The two adjustable injection positions are realized by lifting the injection cylinder and the valve block as a whole and then adding a pad. A single injection position has limitations for different molds, and two injection positions also have limitations, and adjustment is not very convenient. Summary of the invention:

[0003] The purpose of the utility model is to solve the existing problems and provide a stepless adjustable mechanism for the injection position of casting molding equipment.

[0004] The technical solutions of the utility model are as follows:

[0005] A casting molding equipment injection position stepless adjustable mechanism comprises a frame and an injection oil cylinder, wherein the stepless adjustable mechanism is arranged on the frame, and the injection oil cylinder is installed on the side of the stepless adjustable mechanism in a liftable manner, and the stepless adjustable mechanism comprises a gantry frame plate fixed on the frame, a valve plate slidably installed in the gantry frame plate, and a servo lifting assembly arranged on the top of the gantry frame plate and driving the valve plate.

[0006] Preferably, the frame is provided with a die-casting mechanism opposite to the steplessly adjustable mechanism.

[0007] Preferably, the injection cylinder is horizontally installed on the side of the valve plate.

[0008] Preferably, limiting protrusions are formed on both sides of the valve plate, and the limiting protrusions fit the side surfaces of the gantry frame plate.

[0009] Preferably, the servo lifting assembly includes a servo motor, a reducer and a screw lifter. The screw lifter is relatively installed on the top surface of the gantry frame plate, and the lower end of the screw is fixedly connected to the valve plate. The servo motor and the reducer cooperate to drive the screw lifter.

[0010] The beneficial effects of the utility model are as follows: the injection oil cylinder is steplessly adjustable within the adjustment range, the screw lifter is driven by the servo motor, and the screw drives the valve plate to be accurately lifted and lowered, so that the injection position can be accurately and conveniently adjusted.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] like Figure 1-2 As shown, a casting molding equipment injection position stepless adjustable mechanism includes a frame 1 and an injection cylinder 2, wherein the stepless adjustable mechanism is arranged on the frame 1, and the injection cylinder 2 can be lifted and lowered on the side of the stepless adjustable mechanism, and the stepless adjustable mechanism includes a gantry frame plate 3 fixed on the frame 1, a valve plate 4 slidably installed in the gantry frame plate 3, and a servo lifting assembly arranged on the top of the gantry frame plate 3 and driving the valve plate 4.

[0017] Specifically, the frame 1 is provided with a die-casting mechanism 5 opposite to the steplessly adjustable mechanism.

[0018] Specifically, the injection cylinder 2 is horizontally installed on the side of the valve plate 4 .

[0019] Specifically, limiting protrusions 6 are formed on both sides of the valve plate 4, and the limiting protrusions 6 fit the sides of the gantry frame plate 3. The limiting protrusions 6 can limit the position of the valve plate 4, and at the same time, the weight of the injection cylinder 2 can be distributed to the gantry frame plate 3 to avoid damage to the screw elevator 9.

[0020] Specifically, the servo lifting assembly includes a servo motor 7, a reducer 8 and a screw lifter 9. The screw lifter 9 is relatively installed on the top surface of the gantry frame plate 3, and the lower end of the screw is fixedly connected to the valve plate 4. The servo motor 7 and the reducer 8 cooperate to drive the screw lifter 9.

[0021] During operation, the screw lifter 9 is driven by the servo motor 7 and the reducer 8, and the screw drives the valve plate 4 to rise and fall accurately, so that the injection cylinder 2 can accurately adjust the injection position of the die-casting molding mechanism 5.
