Abstract

The invention relates to the technical field of casting riser feeding, and discloses a pressurizing device for a riser, which includes a pouring body and a hydraulic cylinder. A top plate is arranged above the pouring body, and both sides of the lower surface of the top plate are fixed. Support rods are provided, the lower ends of the two support rods are fixedly connected to both sides of the upper surface of the corresponding casting body, the hydraulic cylinder is fixedly arranged on the lower surface of the top plate, and the upper surface of the casting body is fixedly arranged There is a lower mold, the end of the piston rod of the hydraulic cylinder is fixedly provided with an upper mold, the inside of the lower mold and the upper mold are both provided with a cavity, and the two ends of the upper surface of the upper mold are respectively provided with gates and risers In addition, both the gate and the riser are connected to the corresponding cavity, and both sides of the lower mold are provided with rotating rods through rolling bearings. The pressurizing device for the riser can conveniently pressurize the riser, effectively improving the process yield of the product.

Description

technical field [0001] The invention relates to the technical field of casting riser feeding, in particular to a pressurizing device for a riser. Background technique [0002] Gravity casting is the most commonly used casting method in the field of casting. At present, the static pressure of molten metal in the gate and riser is used to feed the product, and the feeding effect depends on the pouring of molten metal in the gate and riser. Due to the gravity (static pressure) generated by the high height, it is necessary to inject an excessive amount of molten metal, resulting in more gate and riser heads remaining after feeding in the gate and riser, which reduces the process yield and consumes more materials. It costs energy and the production cost is high. [0003] Wherein the patent No. CN110625069A discloses a pressurizing device for a riser. When in use, after the metal upper mold and the metal lower mold are closed, the riser sealing cylinder presses and seals the rise...
