PPR (pentatricopeptide repeats) pipe casing lamination-injection mould

Abstract

A PPR (pentatricopeptide repeats) pipe casing lamination-injection mould comprises an upper mould cavity and a lower mould cavity composed of a fixed mould cavity plate, a moving mould cavity plate and a moving mould plate. Each of the upper mould cavity and the lower mould cavity contains a plastic part. Large slides are disposed on two sides of the moving mould plate and driven by inclined guide posts. Slider cores are mounted on the inner side of the large sliders and extend into the inner wall of a plastic part. The PPR pipe casing lamination-injection mould is characterized in that runner inserts, a runner cutoff mechanism and a top branch runner device are mounted between the large sliders, the runner cutoff mechanism comprises a fixed cutting block which is connected with a first cut piece and a second cut piece through positioning pins, the first cut piece and second cut piece are inserted into the runner inserts, the top branch runner device comprises connecting blocks, a limit screw is mounted on each connecting block and connected with the large sliders, one connecting block is connected with a corresponding top plate wedge, runner ejector pins, ejector springs and top plates are mounted in the moving mould plate, and the head of each too plate is abutted to a distribution handle and provided with a tapped wedged groove matched with a corresponding tapered wedge.

Description

Technical field [0001] The invention relates to a PPR pipe sleeve laminated injection mold, which is mainly applied to a row mold with sliding blocks on both sides of a plastic part, and belongs to the field of plastic molds. Background technique [0002] Use plastic molds to produce plastic products, such as PPR pipe sleeves and other plastic parts. At present, a row of plastic molds with sliders installed on both sides of the mold template are generally used. The disadvantage is: due to the limitation of the length of the runner, it can only be used One mold with one cavity or one mold with few cavities has low utilization rate and production efficiency of injection molding machine, and high cost. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cutting mechanism to cut off the flow channel (remaining material) when the slider slides, and the ejection mechanism to push the branch flow channel (m...
