The utility model discloses a kind of molding mold cavity side core-pulling anticollision mechanism, after working of plastics injection moulding, bullet
Spring promotes die cavity to move down in the presence of restoring force, and die cavity drives working of plastics, core, support block, upper ejector retainner plate, lower thimble
Plate, thimble, lower compound plate are moved down, and backing plate and fixed block are remained stationary as, and mould is gradually opened from backing plate and die cavity, by
One of side core-pulling bar in the oblique chute of fixed block has held die cavity, therefore in die cavity while moving down, side core-pulling
Bar is gradually extracted out laterally along the incline direction in side core-pulling hole and the incline direction of oblique chute, and side core-pulling bar drives side core-pulling
Block extracts the inclined hole of working of plastics out, and after completing core pulling, in the presence of twice-die-opening controlling organization, mould is beaten from die cavity and core
Open, now drive upper and lower ejector retainner plate, upper and lower ejector retainner plate to drive thimble by the upward ejection device of working of plastics by oil cylinder.This programme
Molding mold cavity side core-pulling anticollision mechanism, by setting side core-pulling bar and side core-pulling block in die cavity, sets solid in backing plate outer wall
Determine block, oblique chute is formed with fixed block, spring is set between backing plate and die cavity, when molding mould first from backing plate and die cavity
Once mold, using side core-pulling bar and the spacing cooperation of the slip of oblique chute, side core-pulling block is first deviate from the inclined hole of working of plastics, so that
Ensure injection mold when being molded at die cavity and core can smoothly by working of plastics ejection device, its relative in core side core-pulling,
Avoid being collided with straight thimble or oblique top pin, and structure is simpler.
The utility model molding mold cavity side core-pulling anticollision mechanism, described twice-die-opening controlling organization includes once opening
Die drawing bar, twice-die-opening pull bar and dead bolt, described once die sinking pull bar are mutually fixed through fastener with backing plate, are drawn in once die sinking
A drag hook is formed with bar, one time the upper surface of drag hook is oblique surface, and described twice-die-opening pull bar is through fastener and core phase
It is fixed, secondary drag hook is formed with twice-die-opening pull bar, the lower surface of secondary drag hook is straight block face, is opened in described die cavity outer wall
Have mounting groove, dead bolt and little spring be set in mounting groove, little spring is in contact with dead bolt, be formed with dead bolt face directly with it is oblique
Face, above faces directly and is in contact with the straight block face of secondary drag hook, and lower inclined plane is in contact with the oblique surface of a drag hook.When mould is in die sinking
When, because the straight block face of the secondary drag hook lower end of twice-die-opening pull bar is engaged with being faced directly on dead bolt, secondary drag hook holds lock
Tongue, now mould cannot be opened from die cavity and core, and can only for the first time be molded from die cavity and backing plate；Locked when die cavity drives
When tongue is moved downward to an once drag hook position of die sinking pull bar, the lower inclined plane of dead bolt connects with the oblique surface of a drag hook
Touch, dead bolt under the mating reaction of oblique surface and lower inclined plane inwardly in the mounting groove of retraction die cavity, now dead bolt with once mold
Pull bar and twice-die-opening pull bar are all disengaged, and now mould can be from twice-die-opening at die cavity and core.Set on described dead bolt
Limited block is put, limited block is mutually fixed through fastener with die cavity, limited block lower end is spacing with dead bolt to be contacted.There is limited block, it is to avoid
After mould die sinking, dead bolt is ejected into mounting groove in little spring restoring force.Described spring is nitrogen spring.Using nitrogen spring,
Improve operating efficiency.
