The invention discloses a multi-cavity injection mold with adjustable flow in flow channels. The injection mold comprises a bottom plate, sizing blocks are arranged on the two sides of the bottom plate, and a lower mounting plate and a lower mold plate are sequentially on the upper portion of the pair of sizing blocks. A plurality of lower mold cores are arranged in the lower mold plate, an uppermold plate is arranged on the upper portion of the lower mold plate, spacing blocks are arranged on the two sides of the upper mold plate in parallel, an upper flow channel plate and a lower flow channel plate are arranged between the spacing blocks, and the main flow channel and the branch flow channels communicating with upper mold cavities are formed in the lower flow channel plate. An upper mounting plate is arranged on the upper portion of the upper flow channel plate, upper cushion blocks are arranged on the two sides of the upper mounting plate in parallel, and a top plate is erected onthe upper portions of the two upper cushion blocks. A plurality of flow adjusting rods matched with the branch flow channels in position are arranged in the top plate through stepped through holes. Acircle of positioning bosses are arranged at the top ends of the flow adjusting rods, and a plurality of gaskets are detachably arranged on the portions, between the positioning bosses and the step surfaces of the stepped through holes, on the flow adjusting rods. The flow adjusting rods penetrate through an upper mold top plate, the upper mounting plate and the upper flow channel plate in sequence, and the bottom ends of the flow adjusting rods are located in the branch flow channels.
Description
technical field [0001] The invention relates to a multi-cavity injection mold. Background technique [0002] The flow rate in the flow channel of the traditional multi-cavity injection mold is not adjustable, and the flow rate and flow rate of the sub-runner near the main feed port is greater than the flow rate of the sub-runner far away from the main feed port, which causes the fluid pressure in the mold cavity at different positions Different, the injection flow rate of some products is too fast, and the parts on it are easily damaged by impact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-cavity injection mold with adjustable flow in the runner to improve product quality. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a multi-cavity injection mold, including a bottom plate arranged horizontally, an ejection hole is open...
