31 shaft interconnecting piece 313 is connected, and after start-up operation, solid plate 2 and moving platen 3 mold, and injection molding machine first carries out a die cavity
Injection molding molds after completing primary injection molding, and fixed moving platen 32 rises under the drive of dynamic model connecting plate 4 and dynamic model support plate 5, revolves
Revolving die plate 31 rises and is rotated by 90 ° under the driving of shaft, while rotary template 31 is detached with fixed moving platen, then again into
Second of molding of row, injection molding machine are again molded a die cavity body, then mold again, driving of the rotary template 31 in shaft
Lower rising is simultaneously rotated by 90 ° again, and then third time molds, and is corresponded in a lower mode cavity 21 when due to one time, die cavity is molded
Be provided with pillar 23 on the position of the injection orifice 312 at the top of half die cavity 311, using one-time formed product force section position
On reserve a through-hole, when secondary cavity injection, soft plastic material is respectively from the injection orifice at 311 top of upper half die cavity
312 and the top of secondary half die cavity 322 be also provided with injection orifice 312 secondary injection be carried out at the same time to the positive and negative of one-pass molding product
Modeling, while quadric injection mould, the first die cavity is also once being molded, and after completing injection molding, molds rotary template 31 again again
Secondary to be rotated by 90 °, when molding for the 4th time, the thimble of 6 bottom of demoulding block of 4 side of dynamic model connecting plate, which passes through, completes quadric injection mould
Product automatic ejection upper half die cavity 311, the also fixed stripper plate in outside of the described demoulding block 6, the thimble in 6 bottom of demoulding block
It then extend into upper half die cavity 311 when pushing up shaped article downwards, stripper plate then pushes up downwards in the outside of shaped article simultaneously, keeps
Inside and outside stress equalization when product stripping, while primary injection molding and quadric injection mould are carried out at the same time in a die cavity and secondary die cavity,
Next work is exactly to repeat the continuous automatic production of action realization of the 4th molding.
Maximum feature of the invention is to correspond to the position of the injection orifice 312 at 311 top of upper half die cavity in a lower mode cavity 21
It sets and is provided with pillar 23, in mold clamping, pillar 23 can block the injection orifice 312 at 311 top of upper half die cavity, in this way complete
At the injection orifice being molded to product bottom after one-pass molding when the force section position of product can be reserved in quadric injection mould, simultaneously
The present invention corresponds to the rotary template runner 316 at the top of the second cavity and is connected to dynamic model plate runner 325 by being connected to runner 317, and
Rotary template runner 316 at the top of first cavity is not connected to 325 side of dynamic model plate runner, is achieved that in this way when second is molded
It carries out injecting soft plastic material in the positive and negative of one-time formed product simultaneously.
In addition the present invention is to use separate structure moving platen 3 there are one feature, due to rotary template 31 and fixed dynamic model
Plate 32 forms, and four groups of upper half die cavitys 311 are arranged in four sides of 31 bottom of rotary template, and the both sides setting of fixed moving platen 32 is primary
The upper half die cavity in half die cavity and secondary half die cavity, primary half die cavity and left side constitutes a upper cavity, secondary half die cavity and the right side
The upper half die cavity of side constitutes secondary upper cavity, also has two groups of upper half die cavitys 311 in the front side of rotary template 31 and rear side, respectively
For cooling station and demoulding station, to realize multistation post forming automatic demoulding.
For the present invention due to being adopted as the soft plastics such as silica gel or TPR when quadric injection mould, these tack of materials are stronger, different face
There are residue problems when color switches, and the residue problem after switching in order to avoid different colours, present invention employs cold runner, cold flows
Road can remain cured raw material after die sinking in runner, need to take away in next rear mold, and runner plate 7 of the invention is logical thus
The bottom that resin shutter is connected to dynamic model connecting plate 4 is crossed, every time when die sinking, runner plate 7 moves down centainly under gravity
Distance, so every time after injection molding, cured raw material can loosen and be partially disengaged injection through-hole, such manipulator energy side in runner
Just it is taken away from both sides by cured raw material.
