Description

Technical Field

[0001] The utility model relates to the technical field of sole molds, in particular to a multi-layer sole forming mold. Background Art

[0002] In the prior art, a multi-layer sole mold generally includes a fixed mold, and then a plurality of movable molds are arranged to cooperate with the fixed mold; for example, Chinese Patent Publication No. CN218477021U discloses an EVA multi-color sole foaming and forming mold. By turning the third mold base onto the first mold base, the second boss extends into the first forming groove, and the second boss and the first forming groove form a first mold cavity. EVA material is filled into the first mold cavity for foaming and forming to make the first layer of the sole. Then, the third mold base is reset, and the second mold base is turned onto the first mold base, so that the first boss extends into the first forming groove. The first boss, the first forming groove and the first layer of the sole form a second mold cavity. EVA material is filled into the second mold cavity for foaming and forming to make a double-layer multi-color sole. However, the turning of the second mold base and the third mold base needs to be manually turned to be combined with the first mold base. Since the temperature of the mold is relatively high during production, when manually turning the mold, it is difficult for workers to operate and the efficiency is relatively low.

[0018] The following specific implementation content provides multiple different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures being discussed.

[0019] The following description with reference to the drawings and specific implementation manners further describes the present utility model: As Figures 1 - 4 shown, a multi-layer sole molding mold includes a fixed mold 1, a first moving mold 2, and a second moving mold 3. The first moving mold 2 is hinged to the left side of the fixed mold 1 for left-right flipping, and the second moving mold 3 is hinged to the right side of the fixed mold 1 for left-right flipping. A flipping power mechanism is installed on the front side of the fixed mold 1, and the flipping power mechanism is used to drive the first moving mold 2 and the second moving mold 3 to flip simultaneously, and to make the first moving mold 2 and the second moving mold 3 alternately perform closing or opening actions with the fixed mold 1.

[0020] In the present utility model, a flipping power mechanism is installed on the fixed mold 1. Through the flipping power mechanism, the first moving mold 2 and the second moving mold 3 can be driven to flip simultaneously, and the first moving mold 2 and the second moving mold 3 alternately perform closing or opening actions with the fixed mold 1. That is, when the first moving mold 2 is closed with the fixed mold 1, the second moving mold 3 is in an open state. Then, raw materials are injected into the feeding port of the first moving mold 2 to form the first layer of the sole. Then, when the first moving mold 2 is opened, the second moving mold 3 flips towards the fixed mold 1 for closing, realizing the alternately closing or opening actions of the first moving mold 2 and the second moving mold 3 with the fixed mold 1.

[0021] Thus, there is no need for manual flipping of the first moving mold 2 and the second moving mold 3 by workers, reducing the labor intensity of workers and improving production efficiency at the same time.

[0022] Furthermore, hinge seats 21 are provided on both the left and right sides of the fixed mold 1. Extension blocks 22 are provided on one side of the first moving mold 2 and the second moving mold 3. A flipping shaft 23 is provided on the extension block 22, and the flipping shaft 23 is correspondingly rotatably disposed on the hinge seat 21.

[0023] See Figures 1 - 4As shown in the figure, the flipping power mechanism includes a connecting seat 31 provided on the front side of the fixed mold 1. A supporting cross plate 32 is arranged on the connecting seat 31. A motor mounting seat 33 is arranged on the outer side of the supporting cross plate 32. A motor 34 is arranged on the motor mounting seat 33. A rack 35 slides left and right on the inner side of the supporting cross plate 32. The output shaft of the motor 34 passes through the supporting cross plate 32 and is connected with a driving gear 36 that can mesh with the rack 35. Transmission gears 37 that can mesh with the rack 35 are also installed at left and right intervals on the inner side of the supporting cross plate 32. The left and right flipping shafts 23 are correspondingly arranged with the transmission gears 37 on both sides, and a connecting component for coaxially connecting the two is connected between the corresponding flipping shaft 23 and the transmission gear 37.

[0024] During operation, the motor 34 drives the driving gear 36 to rotate and mesh with the rack 35. The rack 35 moves and meshes with the transmission gears 37 on both the left and right sides, thereby driving the left and right flipping shafts 23 to rotate in the same direction, realizing the clamping or mold opening actions of the first moving mold 2 and the second moving mold 3 alternately with the fixed mold 1 in sequence.

[0025] Further, the connecting component includes a first connecting column 41 provided at the front end of the flipping shaft 23. A second connecting column 42 is arranged at one end of the transmission gear 37 close to the flipping shaft 23. A clamping groove 43 is arranged at the end of the first connecting column 41. A clamping block 44 that can be clamped into the clamping groove 43 is arranged at the end of the second connecting column 42.

[0026] The connecting seat 31 is detachably connected to the supporting cross plate 32. The connecting seat 31 includes a lower seat 51 and an upper seat 52. Threaded holes 53 are spaced at the upper end of the lower seat 51. Through holes 54 corresponding to the threaded holes 53 are spaced on the upper seat 52. Bolts 55 that can be threadedly connected with the threaded holes 53 are arranged in the through holes 54.

[0027] Blocking blocks 61 are arranged on the left and right sides of the lower seat 51. The upper seat 52 is arranged between the two blocking blocks 61.

[0028] During installation, the upper seat 52 is placed between the two blocking blocks 61, and then the bolts 55 pass through the through holes 54 of the upper seat 52 and are threadedly connected with the threaded holes 53 of the lower seat 51 to fix the upper seat 52 and the lower seat 51. At the same time, the clamping block 44 at the end of the second connecting column 42 can be clamped into the clamping groove 43 of the first connecting column 41, so that the rotation of the transmission gear 37 can drive the flipping shaft 23 to rotate.

[0029] Further, a T-shaped sliding groove is arranged along the left and right directions on the inner side of the supporting cross plate 32. A T-shaped sliding block is arranged on one side of the rack 35. The T-shaped sliding block slides in the T-shaped sliding groove, enabling the rack 35 to slide smoothly.

[0030] In the present utility model, cushion blocks 81 are provided on the outer end faces of the first moving die 2 and the second moving die 3. When the first moving die 2 or the second moving die 3 is in the open die state, the outer end faces of the cushion blocks 81 are on the same horizontal plane as the bottom surface of the fixed die 1. Thus, the cushion blocks 81 can abut against the workbench, support the first moving die 2 or the second moving die 3, and at the same time enable the first moving die 2 or the second moving die 3 to better fit on the fixed die 1.
