Abstract
The utility model discloses a rubber product producing mold, which comprises an upper mold and a lower mold. Two adjacent single cavities on the lower mold share a torn edge groove, the upper mold or the lower mold is further provided with a forming rubber fixing pin, correspondingly, the lower mold or the upper mold is provided with a matching hole, the upper mold or the lower mold is further provided with an excess material groove, the section of the shared torn edge groove is in the shape of a semi-ellipse, the major semi-axis of the semi-ellipse is located on a joint face, the shared torn edge groove extends to the edge of the lower mold, and the excess material groove is communicated with the shared torn edge groove. The rubber product producing mold is mainly used for producing rubber products, is particularly suitable for producing strip-shaped rubber products, resolves the problems that an existing strip-shaped rubber product producing mold is low in production efficiency and rubber utilization rate, and has the advantages of high production efficiency and rubber utilization rate.
Description
Technical field
The utility model relates to mould, particularly the rubber production mould.
Background technology
Tradition is when design strip rubber production mould, and it is independently that die cavity distributes, and each monomer die cavity all has oneself torn edges groove and clout groove, and the spacing between the two monomer die cavities is bigger, so just causes on the template of same size arranging of monomer die cavity just to be lacked.Simultaneously, material loading, the demoulding all are that die cavity comes in turn during production, and moulding sizing material one-tenth is block, arbitrarily puts during material loading, and efficient is very low, and the sizing material utilization rate is also very low.
Along with the development of torn edges rubber mold, also increasingly high to the designing requirement of torn edges groove, the torn edges groove all is to be designed to trapezoidally or semicircle usually, and trapezoidal torn edges groove needs hand wear into the processing of shape cutter, and the size of cutter cannot say for sure card, and is also not wear-resisting; Though semicircle torn edges groove is easy to process but the mould material removal is more, causes torn edges groove intensity to reduce greatly.
The utility model content
The purpose of the utility model provides a kind of rubber production mould, and existing strip rubber production mould production efficiency is low, the sizing material utilization rate is low and the problem of torn edges groove unreasonable structure to solve.
The purpose of the utility model realizes through following technical scheme:
A kind of rubber production mould comprises upper die and lower die, a public torn edges groove between two adjacent monomer die cavities on the said counterdie.
Also be provided with moulding sizing material steady pin on said patrix or the counterdie, correspondingly, said counterdie or patrix are provided with mating holes.
Also be provided with the clout groove on said patrix or the counterdie.
The cross section of said public torn edges groove is that major semiaxis is positioned at the half elliptic on the die joint.
Said public torn edges groove extends to said counterdie edge.
Said clout groove communicates with said public torn edges groove.
The beneficial effect of the utility model is: through public torn edges groove and clout groove, make the more monomer die cavity of can arranging on the template of same size, thereby enhance productivity and the sizing material utilization rate.

Among the figure: 1, patrix; 2, counterdie; 3, monomer die cavity; 4, torn edges groove; 5, steady pin; 6, clout groove; 7, brute spring; 8, lift ear.
The specific embodiment
Shown in Fig. 1-7, the rubber production mould of the utility model comprises patrix 1 and counterdie 2,3 public torn edges grooves 4 of two adjacent monomer die cavities on the said counterdie 2.The benefit of doing like this is: the more monomer die cavity of can arranging on the template of same size, thus enhance productivity and the sizing material utilization rate.
Also be provided with moulding sizing material steady pin 5 on said patrix 1 or the counterdie 2.Curl under the shaping sizing material nature, wayward when putting, steady pin has been arranged after, can the shaping sizing material is fixing well, like this, the distribution meeting of sizing material is more even in forming process.Correspondingly, said counterdie 2 or patrix 1 are provided with mating holes.
For holding sizing material unnecessary in the forming process, obtain the product of better quality, also be provided with clout groove 6 on said patrix 1 or the counterdie 2.
For ease of processing and proof strength, the cross section of said torn edges groove 4 is that major semiaxis is positioned at the half elliptic on the die joint.
For ease of taking out the rubber of moulding, said public torn edges groove 4 extends to said counterdie 2 edges.
For unnecessary sizing material can be drained fast, said clout groove 6 communicates with said public torn edges groove 4.
Brute spring 7 also is installed on the said patrix 1 and lifts ear 8.
The utility model is through public torn edges groove, clout groove, makes the more monomer die cavity of can arranging on the template of same size, and each monomer after the moulding links together, and is convenient to the demoulding, thereby improved production efficiency and sizing material utilization rate.
The utility model is mainly used in the production of rubber, is particularly suitable for the production of strip rubber, has the high and high advantage of sizing material utilization rate of production efficiency.
