Quick-change shoe mold structure

Abstract

This invention provides a quick-changeable shoe mold structure, comprising: a mold frame structure having a top support portion and a bottom support portion, with an accommodating space between the top support portion and the bottom support portion, and at least one connecting portion between the top support portion and the bottom support portion; the top support portion having a notch, with locking structures on opposite sides of the notch; a bottom mold structure disposed on the bottom support portion; and a last structure having a connecting hanging portion and a body portion, the hanging portion being positioned at the notch, the body portion extending into the accommodating space, and an injection hole penetrating the hanging portion and the body portion, with corresponding structures on opposite sides of the hanging portion, the corresponding structures being positioned by the locking structures.

Claims

1. A quick-change shoe mold structure, comprising: A mold frame structure has a top support portion and a bottom support portion, with an accommodating space between the top support portion and the bottom support portion, and at least one side connecting portion between the top support portion and the bottom support portion. The top support portion has a notch, and each of the two opposite sides of the notch has a locking structure. A bottom mold structure is disposed on the bottom support portion. A last structure has a hanging portion and a body portion connected together. The hanging portion is positioned at the notch, and the body portion extends into the accommodating space. It also has at least one injection hole that penetrates the hanging portion and the body portion. Each of the two opposite sides of the hanging portion has a corresponding structure, and the corresponding structure is positioned by the locking structure.

2. The quick-change shoe mold structure as described in claim 1, wherein, There are two connecting parts on this side.

3. The quick-change shoe mold structure as described in claim 1, wherein, The bottom mold structure has a top surface and a bottom surface, which are opposite to each other. The bottom surface is used to abut against the bottom support portion, and the top surface is used to support a piece.

4. The quick-change shoe mold structure as described in claim 1, wherein, The locking structure is a stepped structure, and there are two locking structures. The two locking structures are located on the top support part and on opposite sides of the notch. Each locking structure has a protruding part and a recessed part. The protruding part is closer to the accommodating space than the recessed part. There is a first distance between the protruding parts and a second distance between the recessed parts. The first distance is smaller than the second distance. The side of the protruding part facing away from the accommodating space is a support surface. The corresponding structure is an inverted stepped structure. Each of the two corresponding structures has an outward protrusion and an inner step. The inner step is closer to the main body part than the outward protrusion. The outward protrusion is located between the two recessed parts, and the inner step is located between the two protruding parts. Each outward protrusion has a lower side surface that faces the main body part and abuts against the support surface.
