Portion connects elevating lever, and the lifter plate is set to crucible bottom, and side is bonded with the inner wall of crucible and can be along the inner wall of crucible
Vertical activity, described connecting rod one end connecting substrate, the other end connect lifter plate, and gooseneck channel side is provided with inlet.
As further improved technical solution, the lower surface of the substrate is equipped with wind turbine, and upper surface is equipped with motor, described
Wind turbine is connect with motor, the wind turbine face injection punch head.
The vertical height at the center of the vertical height >=sprue at the center of the inlet as a preferred technical solution,
Degree.
As further improved technical solution, the lifter plate is always positioned at the lower section of injection chamber.
The thickness of the lifter plate is 1-3cm as a preferred technical solution,.
As further improved technical solution, the injection punch head is inserted vertically into gooseneck channel.
The cross section of the connecting rod is circle, a diameter of 1-3cm as a preferred technical solution,.
The material of the connecting rod and lifter plate uses polypropylene plastics as a preferred technical solution,.
Beneficial effects of the present invention are：
(1) structure that the present invention is moved up and down using control lifter plate, realizes the lifting of the liquid level of molten metal, produces
Two notable advantages, first, the course of work of die casting machine is divided into feed liquor process and non-feed liquor process (casting process), non-
During feed liquor, metal bath surface is declined, so that injection chamber becomes smaller with the contact area of molten metal at this stage, to prolong
The service life of injection chamber has been grown, while having avoided the iron-holder for increasing molten metal；Second, molten metal lifter plate rise or under
It during drop, is forced to flow, precipitation is generated so as to avoid molten metal, to ensure that the quality of die casting.
(2) design feature based on the present invention, feed liquor are in intermittent, the running channel that can be so brought to avoid continous way feed liquor
The case where interior pressure instability, to avoid die casting from generating flaw.
(3) injection punch head upper end is equipped with wind turbine, can immediately be cooled down to injection punch head, extends making for injection punch head
Use the service life.
(4) the configuration of the present invention is simple, it is easy to operate, and can reequip to obtain by original hot chamber machine, have good
Application and commercial promise.
