Through the bullet pin hole of sliding block 8, crank-guide way 84 is formed between the driver slot 83 and the bullet pin hole；
Drive block 2 is installed in the driver slot 83, spring groove, setting in the spring groove are formed in the drive block 2
There is driving spring 1, the both ends of the driving spring 1 connect with the slot bottom of the slot bottom of the spring groove and the driver slot 83 respectively
Touching；
The bullet pin hole is made of macropore 82 and aperture 85, and the macropore 82 is located at the right side of aperture 85, the macropore 82
Step 86 is formed between the aperture 85, is equipped in the bullet pin hole and plays needle 5, and ejection block 51, institute are formed on the bullet needle 5
It states to play and is also arranged with spring 6 on needle 5, the ejection block 51 is located in the macropore 82 with the spring 6, the spring 6
Both ends are in contact with the step 86 and ejection block 51 respectively；
It further include first connecting rod 3 and second connecting rod 4, the first connecting rod 3 and second connecting rod 4 are mounted on by pin shaft 32
On the crank-guide way 84, the both ends of the first connecting rod 3 and the second connecting rod 4 are formed with notch 31；
The bottom of the sliding block 8 is also formed with guide rail 81, and the guide rail 81 is equipped with the lower position block 7 of structure cooperation therewith,
The sliding slot of structure and the guide rail 81 cooperation is formed in the lower position block 7, guide rail 81 plays the role of slide guide to lower position block 7,
The lower position block 7 is fixedly mounted on dynamic model；
When mold clamping, the lower position block 7 and the drive block 2 are inconsistent, the notch 31 of 3 upper end of first connecting rod
It is in contact with the notch of 4 lower end of second connecting rod, the notch of 4 upper end of second connecting rod connects with the tail portion for playing needle 5
Touching.
In above-mentioned technical proposal: the upper left corner of the drive block 2 is formed with slope, and the slope includes starting inclined-plane 21 and top
Inclined-plane 22 out, the first connecting rod 3 and the equal bevel of notch on the second connecting rod 4, the upper end of the first connecting rod 3 lack
Inclined surface of connecting rod 311 is also formed on the inclined-plane of mouth 31, the lower end for playing 5 tail portion of needle, which is also formed with, plays needle inclined-plane 52.As shown in Figure 1,
The starting inclined-plane 21 of the drive block 2 is in contact with the notch 31 of 3 lower end of first connecting rod when molding, the first connecting rod 3
The notch 31 of upper end is in contact with the notch of 4 lower end of second connecting rod, the notch and the bullet needle of 4 upper end of second connecting rod
The bullet needle inclined-plane 52 of 5 tail portions is in contact, it is described play needle 5 head be located in the sliding block 8, it is described play 5 head of needle end face and
The surface of the sliding block 8 is generally aligned in the same plane, and is prevented product when injection molding from generating holes, is influenced formed product.
In above-mentioned technical proposal: it is described play pin hole right end be fixedly installed with prevent the ejection block 51 skid off it is described greatly
The upper limit position block 9 in hole 82, when mold clamping, the ejection block 51 and the upper limit position block 9 are inconsistent, prevent the head for playing needle 5
Portion is injection molding pressure extrusion and is excessively retracted in sliding block 8, and product is caused extra protrusion occur, influences formed product.
The course of work of the invention is as follows, and injection molding machine molding, which finishes, to be started to be molded, and lower position block 7 is located at guide rail 81 at this time
