Beneficial effect of the present invention is: aluminium alloy injection molding raw material of aluminum alloy (bar sheet) is prepared into liquid phase from solid phase at same closed environment by aluminium alloy injection (mo(u)lding) machine and is injected in a kind of mould shaping mould cavity, present invention incorporates the feature of plastic injection mould and metal die-casting mold, the process of injection molding of aluminium alloy injection molding is airtight, gas can not be infiltrated, the most important thing is that the humidity control system of aluminium alloy Injection Mould Design of the present invention can avoid mold temperature too high or too low, improve the mobility of aluminium alloy solution, solve the pore of long-standing problem aluminium alloy industry, the problem such as fire check and misrun.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figure 1, the aluminium alloy injection molding that the present invention proposes comprises: fixed half and moving half, and described cover half is made up of top clamping plate 1 and die 2 fixed thereon; Described dynamic model comprises moving platen 3 and punch 4 fixed thereon, and described die and punch form injection cavity; Pass through guide plate 6, cushion block 7 and Bottom clamp plate 8 that screw rod 5 is connected with moving platen 3 successively; Be arranged on push rod 11 on Bottom clamp plate and release link 12 by push pedal 9 and fixed head 10, described push rod 11 runs through guide plate 6 and punch 4 successively, and described release link 12 runs through guide plate 6 and moving platen 3 successively; The guide pillar 13 through moving platen and die is provided with between described guide plate 6 and top clamping plate 1; Described top clamping plate 1 is provided with and the cast gate 14 injected cavity and be communicated with, and described die is provided with humidity control system.
Humidity control system comprises: be provided with the heating system of resistance wire 15 and offer the cooling system of cooling-water duct 16; Aluminium alloy injection molding is also provided with and the exhaust passage of injecting cavity and being communicated with; Cast gate 14 is provided with detachable sprue bush.
Aluminium alloy injection molding is made up of dynamic model and cover half two parts, and wherein cover half part is arranged on the fixed form of aluminium alloy injection (mo(u)lding) machine, and dynamic model part is arranged on aluminium alloy injection (mo(u)lding) machine moving die plate.In process of injection molding, dynamic model part is moved together along with the clamping in aluminium alloy injection moulding; injection running gate system die cavity is closed into by moving platen 3, punch 4 and die 2; aluminium alloy solution enters die cavity from aluminium alloy injection (mo(u)lding) machine nozzle through cast gate 14; after cooling die sinking; dynamic model part is separated with cover half part, and push pedal 9 promotes push rod and ejected from die cavity by aluminum component.As shown in Figure 1, different according to each several part role on mould, injection molding can be divided into following components to aluminium alloy injection molding general structure:
(1) parts are supported:
Be used for fixing or support forming parts and aforementioned each several part mechanism parts are installed.Support parts and fit together the basic framework that can form injection molding, the top clamping plate 1 as shown in the figure, Bottom clamp plate 8 and cushion block 7.
(2) running gate system:
The passage that molten aluminium alloy enters mold cavity institute flow path from injection machine injection nozzle claims running gate system.Running gate system is by sprue, and runner, cast gate and cold slug well four part form.As shown in Figure 1, the cast gate 14 on top clamping plate 1 forms running gate system passage of the present invention with die 2.
(3) forming unit:
Moulding section is made up of moving platen 3, punch 4 and die 2.Punch 4 forms the inner surface configuration of alloy product.Die 2 forms the outer surface form of alloy product.
(4) pilot unit:
Correct matched moulds for guaranteeing to move, between cover half, and alloy product dimensional accuracy.Pilot unit is provided with between dynamic, cover half.Guide pillar 13 one end of pilot unit is arranged on moving platen 3, and remainder can move along die locating hole 17, thus is folding mould guiding; Pilot unit also comprises guide plate 6, and guide plate 6 can ensure ejecting mechanism stable movement.
(5) ejector unit:
The device released from mould by alloy product after ejector unit refers to mould somatotype, as shown in Figure 1, ejector unit comprises: the ejector pin retaining plate 10 on the right side of push pedal 9, push pedal and the push rod 11 be fixed on ejector pin retaining plate.
(6) humidity control system:
For meeting the requirement of injection technique to mold temperature, ensure to control the mobility that aluminium alloy solution keeps best in running gate system to mold temperature.So mould is provided with humidity control system.Humidity control system comprises: be provided with the heating system of resistive heater 15 and offer the cooling system of cooling-water duct 16.
