Abstract
The injection mold for rotary brush holder of vacuum cleaner includes one lower mold plate, one material plate driven with the injection molding mechanism, one upper mold plate, one longitudinal upper mold core and one longitudinal lower mold core. The upper mold plate and the upper mold core constitute the upper mold; the lower mold plate and lower mold core constitute the lower mold; and the upper mold and the lower mold enclose the forming mold cavity. Beside the lower mold plate, there is also one ejecting mechanism driven by the injection molding machine to push out the product from the mold core. There are also one upper mold cylinder for locating the upper mold plate and one lower mold cylinder for locating the lower mold plate. The present invention has unique mold structure for forming the rotary brush holder with spiral brittle mounting slot.
Description
(1) technical field
The present invention relates to a kind of injection mold for rotary brush holder of vacuum cleaner.
(2) background technology
Rotary brush is an important accessory in the dust catcher, and the dust removal ability when rotating in order to improve is thirsted for the bristle mounting groove on the rotary brush holder is done spirality, but wanted the such rotary brush holder of moulding to have higher difficulty.
(3) summary of the invention
For the helical rotary brush holder of moulding bristle mounting groove, the invention provides a kind of injection mold for rotary brush holder of vacuum cleaner with special construction.
The technical scheme that the present invention solves its technical problem is: a kind of injection mold for rotary brush holder of vacuum cleaner, comprise lower bolster, be subjected to the flitch that draws of injection machine driving, cope match-plate pattern, go up longitudinally core and descend core longitudinally, described lower bolster is fixed on the counterdie fixed head, described cope match-plate pattern is fixed on the upper mould fixed plate, described cope match-plate pattern and last core are formed patrix, described lower bolster and described core are down formed counterdie, described patrix and described counterdie surround shaping mold cavity, described lower bolster one side also is provided with the ejecting mechanism that is used for goods are ejected core that driven by injection machine, the described whole core of going up core and the described cooperation of core down composition S shape, described go up core rotatably install with described cope match-plate pattern on, described core down rotatably install with described lower bolster on; Also comprise upper mould oil cylinder and lower mold oil cylinder, the knock-pin of described upper mould oil cylinder and first backstay are affixed, first draw-in groove is arranged on the described cope match-plate pattern, described first backstay is over against described first draw-in groove, the knock-pin of described lower mold oil cylinder and second backstay are affixed, second draw-in groove is arranged on the described lower bolster, and described second backstay is over against described second draw-in groove.
Further, describedly go up core and be fixed on the top rotary table, described core down is fixed on the lower rotary table, described cope match-plate pattern is provided with cylinder, described top rotary table is set in described going up on the cylinder rotationally, described lower bolster is provided with down cylinder, and described lower rotary table is set on the described cylinder down rotationally.
Further, ejecting mechanism comprises top board that is subjected to the injection machine driving and the push rod of being located on the described top board, and described push rod is towards described shaping mold cavity.
During injection moulding, the mould clamping is on injection machine, and molten plastic is injected in the shaping mold cavity, and in the chamber cooling and shaping.In the die sinking process, at first the lower mold oil cylinder action snaps in second backstay in second draw-in groove, make the lower bolster location, the upper mould oil cylinder action withdraws from first backstay from first draw-in groove, be accompanied by and draw flitch and cope match-plate pattern to separate, pull out from sprue to guarantee stub bar, follow cope match-plate pattern, lower bolster slowly separates, rely on the withdrawing power of die sinking this moment, makes the core rotation, thereby guarantee that plastic breaks away from patrix, up to cope match-plate pattern, after lower bolster separates fully, the lower mold oil cylinder action withdraws from second backstay from second draw-in groove, and the upper mould oil cylinder action snaps in first backstay in first draw-in groove, then by injection machine top board is ejected, by push rod goods are ejected, rely on ejecting force, following core rotation is deviate from from counterdie until plastic.Matched moulds and begin a new injection cycle more afterwards.
The present invention designs unique mould structure, has realized the helical rotary brush holder of moulding bristle mounting groove.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
With reference to Fig. 1, a kind of injection mold for rotary brush holder of vacuum cleaner, comprise lower bolster 1, be subjected to drawing flitch 2, cope match-plate pattern 3, go up core 4 longitudinally and descending core 5 longitudinally of injection machine driving, described lower bolster 1 is fixed on the counterdie fixed head 6, described cope match-plate pattern 3 is fixed on the upper mould fixed plate 7, described cope match-plate pattern 3 and last core 4 are formed patrix, described lower bolster 1 and described core down 5 are formed counterdie, described patrix and described counterdie surround shaping mold cavity 8, and shaping mold cavity has hot flow path to be communicated with it.Described lower bolster 1 one sides also are provided with the ejecting mechanism that is used for goods are ejected core that driven by injection machine, and this ejecting mechanism comprises top board 9 that is subjected to the injection machine driving and the push rod of being located on the described top board 9 10, and described push rod 10 is towards described shaping mold cavity.
The described whole core of going up core 4 and described core down 5 cooperation composition S shapes, describedly go up core 4 and be fixed on the top rotary table, described core 5 down is fixed on the lower rotary table, described cope match-plate pattern 3 is provided with cylinder, described top rotary table is set in described going up on the cylinder rotationally, described lower bolster 1 is provided with down cylinder, and described lower rotary table is set on the described cylinder down rotationally.
The present invention also comprises upper mould oil cylinder and lower mold oil cylinder 11, the knock-pin of described upper mould oil cylinder and first backstay are affixed, first draw-in groove is arranged on the described cope match-plate pattern, described first backstay is over against described first draw-in groove, the knock-pin of described lower mold oil cylinder 11 and second backstay 12 are affixed, on the described lower bolster 1 second draw-in groove is arranged, described second backstay 12 is over against described second draw-in groove.
During injection moulding, the mould clamping is on injection machine, and molten plastic is injected in the shaping mold cavity, and in the chamber cooling and shaping.In the die sinking process, at first lower mold oil cylinder 11 actions snap in second backstay 12 in second draw-in groove, make lower bolster 1 location, the upper mould oil cylinder action withdraws from first backstay from first draw-in groove, be accompanied by and draw flitch 2 and cope match-plate pattern 3 to separate, pull out from sprue to guarantee stub bar, follow cope match-plate pattern 3, lower bolster 1 slowly separates, rely on the withdrawing power of die sinking this moment, makes core 4 rotations, thereby guarantee that plastic breaks away from patrix, up to cope match-plate pattern 3, after lower bolster 1 separates fully, lower mold oil cylinder 11 actions withdraw from second backstay from second draw-in groove, and the upper mould oil cylinder action snaps in first backstay in first draw-in groove, then by injection machine top board 9 is ejected, by push rod 10 goods are ejected, rely on ejecting force, following core 5 rotations are deviate from from counterdie until plastic.Matched moulds and begin a new injection cycle more afterwards.
