Problems solved by technology

This method has the following disadvantages: 1) The method of pressing in will cause the distance between the upper surface of the inner bushing and the upper surface of the disc body to be inconsistent, thereby affecting the quality of mass production; 2) The same distance between the inner bushing and the disc body The axiality will be inconsistent, which will affect the manufacturing accuracy; based on the above shortcomings, it will eventually cause the flow of the gasoline pump to be inconsistent, which will affect the work of the car

Abstract

The invention discloses a manufacturing process of an oil outlet tray of a gasoline pump and the oil outlet tray of the gasoline pump. The process comprises the following steps of: (1) opening a mould, wherein a mould-opening pressure is 15 to 45 N and a mould-opening speed is 10 to 28 m / s; (2) putting a lining into the mould; (3) assembling the mould, wherein a mould assembly pressure is 15 to 80 N and a mould assembly speed is 5 to 45 m / s; (4) injecting, wherein injecting time is 18 to 23 S; (5) maintaining pressure, wherein a maintaining pressure is 14 to 17 N and pressure-maintaining timeis 18 to 25 S; (6) after finishing pressure maintaining, carrying out the steps (1) and (7) at the same time; (7) ejecting a moulded product, wherein an ejection pressure is 0 to 3 N and an ejection speed is 11 to 12 m / s; and (8) rejecting, wherein a rejecting pressure is 0 to 5 N and a rejecting speed is 12 to 15 m / s. By the process, the accuracy of the oil outlet tray is improved, and manufacturing cost is low.

Description

technical field [0001] The invention relates to an oil outlet pan of a gasoline pump, in particular to a manufacturing process for an oil outlet pan of a gasoline pump. Background technique [0002] The function of the gasoline pump is to suck the gasoline out of the fuel tank and press it into the float chamber of the carburetor through the pipeline and the gasoline filter. It is thanks to the gasoline pump that the gasoline tank can be placed at the rear of the car away from the engine and below the engine. [0003] Such as figure 1 As shown, the gasoline pump includes a housing 100, a motor 200 is arranged inside the housing 100, a front end cover 300 is installed on one end of the housing 100, a rear end cover 400 is installed on the other end of the housing 100, and the front end cover 300 is provided with an oil inlet port 3001, the rear end cover 400 is provided with an oil outlet 4001, an oil outlet pan 500 is installed at one end of the front end cover 300 in t...
