Description

Oblique top touches the product of piercing and takes out the mold mechanism of button bit
Technical field
It is that oblique top touches the product of piercing the present invention relates to metal die-casting mold and plastic injection mould With the mold mechanism for taking out button bit.
Background technology
Die cast metal part and plastic injection part carry back-off in dynamic model side and cover half side Mold mechanism, prior art is in the thimble fixed plate and thimble backing plate of dynamic model side Set and angled-lift splits is set on slide, slide, angled-lift splits connection thimble, when mould is opened Thimble is driven to eject product by thimble fixed plate and thimble backing plate, while thimble is to one Slideslip extracts back-off position out, and the back-off of cover half leads to due to being limited by mold mechanism The depth of back-off position can only often be reduced, then by forced stripper mechanism, directly deviate from cover half one The back-off position of side, therefore product easily occurs breaking button bit, causes product unqualified.And it is right Require high product in some sizes, the depth of back-off position can not reduce, at this moment frequently with Mechanism be by be molded back-off position part together with outside product launch mode, then outside mould Product and forming part are separated by hand, after Separation Product, then by zero will be molded by hand Part, which is put into mould, carries out moulding by casting next time.So result in low production efficiency, work People's labor intensity is big, it is important that when workman is put into forming part into mould, workman's Personal safety cannot be ensured.In order to overcome the shortcomings of existing mold, spy is provided as next Mold mechanism is planted to solve the above problems.
The content of the invention
The present invention is to provide oblique top and touches the product of piercing and take out the mold mechanism of button bit.It is so Realize:After product molding, dynamic model part is in injector or the dynamic action of die casting machine Moved after lower, mould is opened from moving platen (155) and solid plate (185) touching position, Due to separating for moving platen (155) and solid plate (185), in being mounted in cover half one The fixed mould lifter (65) of side loses pressure, because fixed mould lifter (65) loses pressure, Pressure is lost in the spring (55) for being mounted in fixed mould lifter (65) rear to upspring promotion Fixed mould lifter (65) is together moved along slide guide hole (195) with product b to dynamic model direction, Fixed mould lifter (65) drives stop screw (215) also to be moved to dynamic model direction simultaneously, Fixed mould lifter (65) to dynamic model direction while moving along slide guide hole (195) Incline direction moves laterally action to die inside direction, then fixed mould lifter (65) Extracted out at product b back-off position e.When stop screw (215) and pressing plate (205) When colliding, pressing plate (205) is spacing to stop screw (215), then stop screw (215) Pulling fixed mould lifter (65) stops the movement to dynamic model direction.And injector or die casting machine Continue to move behind driven mold dynamic model part, when die sinking is away from solidifying more than product b and running gate system Material it is total it is high after, the stopping of dynamic model part action, now, injector or die casting machine push rod are pushed away Dynamic thimble backing plate (145) drives the slide (175) being arranged in thimble fixed plate (105) Promote dynamic model oblique top (75) and thimble (85) by product b from moving platen (165) Outside middle launch mode.Oblique top touches the product of piercing and takes out the mold mechanism of button bit, and its advantage is: By setting fixed mould lifter, stop screw, pressing plate and spring in the side of cover half one, make product Back-off position positioned at the side of cover half one smoothly completes core pulling, and the quality of product has been effectively ensured, Position is worn provided with touching in dynamic model side simultaneously, and it is identical with the thickness of product to touch the depth for wearing position, by Touch and wear position promotion fixed mould lifter matched moulds reset, therefore it is simple in construction, fixed mould lifter resets Accurately.In addition, stop screw and pressing plate are located in hole, the thickness of cover half can be reduced, from And reduce molding cost.Oblique top touches the product of piercing and takes out the mold mechanism of button bit, solves contracting Small back-off bit depth, using forced stripper mechanism, directly deviates from the back-off position of cover half side, system Product occur breaking button bit, cause the underproof problem of product.Solve forming part and Product is together deviate from outside mould, by manual Separation Product and forming part, Gong Renlao outside mould Fatigue resistance is big, the problem of low production efficiency.Workman's installation forming part is solved in mould When, the problem of safety of workers cannot be ensured.Oblique top touches the product of piercing and takes out the mould of button bit Mechanism, it is characterized in that:It include dynamic model and cover half, its cover half by:Centring ring (5), Top clamping plate
