Problems solved by technology

When the upper mold is ejected with castings, multiple power cylinders are used on the upper mold, and multiple power cylinders are required to be ejected at the same time. The movement synchronization is required to be very precise. If the mold cannot be ejected synchronously, the casting will be deformed; The mold is reversible, and its counterweight factor and long stroke cannot maintain concentricity, so the mold cannot be concentrically drawn when the upper mold belt casting is molded, and the casting is easily deformed by pulling the mold forcibly

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] see figure 1 As shown, the improved pouring casting production equipment includes a frame 10, a program control assembly, an oil cylinder assembly, an upper mold 30, a bottom mold 40, a side mold 50, and a lower release mechanism 60.

[0022] The upper end of the bottom mold 40 is provided with an upper limit plate 70 , and its lower end is provided with a lower limit plate 80 , and both the upper limit plate 70 and the lower limit plate 80 are fixed on the frame 10 . It also includes a retaining ring 90 , the unilateral gap between the retaining ring 90 and the bottom mold 40 is ≤0.6 mm, and is fixed on the frame 10 .

[0023] The program control assembly controls the movement of the cylinder assembly, the upper mold 30 is located above th...

Abstract

The invention discloses an improved pouring type casting production device which comprises a frame, a program control assembly, an oil cylinder assembly, an upper mould, a bottom mould and side moulds, wherein the program control assembly, the oil cylinder assembly, the upper mould, the bottom mould and the side moulds are arranged on the frame. The program control assembly controls the movement of the oil cylinder, the oil cylinder is connected with the bottom mould, the bottom mould is arranged under the upper mould, and the side moulds are arranged on the periphery of the upper mould. The improved pouring type casting production device further comprises a demoulding mechanism, the upper end of the demoulding mechanism is fixedly connected with the bottom mould, the lower end of the demoulding mechanism is connected with the oil cylinder assembly, and the oil cylinder assembly drives the demoulding mechanism to drive the bottom mould to move downwards. The improved pouring type casting production device only utilizes one power cylinder in the demoulding operation to enable a casting to be separated from the bottom mould smoothly, and meanwhile, solves the problem of decentraction caused by an overlong stroke in demoulding, so that the casting quality is improved.

Description

technical field [0001] The invention relates to a casting equipment, in particular to an improved pouring casting production equipment. Background technique [0002] At present, the pouring casting production process is as follows: mold closing, machine tilting at 90 degrees, pouring, machine rotation, casting forming, side mold parting, upper mold with casting from bottom mold, upper mold with casting Flip over and cast out. When the upper mold is ejected with castings, multiple power cylinders are used on the upper mold, and multiple power cylinders are required to be ejected at the same time. The movement synchronization is required to be very precise. If the mold cannot be ejected synchronously, the casting will be deformed; The mold is flipped, and its counterweight factor and long stroke cannot maintain concentricity. Therefore, the upper mold cannot be concentrically pulled out when the casting is pulled out, and the casting is easily pulled out of the mold and defor...
