specific Embodiment approach 1

[0021] Specific implementation mode 1: Combination figure 1 To illustrate this embodiment, the mechanism of this embodiment includes a local pressurized insert 1, a cylinder 2, a connecting sleeve 3, and a cylinder 4. The transmission rod of the cylinder 4 is connected to one end of the local pressurized insert 1 through the connecting sleeve 3. The other end of the pressure insert 1 is installed in the cylinder 2 and contacts the pouring end of the part 5 to be processed, and the cylinder 2 is butted with the part 5 to be processed.

specific Embodiment approach 2

[0022] Specific implementation manner two: combination figure 2 To illustrate this embodiment, the end face of the cylinder 2 in this embodiment that is in contact with the part 5 to be processed is provided with a through hole 5-1 with a trapezoidal cross section, and the bottom angle of the trapezoid is 74°. The advantage of this structure is to avoid the cylinder wall The rapid solidification of the surrounding aluminum liquid hinders the operation of the local pressure mechanism. The other implementation steps are the same as the first embodiment.

specific Embodiment approach 3

[0023] Specific implementation mode three: combination Figure 1-Figure 3 To illustrate this embodiment, the method of this embodiment includes the following steps:

[0024] Step 1. Design and molding of the mold: adopt double-runner pouring method, design the main runner gate size is 29×24mm, draft angle is 5°, and the auxiliary runner gate is opened at the top of the part 5 to be processed At the wall thickness, the size is 20×15mm, and the draft angle is 10°;

[0025] Step 2. Aluminum alloy smelting: Put the aluminum alloy in a crucible and heat it to melt; after the aluminum alloy is melted, the aluminum liquid is refined and slag removed, and the temperature is lowered to a near liquidus temperature of 600-640℃;

[0026] Step 3. Squeeze casting process: The mold temperature machine is connected to the extrusion die through the cylinder 4, and the extrusion die and the mold temperature machine are debugged respectively. The final mold temperature machine is adjusted to 220-270°C...

Abstract

The invention relates to a local pressurization mechanism and a method for producing automobile engine suspension shock insulators by the same. The method solves the problems that an existing method for producing suspension shock insulators of four-wheel-driven automobiles is complex in process and long in producing period, and produced products are poor in internal quality, low in internal and surface hardness and poor in mechanical property. The scheme of the local pressurization mechanism includes that a transmission rod of an oil cylinder is connected with one end of a local pressurization pin through a connection sleeve, the other end of the local pressurization pin is mounted in an ejector sleeve and contacts with a pouring tail end of a part to be processed, and the ejector sleeve is in butt joint with the part to be processed. The method for producing the automobile engine suspension shock insulators by the local pressurization mechanism includes the steps: designing and molding a mould; smelting aluminum alloy; squeeze casting; progressively solidifying the part by smoothly cooling the mould by the aid of the oil cylinder during squeeze casting; and after the part is completely solidified, taking out the molded shock insulator for natural cooling to obtain a finished product. The local pressurization mechanism and the method for producing the automobile engine suspension shock insulators by the same are utilized to produce the suspension shock insulators of the four-wheel-driven automobiles.

Description

Technical field [0001] The invention relates to a local pressurizing mechanism and a method for manufacturing an engine suspension spacer. Background technique [0002] At present, four-wheel drive vehicle engine suspension spacers are produced by aluminum alloy metal gravity casting, pressure casting, forging, and ferrous metal precision casting methods. However, the engine mount septum produced by aluminum alloy gravity casting and die casting methods has poor internal quality and low surface hardness, and poor mechanical properties; although forging can meet internal quality and performance requirements, the subsequent processing volume is large and the cost is high; black The metal precision grinding casting has high density and low specific strength, which cannot meet the requirements of automobile lightweight and energy saving and environmental protection, and the machining allowance is large, and the cost remains high. It cannot meet the requirements of the continuously de...
