Abstract
A kind of stop device of injection mould side core-drawing mechanism of slanting sliding block, belongs to injection mold special mechanism technical field, for solve the problem of side core-drawing mechanism of slanting sliding block die sinking carry out at the very start side core-pulling so as to cause plastic damage or be trapped in cover half and can not take out.Device is made of angled-lift splits, die sleeve, dynamic mould core fixed plate, push rod, dynamic mould core support plate, dynamic mould core, fixed mold, fixed mold fixed plate, fixed mold support plate, spring and straight pin.Just during die sinking, straight pin is to left movement under the action of spring force, and straight pin withstands angled-lift splits always, and therefore angled-lift splits will not generate relative motion with die sleeve, and fixed mold is forced first to depart from from plastic, and plastic is allowed to stay on dynamic mould core.Continue to mold, when angled-lift splits and straight pin disengage, angled-lift splits just under the promotion of push rod in die sleeve along guide runner starting side parting, until plastic demoulds completely, therefore improve the quality of angled-lift splits side core-pulling injection molding plastic.
Description
Technical field
The utility model belongs to injection mold special mechanism technical field, is specifically a kind of injection mould angled-lift splits side core-pulling machine
The stop device of structure.
Background technology
When the side of plastic is recessed shallower, required Core-pulling distance is little, if but side it is recessed shaping area it is larger when, required pumping
Core power is also larger, needs to select the angled-lift splits core-pulling mechanism of advantage of lower cost to carry out side parting with core pulling to improve product at this time
Price competitiveness.Angled-lift splits is generally arranged at dynamic model one side, and plastic is required to be more than to cover half the package power of dynamic model part
Partial package power.But sometimes because the special construction of plastic, the package power of cover half part is more than in dynamic model part or non-phase
Under, side core-drawing mechanism of slanting sliding block traditional at this time will die sinking carry out side core-pulling at the very start, this will cause plastic damage or
Being trapped in cover half can not take out.
The content of the invention

Push rod, dynamic mould core support plate, dynamic mould core, fixed mold, fixed mold fixed plate, fixed mold support plate, spring and circle
Pin；The angled-lift splits is mounted in die sleeve；The spring is mounted in fixed mold support plate；The straight pin connects with spring
It connects；The dynamic mould core is fixed between dynamic mould core fixed plate and dynamic model support plate；The fixed mold relies on fixed mold
Fixed plate is fixed with the installation of fixed mold support plate；The die sleeve is connected with dynamic mould core fixed plate；The push rod passes through dynamic model
Core support plate and dynamic mould core fixed plate are contacted with angled-lift splits.
The coaxial stepped hole in above-mentioned fixed mold fixed plate straight pin installation place level of processing direction.
The angle of inclination of above-mentioned angled-lift splits is less than 35 °.
As the further scheme of the utility model：The guide runner of the die sleeve is monoblock type guide runner.
As the further scheme of the utility model：The spring is in compressive state in molding.
Preferably, the side core-drawing mechanism of slanting sliding block is to side core-pulling outside plastic and undercut.
The utility model has following beneficial effect：The utility model is a kind of simple in structure, easy to use, can be improved
The stop device of the injection mould side core-drawing mechanism of slanting sliding block of die side core pulling action reliability and plastic part quality.It is closed when mold is in
During mould state, the spring between straight pin and fixed mold support plate is in compressive state；During die sinking, in mould opening force
Under effect, angled-lift splits, die sleeve, dynamic mould core fixed plate, push rod, dynamic mould core support plate and dynamic mould core are transported to the left simultaneously
It is dynamic, while spring starts to depart from constraint, straight pin is under the action of spring force to left movement；In the process, straight pin begins
Angled-lift splits is withstood eventually, and therefore angled-lift splits will not generate relative motion with die sleeve, and fixed mold is forced first to depart from from plastic, allow
Plastic is stayed on dynamic mould core；Continue to mold, when angled-lift splits and straight pin disengage, angled-lift splits just under the promotion of push rod
Along guide runner starting side parting in die sleeve, until plastic demoulds completely.The utility model is solved in side core-drawing mechanism of slanting sliding block
Middle angled-lift splits is initially possible to generate relative motion with dynamic model in die sinking, so that plastic is trapped in cover half and can not take out
The problem of, improve the quality of angled-lift splits side core-pulling Injection Mold Formation plastic.

Specific embodiment
Said program is described further with reference to specific embodiment.It should be understood that these embodiments are for illustrating this
Utility model rather than limitation the scope of the utility model.What the implementation condition used in embodiment was not specified is usually conventional real
Condition in testing.
The stop device of Fig. 1 and a kind of injection mould side core-drawing mechanism of slanting sliding block of the utility model embodiment shown in Fig. 2,
Including angled-lift splits 2, die sleeve 1, dynamic mould core fixed plate 3, push rod 4, dynamic mould core support plate 5, dynamic mould core 6, fixed mold 7,
Fixed mold fixed plate 8, fixed mold support plate 9, spring 10 and straight pin 11；The angled-lift splits 2 is mounted in die sleeve 1；Institute
Spring 10 is stated in fixed mold support plate 9；The straight pin 11 is connected with spring 10；The dynamic mould core 6 is fixed on
Between dynamic mould core fixed plate 3 and dynamic model support plate 5；The fixed mold 7 is by fixed mold fixed plate 8 and fixed mold branch
The installation of fagging 9 is fixed；The die sleeve 1 is connected with dynamic mould core fixed plate 3；The push rod 4 is through dynamic mould core support plate 5 and moves
Mould core fixing plate 3 is contacted with angled-lift splits 2.
As further embodiment：The coaxial rank in the 8 straight pin installation place level of processing direction of fixed mold fixed plate
Terraced hole；The angle of inclination of the angled-lift splits 2 is less than 35 °；The guide runner of the die sleeve 1 is monoblock type guide runner；The spring 10
Compressive state is in molding；The side core-drawing mechanism of slanting sliding block is to side core-pulling outside plastic and undercut.
The utility model is a kind of simple in structure, easy to use, can improve die side core pulling action reliability and plastic matter
The stop device of the injection mould side core-drawing mechanism of slanting sliding block of amount.When mold is in molding state, mounted on straight pin 11 and determine
Spring 10 between model core support plate 9 is in compressive state；During die sinking, under the action of mould opening force, angled-lift splits 2, die sleeve 1,
Dynamic mould core fixed plate 3, push rod 4, dynamic mould core support plate 5 and dynamic mould core 6 move to the left simultaneously, while spring 10 starts
Depart from constraint, straight pin 11 is under the action of 10 elastic force of spring to left movement；In the process, straight pin 11 withstands oblique cunning always
Block 2, therefore angled-lift splits 2 will not generate relative motion with die sleeve 1, and fixed mold 7 is forced first to depart from from plastic 12, allow plastic
12 stay on dynamic mould core 6；Continue to mold, when angled-lift splits 2 and straight pin 11 disengage, angled-lift splits 2 is just in the promotion of push rod 4
Under in die sleeve 1 along guide runner starting side parting, until plastic 12 demoulds completely.The utility model is solved to be taken out in angled-lift splits side
Angled-lift splits is initially possible to generate relative motion with dynamic model in die sinking in core mechanism, so that plastic is trapped in cover half and nothing
The problem of method is taken out improves the quality of angled-lift splits side core-pulling Injection Mold Formation plastic.
