Description

A kind of hook of automobile door plate bracket mould goes out component

Technical field

The utility model relates to technical field of mold, and in particular to automobile door plate bracket mould.

Background technique

As shown in Figure 1, being a kind of automobile door plate bracket (in attached drawing shown in label 100), for installing the vapour such as automobile door plate Vehicle part.There is mounting groove (in attached drawing shown in label 101) on the inside of automobile door plate bracket, mounting groove (is marked by convex edge in attached drawing Shown in 102) it is formed towards automobile door plate bracket inner bulge, mounting groove and convex edge form overhead structure, and due to the barb knot Structure is located on the inside of automobile door plate bracket, cannot directly break off relations from inside.Therefore the molding and unhook of mounting groove and convex edge are automobiles The difficult point of door-plate bracket mould design.In addition, automobile door plate stent length is larger, when demoulding, is easy unbalance stress, causes to deform Or demoulding has some setbacks.

Therefore, how design vehicle door-plate bracket mould, can smoothly break off relations, be that those skilled in the art are urgently to be resolved A problem.

Utility model content

One of the utility model is designed to provide a kind of one step of energy and breaks off relations, and structure is simple, demoulds smoothly automobile The uncoupling rigging of door-plate bracket mould.

To be designed to provide a kind of structure simple for another of the utility model, and linkage is reliable, and break off relations smoothly car door The hook of board mount mold goes out component.

To achieve the above objectives, a kind of the technical solution adopted in the utility model are as follows: unhook of automobile door plate bracket mould Mechanism, it is characterised in that: go out component including fixed block, ejection assembly and hook；

The fixed block fixed setting, for installing and supporting the ejection assembly and the hook to go out component；

The ejection assembly includes actuator, connecting rod and ejection slider, and the connecting rod, which is arranged obliquely and slides, to be set It is placed in the fixed block, the actuator is set to the connection rod rear end, for driving the connecting rod along the fixation Block sliding, the ejection slider are fixedly installed on the connecting rod front end, and the ejection slider front end is provided with forming part, described Forming part includes molding protrusion, and for the molding protrusion for forming mounting groove, the forming part rear end is provided with resigning portion, described Resigning portion goes out component for accommodating the hook, and the resigning portion rear end is provided with linkage portion, and the linkage portion is described for linking Hook goes out component；

It includes that guide rod and hook go out sliding block that the hook, which goes out component, and the guide rod is arranged obliquely and is fixedly installed on described On fixed block, the angle that tilts down of the guide rod tilts down angle slightly larger than the connecting rod, and the hook goes out sliding block It is slideably positioned on the guide rod, the hook goes out slip front and is provided with insertion section, and the insertion section enters the resigning portion And gap is convexed to form with the molding, for forming convex edge, the insertion section front end is provided with barb, and the barb is close to institute Convex edge upper surface is stated, the insertion section rear end is provided with follower, and the linkage portion is close to the follower, described for driving Hook goes out sliding block and slides along the guide rod.

As an improvement, it is two groups that the ejection assembly and the hook, which go out component, and it is interspersed in the fixed block two Side.Enable a secondary mold to form two automobile door plate brackets simultaneously, improves shaping efficiency.

Further, the fixed block is multiple, and is spaced apart along the length direction of automobile door plate bracket；It is corresponding every Two groups of staggered connecting rods and the guide rod are provided on a fixed block.Due to automobile door bracket compared with It is long, thus ejection slider and hook go out sliding block length it is also larger, the setting of multiple fixed blocks, connecting rod and the guide rod, energy It acts on ejection slider simultaneously and hook goes out on sliding block, make to be more uniformly stressed, can more smoothly push ejection slider and hook to go out Sliding block, to more smoothly complete demoulding.

Preferably, the ejection slider passes through chamfering or rounding processing with the contact edge that the hook goes out sliding block. It is avoided that ejection slider and hook go out sliding block and interfere by chamfering or rounding processing, makes to break off relations more smooth.

Further, the ejection assembly further includes signal feedback device, and the signal feedback device includes riser, cross Bar, bulge loop and travel switch, the riser are fixedly installed in the connecting rod, and the cross bar is fixedly installed on the riser On, the cross bar and the connecting rod are arranged in parallel, and the bulge loop is fixedly installed on the cross bar, and the travel switch is fixed It is set on the actuator, when the cross bar slides, the bulge loop can extrude the button of the travel switch, for transmitting position Shifting signal.By above structure, it can simply realize that signal is fed back, to carry out demoulding work in next step, and structure can It leans on, it is at low cost.

Preferably, the actuator is air cylinder device or electromagnet apparatus, for driving the connecting rod to slide.It is above-mentioned Two kinds of driving methods are all that large mold is common, are had the advantages that simple and reliable.

It should be noted that other core pullings of mold and demoulding mechanism are first complete before the uncoupling rigging movement of this programme At stripping action, make outer workpiece that there is vacancy.The uncoupling rigging movement of this programme later, completes unhook work.

The key point of the utility model is that " angle that tilts down of the guide rod is slightly larger than the downward of the connecting rod Tilt angle ".Specifically, ejection slider is movable obliquely, drives hook to go out sliding block inclined slide downward, due to guide rod inclination angle It spends bigger, so that hook goes out the trend that sliding block has a flip-over compared to ejection slider, i.e., insertion section and forms protrusion Dislocation, and since barb is arranged, enabling barb by workpiece, from the forming part of ejection slider " stingy " gets off, to complete to break off relations Movement.

Compared with the prior art, the advantages of the utility model are:

1, this programme is by the driving of actuator, can be completed ejection assembly and hook go out two components of component linkage it is dynamic Make, can a step break off relations, simplify mould structure, reduce die cost.

2, since Workpiece length is larger, the package power between ejection slider is also larger, and hook goes out the wound of sliding block New design, can by workpiece, " stingy " gets off from ejection slider, make to demould more smooth.
