Abstract
The invention discloses a multi-layer composite co-extrusion mold of a soft PVC (polyvinyl chloride) stair anti-skid board. The multi-layer composite co-extrusion mold of the soft PVC stair anti-skid board comprises a die I, a die II, a bus board, a transition board and a die body, wherein the die II is provided with a subchannel I which comprises a material inlet of the subchannel I and three branch channels; the bus board is provided with a subchannel II which is provided with a material inlet of the subchannel II; the transition board is provided with a transition board channel I, as well as a transition board channel II and two symmetrical transition board side channels; the die body is provided with a main material inlet; the die I, the die II, the bus board and the transition board are sequentially connected through screws II; the transition board and the die body are connected through a screw I; the subchannel II increases gradually from top to bottom; and the transition board channel II decreases gradually from left to right. The multi-layer composite co-extrusion mold of the soft PVC stair anti-skid board provided by the invention is simple in structure, has reasonable channels, and can perform multi-layer material co-extrusion and composition; fluids have good fluidity in plastic media; and the multi-layer composite co-extrusion mold is low in cost and long in service life.
Description
Technical field
The present invention relates to mould of plastics, particularly flexible PVC stair limited slip plate MULTILAYER COMPOSITE co-extruding mould.
Background technology
What existing flexible PVC stair limited slip plate adopted is single layer structure, the flexible PVC stair limited slip plate of this individual layer is if all adopt the material of better performances to make, cost height then, cost is relatively low, the material of poor-performing is made if all adopt, though can reduce cost, but not wear-resisting, the life-span is low, the use cost height.In addition, because the stair limited slip plate is used for staircase, the flexible PVC stair limited slip plate of this individual layer is because of no warning mark, so security performance is relatively poor.
Summary of the invention
Purpose of the present invention just provide a kind of compact conformation, runner rationally, can carry out that multilayer material coextru-lamination, plastic liquid good fluidity, cost are low, the flexible PVC stair limited slip plate MULTILAYER COMPOSITE co-extruding mould of long service life.
For achieving the above object, the present invention includes mouthful mould one, mouth mould two, cylinder manifold, rebound and die body, described mouthful of mould two is provided with runner one, described runner one is provided with runner one charging aperture and three branch flow passages, described cylinder manifold is provided with runner two, described runner two is provided with runner two charging apertures, described rebound is provided with rebound runner I, the rebound side runner of rebound runner II and two symmetries, described die body is provided with main charging aperture, described mouthful of mould one, mouth mould two, cylinder manifold is connected by screw two successively with rebound, and described rebound is connected by screw one with die body; Described runner two increases from top to bottom gradually; Described rebound runner II reduces from left to right gradually.
The present invention is owing to be provided with runner two at cylinder manifold, and runner two increases from top to bottom gradually, but coextru-lamination goes out second layer material, and plastic liquid flows evenly; Owing to be provided with runner one at mouth mould two, runner one is provided with runner one charging aperture and three branch flow passages again, but coextru-lamination goes out trilaminate material, can form the strip plastic layer of three distinctnesses, can play U.S. decorations and warning function; In addition, owing to the rebound side runner that is provided with rebound runner I, rebound runner II and two symmetries at rebound, rebound runner II reduces from left to right gradually, can improve the flowability of the plastic liquid of sprue, guarantees that plastic liquid flows evenly.Compact conformation of the present invention, runner is reasonable, can carry out the multilayer material coextru-lamination, the plastic liquid good fluidity, cost is low, long service life, but the production and processing anti-wear performance is good, intensity is high, cost is low, security performance is good, the multilayer flexible PVC stair limited slip plate of good looking appearance, long service life.

The specific embodiment
Referring to Fig. 1 to Fig. 4, the present invention includes mouthful mould 1, mouth mould 22, cylinder manifold 3, rebound 4 and die body 5, described mouthful of mould 22 is provided with runner 1, described runner 1 is provided with runner one charging aperture 211 and three branch flow passages 212, described cylinder manifold 3 is provided with runner 2 31, described runner 2 31 is provided with runner two charging apertures 311, described rebound 4 is provided with rebound runner I41, the rebound side runner 43 of rebound runner II42 and two symmetries, described die body 5 is provided with main charging aperture 51, described mouthful of mould 1, mouth mould 22, cylinder manifold 3 is connected by screw 27 successively with rebound 4, and described rebound 4 is connected by screw 1 with die body 5.Described runner 2 31 increases from top to bottom gradually.Described rebound runner II42 reduces from left to right gradually.
During work, the flexible PVC material enters from the main charging aperture 51 of die body 5, can process the basic unit of stair limited slip plate, the flexible PVC material of waiting to be compounded in the basic unit is added in runner two charging apertures 311 of cylinder manifold 3, by runner 2 31, can be in basic unit coextru-lamination go out the second layer of stair limited slip plate, the flexible PVC material of waiting to be compounded on the second layer material is added in runner one charging aperture 211 of entrance mould 22, by three branch flow passages 212, but coextru-lamination goes out the 3rd layer of the stair limited slip plate.
