Abstract
An injection molding system includes a mold with a mold cavity, an injection device, and a temperature control device. The injection device is capable of injecting a molten material into the mold cavity. The temperature control device includes a heating system and a cooling system. The heating system utilizes hot fluid to increase a temperature of the mold to a predetermined upper temperature when the injection device starting to inject the material. The cooling system utilizes cool fluid to decrease the temperature of the mold to a predetermined low temperature when the material is being solidified in the mold cavity.
Claims16
An injection molding system comprising:
- a mold having a fluid channel and an mold cavity configured to receive molten materials;
- and
- a temperature control device comprising a heating system and a cooling system, the heating system configured to insert hot fluid to the fluid channel to heat the mold, and the cooling system is configured to insert cold fluid to the fluid channel to cool the mold;
- wherein the heating system comprises a fluid storage barrel and a plurality of heating tubes connected to the fluid storage barrel, the plurality of heating tubes are connected to each other in series and configured to heat fluid that is flowing from the fluid storage barrel to the fluid channel.
An injection molding method, comprising:
- pumping fluid from a fluid storage barrel to a mold;
- heating the fluid by a plurality of heating tubes that are connected in series when the fluid is flowing to the mold;
- introducing hot fluid flowing from the plurality of heating tubes to heat up the mold to a predetermined upper temperature;
- injecting a molten material to the mold cavity;
- using cold fluid to cool down the mold to a predetermined lower temperature.
