Abstract

The utility model relates to a die for aluminum shells, comprising an angle pin, a core-loosing slide block, a fixed core, a movable core, opposite fixed and movable dies, a casting gating system arranged on a parting surface, wherein the core-loosing slide block is arranged on the angle pin and is in a U-shape, two 'straight lines' of the 'U' shape are respectively two cores in different shapes, and the angle pin is fixed on a fixed die bolster and forms an angle of 45 degrees with the fixed die bolster; the movement velocities of the core-loosing slide block along the horizontal direction and the vertical direction are same; and the core-loosing slide block can slide along the angle pin. The die has the advantages of simple structure, synchronous loosing of the cores in different shapes arranged on the core-loosing slide block, cost conservation, guarantee of the simultaneity of movement and labor conservation. The angle of 45 degrees formed between the angle pin and the fixed die bolster ensures that the core-loosing slide block moves at the same speed along the horizontal direction and the vertical direction, also ensures the movement simultaneity of the core-loosing slide block and the movable die part along the horizontal direction and avoids the interference of the movable die and the core-loosing slide block during the movement of the movable die.

Description

The aluminum hull mould

Technical field

The utility model relates to a kind of aluminium alloy casting, relates in particular to a kind of aluminum hull mould.

Background technology

Aluminium alloy is our common used material in metal casting, its good fluidity, and moulding is fast, good heat-transfer, cutting has easily now obtained to use widely.

At present, many producers are when making aluminum alloy die-casting die, because the structure to product is considered comprehensive not to the utmost, caused the die cost height, the unreasonable structure of die casting design, there is cold shut in the product of die cast, owe casting, defectives such as shrinkage porosite, shrinkage cavity, distortion have caused the yield rate of product low, product cost increase etc.

Summary of the invention

The utility model mainly is to solve the existing in prior technology mould structure to design unreasonable, casting defect is many, production cost high-technology problem, provide a kind of project organization reasonable, can reduce the die casting defective, improve the Forming Quality of die casting, finished product rate height, the aluminum alloy die-casting die of advantages such as low production cost.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of aluminum hull mould, comprise the taper pin axle, the slide block of loosing core, the cover half core, dynamic mould core, corresponding fixed half and moving half, and be arranged on the casting moulding system of die joint, the slide block of loosing core is arranged on the bearing pin, and the slide block of loosing core is " U " shape, and two " straight lines " of " U " shape are respectively two difform cores, the taper pin axle is fixed on the cover half cage plate, becomes 45 degree with the cover half cage plate;

As preferably, the described slide block of loosing core is identical with the vertical direction movement velocity in the horizontal direction;

As preferably, the described slide block of loosing core can slide along the taper pin axle.

Therefore, the utlity model has: 1. rational in infrastructure, two difform cores are set on the slide block of loosing core, can loose core simultaneously, saved cost, guaranteed the simultaneity of motion, saved external force; 2. the taper pin axle becomes the miter angle setting with the cover half cage plate, and the slide block horizontal direction that guaranteed to loose core is directly identical with vertical direction speed, and the synchronism of also guaranteed simultaneously to loose core slide block and the motion of dynamic model part of horizontal is during the dynamic model of avoiding motion and the interference of the slide block of loosing core.

Accompanying drawing 2 is mould cross-sectional view of the present utility model;

Accompanying drawing 3 is mould cross-sectional view of the present utility model.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as Fig. 1, shown in 2,3, the utility model comprises taper pin axle 2, the slide block 1 of loosing core, cover half core 4, cover half cage plate 5, dynamic mould core 6, dynamic model cage plate 7, cushion block 8, ejecting mechanism 9, moving clamping plate 10 and be arranged on casting moulding system on the die joint.Moving clamping plate 10 and dynamic model cage plate are provided with cushion block 8 between about in the of 7, by screw, they are fixed together.10 plates link together at the bottom of dynamic model cage plate 7, cushion block 8 and the dynamic model, have formed the space of a hollow, are provided with ejecting mechanism 9 in it.Ejecting mechanism 9 comprises push pedal, push pedal fixed head, guide pillar, guide pin bushing, core bar and push rod.Ejecting mechanism 9 mo(u)ld top half core bars the moulding that can help dynamic mould core 6 is set.Guide pillar, guide pin bushing, push rod can eject the dynamic model die cavity with the foundry goods 3 of moulding under the drive of push pedal and push pedal fixed head.Dynamic model cage plate 5 is provided with dynamic mould core 6 and taper pin axis hole.Corresponding with dynamic mould core 6 is cover half core 4.Cover half core 4 is fixed on the cover half cage plate 5.Also be provided with taper pin axle 2 on the cover half cage plate 5, become miter angle between taper pin axle 2 and the cover half cage plate 5.Be provided with the slide block 1 of loosing core between dynamic model cage plate 7 and the cover half cage plate 5, the slide block 1 of loosing core is " U " shape, and two " straight lines " of " U " shape are respectively two difform cores.The setting of this structure has guaranteed that two difform cores can loose core simultaneously, has saved cost, has guaranteed the simultaneity of motion, has saved external force.5 one-tenth miter angle settings of taper pin axle 2 and cover half cage plate, the slide block 1 of loosing core slides along the taper pin axle, slide block 1 horizontal direction that guaranteed to loose core is directly identical with vertical direction speed, the synchronism of also guaranteed simultaneously to loose core slide block 1 and the motion of dynamic model part of horizontal, during the dynamic model of avoiding motion with the interference of the slide block of loosing core.

During the aluminum hull mold work, the cover half partial fixing is motionless, and the dynamic model part is partly being drawn close to cover half under the casting machine effect, with the cover half matched moulds.The slide block 1 of loosing core also puts in place simultaneously, has formed die cavity.After matched moulds finishes, molten aluminium alloy is pressed into die cavity along cast gate 11, liquid is full of die cavity rapidly.After cast finished, foundry goods 3 formed, and the dynamic model part is separated with cover half under external force, and the slide block 1 of loosing core moves along taper pin axle 2 and dynamic model level of synchronization.After moving to default distance, the stop motion of dynamic model part, the slide block 1 of loosing core also breaks away from foundry goods 3 fully, and promote ejecting mechanism 9 this moment, and foundry goods 3 is pushed away the dynamic model die cavity, and foundry goods 3 is removed.Dynamic model carries out next matched moulds process under external force.

This Mould design, simple to operate, moulding is easy, and is rational in infrastructure, saved manufacturing cost, and the quality of foundry goods also obtained very big improvement, helps applying.
