Description
Technical field
The invention belongs to the plastic material processing technique field, be specifically related to a kind of stock mould that section bar inside is carried out cooling and shaping.
Background technology
For the less plastic irregular profile of opening, as shown in Figure 1, cooling water and vacuum pneumatic passage are difficult to be incorporated into section bar 14 inside by conventional design method, thereby can't cool off and finalize the design section bar inside.Cooling duct and vacuum pneumatic passage then do not have the effect of negative pressure of vacuum if do not arrange in section bar inside, and the section bar inside dimension can't be guaranteed; And there is not the cooling of cooling water; The inner stock mould template of section bar can not be cooled off fast, and the heat on the section bar can be transmitted on the template gradually, causes the template temperature to rise gradually; Finally can cause section bar effectively not cooled off and stifled mould phenomenon occurs, this will have a strong impact on the steady production of section bar.
Summary of the invention
The purpose of this invention is to provide and a kind of the stock mould of cooling and shaping is carried out in section bar inside, this stock mould is cooled off section bar effectively and finalizes the design, and has guaranteed the production that section bar can steady and continuous.
For realizing the foregoing invention purpose; The technical scheme that the present invention adopted is: a kind of stock mould that section bar inside is carried out cooling and shaping; This stock mould is the casing shape; Surround between the template of stock mould and form the die cavity that supplies section bar to pass through; At least one template of said stock mould extend into the inner space of section bar along the open-mouth of section bar, and the template that extend into the section bar inner space is provided with cooling water pipeline that is connected with cooling water source and the vacuum line that is connected with vacuum source, and the water side of said cooling water pipeline is extruded direction along section bar and stretched out in the stock mould outside and with cooling water tank and be connected.
Simultaneously, the present invention can also be able to further realization through following technical measures:
Said die cavity diminishes from the discharge end of feed end to the die cavity of die cavity along the opening size perpendicular to the profile length direction gradually, and the edge of die cavity matches perpendicular to the edge of the opening size of profile length direction and the section bar opening size perpendicular to the profile length direction each other.
The die cavity of said stock mould is surrounded jointly and is formed by the cope match plate that is positioned at upside, the preceding template and the back template that are positioned at the following template of downside and are positioned at both sides; The extension of template extend into the inner space of section bar before said; The top of said cope match plate is provided with cover plate, and the bottom of following template is provided with platen; Be provided with the gentle duct, road, water hole of leading to the die cavity place on said cope match plate, following template and the back template; Said each road, water hole is connected with cooling water source through second water swivel that is arranged on cope match plate and the following template respectively, and each pore road is connected with vacuum source through the second gas joint that is arranged on cover plate and the platen respectively.
Road, water hole on said each template by main priming hole, divide priming hole and constitute near the cooling water hole at die cavity place; The water inlet end of said main priming hole be arranged on cope match plate or down second water swivel on the template be connected; The water side of main priming hole is connected with a plurality of cooling water holes that extend along the profile length direction through minute priming hole, and the water side of cooling water hole is connected with cooling water tank.
Pore road on said each template is made up of pore and first air drain that is arranged near the die cavity place, and said pore is connected with the said second gas joint through the air chamber that is arranged on cover plate or the platen, and pore is connected with said first air drain.
To be provided with cooling water source be first water swivel that water pump is connected to the front end of extruding direction along section bar of template before said; Said first water swivel is connected with a plurality of cooling water channels that extend along the profile length direction through penstock; The water side of cooling water channel is connected with cooling water tank; Said penstock and cooling water channel all are arranged in the preceding template, and the said cooling water pipeline of the common composition of first water swivel, penstock and cooling water channel.
To be provided with vacuum source be the first gas joint that vavuum pump is connected to the front end of extruding direction along section bar of template before said; The said first gas joint is connected through the vacuum chamber of bleed road with the closed that extends along the profile length direction, and said vacuum chamber is connected through a plurality of second air drains that prop up pore and be arranged on the side of preceding template extension week; Said bleed road, vacuum chamber and a pore all are arranged in the preceding template, and the said vacuum line of the common composition of bleed road, vacuum chamber, a pore and second air drain.
Template is provided with the diversion basin of closed before said between penstock and cooling water channel, and the water side of penstock is connected with the water inlet end of diversion basin, and the water inlet end of each cooling water channel is connected with the water side of diversion basin.
Said vacuum chamber is along perpendicular to the cross section of profile length direction in the form of a ring or arcuation.
Said each cooling water channel is distributed on the extension that extend into the section bar inner space of preceding template in the form of a ring, and each cooling water channel all is arranged on the position near die cavity of extension.
Beneficial effect of the present invention is: among the present invention by cope match plate, preceding template, back template and down template surround and form the die cavity that supplies the through state that section bar passes; The feed end of said die cavity and the opening size of discharge end change, promptly the edge of die cavity perpendicular to the feed end opening size of profile length direction greater than its discharge end opening size.Because die cavity diminishes from the discharge end of feed end to the die cavity of die cavity along the opening size perpendicular to the profile length direction gradually; Again since the edge of die cavity match each other perpendicular to the edge of the opening size of profile length direction and section bar opening size perpendicular to the profile length direction; Therefore section bar is bigger perpendicular to the opening size of profile length direction on the edge at die cavity feed end place; So that cooling water and vacuum pneumatic passage are incorporated on the inner preceding template of section bar; The discharge end that at the discharge end of stock mould also is die cavity returns to the required size of section bar opening with the opening size of die cavity; Before this moment in the template cooling water in the cooling water pipeline directly flow to stock mould and extrude in the cooling water tank of direction rear side along section bar, thereby realized section bar inside is cooled off and finalized the design, guaranteed the production that section bar can steady and continuous.
