Specific implementation mode
Fig. 1-5 show related description figure of the present invention；The structure of product is as shown in Figure 1, product specification size is
381x342x81mm, average wall thickness 2.5mm, structure are open three face-pieces body, and injection forming mold design is needed to be considered heavy
Point problem is the following feature on product：1) T1 features, T1 features are located at product epivalve, including a depth capacity is
Irregularly open up in elliptoid groove and groove 2 of 5mmThrough-hole, 1Screw counterbore；2)T2
Feature, T2 features are located at the hypovalve of product, and feature structure form is identical as T1 features；3) T3 features, T3 are characterized as being located at upper
Numerous thickness of product front interior are 3mm between shell, lower casing, are highly the reinforcing rib of 6mm, spacing distance is between reinforcing rib
25mm；4) T4 features, T4 are characterized as diameterTowards it is preceding to depth be 41mm screw column；5) T5 features, T5 are special
Sign is that width is 7mm, and depth is the pointed grooves of 8mm；6) T6 features, T6 are characterized as prominent design and the cylinder on hypovalve
Shell cover, the axial line of centre bore and the stripping direction of reinforcing rib are in 39 ° of angles, and center-hole diameter isSide is set
In respect ofInstallation via；7) T7 is characterized as that the back side of product, upper and lower shell surface are formed after intermediate beam face connects
Straight slot；8) T8 is characterized as that the width opened up on product tail end medial surface in T7 straight slots is 14mm length 39mm, depth 2.4mm's
Open slot；In terms of the shape of product, structure is more complicated, but after feature decomposition, and T1~T8 feature structures are all simpler
It is single, be all the product structure design feature of plastic part routine, the demoulding of single feature is easier, but it is combined after design with originally
After on plastic part, due to the difference of stripping direction so that the demoulding design of product becomes complexity；
According to the characteristic distributions of the structure feature in before-mentioned products, using the face where L lines as main parting line, demoulding point 6
A to carry out step by step, i.e. the separation of forming part and product divides P1~P6 totally 6 directions progress；P1 is the main mold insert of cavity and production
The detaching direction of product T1 features, P2 be the main mold insert of core and product T2 features detaching direction, P3 be T7 features be molded mold insert and
The detaching direction of product, P4 be T8 features be molded mold insert and product detaching direction, P5 T3, T4, T5, T6 feature zoarium at
The detaching direction of type mold insert and product, P6 are characterized the detaching direction of 6 molding mold inserts and product；For demoulding mechanism design,
The separation in the direction P1, P2 can be realized using the die sinking of mold main parting line；The demoulding in the direction P3, P4 can then utilize simple
Undercut slide block mechanism realize；And for the parting in the direction P5, P6, though both direction is located at homonymy, due to
There are certain angles, and T3~T6 of this side is thus difficult to realize with simple single undercut sliding block for both direction
The demoulding in the directions P5 and the directions P6 need to be separated to carry out by the demoulding of feature, thus, corresponding demoulding mechanism design will be done certain
Structure innovation.

1) after being installed on mold, each slide block mechanism operation principle is as follows：
When die sinking, the first sliding block 8 is skidded off the demoulding for completing T7 features by the directions P3, and third sliding block 22 is skidded off by the directions P4
The demoulding of T8 features is completed, the second sliding block 20 is skidded off the demoulding for completing T3, T4, T5 feature by the directions P5, and Four-slider 27 presses P6
Direction, which skids off, completes the demoulding of T6 features；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-sliders 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 by being realized the method for 20 time-lapse core pulling of the second sliding block, i.e., driving the dynamic component of each 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 synchronizes, 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 move, and specifically set
Meter is as shown in Figure 5；In Fig. 5, as shown in G-G sectional views, to ensure 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 ensure both in the horizontal plane
Movement does not generate interference；To ensure that Four-slider 27 can realize core pulling distance D4, the distance that the 4th inclined guide pillar 26 need to move vertically
For D2, that is, ensure on the 4th inclined guide pillar 26 with the initial point d of point e point contacts and end of a period topmost in 27 slanting guide pillar hole of Four-slider
Vertical range difference between 2 points of point f 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 features, at this point, the b points on the curved pin of the second sliding block 21 just start to contact on the second sliding block 20
A points, the second sliding block 20 of driving presses the core pulling of the directions P5, when the c points until thereon completely disengage 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 20 priority core pulling of Four-slider 27 and the second sliding block,
D3 is to ensure 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 in conjunction with shown in Fig. 3, when die sinking, mold is opened at PL die joints, 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 waits for that delay distance D2 is finished, and it is special that the curved pin 21 of the second sliding block drives the second sliding block 20 to complete T3, T4, T5
The demoulding of sign, final product has thimble 32 to be ejected from the main mold insert of core 5, 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 is closed, and waits for next injection cycle.
Specific embodiment described herein is only an example for the spirit of the invention, technology neck belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
