Embodiment 1

[0023] Example 1: put the oil pipe into the oven to preheat, put the No. 1 oil pipe 1 on the upper layer of the oven, and put the No. 2 oil pipe 2 on the lower layer. The time is 5 minutes; after the production is completed, the operator clamps the sprue of the oil pan with pliers, drags the bottom of the oil pan 8 with a wooden hammer, and puts the product on the knocking platform, and the operator holds the sprue of the product with the pliers in his left hand , take a wooden hammer in the right hand to remove the slag bag of the product, and then use the wooden hammer to break off the runners on both sides. The wooden hammer hits the middle of the material handle to break the material handle. pieces, put six layers, 36 pieces per board.

Embodiment 2

[0024] Example 2: put the oil pipe into the oven to preheat, put No. 1 oil pipe 1 on the upper layer of the oven, and No. 2 oil pipe 2 on the lower layer. The time is 5 minutes; after the production is completed, the operator clamps the sprue of the oil pan with pliers, drags the bottom of the oil pan 8 with a wooden hammer, and puts the product on the knocking platform, and the operator holds the sprue of the product with the pliers in his left hand , take a wooden hammer in the right hand to remove the slag bag of the product, and then use the wooden hammer to break off the runners on both sides. The wooden hammer hits the middle of the material handle to break the material handle. pieces, put six layers, 36 pieces per board.

Embodiment 3

[0025] Example 3: put the oil pipe into the oven to preheat, put No. 1 oil pipe 1 in the upper layer of the oven, and put No. 2 oil pipe 2 in the lower layer. The time is 5 minutes; after the production is completed, the operator clamps the sprue of the oil pan with pliers, drags the bottom of the oil pan 8 with a wooden hammer, puts the product on the knocking nozzle table, and the operator holds the sprue of the product with the pliers in his left hand , take a wooden hammer in the right hand to remove the slag bag of the product, and then use the wooden hammer to break off the runners on both sides. The wooden hammer hits the middle of the material handle to break the material handle. pieces, put six layers, 36 pieces per board.

[0026] To sum up, the present invention has the following advantages: the oil pipe is positioned accurately, the positioning hole of the oil pipe will not leak aluminum, and the oil pipe will not be flattened and deformed due to uneven force.

Abstract

The invention discloses a die-casting method of a thin-wall oil pipe embedding part oil pan. The method comprises the steps of preheating oil pipes through an oven; moving a wood board at the bottom of a machine stand to reach the middle of a die to prepare for mounting the oil pipe; moving out the heated oil pipes from the oven; keeping the surfaces of the oil pipes free of oil stain; aligning the middle of the oil pipes to two end heads; mounting the #1 oil pipe above and mounting the #2 oil pipe below, wherein the #1 oil pipe and the #2 oil pipe are respectively mounted on corresponding fixing points of the oil pan; examining whether the #1 oil pipe and the #2 oil pipe are clung to a U-shaped clamping slot; connecting the #1 oil pipe and the #2 oil pipe through a plurality of aluminum embedding part blocks which are fixed on the U-shaped clamping slot in the die before closing the die and pouring of a die-casting machine; moving out the oil pan after production; examining whether the oil pipes expose, oil pipe feeders and each pin hole are damaged by buckling, and an interlayer and each corner are burnt and adhered with aluminum. The method has the advantages that the oil pipes can be accurately positioned, aluminum cannot overflow from oil pipe positioning holes, and the oil pipes cannot be flattened and deformed due to non-uniform stressing.

Description

technical field [0001] The invention relates to a die-casting method for a thin-wall oil pipe insert oil pan. Background technique [0002] The oil pan is located at the lower part of the engine and can be disassembled, and seals the crankcase as an oil sump shell. The oil pan is mostly stamped from thin steel plates, and the ones with more complex shapes are usually cast iron or aluminum alloy. It is equipped with an oil stabilizing baffle inside to avoid the shock and splash of the oil surface caused by the bumping of the diesel engine, which is beneficial to the precipitation of lubricating oil impurities. There is an oil dipstick on the side to check the oil level. In addition, an oil drain plug is installed at the lowest point of the bottom of the oil pan. [0003] Most of the cars seen on the market are wet oil pans. The reason why they are named wet oil pans is that the crankshaft crank and connecting rod head of the engine will be immersed in the lubricating oil of...
