Abstract

The utility model discloses a novel molten metal drainage groove, which belongs to a production facility in the casting industry. The groove body of the novel molten metal drainage groove is a graphite groove with a U-shaped cross section; the depth of a groove of a head part is greater than that of a groove of a tail part; the width of the groove of the head part is greater than that of the groove of the tail part; the head part is in arc smooth transition with the tail part; the tail part is provide with a drainage plate which is a flat plate forming an inclined acute angle between 3 degrees and 5 degrees with the outer surface of the groove bottom of the U-shaped groove of the tail part; and the width of the drainage plate is the same as that of the groove bottom of the U-shaped groove of the tail part. The novel molten metal drainage groove has an open structure, so that the drainage groove is convenient to operate, check and clear; due to the formation of a drainage curve at the bottom, falling of molten metal in a specified falling range can be better ensured; and the molten metal enters the cavity of a mold within 2 to 4 seconds, so that stable and quick mold filling is achieved, and the performance and quality of a product are ensured.

Description

Novel metal liquid drainage groove

Technical field

The utility model belongs to the production facility of casting industry, is mainly used in the running gate system of thermodyn process centrifugal casting, and its effect is that molten metal is drained in the casting pattern from quantitative bag, is specifically related to a kind of novel metal liquid drainage groove.

Background technology

In the centrifugal casting production process, cooling velocity was very fast after molten metal entered the metal die inner chamber of at a high speed rotation, produces very big centrifugal force and guarantee moulding in rotation at a high speed.Therefore need molten metal to be drained in the dies cavity fast and stably.The drainage system that uses at present is Fig. 1, Fig. 2, cattle horn shape drainage system shown in Figure 3, it is by steel welding or cast iron moulding, its structure is to have the little core structure of import large outlet, after molten metal is injected into, can cause that molten metal splashes seethes, do not possess enough good steady drainage, it is defective to cause watering the product that outpours, and product quality descends.

Summary of the invention

In order to improve the cast product quality, the utility model provides fast, a kind of novel metal liquid drainage groove of steady drainage.

Cell body of the present utility model is the graphite groove that cross section takes the shape of the letter U, it is dark that the degree of depth of the groove of the depth ratio afterbody of the groove of its head is wanted, the width of the groove of head is wideer than the width of the groove of afterbody, head seamlessly transits to the afterbody camber, afterbody is provided with drainage plate, drainage plate is for becoming the flat board of 3 ~ 5 degree acute rake angles with afterbody U-shaped groove bottom land outer surface, drainage plate and afterbody U-shaped groove bottom land are with wide.

The utility model is the opened type structure, is convenient to operation and checks cleaning; The drainage trough of bottom is an arc curve, can guarantee better that molten metal drops on the drop point scope of defined, and molten metal entered dies cavity in 2 ~ 4 seconds, obtain filling steadily, fast type, to guarantee the properties of product quality.

The specific embodiment:

Embodiment: Fig. 4, Fig. 5, shown in Figure 6, present embodiment is the graphite groove that cross section takes the shape of the letter U, it is dark that the degree of depth of the groove of the depth ratio afterbody 2 of the groove of its head 1 is wanted, the width of the groove of head 1 is wideer than the width of the groove of afterbody 2, head 1 seamlessly transits to afterbody 2 cambers, afterbody 2 is provided with drainage plate 3, and drainage plate 3 is for becoming the flat board of 5 degree acute rake angles with afterbody U-shaped groove bottom land outer surface, and drainage plate 3 and afterbody U-shaped groove bottom land are with wide.

Claims

1. novel metal liquid drainage groove, it is characterized in that cell body is the graphite groove that cross section takes the shape of the letter U, it is dark that the degree of depth of the groove of the depth ratio afterbody of the groove of its head is wanted, the width of the groove of head is wideer than the width of the groove of afterbody, head seamlessly transits to the afterbody camber, afterbody is provided with drainage plate, and drainage plate is for becoming the flat board of 3 ~ 5 degree acute rake angles with afterbody U-shaped groove bottom land outer surface, and drainage plate and afterbody U-shaped groove bottom land are with wide.
