Abstract

The utility model discloses a cold-and-hot dual-temperature mould warmer, which belongs to the casting-plastic mould auxiliary equipment. A machine shell 3 is provided with a cold oil tank 8 and a hot oil tank 10, and the hot oil tank 10 is provided with a hot oil-inlet pipe 13 and a hot oil- circulating pipe 4. An oil pump 1, a heater 12 and a usually-closed electromagnetic valve 14 are arranged on the hot oil-inlet-pipe and are connected with a mould 1 through a main oil-inlet pipe 15. The cold oil tank 8 is provided with a cold oil-inlet pipe 5 and a cold oil-circulating pipe 7. The oil pump 11 and a condenser 6 are arranged on the cold oil-inlet pipe 5 and are connected with the main oil oil-inlet pipe 15 through the usually-closed electromagnetic valve 14. The mould 1 is connected with the a main oil-circulating pipe 2 which is connected with the hot oil-circulating pipe 4 and the cold oil-circulating pipe 7 through the usually-closed electromagnetic valve 14. The machine shell 3 is provided with a computer plate 9. The utility model is not only of the heating function, but also of the temperature-descension function. The utility model can shorten the casting plastic period, enhance the production efficiency and can be used together with the inversed-casting mould.

Description

The cold-hot dual-temperature die heater

Technical field: the utility model relates to the injection mo(u)lding auxiliary equipment, particularly a kind of cold-hot dual-temperature die heater.

Background technology: die heater of the prior art can only be heated, and does not possess the limit temperature function, has prolonged product and production cycle, and production efficiency is not high.

Summary of the invention: the purpose of this utility model is to provide a kind of cold-hot dual-temperature die heater, by this machine injection cycle is shortened, and reaches the purpose of enhancing productivity.

Formation of the present utility model: form by cold oil case, deep fat case, oil pump, heater, normally closed solenoid valve, cooler, casing, computer plate and oil pipe, cold oil case 8 and deep fat case 10 are installed in casing 3, hot oil inlet pipe 13 and hot oil return pipe 4 are installed in deep fat case 10, oil pump 11, heater 12 and normally closed solenoid valve 14 are housed on hot oil inlet pipe 13, are connected with mould 1 by total oil inlet pipe 15; Cold oil inlet pipe 5 and cold oil return pipe 7 are installed in cold oil case 8, oil pump 11 are installed on cold oil inlet pipe 5 are connected with total oil inlet pipe 15 with cooler 6 and by normally closed solenoid valve 14; Mould 1 is connected with total oil return pipe 2, and total oil return pipe 2 is connected with cold oil return pipe 7 with hot oil return pipe 4 respectively by normally closed solenoid valve 14, and computer plate 9 is housed on casing 3.

Compared with the prior art, the utility model is simple in structure, and it not only possesses heating function, and can also lower the temperature, and can shorten injection cycle, guarantees product quality, enhances productivity.

Description of drawings: accompanying drawing is the utility model structural representation.
