Abstract
The utility model relates to an anti-collision molding die, and mainly solves the technical problem that a die is damaged seriously because a thimble is broken in drawing or is caused to puncture a molding cavity due to easy collision of the existing molding die. The molding die has the technical scheme that a travel switch is arranged on a movable module and is connected with a control system of an injection molding machine, and a contact head of the travel switch can engage and close a circuit when a thimble plate is ejected or reset. The molding die provided by the utility model has the benefits as follows: the travel switch is arranged on the movable module, so that the contact head of the travel switch is forced to close the circuit at the time of resetting of the thimble plate when the demolding of an injection molding part is finished; as a result, only when the circuit is closed, the control system of the injection molding machine can give a command to control the movable module to perform die closing, and when the circuit of the travel switch is disengaged, the control system cannot control the movable module to perform die closing, thereby avoiding the collision of the die during the die closing so as to prevent the thimble from being broken in drawing or from puncturing the molding cavity; and therefore, the use safety of the die is ensured and the service life of the die is prolonged.
Description
Technical field
The utility model relates to a kind of injection mold, relates to a kind of crashproof mould in particular, is mainly used in die industry.
Background technology
Mould all is through thimble moulding to be ejected after injection mo(u)lding is accomplished mostly, thereby realizes the automatic demoulding of moulding.And the control system of injection machine is behind the moulding automatic demoulding, i.e. the dynamic and static module matched moulds of start-up control mould once more, and this moment; Whether ejector retainner plate on the dynamic model piece and thimble reset, and the control system then can't judge, therefore; There is certain potential safety hazard, in time do not reset like ejector retainner plate and thimble, and when suffering by force matched moulds; Very easily hit the mould phenomenon, cause thimble to break or push up the consequence of serious mold damage such as bad die cavity.
Summary of the invention
Be prone to hit mould in order to solve existing mould, cause thimble to break or push up the technical problems such as consequence of serious mold damage such as bad die cavity; The utility model provides a kind of mould of crashproof mould, and this mould can effectively prevent when ejector retainner plate and thimble do not reset, matched moulds phenomenon by force not to take place, and the intellectuality that has improved injection machine avoids hitting mould, guarantees the safety in utilization of mould.
For solving above technical problem; The technical scheme that the utility model is taked is a kind of mould of crashproof mould; It includes quiet, dynamic model piece, in the dynamic model piece, is provided with the ejector retainner plate of slippage up and down, on described dynamic model piece, is provided with travel switch; The trip switch links to each other with the control system of injection machine, and the contact of described travel switch can be connected and closed circuit when ejector retainner plate ejects and reset.
Further; On described dynamic model piece, be provided with installing hole; This installing hole is arranged on the substrate of dynamic model piece; Described travel switch is fixed in this installing hole and the contact of travel switch places on the plane of substrate, and described ejector retainner plate is when resetting and the contact closure circuit that fits and order about travel switch of the plane of substrate.
Further, the both positive and negative polarity of described travel switch links to each other with binding post through lead, and this binding post is fixed on the sidewall of substrate, and the control system is electrically connected with binding post through lead.
The beneficial effect of the utility model is on the dynamic model piece, travel switch to be set, when minute mould, and the ejector retainner plate slippage that makes progress, at this moment; The contact of travel switch unclamps disconnecting circuit, and thimble ejects moulding, and ejector retainner plate resets when the moulding demoulding is accomplished; Just can oppress the contact closure circuit of travel switch, only when closing of circuit, the control system of injection machine just can send commands for controlling dynamic model piece matched moulds; When the circuit of travel switch broke off, the control system can not control dynamic model piece matched moulds, so just can effectively avoid when matched moulds, hitting mould; Break thimble or thimble pushes up bad die cavity, guarantee the safety in utilization of mould, prolong the service life of mould.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Extremely shown in Figure 3 like Fig. 1; The utility model is a kind of mould of crashproof mould; It includes quiet, dynamic model piece 1,2; In dynamic model piece 2, be provided with the ejector retainner plate 3 of up and down slippage, be prone to hit mould, cause thimble to break or push up the technical problems such as consequence of serious mold damage such as bad die cavity in order to solve existing mould; On described dynamic model piece 2, be provided with travel switch 4, the trip switch 4 links to each other with the control system 5 of injection machine, and the contact 41 of described travel switch 4 can be connected and closed circuit when ejector retainner plate 3 ejects and resets; Travel switch 4 is set on dynamic model piece 2, when minute mould, ejector retainner plate 3 upwards slippages, at this moment; The contact 41 of travel switch 4 unclamps disconnecting circuit, and thimble ejects moulding, and ejector retainner plate 3 resets when the moulding demoulding is accomplished; Just can oppress contact 41 closed circuits of travel switch 4, only when closing of circuit, the control system 5 of injection machine just can send commands for controlling dynamic model piece 2 matched moulds; When the circuit of travel switch 4 broke off, control system 5 can not control dynamic model piece 2 matched moulds, so just can effectively avoid when matched moulds, hitting mould; Break thimble or thimble pushes up bad die cavity, guarantee the safety in utilization of mould, prolong the service life of mould.
In the present embodiment; Installation for ease of travel switch 4; On described dynamic model piece 2, be provided with installing hole 211; This installing hole 21 is arranged on the substrate 21 of dynamic model piece 2, and described travel switch 4 is fixed in this installing hole 211 and contacts 41 of travel switch 4 place on the plane of substrate 21, and described ejector retainner plate 3 is when resetting and the contact closure circuit that fits and order about travel switch 4 of the plane of substrate 21.On the substrate 21 of dynamic model piece 2, be arranged on installing hole 211 and travel switch 4 is fixed in the installing hole 211; Like this when ejector retainner plate 3 resets and substrate 21 back that fits just can oppress the contact 41 of travel switch 4; Order about the travel switch 4 closed loops that form; Thereby control system 5 just can send commands for controlling dynamic model piece 2 matched moulds, avoids hitting the mould phenomenon.
In the present embodiment; Link to each other with the control system 5 of injection machine for ease of travel switch 4, the both positive and negative polarity of described travel switch 4 links to each other with binding post 6 through lead, and this binding post 6 is fixed on the sidewall of substrate 21; Control system 5 is electrically connected with binding post 6 through lead; Travel switch 4 links to each other with the control system 5 of injection machine through binding post 6, and when installation mold, the circuit of being convenient to travel switch 4 connects like this.
The foregoing description should not be regarded as the restriction to the utility model, but any improvement of doing based on the spirit of the utility model, all should be within the protection domain of the utility model.
