Abstract
Description
Technical Field
[0001] This utility model relates to the field of control arm manufacturing technology, and in particular to a low-pressure casting arrangement structure for a control arm. Background Technology
[0002] A control arm consists of one control arm on each side. When casting the control arms using low-pressure casting, two molds are often arranged symmetrically on the left and right sides within the circular pouring range allowed by the production equipment, and each mold can produce one control arm. However, this conventional arrangement does not fully utilize the production equipment, resulting in low production efficiency. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a low-pressure casting arrangement structure that can make full use of the control arm of the production equipment.
[0004] The present invention adopts the following technical solution:
[0005] This utility model provides a low-pressure casting arrangement structure for a control arm, including three casting molds. Each casting mold has two symmetrically opened cavities for machining the control arm. The three casting molds are arranged circumferentially at equal intervals at the production equipment, and the gate of each casting mold is located in the circular pouring area of the production equipment.
[0006] Preferably, the casting mold has three gates, two of which are symmetrically located on the sides of the two cavities, while the third gate is located between the two cavities and connects the two cavities.
[0007] Preferably, the casting mold is axially symmetrical, and the outer edges of two adjacent casting molds are close to each other.
[0008] Preferably, the casting mold is made of AlSi7Mg cast aluminum alloy.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] Compared to conventional arrangements, the low-pressure casting arrangement of the control arm of this invention adds an extra mold. Although the three casting molds are not completely arranged within the circular pouring area of the production equipment, the gates on each casting mold are located within the circular pouring area of the production equipment. This ensures that each casting mold can be used for normal molten metal pouring through the gate, thereby making full use of the production equipment and improving the low-pressure casting production efficiency of the control arm.

[0022] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0025] See Figures 1 to 4 This embodiment provides a low-pressure casting arrangement structure for a control arm, including three casting molds 1. Each casting mold 1 has two cavities 101 symmetrically opened for machining the control arm 2. The three casting molds 1 are arranged circumferentially at equal intervals at the production equipment, and the gate 102 on each casting mold 1 is located in the circular pouring area 3 of the production equipment.
[0026] Compared to the conventional arrangement, the low-pressure casting arrangement of the control arm in this embodiment adds an extra mold. See [link / reference]. Figures 1 to 4 Although the three casting molds 1 are not completely arranged within the circular pouring area 3 of the production equipment, the gate 102 on each casting mold 1 is located within the circular pouring area 3 of the production equipment. This ensures that each casting mold 1 can be poured with molten metal through the gate 102, thereby making full use of the production equipment and improving the low-pressure casting production efficiency of the control arm 2.
[0027] Preferably, see Figure 3 and Figure 4 The casting mold 1 has three gates 102. Two gates 102 are symmetrically arranged on the sides of the two cavities 101, while the third gate 102 is located between the two cavities 101 and connects to both cavities 101. The two gates 102 located on the sides of the cavities 101 are used to deliver molten metal into their respective cavities 101, while the third gate 102 located between the two cavities 101 is used to additionally deliver molten metal into both cavities 101 to ensure that the molten metal can evenly fill the two cavities 101.
[0028] Preferably, see Figure 1 and Figure 2 The casting mold 1 has an axisymmetric design, with the outer edges of two adjacent casting molds 1 abutting each other. Thus, the three casting molds 1, by abutting each other, essentially form a stable triangular structure, which can effectively reduce vibration and deformation during use and improve the low-pressure casting quality and precision of the control arm 2.
[0029] Preferably, the casting mold 1 is made of AlSi7Mg cast aluminum alloy.
[0030] The low-pressure casting arrangement structure of the control arm of this utility model has been put into production and application. The casting mold is performing well, and the pass rate of the control arm castings has reached an extremely high level. Obviously, this arrangement structure is very suitable for the processing and production of control arms and similar products.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
