Description
Technical field
The present invention relates to injection moulding or die-casting and molding technology field, particularly relate to a kind of deformation compensating mechanism on injection machine or die casting machine rack.
Background technology
When utilizing injection moulding or die-casting and molding technology to produce product, first need dynamic model and cover half matched moulds to form product die cavity, then melt raw material is injected die cavity, and make formed product under a certain pressure.In the process of injecting raw material or pressing formation; due to the effect of pressure; dynamic model and cover half can produce certain distortion; this distortion directly causes die cavity original-shape to change; and finally cause injection moulding or die-cast product shape to change; or even produce underproof product, have a strong impact on production efficiency, increase production cost.Person skilled payes attention to the problem that solution product is out of shape in injection moulding or die cast process especially for this reason.
The problem that deformation occurs in injection moulding process for traditional solution injection moulding or die-cast product mainly concentrate on how to compensate dynamic, the deformation that cover half occurs when pressurized, as Chinese patent document CN1840311A discloses a kind of injection machine with a basic C-form stand, a side leg of this injection molding machine frame is fixed with cover half, its another side leg is fixed with closing device, this closing device can promote dynamic model close to or away from cover half by hinged component, hinged component is connected with dynamic model by two supporting surfaces spaced apart from each other, and two supporting surfaces are distributed in above and below the horizontal centre plane of dynamic model.In the process of injection moulding; due to the effect of injection pressure, dynamic model and cover half can produce certain deformation, and this deformation is delivered on hinged component by two gripper shoes spaced apart from each other; hinged component absorbs a part of deformation, makes dynamic model and the quiet mould basic keeping parallelism when clossing pressure.When less injection moulding power, above-mentioned compensation arrangement may be used for the deformation compensating dynamic model and cover half, reduces the change of mold cavity.Time but injection pressure is larger, the pressure that dynamic model and cover half are subject to be passed to support described dynamic model and cover half frame on, because frame leg fixes on the ground, above-mentioned injection pressure makes the two ends, left and right on the upside of frame be subject to along the active force outside the sensing of frame length direction respectively, now will with the leg fixed on the ground of frame for fulcrum, the right-hand member of support is made to have torsion along clockwise direction, support left end then has anticlockwise torsion, and then make the side plate of the horizontally set being positioned at central rack produce a distortion of upwards arching upward, the part being positioned at below side plate center line then can produce a distortion extruded to centre by two ends.This deformation exacerbates the relative deformation between dynamic, cover half, thus has had a strong impact on the shape of injecting products.And frame itself occur deformation on the impact of product often ignore by technical staff, so, product quality comparatively large for some injection pressures requires only to design higher product deformation compensating mechanism from dynamic model or cover half and obviously can not meet the demands.
