Problems solved by technology

If there is no conversion method for runner shape change, but also to meet the casting conditions, the process design can only be completed by reducing the cavity; reducing the cavity means reducing production, thereby increasing production costs

Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The invention provides a method for calculating the shape change of the runner of the pouring system for casting, which uses the volume method to establish a relational expression and calculate the shape change of the runner. Since the pouring process of castings is a process of filling with liquid metal, it is a matter of controlling a certain flow rate within a certain period of time. The spoiler is used to control the flow, so that the slag in the front runner has e...

Abstract

The invention discloses a method for calculating the shape change of a cross gate of a casting system for casting, which relates to the field of casting and comprises the following steps: establishing a cross gate calculation model VH = Sigma Aur * LH based on a volumetric method; and when the shape of the cross gate of the pouring system is changed, determining the cross gate sectional area sigma Aru2 = sigma Aru1 * LH1 / LH2 after the shape of the cross gate is changed according to the cross gate calculation model. The calculation process is simple, fast and accurate.

Description

[0001] The present invention is a divisional application titled "A Calculation Method for the Shape Change of the Runner of a Casting System", wherein the application number of the parent application is 201711372711.1, and the filing date is 2017.12.19. technical field [0002] The invention relates to the technical field of casting, in particular to a calculation method for the shape change of a runner of a gating system for casting. Background technique [0003] Casting gating system is established based on the principle of hydraulics and gradually perfected. The channel that guides the liquid metal to flow into the cavity in the mold is called the gating system, and the gating system is composed of sprue cups, runners, baffles, and ingates. The function of the runner is mainly to slow down the flow of liquid metal and prevent slag from entering the cavity. Design of the runner: The data of the runner is obtained from the cross-sectional area relation of the ingate or loo...
