Embodiment
As shown in figs 1 to 6, the present invention is that a kind of screen cloth compresses and the secondary injection mould of stretching, including solid plate
1st, fixed mold core 2, moving platen 3, mavable module core 4, arc compression block 5, push pedal 6, oil cylinder 7, more pull bars 8.
Described fixed mold core 2 is fixed on solid plate 1 and is higher by the bottom surface of solid plate 1, and the periphery of fixed mold core 2 opens up a circle
Block slots 21；The middle part of described moving platen 3 has a deep gouge 31, and mavable module core 4 is fixed on the center of the deep gouge 31 of moving platen 3,
There is the top surface of larger gap and mavable module core 4 in moving platen 3 between the outer wall of mavable module core 4 and the inwall of the deep gouge 31 of moving platen 3
Under the notch of deep gouge 31, there is about 35 centimetres of difference in height.The notch of the deep gouge 31 of moving platen 3 has circular arc chamfering R1（Such as Fig. 3
It is shown）.
Described fixed mold core 2 and mavable module core 4 are set relatively, and die cavity, fixed mold core 2 are provided between fixed mold core 2 and mavable module core 4
With all there is circular arc chamfering R2, R3 on the opposite face of mavable module core 4（As shown in Figure 3）.
Described push pedal 6 is arranged between solid plate 1 and moving platen 3 and gap is socketed on fixed mold core 2, and push pedal 6 is with moving
The faying face of template 3 is provided with the damping slot 61 of a circle above.Described push pedal 6 is connected by thimble rod 91 with ejector retainner plate 92.
The cylinder body of described oil cylinder 7 is fixed on the outer wall of moving platen 3, and the piston rod of oil cylinder 7 is fixedly connected on the outer of push pedal 6
Side simultaneously can drive push pedal 6 to move up and down, and in the present embodiment, described oil cylinder 7 has six.
Described arc compression block 5 is the circular arc convex of a whole circle, and the present embodiment height gets up 20；Centimetre, arc compression block 5 is in
Square（Or rectangle）, it is arc chord angle transition on its four angles, solid plate 1 and moving platen have arc chord angle R4 on 3 four angles
Transition（As shown in Figure 9）.The top of described arc compression block 5 is nested with the block slots 21 in the periphery of fixed mold core 2（As shown in Figure 8）
Interior, the bottom of arc compression block 5 is stretched out fixed mold core 2 and is resisted against on moving platen 3.
Multiple tie rod holes 22 are offered on described fixed mold core 2（As shown in Figure 8）And multiple tie rod holes 22 and block slots 21
Connection, gap is set in multiple tie rod holes 22 on fixed mold core 2 respectively on the top of more pull bars 8, the lower end point of more pull bars 8
It is not fixed in arc compression block 5.
The present invention may also include spring shim or spring；Described spring shim or spring is arranged on the block slots of fixed mold core 2
Between 21 and arc compression block 5, to adjust the height that fixed mold core 2 is stretched out in the bottom of arc compression block 5, if screen cloth spring is too tight, just
By this height reduction, if it is taut it is not tight enough if increase this height.
The operation principle of the present invention：
1st, push pedal 6 is raised 130MM with six heavy oil cylinders 7, pushed to together with the band of ejector retainner plate 92, allow the bottom of push pedal 6
There is space with the bottom of moving platen 3 to facilitate linked network cloth, while be also the step of product ejects.
The 2nd, screen cloth is hung over to the pipe nail 93 on moving platen 3（As shown in Figure 4）On, general tighten is done while extension.
3rd, this be the return of push pedal 6 state, at this time the power of six heavy oil cylinders 7 can make completely the bottom of push pedal 6 with
Dentation on the face of moving platen 3 stings tight screen cloth completely.
4th, oil cylinder 7 acts push pedal with ejector retainner plate 92 while returns to bottom, and push pedal 6 is to clamp completely with the face of moving platen 3
The state of screen cloth.Now, screen cloth 10 is crushed between moving platen 3 and push pedal 6, screen cloth 10（As shown in Figure 3）Periphery bypasses dynamic model
The notch of the deep gouge 31 of plate 3 has circular arc chamfering R1, the circular arc chamfering R3 on mavable module core 4, the arc lower surface, fixed of arc compression block 5
Circular arc chamfering R2 on die 2 and be tensioned, the cloth cover of stinging of moving platen 3 is to be higher by 35MM than mavable module core 4, current mould matched moulds again
When, screen cloth is tightened using this 35MM drop.
It is described above, only present pre-ferred embodiments, therefore the scope that the present invention is implemented can not be limited with this, i.e., according to
The equivalent changes and modifications that scope of the present invention patent and description are made, it all should still belong to the model that patent of the present invention covers
In enclosing.
