Embodiment Construction

[0014] The invention relates to a processing technology of a plastic oil tank of a hydraulic power unit, including an injection molding technology and a plastic welding technology.

[0015] Described injection molding process comprises the following steps:

[0016] a. Injection molding machine debugging: carefully check whether each system of the injection molding machine is normal before starting up, and conduct a trial run;

[0017] b. Mold installation: correctly install the mold on the injection molding machine;

[0018] c. Raw material pretreatment: when the raw material needs to be dried, it should be dried in the oven according to the regulations;

[0019] d. Process parameter adjustment: set the mold adjustment parameters until the mold runs normally, smoothly and safely;

[0020] e. Preheating the injection molding machine: set the temperature of each section of the barrel, and preheat the machine tool;

[0021] f. Pre-molding: When the material temperature and mol...

Abstract

The invention relates to a machining process of a plastic oil tank of a hydraulic power unit. The machining process of the plastic oil tank of the hydraulic power unit comprises an injection molding process and a welding process, wherein the plastic welding process comprises earlier-stage treatment and welding flows. A tank body of the oil tank is manufactured through the injection molding process; walls of the molded oil tank are uniform; in addition, through the design of non-adhesive layers on the surfaces of a heat plate and a welding mold, the heat plate is not bonded with an adhesive surface, so that the product welding cohesion degree is improved, the product beauty degree is increased, the impact resistance is enhanced, and the low-temperature toughness is improved. Moreover, the system design is reasonable; the cost is reduced; and the machining process is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to a processing technology of a plastic oil tank, in particular to a processing technology of a plastic oil tank of a hydraulic power unit. Background technique [0002] The hydraulic power unit is assembled from a motor, a valve body, a wheel pump and a fuel tank. When working, the motor drives the gear pump through the coupling shaft to generate pressure oil, and the pressure and direction of the oil circuit are controlled through the valve plate to achieve the required pressure and control. As an important part of the hydraulic power unit, the oil tank is used to store oil, emit hot air, escape air, separate water, precipitate impurities and install components. At present, the fuel tanks on the market are metal fuel tanks. This product has a stable structure and excellent stamping resistance, but the metal surface is easily corroded, the service life of the product is short, the cost of raw materials is expensive, and the proc...
