Detailed Description
In an embodiment, as shown in fig. 1 to 5, an injection mold with an adjustable core pulling extension distance includes a cavity 100 enclosed by a female mold 11 and a male mold 12, a core pulling mechanism 2 and a telescopic cylinder 3; a guide hole 13 with an opening at the left side and a coring hole 14 for communicating the guide hole 13 with the cavity 100 are formed in the female die 11;
the core pulling mechanism 2 comprises a sliding block 21 connected in the guide hole 13 in a sliding mode, a sliding groove 211 with an opening on the left side is formed in the sliding block 21, an adjusting block 22 is connected in the sliding groove 211 in a sleeved mode, a core pulling 23 is fixed at the right end of the adjusting block 22, and the core pulling 23 penetrates through the right side wall of the sliding groove 211 and the core pulling hole 14 and then extends into the cavity 100;
a connecting plate 24 is fixed at the left end of the sliding block 21, an adjusting screw 25 arranged in parallel with the loose core 23 is hinged on the connecting plate 24, and the adjusting screw 25 is screwed on the sliding block 21;
the connecting plate 24 is fixed with a connecting rod 26, the connecting rod 26 is fixedly connected with a telescopic rod of the telescopic cylinder 3, and the telescopic cylinder 3 is fixedly connected with the female die 11.
Furthermore, a pointer 27 is fixed on the outer wall of the adjusting screw 25, and the pointer 27 is opposite to a dial 28 formed on the connecting plate 24;
the dial 28 is arranged coaxially with the adjusting screw 25.
Furthermore, two through holes 212 penetrating in the left-right direction are formed in the sliding block 21, a hexagonal hole 213 is formed at the left end of one through hole 212, a hexagonal hole 213 is also formed at the right end of the other through hole 212, a hexagonal nut 29 matched with each hexagonal hole 213 is sleeved in each hexagonal hole 213, the hexagonal nut 29 is screwed in the middle of the screw rod 20, the middle of the screw rod 20 is inserted in the through hole 212, and two ends of the screw rod 20 are respectively hinged to the connecting plate 24 and the right side wall of the sliding groove 211.
