Specific embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Referring to figs. 1 to shown in Fig. 4, one kind of multiple back-off moulds, including front cavity 1, rear cavity 2, and the front cavity 1 with
The sliding block 3 set between rear cavity 2, the sliding block 3 is connected by a pair of Angle Pins 4 with the front cavity 1, the rear cavity 2
A rear mold mold insert 5 is connected with, the rear mold mold insert 5 is arranged in the side of the sliding block 3, the sliding block 3 and is provided with a thread spindle
6, against the rear mold mold insert 5, the other end is to be arranged on the drive end 61 on the outside of mould, the driving to the one end of the thread spindle 6
First gear 7 is connected with end 61, the side of the first gear 7 is engaged with second gear 8, and the second gear 8 is coaxially connected
There are the 3rd gear 9, and second gear 8 with diameter greater than the 3rd gear 9, the 3rd gear 9 is engaged with a tooth bar 10, tooth bar 10 1
End is arranged on the side of bottom plate 11, and the other end is offered in waist-shaped hole 101, the waist-shaped hole 101 and is provided with pin 12.
Further, the tooth bar 10 is arranged with parallel in one stroke plate 13, stroke plate 13 and offers chute 131, chute
Bolt is provided with 131.
Further, pin 14 is provided with the rear mold mold insert 5, the one end of pin 14 is connected with die cavity.
Further, sliding block pin 15 is connected with the sliding block 3, the one end of sliding block pin 15 is connected with die cavity.
