Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like figure 1 , figure 2 As shown, the sprue frock for sand casting includes a sprue 3 , a gasket 5 and a fixed plate 1 . The fixed plate 1 is fixed on the sand box with bolts 2, and a rubber gasket is provided at the contact part between the sand box and the fixed plate to avoid damage to the sand mold due to excessive pressure. The middle of the fixed plate is a hollow inverted conical structure, and the middle is facing the pouring channel. The pouring port 3 is placed in the conical structure, and is blocked by the boss 4 to prevent slipping. By adopting the invention, the sprue and the core of the sprue channel are manufactured separately, and the production is easier. After the casting is completed and the broken sand and metal shavings are cleaned, the sprue can be removed for cleaning, which avoids the residual broken sand,...

Abstract

The invention discloses a sand mold casting sprue tooling, and relates to the technical field of metal casting. The sand mold casting sprue tooling comprises a sprue, a washer and a fixing disc, wherein the middle part of the fixing disc is in an inverted cone shape, and is fixedly arranged on a sand box by a bolt structure, the washer is arranged between the fixing disc and the sand box, and the sprue is arranged in the middle part of the fixing disc, and is connected with a runner passage. The tooling has the advantage that the cleaning and maintenance of sprue are more convenient.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to a casting tool for low-pressure castings with sand cores. technical background [0002] Casting is a common method of producing castings. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. Usually, the sprue and the sprue channel core are integrated when making casting sand molds, which is inconvenient for maintenance. And the mold must be cleaned of broken sand, metal chips, etc. after the casting is completed. After the casting is taken out, the mold is cleaned directly with compressed air. The residual sand, metal chips and other impurities in the cavity ...
