Description

Bilateral low-pressure casting equipment Technical Field The utility model relates to the field of low-pressure casting, in particular to bilateral low-pressure casting equipment. Background The low pressure casting equipment is injected through the lift pipe, can only carry out the operation through a lift pipe under the general circumstances, and casting efficiency is lower, if through many lift pipes, not only can improve the efficiency to single mould, can also realize injecting simultaneously to a plurality of moulds, but many lift pipes can only inject the same speed yet, hardly control respectively to different service conditions, and in addition can't inject to a lift pipe any more. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide bilateral low-pressure casting equipment, which solves the existing pain points in the field. The technical aim of the utility model is realized by the following technical scheme: Bilateral low pressure casting equipment, including the liquid reserve tank, liquid reserve tank middle part fixed mounting has the baffle, the baffle will liquid reserve tank internal portion is two partial pressure chamber, two equal fixed mounting has a stalk in the partial pressure chamber, be provided with the air inlet on the liquid reserve tank lateral wall, air inlet central point puts and is in on the baffle vertical direction, just the air inlet can be to two ventilate in the partial pressure chamber, rotate on the baffle and install the rotary drum, be equipped with the opening on the rotary drum lateral wall, be provided with the ring channel on the liquid reserve tank lateral wall air inlet exit, rotary drum one end rotate install in the ring channel, the rotary drum covers the air inlet export just around the air inlet rotates. Further, a motor is fixedly installed on the outer side of the liquid storage tank, and a shaft of the motor is connected with the center of the rotary drum, so that the rotary drum can be driven to rotate. Further stated, a heat insulation block is fixedly installed between the motor and the liquid storage tank. In summary, compared with the prior art, the utility model has the beneficial effects that the two partial pressure cavities can be separated or communicated by moving the rotary drum to different angles, one of the two partial pressure cavities can be ventilated and pressurized or pressurized simultaneously by changing the opening direction of the rotary drum, so that single-tube injection or multi-tube injection is realized, the air quantity entering the two partial pressure cavities at the same time can be regulated by regulating the opening angle of the rotary drum, and the injection rate in the two lift tubes can be controlled.
