Abstract
The invention discloses a molding machine comprising a machine body, a work table, a rotary rocking arm, a shaking device, a sand press and a mold lifter. The work table is provided with a working plate and is horizontally arranged. The rotary rocking arm is provided with a pressing plate. The top of the machine body is provided with a rotary shaft, and the rotary rocking arm is fixedly arranged on the rotary shaft and can rotate along the rotation of the rotary shaft. The work table is arranged at one lateral end of the machine body, and the rotary rocking arm drives the pressing plate to be arranged just above the work table during the to-and-for rotation. The molding machine enables the pressing plate to horizontally rotate along the rotary rocking arm; when the molding machine adds sands into a sand tank or lifts the mold, the rotary rocking arm and the pressing plate rotate for the certain angle firstly to make the upper part of the sand tank without hampers, therefore, the pressing plate does not need to be arranged at a higher position; and when a jacking compaction operation is carried out, the pressing plate rotates above the work table and the sand tank.
Description
Technical field
The invention belongs to the sand molding technical field, be specifically related to a kind of moulding machine.
Background technology
The key link of sand casting is moulding, and the core of moulding machine is a sand densifying mechanism.Squeeze moulding machine is a kind of low speed sand densifying mechanism that history decades is arranged in being applied to produce, and its sand densifying mechanism is comparatively simple, but the lower and skewness of compacting gained sand mold compactability; The formed clamp plate compacting helps improving the model top and the uniformity of sand mold compactability all around; But generally speaking, squeeze mo(u)lding gained sand mold compactability is lower, and particularly the sand mold die joint degree of packing is on the low side, and the gained casting dimension accuracy is lower, and surface quality is poor.
Along with Foundry Production development and development of technology, jolt squeezing machine, high-pressure molding machine and corresponding sand densifying method thereof have appearred in succession.Air impact molding machine and sand densifying method thereof are the Modeling Technology that closely develops rapidly during the last ten years and be used widely.But the position of moulding machine center platen can only up-down adjustment in the market, and it is comparatively loaded down with trivial details to regulate operation, because need add operations such as sand, molding for sandbox reserves the operating space, so pressing plate need be arranged on the higher height, cause the height of traditional design machine higher, and, need thicker sheet material to make body because the roof pressure power of moulding machine when the roof pressure sandbox is bigger, so cause it highly higher, waste material and comparatively heavy.
Summary of the invention
The purpose of this invention is to provide a kind of moulding machine that can effectively reduce whole height, save material.
