Description

Sole blank forming die

Technical Field

The utility model relates to a sole mould field, concretely relates to sole stock forming die.

Background

The traditional sole forming method is characterized in that foaming raw materials are injected into a forming die, and the foaming raw materials are heated by the forming die to form the sole in a foaming mode in a die section. In order to overcome the defects, the applicant previously filed an invention patent application with the patent name of 'a high-elasticity composite material and an in-mold pore foaming forming process thereof' and the application number of 201910056079.2 to the national intellectual property office, wherein in the patent application, the applicant firstly uses a forming mold to form a sole blank and then puts the sole blank into a reaction kettle for foaming, and finally the foaming material can obtain excellent performances of large pores and good rebound resilience. However, in the long-term use process, the fact that when the sole blank is placed into the reaction kettle to be contacted with the inert gas, the inert gas and the composite material are required to be processed for 1-3 hours to be dissolved and mixed is found, the processing time is too long, the improvement of the sole production efficiency is not facilitated, therefore, if the sole blank structure can be improved to enable the sole blank structure to be rapidly reacted with the inert gas, the improvement of the sole production efficiency is facilitated, and a brand new sole blank forming mold needs to be developed if the sole blank structure is improved.

SUMMERY OF THE UTILITY MODEL

There is above-mentioned defect to prior art, the utility model aims to provide a sole stock forming die can make the sole stock that the shaping goes out mix the reaction with inert gas faster, and concrete technical scheme is as follows:

a sole blank forming die comprises an upper die plate and a lower die plate, wherein a sole forming bulge is arranged at the bottom of the upper die plate and provided with a plurality of cylinders which are arranged at equal intervals, a sole forming groove corresponding to the sole forming bulge is arranged on the lower die plate, a runner communicated with the sole forming groove is arranged on the surface of the lower die plate, and the upper die plate and the lower die plate are closed; the sole forming bulge is embedded into the sole forming groove to form a sole cavity, and the cylinder forms a sole air hole.

As an optimized proposal of the utility model, the surfaces of the upper template bottom surface and the lower template are coated with a Teflon layer.

As an optimized proposal of the utility model, the lower template is provided with an exhaust groove.

As an optimized proposal of the utility model, the sole forming bulge and the sole forming groove are respectively provided with 4.

The utility model has the advantages that: after cope match-plate pattern, lower bolster compound die, sole raw and other materials flow into the sole die cavity that the sole shaping is protruding to be formed with sole shaping recess through the flow channel direction in, the shaping goes out the sole stock, simultaneously because the sole shaping arch is equipped with the cylinder that a plurality of equidistance were arranged, the cylinder can make the sole stock shaping go out a plurality of sole gas pockets, inert gas gets into the gas pocket and reacts with the sole stock fast when being favorable to sequent secondary foaming, improves sole production efficiency.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

As shown in fig. 1 and 2, a sole blank forming mold comprises an upper mold plate 1 and a lower mold plate 2, wherein a sole forming protrusion 3 is arranged at the bottom of the upper mold plate 1, a plurality of cylinders 4 are arranged at equal intervals on the sole forming protrusion 3, a sole forming groove 5 corresponding to the sole forming protrusion 3 is arranged on the lower mold plate 2, a runner 6 communicated with the sole forming groove 5 is arranged on the surface of the lower mold plate 2, the number of the sole forming protrusion 3 and the number of the sole forming groove 5 are respectively 4, and when the upper mold plate 1 and the lower mold plate 2 are assembled; the sole forming bulge 3 is embedded into the sole forming groove 5 to form a sole cavity, and the column 4 forms a sole air hole in the sole blank.

Specifically, the surface coating of 1 bottom surface of cope match-plate pattern, 2 lower templates has the teflon layer and helps the better drawing of patterns of sole stock, and lower template 2 is equipped with air discharge duct 7, and air discharge duct 7 exhausts when being used for the shaping.

To sum up, the utility model discloses sole stock forming die's advantage lies in, behind cope match-plate pattern, the lower bolster compound die, in sole raw and other materials flowed into the sole die cavity that the sole shaping is protruding to be formed with sole shaping recess through the flow channel direction, the shaping goes out the sole stock, simultaneously because the protruding cylinder that is equipped with a plurality of equidistance and arranges of sole shaping, the cylinder can make the sole stock shaping go out a plurality of sole gas pockets, when being favorable to sequent secondary foaming inert gas gets into the gas pocket and reacts with the sole stock fast.
