Abstract

The utility model relates to a plastic grid plate molding device, which is a one-time molding extrusion grid plate machine head. The utility model can be used for making two kinds or many kinds of plastic grid plates of different rectangles, a structure for a clothes rack type machine head is adopted by the material entering end of the machine head, and rhombic choked flow blocks are arranged between an upper template and a lower template. In addition, the upper template is also provided with choked flow sticks so that the materials convenient flow in the width direction of the plates uniformly and the stably. The utility model also replaces the traditionally rolling process, simplifies the process flow, and lightens the operators' labor intensity. The product produced by using the one-step extrusion method of the utility model has light weight, the expense of raw materials is saved, and the production cost is reduced.

Description

The grate head is extruded in one-shot forming

The utility model relates to the parts of a kind of plastic grating plate (corrugated sheet) former, belongs to plastic products process technology equipment, is that the grate head is extruded in a kind of one-shot forming.

Existing plastic grating plate (corrugated sheet) unit is made up of extruder, head, vacuum sizing device, subsidiary engine etc.Mostly original production method is to adopt rolling process to produce sheet, forms waveform corrugation slab products through roll extrusion, applying then; This production method step complexity, investment are greatly, energy consumption is high, noise is big, automaticity is low, and increased white pollution greatly.

The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of extraordinary extruder head of making multiple rectangular grid daughter board is provided; This head adopts the coat-hanger die structure at feed end, and is provided with the rhombus choker bar between cope match-plate pattern and lower bolster; Also be provided with the choked flow rod in addition on cope match-plate pattern, it is uniform and stable on the width of plate to be convenient to materials flow; The utility model has replaced traditional rolling process, has simplified technological process.

The purpose of this utility model is achieved in that it includes cope match-plate pattern and lower bolster, and wherein said cope match-plate pattern and lower bolster one end are connected with the head connector of hollow cylinder structure, and the head connector is provided with groove; The other end of described cope match-plate pattern and lower bolster is die orifice narrow slit and vertical narrow slits, and the die orifice narrow slit is provided with to be adjusted plate and adjust plate down; On the cope match-plate pattern inboard, adjust the distolateral choked flow rod that also is equipped with of plate; Between cope match-plate pattern and lower bolster, be provided with the shunting core that has passage in addition; Described shunting core is a rhombus; Between described die orifice narrow slit and the vertical narrow slits is little rectangular block, has micropore on it and communicates with passage; The described adjustment plate of going up is installed in cope match-plate pattern and lower bolster opposite side with the following plate of adjusting

The utility model compared with prior art has the following advantages: technological process has been simplified in the employing of this head, has alleviated labor intensity of operating personnel; Under the equality strength condition, goods of the same area, the product weight of producing with a step extrusion molding of the present utility model is light, has saved cost of raw and processed materials greatly, has reduced production cost; In addition, the goods of producing with this head have that surface smoothness height, intensity are good, layer with layer between tearing strength height, withstand voltage experiment and impact experiment intensity height.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is die orifice narrow slit of the present utility model and vertical narrow slits structural representation.

Start shooting by an extruder among the figure, extrude different material (calcium carbonate, antioxidant, age resister etc. are wherein arranged) and enter head by connector 1, via cope match-plate pattern 3 and lower bolster 2 and by shunting core 4 through choked flow rod 5, on adjust plate 6, adjust plate 7 down and enter die orifice

narrow slit

8,9 and vertical narrow slits 10 places, extrude desirable plastic grating plate (corrugated sheet) goods thus; Wherein, the setting of choked flow rod 5 can guarantee that materials flow is uniform and stable on the plate width, thereby make the goods width even; Die orifice

narrow slit

8,9 places are provided with and adjust plate 6 and adjust plate 7 down, can control the thickness of goods, extrude the plastic grating slab products of different-thickness; In addition, shunting core 4 is divided into the upper and lower two-layer die orifice

narrow slit

8,9 that enters with materials flow, forms upper and lower two surfaces of grate; Be cut with vertical narrow slits 10 on shunting core 4 vertical direction, materials flow enters the back and at the die orifice place upper and lower faces is connected to form muscle, can form rectangular opening or tri-angle-holed; For preventing that plastic products from subsiding, on shunting core 4, have passage 12, on each little rectangular block of core rod discharging opening place, have micropore 11 and communicate with passage 12, suitably feed compressed air in case of necessity and match with the Vacuum shaping template, make the goods cooling and shaping.
