Abstract
The invention belongs to foamed board extrusion die apparatus technical field, particularly relate to the cope match-plate pattern of a kind of PVC foam plate extrusion die.The invention discloses the cope match-plate pattern of a kind of PVC foam plate extrusion die, it is characterized in that, the cope match-plate pattern of described PVC foam plate extrusion die includes plate body, the bottom of described plate body offers half die orifice and half runner, half described runner is divided into semisplit plasticising section, half cushion chamber and is partly polymerized foam chamber, half cushion chamber is shape small in ends broad in the middle, is provided with half first choked flow section, is provided with half second choked flow section between half polymerization foam chamber and half die orifice between half cushion chamber and half polymerization foam chamber.Flow passage design of the present invention, it is possible to save raw material, and runner size can be regulated.
Description
Technical field
The invention belongs to foamed board extrusion die apparatus technical field, particularly relate to the cope match-plate pattern of a kind of PVC foam plate extrusion die.
Background technology
The design of the flow passage structure that current cope match-plate pattern and lower bolster are formed after bonding is unreasonable, thus causes needing reserved more sheet material when of extrusion, is carrying out cutting finishing after the extrusion, thus result in substantial amounts of waste of raw materials, is increasing production cost.And the size of runner that current cope match-plate pattern and lower bolster are formed after bonding is all changeless, so when in use a width mould corresponding be all the extrusion board of a kind of model, so the model produced is less, mould is more, causes cost to increase and management trouble.
Summary of the invention
It is an object of the invention to solve techniques discussed above problem, it is provided that a kind of flow passage design, it is possible to saving raw material, and can regulate the cope match-plate pattern of the PVC foam plate extrusion die of runner size, its technical scheme is as follows:
A kind of cope match-plate pattern of PVC foam plate extrusion die, it is characterized in that, the cope match-plate pattern of described PVC foam plate extrusion die includes plate body, the bottom of described plate body offers half die orifice and half runner, half described runner is divided into semisplit plasticising section, half cushion chamber and is partly polymerized foam chamber, half cushion chamber is shape small in ends broad in the middle, is provided with half first choked flow section, is provided with half second choked flow section between half polymerization foam chamber and half die orifice between half cushion chamber and half polymerization foam chamber.
Preferred embodiment is, described plate body includes mainboard body and elastic mouth die, offers short slot, be provided with set screw in described short slot between described mainboard body and elastic mouth die.
The cope match-plate pattern of the PVC foam plate extrusion die that the present invention provides, needs the combination of the lower bolster with PVC foam plate extrusion die to install and use when in use.Semisplit plasticising section, half cushion chamber of cope match-plate pattern and be partly polymerized foam chamber, half first choked flow section, half second choked flow section and lower bolster and be combined into whole runner.Make raw material flowing in runner more reasonable, so that the reserved section of finished product reduces the when of extrusion, thus reduce waste, cost-effective.
The setting of elastic mouth die and set screw allows to be acted in elastic mouth die by set screw, oppresses elastic mouth die thus carries out the regulation to runner size so that a width mould can adapt to the extruded product of Multiple Type, reduces cost and be easy to management.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the schematic diagram of PVC foam plate extrusion die.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2 specific illustrative embodiment:
As depicted in figs. 1 and 2, a kind of cope match-plate pattern of PVC foam plate extrusion die, the cope match-plate pattern of described PVC foam plate extrusion die includes plate body 1, the bottom of described plate body 1 offers half die orifice 2 and half runner 3, half described runner 3 is divided into semisplit plasticising section 31, half cushion chamber 32 and half polymerization foam chamber 33, half cushion chamber 32 is in shape small in ends broad in the middle, it is provided with half first choked flow section 34 between half cushion chamber 32 and half polymerization foam chamber 33, between half polymerization foam chamber 44 and half die orifice 2, is provided with half second choked flow section 35.
Preferred embodiment is, described plate body 1 includes mainboard body 11 and elastic mouth die 12, offers short slot 13, be provided with set screw 14 in described short slot 13 between described mainboard body 11 and elastic mouth die 12.
When in use, raw material through semisplit plasticising section 31 through shunting after, enter in half cushion chamber 32, raw material are made to enter in half first choked flow section after removing corresponding stress through more than half cushion chambers 32, half first choked flow section entirety is the longest and the narrowest, so by its extrusion pressure can be strengthened after half first choked flow section.Fully foam after destressing after entering into half polymerization foam chamber, through half long and narrow second choked flow section through half die extrusion.
