Abstract
The invention discloses a plastic large plane bending regulation device. The plastic large plane bending regulation device comprises an upper molding block and a lower molding block, wherein the upper molding bock is connected with the lower molding block through connection bolts; a molding cavity is formed between the upper molding block and the lower molding block; an anti-warpage regulating screw is mounted at the middle part of the upper molding block; an upper adjusting screw thread is connected with the lower end of the anti-warpage regulating screw; an anti-warpage screw plug is mounted on the upper lower molding block; and the upper end of the anti-warpage screw plug butts against a lower adjusting screw thread. The plastic large plane bending regulation device can be used for regulating the single-side anti-warpage amount of the molding block, and can ensure the plane quality of the visual surface of a profile in combination with vacuum degree regulation of a vacuum negative-pressure water tank, thereby overcoming the disadvantages on design and enhancing the adaptability to the extrusion process.
Description
Technical field
The present invention relates to a kind of plastics large bending adjusting device.
Background technology
Hollow material is by dry vacuum stock mould, even if the sizing of each limit Homogeneous cooling, section bar finally also can produce the buckling deformation of outwardly convex, and amount of warpage is along with the length of side monotone increasing of frame of section bar, and this is consistent with the practice of extrusion die.At present, for addressing this problem, the stable section bar producing high-quality, the surface of mould cavity of stock mould and shaped block is designed to the contrary convex surface of section bar protrusion direction, and the bossing of convex surface is called anti-amount of warpage.The size of anti-amount of warpage is consistent with the amount of warpage of section bar, and direction is contrary, and most relief section bar is without continuing cooling meat under restrained condition, and the evagination amount of warpage of generation just in time offsets the anti-amount of warpage caused, thus obtains straight section bar wall.But, anti-amount of warpage is determined by factors such as section bar hauling speed, different convection transfer rate (comprising water temperature, hydraulic pressure and vacuum etc.), wall thickness, but these factors of water temperature, hydraulic pressure, vacuum easily produce deviation when adjustment, these deviations can cause large of section bar straight not, shape is accurate not, affect the apparent mass of section bar, even the physical property of section bar is had an impact.
Summary of the invention
The invention provides a kind of adjustment with the vacuum of negative pressure of vacuum water tank to match, ensure plastics large bending adjusting device of the plane quality of special section visible surface.
Technical solution problem of the present invention provides following scheme:
A kind of plastics large bending adjusting device, comprise upper and lower shaped block, it is characterized in that: linked together by attachment screw between described upper and lower shaped block, sizing chamber is provided with between described upper and lower shaped block, the middle part of described upper shaped block is provided with anti-amount of warpage adjustment screw, the lower end of described anti-amount of warpage adjustment screw connects the upper silk that regulates and stitches, and described lower shaped block is provided with anti-amount of warpage plug screw, and the upper end of described anti-amount of warpage plug screw withstands on lower adjustment silk and sews on.
Positioning key is provided with between described upper and lower shaped block.
The present invention designs adjustment screw and regulates silk seam in the first segment water tank shaped block except water shutoff, by adjustment screw to regulate silk seam tighten and loosen, regulate sizing block-type one side anti-amount of warpage, ensure the plane quality of special section visible surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of plastics large bending adjusting device, comprise upper and lower shaped block 1,2, linked together by attachment screw 3 between described upper and lower shaped block 1,2, sizing chamber 4 is provided with between described upper and lower shaped block 1,2, the middle part of described upper shaped block 1 is provided with anti-amount of warpage adjustment screw 5, the lower end of described anti-amount of warpage adjustment screw 5 connects the upper silk that regulates and stitches 6, described lower shaped block 2 is provided with anti-amount of warpage plug screw 7, the upper end of described anti-amount of warpage plug screw 7 withstands on lower adjustment silk seam 8, is provided with positioning key 9 between described upper and lower shaped block 1,2.
