Abstract
The invention discloses a method for solving the problem of die locking force change in a production process of an injection molding machine. A hydraulic pressure sensor is mounted at a system oil pressure part or a die closing oil cylinder of the injection molding machine, wherein the hydraulic pressure sensor is connected with a control system. The solving method comprises the following steps: 1) starting to perform injection molding and finish die closing through the injection molding machine, detecting a die locking force through the hydraulic pressure sensor and automatically generating a standard die locking force in the production process through a control system; 2) judging whether performing die adjusting action according to the current detected die locking force through the control system after finishing die locking, and judging the die adjusting direction according the die locking force if the die adjusting action needs to be made, wherein each die adjusting action is finished before die closing; and 3) repetitively and circularly executing the step 1 and the step 2 through action of each die in an injection molding process of the injection molding machine. The method has the beneficial effect that the injection molding machine is capable of automatically adjusting the die and finally meeting the requirement of the die locking force when the die locking force deviates in the production process of the injection molding machine, so that the manual adjustment of the die is not required completely.
Description
Technical field
The invention belongs to injection machine control technology field, especially relate to the solution of clamp force variation issue in a kind of injection machine production process.
Background technology
In injection machine production process, because long continuous operation causes variation mechanically, make clamp force that variation occur, this clamp force or become large or change.Due to the variation of clamp force, make the product that final production goes out occur overlap or lack material.
Therefore,, in order to solve because the variation of clamp force causes product problem, need in the production process of every mould, all keep clamp force in certain scope.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of complete solution without clamp force variation issue in the injection machine production process of artificial mode transfer is provided.
The object of the invention is to complete by following technical solution, hydraulic pressure sensor is installed at the system oil pressure on injection machine or mould oil cylinder place, pass, and this hydraulic pressure sensor is connected with control system; This solution comprises the steps:
1): injection machine starts injection moulding and pass mould is complete, detects clamp force, and automatically generate the standard clamp force in production process by control system by hydraulic pressure sensor;
2): after locked mode, control system, according to detecting that current clamp force judges whether to do mode transfer action, judges mode transfer direction according to clamp force as needs do mode transfer action; Each mode transfer action completes at Guan Moqian;
3): the every mould in injection machine injection moulding process moves all repetitive cycling execution step 1 and step 2.
As preferably, the mode transfer action of described step 2 comprises as follows:
2-1): determine current clamp force and be above standard in clamp force in limited time, before next mould closes mould, die holder is adjusted and moved back N fixed grating number or N set time second;
2-2): determine current clamp force lower than prescribing a time limit under standard clamp force, before next mould closes mould, die holder is transferred in to N fixed grating number or N set time second;
2-3): determine current clamp force within the scope of the bound of standard clamp force, do not need to do mode transfer action.
Beneficial effect of the present invention is: make injection machine in process of production can automatic mold-adjustment in the time that deviation appears in clamp force finally arrive the requirement of clamp force, completely without artificial mode transfer, realize injection machine stability in process of production.
Brief description of the drawings
Fig. 1 is control flow chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction: as shown in Figure 1, hydraulic pressure sensor is installed at system oil pressure or the pass mould oil cylinder place of the present invention on injection machine, and this hydraulic pressure sensor is connected with control system; This solution comprises the steps:
1): injection machine starts injection moulding and pass mould is complete, detects clamp force, and automatically generate the standard clamp force in production process by control system by hydraulic pressure sensor;
2): after locked mode, control system, according to detecting that current clamp force judges whether to do mode transfer action, judges mode transfer direction according to clamp force as needs do mode transfer action; Determine current clamp force and be above standard in clamp force in limited time, before next mould closes mould, die holder is adjusted and moved back a fixed grating number or a set time; Determine current clamp force lower than prescribing a time limit under standard clamp force, before next mould closes mould, die holder is transferred in to a fixed grating number or a set time; Determine current clamp force within the scope of the bound of standard clamp force, do not need to do mode transfer action; Each mode transfer action completes at Guan Moqian.
3): the every mould in injection machine injection moulding process moves all repetitive cycling execution step 1 and step 2.
Be understandable that, for a person skilled in the art, technical scheme of the present invention and inventive concept be equal to replacement or change the protection domain that all should belong to the appended claim of the present invention.
