Abstract
The utility model discloses a EPP expanded plastics extrusion tooling, it finely tunes bolt (2), choked flow stick adjusting bolt (4), its characterized in that to include the mould body (7), flange (6), locking bolt (3), die lip temperature measuring head (1), lower die lip (11), lower die lip fastening bolt, go up the die lip: the mould body is gone up and is equipped with several fuse -element temperature along the mould width orientation and detects head (5), leans on the fuse -element temperature to detect the other several melt pressure that still is equipped with of head and detects head (8), and the upper surface of lower die lip be the arc, and lower die lip be adjustable, and a number of pass tie bolt (9) links to each other with the mould body, and the setting of mould body lower surface has several tops to move bolt (10), and the head and the lower die lip lower surface apical grafting of bolt are moved to the top. Because the upper surface of die lip is the arc down, makes the export of mould become the arc export. And puller bolt and tie bolt's use, the shape that also can adjust the arc export.
Description
Technical field
This utility model relates to a kind of mould of plastics, particularly relates to a kind of EPP foamed plastic extrusion die.
Background technology
It is known that indoor (outward) decoration of the most domestic auto industry, war industry, boats and ships, building trade etc. and medicine, packaging industry need substantial amounts of plastic foam material.Manufacture plastic foam material and necessarily involve foaming mould device.The common plastics extrusion die that Vehicles Collected from Market makes is not applied for the needs of EPP foaming.The feature of common plastics extrusion die is that die orifice aperture pitch is relatively big, and for 2-10mm, cavity pressure is less, about 2Mpa, and mould is unlikely to deform, on product without impact when temperature is higher.And the feature that EPP expanded material requires mould is that die orifice aperture pitch is less, it is about 0.1mm-3mm, cavity pressure is bigger, it is about 7-25Mpa, because of when EPP expanded material is extruded cavity pressure increase after at high operating temperatures mould be easily deformed, the thickness that there is extrusion foaming sheet material can not control, i.e. thickness error fluctuates in the range of 30-60%, it is impossible to normally produce qualified products；The foamed gas that die orifice is miscible in plastic melt after increasing deformation with pressure is easily escaped, and affects expansion density and effect, cannot foam time serious.
Utility model content
The purpose of this utility model is that providing a kind of to overcome the deficiencies in the prior art can reliably control die deformation, the normal EPP foamed plastic extrusion die produced of realization.Its concrete technical scheme is: EPP foamed plastic extrusion die includes mold, adpting flange, clamping screw, die lip temperature detection head, lower die lip, lower mold lockjaw fixing bolt, upper die lip trimming bolt, choked flow rod regulation bolt, it is provided with several melt temperature detection head along die width direction on mold, by being additionally provided with several melt pressure detection head by melt temperature detection head, the upper surface of lower die lip is arc, lower die lip is adjustable member, bolt is pulled to be connected with mold by several, mold lower surface is provided with several and pushes bolt, push the head of bolt and lower die lip lower surface apical grafting.
Described several melt temperatures detection head, its quantity is 11, is evenly arranged along die width direction.
Described several melt pressures detection head, its quantity is 3, lays respectively at two close end and middle part.
When using this utility model EPP foamed plastic extrusion die, first load onto wire stitcher by adpting flange, be then connected with EPP foamed plastic outlet of extruder, adjust accordingly according to the thickness of required production sheet material, can normally produce.
From the technical solution of the utility model it can be seen that owing to the upper surface of lower die lip is arc, make the outlet of mould become arc outlet.And push bolt and pull the use of bolt, it is also possible to the shape of regulation arc outlet.Add the melt temperature detection head set up and melt pressure detection head, can fully grasp the temperature and pressure situation of change of mould, be adjusted correspondingly according to its change.Solve the problem that original mould is easily deformed, fully meet this utility model and can reliably control die deformation, realize the normal goal of the invention produced.

Fig. 2 is the Way out schematic diagram of this utility model EPP foamed plastic extrusion die；
Fig. 3 is the die lip partial cutaway view schematic of this utility model EPP foamed plastic extrusion die.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1, see accompanying drawing 1-3, EPP foamed plastic extrusion die includes mold 7, adpting flange 6, clamping screw 3, die lip temperature detection 1, lower die lip 11, lower mold lockjaw fixing bolt, upper die lip trimming bolt 2, choked flow rod regulation bolt 4, it is provided with several melt temperature detection 5 along die width direction on mold, by being additionally provided with several melt pressure detection 8 by melt temperature detection head, the upper surface of lower die lip is arc, lower die lip is adjustable member, bolt 9 is pulled to be connected with mold by several, mold lower surface is provided with several and pushes bolt 10, push the head of bolt and lower die lip lower surface apical grafting.Described several melt temperatures detection head, its quantity is 11, is evenly arranged along die width direction.Described several melt pressures detection head, its quantity is 3, lays respectively at two close end and middle part.
