Abstract
The invention belongs to mould technical field, it is related to the engine rocker room mould with blind riser, including preceding mould and rear mold, the small die cavity of gas storage connected with die cavity is upwardly extended at more than one the concave up roof for the die cavity that preceding mould and rear mold are formed, venting plug is provided with the small die cavity of gas storage, advantage is：The present invention upwardly extends the small die cavity of the gas storage connected with die cavity in die cavity and forms blind riser at more than one concave up roof, when cast product when, gas in die cavity is pressed into blind riser and forms certain air pressure by casting liquid, the air pressure can be prevented entering the casting liquid at blind riser, there is insulation effect again, prevent the uneven necking of product, venting plug can ensure that the gas in the small die cavity of gas storage will not be pressed into the product of casting and form casting flaw, the structure of the present invention is simple, energy-saving effect is notable, it is easy to use, suitable for polytype casting die.
Description
Technical field
The invention belongs to mould technical field, refers in particular to the engine rocker room mould with blind riser.
Background technology
At present, rising head is set typically in casting mould die cavity at more than one concave up roof, when casting liquid is from emitting
Mouth then thinks that casting liquid is full after outwards overflowing, stopping casting, so, has more casting liquid for more rising head and notes
Enter, form substantial amounts of casting liquid injection rising head and form useless casting liquid, waste the energy.
The content of the invention
It is an object of the invention to provide a kind of energy conservation casting die with blind riser.
The object of the present invention is achieved like this：
Engine rocker room mould with blind riser, including preceding mould and rear mold, between preceding mould and rear mold formed into
The die cavity of h type engine h rocker arm chamber, the gas storage connected with die cavity is upwardly extended at more than one concave up roof in die cavity
Small die cavity, venting plug is provided with the small die cavity of gas storage.
The small head height of die cavity one of above-mentioned gas storage, a high die cavity of low formation and low die cavity, described venting plug are arranged on low
On the roof of die cavity.
Above-mentioned venting plug is plug screw.
The exhaust hole of up/down perforation is provided with above-mentioned plug screw.
Above-mentioned venting plug is check valve.
Above-mentioned check valve is the adjustable check valve of Opening pressure.
Above-mentioned venting plug is arranged in preceding mould or rear mold.
The side wall of above-mentioned small die cavity is that inwardly receipts form truncate polygonal pyramid body for upside.
Core rod is provided with the die cavity that above-mentioned preceding mould and rear mold are formed.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：
The present invention upwardly extends the small die cavity of the gas storage connected with die cavity in die cavity at more than one concave up roof
Form blind riser, be provided with venting plug on the small die cavity of gas storage, so, when cast product when, liquid of casting is by the gas pressure in die cavity
Enter in blind riser and form certain air pressure, first, the air pressure there can be certain prevention to entering the casting liquid at blind riser
Effect, substantial amounts of casting liquid injection rising head is saved, second, the temperature of the air pressure is higher, the temperature-fall period before casting product die sinking
In there is insulation effect, the bad necking for preventing the ununiform shrinkage of product from being formed, venting plug can ensure in the small die cavity of gas storage
Air pressure can not be too big, form casting flaw in the too big product that can then make gas enter casting, structure of the invention is simple, section
Energy significant effect, it is easy to use, suitable for polytype casting die.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the preceding mould of the present invention.
Fig. 2 is the schematic perspective view of the rear mold of the present invention.
Fig. 3 is the principle schematic diagram of the present invention.
Embodiment
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings, referring to Fig. 1-Fig. 3：
Engine rocker room mould with blind riser, including preceding mould 10 and rear mold 11, preceding mould 10 and rear mold 11 it
Between form the die cavity 20 of shaping engine rocker room, upwardly extended at more than one concave up roof in die cavity 20 and mould
The small die cavity 21 of gas storage that chamber 20 connects, venting plug is provided with the small die cavity 21 of gas storage.
The small head height of die cavity 21 1 of above-mentioned gas storage, one low form high die cavity 22 and low die cavity 23, described venting plug are set
Put on the roof 24 of low die cavity 23.
Above-mentioned venting plug is plug screw 40.
The exhaust hole 25 of up/down perforation is provided with above-mentioned plug screw 40.
Above-mentioned venting plug is check valve 42.
Above-mentioned check valve 42 is the adjustable check valve 42 of Opening pressure, and the elasticity by adjusting spring 41 is used to adjust
The Opening pressure of check valve 42, to adapt to the size and gas storage pressure of the small die cavity 21 of gas storage.
Above-mentioned venting plug is arranged in preceding mould 10 or rear mold 20.
The side wall of above-mentioned small die cavity 21 is that upside is inwardly received and forms truncate polygonal pyramid body, in other words small die cavity 21
Side wall has certain angle (such as angle of 0.5-20 degree or 2-10 degree) with vertical plane, casting during in order to mold
The smooth demoulding of engine rocker room.
Core rod is provided with the die cavity 20 that above-mentioned preceding mould and rear mold are formed.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, all should be covered by within protection scope of the present invention.
