Abstract
The utility model discloses a high-precision positioning device for a die. A cavity of the die consists of a front die core (1), a sliding block insert (2) and a rear die core (4); the sliding block insert (2) is connected with a lower die part in a positioning manner; and the high-precision positioning device is arranged between the front die core (1) and the sliding block insert (2). The high-precision positioning device is characterized by consisting of a positioning convex block on the front die core (1) and a positioning concave groove in the sliding block insert (2); and the positioning convex block is connected with the positioning concave groove in a positioning manner. When plastic is injected into a product cavity, in spite of outwards tension of pressure, the positioning convex block is clamped into the positioning concave groove, so that the sliding block insert can be prevented from moving, and the product cavity cannot be deformed.
Description
Technical field
The utility model relates to the high-precision positioner of mould of plastics, refers more particularly to the high-precision positioner of the mould of slide block class.
Background technology
For producing some like phone housing, one type of mould of plastics that has curved edges along bar of housing of TV set, its crooked edge bar generally be the back die of preceding die, back mould through front mould and be clipped in front mould with the back mould between the common product die cavity of forming of slide block mold insert finalize the design and produce.The shape of product is by the shape decision of product die cavity, and still, when plastics were injected into the product die cavity, because there is outside tension force in injection pressure, the slide block that can cause constituting the product die cavity was retreated, in case slide block is retreated, just causes the product mold cavity deformation.Even slide block has only slight retreating, for this product that has curved edges along bar, also have the generation of appearance section difference, influence the attractive in appearance and performance of product greatly.In order to overcome this defective, present existing technology is to realize through increasing complicated high precision zero portion article spare.
The utility model content
The purpose of the utility model is to provide a kind of high-precision positioner of mould, under the tension force of injection pressure, solves the problem of mould slide block displacement, has curved edges produces appearance section difference along the product of bar problem thereby solved.
In order to address the above problem, the utility model is not adopting under the prerequisite that increases complicated high precision zero portion article spare, in the prior art around the front mould of product die cavity and be clipped in front mould and afterwards the structure of the slide block mold insert between the mould make improvement, technical scheme is following:
The die cavity of this mould is made up of preceding die, slide block mold insert and back die; Slide block mold insert and part of the lower die are located by connecting; Said high-precision positioner is arranged between preceding die and the slide block mold insert; It is characterized in that: said high-precision positioner is made up of the detent on locating convex block on the preceding die and the slide block mold insert, and described locating convex block and detent are located by connecting.
Locating convex block is cuboid or truncated rectangular pyramids, and when locating convex block was cuboid, the die joint of locating convex block was provided with fillet; When locating convex block was truncated rectangular pyramids, the terrace with edge face was the locating convex block lower surface; The groove bottom degree of depth of detent is greater than the height of locating convex block.
The utility model increases by place's locating convex block on the preceding die of front mould, at the corresponding site excavation one location groove of the slide block mold insert that is connected with locating convex block, this detent is big or small, shape is lucky and locating convex block is adaptive; For easy to process; Reduce the required precision of bottom portion of groove, the degree of depth adopts the empty avoiding form, and locating convex block snaps in detent; Can stop the slide block mold insert to produce displacement, guarantee that the product die cavity is indeformable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation
Fig. 1, be the structural representation of this practical embodiment 1 hi-Fix mechanism.
Fig. 2, be the matched moulds view of this practical embodiment 1 mould.
Among the figure: preceding die 1, slide block mold insert 2, Angle Pin 3, back die 4, latch segment 5, wear-resistant block 6, take-up housing 7, spring 8.
The specific embodiment
Embodiment 1:
Fig. 1 shows the utility model--an embodiment of the high-precision positioner of-mould; The product die cavity of mould is to be used to process have the product of curved edges along bar, the shape of this product die cavity and border by preceding die 1, slide block mold insert 2, back die 4 around forming.Increase by place's locating convex block on the preceding die 1, locating convex block adopts truncated rectangular pyramids, and the side angle of truncated rectangular pyramids is at the 8-15 degree.Corresponding site excavation one location groove at the slide block mold insert 2 that is connected with locating convex block.Belong to when locating convex block and groove setting movement and be slidingly connected, belong to fixed connection in the time of fixedly, can not move arbitrarily in the horizontal direction between making it, fit tolerance is 0.01.
The degree of depth adopts the empty avoiding form simultaneously, and locating convex block snaps in detent, can stop slide block mold insert 2 to produce displacement, guarantees that the product die cavity is indeformable.Angle Pin 3 is to be slidingly connected with take-up housing 7 among Fig. 1, and when the mould die sinking, Angle Pin 3 can drive take-up housing 7 and move; Latch segment 5 is to be fixedly connected with wear-resistant block 6, has had wear-resistant block 6 can increase the life-span of latch segment 5, because wear-resistant block 6 has been arranged, latch segment 5 need not directly contact with take-up housing 7; Take-up housing 7 is to be slidingly connected with wear-resistant block 6, and when the mould die sinking, take-up housing 7 is in contact with one another with wear-resistant block 6, and the long-time like this wear-resistant block 6 that goes down may be worn, but wear-resistant block 6 has protected other part impaired; Spring 8 is to be slidingly connected with take-up housing 7, and when the mould die sinking, the elastic force of spring 8 can make take-up housing 7 move.
Claims (2)
1. the high-precision positioner of a mould; The die cavity of this mould is made up of preceding die (1), slide block mold insert (2) and back die (4); Slide block mold insert (2) is located by connecting with the part of the lower die, and said high-precision positioner is arranged between preceding die (1) and the slide block mold insert (2), it is characterized in that: said high-precision positioner is by the locating convex block on the preceding die (1); Form with the detent on the slide block mold insert (2), described locating convex block and detent are located by connecting.
2. the high-precision positioner of mould as claimed in claim 1, it is characterized in that: locating convex block is cuboid or truncated rectangular pyramids, when locating convex block was cuboid, the die joint of locating convex block was provided with fillet; When locating convex block was truncated rectangular pyramids, the terrace with edge face was the locating convex block lower surface; The groove bottom degree of depth of detent is greater than the height of locating convex block.
