Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment: refer to Fig. 1 to Figure 12, the compound demolding structure of one, including outside core 1, interior core 2, pushing block 3 and guide rod 4,
Outside core 1 therein is the core of moulded products breach, and interior core 2 is the core of moulded products snap fit, and outside core 1 is enclosed within inner mold
Core 2 top, outside core 1 sidewall opening, pushing block 3 passes outside core 1 sidewall opening 101 and is inserted into the groove of interior core side
In 201, pushing block 3 drives interior core 2 to move up and down relative to outside core 1, and interior core 2 bottom is provided with guide runner 202, guide runner
Being provided with guide rod 4 in 202, described guide runner 202 is made up of straight trough and helicla flute, and in guide runner, spiral fluted lead angle is 30-
70 degree, preferably 65 degree, advantage be transmission more relax, smooth and easy, it is to avoid self-locking.In journey of dividing a word with a hyphen at the end of a line on interior core 2, gathering sill is at guide rod
Inside and outside core is made first to be layered to rotate afterwards and realize goods automatic demoulding under guiding.Outside core 1 sidewall opening 101 of the present invention is along type
Core is axially extending, and the groove 201 of interior core 2 is arcuation groove circumferentially extending along interior core, and the circumferential width of arcuation groove is to meet
The anglec of rotation that article removal requires is as the criterion.Outside core sidewall is provided with one or more opening, in order to improve stability, and outside core
1 sidewall symmetry be provided with opening, two pushing blocks 3 are inserted in the groove 201 of interior core 2 side-fit through corresponding opening.This
Bright described interior core sidewall is provided with 1 guide runner or more than a plurality of guide runner of 1, such as Figure 13, shown in 14, and interior core 2 sidewall
Being arranged with two guide runners with axis, each guide runner is to be made up of straight trough and helicla flute and coordinate with a guide rod, guide runner
Be the guide barrel construction having and making gradient from interior core wall outer surface to inner surface, the gradient of described guide runner is that α angle is
10-50 degree, preferably 30 degree, guide runner exterior notch radially is more than inner tank mouths, and the guide rod matched is the work with α pyramid degree
With end.When assembling mould, being provided with at least one thimble to eject in goods in interior core 2, thimble can be one or two,
Example thimble quantity shown in Fig. 8 is two, and thimble 203,204 nested type is placed in interior core quill shaft intracavity.Such as Fig. 6, figure
7, outside core 1 of the present invention coordinates with outside core fixed plate 14, is provided with base plate 5 bottom interior core 2, and guide rod 4 coordinates with guide rod plate 6,
Interior core 2 is provided with sleeve 7 between guide rod plate and base plate.As shown in Fig. 8, Fig. 9, Figure 11, Figure 12, compound demolding structure is arranged on
Lower mold 8, lower mold 8 coordinates with upper mold 9 and realizes goods injection, and lower mold 8 is provided with the spring 801 driving pushing block action, and it is fixed that spring is placed on
On bolt 802.Such as Figure 10, Figure 11 and Figure 12, between lower mold 8 and upper mold 9, be provided with die button 10, die button 10 include button 101, under
Button 102 and middle slide fastener 103, upper button 101 is connected with upper mold 9, and lower button 102 and middle slide fastener 103 are connected with lower mold 8, upper button 101
With middle slide fastener 103 snapping so that upper and lower mould matched moulds, during die sinking in the middle of slide fastener 103 buckle 102 and coordinate with lower and drive the mould that is connected
Plate and inside and outside core typing and deviate from goods snap fit.Fig. 9, Figure 11, Figure 12, upper and lower mould is provided with two goods injection die cavities and joins
Two groups closed are combined demolding structure, and the two interior core linkages being combined demolding structure realize the demoulding.
The snap fit of Fig. 1 breather valve joint is by the core (outside core 1) of the core (interior core 2) of molding snap fit Yu shaped notch
After first layering is staggered, interior core rotates 41 degree again, could be by completely out for core goods.The feature of the demoulding according to plastic,
Producing the guide runner 202 being made up of one section of straight trough and helicla flute on interior core 2, guide runner is under the guiding of guide rod 4, so that it may with
Realize die sinking automatic demoulding.And the female thread of breather valve joint may utilize die sinking tooth bar 901 driven gear and rotates the strand tooth demoulding,
Effective die sinking distance and the length of tooth bar in view of injection machine. using two-stage transmission, modulus selects 1, the first gear and second
Gear ratio is 3:1, the 3rd gear and the 4th gear ratio 2:1, and drive system is than for 6:1.
The demoulding of plastic/eject:
During die sinking, under the effect of spring 801 and die button 10, at I, be first begin to typing, pushing block 3 drive interior core 2 forward (on)
Motion, the most forward (on) mobile 3.5mm, then to left-handed 41 degree, at this moment the typing at I has arrived distance bolt 802 (spring
Set thereon) stroke-limit, stop motion, the snap fit of the interior completely out goods of core 2.Then typing is started at II, all
Gear be all engagement, the first gear rotates on tooth bar 901, thus drives core gear shaft 803,804 with the speed of six times
Degree rotates, and deviates from .803,804 is core gear shaft from goods, and 805 is tin bronze nut, the pitch phase of pitch and plastic
With, so, along with the rotation of core gear shaft, core can be deviate from, automatically without injuring the threaded portion of goods from plastic.
The die sinking distance controlling of mould, in the spacing stroke of distance plate, makes tooth bar 901 without departing from the engagement of gear. guarantee safety
Matched moulds. finally by thimble (52), plastic is ejected.
Described above, only utilize the embodiment of this origination techniques content, any those skilled in the art to use this wound
Make modification, the change done, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
