Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of injection molding machine, in particular to adjustable installation position's electric heating ring of independent temperature control structure of nozzle applied to injection molding machine. BACKGROUND

[0002] Injection molding machine is a kind of thermoplastic or thermosetting plastics using plastic molding die is made into various shapes of plastic products plastic forming equipment. The working principle of injection molding machine is similar to that of syringe for injection, it is mainly a kind of by screw or plunger's thrust, the plastic of molten state, i.e. viscous flow state is injected into closed mold cavity, and the product is obtained after solidification and setting. The injection molding is a cyclic process, each cycle mainly includes: quantitative feeding-melting plasticizing-pressurizing injection-mold cooling-opening mold and taking out; After the operator takes out the plastic part, the mold is closed again for the next cycle.

[0003] The injection molding machine described above when conveying, molten plastic will pass through the extrusion pipe of injection molding machine and then enter the mold;Therefore, in the process of conveying molten plastic, it needs to be heated to avoid plastic solidification. Therefore, an electric heating ring device is usually fixed on the extrusion pipe of the injection molding machine to realize the function of on-demand heating.

[0004] Based on this, Chinese patent CN218615307U discloses a kind of ceramic electric heating ring threading ceramic components for injection molding machine, it includes injection molding machine extrusion pipe, the outer wall of the injection molding machine extrusion pipe is evenly provided with metal shell, and the inner wall of metal shell is pasted with heat preservation insulation cotton, the inner wall of the heat preservation insulation cotton is evenly installed with ceramic threading strip assembly, the middle position of the both sides of metal shell is installed with fixing piece by bolt.The technical scheme disclosed in the patent document is locked by rotating fixing bolt and pulling elastic fixing belt for limiting, to avoid the loosening of fixing bolt and the rotation of fixing bolt, and the rubber pads are pressed against each other to form a closed seal to prevent heat leakage. Then pull the rubber rings of adjacent ceramic electric heating rings to adhere to each other, thereby closing the gap between adjacent ceramic electric heating rings. The rubber pads and heat preservation insulation cotton cooperate to prevent temperature leakage during operation, so that the temperature during operation can be completely transferred to the injection molding machine extrusion pipe, thereby solving the problem of heat leakage from the gap.

[0005] However, the disclosed electric heating ring device still has the technical problem of inconvenient installation. Specifically, when the existing injection molding machine is modified to have independent temperature control of the nozzle, the transition nozzle electric heating ring will have an additional hole to install the thermocouple, and the installation position of the electric heating ring will be fixed and cannot be adjusted. Therefore, during installation, the wiring may interfere with the internal hexagonal screw of the machine cylinder before installation. In order to solve such problems, it is usually necessary to re-drill holes on the electric heating ring to change the installation position of the electric heating ring. Each time the electric heating ring is installed on different models of injection molding machines, re-drilling is required for installation, which is relatively inconvenient in operation.
