Abstract
The invention discloses an automotive injection mold switching ware. The switching ware comprises a pull rod, a pull rod screw, a T-shaped plug pin, a locking seat, a spring, a rubber sleeve, an adjusting screw and an upper ejector plate and a lower ejector plate of a mold, wherein the pull rod is inserted from the upper part of the upper ejector plate and penetrates to the lower ejector plate; the spring is arranged below the pull rod and located between the upper ejector plate and the lower ejector plate; the upper end of the pull rod is connected with the locking seat through the T-shaped plug pin; the plug pin is fixed on a fixed mold plate of a mold; a hole is formed in the bottom of the pull rod; the pull rod screw is arranged at the lower ejector plate; the head of the pull rod screw is inserted into a pull rod screw hole. According to the switching ware, the clamping force of a cylinder and the plug pin on the locking seat can be adjusted through selecting different elastic elements and adjusting the deformation quantity of the elastic elements, so that the mold locking force of the novel injection mold switching ware is adjusted; the switching ware is simple in structure and has high practicality.
Description
Technical field
The present invention relates to automobile injection mold field, particularly relate to a kind of automobile injection mold shutter.
Background technology
The effect of mould open/close device is to be mainly used for increasing solid plate, Resistance of opening mould between moving platen, guarantee that runner plate and panel and solid plate open before opening prior to solid plate and moving platen, at design three template dies, when Double-ejection etc. need sequence to control the mould of die sinking order, can on die sinking face, design shutter.
Mould open/close device kind mainly contains two kinds: resin shutter, claim again nylon shutter and spring shutter, also developed recently magnetic on/off device, the most frequently used is nylon shutter, nylon shutter is mar proof and poor heat resistance not only, and clamp force is little, so the result of use of nylon shutter on large mold is not good.
Summary of the invention
Object of the present invention, provides a kind of structure of automobile injection mold shutter, still uses nylon shutter, solves clamp force pin, and the poor problem of resistance to wear, and the present invention is simple in structure, not easy to wear.
An automobile die shutter, comprises pull bar, pull bar screw, the latch of T shape, locking bed, spring, gum cover and adjustment screw, and the upper ejector plate of mould, lower liftout plate.
Described pull bar inserts from the top of upper ejector plate, extend through lower liftout plate always, spring is set below pull bar, spring is between upper ejector plate and lower liftout plate, the upper end of described pull bar is connected with locking bed by T shape latch, fixes this latch on the solid plate of mould, and pull bar bottom arranges porose, lower liftout plate be provided with pull bar screw, pull bar screw head inserts in pull bar screw hole.
Adjustment screw is fixed on gum cover, by the adjustment of adjustment screw, makes the frictional force between template and gum cover change size, thereby has the effect of buffering template.
When tightening adjustment screw, can make gum cover compression, produce the frictional force near pull bar, on the contrary frictional force can reduce, after injection molding completes, during die sinking, regulate the frictional force between solid plate and gum cover, can guarantee correct die sinking order.
An optimal technical scheme, described gum cover material, except nylon, can be also rubber, polyurethane.
An optimal technical scheme, described locking bed is cuboid.
The invention has the beneficial effects as follows: the present invention can be by choosing different flexible members and regulating the deformation quantity of this flexible member to regulate cylinder on locking bed and the engaging power of latch, thereby regulate the clamp force of this novel die shutter, it is simple in structure, have compared with high practicability, easily realize.Shutter simple in structure, regulates easily, reliable in action, and design attitude is flexible, thereby applies in injection mold structure, and it is simple in structure, easy for installation, and serviceability is good.
Accompanying drawing explanation
Fig. 1 is the positional structure schematic diagram in the mould of automobile injection mold shutter of the present invention place
In figure, 1 is pull bar, and 2 is stop pin, and 3 is spring, 4 is upper ejector plate, and 5 is lower liftout plate, and 6 is stop piece, 7 for ejecting yoke plate, and 8 is pull bar screw, and 9 is push rod, 10 is core plate, and 11 is bottom plate, and 12 is right mould pin, 13 is left mould pin, and 14 for wearing a hole, and 15 is gum cover, 16 is adjustment screw, and 17 is locking bed.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
An automobile die shutter, comprises pull bar, pull bar screw, the latch of T shape, locking bed, spring, gum cover and adjustment screw, and the upper ejector plate of mould, lower liftout plate.
Described pull bar inserts from the top of upper ejector plate, extend through lower liftout plate always, spring is set below pull bar, spring is between upper ejector plate and lower liftout plate, the upper end of described pull bar is connected with locking bed by T shape latch, fixes this latch on the solid plate of mould, and pull bar bottom arranges porose, lower liftout plate be provided with pull bar screw, pull bar screw head inserts in pull bar screw hole.
Adjustment screw is fixed on gum cover, by the adjustment of adjustment screw, makes the frictional force between template and gum cover change size, thereby has the effect of buffering template.
When tightening adjustment screw, can make gum cover compression, produce the frictional force near pull bar, on the contrary frictional force can reduce, after injection molding completes, during die sinking, regulate the frictional force between solid plate and gum cover, can guarantee correct die sinking order.Described gum cover material, except nylon, can be also rubber, polyurethane.Described locking bed is cuboid.
The foregoing is only in another embodiment embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
