The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

A kind of kirsite subbase die casting is comprised of top clamping plate 3, solid plate, moving platen, dynamic model pressing plate 7, support plate 9, cushion block 10, Bottom clamp plate 14, guide pillar 24, guide pin bushing 23; It is characterized in that: be provided with cover half cage plate 4 on the described cover half, cover half cage plate 4 is connected on the top clamping plate 3 by soket head cap screw 2, top clamping plate 3 is provided with sprue bush 1, sprue bush 1 is embedded on the top clamping plate 3, main core 2 is connected on the top clamping plate 3 by soket head cap screw 30, also be provided with a banking pin 29 on the main core 2, also be provided with small-sized core 27 and guide pillar 24 on the top clamping plate 3, spring knock pin 25, fixed die insert 26 are provided with the cavity that holds fixed die insert 26 on the described top clamping plate 3.

Mould is grouped into by fixed half and moving half two tops, cover half is fixed on compression chamber of die casting machine one side's the top clamping plate 3, it is the arrival end that molten metal begins to enter the compression mod die cavity, there is sprue directly to be connected with nozzle or the pressure chamber of die casting machine on the cover half, dynamic model is fixed on the Bottom clamp plate 14 of die casting machine, with Bottom clamp plate left, move right and separate and close up with cover half, generally loose core and establish in the inner with the foundry goods ejecting mechanism, behind matched moulds, form a cavity that consists of the die casting shape by moving die insert and cavity block.

With die casting or cast clout from mechanism that mould is deviate from, comprise and release part and reset components, such as the push rod among the figure, ejector pin retaining plate and push pedal, simultaneously, for making ejecting mechanism steadily reliable when mobile, self guide elements push pedal guide pillar 23 and ejector guide pillar 14 also are set, for ease of clearing up foreign material or preventing that foreign material from affecting the proper reset of push pedal, also in the push pedal bottom banking pin 29 is set, on foundry goods, have and the inconsistent side opening of release direction, during recessed the or side convex form of side, behind die cast, forming part herein can hinder the release of foundry goods, and transportable side core must be set.Before foundry goods is released, first core is extracted out, after removing obstacles, again die casting is released, during matched moulds, again core is returned to original shaping position.Side core-pulling mechanism adopts Slanted slide block mechanism, and characteristics are compact conformations, and reliable in action is usually used in the side shaping area larger, and side opening, side are recessed more shallow, the situation that required Core-pulling force is little, and angled-lift splits 5 slide guide forms adopt the T-slot slide guide.

Because the package power of fixed mold is larger, during die sinking, angled-lift splits and may be left on the fixed mold gradually, or angled-lift splits is subject to the package power of fixed mold and produces displacement, make casting deformation, should arrange forcing device this moment, angled-lift splits is stably stayed in the dynamic model cage plate after guaranteeing die sinking, and 4 spring spacer pins have been installed in the package power effect of fixed mold, to avoid angled-lift splits to move radially, stay in the dynamic model cage plate mean diameter of coil D=40mm of the spring spacer pin of employing, spring wire diameter d=8mm thereby forcing tiltedly slides, number of active coils n=7, adopting material is silicon-manganese spring steel 60Si2MnA.

Side core-drawing mechanism of slanting sliding block is comprised of angled-lift splits, dynamic model cage plate 6 and push rod 11.The angled-lift splits 5 that is combined into by lobe is embedded in the guide runner of dynamic model cage plate.During matched moulds, the die joint of cover half cage plate 4 contacts with the upper surface of angled-lift splits 5, makes lobe close location in the inclined-plane that angled-lift splits pushes respectively dynamic model cage plate 6.The sealing surface of angled-lift splits 5 each side direction is locked under the effect of die-casting machine die-locking power.After the die sinking, the liftout attachment of die casting machine promotes the ejecting mechanism of mould, drives push rod 11 and promote angled-lift splits 5 to move to stripping direction.On this process, because the guide effect of dynamic model cage plate 6 interior Angle Pin grooves makes angled-lift splits 5 when the promotion die casting travels forward, the downside somatotype that makes progress respectively namely when releasing die casting, is extracted the jog of die casting side out, finishes the side core-pulling action.Mold parting surface has been arranged on foundry goods bottom surface and die cavity inside according to the industrial analysis design of foundry goods with die joint, and molten metal enters from the foundry goods side.In order to prevent molten metal to the impact of core, ingate and foundry goods adopt the connected mode of the existing overlap joint of end, and cross gate adopts T-shaped, and overflow launder is arranged on four jiaos of places, subbase bottom surface, is the symmetric form setting, and the allowance of foundry goods is 0.1mm, and draw taper is 1.5 degree.

Design feature according to foundry goods, adopted the angled-lift splits core-pulling mechanism, it is the splitting mode of two lobe formulas, guide mechanism adopts T-shaped groove, move radially for avoiding angled-lift splits to produce when the die sinking, adopt spring knock pin 25 stably to stay in the dynamic model cage plate 6 with angled-lift splits 5 after guaranteeing die sinking, mould adopts push rod 11 ejecting mechanisms, be provided with several push rods 11, rod diameter 26mm is for preventing ejecting mechanism hyperkinesia in reseting procedure, the movement travel that banking pin guarantees ejecting mechanism is set, and make and respectively release element and be returned to exactly original position, the flexible movements of empirical tests mould open/close mould do not produce interference between part.During use, be contained on the board holddown groove by screw, screw rod and cushion block lock by stationary mould for mould seat board 3, mould Bottom clamp plate 14 is contained on the board holddown groove by screw, screw rod and cushion block lock, drive dynamic model by board and carry out matched moulds, die sinking, cooperated by special-purpose die casting board, simple to operate, safe and reliable, production efficiency is high.
