Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a hot runner detector for injection molds. Background Technology

[0002] Hot runner molds are molds that use heating devices to keep the molten plastic in the runner from solidifying. Hot runners maintain the plastic in the runner and gate in a molten state through heating. Because heating rods and heating coils are located near or in the center of the runner, the entire runner from the injection molding machine nozzle outlet to the gate is at a high temperature, keeping the plastic in the runner molten. After the machine is stopped, it is generally not necessary to open the runner to remove the solidified material; when restarting the machine, it is only necessary to heat the runner to the required temperature.

[0003] Traditional heating rods or heating coils can only be checked for correct connection and open circuits when installed on the injection molding machine. When an open circuit or short circuit is found, the mold must be removed from the injection molding machine, which seriously affects the production schedule.

[0004] For example, Chinese patent document CN204687293U describes a hot runner detector for injection molds, comprising a handle, a lamp holder, and a plug connected in sequence. The lamp holder contains a power supply and circuitry, and an LED is mounted on it. The LEDs are connected in parallel, with each parallel circuit containing a break in the circuit. The two ends of the break are connected to the plug. When the plug is inserted into the hot runner connector, the two ends of the break connect to a heating rod and a heating coil, forming a circuit, and the LED illuminates. When the heating rod or heating coil is broken, a circuit cannot be formed, and the corresponding LED does not illuminate. Short circuit and open circuit detection can be performed before the mold is installed on the injection molding machine, and the continuity of the heating rod and heating coil is determined by the brightness of the built-in LED.

[0005] However, if the detector itself malfunctions and the circuit breaks during use, the LED light of the detector will always be off, regardless of whether the mold is in an open or closed circuit state, and it will be impossible to detect the quality of the mold. Utility Model Content
