Abstract
The invention discloses a kind of forming method of radiator casing, it is related to field of automobile, comprises the following steps：Plastic heating is obtained into high temperature plastics solution, half cools to obtain cold plastics solution；Mould is preheated；In the upper glue-feeder that high temperature plastics solution is passed through into nozzle injection to mould, in the lower glue-feeder that cold plastics solution is passed through into nozzle injection to mould, pressurize is carried out after the full mould of injection, then the demoulding, which cools down, produces radiator casing, and it can solve the problems, such as that existing radiator casing production cost is high.
Description
Technical field
The present invention relates to field of automobile, especially a kind of forming method of radiator casing.
Background technology
China has become the big area of consumption of the first in the world of automobile, and annual auto output is being stepped up, with automobile
The increase of yield, and present automotive material stresses and environmental protection and lightweight, most of water tank used in automobile is with modeling at present
Based on material, existing radiator generally increases the thickness of casing to ensure the use intensity of water tank, and it is big to there is production cost
, if casing is too thin and the problem of use intensity deficiency be present in problem.
The content of the invention
The present invention provides a kind of forming method of radiator casing, and it can solve existing radiator casing and be produced into
The problem of this is high.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention comprises the following steps：
1）By plastic heating to 210~230 DEG C, stirring obtains high temperature plastics solution in 20~25 minutes, and the high temperature plastics is molten
Body half is cooled to 170~190 DEG C, obtains cold plastics solution；
2）Mould is fixed, the mould is provided with upper glue-feeder and lower glue-feeder, the mould is preheated into 55~65 DEG C；
3) by step 1）In upper glue-feeder of the gained high temperature plastics solution by nozzle injection to the mould, the nozzle temperature
For 190~210 DEG C, the injection pressure is 85~95Mpa, by step 1）Gained cold plastics solution passes through nozzle injection to institute
In the lower glue-feeder for stating mould, the nozzle temperature is 150~170 DEG C, and the injection pressure is 65~75Mpa；
4）Pressurize is carried out after the full mould of injection, the pressure of the pressurize is 65~75Mpa, and the time of the pressurize is 20
~25 seconds, then the demoulding, which cools down, produced radiator casing.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
High temperature plastics solution is carried out using the higher nozzle of temperature by high pressure injection from the upper glue-feeder of mould, high temperature plastics is molten
Liquid flowability is preferable, quickly dispenses mould upstream completely, the casing part is relatively thin；Low temperature is moulded using temperature relatively low nozzle
Expect that solution carries out low pressure injection from the lower glue-feeder of mould, cold plastics melt flow is poor, at a slow speed by mold bottom
Dispensing is full, and the casing part is thicker；After mould is filled with, the casing that a kind of top is thin, bottom is thick is obtained, water tank bottom is to hold
The maximum place of stress is carried, and water tank upper stress is small, thin base thickness on the radiator casing being molded by the present invention, has upper
The characteristics of portion is in light weight, and bottom strength is high, reduce the material needed for the shaping of casing upper part.
Embodiment
With reference to instantiation, the invention will be further described：
