Description

The neutron control method of injection machine

Technical field

The present invention relates to a kind of neutron control method of injection machine.

Background technology

Neutron on the injection machine is loosed core exactly; include the advance and retreat action; it is exactly an action on injection machine dynamic model or the cover half; or at dynamic model or at cover half, be to decide according to concrete actual product and mould structure, generally use hydraulic oil cylinder driving; slide block in the control mould moves back and forth; in the whole injection machine formed product cycle, neutron need move back and forth on different opportunitys, satisfied the formed product demand.

In the existing injection machine, the control method of neutron there are following three kinds:

1. on the existing common injection machine, the neutron control method is as follows: neutron advances: only be chosen in " before the matched moulds ", " in the matched moulds ", " matched moulds eventually ", these three kinds action node modes when " in the matched moulds " mode of selection, can be set concrete neutron precession and do the position; Neutron moves back: only be chosen in " before the die sinking ", " in the die sinking ", " die sinking eventually ", these three kinds action node modes when " in the die sinking " mode of selection, can be set concrete neutron deactuate and do the position.

2. when multigroup neutron (for example neutron A, neutron B, neutron C, neutron D), need when the action of same position, follow the industry rule of acquiescence, that is: neutron advance for: neutron A → neutron B → neutron C → neutron D, neutron move back and are neutron D → neutron C → neutron B → neutron A.→

3. at every group of neutron advance and retreat, all must enter the end or the end of falling back on, can't in the process of neutron advance and retreat, its action be stopped, just can't carrying out the meta control (control in centre position) of neutron.

3 above neutron control methods, very traditional, relatively simple, control logic is simple, and injection machine but needs to produce various products in actual production, can run into various moulds, be multifarious, therefore, this simple neutron control method is difficult to satisfy complicated mould and product demand.

In growing mould industry, the control method and the control logic of neutron are had higher requirement.The injection machine manufacturer of main flow often all is that the client proposes a new neutron control requirement in the market, and producer changes by program, satisfies a client's demand.Just the client comes a requirement, and producer just does one, though be the demand that has satisfied the client, because the systematic planning of neither one has caused the puzzlement in the repetition of software systems work, managerial confusion and the client's use.A lot of injection machine manufacturers also want to be designed to powerful what is called " omnipotent neutron ", try hard to satisfy client's the overwhelming majority's specialities demand.But often also be unable to do what one wants very much to do, never realize.

Summary of the invention

Technical problem to be solved by this invention is the neutron control method that a kind of injection machine is provided for the above-mentioned deficiency that overcomes prior art, make the more systematization with better function of neutron, user's operation is simpler more effective, can satisfy complicated mould and product demand, and promote the cost performance of injection machine.

The present invention solves the problems of the technologies described above the technical scheme that is adopted to be respectively:

1. at first in the background technology description, solution of the present invention is as follows:

1) the conventional motion flow of injection machine is as follows: matched moulds → seat advances → injects → penetrate before pressurize → storage move back → penetrate after storing → storage move back → cool off → seat stand moves back → die sinking → thimble advances → thimble moves back → next circulation;

2) the present invention, be to design following 13 action nodes in the injection machine motion flow of above routine: (node 10), die sinking whole (node 11), thimble advance end (node 12) in (node 9), the die sinking before (node 8), the die sinking behind (node 7), the storing before (node 6), the storing after (node 5), the pressurize before (node 4), the pressurize before (node 2), matched moulds whole (node 3), the injection in (node 1), the matched moulds before the matched moulds, thimble moves back end (node 13);

3) with 13 action design of node in the conventional motion flow of injection machine, it is as follows to gather flow process:

Before the matched moulds, in (node 1) → matched moulds, (node 2) → matched moulds eventually, before (node 3) → seat advances → injects, before (node 4) → injection → pressurize, after (node 5) → pressurize → pressurize, (node 6) → storage before penetrate move back → storing before, behind (node 7) → storing → storing, penetrate after (node 8) → storage move back → cool off → seat stand moves back → die sinking before, in (node 9) → die sinking, (node 10) → die sinking eventually, (node 11) → thimble advances → and thimble advances end, (node 12) → thimble moves back → and thimble moves back end, (node 13) → next circulation;

4) action of neutron advance and retreat can gather in the flow chart above-mentioned, in the action node of 13 planning, selects arbitrarily.

By this solution, solved the single defective of neutron action node, 13 open action node options provide powerful selection space to the user.

2. at second in describing in the background technology, promptly control on the advance and retreat order of a plurality of neutrons, solution of the present invention is as follows:

1) order of neutron A, neutron B, neutron C, neutron D advance and retreat can be set respectively

Neutron advances order and sets:? →? →? →?

Neutron moves back order and sets:? →? →? →?

2) user can fill in suitable neutron order according to the mould and the product demand of reality

3) by this solution, solved at same operating position, the defective that neutron advance and retreat order is single, the open any set-up function of neutron sequence of movement provides powerful selection space to the user.

3. at the 3rd in the background technology description, promptly on the advance and retreat position of the single group of control neutron, solution of the present invention is as follows:

Whether 1) neutron advances or moves back, can select " middle bit function " to use, and the optional time of selecting of middle bit function/Stroke Control mode, and is specific as follows:

Does neutron A advance meta? select: 0=uses without 1=

Control mode? select: 0=time 1=stroke

Does neutron A move back meta? select: 0=uses without 1=

Control mode? select: 0=time 1=stroke

2) if a plurality of neutrons are arranged, for example neutron B, C, D then can catch up with and state the identical setting of neutron A

3) by this solution, can realize whether neutron in the process of advancing or moving back, needs the Halfway Stopping function, and can select the condition of Halfway Stopping that promptly control mode is by time or stroke.

Compared with prior art, the invention has the advantages that:

Present invention can be implemented in the injection machine complete machine do action flow process, the neutron advance and retreat can be chosen in action arbitrarily in above 13 nodes.

Multigroup neutron can any selection sequence of movement on same operating position.

In the process of neutron advance and retreat, can select the Halfway Stopping function according to demand.

By above solution, enriched the neutron control function of injection machine greatly, thereby made the injection moulding function satisfy mould and product demand more complicated and changeable, promoted the class of whole complete machine.

The specific embodiment

The present invention will be further described below in conjunction with example.

The client has a mould, requires following action logic:

Neutron C advances → neutron B advances → matched moulds → neutron A advances → inject → pressurize → neutron A moves back → storing → cooling → neutron C move back meta → neutron B move back meta → die sinking → neutron C move back → neutron B moves back → demoulding advances → demoulding moves back → ... circulation once more.

This is a very complicated neutron control requirement, on common injection machine before, can't finish at all, needs the special program development by injection machine manufacturer, could realize.But the construction cycle is long, the middle subprogram of customization, and versatility is poor, produces new product if desired, also needs to develop once more.

According to the neutron control method of injection machine of the present invention, the controller of injection machine then can be set by simple parameters, can realize complicated neutron control requirement.

1) setting the sequence of movement that neutron advances is: C → B → A;

2) setting the sequence of movement that neutron moves back is: A → C → B;

3) set neutron C and move back the meta use;

4) set neutron B and move back the meta use;

5) setting the action node that neutron A moves back is, after the pressurize (node 6);

6) set other relevant action parameters (, not described) here because of irrelevant with the present invention.

By above setting, can satisfy the moulding demand of client's product fully.
