Abstract
The invention discloses an injection die, in particular to an injection die having a structure with three parts of parting surfaces. The injection die comprises a fixed die part, a moving die part and an ejector pin mechanism. When the fixed die part and the moving die part are in a die assembly state, a fixed die core of the fixed die part and a moving die core of the moving die part jointly form a product cavity used for the injection molding of a rotary switch cover with a through hole and with a concave and convex surface formed on the inner wall. The three separating processes of the three parts of parting surfaces of the injection die are simple. In the process of injection-molding one rotary switch cover with the through hole and with the concave and convex surface formed on the inner wall, the production failure rate is low, and the production efficiency is high.
Description
Technical field
The present invention relates to a kind of injection mold, the injection mold of parting surface structure at a kind of three.
Background technology
Injection-moulding plastic is one of high efficiency production method of plastic, is also a kind of important method of plastic shaping.It is primarily adapted for use in the molding of thermoplastic.Die joint be on mould for take out plastic or
Running gate system coagulates the separable contact surface of material.The design of injection mould die joint directly affects one of the key that the complexity of working of plastics quality, mould structure and operation is injection molding design success or failure.According to the quantity of die joint, single die joint injection mold and multiple parting lines injection mold can be divided into.
Ordinary circumstance multiple parting lines injection mold is more complicated than single die joint injection mold structure, manufacture requirements
High, cost height, but production efficiency is high.Divide by the position of die joint and be perpendicular to die sinking direction, be parallel to die sinking direction and favour several die joint in die sinking direction.Divide by the shape of die joint and have plane die joint
, curved surface die joint and stairstepping typing.During design mould of plastics, the selection of die joint is an important design content.Die joint selects reasonable mould simple, plastic easy-formation, and plastic part quality is high.If die joint selects unreasonable, mould structure becomes complicated, plastic parts moulding difficulty, and plastic part quality is poor.
Rotary switch covers on household appliances the most common, such as, and a kind of rotary switch lid stated in Fig. 1.Being formed with through hole on above-mentioned rotary switch lid, and be within it formed with male and fomale(M&F) on wall, therefore the rotary switch of said structure covers needs to combine core-pulling mechanism in injection molding needs to use multiple parting lines injection mold, and concrete mould structure.Existing, it is complicated to there is structure in the multiple parting lines injection mold of above-mentioned rotary switch lid, the technological deficiency that knockout course is loaded down with trivial details.
Summary of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art and the injection mold of parting surface structure at a kind of structure relatively simple three is provided.
To achieve these goals, the injection mold of parting surface structure at designed by the present invention a kind of three, including cover half part, dynamic model part and ejector pin mechanism, when described cover half part and dynamic model are partially in matched moulds state, the cover half core of its cover half part and the moving-mould-core of dynamic model part are collectively forming for injection mo(u)lding one band through hole, and form the product die cavity of the rotary switch lid of male and fomale(M&F) on inwall；
The cover half fixed plate of described cover half part is provided with the oblique shifting block forming a slanted angle relative to the die sinking direction of mould, described oblique shifting block sequentially passes through cover half frame and is articulated to the slide block on cover half frame, described slide block is provided with looses core, described loosing core runs through cover half core, and extend into the through hole to above-mentioned product type chamber, on molding above-mentioned rotary switch lid；
The side of the lower liftout plate of described ejector pin mechanism is provided with oblique pin base fixed plate, it is provided with in the side of described oblique pin base fixed plate and extends this oblique pin base fixed plate, but the telescopic block in oblique pin base fixed plate can be pressed into the most again, the dynamic model installing plate of described dynamic model part is provided with the guide holder forming groove on the stripping direction of mould, the groove groove face of described guide holder is provided with the first recess, above-mentioned telescopic block is positioned at this first recess, formed with consistent unilateral in direction that eject of thimble in ejector pin mechanism telescopic block can be pressed into the oblique section of oblique pin base fixed plate on above-mentioned first recess, it is movably equipped with in above-mentioned groove and carries block, the described block that carries fixes with the upper ejector plate of ejecting mechanism and/or lower liftout plate, carry block described in and and be provided with the second recess that can catch on above-mentioned telescopic block；Described oblique pin base fixed plate is provided with oblique pin base, described oblique pin base sequentially passes through lower liftout plate and the upper ejector plate of above-mentioned ejecting mechanism on the stripping direction of mould, and extend in the default through hole on the dynamic model frame of above-mentioned dynamic model part, and form T-shaped chute in its end, described T-shaped chute slidably connects the taper pin forming a slanted angle relative to the die sinking direction of mould, described taper pin runs through the moving-mould-core of above-mentioned dynamic model part, the male and fomale(M&F) on the inwall of molding above-mentioned rotary switch lid.
The injection mold of parting surface structure at above-mentioned provided a kind of three, comprises the die joint separation of three times in the whole knockout course of its injecting products.It is exactly specifically: first, before the cover half part of above-mentioned injection mold and dynamic model part carry out mold-break operations, the cover half of above-mentioned cover half part is installed version and is separated on the stripping direction of mould with cover half frame, now owing to being fixed with oblique shifting block on cover half installing plate, tiltedly shifting block linear motion on stripping direction can drive the slide block on cover half block to be subjected to displacement on the stripping direction be perpendicular to mould, thus drive is loosed core and is completed to detach from product type intracavity, hereto, the first die joint of above-mentioned injection mold completes to separate；Then, above-mentioned cover half part and dynamic model are partially completed die sinking action, and the second die joint of the most above-mentioned injection mold completes to separate；Finally, the ejector pin mechanism of above-mentioned injection mold starts action, its upper ejector plate and lower liftout plate are when ejecting injecting products by thimble from moving-mould-core, synchronize drives oblique pin base fixed plate to move along the direction that ejects of thimble by carrying block, until the oblique section that the telescopic block originally extending oblique pin base fixed plate side is directed on seat is pressed in oblique pin base fixed plate, now carry block oblique pin base fixed plate to be driven to continue with upper ejector plate and lower liftout plate eject at thimble and continue to move on direction by catching on telescopic block again, oblique pin base fixed plate drives oblique pin base to eject the adverse movement in direction toward thimble, the taper pin being slidably connected in the T-shaped chute of oblique pin base is subjected to displacement on the stripping direction be perpendicular to mould, hereto, the three parting line of above-mentioned injection mold completes to separate.
The present invention obtain a kind of three at the injection mold of parting surface structure, at the three of its injection mold, three separation processes of die joint are simple, at injection molding one band through hole, and during forming the rotary switch lid of male and fomale(M&F) on inwall, its fault in production rate is low, and production efficiency is high.
