Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments. For the convenience of description, the positions of "upper", "lower", "left" and "right" are described in the orientations shown in the drawings of the description, but the implementation of the present invention The approach is not limited to this description of a fixed orientation.

[0024] A kind of front suspension film-coated sand mold is made up of die, punch and runner, and described die fits with described punch, and both are superimposed to form mold integral body, and runner (such as Figure 8 shown) is placed in the runner cavity 17 of the die, such as Figure 2~4 As shown, the front of the die is depressed to form four chambers of different shapes, which are side middle chamber 1, center chamber 2, side lower chamber 3 and side upper chamber 4, wherein the side lower chamber 3 and the side upper chamber The cavities 4 are located side by side on one side of...

Abstract

The invention belongs to the field of core shooting machine tooling, and relates to a front suspension precoated sand mold which comprises a concave mold, a convex mold and a pouring gate, wherein theconcave mold is combined with the convex mold; the two are superposed to form an overall square mold; the pouring gate is placed in a pouring gate cavity; mounting holes and tooling holes are arranged at four corners of the convex mold and the convex mold; the mounting holes of the two are correspondingly arranged; the concave mold and the convex mold are further provided with ejector pin holes and heating channels, wherein the ejector pin holes are arranged in a manner of penetrating fronts and backs, while the heating channels are arranged to penetrate upper ends and lower ends; a sand shooting channel is formed in the concave mold and leads to the outside to form a sand shooting opening. The front suspension precoated sand mold can reduce dosage of precoated sand through combination ofthe concave mold and the convex mold, can also ensure a good molding structure, can reduce the weight of the concave mold by an underlaying cavity designed in the back of the concave mold, can effectively improve product molding precision and efficiency, and ensures high quality and low rejection rate of products.

Description

technical field [0001] The invention belongs to the field of tooling for core shooters, and relates to a sand-coated mold for a front suspension. Background technique [0002] The front suspension is the moving part of the car and one of the important components of the car, such as figure 1 As shown, the selection of its parameters and the arrangement of the guiding mechanism have an important impact on the ride comfort, stability, passability and fuel economy of the vehicle. In related technologies, sand casting is generally used to make the front suspension, while the foundry industry generally uses coated sand molds to make sand molds. The production process is roughly to inject the coated sand into the mold with a heating device through a core shooter. High-temperature heating makes the coated sand close to the surface of the mold solidified by heat, and then forms a sand mold. The mold used in the casting process of the prior art, after casting and cooling, the casting...
