Description

The curved pin of angle takes out the structure of inner side core
Technical field
The present invention relates to the core-pulling mechanism of die cast metal mould and plastic injection moulding mould, it is the structure that the curved pin of angle takes out inner side core.
Background technology
When goods are recessed with inner side or during inboard aperture, side core-pulling must be first carried out before releasing, namely from goods, extract that molding side is recessed or the side core_pulling of side opening out, then goods could the demoulding smoothly, complete the inner side core-drawing mechanism that the extraction of side core_pulling and resetting-mechanism are exactly mould. Inner side core-drawing mechanism version common in prior art has: A, Angle Pin inner side core-drawing mechanism, and it is to utilize the Angle Pin being arranged in mould to rely on mould opening force to drive forming slide to be displaced outwardly in guide runner, reaches the purpose of side core-pulling. Though this mechanism compact conformation, reliable in action, convenient processing and manufacture, but it is not suitable for loosing core of the less goods of goods inside dimension. B, inclined guide inner side core-drawing mechanism, it is to utilize the thrust of ejecting mechanism to drive inclined guide to do lateral movement, is completed side core-pulling action by angled-lift splits while goods are pushed out. Though above-mentioned inner side core-drawing mechanism action is solid and reliable, convenient processing and manufacture, but goods such as the use said mechanism less for interior space dimension there will be the following defect: 1. owing to goods inner space is less, and Angle Pin inner side core-drawing mechanism is formed inner side core-drawing mechanism by parts such as Angle Pin, baroclinic block, angled-lift splits, slide guide parts, therefore its part is various, and this mechanism is used when goods inside dimension is less, cause manufacture, installation, inconvenient debugging. 2. according to the frame mode of inclined guide, inclined guide upper end is the molding position that goods side is recessed, and its mechanism is simple, easy to process, but easily produce horizontal overlap, part is yielding, overlap is yielding with product edges, and overlap and product edges are easily formed position deviation, affect the quality of goods. In order to overcome the deficiency of said mechanism, the following a kind of mechanism of special offer solves the problems referred to above.
Summary of the invention
The present invention is to provide the curved pin of angle and takes out the structure of inner side core, it is achieved in that when after injection or die cast, dynamic model part is rear under the effect of injector or die casting machine moves, now mould is opened between solid plate (55) and moving platen (135), and goods (75) move dynamic model one side to the rear shifting of dynamic model.Dynamic model part is moved after continuing, now the vertical plane K place end of run of the vertical plane t place on inner side core (85) and the curved pin of angle (35). at this moment the S place, inclined-plane of inner side core (85) contacts with the M place on the curved pin of angle (35), dynamic model moves after continuing, making sliding action to the left under the effect of inner side core (85) inclined-plane M on the curved pin of angle (35), then the moulding section of inner side core (85) is extracted out from the groove of goods (75) medial wall. when the vertical plane B place of die sinking to angle curved pin (35) front end stacks with the vertical plane R place on inner side core (85), at this moment the moulding section of inner side core (85) to extract out completely from the inboard groove of goods (75), and after there is the spacing of 3-5mm the end face of the moulding section of inner side core (85) and goods (75) medial wall, at this moment dynamic model part is mobile after stopping makees, then by the ejecting mechanism on mould by outside goods (75) launch mode. the curved pin of angle takes out the structure of inner side core, and it provides the benefit that: its simple in construction, compact, reliable in action, when its applicable die cast metal part and plastic injection part inside dimension are less, uses when being not convenient to use other core-pulling mechanism. the curved pin of angle takes out the structure of inner side core, solves the problem that Angle Pin inner side core-drawing mechanism part is various, be not easy to install and debug, solve that the inclined guide inner side core-drawing mechanism horizontal overlap of easily generation, part be yielding, overlap and product edges is yielding, overlap and product edges are easily formed position deviation problem. the curved pin of angle takes out the structure of inner side core, it is characterized in that: it is made up of cover half part and dynamic model part, its cover half part by: cover half backing plate (45), solid plate (55), the curved pin of angle (35) form, the curved pin of described angle (35) is arranged in the stepped hole of cover half backing plate (45), the curved pin of angle (35) through solid plate (55) afterwards, the front end matched moulds of the curved pin of its angle (35) time be arranged in the hole of dynamic model the first mold insert (115), the dynamic model part of this structure is by moving platen (135), Bottom clamp plate (125), dynamic model the first mold insert (115), dynamic model the second mold insert (105), dynamic model the 3rd mold insert (95), inner side core (85) composition, described moving platen (135) is provided with the die cavity of moulded products (75), the outside of the medial wall of goods (75) and dynamic model the second mold insert (105) is close to, described dynamic model the second mold insert (105) is arranged in the step through-hole of moving platen (135), the stepped hole of dynamic model the second mold insert (105) is provided with dynamic model the 3rd mold insert (95), the end face of described dynamic model the 3rd mold insert (95) becomes clearance fit with the lower plane of inner side core (85), the sidewall on dynamic model the second mold insert (105) the right is run through in described inner side core (85), the moulding section of inner side core (85) stretches in the groove of goods (75) medial wall, inner side is provided with a square oblique through hole in core (85) limit to the left in the heart, the square oblique through hole offered coordinates with angle curved pin (35) glade plane space, the inside of described dynamic model the 3rd mold insert (95) is arranged to through hole, after the curved pin of angle (35) runs through the through hole of dynamic model the second mold insert (105), the front end of the curved pin of its angle (35) is arranged in the through hole of dynamic model the first mold insert (115), described dynamic model the first mold insert (115) is arranged in the stepped hole of Bottom clamp plate (125).
