[0021] See also Figure 1-4 , the utility model provides a technical solution:
[0022] A one-piece inner core mold for shoemaking comprises a bottom mold 1, a top mold 2, and an inner core 3. Shoe molds 4 are provided on both sides of the inner core 3. A bottom groove 401 is provided on the top surface of the bottom mold 1, and a top groove 402 is provided on the bottom surface of the top mold 2. The shoe mold 4 is gap-connected with the bottom groove 401 and the top groove 402.
[0023] By adopting the above design, the inner core 3 can be placed between the bottom mold 1 and the top mold 2, and the shoe mold 4 can be placed on both sides of the inner core 3. Then, the bottom mold 1 and the top mold 2 are merged, and the two sides of the shoe mold 4 can be plasticized through the bottom groove 401 and the top groove 402 thereon. Then, the bottom mold 1 and the top mold 2 are separated to complete the plasticization of the shoe mold 4.
[0024] Second protrusions 102 are provided on both sides of the top surface of the bottom mold 1, and second slots 202 adapted to the first protrusions 101 are provided on both sides of the bottom surface of the top mold 2. The second protrusions 102 and the second slots 202 correspond to each other in position.
[0025] By adopting the above design, after the bottom mold 1 and the top mold 2 are docked, the second protrusion 102 and the second slot 202 can be docked to complete the connection and fixation of the bottom mold 1 and the top mold 2, thereby preventing the bottom mold 1 and the top mold 2 from offsetting after being merged.
[0026] A first protrusion 101 is provided at the center of the top surface of the bottom mold 1 . There are two first protrusions 101 , which are spaced apart on the left and right central axes of the bottom mold 1 . A first slot 302 adapted to the first protrusion 101 is provided on the bottom surface of the inner core 3 .
[0027] By adopting the above design, after the bottom mold 1 and the top mold 2 are docked, the first protrusion 101 and the first slot 302 can be docked to complete the connection and fixation between the bottom mold 1 and the inner core 3, thereby preventing the inner core 3 from being offset relative to the bottom mold 1 after the bottom mold 1 and the top mold 2 are merged.
[0028] The bottom surface of the top mold 2 is provided with a third card slot 203 . There are two third card slots 203 , which are spaced apart on the left and right central axes of the top mold 2 . The top surface of the inner core 3 is provided with a third card block 303 adapted to the third card slot 203 .
[0029] By adopting the above design, after the bottom mold 1 and the top mold 2 are docked, the third card slot 203 and the third card block 303 can be docked to complete the connection and fixation of the top mold 2 and the inner core 3, thereby preventing the inner core 3 from being offset relative to the top mold 2 after the bottom mold 1 and the top mold 2 are merged.
[0030] The first protrusion 101 , the second protrusion 102 and the third clamping block 303 are in a truncated cone shape, and the first clamping slot 302 , the second clamping slot 202 and the third clamping slot 203 are truncated cone grooves adapted thereto respectively.
[0031] By adopting the above design, the larger entrance of the frustum groove can play a guiding role when merging, making it easier to clamp and align the bottom mold 1, the top mold 2 and the inner core 3. Moreover, after the frustum groove and the frustum protrusion are connected, the smaller area of the connecting end can also ensure the accuracy after the connection.
[0032] It also includes a hinge for connecting the bottom mold 1 and the top mold 2 and a demoulding assembly; the demoulding assembly includes a pressing block 301, which is arranged at the end of the inner core 3; a pressing groove 201, which is opened at the end of the top mold 2 and has a depth greater than the height of the pressing block 301. The pressing block 301 is a T-shaped protrusion, and the pressing groove 201 is a T-shaped groove adapted thereto.
[0033] By adopting the above design, when the mold is opened, the hinge can be used as an axis to rotate the other side of the top mold 2 upward to separate the bottom mold 1 and the top mold 2. At this time, the pressing groove 201 on the top mold 2 will press the pressing block 301, causing it to tilt up. Since the depth of the pressing groove 201 is greater than the height of the pressing block 301, there will be a certain angle difference between the top mold 2 and the inner core 3, so that the inner core 3 is located between the bottom mold 1 and the top mold 2 after tilting, allowing the staff to remove the shoe mold 4 from the inner core 3 more conveniently.
[0034] Working principle:
[0035] When opening the mold, the hinge can be used as an axis to rotate the other side of the top mold 2 upward to separate the bottom mold 1 and the top mold 2. At this time, the pressing groove 201 on the top mold 2 will press the pressing block 301, causing it to tilt up. Since the depth of the pressing groove 201 is greater than the height of the pressing block 301, there will be a certain angle difference between the top mold 2 and the inner core 3, so that the inner core 3 exists between the bottom mold 1 and the top mold 2 after tilting, allowing the staff to remove the shoe mold 4 from the inner core 3 more conveniently.
