Description
Technical field
The utility model belongs to foamed board extrusion die apparatus technical field, particularly relates to a kind of many rack-styles foamed board 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 discharge pressure is unbalanced when causing extruding, need reserved more finished product surplus, carry out cutting finishing after the extrusion, thus result in a large amount of waste of raw materials, increase production cost.And, due in current Design of Dies, when fluid flow in runner, all have employed single passage, so flow into the amount of runner comparatively greatly at fluid, the flow velocity of fluid is not easy to control, and in the fluid short time, flow is larger, make the skewness of fluid, thus cause the defect of product.Current mould is after completing assembling, the sidepiece of its runner blow-by, when using so actual, need to increase a panel separately on upper/lower die, then at the sidepiece by these two panels, sealing plate being embedded into mould, thus the sealing to runner is completed.But this type of sealing means troublesome poeration, wastes time and energy, and affects the overall performance of whole mould.Due to can panel be embedded, cause panel and mold material disunity, thus make the mobility of fluid in mould inconsistent.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, there is provided a kind of fluid that makes more even when inflow runner, pressure is more balanced, fluid velocity has good controllability, seal operation to runner after the assembling of simplification mould, improve many rack-styles foamed board extrusion die that the mobility of fluid in mould is consistent, its technical scheme is as follows:
Many rack-styles foamed board extrusion die, comprise cope match-plate pattern and lower bolster, it is characterized in that, described cope match-plate pattern and lower bolster faying face form runner, several clothes hanger runners, shunting plasticising section, cushion chamber and polymerization foam chamber, die orifice, cushion chamber is shape small in ends broad in the middle, be provided with the first choked flow section between cushion chamber and polymerization foam chamber, between polymerization foam chamber and die orifice, be provided with the second choked flow section; Described runner is multiple flow passages feeding-passage, and each port of export place of multiple flow passages feeding-passage is connected with a clothes hanger runner respectively, and the port of export of clothes hanger runner is connected with the arrival end of shunting plasticising section.
Preferred embodiment is, the side of described upper die and lower die is structure as a whole formula, when cope match-plate pattern and lower bolster in conjunction with time, integrative-structure formula can complete sealing to the sidepiece of the faying face of cope match-plate pattern and lower bolster.
Preferred embodiment is, described clothes hanger runner from top to bottom shrinks gradually and communicates at the arrival end place of shunting plasticising section.
Many rack-styles foamed board extrusion die that the utility model provides, when in use, multiple flow passages feeding-passage can be divided into a plurality of fluids fluid and enter, and carries out preliminary shunting action to fluid, reduces the instantaneity flow of fluid.And the setting of multiple clothes hanger runner, can making the shunting that the fluid through tentatively shunting carries out again, fluid can well be made more even when inflow shunting plasticising section, fluid velocity has good controllability, and pressure is more balanced.
The side that the utility model is further provided with upper die and lower die is structure as a whole formula, when cope match-plate pattern and lower bolster in conjunction with time, integrative-structure formula can complete sealing to the sidepiece of the faying face of cope match-plate pattern and lower bolster.Thus just can a step realize operating the sealing of faying face after set of molds is installed, simplify the operation of runner sealing, the conforming performance of mould inner fluid flowing can well be improved simultaneously.
The further clothes hanger runner of the utility model from top to bottom shrinks gradually and communicates at the arrival end place of shunting plasticising section.Fluid distrbution can be made more even.
The beneficial effects of the utility model are: make fluid more even when flowing into runner, pressure is more balanced, fluid velocity has good controllability, and the seal operation to runner after the assembling of simplification mould, improves the mobility of fluid in mould consistent.

Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 3:
As shown in Figures 1 to 3, many rack-styles foamed board extrusion die, comprise cope match-plate pattern 1 and lower bolster 2, it is characterized in that, described cope match-plate pattern 1 and lower bolster 2 faying face form runner 3, several clothes hanger runners 4, shunting plasticising section 5, cushion chamber 6 and polymerization foam chamber 7, die orifice 9, cushion chamber 6, in shape small in ends broad in the middle, is provided with the first choked flow section 8 between cushion chamber 6 and polymerization foam chamber 7, is provided with the second choked flow section 10 between polymerization foam chamber 7 and die orifice 9; Described runner 3 is multiple flow passages feeding-passage, and each port of export place of multiple flow passages feeding-passage is connected with a clothes hanger runner 4 respectively, and the port of export of clothes hanger runner 4 is connected with the arrival end of shunting plasticising section 5.
Preferred embodiment is, described patrix 1 and the side of counterdie 2 are structure as a whole formula structure 11, when patrix 1 plate and counterdie 2 harden close time, integrative-structure formula 11 can complete sealing to the sidepiece of the faying face of cope match-plate pattern 1 and lower bolster 2.
Preferred embodiment is, described clothes hanger runner from top to bottom shrinks gradually and communicates at the arrival end place of shunting plasticising section.
First material carries out preliminary shunting through multiple flow passages feeding-passage, then enters in respective clothes hanger runner from the port of export of multiple flow passages feeding-passage, to the shunting that fluid carries out again.The entrance point of shunting plasticising section is flow into from the port of export of clothes hanger runner.Multiple rhombus is provided with protruding in shunting plasticising section.Protruding by the multiple rhombuses in shunting plasticising section, multiple rhombus projection has been divided into the small flow channels of multiple intercommunication whole shunting plasticising section, flow in the small flow channels of material between each rhombus projection, constantly carry out shunting rear interflow, then collaborate after shunting, thus making material significantly improve plasticizing and polymolecularity, outlet pressure is balanced product more easy-formation more.Material is by entering in cushion chamber after shunting plasticising section, and material carries out eliminating unbalanced extrusion pressure effect in cushion chamber, then by entering into after the first choked flow section in polymerization foam chamber.First choked flow section further eliminates the unbalanced extrusion pressure of material.Polymerization foam chamber mainly provides material foaming place, material is foamed more even.Extrude through die orifice finally by after the second choked flow section.Second choked flow section is the pressure that polymerization increases foam chamber.
