Abstract
The utility model belongs to molding die technical field, it is related to the engine rocker room molding die with blind riser, including preceding mould and rear mold, the small die cavity of gas storage being connected to 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, it is provided with venting plug on the small die cavity of gas storage, advantage is：The utility model upwardly extends the small die cavity of the gas storage being connected to 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 prevent the casting liquid entered at blind riser, there is insulation effect again, prevent the uneven necking of product, venting plug can guarantee 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 utility model has the advantages of simple structure, energy-saving effect is significant, it is easy to use, suitable for a plurality of types of casting dies.
Description
Technical field
The utility model belongs to molding die technical field, refers in particular to the engine rocker room molding die with blind riser.
Background technique
Currently, riser is arranged at more than one concave up roof generally in casting mould die cavity, when casting liquid is from emitting
Mouth then thinks that casting liquid has been expired after overflowing outward, stop casting, and infuses in this way, having more casting liquid for more riser
Enter, forms a large amount of casting liquid injection riser and form useless casting liquid, waste of energy.
Summary of the invention
The purpose of the utility model is to provide a kind of energy conservation casting die with blind riser.
What the purpose of this utility model was realized in：
Engine rocker room molding die with blind riser, including preceding mould and rear mold, between preceding mould and rear mold formed at
The die cavity of h type engine h rocker arm chamber upwardly extends the gas storage being connected to die cavity at more than one concave up roof in die cavity
Small die cavity is provided with venting plug on the small die cavity of gas storage.
Small one head height of die cavity of above-mentioned gas storage, a high die cavity of low formation and low die cavity, the venting plug are arranged low
On the roof of die cavity.
Above-mentioned venting plug is plug screw.
Exhaust hole up and down is provided on above-mentioned plug screw.
Above-mentioned venting plug is check valve.
Above-mentioned check valve is the adjustable check valve of cracking pressure.
Above-mentioned venting plug is arranged on 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.
Mold core is provided in the die cavity that above-mentioned preceding mould and rear mold are formed.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
It is small that the utility model upwardly extends the gas storage being connected to die cavity at more than one concave up roof in die cavity
Die cavity forms blind riser, is provided with venting plug on the small die cavity of gas storage, in this way, when cast product when, liquid of casting is by the gas in die cavity
Body is pressed into blind riser and is formed certain air pressure, first is that the air pressure can have centainly the casting liquid entered at blind riser
Interception saves a large amount of casting liquid and injects riser, second is that the temperature of the air pressure is higher, the cooling before casting product die sinking
There is insulation effect, the bad necking for preventing the ununiform shrinkage of product from being formed in the process, venting plug can guarantee the small mould of gas storage
Intracavitary air pressure cannot be too big, so that gas is entered greatly and form casting flaw, the knot of the utility model in the product of casting
Structure is simple, and energy-saving effect is significant, easy to use, is suitable for a plurality of types of casting dies.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of the preceding mould of the utility model.
Fig. 2 is the stereoscopic schematic diagram of the rear mold of the utility model.
Fig. 3 is the principle schematic diagram of the utility model.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-Fig. 3：
Engine rocker room molding die 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 molding engine rocker room, upwardly extended at more than one concave up roof in die cavity 20 and mould
The gas storage small die cavity 21 that chamber 20 is connected to is provided with venting plug on the small die cavity 21 of gas storage.
Small 21 1 head height of die cavity of above-mentioned gas storage, one low form high die cavity 22 and low die cavity 23, the venting plug are set
It sets on the roof 24 of low die cavity 23.
Above-mentioned venting plug is plug screw 40.
Exhaust hole 25 up and down is provided on 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 cracking pressure, by adjusting the elasticity of spring 41 for adjusting
The cracking 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 on preceding mould 10 or rear mold 20.
The side wall of above-mentioned small die cavity 21 is that upside inwardly receives 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), casting and forming when in order to be opened with vertical plane
The smooth demoulding of engine rocker room.
Mold core is provided in the die cavity 20 that above-mentioned preceding mould and rear mold are formed.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
