Abstract
The utility model discloses a formation device for an inner foamed plastic plate, which is composed of a left form panel (2), a right form panel (3), a core form (4), a form lip (5), a forming lip (6), a forming form (7), etc. The utility model is characterized in that a feed inlet is arranged on the core form (4); two diversion holes (11), a clothes rack type plane-surface flow channel (12) and a slope interval-layer flow channel (13) are arranged on the core form (4) and are matched with the feed inlet, and flow materials are guaranteed to be separated firstly and then be collected. The forming lip (6) is provided with a cooling flow channel (18), and the surfaces of the confluent feed streams are processed by cooling to realize the purposes that the middle of a plate is foamed and the two skin layers of the plate are not foamed. The utility model has the advantages of reasonable and compact structure, low cost and convenient operation; besides, the quality of the produced plate is high.
Description
The utility model belongs to the plastic plate manufacturing machine, specifically a kind of interior foamed plastic plate forming device.
Interior foamed plastic sheet material is a kind ofly can be widely used in building, the new material that decoration and furniture are made, its top layer is hard closely knit, inside is foaming structure, smooth in appearance is attractive in appearance, it is little to have proportion, in light weight, anticorrosion, fire-retardant, insulation, sound insulation, protecting against shock, characteristics such as rub resistance, simultaneously, saw, dig, nail, bore, bonding, weld all very conveniently, at present, developed this series products in minority developed country, having developed a kind of intermediate layer as Baden, Germany Felder company is foaming layer, the sheet material that two top layers are composited for not foaming layer, this plate foaming layer has tangible interface, yielding bending with not foaming layer, produce the equipment complexity of this kind sheet material, need three extruders, its plate forming device is provided with three charging apertures, and inside is provided with three runners, the material that every extruder extruded is walked a charging aperture, a runner, the material that last three runners the come out sheet material that is composited, therefore, investment is big, cost height, operating procedure also are difficult for grasping.
It is little that the purpose of this utility model provides a kind of investment, cost is low, equipment is simple, maneuverable can the production foaming layer not have interfacial with not foaming layer, be difficult for diastrophic interior foamed plastic plate forming device, produce interior foamed plastic sheet material with this device, only need an extruder, spout with auxiliary agents such as the HPVC powder that stirs and blowing agent batching foamed plastic plate forming device in the extruder plasticizing is clamp-oned, install ad hoc runner by this, under certain pressure and temperature condition, once obtain desirable interior foamed plastic sheet material from products export.
The utility model is achieved in that the utility model is by left-right template, core, die lip, the core lip, the typing lip, the runner slack adjuster, heating system, cooling system, stock moulds etc. are partly formed, on core, be provided with a spout, material extrusion direct and extruder links during use, be provided with two tap holes below the spout successively, rack-style plane runner, inclined-plane clearance layer runner, realize materials flow deciliter, materials flow is divided into two roads through tap hole, progressively form the uniform laminar flow of thickness, and converge at the depressor area of core lip end, because the space increases suddenly, make the foamed gas in the plastic solution expanded foamed rapidly, but the outside at two layered materials stream, because near the typing lip, the quenching that is subjected to cooling fluid is handled, and foamed gas sharply shrinks, thereby it is closely knit hard to form the top layer, internal layer is the sheet material parison of foaming structure, and then enter the stock mould processing of further finalizing the design, can obtain sheet forming.
The utility model has the advantages that: work simplification, easy to operate, compare with the product of Baden, Germany Felder company, can reduce by two extruders, reduce hold facility and floor space, also reduced the energy consumption in the production process simultaneously, reduced the production cost of sheet material, percent defective when having reduced start, make product quality be more convenient for controlling, simultaneously, the sheet material that uses the utility model to produce, there is not tangible interface between top layer and the foaming layer, be difficult for producing bending, this sheet material is compared with the similar sheet material that Germany produces, and is guaranteeing under the constant prerequisite of its every physical performance index, its averag density is lower, and shock resistance and processing characteristics are better.
Accompanying drawing 1 is looked schematic diagram for the utility model master.Accompanying drawing 2 is that the utility model is along the A-A cut-away view.Accompanying drawing 3 is the utility model stock mould schematic diagram.In the accompanying drawing: 1-connects neck, 2-left side template, and the right template of 3-,
