Description
Technical Field
The utility model relates to a manufacturing equipment for ball mill rubber lining, in particular to a lifting strip injection molding die.
Background
At present, the production ball mill rubber lining's of domestic and abroad promotion strip product all adopts forming die compression molding, as shown in figure 1, forming die includes lower bolster 1, cope match-plate pattern 2, mold core 3, when taking out the promotion strip 4 that will suppress from the mould, mainly rely on artifical with the crow bar to utilize the elastic deformation of rubber to force the promotion strip 4 from mold core 3 and take out, not only production efficiency is lower, and intensity of labour is big, it requires high to operator's health quality, because it is restricted by post recruitment, be unfavorable for sustainable development.
Disclosure of Invention
Problem to above-mentioned prior art exists, the utility model provides a lifting strip injection moulding mould can realize the automatic drawing of patterns of product, improves production efficiency, reduces working strength.
The utility model adopts the technical scheme as follows: promote strip injection moulding mould, including lower bolster, cope match-plate pattern, mold core, roof, the lower bolster middle part is provided with ascending boss, the mold core sets up on the boss the bottom surface of lower bolster is provided with the recess, the mold core lower part runs through the boss and extends to in the recess, at mold core lower part fixedly connected with locating piece, the locating piece size with the recess matches, the roof is located the both sides of boss and paste tight boss side, the lower part of cope match-plate pattern is equipped with open die cavity, is equipped with the notes gluey hole of intercommunication die cavity on cope match-plate pattern upper portion.
Furthermore, one side of the top plate, which is close to the boss, is an inclined surface, and the boss is provided with an inclined surface matched with the top plate.
Furthermore, the upper template consists of a cover plate and a middle template, the mold cavity is enclosed by the cover plate and the middle template, and the glue injection hole is formed in the cover plate.
The beneficial effects of the utility model reside in that: adopt the utility model discloses a lifting strip injection moulding mould can realize that the lifting strip after the shaping is automatic to be deviate from, realizes automated production, has solved the problem that lifting strip is difficult to the drawing of patterns among the prior art, simultaneously, utilizes large capacity injection machine injection moulding, and production efficiency improves more than 30%.

Detailed Description
To facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the specific embodiments described below.
As shown in fig. 2-3, the injection molding mold for the lifting bar of this embodiment includes a lower mold plate 1, an upper mold plate 2, a mold core 3, and a top plate 5, an upward boss 101 is provided in the middle of the lower mold plate 1, the mold core 3 is provided on the boss 101, a groove 6 is provided on the bottom surface of the lower mold plate, the lower portion of the mold core 3 penetrates through the boss 101 and extends into the groove 6, a positioning block 7 is fixedly connected to the lower portion of the mold core 3, the positioning block 7 is matched with the groove 6 in size, the top plate 5 is located on both sides of the boss 101 and tightly contacts the side surface of the boss 101, one side of the top plate 5 close to the boss 101 is an inclined surface, an inclined surface matched with the top plate 5 is provided on the boss 101, the upper mold plate 2 is composed of a cover plate 201 and a middle mold plate 202, the cover plate 201 and the middle mold plate 202 enclose a mold cavity 8 with an open lower portion, and a glue injection hole 9 communicated with the mold cavity is provided on the upper portion of the cover plate 201.
The utility model discloses a promotion strip injection moulding mould, the sizing material is injected into by the notes gluey hole 9 on cope match-plate pattern 2 upper portion, after the vulcanization is accomplished, take off cope match-plate pattern 2 earlier on the injection machine, fashioned promotion strip 4 is hung because of supporting mold core 3 on the lower bolster 1, still remain on the assembly of roof 5 and lower bolster 1, the back is thrown off completely to cope match-plate pattern 2, the roof 5, the lower bolster 1 is released the injection host computer together with product promotion strip 4, again with roof 5 push-up, product promotion strip 4 and mold core 3 are along with roof 5 upwards move the certain distance after together, no longer continue going upward because of mold core 3 is restricted by locating piece 7, roof 5 continues to rise again promotes strip 4 with the product and holds in the palm, reach product complete demoulding effect.
The utility model discloses the key lies in that roof 5 rises and holds up mold core 3 simultaneously, makes the product part that is located the position under mold core 3 break away from lower bolster 1, and when roof 5 continued to rise and held in the palm out the product, utilizes rubber component's elasticity, can not produce the product when forcing to hold in the palm out the product and destroy. After the product is completely removed from the mold, the operator only needs to take back the product from the top plate 5 of the mold.
Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
