Straight rotary linkage core puller for injection mold of elbow product

Abstract

The invention discloses a straight rotary linkage core puller for an injection mold of an elbow product, comprising a recurved loose core (1), a connecting bar (2), a straight inside loose core (3), a straight outside loose core (4), an inclined guide slider (5), a lag bar (6) and an inclined guide pillar (7). The invention utilizes the technical scheme that the rotary core puller composed of therecurved loose core, the connecting bar, the straight inside loose core and the straight outside loose core is adopted, the straight inside loose core and the straight outside loose core are straightly pulled out in a segmentation mode successively by the inclined guide slider and the lag bar, and the connecting bar pulls the recurved loose core to pull cores rotatably, thus overcoming the problems and shortcomings of flanging on the outer walls of the product, much occupied labor, large working strength, low efficiency, high cost and latent accident potential in the prior art. By the provided straight rotary linkage core puller for the injection mold of the elbow product, automatic core pulling and demolding of the injection molding of the elbow product can be realized, thus achieving the purposes of removing flanging on the outer walls, reducing labor, lightening working strength, improving the production efficiency, lowering the cost and eliminating the accident potential.

Description

technical field [0001] The invention relates to a core-pulling and demoulding mechanism of an injection mold, specifically refers to a straight-line rotation linkage of an elbow product injection mold that is used for injection molding elbow pipe fittings and pulls the curved core out of the elbow pipe Core Pulling Mechanism Background technique [0002] The elbow is a connecting pipe fitting used for the bending position of the pipeline. The outer walls of the two ends of the elbow are provided with collars; the prior art injection molded elbow products use the splitting demoulding method to get out of the outer wall collars; the core demoulding method is adopted. The inner curved core block is ejected, that is, the curved core block is manually inserted into the mold to participate in the molding during injection molding. Pulling out, so it goes round and round; in actual production, multiple core inserts are usually prepared for turnover. [0003] The parting and demoul...

Problems solved by technology

[0003] The parting and demoulding method will form a parting flash on the outer wall of the elbow product; the production of the core block must be attended by someone, which requires a lot of labor and high work intensity; it takes time to place the core block manually, resulting in low production efficiency , high overall cost; if the manual placement of the core block is not in place, destructive accidents will occur, and if the manual placement of the core block encounters an accidental movement of the injection molding machine, work-related accidents will occur; therefore, there are flashes on the outer wall of the product in the prior art, The problems and deficiencies of taking up a lot of manpower, high work intensity, low efficiency, high cost, and potential accidents
