Embodiment 1

[0013] The forming method of the car water tank body of this example comprises the following steps:

[0014] 1) Heat the plastic to 210°C, stir for 20 minutes to obtain a high-temperature plastic melt, cool half of the high-temperature plastic melt to 170°C, and obtain a low-temperature plastic melt;

[0015] 2) Fix the mold. The mold is provided with an upper glue inlet and a lower glue inlet, and the mold is preheated to 55°C;

[0016] 3) Inject the high-temperature plastic melt obtained in step 1) into the upper glue inlet of the mold through a nozzle. The temperature of the nozzle is 190°C, and the injection pressure is 85Mpa. In the lower glue inlet of the mold, the temperature of the nozzle is 150°C, and the injection pressure is 65Mpa;

[0017] 4) When the mold is fully injected, pressurize, the pressure of the pressurized is 65Mpa, the time of the pressurized is 20 seconds, and then demolded and cooled to obtain the automobile radiator box.

Embodiment 2

[0019] The forming method of the car water tank body of this example comprises the following steps:

[0020] 1) Heat the plastic to 230°C, stir for 25 minutes to obtain a high-temperature plastic melt, cool half of the high-temperature plastic melt to 190°C, and obtain a low-temperature plastic melt;

[0021] 2) Fix the mold. The mold is provided with an upper glue inlet and a lower glue inlet, and the mold is preheated to 65°C;

[0022] 3) Inject the high-temperature plastic melt obtained in step 1) into the upper glue inlet of the mold through a nozzle. The temperature of the nozzle is 210°C, and the injection pressure is 95Mpa. In the lower glue inlet of the mold, the temperature of the nozzle is 170°C, and the injection pressure is 75Mpa;

[0023] 4) When the mold is fully injected, pressurize. The pressure of the pressurization is 75Mpa, and the time of the pressurization is 25 seconds, and then demoulding and cooling to obtain the automobile radiator box.

Abstract

The invention discloses a molding method of a radiator body of an automobile radiator and relates to the technical field of automobile manufacturing. The molding method comprises the following steps of heating plastic, so that a high-temperature plastic solution is obtained; lowering the temperature by a half, so that a low-temperature plastic solution is obtained; preheating a mold; injecting the high-temperature plastic solution into an upper plastic inlet of the mold through a nozzle, and injecting the low-temperature plastic solution into a lower plastic inlet of the mold through the nozzle; after full injection of the mold is completed, conducting pressure maintaining; and then, conducting demolding and cooling, so that the radiator body of the automobile radiator is obtained. By means of the molding method, the problem that existing radiator bodies of automobile radiators are high in production cost can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a method for forming an automobile water tank body. Background technique [0002] China has become the world's largest consumer of automobiles, and the annual output of automobiles is gradually increasing. With the increase of automobile production, the current automobile materials focus on environmental protection and lightweight. At present, most of the water tanks used in automobiles are made of plastic. Mainly, the existing automobile water tank usually increases the thickness of the tank body to ensure the service strength of the water tank, which has the problem of high production cost, and if the tank body is too thin, there is also the problem of insufficient service strength. Contents of the invention [0003] The invention provides a molding method of an automobile water tank body, which can solve the problem of high production cost of the existing au...
