Description

Technical Field

[0001] The present invention mainly relates to the technical field of injection molds, in particular to an injection mold and an injection mold recording system thereof. Background Art

[0002] Obtaining the production time of injection molding machine parts typically requires purchasing a license for the corresponding injection molding machine and accessing the machine's internal data. These licenses are typically paid annually, and data loss can occur when the network or system is unstable. Therefore, matching injection mold product and production information is a challenge in mold production.

[0003] Existing methods and devices for monitoring injection mold production include: real-time acquisition of actual temperature values ​​at multiple detection points on the mold; comparison of the actual temperature values ​​with a set target temperature range to determine whether the injection molding process is operating normally; shutting down the mold if the injection molding process is abnormal, otherwise maintaining normal operation; and displaying the actual temperature value. This monitoring method not only monitors the working conditions of the mold, but also promptly stops the mold if the injection molding process is operating abnormally, facilitating adjustments and handling by staff. This effectively reduces the rejection rate of injection molded products, improves product quality and consistency, and ensures the stability of injection molding production.

[0004] The methods and devices in the prior art can not only monitor the working condition of the mold, but also stop the operation of the mold in time when the injection molding process operates abnormally.

[0065] The working principle of the present invention is:

[0066] When producing an injection mold, the mold must first be clamped onto the injection molding machine. The injection molding machine drives the mold to move to achieve injection molding. The injection mold production of plastic parts includes the following steps: mold closing, injection molding, mold opening, part ejection, part removal, and part ejector rod reset. The above steps constitute the injection molding process of one plastic part.
