Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 with Figure 5 As shown, a die-casting mold for an aluminum alloy front cover of an automobile silicone oil fan clutch includes a fixed mold 1, a movable mold 2, and a middle mold 3 located between the fixed mold 1 and the movable mold 2. The middle mold 3 is movably connected There is a core assembly 4, on which there are several concentrically arranged silicone oil feed surface forming rings 5, and an annular silicone oil feed surface molding is formed between every two adjacent silicone oil feed surface forming rings 5 Cavity 6.

[0029] In the prior art, the common practice is that the front teeth of the product, that is, the inner side of the silicone oil fan clutch front cover 100, adopt an overall circular block shape, and then use machining methods to process the required ring shape in the later stage...

Abstract

The invention belongs to the technical field of die-cast molding, and relates to a die-cast molding mould of an aluminum alloy front cover of an automobile silicone oil fan clutch. The die-cast molding mould comprises a fixed mold, a movable mold and a middle mold located between the fixed mold and the movable mold, wherein the middle mold is movably connected with a core component; the core component is provided with a plurality of silicone oil feeding surface molding rings arranged concentrically; and an annular silicone oil feeding surface molding cavity is formed between every two adjacent silicone oil feeding surface molding rings. The wall thicknesses of oil guide rings are reduced, few bubbles are generated in a casting process, the overall quality of a product is uniform, and a rejection rate is low.

Description

technical field [0001] The invention belongs to the technical field of die-casting molding, and relates to a molding die for metal products, in particular to a die-casting molding die for an aluminum alloy front cover of an automobile silicone oil fan clutch. Background technique [0002] The silicone oil fan clutch uses silicone oil as the medium, and uses the shearing force of silicone oil to transmit torque. The speed of the fan is designed under the condition of ensuring that the engine is not overheated under the worst operating conditions. Therefore, during normal driving of the vehicle, the speed of the fan should be controlled within an appropriate range, so as to reduce noise and improve engine economy. . For engine-driven fans, a fan clutch is usually used to control their speed. The inside of the clutch is sealed with a viscous fluid (silicone oil), which transmits torque by its shear viscous force. There is a bimetallic sheet in front of the fan, which is used...
