Fig. 8 and Fig. 9 are the structural representation of stripper apparatus of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

See Fig. 1 to Fig. 9, the present invention includes and comprise die shoe 1, on die shoe 1 with the first dynamic model 2, the second dynamic model 3, the 3rd dynamic model 4 and the 4th dynamic model 5 that can move horizontally; The second dynamic model 3 and the 4th dynamic model 5 arrange in opposite directions, the 3rd dynamic model 4 and the vertical setting of the 4th dynamic model 5, the first dynamic model 2 and the oblique setting of the 4th dynamic model 5, according to product dust catcher point bucket structure, oblique setting more can improve the demoulding efficiency of mould, guarantees production efficiency and product quality; The die holder sidewall of the first dynamic model 2, the second dynamic model 3 and the 4th dynamic model 5 is all curved, and the die holder sidewall of the 3rd dynamic model 4 is with arc boss 41, and boss 41 can generate the U-shaped connecting portion on circle product external during for injection moulding; On die shoe 1 with center counterbore 11, counterbore 11 is built-in with cylindricality core rod 8, core rod 8 end faces are with running channel 81 and be pressed with cast gate 6, each sidewall of core rod 8 and the first dynamic model 2, the second dynamic model 3, the 3rd dynamic model 4 and the 4th dynamic model 5 can form certain interval, by the inside injected plastic raw material of cast gate 6, can in described gap, form product as shown in Figure 1 along running channel 81; On die shoe 1, be with fluted 12, in groove 12, be fixed with briquetting 13 with the first dynamic model 2 and in groove 12 both sides, step on the first dynamic model 2 bottoms is between briquetting 13 and groove 12 bottom surfaces, pull bar 14 is connected on the first dynamic model 2, pull pull bar 14 can drive the first dynamic model 2 in the interior movement of groove 12, briquetting 13 plays the effect of guiding and location; On the first dynamic model 2, with caulking groove 21, stripper apparatus 7 is housed in caulking groove 21, stripper apparatus 7 comprises base 71, on base 71, with oblique locating hole, with drawing pin 76, draws the end of pin 76 contiguous block 77 that is connected in described locating hole; The end of base 71 is with voussoir 79, the both sides of voussoir 79 are all with T shape slide block 73, voussoir 79 is flexibly connected a pair of knock-outs will 74 by T shape slide block 73, in knock-outs will 74 with de-the first mould post 75, the first mould post 75 is for pouring into a mould out the pin-and-hole 91 of product, preferably, T shape slide block 73 coordinates with the T shape chute 78 in knock-outs will 74, can improve the guiding accuracy of slide block, simultaneously in the time drawing pin 76 to move upward to drive base 71 to move horizontally, can make the horizontal move toward one another of a pair of knock-outs will 74, dwindle the distance between a pair of de-the first mould post 75, make the smooth demoulding of product; The sidewall that the second dynamic model 3 is relative with the 3rd dynamic model 4 with the 4th dynamic model 5 can generate another pin-and-hole on product with the second mould post 31, the second mould posts 31; Preferably, the bottom of base 71 is with inserting 72, and base 71 72 coordinates with the guide pad 9 in caulking groove 21 by inserting, and guide pad 9 is conducive to guarantee the mobile accuracy of base 71 in caulking groove 21, and guide pad 9 72 makes by high-abrasive material with inserting, can improve its service life;

Demoulding principle of the present invention is as follows:

After the full mould of mould, injection moulding liquid enters running channel 81 from cast gate 6, then enter core rod 8 and the first dynamic model 2, the second dynamic model 3, the gap that each sidewall of the 3rd dynamic model 4 and the 4th dynamic model 5 forms, after casting complete, starting patrix (not shown in FIG.) drives contiguous block 77 to move upward, and then make to draw pin 76 vertical translations, be oblique setting owing to drawing the relative base 71 of pin 76, can apply horizontal force to base 71, base 71 is moved horizontally in caulking groove 21, make the horizontal move toward one another of a pair of knock-outs will 74 simultaneously, dwindle the distance between a pair of de-the first mould post 75, de-the first mould post 75 is deviate from smoothly in the pin-and-hole 91 of product, last under the pulling of pull bar 14, the first dynamic model 2 is in the interior movement of groove 12, make whole the first dynamic model 2 depart from circle product external, can take out the finished product of cast.

More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
