Abstract

The invention discloses a method for quickly adjusting mould locking force of a bent-elbow-type injection molding machine, wherein the mould locking force is automatically adjusted and divided into two stages including a primary trial-correction stage and a daily-use stage; at the primary trial-correction stage, a relation of the forward tooth number X of a mould adjusting tooth and the actual mould locking force Y is obtained, until the mould locking force of the whole range is obtained; and at the daily-use stage, the required mould locking tonnage is determined according to actual product requirements, the required forward tooth number X1 is obtained, then mould adjustment is carried out on the tooth X1, and finally mould opening is carried out, and the automatic mould adjustment is completed.

Description

Toggle formula locking force of injection machine fast adjustment method

Technical field

The present invention has saved the clamp force adjustment time greatly, has improved production efficiency.

Background technology

For toggle formula injection machine, after new mould is loaded onto, need product demand to this mould, the adjustment clamping is to apply suitable clamp force to mould.The generation of this clamp force is to realize through adjustment clamping tailgate position relative and solid plate.Be specially, the relative solid plate of tailgate is near, then corresponding same secondary mould, and the clamp force after high-voltage lock mould locking is just big; The relative solid plate of tailgate is far away, corresponding same secondary mould, and high-voltage lock mould locking back clamp force is just little.

The clamp force of toggle formula clamping injection machine commonly used adjustment at present; Be behind installation and fastening good mould, according to the locked mode pressure of technique initialization, through control clamp force guiding mechanism; The adjustment tailgate is to a certain position; Try locked mode then, finish to confirm switch, judge whether and to lock through the high-voltage lock mould that is installed on the clamping mechanism.If can't lock (high-voltage lock mould confirms that switch is not forced into), then behind die sinking one segment distance, adjustment clamp force guiding mechanism makes tailgate move back some distances with respect to solid plate; If can lock (high-voltage lock mould confirms that switch is forced into), then behind die sinking one segment distance, adjustment clamp force guiding mechanism makes tailgate with respect to solid plate some distances of advancing.After last step fine setting,, and then, transfer in or transfer and move back according to the locked mode result at the examination locked mode.Step above repeating, up under current technological parameter, mould can just be by till the locking of injection moulding machine mode-locking mechanism.

Traditional this clamp force adjustment mode, though simple in theory, actual using owing to need repeatedly switch mould and examination locked mode, causes the adjustment time very long; And can adjust the repeated bad of control because the resolution ratio of clamp force guiding mechanism causes, and regular meeting causes automatic clamp force adjustment failure.

Summary of the invention

Technical problem to be solved by this invention be provide in order to overcome the defective that exists in the present toggle formula clamping locking force of injection machine adjustment process a kind of simply, toggle formula locking force of injection machine fast adjustment method fast, accurately.

The present invention for the scheme that technical problem adopted above the solution is:

Toggle formula locking force of injection machine fast adjustment method is characterized by: the automatic adjustment of clamp force is divided into first examination school stage and two stages of daily operational phase,

The first examination school stage comprises following steps:

1) manual matched moulds (high-voltage lock mould confirms that switch is forced into) on earth;

2) manually mode transfer advances, until till can't mode transfer advancing;

3) manually die sinking is a bit of;

4) manually mode transfer advances, and the record mode transfer tooth number of teeth X that advances, and high-voltage lock mould locking then detects actual clamp force Y;

5) repeat 3 to 4 step, obtain the advance relational expression of number of teeth X and actual clamp force Y of mode transfer tooth, up to the clamp force that obtains whole range;

Daily operational phase comprises following steps:

1), confirms needed locked mode tonnage Y1 according to the actual product needs;

2) through the mode transfer tooth that obtains advance number of teeth X and clamp force Y relational expression, obtain the required number of teeth X1 that advances;

3) operator scheme of switching injection machine gets into the automatic mold-adjustment stage to the automatic mold-adjustment pattern;

4) injection machine can automatic die assembly on earth, mode transfer advances then, be transferred to always can't advance till, a bit of distance of die sinking this moment, mode transfer advances the X1 tooth then, automatic mold-adjustment has been accomplished in last die sinking this moment.

Compared with prior art; The invention has the advantages that: only once try the clamp force adjustment in school stage; And later in operational phase; Mould through the examination school carries out the step that the clamp force adjustment process needn't repeat to adjust and try locked mode again, has saved the clamp force adjustment time greatly, has improved production efficiency.

The specific embodiment

Below in conjunction with embodiment the present invention is described further.

The injection molding machine of existing 120 tons of mold clamping forces, try the school earlier for the first time:

2) manually mode transfer advances, until till can't mode transfer advancing;

3) manually die sinking is a bit of;

5) repeat 3 to 4 step, measure and obtain the advance relational expression of number of teeth X and actual clamp force Y of mode transfer tooth, up to the clamp force that obtains whole range, test data is following;

X=5，

Sequence number	The number of teeth of advancing (X)	Locked mode tonnage (Y)
			1	5	9
2	10	19
			3	15	30
4	20	41
			5	25	51
6	30	62
			7	35	71
8	40	80
			9	45	90
10	50	102
			11	55	110
12	60	119

Daily operational phase:

1), sets needed locked mode tonnage 80 according to the actual product needs;

2) through mode transfer tooth the advance number of teeth X and the actual clamp force Y data of test, drawing the required number of teeth of advancing is 40;

4) injection machine can automatic matched moulds on earth, mode transfer advances then, be transferred to always can't advance till, a bit of distance of die sinking this moment, mode transfer advances 40 teeth then, last die sinking, accomplished automatic mold-adjustment this moment, obtained satisfactory locked mode tonnage 80.

In order to dwindle the interval of adjacent clamp force (locked mode tonnage), can each mode transfer tooth number of teeth X that advances be narrowed down to 1, the clamp force data that obtain like this are the most complete, and precision is the highest, can adapt to the production of more products.
