Problems solved by technology

[0009] However, the injection molding machine described in Patent Document 1 intends to suppress the variation in the amount of resin in each shot amount by estimating the amount of resin in the injection cylinder based on only monitoring the metering time, and the injection molding machine described in Patent Document 2 It is intended to suppress the deviation of the resin state in each shot amount by estimating the state of the resin in the injection cylinder based on the energization rate of each of the average unit time monitored by the plurality of band heaters. The state of the resin in the injection cylinder affected by these factors is insufficient, and the molding quality affected by the state of the resin cannot be judged with high accuracy.

Embodiment 1

[0040] figure 1 It is a diagram showing a configuration example of the plasticizing state monitoring device 100 mounted on the injection molding machine according to the embodiment of the present invention. In this embodiment, the plasticizing state monitoring device 100 monitors the energy consumed when plasticizing the resin. change, and display the information related to the consumed energy on the display device as information related to the plasticizing state.

[0041] Specifically, the control device 1 of the plasticizing state monitoring device 100 receives the measurement result from the power measurement device 2 , and outputs various information based on the measurement result to the display device 4 .

[0042] figure 2 It is a schematic diagram of an injection / plasticizing device 200 in an injection molding machine according to an embodiment of the present invention. The injection / plasticizing device 200 mainly includes: a cylinder heater 6 (for example, divided in...

Embodiment 2

[0066] Next, refer to Figure 4 A molding quality judging device 100A mounted on an injection molding machine according to an embodiment of the present invention will be described.

[0067] Figure 4 It is a diagram showing a configuration example of a molding quality judging device 100A mounted on an injection molding machine according to an embodiment of the present invention. In this embodiment, the molding quality judging device 100A monitors the energy consumed when plasticizing the resin, The value of the monitored energy consumption determines the quality of the molded product.

[0068] In addition, the molding quality judging device 100A is different from the plasticizing state monitoring device 100 in that the control device 1A includes a molding quality judging unit 11 and a consumption energy fluctuation suppressing unit 12, and refers to the information stored in the storage device 3 to The sound output device 5 , the cylinder heater 6 , and the metering motor 7 ...

Abstract

An injection molding machine which monitors a state of resin in an injection cylinder (20) includes an energy consumption detecting part (100,2) which detects an amount of energy consumed in plasticizing resin. The injection molding machine also includes a molding quality judging part (100A,11) which judges molding quality based on the consumed energy detected by the energy consumption detecting part (2) and an energy consumption stabilizing part (12) which stabilizes the consumed energy detected by the energy consumption detecting part.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2010-241390 filed on October 27, 2010. All the contents of the application are incorporated in this specification by reference. technical field [0002] The present invention relates to an injection molding machine which monitors the plasticized state of resin. Background technique [0003] In the past, it is known to detect the metering time (referring to the time until the metering screw rotates and the molding material is metered and accumulated in the nozzle portion at the front end of the injection cylinder after the injection of the molding material from the nozzle to the mold, and the metering screw gradually retreats and the metering is completed), and An injection molding machine that controls the rotation speed of a feed screw based on the difference between this metering time and a predetermined reference metering time (for example, refer to Patent Document 1). [0004] Accordingly, ...
