Description
Technical field
The present invention relates to a kind of mold work mechanism, more specifically, it relates to which a kind of sliding block two-part core pulling is stripped by force
Mechanism.
Background technology
All there is the tubular body with back-off structure, such as flexible pipe connection-peg and some kinds of buckle head on many injecting products
Deng, take melting material solidify straight forming back-off structure processing mode it is ideal, the back-off structure so generated is smoothly continuous,
Uniformity is good, structural integrity, and intensity is high, but it is due to mould when mould is opened to implement a maximum problem of such a processing method
The core bore step of upper generation tubular body back-off structure is engaged with the sizing material formation of solidification, and is typically only made during mould opening simple
Rectilinear movement, therefore the tubular body of injecting products can not depart from from the core bore on mould, and whole injecting products can not be smooth
The demoulding.Therefore, the existing tubular body processing with back-off structure is generally all to use double of subdivision of tubular body, pass through two respectively
The method of half mold forming is completed.But half module molding mode can cause spue line to fall on tubular body side face, tubular body side face is put down
Slippery, continuity are all poor, and if tubulose body bias on injecting products, will give the choosing of injecting products matched moulds line position
Take and mould is moved, the distribution of cover half brings very big difficulty.Publication No. CN205870956U utility model was January 11 in 2017
Disclose a kind of strong demoulding lamps structure of casing back-off structure day, the casing includes the multiple fixed columns set along edge, often
The top of one fixed column has the back-off post that two back spans are set, and the end of the back-off post is barb-like back-off portion, and this is strong
Demoulding lamps structure includes two first mold inserts for being placed in fixed column both sides to be formed, and is placed in the second of fixed top end to be formed
Mold insert；Every one first mold insert has the cavity structure that the fixation post shapes with corresponding back-off post and respective side match；This
Two mold inserts include the core part that is connected to the connecting portion on corresponding mould bases panel and can be inserted between two back-off posts to be formed.Should
The strong demoulding lamps structure for the casing back-off structure that utility model is provided need not simplify mould knot using complicated side core drawing structure
Structure, reduces die cost, while also improving productivity ratio.But the utility model is only capable of completing point of the first mold insert, the second mold insert
From action, condition is provided for the demoulding of fixed column on injecting products, but product the final demoulding need again it is complete by other mechanisms
Into mould overall structure is relative complex.
The content of the invention
Using the mould of normal working practices, tubular body of the processing mode straight forming with back-off structure is solidified using melting material
When, tubular body is difficult to depart from from the core bore on mould, and whole injecting products can not be smoothly stripped, to overcome this defect, this
Invention makes the tubular body with back-off structure smoothly depart from from the core bore of mould there is provided a kind of, so that injecting products are smooth
The strong mould emptier of sliding block two-part core pulling of the demoulding.
The technical scheme is that：A kind of strong mould emptier of sliding block two-part core pulling, in the lower template of mould, this
The strong mould emptier of sliding block two-part core pulling includes oil cylinder, slider-actuated component, big sliding block, small slide block, small slide block pin and small cunning
Block stroke keeper, the piston rod of oil cylinder is connected with slider-actuated component, and slider-actuated component is connected with small slide block, small slide block with
Big sliding block is slidably connected, and is connected between small slide block and big sliding block by small slide block stroke positioning component, big sliding block and lower template
Be slidably connected, big sliding block be provided with back-off structure provided with internal diameter expansion in the core bore that connect with the core rod of lower template, core bore into
Type annular chamber, small slide block pin is connected on small slide block and through the core bore of big sliding block, and small slide block pin is coaxial and small with core bore
Sliding block pin external diameter, which is less than in core bore internal diameter, lower template, is fixedly provided with the travel switch for detecting big sliding block shift motion.Complete
After the processes such as mould matched moulds, injection, pressurize, cooling, curing molding, oil cylinder starts under control system control, carries out two ranks
The core pulling operation of section, first stage, cylinder piston rod promotes small slide block motion, pulls small slide block pin to remove cured tubulose
Body, relative between large and small sliding block around here to slide, big sliding block is blocked and remained stationary as by molded product back-off structure；Second stage,
When the relative displacement that cylinder piston rod continues to press between small slide block, large and small sliding block is reached the limit of, small slide block passes through small slide block stroke
Positioning component transmits pulling force to big sliding block, and big sliding block is moved with small slide block, because small slide block pin has been moved out tubular body, core
The space of tubular body contraction distortion is generated in hole, therefore during big sliding block movement, the back-off structure of tubular body is extruded by core bore wall
Shrink, can release and be molded being engaged for annular chamber with back-off structure, tubular body can be extracted out from core bore, hereafter be may continue to execution and opened
The processes such as mould, the demoulding., can with same oil cylinder when there are the injecting products of the tubular body with back-off structure using present invention production
This two sections of processes are extracted out with injecting products tubular body, reduce mold mechanism to perform small slide block pin extraction during complete core pulling
Configuration, simplifies mould structure, reduces mould volume.
