Description
Technical field
The present invention relates to a kind of mfg. moulding die of paper bobbin, particularly a kind of mould of making stamping semi-cylindrical.
Background technology
At present, industrial production coil paper or production volume film paper bobbin or other reels used are made by strong fibrous paper applying glue, because strong fibrous paper is wanted the manufacturing of high-quality timber, and the destruction of causing the forest reserves, unfavorable to environmental protection; Disclosed a kind of coining particle mould (CN201095153Y), this mould comprises upper die and lower die, patrix is made of fixed head and upper bolster, and counterdie is made of counterdie fixed head, die shoe and shaping mold cavity, is provided with stripper apparatus between patrix, upper mould fixed plate; This technical scheme is only suitable for making flat moulded board, if for the manufacture of columnar moulded board, can not guarantee the even thickness of blanking, a kind of stamping semi-cylindrical die of uniform blanking, become the needs of making mold pressing half reel, made the mold pressing reel to utilize mold pressing half reel.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art; a kind of stamping semi-cylindrical die is provided; utilize the wood shavings of waste materials or fiber etc. to make stamping semi-cylindrical; the recycling stamping semi-cylindrical is combined into mold pressing circle reel; paper bobbin or other reels produced as paper use; reduce the consumption of strong fibrous paper, reduce the loss to the forest reserves, protect the limited forest reserves.
The technical solution adopted in the present invention is, stamping semi-cylindrical die includes patrix and counterdie, and patrix is made of movable core rod and upper bolster; Counterdie is provided with die shoe, and die shoe is provided with the blanking die cavity, and patrix is fixedly connected with the upper hot pressboard of hot press, and counterdie is fixedly connected with the lower hot pressing board of hot press; Movable core rod is made of core rod seat and a plurality of punch insert, and the core rod seat is fixedly connected with upper bolster, and punch insert is positioned at the core rod seat, and punch insert is connected movingly with the core rod seat, is provided with Compress Spring between punch insert and upper bolster; Counterdie includes baiting control device, and baiting control device is made of dynamical element and blanking core, and the blanking core is connected with dynamical element, and dynamical element is fixed in die shoe, and the blanking core is arranged in the blanking die cavity.
the operation principle of stamping semi-cylindrical die is: utilize be installed on hot press stamping semi-cylindrical die after with applying glue wood shavings or applying glue after the fiber hot-press solidifying become semi-cylindrical shaped, during work, patrix is fixedly connected with the upper hot pressboard of hot press, and counterdie is fixedly connected with the lower hot pressing board of hot press, before blanking, the dynamical element that is fixed in die shoe is released the blanking core, make the blanking core be arranged in the blanking die cavity of die shoe, make and form a semicylindrical die cavity between blanking core and blanking die cavity, then fiber after the wood shavings after applying glue or applying glue is put into this semicylindrical die cavity, wood shavings semicircular cylinder after the applying glue of a pine of formation or the fiber semicircular cylinder after applying glue, controlling dynamical element pulls out the blanking core again, make the blanking core withdraw from the blanking die cavity, make the wood shavings semicircular cylinder of pine or the centre of fiber semicircular cylinder leave half cylindrical space, to guarantee the even density of produced wood shavings semicircular cylinder or fiber semicircular cylinder, the control hot press presses down, the punch insert of movable core rod is under the effect of the elastic force of Compress Spring, punch insert protrudes from the core rod seat, because the size of punch insert is less than wood shavings semicircular cylinder or the middle half cylindrical space size that leaves of fiber semicircular cylinder of pine, at first punch insert enters the centre of wood shavings semicircular cylinder or fiber semicircular cylinder and leaves in half cylindrical space, makes the wood shavings semicircular cylinder of pine or applying glue wood shavings material or the fiber sizing material on fiber semicircular cylinder both sides can not be forced into the centre of blanking die cavity, continuous decline along with the hot press upper hot pressboard, a plurality of punch inserts at first progressively compress applying glue wood shavings material or the fiber sizing material of blanking cavity bottom, then applying glue wood shavings material or the fiber sizing material on blanking die cavity both sides are compressed, then compressed to the core rod seat of patrix applying glue wood shavings material or the fiber sizing material to the blanking die cavity top, when the density of compressed applying glue wood shavings material or fiber sizing material constantly increases to setting value, the elastic force that punch insert overcomes Compress Spring constantly is pressed in the core rod seat, make a plurality of punch inserts form the arc surface that radius is identical with the lower surface of core rod seat, this moment patrix and counterdie matched moulds, wood shavings semicircular cylinder or fiber semicircular cylinder enter thermal curing time, wood shavings semicircular cylinder or fiber semicircular cylinder are compressed in heat cure moulding between the semicircle cambered surface of the semicircle cambered surface of the identical movable core rod of this radius and blanking die cavity, thermal curing time arrives, and the hot press upper hot pressboard drives patrix and rises, and punch insert resets under the elastic force effect of Compress Spring and stretches out in the core rod seat, the stripper apparatus of counterdie is the stamping semi-cylindrical jack-up of heat cure moulding, and stamping semi-cylindrical is taken out, and dynamical element is pushed out of the blanking core in die shoe blanking die cavity, then prepares next part stamping semi-cylindrical of blanking hot pressing.
The beneficial effect of the invention is: paper bobbin or other reels utilize stamping semi-cylindrical to combine, stamping semi-cylindrical utilizes the materials such as wood residues wood shavings or bagasse fibre and mixed with resin to form through high temperature and high-pressure curing, reduce the destruction to the forest reserves, be conducive to environmental protection; The patrix of stamping semi-cylindrical die is provided with a plurality of flexible punch inserts, and the punch insert of protrusion progressively presses down, and the problem that when having solved hot pressing, applying glue wood shavings material or fiber sizing material move has than uniform density hot pressing stamping semi-cylindrical out.
