Description

Technical Field

[0001] This application relates to the technical field of shoe sole processing, and in particular to a shoe sole mold that is easy to demold. Background Technology

[0002] Rubber shoe soles are made of natural or synthetic rubber and can withstand repeated bending, stretching, and compression without damage. They offer advantages such as high elasticity, comfort, and abrasion resistance. Rubber shoe soles are typically injection molded in one piece using a mold. After molding, a demolding tool is needed to remove the sole from the mold for further processing.

[0003] In related technologies, a shoe sole mold includes a first module, a second module, and a mold core disposed in the first module. The first module is provided with a first groove for accommodating the mold core, and the second module is provided with a second groove corresponding to the position of the first groove. When the first module and the second module are closed, the first groove and the second groove combine to form a mold cavity. Molten rubber is injected into the mold cavity, and after cooling, the shoe sole is formed.

[0004] However, the above-mentioned shoe sole mold requires manual demolding after the sole is formed. That is, after the first module and the second module are separated, workers need to manually insert tools into the first groove and peel the sole off the mold core. This is time-consuming, labor-intensive, and has low demolding efficiency, and needs to be improved. Utility Model Content

[0005] To improve the demolding efficiency of shoe soles, this application provides a shoe sole mold that facilitates demolding.

[0006] The shoe sole mold provided in this application, which facilitates demolding, adopts the following technical solution:

[0007] A shoe sole mold that facilitates demolding includes a first module, a second module, and a mold core disposed in the first module. The first module has a first groove for accommodating the mold core, and the second module has a second groove corresponding to the position of the first groove. When the first module and the second module are closed, the first groove and the second groove combine to form a mold cavity. The first module is provided with a demolding mechanism for pushing the mold core out of the first groove. The demolding mechanism includes a push plate movably disposed on the first module and an elastic element for driving the push plate to move towards the second module. The mold core is mounted on the push plate.

[0008] By adopting the above technical solution, when demolding the shoe sole is required, it is only necessary to control the separation of the first module and the second module. The elastic element can then push the push plate towards the second module, causing the mold core to move out of the first groove, thereby allowing the formed shoe sole to detach from the first groove. The worker only needs to separate the shoe sole from the mold core. The above demolding method does not require tools to be inserted into the first groove, providing a large operating space and high demolding efficiency.

[0009] Optionally, the elastic member comprises a plurality of reset springs abutting between the push plate and the first module, and the first module is provided with a guide column penetrating through the reset spring.

[0010] By adopting the above technical scheme, when the first module and the second module are combined, the reset spring is compressed and deformed by the extrusion of the push plate to generate an elastic force, and the elastic force can push the push plate towards the second module after the first module and the second module are separated, so that the mold core is automatically moved out of the first mold groove, and the structure is simple and the pushing effect is good.

[0011] The guide column plays a guiding and positioning role when the reset spring is stretched and contracted, so that the reset spring is not easy to slide or deviate relative to the first module, and the reset spring is not easy to be damaged due to excessive deformation, and the movement stability of the push plate and the mold core controlled by the reset spring is high.

[0012] Optionally, the side of the push plate facing the reset spring is provided with a stop column, and the stop column penetrates through the reset spring.

[0013] By adopting the above technical scheme, when the reset spring is deformed, the stop column can further control the deformation direction of the reset spring, so that the reset spring is not easy to deform in a direction other than its stretching and contraction, the service life of the reset spring is prolonged, and the stability of the demolding mechanism is high.

[0014] Optionally, the push plate comprises a pushing part and two movable parts provided on the side of the pushing part away from the elastic member, the first module is provided with a movable groove in sliding cooperation with the movable part and a through hole in sliding cooperation with the pushing part, and the sliding direction of the movable part along the movable groove and the sliding direction of the pushing part along the through hole are parallel to the stretching direction of the elastic member.

[0015] By adopting the above technical scheme, when the push plate moves towards the second module, the movable part can slide along the movable groove, and the pushing part can slide along the through hole, the movable groove limits the movement track of the movable part, and the through hole limits the movement track of the pushing part, so that the mold core is not easy to shake in a direction perpendicular to the stretching and contraction of the reset spring when the mold core is ejected, and the stability of the mold core and the sole during demolding operation is improved.

[0016] Optionally, the distance between the movable part and the second module is less than the distance between the mold core and the second module.

[0017] By adopting the above technical scheme, when the mold is combined, the second module will abut against the movable part rather than the mold core, so as to disperse the pressure of the second module on the mold core, so that the second module is not easy to damage the mold core, and the service life of the mold core is prolonged.

[0018] Optionally, the mold core is provided with a mounting block, the side of the mounting block away from the mold core is provided with a plurality of connecting rods, and the push plate is provided with a connecting hole in plug-in cooperation with the connecting rod.

[0019] By adopting the technical scheme, the mold core is detachably connected with the push plate through the connecting rod, when different styles of mold core need to be replaced, the mold core only needs to be moved away from the first type groove, so that the connecting rod is detached from the connecting hole, and different styles of mold core can be replaced, so that the style of the shoe sole is flexible and changeable.

[0020] Optionally, a connecting bolt threadedly matched with the connecting rod is arranged on the push plate, and a through hole corresponding to the connecting hole is arranged on the side wall of the first module away from the second module.

[0021] By adopting the technical scheme, when the connecting rod is inserted into the connecting hole, the connecting bolt can further fasten the connecting rod in the connecting hole, the stability of the connection between the connecting rod and the push plate is improved, and the stability of the mold core is further improved. When different styles of mold core need to be replaced, the connecting bolt only needs to be loosened by inserting a tool into the through hole, and then the connecting rod is pulled out of the connecting hole, so that the mold core is conveniently disassembled.

[0022] Optionally, a fixed block is arranged on one side of the push-moving part towards the movable part, a fixed groove for the fixed block to extend into is arranged on the movable part, and a fastening bolt is threadedly connected in the groove wall of the fixed groove.

[0023] By adopting the technical scheme, the push-moving part and the movable part are detachably connected together, when the reset spring is damaged, the fastening bolt only needs to be loosened, then the movable part is dismounted, the reset spring is compressed, and then the push-moving part is pushed out of the through hole, so that the reset spring can be taken out and replaced, and the operation is convenient. Compared with replacing the entire shoe sole mold, only the reset spring needs to be replaced, resources are saved, and the service life of the shoe sole mold is prolonged.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. When the mold is opened, the demolding mechanism can directly pop out the formed shoe sole from the first type groove, and only the shoe sole needs to be separated from the mold core, without the need to insert a tool into the first type groove to peel off the shoe sole, so that the operation is convenient and labor-saving, and the efficiency of demolding the shoe sole is improved.

[0026] 2. The guide column and the stop column can limit the deformation direction of the reset spring, so that the reset spring is not easy to deviate or swing, and the service life of the reset spring is prolonged.

[0027] 3. The mold core is detachably arranged on the push plate, different styles of mold core can be replaced, and the style of the formed shoe sole is flexible and changeable. BRIEF DESCRIPTION OF DRAWINGS
