The application method of above-mentioned mold is also disclosed, steps are as follows: mold working principle are as follows:

1) after installing on mold, each slide block mechanism working principle is as follows:

When die sinking, the first sliding block 8 is skidded off the demoulding for completing T7 feature by the direction P3, and third sliding block 22 is skidded off by the direction P4 The demoulding of T8 feature is completed, the second sliding block 20 is skidded off the demoulding for completing T3, T4, T5 feature by the direction P5, and Four-slider 27 presses P6 Direction, which skids off, completes the demoulding of T6 feature；Figure 4, it is seen that if Four-slider 27 and the second sliding block 20 synchronize skid off, gesture The 4th inclined guide pillar 26, Four-slider 27, the 4th wedge block 28 of Bi Four-slider mechanism will generate interference with the second sliding block 20, Thus, preferable method is that Four-slider 27 is first allowed to complete core pulling to concede space to the second sliding block 20, so need to be to the Four-slider 27 and skidding off for the second sliding block 20 do Curve guide impeller and arrangement in structure, and the sequencing core pulling to realize the two is dynamic Make, solution is will to drive the dynamic component of each sliding block by realizing the method for 20 time-lapse core pulling of the second sliding block The curved pin 21 of first inclined guide pillar 6, the second sliding block, third inclined guide pillar 24, the 4th inclined guide pillar 26 etc. are installed on stationary mould for mould side, die sinking The movement of Shi Sizhe is synchronous, but the sliding block driven is then asynchronous, the first sliding block 8, third sliding block 22, Four-slider 27 3 Sliding block, which first synchronizes, laterally does core pulling campaign, and after waiting Four-slider 27 to complete core pulling campaign, the second sliding block 20 could be moved, and specifically set Meter is as shown in Figure 5；In Fig. 5, as shown in G-G cross-sectional view, to guarantee that Four-slider 27 can be before the 20 core pulling campaign of the second sliding block First complete core pulling action, the design of Four-slider 27 is installed on the beneath of the second sliding block 20, to guarantee both in the horizontal plane Movement does not generate interference；To guarantee that Four-slider 27 is able to achieve core pulling distance D4, the distance that the 4th inclined guide pillar 26 need to move vertically For D2, i.e., on the 4th inclined guide pillar 26 of guarantee with the initial point d of point e point contact and end of a period topmost in 27 slanting guide pillar hole of Four-slider Vertical range difference between point f two o'clock is D2, and after mold die sinking distance realizes D2 length, the 4th inclined guide pillar 26 has driven the 4th Sliding block 27 realizes the side core-pulling of T6 feature, at this point, the b point on the curved pin 21 of the second sliding block just starts to contact on the second sliding block 20 A point, the second sliding block 20 of driving presses the core pulling of the direction P5, when the c point until thereon completely disengages the second sliding block 20, realizes the second sliding block The side core-pulling distance of 20 D1 length；So D2 length is the delay distance of Four-slider 27 and the successive core pulling of the second sliding block 20, D3 is to guarantee that the second sliding block 20 realizes the die sinking distance of core pulling distance, and the minimum die sinking distance of mold is D2+D3.

2) mold die sinking is single parting, and as shown in connection with fig. 3, when die sinking, mold is opened at PL die joint, after dynamic model Move back after distance is D2,27 3 the first sliding block 8, third sliding block 22, Four-slider sliding blocks first complete core pulling action, realize T1, T6, The demoulding of T7, T8 feature, wait be delayed, distance D2 is finished, and the curved pin 21 of the second sliding block drives the second sliding block 20 to complete T3, T4, T5 feature Demoulding, final product has thimble 32 to eject from the main mold insert 5 of type core, to realize the complete demoulding of product；

When reset, process is that the second sliding block 20 first resets again on the contrary, thimble 32 first resets, and is remaining sliding block after last It resets, mold closure waits next injection cycle.

The specific embodiments described herein are merely examples of the spirit of the present invention, the utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
