Description
Technical field
The utility model belongs to foamed board extrusion die apparatus technical field, particularly relates to a kind of cope match-plate pattern 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 needs reserved more sheet material when causing extruding, and is carrying out cutting finishing after the extrusion, thus result in a large amount of waste of raw materials, 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 a kind of extrusion board of model, so the model of producing is less, mould is more, causes cost to increase and management trouble.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of flow passage design, can save raw material, and can regulate the cope match-plate pattern of PVC foam plate extrusion die of runner size, and 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 comprises 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 comprises mainboard body and elasticity mouth mould, offers short slot, be provided with set screw in described short slot between described mainboard body and elasticity mouth mould.
The cope match-plate pattern of the PVC foam plate extrusion die that the utility model provides, needs to install and use with the lower bolster combination of PVC foam plate extrusion die 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 the flowing of raw material in runner more reasonable, thus when making to extrude, the reserved section of finished product reduce, thus Loss reducing amount, cost-saving.
Being arranged so that of elasticity mouth mould and set screw can act on elasticity mouth mould by set screw, compressing elasticity mouth mould thus the adjustment carried out runner size, makes a width mould can adapt to the extruded product of Multiple Type, reduces cost and be convenient to management.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of PVC foam plate extrusion die.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 2:
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 comprises 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, be 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, be provided with half second choked flow section 35.
Preferred embodiment is, described plate body 1 comprises mainboard body 11 and elasticity mouth mould 12, offers short slot 13 between described mainboard body 11 and elasticity mouth mould 12, is provided with set screw 14 in described short slot 13.
When in use, raw material through semisplit plasticising section 31 through shunting after, enter in half cushion chamber 32, enter in half first choked flow section after more than half cushion chamber 32 makes raw material remove corresponding stress, half first choked flow section entirety is comparatively long and narrow, so by strengthening its extrusion pressure 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.
