Embodiment 1 is that a kind of aluminium alloy compression casting system of the application is vertical with reference to shown in attached drawing 1, attached drawing 2, attached drawing 3 and attached drawing 4
Body structure is unfolded view, cross-sectional view 1 and cross-sectional view 2, the type chamber of the aluminium alloy compression casting system mainly by upper mold 1, right mould tool 2,
Left mold 3, axle sleeve 4, piston pin 5, type core retainer plate 8 and type core 9 are constituted, and wherein upper mold 1 is by upper mold main body 1a, exhaust column 1b
It is constituted with pressing plate 1c, type core 9 is made of middle part type core 9a, first side type core 9b, second side type core 9c and sliding slot 9d.
The top of the middle part type core 9a and the bottom of exhaust column 1b are equipped with metal exhaust net, its role is to: first is that
When casting of molten metal, the intracavitary air of discharge type；Second is that during molten metal is cooled and shaped, due to containing inside molten metal
Perhaps other substances will cause the cast(ing) surface after cooling and shaping by thermogenetic gas to a certain amount of gas or is produced from inside
Angry hole, and it is equipped with metal exhaust net in the bottom at the top of middle part type core 9a and exhaust column 1b, it can make in molten metal
Gas is discharged under the pressure of die casting by metal exhaust net, and the generation of stomata is reduced, and improves the quality of casting finished products.
Piston pin 5 is inserts, and according to the requirement of different product, the inserts that can design different structure is mounted on right mould tool
3 and left mold 2 on, meet product part property requirement.
As shown in Fig. 5, the middle part type front and rear sides the core 9a face is equipped with sliding slot 9d, is equipped with guide pad 10 in sliding slot 9d,
And sliding slot 9d is that inner buckle structure is connect with guide pad 10, guide pad 10 can only be sliding from the opening of the sliding slot 9d of the middle part bottom type core 9a
Enter inside sliding slot 9d.Second side type core 9c medial surface bottom is connect with guide pad 10, and second side type core 9c can be in
Side slides up and down before and after portion type core 9a.
The angle of the middle part type front and rear sides the core 9a face and bottom surface is 84 °, and the angle and the second side type core
9c medial surface and the angle of bottom surface are complementary relationship；The angle of the middle part type core 9a left and right sides and bottom surface is 89 °, and should
Angle and the first side type core 9b medial surface and the angle of bottom surface are complementary relationship.
Shown in appended Fig. 2 and attached drawing 6, the middle part type bottom core 9a is equipped with middle part type core support 7, and the middle part type core
9a and middle part type core support 7 are attached by connecting shaft 11 and pin；7 front and rear sides of middle part type core support are equipped with circular hole,
And circular hole tilts inwardly, with the inside angle of bottom surface and the angle phase in the middle part type front and rear sides the core 9a face and bottom surface
Deng equipped with spring 12 inside circular hole；The circular hole bottom of middle part type core support 7, other end connection are fixed in described 12 one end of spring
The bottom surface of second side type core 9c.
As shown in Fig. 5, U-shaped protrusion, and the middle part type core 9a are equipped at the top of the first side type core 9b medial surface
It may make equipped with the groove to match by U-shaped protrusion and the groove to match at the top of the left and right side Xing Xin9c of second side
Middle part type core 9a, first side type core 9b and second side type core 9c when assembling can automatic aligning, guarantee accurate positioning.
Press casting procedure is as follows: be first molten metal is poured into from 14 high-voltage high-speed of sprue gate by automatic pouring device, then by
Injection punch head moves downward, and pushes molten metal, molten metal is by neck road 15, the type chamber being pushed into grinding tool hole 13；Molten metal exists
Pressure acts on lower cooled and solidified.
After product cooling and shaping, left mold (3), right mould tool (2) and upper mold (1) etc. component are first dismantled；Then in
Bu Xing core support 7 moves down, and middle part type core 9a follows middle part type core support 7 to synchronize together and moves down, but due to product cavity body
For concave inward structure, second side type core 9c can not follow middle part type core 9a synchronous with middle part type core support 7 to moving down；Due to middle part
The front and rear sides type core 9a are inward-facing to be rolled tiltedly, and guide pad 10 and sliding slot 9d are that internal buckle is connect, thus work as middle part type core 9a move down and
When second side type core 9c can not be moved down, the second side type core 9c on front and back both sides can be because of the inside sidesway of constraint of sliding slot 9d
It is dynamic, and then smoothly demould；Second side type core 9c moves inward, and is no longer influenced by the constraint of product concave inward structure, at this time due to
Second side type core 9c is connect by spring 12 with middle part type core support 7, and 12 meeting of elastic force of spring 12 is so that second side type core
9c is moved down.
After middle part type core 9a and second side type core 9c demoulding, manipulator can control the inside sidesway of first side type core 9b
Dynamic, so that second side type core 9c is moved still further below not by the constraint of product concave inward structure and piston pin 5, type core 9 is demoulded at this time
It completes.
The above are only specific embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
