Abstract
The utility model relates to the technical field of moulds and in particular relates to a long-life high-precision mould cavity product-forming position. Compared with the prior art, the long-life high-precision mould cavity product-forming position comprises a cavity product-forming position hole and a mould joint at which the mould cavity product-forming position hole lies, wherein the mould joint is extended by 7mm-15mm at the mould cavity product-forming position hole to form a concave surface at the edge of the mould cavity product-forming position hole; a concave distance between the concave surface and the mould joint is 0.2mm-0.3mm; and the mould cavity product-forming position is extended by 7mm-15mm to form the concave surface at the lower edge of the mould cavity product-forming position, so that the outer clearance of the mould cavity product-forming position is formed. The contact area of the mould joint can be reduced by the concave surface, so that mould locking force on the mould joint can be effectively reduced, and the service life of the mould is prolonged; meanwhile, the probability that the slag is left on the mould joint is reduced, the mould joint is kept clean, the mould cavity product-forming position can be used for conveniently exhausting gas, and the long-life and high-precision performances of the mould are ensured.
Description
Technical field
The present invention relates to technical field of mold, particularly a kind of long-life high-precision mold die cavity glue position.
Background technology
The cooperation place of separating at upper mould and counterdie is die joint, the open and close of die cavity all embody at die joint, owing to be the place of formed product in the glue position of die cavity, therefore in the formed product process, at die joint a clamp force is arranged, if the contact area between upper mould and the counterdie is big, this clamp force is just big, simultaneously also can cause other unfavorable factor, as after contacting greatly, somatotype is easy to generate residual material slag, and excessive contact-making surface also is unfavorable for the exhaust of glue position, as long-term use, can influence life-span and the precision of mould.
Summary of the invention
For solving the existing defective in die cavity glue position and problem in the prior art, provide a kind of long-life high-precision mold die cavity glue position.
The technical scheme that the present invention adopts for its technical problem of solution is: long-life high-precision mold die cavity glue position of the present invention comprises the die joint at hole, die cavity glue position and place, hole, die cavity glue position, described die joint is a concave surface at extension 7～15mm place, hole, die cavity glue position to bore edges place, die cavity glue position
Recessed distance between described concave surface and the die joint is 0.2～0.3mm.
The invention has the beneficial effects as follows: compared with prior art, long-life high-precision mold die cavity glue position of the present invention is by arranging a concave surface at extension 7～15mm place, hole, die cavity glue position to bore edges place, die cavity glue position, thereby form the outer empty avoiding of a die cavity glue position, can reduce the die joint contact area by concave surface, can effectively reduce the clamp force on the die joint, improve die life, also reduce simultaneously the probability of the residual material slag of die joint, keep die joint clean and tidy, make things convenient for the position exhaust of die cavity glue, guaranteed long-life and the high-precision performance of mould.
Description of drawings
Below in conjunction with the drawings and specific embodiments long-life high-precision mold die cavity glue position of the present invention is described further.
Fig. 1 is the perspective view of long-life high-precision mold die cavity glue position of the present invention.
The specific embodiment
As shown in Figure 1, long-life high-precision mold die cavity glue position of the present invention comprises the die joint 2 at hole, die cavity glue position 1 and 1 place, hole, die cavity glue position, die joint 2 is a concave surface 3 in hole, die cavity glue position 1 extension, 7～15mm place to hole, die cavity glue position 1 edge, recessed distance between concave surface 3 and the die joint 2 is 0.2～0.3mm, thereby form the outer empty avoiding in hole, a die cavity glue position 1, the hem width of concave surface 3 is adjusted according to mould size and die cavity projected area size.By the structure of this concave surface 3 is set, can reduce die joint 2 contacts area by concave surface 3, can effectively reduce the clamp force on the die joint 2, improve die life, also reduce simultaneously the probability of die joint 2 residual material slags, keep die joint 2 clean and tidy, make things convenient for 1 exhaust of hole, die cavity glue position, guaranteed long-life and the high-precision performance of mould.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
