The utility model relates to a shoe mold matching structure, which comprises an upper mold and a lower mold; the upper die is characterized in that a shoe die annular wall is arranged on the top surface of the lower die, a forming groove is formed in the shoe die annular wall, a forming protrusion is formed in the bottom surface of the upper die, an annular groove surrounding the edge of the forming protrusion is formed in the bottom surface of the upper die, when the lower die and the upper die execute die closing operation, the shoe die annular wall of the lower die is embedded in the annular groove, the forming protrusion is embedded in the forming groove, and a space for forming the shoe die is reserved between the bottom of the forming protrusion and the bottom of the forming groove. When the upper die and the lower die execute die assembly operation, the annular groove of the upper die can be embedded with the top of the annular wall of the shoe die of the lower die, so that the air tightness of the die assembly operation can be ensured, and the production quality of the shoe die is further ensured.

Description

Shoe mold matching structure

Technical Field

The utility model relates to the technical field of shoe molds, in particular to a shoe mold matching structure.

Background

The shoe mold generally comprises an upper mold and a lower mold, wherein a molding groove is formed in the mold clamping surface of one mold, a molding protrusion is formed in the mold clamping surface of the other mold, a space for molding the shoe mold exists between the molding protrusion and the molding groove, raw materials are injected into the molding groove and then subjected to mold clamping operation, the mold clamping protrusion is embedded into the molding groove in the mold clamping process, a shoe mold is generated under certain temperature, pressure and other conditions, however, the side walls of the molding protrusion and the molding groove cannot be completely attached to each other in the mold clamping process, certain gaps exist, so that the sealing performance in the mold clamping process is poor, and the molding effect of the shoe mold is affected.

Disclosure of Invention

First, the technical problem to be solved

In order to solve the problems in the prior art, the utility model provides a shoe mold matching structure which can save raw materials.

(II) technical scheme

In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: a shoe mold matching structure comprises an upper mold and a lower mold;

the upper die is characterized in that a shoe die annular wall is arranged on the top surface of the lower die, a forming groove is formed in the shoe die annular wall, a forming protrusion is formed in the bottom surface of the upper die, an annular groove surrounding the edge of the forming protrusion is formed in the bottom surface of the upper die, when the lower die and the upper die execute die closing operation, the shoe die annular wall of the lower die is embedded in the annular groove, the forming protrusion is embedded in the forming groove, and a space for forming the shoe die is reserved between the bottom of the forming protrusion and the bottom of the forming groove.

Further, the bottom surface of the forming groove is in an inclined plane shape, and the top surface of the forming protrusion is parallel to the bottom surface of the forming groove.

Further, a plurality of first mounting through holes are formed in the outer edge of the upper die at intervals, and a plurality of second mounting through holes are formed in the outer edge of the lower die at intervals.

Further, the top of the shoe mold ring wall is provided with an outwardly extending edge.

(III) beneficial effects

The beneficial effects of the utility model are as follows: when the upper die and the lower die execute die assembly operation, the annular groove of the upper die can be embedded with the top of the annular wall of the shoe die of the lower die, so that the air tightness of the die assembly operation can be ensured, and the production quality of the shoe die is further ensured.

Drawings

FIG. 1 is an exploded view of a shoe mold mating structure of the present utility model;

FIG. 2 is a longitudinal cross-sectional view of the present utility model;

[ reference numerals description ]

1. A lower die; 2. an upper die; 3. a shoe mold annular wall; 4. an edge; 5. forming a bulge; 6. a ring groove; 7. a first mounting through hole; 8. a second mounting through hole; 9. and forming grooves.

Detailed Description

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings.

Example 1

Referring to fig. 1 to 2, a shoe mold matching structure includes an upper mold 2 and a lower mold 1;

the top surface of lower mould 1 is equipped with shoes mould rampart 3, be equipped with shaping recess 9 in the shoes mould rampart 3, the bottom surface of last mould 2 is equipped with shaping arch 5, the bottom surface of last mould 2 is equipped with around shaping arch 5 border 4's annular 6, works as lower mould 1 with go up mould 2 and carry out the compound die operation, shoes mould rampart 3 of lower mould 1 is inlayed and is located in annular 6, shaping arch 5 is inlayed and is located in the shaping recess 9, leave the space that is used for shoes mould shaping between the bottom of shaping arch 5 with the bottom of shaping recess 9.

In this embodiment, the bottom surface of the molding groove 9 is inclined, and the top surface of the molding protrusion 5 is parallel to the bottom surface of the molding groove 9, so that the molding area of the sole model can be increased in the molding groove 9 with a certain size.

In this embodiment, a plurality of first mounting through holes 7 are formed in the outer edge of the upper die 2 at intervals, and a plurality of second mounting through holes 8 are formed in the outer edge of the lower die 1 at intervals, so that the upper die 2 and the lower die 1 can be conveniently mounted and fixed in a fixing manner such as a nut.

In this embodiment, the top of the shoe mold annular wall 3 is provided with an edge 4 extending outwards, so that the width of the top of the shoe mold annular wall 3 can be increased under the condition that the thickness of the shoe mold annular wall 3 is smaller, and the air tightness in the mold closing process is improved.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent changes made by the specification and drawings of the present utility model, or direct or indirect application in the relevant art, are included in the scope of the present utility model.
