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 large crooked adjusting device of a kind of plastics.
Background technology
Hollow material is by the dry vacuum stock mould, even the even cooling and shaping in each limit, section bar finally also can produce the buckling deformation of outside projection, 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, stable produce high-quality section bar, the surface of mould cavity of stock mould and shaped block is designed to the opposite convex surface of section bar protrusion direction, 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, opposite direction, and relief section bar is shrinking without continuing cooling under the restrained condition, and the evagination amount of warpage of generation is just in time offset the anti-amount of warpage that causes, thereby obtains straight section bar wall.But, anti-amount of warpage is to be determined by factors such as section bar hauling speed, different convection transfer rate (comprising water temperature, hydraulic pressure and vacuum etc.), wall thickness, but water temperature, hydraulic pressure, these factors of vacuum produce deviation easily when regulating, 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 exerted an influence.
Summary of the invention
The invention provides a kind of the adjusting with the vacuum of negative pressure of vacuum water tank and match, guarantee large crooked adjusting device of plastics of the plane quality of special section visible surface.
Technical solution problem of the present invention provides following scheme:
Large crooked adjusting device of a kind of plastics, comprise upper and lower shaped block, it is characterized in that: link together by attachment screw between the described upper and lower shaped block, be provided with the typing chamber between the described upper and lower shaped block, the middle part of described upper shaped block is equipped with anti-amount of warpage adjustment screw, the lower end of described anti-amount of warpage adjustment screw connects adjusted silk seam, and anti-amount of warpage plug screw is installed on the described lower shaped block, and the upper end of described anti-amount of warpage plug screw withstands on lower adjusting silk and sews on.
Be provided with positioning key between the described upper and lower shaped block.
The present invention is in the first segment water tank shaped block except water shutoff design adjustment screw and regulate the silk seam, by adjustment screw to regulate the silk seam tighten and loosen, regulate the anti-amount of warpage of shaped block type single face, guarantee the plane quality of special section visible surface.
Description of drawings
Fig. 1 is structural representation of the present invention.
