Embodiment Construction
[0011] The present invention will be described in further detail below by means of specific embodiments:
[0012] The reference signs in the drawings of the specification include: cover body 1 , resistance ring 2 , retaining ring 3 , wire chamber 4 , and wire 5 .
[0013] The embodiment is basically as attached figure 1 , figure 2 Shown: a mold cover for centrifugal casting, including a circular cover body 1, the center of the upper end of the cover body 1 protrudes upwards in a conical shape, and a main resistance ring 2 is fixed in the middle of the bottom of the cover body 1. The outer side of the main resistance ring 2 is provided with six ring-shaped and evenly distributed secondary resistance rings 2, and the outer sides of the main resistance ring 2 and the secondary resistance ring 2 are provided with a retaining ring 3 integrally formed with the cover body 1. The resistor coil 2 is formed by helically winding filamentary Cr20Ni80. The inside of the cover 1 is prov...

The invention discloses a mold cover for centrifugal casting in the field of centrifugal casting of molds. The mold cover comprises a round cover body, wherein the upper end of the cover body protrudes centrally and upwards to form a conical bulge; a primary resistance coil is fixed in the center of the bottom of the cover body; a plurality of secondary resistance coils which are distributed annularly and uniformly are arranged on the periphery of the primary resistance coil; retainer rings which are formed into a whole with the cover body are all arranged on outer sides of the primary resistance coil and the secondary resistance coils; a wire cavity is formed inside the cover body; the wire cavity is a conical cavity with a larger lower portion and a small upper portion; wire holes which are in one-to-one correspondence to the resistance coils are formed in the bottom of the wire cavity; both the primary resistance coil and the secondary resistance coils are connected with electric wires; and the electric wire penetrate through the wire holes and the wire cavity. According to the scheme, a plurality of mold cavities can be heated simultaneously, so that the mold cavities work simultaneously, a plurality of workpieces can be shaped once, and the production efficiency of centrifugal casting molding is improved.
Description
technical field [0001] The invention relates to the field of centrifugal casting molds, in particular to a mold cover for centrifugal casting. Background technique [0002] Centrifugal casting machine is a casting equipment that pours liquid metal into a rotating mold, fills the mold under the action of centrifugal force and solidifies it into a casting. The characteristics of centrifugal casting are that the molten metal is filled and solidified under the action of centrifugal force, the metal feeding effect is good, the casting structure is compact, and the mechanical properties are good; casting hollow castings does not require a pouring riser, and the metal utilization rate can be greatly improved. However, in the existing centrifugal casting equipment, only a single part can be cast at a time, and for rod and bar parts, the centrifugal casting equipment has a large volume and low production efficiency, which is not conducive to mass production. Therefore, it is necessar...
