retracts into the hot press head 3. The release aid component 5 is heat-resistant. The release aid component 5 is positioned near the center of the bottom of the hot press head 3. When the hot press head 3 presses the shoe upper into the mold cavity of the mold base 2, the hot press head 3 shapes the shoe upper in conjunction with the mold cavity. After shaping, the hot press head 3 moves upward. At the moment of upward movement, a portion of the release aid component 5 elastically supports the shoe upper, thus ensuring that the shoe upper detaches from the hot press head 3, greatly reducing the possibility of misalignment and improving the accuracy of shaping.

[0014] When the bottom end of the hot press head 3 contacts the mold cavity, the release aid component 5 is completely inside the hot press head 3. When the hot press head 3 extends into the mold cavity and the bottom end of the hot press head 3 contacts the shoe upper or the bottom end of the inner wall of the mold cavity, part of the release aid component 5 is not exposed, reducing obstruction factors. This can better ensure the shaping effect of the hot press head 3 on the shoe upper inside the mold cavity.

[0015] The extension plate 4 is made of plastic or stainless steel, and is highly durable.

[0016] The specific structure of the detachment aid component 5 is shown below: The detachment aid assembly 5 includes a compression groove 51 disposed in the hot press head 3, a retraction groove 52 disposed at the bottom end of the compression groove 51, a spring 53 fixed in the retraction groove 52 that moves up and down elastically, a shaft 54 ​​fixed to the bottom end of the spring 53, and a pad 55 fixed to the bottom end of the shaft 54. The compression groove 51 is connected to the retraction groove 52, the shaft 54 ​​moves within the compression groove 51 and the retraction groove 52, and the pad 55 moves within the retraction groove 52. Spring 53 can be a cylindrical helical spring. A retraction groove 52 and a compression groove 51 are sequentially connected inward from the bottom end of the hot press head 3. The top end of the spring 53 is fixed at the top end of the compression groove 51, and the bottom end of the spring 53 is fixed at the top end of the shaft 54. The shaft 54 ​​is partially located in the compression groove 51 to provide stable vertical guidance. The bottom end of the shaft 54 ​​is fixed to the pad 55. When the hot press head 3 moves downward, the pad 55 is contacted and subjected to force. The elastic force of the spring 53 drives the shaft 54 ​​and the pad 55 to move upward, so that the pad 55 is completely placed into the retraction groove 52. When the hot press head 3 moves upward, the spring 53 provides elastic support to the pad 55 to provide elastic pressure to the shoe upper.

[0017] Furthermore, the detachment aid component 5 also includes a slide groove 56 disposed in the compression groove 51 and universal balls 57 fixed to the outside of the shaft 54. The rolling end of the universal balls 57 is attached to the slide groove 56. The shaft 54 ​​and the universal balls 57 are provided in multiple sets corresponding to each other. The universal balls 57 are fixed on the upper side of the shaft 54, and a strip-shaped slide with the ends facing the slide groove 56 is provided in the compression groove 51. The universal balls 57 move by adhering to the strip-shaped slide groove 56, which can improve the stability of the shaft 54 ​​when it moves up and down. The inner side of the strip-shaped slide groove 56 can also be glued and fixed with adhesive (such as polyurethane glue). The rubber layer adheres to the movement of the universal balls 57 by the rubber layer, which improves the compression stability and further increases the stability of the shaft 54 ​​displacement.

[0018] Among them, the multiple sets of universal ball bearings 57 and grooves 56 are all evenly distributed in a ring; such as Figure 2 As shown, two sets of universal ball bearings 57 are symmetrically arranged on the left and right sides of the shaft 54, and two sets of sliding grooves 56 are symmetrically arranged on the corresponding left and right sides to improve the uniformity of support and thus improve the stability of the displacement of the shaft 54.

[0019] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
