Description

A kind of foaming footwear mould of making sole

Technical field

The present invention relates to shoe-making die, specifically refer to a kind of foaming footwear mould of making sole.

Background technology

Existing air blowing footwear mould generally comprises upper die and lower die and core rod, this upper and lower mould is respectively equipped with corresponding upper and lower die cavity, described core rod is arranged in the space of described upper and lower die cavity formation, and the left and right sidewall of upper and lower die cavity forms the moulding of corresponding left and right sole bottom surface, be positioned at its side-walls in this upper cavity and be provided with the last prick post of a row that is intervally arranged, be positioned at its side-walls in this lower mode cavity and be provided with prick post under the row who cooperates with the last prick post of a row, described patrix is provided with shoot material passage and inlet channel, and described counterdie is provided with outlet passageway.

Its air blowing injection moulding process is, foamed materials such as PVC are entered in the upper and lower die cavity by the passage that shoots material of patrix, and gases at high pressure are entered by inlet channel, the operation of in upper and lower die cavity, foaming of foamed materials such as PVC, after foaming operation a period of time, open patrix, take out sole and namely finish.This air blowing injection moulding mode can be produced foaming product.

Above-mentioned air blowing injection moulding mode can come with some shortcomings, because left and right sole is the mode injection moulding that is formed corresponding left and right sole bottom surface by the left and right sidewall of upper and lower die cavity, like this in the foaming operation process, hold sealing part between the upper and lower die cavity and can extrude a raised line line, after opening loam cake, this raised line line is positioned at sole bottom surface center, have a strong impact on the performance of the sole integral body that foams out, and this raised line line is the unnecessary part that goes out, subsequent technique also will scabble it, and whole operation is made the cost height; Adopt the design of upper and lower prick post, along with opening of patrix, last prick post breaks away from sole, takes out sole, namely its sole bottom of making along the horizontal row on its length direction to perforation.But because the length of upper and lower prick post is subjected to the restriction of mold integral design, the height sum of its upper and lower prick post forms the height in space less than upper and lower die cavity, each horizontal perforation disconnects like this, the perforation of the horizontal penetration type of a whole piece be can not form, its sole integral, flexible and easy bending performance influenced.

Summary of the invention

The invention provides a kind of foaming footwear mould of making sole, it is undesirable that its main purpose is to overcome existing air blowing footwear mode structure design, the sole center of making the raised line line can occur and perforation that each is horizontal is to disconnect, and has a strong impact on the shortcoming of the whole various aspects of performance of sole.

For solving the problems of the technologies described above, the present invention adopts following technical scheme:

A kind of foaming footwear mould of making sole, comprise core rod, have the patrix of upper cavity and the counterdie that cooperates and have lower mode cavity with patrix, also comprise the exhaust outlet of discharging for gas in the upper and lower die cavity, described patrix is provided with shoot material passage and inlet channel, described lower mode cavity left and right side is respectively equipped with the left and right projection that is used to form the bottom surface moulding of whole sole, described core rod is assemblied in the middle part of upper cavity, and the corresponding left and right groove that cooperates with left and right projection that forms in this core rod left and right sides.

Be equipped with the row's prick post that is used to form the perforation that the sole bottom transverse runs through in the described left and right groove, and this two rows prick post is corresponding to core rod one side; Be provided with two plug sockets that cooperate with two row's prick posts in the described lower mode cavity, and two plug sockets are near the corresponding side of left and right projection.

Described core rod is locked in the middle part of upper cavity by locking part, and the middle part of described lower mode cavity offers the adaptive groove adaptive with the head of locking part.

Each row's prick post is the triangular column, and the socket of each socket is the triangle socket.

Each row's prick post is cylindric, and the socket of each socket is the circle socket.

By above-mentioned description to structure of the present invention as can be known, compare with prior art, the present invention has following advantage: this air blowing footwear mode structure new meaning, the left and right sole of making does not all have the raised line line, improved the performance of the sole integral body that foams out greatly, and need not subsequent technique that left and right sole bottom surface is scabbled, reduced cost of manufacture.Because left and right whole sole bottom surface moulding forms at the left and right projection of correspondence respectively, after opening patrix, takes out left and right sole, this left and right sole bottom surface can not generate the raised line line, has guaranteed the quality of the left and right sole after the foaming.Adopt the design that cooperates between prick post and the socket, along with opening of patrix, extract prick post from socket after, the sole bottom is along forming a horizontal row to the perforation that runs through on its length direction, this perforation is penetration type, has improved sole integral, flexible and easy bending performance greatly.

The specific embodiment

The specific embodiment of the present invention is described with reference to the accompanying drawings.

With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.A kind of foaming footwear mould of making sole comprises core rod 1, has the patrix 2 of upper cavity and cooperates and have the counterdie 3 of lower mode cavity with patrix 2, also comprises the exhaust outlet (figure does not mark) of discharging for gas in the upper and lower die cavity.Described patrix 2 is provided with shoot material passage 21 and inlet channel 22.Described lower mode cavity left and right side is respectively equipped with the left and

right projection

31,32 that is used to form the bottom surface moulding of whole sole.Described core rod 1 is assemblied in the middle part of upper cavity, and the corresponding left and
