Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of mold with the rubber plug structure that can control three pieces of template order strippings as shown in Figure 1 and Figure 2, wherein
Including successively as the panel of basic framework 100, solid plate 200, push plate 300, moving template 400 and bottom plate 500, wherein in cover half
Plate 200, push plate 300 are provided with rubber plug structure 600 between moving template 400, and the quantity of the rubber plug structure has 4, and is distributed in mould
The quadrangle of tool.Wherein as shown in figure 3, the rubber plug structure includes the rubber plug set 610 being mounted in moving template and is set in rubber plug
Set 610, push plate 300, the rubber plug 620 in moving template 400；The fixed form of rubber plug set 610 are as follows: one is offered on solid plate
The shape of the stepped hole of perforation, rubber plug set 610 is adapted to the stepped hole, and when installation, rubber plug inserting packs into stepped hole and consolidated
The panel being scheduled on solid plate is pushed down, and is fixed on solid plate 200 with realizing.Wherein the structure of rubber plug 620 is divided into sleeve in glue
First 621 in plug sleeve 610, second 622 be set in push plate, and the third portion being set in moving template 400
623。
Wherein, in order to make solid plate 200, push plate 300, can be according to moving template → push plate → cover half between moving template 400
The sequence of plate successively demoulds, and the frictional force between first 621 of rubber plug and rubber plug set 610 is greater than second between push plate
Frictional force, and the frictional force between second 622 and push plate 300 is then greater than the friction between third portion 623 and moving template 400
Power.To realize above scheme, wherein the material of rubber plug set is silicon rubber, and first cylinder outer rim is then enclosed with tack silicon
Glue；Material at second is butyl rubber；The material in third portion is nylon, and makees annular knurl processing on nylon to enhance nylon
Frictional force between solid plate.Meanwhile rubber plug volume first and rubber plug set, second with push plate, third portion and moving template it
Between frictional force be sequentially reduced, and the enough third portions of the frictional force size between third portion and moving template by moving template from bottom plate
It pulls open.And the utilization of rubber plug structure, but also the utility model eliminates thimble and spacing board (square iron, mould in traditional moulds
Foot), to be that mold is provided with bigger design space.
600 working principle of rubber plug structure are as follows: when product, which is molded completion molding, to be needed to demould, pull rod (does not show in figure
It acts out), pulls the panel 100 being attached thereto, moving template, push plate, solid plate are under the action of rubber plug structure at this time, with panel
It acts together, to complete to demould for the first time.Wherein the process of demoulding is also that oblique in mold is taken out 700 from product table for the first time
The process that face detaches, and when it is oblique take out 700 and detach to setting position when, tiltedly take out with moving template and no longer there is relative displacement, at the same
It tiltedly takes out and one is generated with pull rod to the identical pulling force of panel size to the moving template contacted.And as pull rod continues outward
It draws, pulling force increases with it.When pull rod to the pulling force of panel be greater than the third portion 623 of rubber plug to the frictional force of moving template and less than the
When frictional force between two 622 and push plate 300, the third portion 623 in moving template starts to be detached from moving template, when third portion
After completely disengaging moving template, second of demoulding is completed.After the completion of second demoulds, moving template 623 has moved to setting position
It sets, and does not continue to move；Pull rod continues movement pulling panel at this time, and moving template forms one and pull rod drawing to push plate at this time
The identical reaction force of power, when the reaction force is greater than second frictional force between push plate, second 622 of rubber plug is opened
Begin to be detached from push plate, after completely disengaging push plate 300 for second, third time demoulding is completed.The moving template of rubber plug structure completion at this time →
The successively demoulding of push plate → solid plate.
First for rubber plug is mountable to position when sleeve is into rubber plug set, prevents because of rubber plug and rubber plug
The case where between set because inside can not be arranged in place there are air.The air of a perforation is offered on the top of rubber plug set
Channel 611.Offer the compatible exhaust duct (not shown) of the air duct on panel 100 simultaneously.
Preferably, when rubber plug works, in order to enable rubber plug accurately to playback, prevent first of rubber plug from entering band
Push plate, second of rubber plug enter the appearance that the rubber plugs such as moving template do not enter into corresponding position situation, and first of rubber plug
621, second 622, third portion 623 be the stair-stepping cylindrical body that successively reduces of cross section.Rubber plug leads to, on solid plate simultaneously
It is adapted for being arranged the duct of rubber plug with rubber plug on, push plate, moving template.
Its working principle is that: the stair-stepping rubber plug successively reduced can guarantee in mold clamping, and first will not be into
Enter into push plate, second will not enter in moving template, to ensure that the precise positioning precisely in a mold of rubber plug.
In clamping process, because first and second is all rubber material, and first and second in frictional force
Under the action of can have certain deformation, and be finally stacked at die joint, so that between solid plate and push plate；Push plate and dynamic model
It cannot be bonded well between plate.And to solve the above-mentioned problems, second junction is provided with the first mistake at first
Aqueduct 624 is provided with the second lead-over groove 625 in the junction of second and third portion, wherein First Transition slot and the second transition
Slot is all annular groove, and when mold is in molding state, First Transition slot 624 is between solid plate 200 and push plate 300
At die joint, the second lead-over groove 625 is located at the die joint of push plate 300 and moving template 400.
Its working principle is that: when first and second, deformation occurs and to first and second under the action of frictional force
When the accumulation of the junction in the junction in portion and second and third portion, First Transition slot 624 is given respectively with the second lead-over groove 625
It is deposited in first of junction and second deflection slot milling, so that reducing first and second is deposited in connection
Influence of the deflection at place to mold clamping is can tightly to paste between solid plate and push plate, push plate and moving template in molding
It closes.
