Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, the sole mold structure includes an upper mold base 20 and a lower mold base 10, the middle of the lower mold base 10 has a mold cavity 110, the upper mold base 20 has a male mold 210 for forming the upper surface of the sole, a pouring hole 30 is opened on the side wall of the mold cavity facing the narrow side of the sole, pouring channels 310 capable of communicating with the pouring hole are provided on the opposite surfaces of the upper mold base and the lower mold base, a negative pressure hole 40 is opened on the side wall of the mold cavity facing the wide side of the sole, negative pressure channels 410 capable of communicating with the negative pressure hole are provided on the opposite surfaces of the upper mold base and the lower mold base, and the negative pressure channels are communicated with a negative.

The negative pressure holes 40 are arranged in a fan shape, the negative pressure channel 410 includes an arc-shaped communicating groove 411 arranged towards the mold cavity and communicated with each negative pressure hole, and a negative pressure straight-through groove 412 extending in the middle of the arc-shaped communicating groove, and the negative pressure straight-through groove is communicated with a negative pressure pump through a pipeline 413.

In this embodiment, the surface of the mold cavity has a raised pattern 111 for forming a bottom structure, the upper and lower mold bases have guide holes 103 around the sides for passing through guide posts when being fixed, the upper and lower mold bases have mutually matched positioning pins 101 and positioning holes 102, the positioning pins 101 and the positioning holes 102 are used for the mold cavity to have a pair, the casting channels of the mold cavities are symmetrically arranged, and the casting channel 310 and the negative pressure channel 410 are arranged in a V shape.

In this embodiment, the negative pressure hole is located on the lower die holder and the lower die holder is located the die cavity and has the boss towards sole broadside one end, negative pressure hole outside-in slant from high to low setting, thereby the design of boss 104 is the slant processing that conveniently is located the inside negative pressure hole of lower die holder for the thickness increase of the position lower die holder at messenger's negative pressure hole place, adopts the slant transition can improve the unobstructed vacuum effect that reaches fast inside the messenger die cavity of negative pressure air current.
