Abstract
The utility model provides a mould structure capable of realizing automatic falling of a product through floating sliding block core-pulling which is simple in structure, low in cost and attractive in appearance without centre trace. The mould structure comprises a mould, a hydraulic cylinder and a sliding block mechanism, wherein the hydraulic cylinder drives the sliding block mechanism to horizontally move so as to enable the product to be separated from a cavity, and a baffle plate is arranged to limit the movement of the sliding block mechanism. The mould structure is characterized in that the hydraulic cylinder and the sliding block mechanism are integrally pushed by an ejection mechanism to move up and down, the ejection mechanism is connected with the sliding block mechanism through a sliding block ejection rod, and a limiting block for limiting the displacement of the sliding block mechanism is arranged in a displacement range of the sliding block mechanism.
Description
Technical field
The present invention relates to the plastic products mould applications.
Background technology
Manufacture for this type of circle plasthetics is all to adopt hydraulic jack to loose core at present, and thimble ejects goods, thereby product surface leaves thimble, trace affects products appearance.And Core-pulling distance is from oversize, the production of articles cycle lengthens, and mould bases increases, and has also increased the Mold Making cost.
Summary of the invention
The invention provides a kind of simple in structure, cost is low, do not have the floating slider thimble vestige, the outward appearance grace to loose core realizes the mould of goods Automatic-falling.
For solving the problems of the technologies described above, the technical solution used in the present invention is: provide a kind of floating slider to loose core and realize goods Automatic-falling mould, comprise mould A plate and B plate, hydraulic jack and slide block mechanism, hydraulic jack drive slide block mechanism moves horizontally and makes goods break away from die cavity, being provided with baffle plate restriction goods moves, described hydraulic jack and slide block mechanism integral body are ejected mechanism urges and move up and down, ejecting mechanism, by slide block push rod connection sliding block mechanism, is provided with the limited block that limits its displacement between the slide block mechanism displacement field.Mould is after die sinking, the slide block push rod ejects whole slide block mechanism after the L distance, hydraulic jack starts to loose core, goods arrive baffle position to be stopped, under baffle effect, goods start to separate with the slide block core, after the line position seat arrives stroke, goods and slide block core are fully loosening, and goods are realized Automatic-falling.
Further, described slide block mechanism comprises take-up housing, and take-up housing is being fixedly connected with the slide block core, and outside the slide block core, cover is goods then.
Further, outside the slide block push rod, be socketed accurate guide pin bushing; And slide block mechanism inside is goed deep on slide block push rod top, thereby guaranteed that slide block mechanism leads accurately in location free procedure, reliable in action.
Further, inner 6 millimeters of slide block mechanism is goed deep on slide block push rod top.
Further, stud with the brass guide pin bushing matched with slide block core shape on baffle plate,, reduce the wearing and tearing of slide block core, increase the slide block core and make to do the life-span.
Further, between baffle plate and B plate, keep gradient, make the smooth return of slide block mechanism floating slider, realize precise positioning.
Further, keeping gradient between baffle plate and B plate is 3～5 degree.
Further, described slide block push rod has a plurality of, keeps balance.
Compared with prior art, beneficial effect is: the present invention does not have the thimble vestige, can effectively make products appearance meet the requirement of using, and meets the application of the occasion that appearance requirement is higher.
The accompanying drawing explanation
Fig. 1 is the die sinking schematic diagram;
Fig. 2 is vertical spacing schematic diagram;
Fig. 3 is the level schematic diagram of loosing core;
Wherein: 1, limited block; 2, brass bushing; 3, the slide block core; 4, baffle plate; 5, hydraulic jack; 6, the slide block push rod; 7, die cavity; 8, goods; 9, B plate; 10, A plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The present invention includes mould A plate and B plate, hydraulic jack 5 and slide block mechanism, hydraulic jack 5 drive slide block mechanisms move horizontally and make goods 8 break away from die cavities 7, being provided with baffle plate 4 restriction goods 8 moves, described hydraulic jack 5 and slide block mechanism integral body are ejected mechanism urges and move up and down, ejecting mechanism, by slide block push rod 6 connection sliding block mechanisms, is provided with the limited block 1 of restriction slide block push rod 6 displacements between the slide block mechanism displacement field.Slide block mechanism comprises take-up housing 11, and take-up housing 11 is being fixedly connected with slide block core 3, and slide block core 3 outer surface covers are goods 8 then.Outside slide block push rod 6, be socketed accurate guide pin bushing; And slide block mechanism inside is goed deep on slide block push rod 6 tops.Stud with the brass guide pin bushing matched with slide block core 3 shapes on baffle plate 4.Keep gradient between baffle plate 4 and B plate 9.
From accompanying drawing 1 to accompanying drawing 3, after mould A plate 10 completes die sinking with B plate 9, the ejecting mechanism setting in motion of injection machine, slide block mechanism and hydraulic jack 5 start to move upward under the ejecting of 4 slide block push rods 6; 1 position-limiting action of limited block after stroke arrives distance L, the ejecting mechanism stop motion, now goods 8 and slide block mechanism have completed the disengaging die cavity.Goods 8 are also stayed slide block core 3 outer surfaces, hydraulic jack 5 starts to loose core, goods arrive baffle position to be stopped, hydraulic jack continues motion, goods start to extract out from slide block core 3 under the promotion of baffle plate 4, after the line position seat arrives the S stroke, goods and slide block core are fully loosening, thereby realize that goods are without thimble trace Automatic-falling.
The foregoing is only an example of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in protection scope of the present invention.
