Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] A method for optimizing the cross-sectional shape and size of the runner of the gating system and a casting method of the present invention calculate the cross-sectional shape and size of the runner by using a relational expression composed of a width / height ratio of 0.618 (the golden section number).

[0044] It mainly includes the following steps:

[0045] Step 1, such as figure 1 As shown, the area of ​​the runner section of the casting gating system is shown in formula (1),

[0046] ∑Aru=h×w (1)

[0047] Step 2, the present invention adopts the golden section number that width / height ratio is 0.618 to calculate, as formula (2)

[0048] As shown, w=h×0.618 (2)

[0049] In the formula, ∑Aru represents the cross-sectional area of ​​the runner, h represents the height of the runner section, and w represents the theoretical width of the runner secti...

Abstract

The invention relates to an optimization method for the shape and size of the cross section of a cross gate of a pouring system and a casting method, relates to the field of casting, and solves the problems that an existing calculation method is inaccurate in calculation result, needs table look-up in the calculation process, is complex in operation and wastes time and labor. According to the method, the golden section number of 0.618 is adopted to calculate the shape and size of the cross section of the cross gate; according to the area formula sigma Ar = h * w of the cross section of a pouring system for casting, the ratio of the theoretical width w of the cross section of the cross section to the height h of the cross section of the cross section is set to be the golden section number 0.618, and a calculation formula of the upper edge length c passing through the cross section of the cross section is obtained through calculation; a is approximately equal to 0.636 h, and b is approximately equal to 0.601 h according to a calculation formula of the lower edge length a of the cross section of the cross gate and a calculation formula of the actual width b of the cross section of the cross gate. According to the method, table look-up is not needed in the calculation process, calculation is simple and accurate, and waste of metal materials is avoided.

Description

[0001] This application is a divisional application of a patent application titled "A Calculation Method for the Cross-Section Shape and Dimensions of the Runner of a Casting System". The filing date of the original application is December 19, 2017, and the application number is 201711372515.4. technical field [0002] The invention relates to the field of casting technology, in particular to a method for optimizing the cross-sectional shape and size of a runner of a gating system and a casting method. Background technique [0003] The gating system is composed of sprue cup, sprue, runner (runner) and ingate, which is a channel opened in the mold for introducing liquid metal into the cavity of the mold. The function of the gating system is to control the speed at which the molten metal fills the mold and the time required to fill the mold, so that the molten metal enters the mold smoothly, avoiding turbulence and erosion of the mold; preventing slag and other inclusions from ...
