Description
Technical field
The present invention relates to a kind of threeway and mould iron clad pipe fitting mold fastener fuse resetting-mechanism, belong to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, plastic pipe for example particularly adopts the tee pipe fitting of PE raw material injection mo(u)lding; For the conservation cost, but the compressive strength of raising pipe fitting is effectively controlled the pipe fitting deflection; In tee pipe fitting, install brandreth (part) additional, i.e. the iron clad pipe fitting is moulded in threeway.Existing threeway is moulded the iron clad pipe fitting and when injection moulding, at first a straight-through fastener is inserted in outside one in the straight-through fuse; Again brandreth is inserted in outside this fastener; Then another straight-through fastener is embedded outside the other end of straight-through fuse; Brandreth is fixed; Then the threeway fastener is inserted in outside the threeway fuse; The threeway fuse is driven by oil cylinder, is embedded into the threeway fastener in the threeway of brandreth, last mould mold-closing injection.During the demoulding, at first drive the threeway fuse by oil cylinder and loose core, mould die sinking is again moulded the iron clad pipe fitting by the mould ejecting mechanism with the threeway of injection mo(u)lding and is ejected outside the mould from straight-through fuse.The shortcoming of its existence is: because the threeway fuse is to be driven by oil cylinder, in the time of in the threeway that is embedded into brandreth with the threeway fastener, brandreth is collided easy displacement, distortion, causes pipe fitting of poor quality, even scraps.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art; A kind of employing card off-square formula automatically is provided; The threeway fuse is driven by oil cylinder looses core; When resetting and oil cylinder disengage; Manually promote the threeway fuse and reset, avoid making the threeway of its displacement, distortion mould iron clad pipe fitting mold fastener fuse resetting-mechanism with the brandreth collision.
The technical scheme that iron clad pipe fitting mold fastener fuse resetting-mechanism is moulded in threeway of the present invention is: comprise injection mold; Described injection mold comprises compound plate and following compound plate; Last compound plate connects the die cavity frame down; Die cavity is installed in the die cavity frame; Be equipped with the straight-through fuse of die cavity in the die cavity; Mould pin and top board are installed on the following compound plate; Push rod is installed on the top board; The core frame is installed on the mould pin; Core is installed in the core frame; Be equipped with the straight-through fuse of core on the core; The straight-through fuse of core matches with the straight-through fuse of die cavity; Side at the core frame is installed outer slide; Outer slide connects the threeway fuse; The threeway fuse is with triplet card spare outward; The threeway fastener matches with the threeway of brandreth; On a side outer wall of core frame, cylinder bracket is installed; Oil cylinder is installed on the cylinder bracket; The piston rod of oil cylinder connects outer slide; And the drive outer slide is sliding outward; It is characterized in that being equipped with between described piston rod and the outer slide automatic card off line structure; Described automatic card off line structure is included in and installs block tongue and following block tongue in the outer slide; On; On following block tongue has respectively; The lower compression spring; On; Constitute bayonet socket between the following block tongue; Last; The head of following block tongue is shaped on block tongue inclined-plane and following block tongue inclined-plane respectively; The head of said piston rod is shaped on draw-in groove and trapezoidal faces; Bayonet socket matches with the draw-in groove of piston rod; Trapezoidal faces and last block tongue inclined-plane are tangent with following block tongue inclined-plane; On the cylinder body of said oil cylinder, be equipped with upper plunger and lower plunger; On; The head of lower plunger is shaped on upper plunger inclined-plane and lower plunger inclined-plane respectively, and upper plunger inclined-plane and lower plunger inclined-plane and last block tongue inclined-plane are tangent with following block tongue inclined-plane.
Iron clad pipe fitting mold fastener fuse resetting-mechanism is moulded in threeway of the present invention; During the demoulding; The piston rod of oil cylinder stretches out; The trapezoidal faces of piston rod head and last block tongue inclined-plane are tangent with following block tongue inclined-plane; Strut block tongue and following block tongue; The draw-in groove of piston rod is snapped in the bayonet socket between block tongue and the following block tongue; Piston rod and outer slide successful connection; Drive outer slide and threeway fuse and loose core, when outer slide and the extraction of threeway fuse, upper plunger inclined-plane and lower plunger inclined-plane on the cylinder block of last block tongue inclined-plane and following block tongue inclined-plane and installation are tangent; Strut block tongue and following block tongue again; Piston rod is deviate from from bayonet socket, and then die sinking is by the pipe fitting ejection device of push rod with injection mo(u)lding; After by manual work fastener and brandreth being installed then; Manually promote outer slide again and the threeway fuse resets, last mould mold-closing injection, so circulation.This programme adopts card off-square formula automatically, the threeway fuse is driven by oil cylinder loose core, and disengages with oil cylinder when resetting, and manually promotes the threeway fuse and resets, and avoids making its displacement, distortion with the brandreth collision, guarantees that pipe fitting injection moulding quality is good, the compressive strength height.
Iron clad pipe fitting mold fastener fuse resetting-mechanism is moulded in threeway of the present invention, is equipped with fixed head on the described cylinder block, and upper plunger and lower plunger are installed on the fixed head, and fixed head has been arranged, and upper plunger and lower plunger are easy for installation, and be firm.
