Description

Technical Field

[0001] The present invention relates to the technical field of mold opening for injection molding machines, and in particular to a method and device for synchronous door opening for mold opening for injection molding machines. Background Art

[0002] Currently, there are two types of injection molding machines: two-platen and three-platen. When using a two-platen injection molding machine for semi-automatic production, the electric door must be opened for each mold to accommodate customer product access. The new national standard for injection molding machines synchronizes the opening of the electric door and mold. The host computer outputs a door-opening signal to the electric door driver according to a pre-programmed procedure, and also outputs a mold-opening signal to the mold-opening driver. The electric door driver drives the electric door to open based on the door-opening signal, and the mold-opening driver drives the mold plate to move based on the mold-opening signal, achieving synchronized opening of the electric door and mold opening. When the electric door fully opens, the host computer detects the door-opening signal from the electric door driver and stops outputting the door-opening signal. At this point, the electric door driver stops driving the electric door to open.

[0003] Currently, the speed of the electric door is not easy to adjust, and the function of opening the electric door synchronously with the mold opening cannot be realized. Summary of the Invention

[0083] Example 1

[0084] See also Figure 1 , Figure 1 It is a flow chart of a method for synchronous door opening of an injection molding machine mold opening disclosed in an embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software and / or hardware, and the execution subject can receive relevant information by wired or / and wireless means, and can send certain instructions. Of course, it can also have certain processing functions and storage functions. The execution subject can control multiple devices, such as a remote physical server or cloud server and related software, or it can be a local host or server and related software that performs related operations on a device placed somewhere. In some scenarios, multiple storage devices can also be controlled, and the storage devices can be placed in the same place or different places as the devices. For example Figure 1As shown, the injection molding machine mold opening and door opening synchronous method includes the following steps:

[0085] 101. In response to a movable platen mold opening instruction, a preset maximum mold opening position and a real-time mold opening position are acquired, and an instantaneous mold opening speed is calculated according to the real-time mold opening position.

[0086] When the system receives the instruction to start the mold opening of the injection molding mobile template, it first enters the preparation stage. The preset maximum mold opening position is obtained, which is the position that the electric door should reach when it is fully opened. Based on the mold opening position data collected in real time, the system calculates the current instantaneous mold opening speed. During the mold opening process of the injection molding mobile template from the initial position to the maximum mold opening position, the instantaneous mold opening speed can be calculated by dividing the distance between the different real-time mold opening positions and the initial position by the time from the initial position to the real-time mold opening position. Among them, the mold opening direction and the door opening direction are on the same coordinate axis, and the real-time mold opening position and the real-time door opening position are represented by the numerical value corresponding to the coordinate axis. The initial mold opening position and the initial door opening position are both set to 0, and the distance between the two positions is represented by the difference between the numerical values of the two positions on the coordinate axis.

[0087] 102. Execute the movable platen opening instruction, control the start of the electric door synchronous door opening process, and calculate the synchronous door opening calculation speed.

[0088] After confirming that the dynamic template mold opening instruction is correct, the system starts the synchronous door opening process of the electric door. According to the preset algorithm or conditions, it calculates the speed at which the electric door should open synchronously to ensure coordination with the dynamic template mold opening.

[0089] Specifically, the first door opening position and the second door opening position are collected in real time, and the timestamp of collecting the first door opening position and the timestamp of collecting the second door opening position are obtained respectively; the position difference between the first door opening position and the second door opening position is calculated, and the time difference between the timestamp of calculating the first door opening position and the timestamp of collecting the second door opening position is calculated, and the synchronous door opening calculation speed is calculated according to the position difference and time difference.

[0090] 103. Obtain the door opening end position, and select the door opening end position as the door opening end position or the maximum mold opening position as the door opening end position based on the size relationship between the door opening end position and the maximum mold opening position; and adjust the electric door synchronous opening speed mode according to the real-time mold opening position, the door opening end position, the instantaneous mold opening speed and the shortest deceleration distance for door opening.

[0091] When the door opening cutoff position is less than or equal to the maximum mold opening position, the door opening cutoff position is selected as the door opening end position. When the door opening cutoff position is greater than the maximum mold opening position, the maximum mold opening position is selected as the door opening end position. The preset door opening cutoff position is obtained and compared with the maximum mold opening position. Based on the relative size of the two positions, the system selects one as the door opening end position. If the door opening cutoff position is less than or equal to the maximum mold opening position, the door opening cutoff position is selected; otherwise, the maximum mold opening position is selected.

[0092] After determining the door opening end position, the system will adjust the synchronous door opening speed mode of the electric door according to the real-time mold opening position, door opening end position, instantaneous mold opening speed and the shortest deceleration distance for door opening. The purpose is to ensure that the electric door can decelerate smoothly before reaching the door opening end position to avoid damage to the equipment caused by sudden stop or excessive acceleration.

[0093] Specifically, the synchronous door opening speed mode of the electric door is adjusted according to the real-time mold opening position, the door opening end position, the instantaneous mold opening speed and the shortest deceleration distance for door opening, including: when the door opening end position is selected as the door opening end position, the first difference between the door opening end position and the shortest deceleration distance for door opening is calculated as the first door opening deceleration position, and the size relationship between the first door opening deceleration position and the real-time mold opening position is determined. Further explanation: the shortest deceleration distance for door opening represents the shortest deceleration distance that the electric door can stop when the deceleration is used to decelerate the maximum speed allowed before reaching the door opening end position. When 0≤S 开t <S 开截止 -S 开减 Adjust the electric door synchronous opening speed mode to the first mode; when S is detected 开截止 -S 开减 ≤S 开t <S 开截止 The door synchronous opening speed mode is adjusted to the second mode, and the position between the first door opening deceleration position and the door opening cut-off position is defined as the first real-time door opening position. The door opening speed corresponding to the first real-time door opening position is the door opening calculation speed. When the door reaches the first real-time door opening position, the corresponding instantaneous door opening speed can be obtained, which corresponds to the door opening calculation speed. 开t is the real-time mold opening position, S 开截止 The door opening stop position, S 开减 It is the shortest deceleration distance for door opening.

[0094] When the maximum mold opening position is selected as the door opening end position, the second difference between the maximum mold opening position and the shortest deceleration distance of the door opening is calculated as the second door opening deceleration position, and the size relationship between the second door opening deceleration position and the real-time mold opening position is determined; when 0≤S 开t <S 开模max -S 开减Adjust the electric door synchronous opening speed mode to the third mode; when S 开模max -S 开减 ≤S 开t <S 开模max The synchronous door opening speed mode of the dynamic door is adjusted to the fourth mode, and the position between the second difference and the maximum mold opening position is defined as the second real-time door opening position, and the synchronous deceleration door opening speed corresponding to the second real-time door opening position is recorded as the synchronous deceleration calculation speed; wherein, S 开t is the real-time mold opening position, S 开模max is the maximum mold opening position, S 开减 The shortest deceleration distance for door opening.

[0095] In the above, the first method includes: when the synchronous door opening calculation speed is less than or less than the instantaneous mold opening speed, the synchronous door opening calculation speed is used as the required door opening speed to open the door; when the synchronous door opening calculation speed is greater than the instantaneous mold opening speed, the instantaneous mold opening speed is used as the required door opening speed to open the door; the second method includes: when the synchronous door opening calculation speed is less than or equal to the instantaneous mold opening speed, and the synchronous door opening calculation speed is less than the door opening calculation speed, the synchronous door opening calculation speed is used as the required door opening speed to open the door; when the synchronous door opening calculation speed is less than or equal to the instantaneous mold opening speed, the synchronous door opening calculation speed is used as the required door opening speed to open the door When the synchronous door opening calculation speed is greater than the instantaneous mold opening speed and the synchronous door opening calculation speed is greater than or equal to the door opening calculation speed, the preset electric door opening deceleration is obtained, and the door is opened by deceleration according to the electric door opening deceleration; when the synchronous door opening calculation speed is greater than the instantaneous mold opening speed, and the instantaneous mold opening speed is less than the door opening calculation speed, the door is opened with the instantaneous mold opening speed as the required door opening speed; when the synchronous door opening calculation speed is greater than the instantaneous mold opening speed, and the instantaneous mold opening speed is greater than or equal to the door opening calculation speed, the door is opened by deceleration according to the electric door opening deceleration.

[0096] The third method includes: when the synchronous door opening calculation speed is less than or equal to the instantaneous mold opening speed, the synchronous door opening calculation speed is used as the required door opening speed for opening the door; when the synchronous door opening calculation speed is greater than the instantaneous mold opening speed, the instantaneous mold opening speed is used as the required door opening speed for opening the door; the fourth method includes: when the synchronous door opening calculation speed is less than or equal to the instantaneous mold opening speed, and the synchronous door opening calculation speed is less than the synchronous deceleration calculation speed, the synchronous door opening calculation speed is used as the required speed for opening the door; when the synchronous door opening calculation speed is less than or equal to the instantaneous mold opening speed, and the synchronous door opening calculation speed is greater than or equal to the synchronous deceleration calculation speed, the door is opened by deceleration according to the electric door opening deceleration; when the synchronous door opening calculation speed is greater than the instantaneous mold opening speed, and the instantaneous mold opening speed is less than the synchronous deceleration calculation speed, the door is opened by deceleration according to the electric door opening deceleration.

[0097] Through complex logic and real-time adjustments, the system ensures the synchronization of the electric door and the moving platen opening, thereby improving the efficiency of the injection molding machine and product quality. By precisely controlling the opening speed of the electric door to synchronize with the opening speed of the moving platen, waiting time during the production process can be reduced, thereby shortening the production cycle and improving overall production efficiency. The synchronized door opening method ensures mold stability during the opening and closing process, avoiding product defects caused by asynchronous mold opening and closing, thereby improving product quality and stability.
