Design principle of the present utility model is:
The utility model has overcome metal cone former problem of difficult processing, changes into the formpiston of making the mould of plastics piece, cooperates attached Mould Machining to go out the mould of plastics piece by this formpiston.Because the good relatively processing of formpiston of processing plastic mould piece, therefore production cost is lower more than 10 times than the metal die of producing similar shape, its processing technology is also simple relatively, as long as the installing hole precision of location and installation plate meets the requirements, just can form with a plurality of mould of plastics pieces that bore is variable, the mould of shape variable.
Described mould of plastics piece is to require to design the cone formpiston according to reality, in a mould of plastics piece, set what single awls according to the size decision of cone, the mould of plastics piece is plastic injection-moulded, evenly, smooth surface, its symmetry that is evenly distributed of back is installed, stressed even when the demoulding, be convenient to the demoulding; The mould of plastics piece has pliability preferably than metal die again, and easy damaged cone top not when the demoulding makes sharper that cone does, and molding effect is better.And owing to the weight of mould of plastics than metal die reduces relatively, the labour intensity when having reduced to use.
The mould of plastics piece can be made into circle, ellipse or regular polygon; Single cone-shaped can be circular cone, round platform, orthopyramid or positive terrace with edge.Entire die is made up of a plurality of mould of plastics pieces, and mould caliber size and shape can be made according to the radiant body base shape, and the big redundance of existence can cut removal, and little redundance can solve by filling.When not demoulding phenomenon occurring, metal pattern has the possibility of all scrapping, and mould of plastics only needs and will can continue to use because of the mould of plastics piece replacing that the not demoulding damages.
The purposes of the location and installation plate of described mould of plastics is accurately to install and fix the mould of plastics piece, on metal base plate, precision has been arranged mould of plastics piece location and installation hole exactly, each location and installation hole all with the mould of plastics piece on the fixed installation post accurately cooperate, guarantee that the mould of plastics piece is indeformable not stress.The location and installation buttress decides its size and shape according to the entire die size, above the mould of plastics piece is pieced together and is installed in.The installing hole that the location and installation plate makes a circle outward and is provided with is used to install the metal frame that anti-cast logistics is lost.
The both anti-cast of described metal frame logistics is lost, and determines the shape of entire die actinal surface again, and the entire die actinal surface can be for square, circular or oval or the like.The mould of plastics piece periphery of described metal frame and adjacency closely cooperates, and the slit sticks with glue and connects.Metal frame exceeds certain distance than mould of plastics piece actinal surface, and the one, prevent to pour into a mould logistics and lose, the 2nd, the minimum thickness of cast absorbing material on the decision radiant body.
