Abstract
The invention discloses a die for plastic extrusion and molding of a building external corner plastic formwork, a lower formwork is fixedly arranged on the bottom formwork of the die, an upper formwork is arranged above the lower formwork, the working face of the lower formwork is in right-angled depression, the working face of the upper formwork is in right-angled protuberance, a depressed bar groove is arranged on the lower formwork, the lower formwork and the upper formwork form an external corner cavity, racks are arranged on two sides of the bottom formwork, a plurality of bottom formworks constitute a crawler by using connecting parts, the upper formwork is fixed and stationary, the lower formwork moves along with the crawler formed by the bottom formworks, an ejector pin is arranged on each bottom formwork, a spray nozzle is arranged on the upper formwork, and the spray nozzle is in butt joint with a spray nozzle of a plastic extruder. The die can effectively use the plastic extruder to continuously produce the building external corner plastic formwork with transverse and vertical cross bars or special-shaped bars, thereby greatly improving the production rate, improving the production quality, being capable of continuously producing the plastic formwork with a variety of bar shapes, and solving the bid and difficult problem that the plastic extruder can not continuously produce the plastic formwork with the cross bars.
Description
Technical field
The present invention relates to the mould of plastic building template, more specifically relate to a kind of mould of plastic extrusion and molding of building external corner plastic formwork.
Background technology
Current, the building external corner template is based on timber, woodwork plate, metal form, and its timber, woodwork plate are lacked service life, and the wasting of resources is big, not beneficial promotion; Metal form demoulding difficulty, yielding, service life is shorter, and bigger to metals resources waste consumption, country does not advocate.Particularly the building external corner template remains at present and adopts the special metal form of making or special carpenter's template of making.A kind of template that the building plastic template is in recent years to be risen, it is made of plastics, and it is longer to have service life, and advantages of higher is recycled in the easily demoulding.The applicant has applied for " external corner plastic formwork for building " patent by name on October 6th, 2008, the patent No. is 200820100161.8, notification number is CN201276838, and still, external corner plastic formwork for building at that time adopts one processes of injection mo(u)lding.As, the patent No. is ZL 200720025599.X, Granted publication CN 201077134Y, Granted publication day is on June 25th, 2008, name is called " building plastic formwork mould " disclosed technical scheme, this mould production has the plastic formwork of muscle, is matched moulds up and down, the production that can only lean on one one of injection machine.In order to produce plastic formwork continuously, the Japanese publication people applied for " the rib plastic formwork extrusion forming device is arranged " patent by name again Mays 25 in 2010, and application number is 201010181880.9.But the building external corner plastic formwork does not have special continuous production mould at present, for this reason, remains to be explored the mould of special plastic extrusion and molding of building external corner plastic formwork.
Summary of the invention
Purpose of the present invention: the mould that a kind of plastic extrusion and molding of building external corner plastic formwork is provided.
Technical scheme of the present invention is:
A kind of mould of plastic extrusion and molding of building external corner plastic formwork, it is characterized in that, on end template, be fixed with lower bolster, above lower bolster, be provided with cope match-plate pattern, the working face of lower bolster is perpendicular to the sag, the working face of cope match-plate pattern is perpendicular to the convex, be provided with the muscle groove of depression on lower bolster, lower bolster and cope match-plate pattern form the external corner die cavity, are provided with tooth bar on the both sides of end template, the polylith end template is formed Track Type with connector, cope match-plate pattern maintains static, and the Track Type motion that lower bolster is formed with end template is provided with thimble on end template, be provided with spout on cope match-plate pattern, spout docks with the nozzle of extruding machine.
The described muscle groove that is provided with depression on lower bolster is vertical muscle groove and horizontal bar groove.
Described both sides at lower bolster are provided with the mould limit.
The mould of plastic extrusion and molding of building external corner plastic formwork of the present invention in use, need to connect into Track Type with the identical end template hinge of polylith, available two polygonal support wheels support crawler belt, the width of every end template equals the length of side of the regular polygon supporting surface of support wheel, and the thimble on the end template is crossed in the groove logical moving at the thimble of support wheel.Both sides at end template are provided with tooth bar, gear drive tooth bar with rotation, end template is moved along same direction, the external corner plastic formwork that drives extrusion moulding is walked out cope match-plate pattern, thimble is under the promotion of jacking block, move upward, the external corner plastics mould that ejects moulding withdraws from the muscle groove that caves on the lower bolster, finishes the demoulding.The mould of this Track Type is too heavy, can establish the support roller supporting mould, also can drive the end template motion in addition with the rotation of power drive support wheel.Mould of the present invention can be produced the external corner plastic formwork of multiple muscle shape continuously, can cut out the building external corner plastic formwork into different length specifications as required.
Beneficial effect of the present invention: the mould of plastic extrusion and molding of building external corner plastic formwork of the present invention, use extruding machine to produce the building external corner plastic formwork that has horizontal, vertical cross bar or special-shaped muscle continuously effectively, improved the speed of production that muscle building external corner plastic formwork is arranged greatly, improved the quality of production that muscle building external corner plastic formwork is arranged, realize the demoulding after having made muscle building external corner plastic formwork extrusion moulding effectively, can produce the plastic formwork of multiple muscle shape continuously, solve the hard nut to crack that extruding machine can not be produced the cross bar plastic formwork continuously.
