Pitched roof with large-angle and large moving route of plastic mold

Abstract

The invention discloses a pitched roof with a large-angle and a large moving route of a plastic mold, and belongs to the field of advanced manufacturing and automation. The plastic mold comprises a lower ejector plate, an upper ejector plate, a first fixing sleeve, a top rod, a lower template, a pitched roof head, a pitched roof angle guiding block and a pitched roof transverse guiding block. Thepitched roof with a large-angle and a large moving route of the plastic mold is reasonable in design, convenient to use, low in application cost and good in adaptability, according to the pitched roof, the angle of the pitched roof is 25 degrees, and the moving distance of the pitched roof can reach 23 mm. Through the arrangement of an oblique surface between the pitched roof head and the pitchedroof angle guiding block, in the process of pulling away the pitched rood head, large-angle demolding can be kept, through horizontal pushing of the pitched rood transverse guiding block, the pitchedrood can move along the pitched roof angle guiding block, the moving route is extended, an injection piece can be effectively assisted in completing ejecting operation, so that products cannot be damaged, the manufacturing cost is low, and it can be effectively solved that the long-distance moving phenomenon occur in the moving direction of the pitched roof.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing and automation, and in particular relates to an inclined roof with a large angle and a large movement stroke for a plastic mold. Background technique [0002] The inclined roof structure is often used in plastic molds. When the undercut along the moving direction of the inclined roof is relatively large, the moving distance of the inclined roof will increase. Generally, in order to avoid the jamming phenomenon caused by the reverse torque when the inclined roof is moving, the angle of the inclined roof should not be too large. The best mode is between 6°-8°, and it is not very stable if it exceeds 10°. The general design will increase the size of the inclined roof and take up space. The structure of the parts is complicated and the cost is high, and the parts often need to be replaced during the life cycle of the mold.
