Embodiment

Slide block insert 12 is fixed by screws on take-up housing 19, Double-ejection mandril i.e. the first mandril 8, the 4th mandril 11 With the second mandril 9, third mandril 10 in slide block insert 12 in the following, Double-ejection mandril i.e. the 5th mandril 14,15 and of the 6th mandril At mold Y-direction center, cast gate is arranged in slide block insert 12 in the following, if Double-ejection top for 7th mandril 16, the 8th mandril 17 Bar, the 5th mandril 14, the 6th mandril 15 and the 7th mandril 16, the 8th mandril 17 delayed ejection distance be S, then Double-ejection The delayed ejection distance of mandril the first mandril 8, the 4th mandril 11 and the second mandril 9, third mandril 10 is set as S+2, they it Between must have the ejection drop of 2mm or so, cast gate form design is at such as Fig. 7, and 8,9 special shapes, side gate a part is in sliding block Above mold insert, a part does 1 ° of angle in the cast gate bottom surface of Slipper, the cast gate in insert on insert Do 30 ° of angles in bottom surface.It is realized by the special patterns of the different delay time control of Double-ejection mandril at two and cast gate Side gate is automatically cut off.

This mold is side gate, it is desirable that automatic break gate is first made into cast gate such as Fig. 7,8,9 pattern exists The cast gate of insert part is made into the small inner big back taper form (as shown in Figure 8) of mouth, the gate portions in slide block insert 12 It is made into long strips (as shown in Figure 9), if the gap between the 6th mandril 15 and the 8th mandril 17 and ejector plate 6 is S, Then the gap between third mandril 10 and the 4th mandril 11 and ejector plate 6 should be S+2, there is the ejection of 2mm or so between them Time difference, when mold die sinking is completed to do ejection movement, product is first ejected, and ejection distance is greater than the 5th mandril 14 and the 7th after S Mandril 16 starts to eject runner, and the first mandril 8 and the second mandril 9 are still within invalid state, then eject the first mandril after 2mm 8 and second mandril 9 just start eject runner, since cast gate is inverted cone-shaped in insert part, thus product ejection when pour Always runner just really starts ejection movement, i.e. product to mouth in insert, and after the distance of only product ejection S+2 There is a relative motion between runner, move distance S+2, so at this moment cast gate alreadyes switch off and leaves product, i.e., it is successfully complete It is automatically cut off at side gate.
