The operation principle of above-mentioned technical proposal is：
Wherein, dynamic model includes a dynamic model and secondary dynamic model；
One-pass molding
Double-color mold is opened, primary side shovel base 2 is connected on a dynamic model, sliding block 1 is movably coupled to double-colored
On the cover half of mold and slide block insert is made to be inserted into double-color mold, cover half and a dynamic model (not shown) molding mistake
Cheng Zhong, a dynamic model will drive primary side to shovel base 2 and be moved towards sliding block 1 and in the sliding slot 11 that is inserted into, finally make buffering suface 12 with
Secondary contact surface 21 contacts with each other, and makes the molding of double-colored module and completes the one-pass molding of product (not shown)；Delay at this time
There is no active force between impulse face and a contact surface；Make double-color mold die sinking that primary side shovel base 2 be made to be detached from sliding slot 11 again, slides at this time
Block 1 remains in situ motionless；
Post forming
Cover half is turned into (not shown) at secondary dynamic model, secondary side shovel base 3 is connected on secondary dynamic model；Two
During secondary dynamic model and cover half mold, secondary dynamic model will drive secondary side shovel 3 mobile towards sliding block and be inserted into sliding slot 11,
Finally buffering suface 12 is made to contact with each other with secondary contact surface 31, so that double-color mold is molded and complete the post forming of product；
In the clamping process of post forming, removable pin 41 is contacted with approaching face 321 first；As post forming molded
Journey continues, and removable pin 41 will be moved to land area 322 from approaching face 321, and be moved on land area 322, at this time spring 43
It receives extruding force and shrinks；When post forming buffering suface 12 and secondary contact surface 31 contact, removable pin 41 will be from land area 322
It is moved to the position of supporting surface 324, removable pin 41 is bound on supporting surface 324 at this point, spring 43 discharges elastic force, makes removable pin 41
It is contacted with supporting surface 324 backwards to one end of spring 43, meanwhile, the side of removable pin 41 is contacted with core pulling face 323；
Core pulling operates
After the completion of the post forming of product, double-color mold is molded, secondary side shovel base 3 will be carried on the back with secondary dynamic model
It is moved to cover half, sliding block 1 will be because of relative displacement between secondary side shovel 3 at this time, and removable pin 41 is made to be rolled on core pulling face 323
It is dynamic；Due to forming acute angle between core pulling face 323 and the moving direction of sliding block 1, with making removable pin 41 and core pulling face
Relative displacement between 323 will generate sliding block 1 power backwards to cover half direction so that sliding block is slided backwards to cover half, and then makes cunning
Block 1 extracts slide block insert out out of double-color mold, completes core pulling operation.
Therefore the technical program only need to need not once be taken out using ejecting mechanism, i.e. the injection molding work of double-color mold twice
The manufacture work of product can be completed in core, avoids relationship of the product after one-pass molding due to contraction, slide block insert again
The case where being easy to insert injured labour product, fraction defective is caused to improve when being deep into double-color mold；Solves the big core pulling of double-color mold
1 problem of sliding block；On big sliding block 1, it can no longer be made to reduce mold thickness using ejecting mechanism twice
Volume production is carried out with smaller molding machine, has effectively saved cost；Meanwhile the technical program simple shape, handling ease, also easily
In adjusting, performance can be met.Also it is effectively saved cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
