Abstract
The utility model discloses an injection mold back -off mechanism of loosing core, including bullet piece, spring, spacing ripples pearl, slider, ejector pin, bullet piece and spring all install in the fixed die plate and the top at the bullet piece is leaned on on the spring top, the top at the slider is leaned on on the bottom top of bullet piece, the slider slip at the movable mould inboard, be equipped with a plurality of constant head tanks on the outer wall of slider, in fixed mounting leaned on the constant head tank at the slider outer wall on the spacing ripples pearl of movable mould inboard inner top, an ejector pin hole of running through the total length was seted up at the middle part of slider, the upper portion of ejector pin can penetrate and wear out the ejector pin hole of this slider. Because the utility model discloses during the die sinking, the bullet piece is the roof pressure slider under the effect of spring force, make the slider activity break away from the knot position of product, then the ejector pin control slide in upright upwards the direction is moved moves to deviate from the ejecting product of back -off, solved like this owing to push up too xiao yi fracture to one side and block dead problem, improved mould utility life -span and product production efficiency simultaneously.
Description
Technical field
This utility model is related to a kind of injection mold, more particularly to a kind of injection mold back-off core-pulling mechanism.
Background technology
Plastics injection mould is the instrument producing plastic, and application is widely.In plastic injection mo(u)lding, by
There is indent in the inside of some plastics, need to carry out side core-pulling, the core-pulling mechanism commonly used is required for greatly the portions such as Angle Pin
Part, structure is complex.
Content of the invention
The purpose of this utility model is the injection mold back-off core-pulling mechanism providing a kind of structure simple, easy for installation.
For achieving the above object, technical solution of the present utility model is：
This utility model is a kind of injection mold back-off core-pulling mechanism, including bullet block, spring, spacing ripple pearl, slide block, top
Bar；Described bullet block and spring are all arranged in solid plate and spring acts against the top of bullet block, and the bottom of bullet block acts against cunning
The top of block；Described slide block slips in moving platen, and the outer wall of slide block is provided with multiple locating slots, is fixedly mounted on moving platen
Interior spacing ripple pearl the inner acts against in the locating slot of slide block outer wall, and the middle part of slide block opens up a jogger hole running through total length,
The top of push rod can be threaded in and out the jogger hole of this slide block.
This utility model also includes guide pin bushing, and push rod activity is located in guide pin bushing.
After such scheme, because this utility model includes bullet block, spring, spacing ripple pearl, slide block, push rod, during die sinking,
Bullet block top pressure slide block under spring force, makes slide block activity depart from the button bit of product, then, push rod is in upright direction
Control slide block motion in motion, and deviate from back-off ejecting product, so solve due to the too little easy fracture of oblique top and stuck asking
Topic, processing is easier for installation, improves mold use life-span and production efficiency simultaneously.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Brief description
Fig. 1 is this utility model axonometric drawing；
Fig. 2 is exemplary application map of the present utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, this utility model is a kind of injection mold back-off core-pulling mechanism, including bullet block 1, spring 2, limit
Position ripple pearl 3, slide block 4, push rod 5, guide pin bushing 6.
Described bullet block 1 and spring 2 are all arranged in solid plate 10 and spring 2 acts against the top of bullet block 1, bullet block 1
Bottom acts against the top of slide block 4.
Described slide block 4 slips in moving platen 20, and the outer wall of slide block 4 is provided with multiple locating slots 41, is fixedly mounted on
Spacing ripple pearl 3 the inner in moving platen 20 acts against in the locating slot 41 of slide block 4 outer wall, plays the effect limiting slide block 4 movement；
The middle part of slide block 4 opens up a jogger hole 42 running through total length, and the top of push rod 5 can be threaded in and out the jogger hole of this slide block 4
42, the middle part activity of push rod 5 is located in guide pin bushing 6, and guide pin bushing 6 is arranged in dynamic model so that the ejection action of push rod 5 is more suitable
Smooth and stable.
Operating principle of the present utility model：
Push rod 5 ejects, stopping action after slide block 4 mobile 6.5mm under the control of spacing ripple pearl 3, and at this moment slide block 4 is past
Intermediate active 2.3mm, has completely disengaged from buckle.Push rod 5 passes through ￠ 8.2 via on slide block 4, and product ejects.
During mould matched moulds, push rod 5 first retreats, and bullet block 1 flicks 4mm it is ensured that slide block 4 first resets under spring 2 effect.
The above, only this utility model preferred embodiment, therefore this utility model enforcement can not be limited with this
Scope, the equivalence changes made according to this utility model claim and description and modification, all should still belong to this reality
In the range of being covered with new patent.
