Description
Technical field
The present invention relates to Low Pressure Casting Technology neighborhood, and in particular to a kind of low pressure casting wheel hub dead head automatically removes dress
Put.
Background technology
Wheel hub processing includes many processing steps, and a critically important step is exactly aluminium alloy solution wherein in casting
It is poured into mould, is taken out after shaping, dead head can be formed at die casting mouth, it is necessary to subsequently be carried out through lathe at spot facing
Reason.At present, the mode that dead head removes has two kinds：Dead head is removed first, being bored with single-axis drilling machine：This mode need to put into single shaft
Drilling machine, dead head process is completed with four cover dies and a staff；Second, remove dead head with perforating press punching：It is this
Mode need to put into perforating press, and dead head process is completed with six to eight cover dies and a staff；It is each that drilling is compared in punching
There is shortcoming：Drilling efficiency is lower than punching, and punching has the presence that hub extrusion deforms, deflection when especially punching section thickness is exceeded
It is more apparent, or even cause the positive facial disfigurement of wheel hub to scrap, and both all need to be equipped with special equipment and manpower is completed, input cost
It is high, and dead head operation is removed as an independent procedure, overall processing efficiency is influenceed, is unfavorable for mass production.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of low pressure casting wheel hub dead head to automatically remove device.
Technical solution of the present invention is as follows：
A kind of low pressure casting wheel hub dead head automatically removes device, including upper mould, Bian Mo, lower mould, wheel hub die cavity, the first oil pressure
Cylinder, the second oil hydraulic cylinder, high pressure form passage, aluminium liquid inlet and sprue gate, and the sprue gate is located at the center of lower mould, the aluminium
Liquid inlet is located at the bottom of lower mould, and it forms passage by high pressure and connected with sprue gate, and the high pressure is formed in passage and is provided with
Pressurizing piston, the pressurizing piston are fixed on the axostylus axostyle of the first oil hydraulic cylinder, and first oil hydraulic cylinder is fixed on lower mould, described
Second oil hydraulic cylinder is fixed on the center of mould, its axostylus axostyle can straight down activity pass through upper mould center, the end of its axostylus axostyle
Head is fixed with dead head knock-pin, and the center of the side mould is provided with centre bore, and the centre bore passes through wheel hub die cavity and sprue gate
It is connected, the size of the centre bore is consistent with the size at sprue gate, in the presence of the second oil hydraulic cylinder axostylus axostyle, the dead head
Knock-pin can pass through centre bore, sprue gate to enter high pressure just and be formed in passage, and it is logical that dead head discharge is additionally provided with the lower mould
Road, the dead head passing away form passage with high pressure by control valve and connected, and control valve are opened, in the first oil hydraulic cylinder axostylus axostyle
In the presence of, the pressurizing piston may pass through high pressure formation passage and enter dead head passing away.
The beneficial effects of the present invention are：By setting up dead head knock-pin, second on existing low-pressure die casting plant
The dead head of the compositions such as oil hydraulic cylinder, dead head passing away automatically removes device, and utilizes the structure of existing low-pressure die casting plant
Feature, dead head can directly be removed in wheel hub foundry production, compared with prior art, reduce production process, saved
Human cost and material resources cost, improve yield and efficiency.

Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
Refering to Fig. 1, a kind of low pressure casting wheel hub dead head automatically removes device, including upper mould 8, side mould 12, lower mould 13, wheel
Hub die cavity 11, the first oil hydraulic cylinder 1, the second oil hydraulic cylinder 10, high pressure form passage 4, aluminium liquid inlet 3 and sprue gate 5, the cast
Mouth 5 is located at the center of lower mould 13, and the aluminium liquid inlet 3 is located at the bottom of lower mould 13, and it passes through high pressure and forms passage 4 and cast
Mouth 5 connects, and the high pressure forms in passage 4 and is provided with pressurizing piston 2, and the pressurizing piston 2 is fixed on the axostylus axostyle of the first oil hydraulic cylinder 1
On, first oil hydraulic cylinder 1 is fixed on lower mould 13, and second oil hydraulic cylinder 10 is fixed on the center of mould 8, its axostylus axostyle
Can activity straight down pass through the center of upper mould 8, the termination of its axostylus axostyle is fixed with dead head knock-pin 9, in the side mould 12
The heart is provided with centre bore, and the centre bore is connected by wheel hub die cavity 11 with sprue gate 5, the size of the centre bore and sprue gate
5 size is consistent, and in the presence of the axostylus axostyle of the second oil hydraulic cylinder 10, the dead head knock-pin 9 can pass through centre bore, cast just
