Abstract
The invention provides an internal core-pulling mechanism for an inclined hole of an injection-molded plastic piece. The internal core-pulling mechanism comprises an upper mold plate and a lower mold plate; the upper template is connected with a cavity; a top plate and a mold foot are arranged on the lower mold plate; a mold core is arranged on the mold foot; the mold core and the cavity form a mold cavity; a molded plastic piece is arranged in the mold cavity; a straight top rod is arranged on the top plate; the straight top rod passes through the mold core to contact the plastic piece; an internal pulling block is arranged in the mold core; the internal pulling block is matched with the inclined hole of the plastic piece; the internal core-pulling mechanism is characterized in that: an inclined sliding seat is arranged on the top plate; an inclined chute is made in the inclined sliding seat; a rolling pin is arranged in the inclined chute; an inclined top rod is arranged on the rolling pin; and the inclined top rod passes through the mold core and is connected with the internal pulling block. According to the technical scheme, the internal core-pulling mechanism for the inclined hole of the injection-molded plastic piece is ingenious in idea and simple in structure, reduces the production cost without additionally applying power, and has no interference in a water path hole of the mold and no influence on the cooling effect of the mold; moreover, the internal core-pulling mechanism can be used for processing all the injection-molded plastic pieces with the inclined holes or inclined blind holes, and has wide applicability and remarkably active effect.
Description
Technical field
The present invention relates to the internal core-pulling mechanism of a kind of injection-moulded plastic spare inclined hole (tiltedly blind hole), belong to the mould of plastics field.
Background technology
Injection-moulded plastic spare (for example household electrical appliance working of plastics) all is shaped on inclined hole (tiltedly blind hole), the prior art inclined hole loose core generally all be adopt oil cylinder or spring to be used as power to drive core insert (in take out piece) directly loose core, the shortcoming of its existence is: complex structure, oil cylinder or spring trouble is installed, particularly interfere, influence the cooling effect of mould with hole, mould water route.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, easy for installation in order to overcome the shortcoming that prior art exists, and does not influence the mould water route, and utilizes the power of injection machine own, need not to put in addition power, the injection-moulded plastic spare that reduces cost inclined hole internal core-pulling mechanism.
Summary of the invention
The technical scheme of injection-moulded plastic spare inclined hole internal core-pulling mechanism of the present invention is: comprise cope match-plate pattern and lower bolster, cope match-plate pattern connects die cavity, top board and mould pin are installed on the lower bolster, on the mould pin core is installed, constitute die cavity between core and the die cavity, moulding plastics spare is arranged in the die cavity, straight push rod is installed on the top board, and straight push rod passes core and contacts with working of plastics, takes out piece in installing in the core, in take out piece and match with the working of plastics inclined hole, it is characterized in that oblique slide is installed on the described top board, tiltedly be shaped on oblique chute in the slide, tiltedly in the chute roller bolt is arranged, angle ejector rod is installed on the roller bolt, brace top pass core with in take out piece and be connected.
Injection-moulded plastic spare inclined hole internal core-pulling mechanism of the present invention, during work, at first drive core and die cavity die sinking by injection machine, top board drives the direct jack-up working of plastics of straight push rod, simultaneously, in up pushing up, top board drive angle ejector rod takes out piece, because angle ejector rod connects roller bolt down, roller bolt rolls in the oblique chute of oblique slide, and when top board drive angle ejector rod upwards pushed up, roller bolt can produce along the action of oblique chute to lower slider, the action that ejects of angle ejector rod just relatively lags behind in straight push rod like this, therefore, angle ejector rod has just produced the action of loosing core of (or to the right) downwards left with respect to inclined hole, thereby realizes loosing core of inclined hole.The technical program is skillfully constructed, and is simple in structure, utilizes the oblique sliding characteristics of oblique chute, angle ejector rod produced downwards left or to the right the action of loosing core downwards, the demoulding thereby realization is loosed core.And the power that drives angle ejector rod is the power of injection machine own, need not to put in addition power, reduces production costs, and particularly hole, mould water route is not had interference, does not influence the cooling effect of mould.The internal core-pulling mechanism of this programme can be used for all and is shaped on inclined hole or the tiltedly processing of the injection-moulded plastic spare of blind hole, and very wide of the scope of application has very significant good effect.
Injection-moulded plastic spare inclined hole internal core-pulling mechanism of the present invention, described roller bolt is installed link outward, and the link distribution connects angle ejector rod, and is easy to connect, reliable.Described oblique slide is fixed in the top board by screw, and it is firm to install.Described angle ejector rod is equipped with guide pin bushing outward, and guide pin bushing has been arranged, and reduces the friction with core.Described angle ejector rod with in take out piece and be connected by pin, it is firm to connect.
