Problems solved by technology
Its shortcoming is that the runners and inner runners of the casting casting system are made in the form of molds, and sand mold cavities are formed during molding, and the sand molds will be washed away for a long time after the molten iron flows through during casting.
Especially when casting large castings, the casting weight is

Example Embodiment
[0023] Such as Figure 1-12 Shown, it is a ceramic casting system, including sprue 3, runner and inner runner 6. The sprue 3 is set upright, the runner is horizontally arranged, and the bottom of the sprue 3 passes through the runner and the inner runner. The sprue 3, the runner and the inner runner 6 are made of ceramic materials. Several equal-diameter straight pipes 8, four-way pipes 9, elbow pipes 10, variable-diameter straight pipes 11, three-way pipes 7 and flat ports The pipe 12 is connected; the runner includes a connected runner inlet section 2 and a runner outlet section 5, and the sprue 3 and the runner inlet section 2 are sequentially connected by a plurality of equal-diameter straight pipes 8; The four-way pipe 9 has four openings, namely an upward opening, an opening on both sides and a downward opening. The upward opening of the four-way pipe 9 is connected to the lower end of the sprue 3, and the downward opening of the four-way pipe 9 is provided with Stopper ...

The invention discloses a ceramic casting system in the technical field of casting. A sprue, a cross gate and an ingate of the ceramic casting system are obtained by connection of several equal-diameter straight pipes, a fourway pipe, elbow pipes, variable-diameter straight pipes, t-branch pipes and flat mouth pipes made of a ceramic material. The sprue and the inlet section of the cross gate are obtained by connection of the equal-diameter straight pipes. The upward opening of the fourway pipe is connected to a lower end of the sprue. Two side openings of the fourway pipe are connected to one end of the inlet section of the cross gate. The elbow pipes are connected between the inlet section and an outlet section of the cross gate. The outlet section of the cross gate is obtained by connection of the equal-diameter straight pipes and the t-branch pipes. The equal-diameter straight pipes are connected to straight-through openings of the t-branch pipes. The ingate is obtained by connection of the variable-diameter straight pipes and the flat mouth pipes. Large-diameter ends of the variable-diameter straight pipes are connected to side openings of the t-branch pipes and each one of small-diameter ends of the variable-diameter straight pipes is connected to an end of the corresponding flat mouth pipe. Sides of the flat mouth pipes are provided with rectangular outlets communicated with a casting cavity. The ceramic casting system solves the problem of sand washing of the existing casting system in large-scale part casting, improves casting quality and is suitable for large-scale part casting.
Description
technical field [0001] The invention relates to the technical field of metal casting, in particular to a casting system. Background technique [0002] The casting system in the existing metal casting technology has a structure including a sprue cup, a sprue, a runner and an inner runner. The sprue cup is the inlet of the sprue. The sprue is set upright, and its bottom is connected with the horizontal sprue. The outlet of the sprue is connected with the inner sprue. The sprue is used to introduce liquid metal from the sprue cup. Runner and inner runner; at the same time, provide enough pressure head, so that the molten metal can overcome the resistance along the process and fill the mold within a specified time. The inrunner is the last channel for the liquid metal to enter the mold cavity. Its function is to control the speed and direction of the molten metal filling the mold, adjust the temperature of each part of the mold and the solidification sequence of the casting, an...
