The mold is heated to 140-150 ℃ by a high-temperature medium. The high temperature medium is generally an oil medium, which requires all pipes or flow passages to be resistant to high temperature and oil, which increases the cost, and also causes serious contamination of the machine and bottles once the medium leaks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a bottle blowing mold, includes left mould 2, right mould 3 and die block 5, all is equipped with the die cavity face on the medial surface of left mould 2, on the medial surface of right mould 3, on the medial surface of die block 5, its characterized in that: the outer side surface of the left die 2 and the outer side surface of the right die 3 are both provided with first heating holes 4, the outer side surface of the bottom die 5 is provided with second heating holes 7, the first heating holes 4 and the second heating holes 7 are blind holes, first electric heaters and second electric heaters are respectively arranged in the first heating holes 4 and the second heating holes 7, and the first electric heaters and the second electric heaters are both electrically connected with a power supply.

The electric heater described above is a structure that generates heat after being energized, and includes, for example: metal heating wire type elements, PTC type heating elements, electrothermal film type heating elements, and the like. The electric heater is used as a heat source to directly heat the left die, the right die and the bottom die, so that the heat transfer efficiency is high, the heat transfer rate is high, the time for preheating the die in a production cycle can be shortened, and the production efficiency is improved; in addition, after the oily heat transfer medium is omitted, a pipeline for transmitting the heat transfer medium is omitted, the cost of equipment can be reduced, and the risk of pollution caused by the oily medium is avoided.

Furthermore, the first electric heater and the second electric heater are resistance heating pipes. The heating pipe comprises a resistance heating pipe and a radiation electric heating pipe, and the resistance heating pipe has high heat transfer efficiency and is relatively energy-saving.

Further, the side walls of the first electric heater and the second electric heater abut against the inner side walls of the first heating hole 4 and the second heating hole 7, respectively. The wall material of the resistance heating pipe is metal, the material of the die is also metal, and the heat transfer efficiency between the mutually abutted metal materials is high.
