Detailed Description

In order to better understand the technical solutions, the technical solutions will be described in detail with reference to the description and the specific embodiments.

In a specific embodiment, as shown in fig. 1 and 2, the tpu sole mold of the present application is used for manufacturing a tpu sole, the tpu sole comprises a first component 1, the first component 1 comprises an upper backing plate 101, a female mold 102 fixedly connected with the upper backing plate 101, and one end of a pull rod 103 penetrating through the female mold 102 and connected with the upper backing plate 101, and a mold core is movably installed at the other end of the pull rod 103; the device also comprises a second component 2, wherein the second component 2 comprises a lower backing plate 21; a male die 22 fixedly connected with the lower backing plate 21;

wherein, as shown in fig. 1, when the tpu sole mold is in the first state, the first component 1 is away from the second component 2; as shown in fig. 2, when the tpu sole mold is in the second state, i.e. the tpu mold is in the closed state, the female mold 102 is engaged with the male mold 22, and the core is located between the female mold 102 and the male mold 22, and forms a cavity 111.

Specifically, the mold core comprises a first inner core 104, a first shoe mold inner core 107 and a second shoe mold inner core 108, the first shoe mold inner core 107 and the second shoe mold inner core 108 are respectively positioned at two sides of the first inner core 104, and the first inner core 104, the first shoe mold inner core 107 and the second shoe mold inner core 108 can be integrally formed or assembled after being separately injection molded.

Taking the assembled mold core as an example, the first shoe mold inner core 107 and the second shoe mold inner core 108 can be respectively installed on two sides of the first inner core 104 through the first bolt 105, the shapes of the first shoe mold inner core 107 and the second shoe mold inner core 108 can be the same or different, when the shapes of the first shoe mold inner core and the second shoe mold inner core are the same, the produced soles are left feet or right feet, when the shapes of the first shoe mold inner core and the second shoe mold inner core are symmetrical, one produced sole is a left foot and one produced is a right foot, and no matter what combination mode, the tpu sole mold of the application can produce two soles at one time.

In other embodiments, the two bolts are respectively sleeved with the second spring 106, when the tpu sole mold is converted from the second state to the first state, that is, when the tpu sole mold is separated from the closed state, the second spring 106 can automatically eject the first shoe mold inner core 107 and the second shoe mold inner core 108 by 2-5mm respectively, so that the injection molded sole can be taken out conveniently.
