Problems solved by technology

In the prior art, a common method used to control the stop of the moving mold after opening the mold is to use the maximum friction force that the machine itself can achieve to control the moving mold to stop in a non-linear deceleration manner. However, the above deceleration and emergency stop methods are often The excessive force on the entire machine will cause the machine to vibrate obviously, and even cause breakage and damage to the machine components, which will greatly shorten the life of the machine and affect the quality of injection molding
Although the above problems can be solved by slowly dragging the mold, this method will lead to too long mold opening time and reduce the injection molding efficiency of the injection molding machine

Embodiment Construction

[0020] Please refer to figure 1 , which is a partial schematic diagram of the injection molding machine 10 proposed according to an embodiment of the present invention, as figure 1 As shown, the injection molding machine 10 can be an automatic machine commonly used for the injection molding process (the relevant descriptions of the automatic mechanism action of the machine and the principle of the injection molding process are commonly found in the prior art. To simplify the description, here This will not be described in detail) and includes a base 12 , a static mold 14 , a movable mold 16 , and a control module 18 . The static mold 14 is arranged on the base 12, and the movable mold 16 is movably arranged on the base 12 to be operatively close to the static mold 14 to carry out the mold closing process or away from the static mold 14 to carry out the mold opening process, so as to be compatible with the static mold 14 jointly execute the injection molding process.

Abstract

The invention discloses a mold opening control method which is suitable for an injection molding machine table, the injection molding machine table is provided with a movable mold and a static mold, and the movable mold is operably far away from or close to the static mold so as to execute an injection molding process. The mold opening control method comprises the steps that a setting unit sets the brake initial speed, the brake deceleration and the preset mold opening distance of the movable mold, a driving unit controls the movable mold to be opened according to the brake initial speed and the brake deceleration and decelerates to stop in an equal deceleration mode, and a sensing unit detects the actual mold opening distance of the movable mold; and an arithmetic unit judges whether theinitial brake speed and the brake deceleration of the movable mold are changed through the setting unit or not according to the preset mold opening distance and the actual mold opening distance, and controls the driving unit to adjust the mold opening action of the movable mold according to the preset mold opening distance. Therefore, the problem that the machine table shakes and vibrates when themovable mold is controlled by the friction force of the machine table to perform nonlinear deceleration emergency stop in the prior art can be solved, so that the service life of the machine table isprolonged, and the injection molding quality is improved.

Description

technical field [0001] The invention relates to a mold opening control method and an injection molding machine thereof, in particular to a mold opening control method for controlling a movable mold to decelerate to stop in a constant deceleration mode and an injection molding machine thereof. Background technique [0002] Generally speaking, during the mold opening process of the injection molding machine, in order to ensure that the injection molding process can be accurately implemented to maintain the molding quality, it is usually required that the movable mold of the injection molding machine stop after the mold opening action is completed. The position can meet certain mold opening accuracy requirements (for example, the mold opening position accuracy should fall within the error range of tens to several centimeters). In the prior art, a common method used to control the stop of the moving mold after opening the mold is to use the maximum friction force that the machin...
