Abstract
The invention discloses a lateral inclined-knockout core-loosening device arranged in a lateral sliding block. The technical scheme adopted by the invention is as follows: the device comprises a lateral sliding block (1), a ball pin (11), an inclined knockout rod (2), a back-off pellet (21), a locator (22), a stop dog (23), an inclined knockout base (3) and a restraining slot (31). The lateral inclined knockout core-loosening device arranged in the lateral sliding block is characterized in that the inclined knockout rod and the back-off pellet are arranged in the lateral sliding block; and during die sinking, the inclined knockout rod and the back-off pellet aslant slide to extend out of the lateral sliding block under the restriction of the stop dog while an inclined guide post drives the lateral sliding block to carry out lateral demoulding, so that the back-off pellet is laterally skew to loosen the core and demould in a back-off mode from a product along the direction orthogonal with the demoulding direction of the lateral sliding block, and therefore the problems and defects of complex structure, high cost, low efficiency and high possibility of generating wastes in the prior art are overcome. The inclined knockout mechanism is arranged in the lateral sliding block, so that the structure of the injection molding mould for laterally skewing to loosen the core and demould in a back-off mode for the product is simplified, the cost is lowered, the demoulding efficiency is improved, and wastes are avoided.
