Meanwhile, the first slider 71 drives the first transmission rod 61 to perform demolding movement through the first connecting rod 671, so that the first transmission rod 61 drives the guide block B521 to move along the sliding guide part B61, and the oblique-movement core-pulling B52 performs core pulling; the second slider 72 drives the second transmission rod 62 to perform demolding movement through the second connecting rod 672, so that the second transmission rod 62 drives the guide block A521 to move along the sliding guide part A62, and the inclined core pulling A52 performs core pulling. And ejecting the injection molding part by the ejector pin after all the loose cores are separated from the injection molding part, and completing demolding.
Referring to fig. 9-10, during mold closing, the first slider 71 and the second slider 72 are driven by the first inclined guide post 81 and the second inclined guide post 82 to perform a reset motion toward the center direction of the mold, so as to reset the translation core-pulling a51 and the translation core-pulling B51. Meanwhile, the first slider 71 drives the first transmission rod 61 to perform reverse reset motion through the first connecting rod 671, so that the first transmission rod 61 drives the guide block B521 to move along the sliding guide part B61, and the oblique core pulling B52 is reset; the second slider 72 drives the second transmission rod 62 to perform reverse reset motion through the second connecting rod 672, so that the second transmission rod 62 drives the guide block A521 to move along the sliding guide part A62, and the inclined core pulling A52 is reset. Until the movable die and the fixed die of the die are completely closed, the locking module 9 tightly locks the first sliding block 71 and the second sliding block 72. The mold is reset and waits for the next injection cycle to begin.
In the invention, a first transmission rod and a second transmission rod of a forming die of a 45-degree bent pipe piece are respectively and fixedly connected with a first sliding block and a second sliding block, so that the first sliding block and the second sliding block drive a translation core pulling A and a translation core pulling B to pull cores under the driving of a first inclined guide pillar and a second inclined guide pillar, and simultaneously drive the first transmission rod and the second transmission rod to enable the inclined core pulling A and the inclined core pulling B to pull cores.
