Description

Technical Field

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

[0002] The working principle of shoe sole foaming mold is mainly to inject liquid foaming material (such as polyurethane) into the mold under high temperature and high pressure environment, and make it foam through steam or other means inside the mold, and finally form a shoe sole with specific shape and performance.

[0003] Traditional shoe sole foaming molds are typically connected and fixed using bolts and other fasteners, resulting in cumbersome and inefficient operation. Furthermore, the lack of effective positioning and flipping mechanisms during mold opening and closing makes operation inconvenient and prone to damage. Therefore, a simple and easy-to-operate shoe sole foaming mold structure is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely on fasteners such as bolts for connection and fixation, which are cumbersome and inefficient. This invention proposes a foaming mold structure for shoe soles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shoe sole foaming mold structure includes a lower mold and an upper mold, wherein the upper mold rotates to the top of the lower mold;

[0007] The upper mold is fixed with a first fixing plate on its side, and the lower mold is fixed with a second fixing plate on its side. A set of connecting components for closing the lower mold and the upper mold is provided between the first fixing plate and the second fixing plate.

[0008] A set of matching components is provided between the lower mold and the upper mold, and the matching components are used to facilitate the positioning of the lower mold and the upper mold;

[0009] Two sets of lifting components are provided, both of which are located within the second fixed plate and are used to drive the upper mold to rotate at a certain angle.

[0010] In one possible design, the connecting assembly includes a matching block fixed to the bottom of a first fixing plate, a matching groove matching the matching block being formed at the top of the second fixing plate, a snap-fit ​​groove being formed inside the matching block, a first groove communicating with the matching groove being formed inside the second fixing plate, a snap-fit ​​block sliding inside the first groove, the snap-fit ​​block engaging with the snap-fit ​​groove, a snap-fit ​​spring being fixed to the side end of the snap-fit ​​block, and the side end of the snap-fit ​​spring being fixed inside the first groove.

[0011] In one possible design, the connecting assembly further includes a connecting rod fixed to the side end of the snap-fit ​​block, the side end of the connecting rod extending outward through the second fixing plate and fixed with a pull plate, and the snap-fit ​​spring being sleeved on the surface of the connecting rod.

[0012] In one possible design, each of the lifting components includes a second groove formed in the second fixed plate, in which a lifting block for lifting the first fixed plate is slidably disposed, the lifting block having a receiving groove, and a lifting spring fixed in the receiving groove, the side end of the lifting spring being fixed in the second groove.

[0013] In one possible design, the matching component includes two limiting blocks fixed to the top of the lower mold, and two limiting grooves are formed at the bottom of the upper mold, with the two limiting grooves respectively matching the two limiting blocks.

[0014] In one possible design, the first fixing plate has a gripping groove.

[0015] In this application, after the lower mold and the upper mold are closed, the matching block on the side of the first fixed plate is inserted into the matching groove. The matching block presses the inclined surface of the snap-fit ​​block, so that the snap-fit ​​block temporarily enters the first groove. Then the matching block is fully inserted into the matching groove. Because the snap-fit ​​block matches the snap-fit ​​groove, it is pushed into the snap-fit ​​groove by the elasticity of the snap-fit ​​spring, thereby fixing the position of the lower mold and the upper mold without the need for additional locking steps for the lower mold and the upper mold.

[0016] After foaming is complete, the connecting rod is moved by pulling the pull plate. The connecting rod moves the snap-fit ​​block back into the first groove, so that the snap-fit ​​block leaves the snap-fit ​​groove. The elasticity of the two lifting springs pushes the two lifting blocks to move upward. The two lifting blocks press the first fixed plate to move upward. The first fixed plate is pressed and causes the upper mold to flip upward. The upper mold can be flipped open by putting your hand into the grip groove.

[0017] Beneficial effects: In this utility model, the shoe sole foaming mold structure can easily realize the closed connection and separation of the lower mold and the upper mold by setting the connecting components, which is simple and quick to operate and improves work efficiency;

[0018] In this utility model, the shoe sole foaming mold structure, by setting matching components, can ensure the positioning accuracy of the lower mold and the upper mold when closed, and avoid quality problems caused by mold misalignment;

[0019] In this invention, by setting up a lifting component, the upper mold can be easily flipped, reducing the labor intensity of operators and improving the ease of use of the mold. Attached Figure Description
