Description of reference numerals: ejecting mechanism 1; Penetrate board fixed head 2; Oil pressure plate 3; Oil hydraulic cylinder 30; First oil hydraulic cylinder 31; Second oil hydraulic cylinder 32; The 3rd oil hydraulic cylinder 33; Penetrate pressing mold tool 4.
The specific embodiment
The preferred embodiment of the utility model is to disclose a kind of ejecting mechanism, is to be applicable to that plastics penetrate the ejecting mechanism of pressing mold tool.
See also shown in Figure 1ly, the composition of this ejecting mechanism 1 comprises: one penetrates a board fixed head 2 and an oil pressure plate 3; Particularly be laid with the oil hydraulic cylinder 30 of multiple and a plurality of difference in functionalitys on this oil pressure plate 3, and on this oil pressure plate 3, the setting of penetrating pressing mold tool 4 be provided.
As shown in Figure 2; The kind and the function of this oil hydraulic cylinder 30 include at least: first oil hydraulic cylinder 31; Can select at least more than one, and be provided with, penetrate the cut-out of article shaped and the purposes that ejects in the pressing mold tool 4 to provide to penetrate corresponding to the running channel of penetrating the pressing mold tool and die cavity junction; Second oil hydraulic cylinder 32 can be selected at least more than one, and is provided with corresponding to the cast gate place of penetrating pressing mold tool 4, ejects the purposes of ejection formation thing so that demoulding to be provided; And the 3rd oil hydraulic cylinder 33, can select to be laid in around the whole die cavity of penetrating pressing mold tool 4, penetrate the compression purposes of pressing mold tool 4 when the ejection formation to provide.
Above-mentioned first oil hydraulic cylinder 31, second oil hydraulic cylinder 32 and the 3rd oil hydraulic cylinder 33 are except be laid in the position on the oil pressure plate 3 simultaneously shown in the drawing of present embodiment; The function that it provided not is to change; Because of the stream that all oil hydraulic cylinders 30 all utilize pipeline to link fluid is done centralized management; So on reality is used, can do optionally installing according to user's demand; And installation position is non-to only limit to the kenel shown in the drawing, also can penetrate pressing mold tool 4 and different ejection formation thing is optionally replaced function with corresponding oil hydraulic cylinder 30 voluntarily to different.
According to above-mentioned ejecting mechanism 1 on the implementation, it is fixing and settle appropriately to penetrate board fixed head 2, will penetrate pressing mold tool 4 simultaneously and be placed on the oil pressure plate 3, relies on the compression that pushes against of most the 3rd oil hydraulic cylinders 33, penetrates preparation and accomplish; After the ejection formation process finishes; The ejection formation thing is molded to finish but before die sinking is taken out, utilize this moment first oil hydraulic cylinder 31 of this ejecting mechanism 1 be provided in to penetrate in the pressing mold tool cut-out with eject purposes, can be earlier with the aggregate separated of ejection formation thing and other running channel, cast gate etc.; Then; When after die sinking, needing to take out the ejection formation thing, can eject this ejection formation thing when utilizing second oil hydraulic cylinder 32 that demoulding is provided again, reach the effect of conveniently getting thing.
Please consulting shown in Figure 3ly again, is that another implements kenel sketch map; Wherein drawing left side be the board fixation side of ejaculator, the figure right side of face be movable side also device ejecting mechanism 1 is arranged, middle then be fixed with a cave pattern penetrate pressing mold tool 4; In the use; When the drawing left side is injected in the hot gluse size; The ejaculation pressure of ejaculator can make penetrates pressing mold tool 4 and board is monolateral stressed, and produces energy imbalance, at this moment; Through being fit to of position on the oil pressure plate 3 of ejecting mechanism 1, fixedly effectiveness of required compression is provided with upper hydraulic cylinder 30 unified startups; Thus, just can rely on the oil hydraulic cylinder 30 of ejecting mechanism 1 to provide the auxiliary of ejaculation process to eject, keep the fixing and balance of penetrating pressing mold tool 4, and then reduce the disqualification rate of ejection formation thing.
Can know by above explanation; The utility model will be penetrated the pressing mold tool and in the ejection formation process, can use the multiple difference in functionality that utilizes oil hydraulic cylinder to reach and be integrated on the oil pressure plate; And utilize pipeline to connect all fluid of laying the most oil hydraulic cylinders on it and supply with, and unified centralized Control and do the appointed function action according to all oil hydraulic cylinders of user demand control reaches required compression, ejects, effect such as mould internal cutting off; Make penetrate the pressing mold tool can be more efficient on volume production, to promote production capacity and tool economy.
More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence, but all will fall within the protection domain of the utility model.
