Embodiment Construction

[0023] The following is an example of processing the linear displacement measurement data of the clamping thrust seat of a certain type of electric injection molding machine relative to the rear template, combined with Figure 1 to Figure 5 The present invention is further described.

[0024] The method for processing the linear displacement measurement data of the injection molding machine clamping thrust seat of the present invention has the following steps:

[0025] (1) Obtain the measured linear displacement data series and the corresponding time data series, determine the total length of the data series, take a piece of valid data, and assign a serial number to each data. In this embodiment, 17494 effective displacement data and corresponding time data are taken, and the serial numbers of the data are 1~17494.

[0026] (2) Take the time data series as the horizontal axis value and the linear displacement data series as the vertical axis value to display the displacement-...

Abstract

The invention discloses an injection molding machine die assembly thrust seat linear displacement measuring data processing method. The method includes: acquiring measured linear displacement data series and corresponding time data series, determining the total length of the data series, taking one section of effective data, allocating a serial number to each datum, using the time data series as horizontal axis value and the linear displacement data series as longitudinal axis value, displaying a displacement-time curve, and calculating the average value of all effective displacement data; traversing the displacement data series, segmenting circulation by using the displacement location closest to the average value as the starting point and in the displacement ascending direction, and recording the displacement vale, time value and data serial number information of the location; traversing the displacement data series, counting circulation number and datum number in each circulation according to the circulation segmenting point, searching for the maximum displacement valve and die assembly displacement value of each circulation, and calculating stroke value. The method has the advantages that relations among data are found according to measured discrete data series, and the motion features of the thrust seat can be analyzed.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing and measurement, and relates to a data processing method for linear displacement measurement of mechanical motion, in particular to a data processing method for linear displacement measurement of a mold clamping thrust seat of an injection molding machine. Background technique [0002] In the injection molding machine, the thrust seat makes a reciprocating linear motion, and drives the toggle mechanism to realize the functions of mold opening, mold clamping, and mold locking of the moving template. The motion accuracy of the thrust seat determines the motion accuracy of the moving template, which affects the precision and quality of the injection molded products. Therefore, in engineering, the linear displacement of the thrust seat is measured to understand and control its motion. However, the current application of linear displacement measurement data is limited to direct application, lack...
