Problems solved by technology

[0004] At this stage, the technology of shooting glass cavity with camera and ultrasonic pulse reflection method are generally used to detect the state of the melt during the injection molding process. However, in the technology of shooting glass cavity with camera, the melt needs to pass through the glass cavity instead of the traditional one. The metal mold cavity reduces the strength of the mold cavity, which seriously affects the application of this technology; in the ultrasonic pulse reflection method, the installation position of the sensor is limited, and the melt state information provided is very limited and discrete
In addition, the two important steps of signal perception and signal filtering and amplification are carried out in different individuals, which not only increases the complexity of signal processing calculations, but also increases various external factors that affect signal accuracy, sensitivity, and stability.

Abstract

The invention discloses an integrated sensor in an injection molding die, and the injection molding die. The integrated sensor in the injection molding die comprises: a sensor main body (1) penetrating through a movable die core and forming two electrodes of a detection capacitor together with a fixed die core, and a sensing signal filtering and amplifying box (2) used for filtering and amplifyinga capacitance signal acquired by the sensor main body (1). The integrated sensor can obtain the state of a melt in a die cavity according to the change of the capacitance signal of the detection capacitor in different stages in the whole injection molding process, the detected melt state information is continuous and abundant, and the sensor main body and the sensing signal filtering and amplifying box are integrated to make the capacitance signal directly input to the sensing signal filtering and amplifying box in a zero distance manner from the sensor main body, so the precision, the sensitivity and the stability of the sensing signal of the integrated sensor are improved, and the service life of the integrated sensor is prolonged.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an integral sensor in an injection mold and an injection mold. Background technique [0002] With the sublimation of fierce competition in the product market, advocating high efficiency, energy saving, environmental protection, and low cost has become the magic weapon and foundation for enterprises to win in the competition. One of the key links is the efficiency and quality monitoring of the production process of injection molding products. High intelligence of control and control, low cost expenditure, effective resource utilization and other aspects put forward higher, more competitive, smarter and more automated requirements. [0003] During the entire injection molding process, the state of the melt in the cavity changes greatly, and these changes have a decisive impact on the quality of the product. Therefore, the detection of the melt state, especially the detecti...
