Abstract
The invention discloses an injection mould ejecting device with a continuously-changeable ejecting distance. The device is characterized by comprising a wedged slide block, a slide rail, an ejector plate and a slide block return spring, wherein the slide block and the ejector plate are respectively arranged at two sides of the wedged slide block; the front side of the ejector plate is fixedly provided with at least two ejector pins on which an ejector pin return spring is sleeved; and the reverse side of the ejector plate is provided with a slope which is in contact with the wedged slide block and relatively slides along the wedged slide block. The injection mould ejecting device has the beneficial effects that the ejector plate with the ejector pins slides on the wedged slide block, and the distance that products are ejected by the ejector pins can be continuously changed, so that the requirement for different ejecting degrees is met; the ejector pins are sleeved with the ejector pin return spring, which is beneficial to the smooth return of the ejector plate, and unnecessary parts are omitted by direct sleeving so that convenience in mounting is realized; and the tip end of the wedged slide block is connected with the slide block return spring, which is capable of assisting returning of the wedged slide block.
Description
Technical field
The present invention relates to a kind of liftout attachment of injection mold, but be specifically related to a kind of distance continually varying injection mold liftout attachment that ejects.
Background technology
Injection mold generally comprises male model plate, caster, male model Renhe mother module core.In the forming process, male model plate, male model Renhe mother module core and caster are closed, form die cavity; Injection machine is injected the plastic cement of molten state in mould through nozzle; The plastic cement of molten state gets into die cavity through running gate system, gets into cooling stage through packing stage then, after the goods cooling in the die cavity, the curing; Male model Renhe male model plate is separated with mother module core and caster, and goods are separated in die cavity.
Along with the raising of scientific and technological level, people are also more strict to the requirement of product appearance quality.More existing injection molds are when die sinking, and moulding is adsorbed on template or the die easily, cause some thin-walled parts such as moulding flexural deformation, particularly notebook computer casing.Because its length or width dimensions are bigger, and wall thickness is thinner, so intensity is relatively poor, when die sinking, the edge of injecting products very easily is adsorbed on the male model plate, causes the moulding distortion, thereby has influenced the quality of product.
Summary of the invention
For solving the deficiency of prior art; The object of the present invention is to provide a kind of liftout attachment of injection mold; And it ejects apart from can change continuously, and this liftout attachment not only can reduce the distortion that moulding produces when die sinking, and can satisfy the needs that difference ejects degree.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
But eject distance continually varying injection mold liftout attachment, it is characterized in that, comprising: wedge block is separately positioned on slide rail, the ejector retainner plate of above-mentioned wedge block both sides; Above-mentioned wedge block slides on slide rail; The front of above-mentioned ejector retainner plate is fixed with thimble, is arranged with the thimble return spring on the above-mentioned thimble; The reverse side of above-mentioned ejector retainner plate is formed with the inclined-plane, and the inclined-plane contacts with wedge block, and slides relatively along wedge block.
But the aforesaid distance continually varying injection mold liftout attachment that ejects is characterized in that above-mentioned wedge block is provided with scale, and above-mentioned scale is corresponding with the distance that thimble ejects.
But the aforesaid distance continually varying injection mold liftout attachment that ejects is characterized in that, number >=2 of thimble in the above-mentioned thimble return spring.
But the aforesaid distance continually varying injection mold liftout attachment that ejects is characterized in that, also comprises: the slide block return spring, with the vertically disposed fixed head of above-mentioned slide rail; The two ends of above-mentioned slide block return spring are fixedly connected on respectively on the tip and fixed head of wedge block.
Usefulness of the present invention is: the top board with thimble slides on wedge block, and the distance that thimble ejects product can change continuously, has satisfied the different needs that eject degree; Be arranged with the thimble return spring on the thimble, help the smooth return of ejector retainner plate, and directly sheathedly saved unnecessary part, be convenient to install; The tip of wedge block is connected with the slide block return spring, can assist the wedge block return.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of liftout attachment of the present invention;
The implication of Reference numeral among the figure:
The 1-wedge block, 2-slide rail, 3-ejector retainner plate, 4-thimble, 5-thimble return spring, 6-slide block return spring, 7-fixed head, 8-inclined-plane.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
With reference to Fig. 1, but the distance continually varying injection mold liftout attachment that ejects of the present invention comprises: wedge block 1 is separately positioned on the slide rail 2 and ejector retainner plate 3 of wedge block 1 both sides.Ejector retainner plate 3 is divided into positive and negative two sides; The front is fixed with thimble 4; For making product eject back center plate 3 return smoothly, be arranged with thimble return spring 5 on the thimble 4, thimble 4 can be all, also can partly be set in the thimble return spring 5; As a kind of preferred, number >=2 of thimbles 4 in the thimble return spring 5; The reverse side of ejector retainner plate 3 is against on the wedge block 1, takes place to slide relatively with wedge block 1, for making ejector retainner plate 3 smoothly, slide stably; Can suitably increase the contact area between ejector retainner plate 3 and the wedge block 1; Concrete, ejector retainner plate 3 is cut an inclined-plane 8 parallel with the inclined-plane of wedge block 1 along self thickness direction, and the while can also be set up lead (not shown) on ejector retainner plate 3; The corresponding gathering sill that cooperates with lead of on the male model plate, offering is in order to moving of guiding ejector retainner plate 3.
As a kind of preferred scheme, wedge block 1 is provided with scale, and this scale is corresponding with the distance that thimble 4 ejects.For different dies or product, the distance that need eject can be different, can more convenient operator use through the scale that is arranged on the wedge block 1.
As a kind of preferred scheme, liftout attachment of the present invention also comprises: slide block return spring 6 and fixed head 7.Fixed head 7 and slide rail 2 vertical settings are used for fixing an end of slide block return spring 6, and the other end of slide block return spring 6 is fixedly connected on the tip of wedge block 1.Slide block return spring 6 can be assisted wedge block 1 return.
With reference to Fig. 1, the course of work of the present invention is: wedge block 1 slides to the right on slide rail 2, and ejector retainner plate 3 relative wedge blocks 1 slide then; Be specially and move up; Thimble 4 moves up thereupon product is ejected mould, and wedge block 1 slides left and withdraws from then, under the elastic force effect of thimble return spring 5 and under the gravity effect; Ejector retainner plate 3 drives thimble 4 and falls back to original position, and the whole process that ejects finishes.
Need to prove that liftout attachment of the present invention is not limited to the described horizontal positioned of Fig. 1, it can also be vertical placement, is specially slide rail 2 and is vertical placement, and ejector retainner plate 3 along continuous straight runs move.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
