Abstract
The utility model discloses a plastic large face bending adjusting device which comprises an upper forming block and a lower forming block. The upper forming block is connected with the lower forming block through screws. A forming cavity is formed between the upper forming block and the lower forming block. An anti-warpage adjusting screw is mounted in the middle of the upper forming block. The lower end of the anti-warpage adjusting screw is connected with an upper adjusting screw seam. An anti-warpage plug screw is mounted on the lower forming block. The upper end of the anti-warping quantity plug screw is butted against a lower adjusting screw seam. Single anti-warpage of the forming blocks is adjusted in coordination with vacuum adjusting of a vacuum negative pressure water tank to guarantee plane quality of visual faces of special-shaped materials, and accordingly design deficiency is made up, and adaptability to extrusion processes is increased.
Description
Technical field
The utility model relates to big 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 to outer lug, and amount of warpage is along with the length of side monotone increasing of section bar frame, and this is consistent with the practice of extrusion die.At present, for addressing this problem, stable produce high-quality section bar, the die cavity wall 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, and direction is opposite, and relief section bar continues cooling and shrinks under no 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 are easy to generate deviation when regulating, these deviations can cause big of section bar straight inadequately, shape is accurate inadequately, influence the apparent mass of section bar, even the physical property of section bar is exerted an influence.
The utility model content
The utility model provides a kind of the adjusting with the vacuum of negative pressure of vacuum water tank to match, and guarantees big crooked adjusting device of plastics of the plane quality of special-shaped material visible surface.
The utility model technical solution problem provides following scheme:
Big 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, described middle part of going up 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, describedly on the shaped block anti-amount of warpage plug screw is installed down, and the upper end of described anti-amount of warpage plug screw withstands on down to regulate and thread sews on.
Be provided with positioning key between the described upper and lower shaped block.
The utility model 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-shaped material visible surface.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, big crooked adjusting device of a kind of plastics, comprise upper and lower shaped block 1,2, link together by attachment screw 3 between the described upper and lower shaped block 1,2, be provided with typing chamber 4 between the described upper and lower shaped block 1,2, described middle part of going up shaped block 1 is equipped with anti-amount of warpage adjustment screw 5, the lower end of described anti-amount of warpage adjustment screw 5 connects adjusted silk seam 6, on the shaped block 2 anti-amount of warpage plug screw 7 is installed under described, the upper end of described anti-amount of warpage plug screw 7 withstands on down to be regulated on the silk seam 8, is provided with positioning key 9 between the described upper and lower shaped block 1,2.
Claims (2)
