Description
Technical field
The utility model belongs to injection molding special mechanism technical field, and the injection mold side specifically based on cam mechanism is taken out
Core apparatus.
Background technology
Plastic products are very extensive in the application of all trades and professions such as machinery, building, automobile and shipbuilding at present, and it is molded
The requirement of quality also more and more higher.Injection molding is equipped as the critical process of moulding, is played not in plastic production process
Alternative effect.Have that side is recessed and the plastic of side opening for some outer surfaces, small-sized core need to be into one with main die sinking direction during shaping
Fixed angle, before the plastic demoulding, these small-sized cores must leave shaping position using side core-pulling device.But existing side core-pulling
Injection mold structure is complicated, and maintenance is inconvenient, and manufacturing cost is higher, and the plastic cost being molded also remains high.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned deficiency, there is provided a kind of reliability is high, simple in construction, can reduce mould system
Cause this injection mold side core-pulling device.
The technical solution of the utility model is as follows：
Injection mold side core-pulling device based on cam mechanism, including cam, roller, nut, axle, connecting rod, sliding block, side spelling
Block and drag hook；The cam is fixed on top clamping plate；The roller is mounted on an axle, and is produced axially with nut limitation roller
Motion；Described connecting rod one end is fixed on sliding block, one end connecting shaft；The sliding block is arranged in the piece of side, and in side piece
Inside pumped；The side piece is fixed on moving platen；The sliding block is connected with side core；It is described
Drag hook fixing end is connected with moving platen, and hook end contacts with cam mechanism, and is moved in open mold with dynamic model part.
Slotted on rear side of above-mentioned cam, left side opening.
Above-mentioned cam left end is horizontal rail, and right-hand member is raised track.
As the further scheme of the utility model：The sliding block can make monolithic construction with side core.
As the further scheme of the utility model：The roller is required in matched moulds in the raised track of cam.
As the further scheme of the utility model：The side core-pulling device requires downward core pulling.
The utility model has following beneficial effect：The utility model is that a kind of reliability is high, easy to maintenance, can be reduced
The injection mold side core-pulling device of die manufacturing cost.Cover half part is by top clamping plate, solid plate and on top clamping plate
The parts such as cam form；Dynamic model part by Bottom clamp plate, punch-pin, punch retainer, supporting plate, side piece, drag hook, side core,
The parts composition such as sliding block and the roller that is connected with sliding block.When mould is in matched moulds state, in mold clamping force and the work of cam
Shaping position is in lower side core；During die sinking, in the presence of mould opening force, parting of the mould from dynamic model part and cover half part
Separated at face, now cover half part is motionless, and the cam being fixed on top clamping plate is also fixed, and plastic bag is on punch-pin
Retreated with dynamic model, sprue puller pulls out the sprue condensate of running gate system from runner, and side core and sliding block are while servo-actuated
Mould part move, on one side again under the self gravitation effect of side core and sliding block, force roller in cam rail from high to low
Place rolls, and starts side core-pulling.When roller movement terminates to cam horizontal track section timesharing, side core-pulling；Dynamic model part continues to move to,
After dynamic model part moves a certain distance, injector ejector pin contact push pedal, ejecting mechanism is started working, and makes push rod and sprue puller point
Plastic and gating system of material are not released from punch-pin, plastic and gating system of material are fallen from mould together, complete one
Secondary plastic knockout course.During matched moulds, in the presence of mold clamping force, roller moves in cam rail, and side core resets.This practicality
New principle is simple, improves the reliability of side core-pulling, and later period maintenance is convenient to.

Embodiment
Such scheme is described further with reference to specific embodiment.It should be understood that these embodiments are to be used to illustrate this
Utility model rather than limitation the scope of the utility model.The implementation condition that is used in embodiment it is unreceipted be usually conventional real
Condition in testing.
The injection mold side core-pulling device based on cam mechanism of the utility model embodiment shown in Fig. 1, Fig. 2 and Fig. 3, by
Drag hook 12, cam 13, roller 14, nut 15, axle 16, connecting rod 17, sliding block 18 and side piece 19 form；The cam 13 is fixed
On top clamping plate 1；The roller 14 is arranged on axle 16, and is limited roller 14 with nut 15 and produced axial movement；The company
