Description

Active and inactive mold is threaded looses core and the mold mechanism loosed core in the side
Technical field
The present invention relates to metal crimp mold and injection-moulding plastic mould, being that a kind of active and inactive mold is threaded looses core and the side mold mechanism of loosing core.
Background technology
After die cast and injection moulding, around the product or two ends, when having goods products such as hole, depression, boss, screw thread, the general part that can be displaced sideways or rotate of all will making of the part at this place of moulding on the mould, so that before the demoulding, take out side direction forming part or thread part earlier, otherwise just can't the demoulding.Make the boundary at mould at present, according to the power resources difference, that undercut and core-pulling mechanism can be divided into is motor-driven, hydraulic pressure or pneumatic reaching are manually loosed core.Motor-driven somatotype and core-pulling mechanism are to utilize injector or die casting machine mould opening force as power, exerting all one's strength by relevant driving parts (as Angle Pin) acts on the side direction forming part and extracts out from goods with the mould undercut or the side direction core, by it the side direction forming part is resetted again during matched moulds.Though this class mechanism is complicated, somatotype is with loose core need not manual operation, and the productivity ratio height is widely used aborning.And hydraulic pressure or pneumatic somatotype and core-pulling mechanism are to be used as power with hydraulic coupling or atmospheric pressure to carry out somatotype and loose core, same hydraulic pressure or the atmospheric pressure of relying on resets, its suitable somatotype and core-pulling mechanism withdrawing power are big, loose core apart from long occasion, this class somatotype and core-pulling mechanism are the realizations that moves back and forth of the piston by hydraulic cylinder, the stable action of loosing core, easily manufactured.Manually somatotype and core-pulling mechanism are to utilize manpower to loose core from moulded products with the mould somatotype or the side direction core.This class mechanism inconvenient operation, labor strength is big, and productivity ratio is low, but mould structure is simple, and processing cost is low, is usually used in trial production, and small lot batch manufacture maybe can't be adopted the occasion of other somatotype and core-pulling mechanism.Merits and demerits separately now is combined in the mould design circle design experiences of two more than ten years in person in sum, and is special to promoting following a kind of mold mechanism in the industry.
Summary of the invention
The present invention provides that a kind of active and inactive mold is threaded looses core and the side mold mechanism of loosing core, it mainly is fit to goods two ends or side screw thread or boss, metal crimp foundry goods or injection molding members such as pit, this mechanism is applied widely, the mold mechanism automaticity is very high, move solid and reliable, the pressure transmission is very good, be fit to the automated production of modernized factory, opening period is short, the productivity ratio height, but the Tool and Die Technology content of this mechanism is very high, require the technical capability of design and manufacturer very high, die cost is higher simultaneously, installs and debug difficulty, and the accuracy of manufacture requires very high.

The specific embodiment:
Loose core and the side mold mechanism of loosing core for active and inactive mold is threaded shown in the figure.When its was fit to metal crimp mold and injection mould moulding, goods were very complicated, and a kind of mold mechanism that adopts other simple mechanism to be adopted can't moulding the time, its design simultaneously and require when making highly, and technology content is big.Its concrete measure is as follows: when the mould clamping is in injector or die casting, after the power injection of former and die casting finish, mould at first can not be opened, but extract the cover half thread core earlier out, extract cover half core 31 out, at first be mounted in the hydraulic jack action on the mould cover half, outwards twitch because the power of hydraulic jack 3 drives tooth bar 4, and twitch driven gear 35 rotations of tooth bar 4.Because the rotation of gear 35 just drives 31 rotations of cover half thread core.The rotation of thread core 31 makes its goods screw thread and core partly loosening, and cover half push pedal at this moment 6 also begins action under the power effect of spring 33, and move after at this moment dynamic model continues, in this case, while rotating, the cover half core under the effect of cover half push pedal, deviates from goods partly in the cover half moulding.Move after dynamic model continues, the slide block of side amalgamation at this moment 29 and 36 also begins do the side start of loosing core.Side slide 36 is at the effect bottom right side core-pulling of Angle Pin 10, deviate from goods side recess part fully until side slide, and when being arranged, the spacing of 2-3mm stops action, left slider is made the left side horizontal movement under the effect of hydraulic jack 28, when the slide block moulding section breaks away from goods fully, just stop action, at this moment cover half core and left and right sides slide block have broken away from goods fully, dynamic model moves after continuing, goods stay fully on dynamic mould core 21, to deviate from product outside the mould, at this moment dynamic model one side's hydraulic jack begins action, because the power of hydraulic jack 17, forces tooth bar 18 to move as the right side, parallel right side moving belt moving gear 22 rotations of tooth bar 18, gear 22 drives 21 rotations of dynamic model thread core.The rotation of thread core 21 makes goods and the loosening package power that reduces of thread core, and thread core continues rotation, at this moment under the effect of dynamic model push pedal 12, under the effect of spring 25 push pedal is upspring while revolve rotor plate push pedal 12, because upspringing of dynamic model push pedal, goods 11 are deviate from dynamic model fully.During matched moulds, it is closed fully up to mould A-A and B-B die joint that rightabout action is done in above-mentioned action, just stops action.More than action is back and forth produced in batches.

Claims (1)

1. active and inactive mold is threaded looses core and the side mold mechanism of loosing core.The characteristics of this mechanism are: internal thread all is with at the goods two ends, and the goods side is fluted, and a kind of mechanism that adopts.In order to reach the purpose of product, after this mechanism must deviate from cover half screw thread partly earlier, the mould die joint just can be opened, and then remakes the side and looses core, when the cover half screw thread deviate from deviate from goods fully with side slide after, the dynamic model thread core could rotate looses core goods.This mechanism is with high content of technology, product is very graceful, is fit in die cast metal mould and the injecting molding die, and article shape complexity and threaded goods adopt this mechanism, another characteristics are these mechanisms because with high content of technology, and are very high to designer and producer's specification requirement.Particularly the accuracy of each parts is very high during fabrication, but product quality and precision also improve with the smart high of mould, and automaticity is high simultaneously, is fit to the automated production of modernized factory.The economic worth of promoting the use of is arranged.
