Working principle and beneficial effect
When work, upper mold 1 and lower die 2 are in die opening state；
Step 1 opens core block 211, embedded A inserts 02 and B inserts 03；
Starting oil cylinder 220 pulls C racks 221 to move right, coupled gear 223 drive D racks 222, connection shifting block 225 to
Preceding movement, the allocating slot 2251 for joining shifting block 225 drive core sliding block 228 to move forward through driving lever 224, and core sliding block 228 is cut with scissors through core
Chain 2281 drives core block 211, and the slide guide axis 2111 of core block 211 is made to hook 213 sliding slot sliding, slide guide along the slide guide
Hook 213 makes core block 211 be rotated up to detach opening, later, people with the cavity block 212 with the collective effect of core hinge 2281
Work is by A inserts 02 and B inserts 03 at the chamber side 2120 of cavity block 212；
Step 2, core block 211 reset；
Starting oil cylinder 220 pushes C racks 221 to be moved to the left, and one process of inverse step makes core block 211 reset, later, on
Mould 1 is molded with lower die 2, and injection molding connects angle 04；
Step 3, product 01 demould,
Upper mold 1 is molded with lower die 2, repeats step 1 process, artificial to take out product 01, is embedded in A inserts 02 and B inserts again
03, core block 211 resets, and upper mold 1 is molded with lower die 2, and injection molding connects angle 04, so in cycles；
The pushing top spring 229 act as pushing up ejector half support plate 21 when demoulding and moving up, core block described in power-assisted
211 overcome adhesive force to be detached from the cavity block 212 with product 01；The damping torsional spring 226 act as damping stable C racks
The movement of 221 and D racks 222, prevents from jumping.
When practical application, the present apparatus is run using double-station injection molding machine, using 1 two oil cylinders of a upper mold, 220 position phase
To lower die 2, upper mold 1 is located at the up and down work Liang Chu on double-station injection molding machine top, and two lower dies 2 are correspondingly arranged at double side by side
At the double-station horizontal mobile work platform of station injection molding machine lower part；
If the left part of the double-station horizontal mobile work platform of double-station injection molding machine lower part is E stations, right part is F stations；
When work, when the lower section mold-closing injection molding that the lower die 2 positioned at F stations moves to upper mold 1 connects angle 04, it is located at E works
The lower die 2 of position can carry out demolded article 01 and the work for being packed into A inserts 02, B inserts 03, equally, when the lower die positioned at E stations
When the 2 lower section mold-closing injection moldings for moving to upper mold 1 connect angle 04, it can carry out demolded article 01 positioned at the lower die 2 of F stations and be packed into
The work of A inserts 02, B inserts 03；Such course of work is known as double-station injection molding and connects angle molding, thus the present apparatus is referred to as duplex
Position injection molding connects angle molding die.
The present apparatus is driven by oil cylinder 220 opens and resets core block 211, avoids manpower and pulls, it is strong to alleviate work
Degree；Angle molding is connect using double-station injection molding and avoids craftsmanship shutdown, production effect is improved by not shutting down to stagger the time to work continuously
Rate.
