Description
Technical field
The present invention relates to a kind of silicon rubber injection molding, particularly a kind of silicon rubber insulator injection molding stripper apparatus.
Background technology
The existing silicon rubber insulator for power transmission and transformation line is mostly injection moulding.Crunch during due to injection, after formed product, and between die cavity, push very tightly, but because the time of compound inslation forming technique application is not long, current one-time formed insulator product length is generally no more than 1.5m, this product is because length is shorter, and the required dynamics of break away from moulds is still in manpower scope in one's power, so be all by manually carrying out at present by product break away from moulds.Development along with high pressure and extra-high voltage electric transmission and transformation industry, the demand of high-tension insulator product is increasing, length also increases gradually, correspondingly large-scale rubber injection moulding machine also starts application, for large-scale like this product, then adopt the artificial demoulding very difficult, not only labour intensity is large, production efficiency is low, and likely product is caused the quality problems such as scratch, fracture during hand ejection.
For above-mentioned technical problem, be still necessary to invent a kind of device that carries out the demoulding after silicon rubber insulator injection moulding that facilitates.
Summary of the invention
The present invention, in order to overcome prior art defect, has invented a kind of silicon rubber insulator injection molding stripper apparatus, adopts automatic demoulding, enhances productivity, and while avoiding hand ejection, product is caused the quality problems such as scratch, fracture.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
An injection molding stripper apparatus, it comprises:
Moving platen;
Lower bolster, it is fixedly installed in the upper end of described moving platen;
Lower hot plate, it is fixedly installed between described moving platen and described lower bolster;
Plug, it is positioned in described lower bolster die cavity;
Wherein:
Loose plug, it is arranged in the die cavity of described lower bolster in the mode of can slide up and down, and the corresponding so that die cavity of itself and described lower bolster of the shape of the shape of its upper end and described lower bolster die cavity combines as the die cavity of product, and it is at least three and along the axial directional distribution of described lower bolster die cavity;
Driving mechanism, it is fixed on described moving platen, and it is connected to drive described loose plug to slide up and down with described loose plug.
Preferably, described driving mechanism is hydraulic jack, and described in each loose plug correspondence is by a described hydraulic oil cylinder driving, and the cylinder body of described oil cylinder is fixedly installed on described moving platen, and described cylinder piston rod is fixedly connected with the lower end of described loose plug through described lower hot plate.
Preferably, the metal handle lower end at described plug two ends is connected with a hydraulic jack respectively.
Preferably, described loose plug is 6.
Preferably, described loose plug is symmetrically distributed in the axial both sides of described lower bolster die cavity.
The present invention compared with prior art, has following beneficial effect:
A kind of silicon rubber insulator injection molding of the present invention stripper apparatus lower bolster die cavity bilateral symmetry a plurality of loose plugs that drive with hydraulic jack are set, and plug lower end correspondence is provided with hydraulic jack, and the upper end face of loose plug is corresponding with lower bolster mold cavity surface, and by automatic control system, the action of oil cylinder is controlled, the loose plug jack-up that can make progress is regained again asynchronously, being convenient to product first gets loose with lower bolster die cavity, can synchronously make progress jack-up to lift product again, reach demoulding object, production efficiency is high, and not fragile product.
Accompanying drawing explanation
Accompanying drawing 1 is the drive mechanism schematic diagram of a kind of silicon rubber insulator injection molding of the present invention stripper apparatus.
Accompanying drawing 2 is the top view of accompanying drawing 1.
Wherein: 1-8, demoulding oil jar; 9-14, loose plug; 15, plug; 16, lower bolster; 17, heating plate; 18, moving platen.
The specific embodiment
Referring to accompanying drawing and in conjunction with the specific embodiment, further describe the present invention, to make those skilled in the art can implement according to this with reference to description word, but be to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side " and " right side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
Embodiment
As depicted in figs. 1 and 2, a kind of silicon rubber insulator injection molding stripper apparatus, it is by lower bolster 16, lower hot plate 17, moving platen 18, plug 15, demoulding oil jar 1-8 and loose plug 9-14 form, wherein lower bolster 16 is fixed on moving platen 18 upper ends, and be provided with lower hot plate 17 between the two, plug 15 correspondences are positioned in the die cavity of lower bolster 16, loose plug 9-14 is arranged at the lower end of the die cavity of lower bolster 16 from left to right in the mode of can slide up and down, loose plug 9-14 is symmetrically distributed in the lower bolster left and right sides, and the upper end of loose plug 9-14 is extended in the die cavity of lower bolster 16, and the shape of its upper end is corresponding with the mold cavity surface shape institute of lower bolster 16, loose plug 9-14 end by jack-up before, the mold cavity surface of its upper end and lower bolster 16 combines and forms a complete product mold die cavity, and loose plug 9-14 lower end is connected with the piston rod of demoulding oil jar 2-7 successively, the piston rod correspondence of demoulding oil jar 1 is arranged at the metal handle lower end of plug 15 left ends, demoulding oil jar 8 correspondences are arranged at the metal handle lower end of plug 15 right-hand members, and demoulding oil jar 1-8 is hydraulic jack, and the cylinder body of demoulding oil jar 1-8 is fixedly mounted on moving platen 18, the piston rod of demoulding oil jar 2-7 is connected with loose plug 9-14 lower end through lower hot plate 17 is corresponding.
