The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Refer to Fig. 1, it is the structural representation of injection mould when matched moulds state with mold cores micro-adjusting mechanism, and this injection mold comprises front mould 10 and the rear mold 20 being oppositely arranged, and front mould 10 inside are provided with TOP-TIP 11.
Please continue to refer to Fig. 1 to Fig. 7, in described front mould 10, be provided with front cavity 12, this front cavity 12 has deep hole; The lower surface of front cavity 12 is fixed with front mould mold insert 30, and particularly, this front mould mold insert 30 has hollow tubular structure, and it is fixed on the bottom face of described front cavity 12 by alignment pin; The bottom opening place of this front mould mold insert 30 forms a host cavity (not indicating in figure), and the relative both sides of inwall of this host cavity are respectively equipped with an interior inclined-plane 31; In described rear mold 20, be provided with core 21, this core 21 is elongated rod shape, and 21 middle parts of core are arranged with core positioning sleeve 40, and the relative both sides of these core positioning sleeve 40 outer surface of cupular part are respectively equipped with the outer inclined-plane 41 paralleling with the interior inclined-plane 31 of front mould mold insert 30; During matched moulds, the top of core 21 is inserted in front cavity 12 through front mould mold insert 30, insert in front mould mold insert 30 at the top of core positioning sleeve 40, the common die cavity (not indicating in figure) that forms of this front cavity 12, core 21, core positioning sleeve 40 and front mould mold insert 30, described TOP-TIP 11 bottoms are provided with the glue feeding opening (not indicating in figure) being connected with this die cavity; Wherein, between the interior inclined-plane 31 of front mould mold insert 30 and the outer inclined-plane 41 of core positioning sleeve 40, form the two adjustment spaces that lay respectively at core 21 relative both sides, two lines of adjusting spaces and described glue feeding opening towards consistent, in each adjustment space, install respectively an adjustment block 51(as shown in Figure 1, Figure 2 and shown in Fig. 7).
When debugging, when penetrating from glue feeding opening, the melten gel of high speed and high pressure can cause powerful impact to elongated rod shape core 21, and on core positioning sleeve 40, the core 21 of part can be offset; In the situation that upper part type core 21 is offset left, can the enlarged in thickness of the adjustment block 51 in core 21 left sides will be positioned at, now, the top of core positioning sleeve 40 is subject to the acting in conjunction of front mould mold insert 30 and left side adjustment block 51 and pushes core 21 to the right, makes part type core 21 obtain a preset side-play amount to the right; After matched moulds, when melten gel impacts elongated rod shape core 21 again, the skew of turning left of upper part type core 21, compensates described preset side-play amount, thereby guarantees that core 21 and die cavity keep concentric, and then the qualification rate of raising shaped article; And this kind solves the mode of core 21 offset problems, only need to change the adjustment block 51 of different-thickness, not needing increases other parts again, is conducive to cost-saving; In like manner, when there is the situation of skew to the right in upper part type core 21, the adjustment block 51 of correspondingly changing right side just can, easy and simple to handle.
Refer to Fig. 1 and Fig. 4, specifically in the present embodiment, described core 21 has the up-thin-low-thick body of rod, and the middle part of the body of rod forms tapered tapering 211 from the bottom to top; The central shaft of described core positioning sleeve 40 is formed for wearing the core via hole 42 of core, this core positioning sleeve 40 is nested in tapering 211 outer surfaces of core 21, the relative both sides of core positioning sleeve 40 outer surface of cupular part are respectively equipped with an accommodating groove, the diapire of each accommodating groove form one described in outer inclined-plane 41; Described adjustment block 51 is taken in and is fixed in this accommodating groove; During matched moulds, the top of this core positioning sleeve 40 is inserted in the host cavity of described front mould mold insert 30, and particularly, the interior inclined-plane 31 of the accommodating groove of core positioning sleeve 40 and front mould mold insert 30 is formed for taking in the extruding space of the described adjustment block 51 of clamping jointly; Preferably, described front mould mold insert 30 is to make by the higher material of hardness, when being installed in front template, this front mould mold insert 30 to carry out pre-hard processing, while guaranteeing mould matched moulds, front mould mold insert 30 can not cause the deformation of front mould mold insert 30 with the mutual extruding of adjustment block 51, thereby, when the thickness of adjustment block 51 is greater than the degree of depth of accommodating groove, thereby the top that can guarantee core positioning sleeve 40 is squeezed and elastic deformation occurs makes core 21 that respective offsets occur.
Refer to Fig. 2 to Fig. 5, further, the bottom of described core 21 is provided with core hanging platform 212, the middle part of described core positioning sleeve 40 is provided with positioning sleeve hanging platform 43, the bottom of described front cavity 12 is provided with die hanging platform 121, these hanging platform structures can play guarantees that core 21, core positioning sleeve 40 and front cavity 12 are arranged on the stability of position in mould, prevents that it from occurring loosening.
In order to prevent that core 21, core positioning sleeve 40 from rotating, and offer the flat position 123 of anti-rotation at the sidewall of described core hanging platform 212, positioning sleeve hanging platform 43, at the sidewall of core hanging platform 212 and positioning sleeve hanging platform 43, cut and establish a plane.
Refer to Fig. 1, Fig. 2 and Fig. 3, preferably, described positioning sleeve hanging platform 43 is formed at the relative both sides at core positioning sleeve 40 middle parts, and wherein a side positioning sleeve hanging platform 43 is fixed in rear mold 20 by a briquetting 61, can further strengthen the installation stability of this core positioning sleeve 40.
Refer to Fig. 2, in addition, the center line of described core 21 be provided with fortune water hole 213, this fortune water hole 213 lowers the temperature to core 21 for injecting cooling water, be conducive to prevent core 21 overheated and generation deformation.
As mentioned above, a kind of mold cores micro-adjusting mechanism of the utility model is when mould matched moulds, rely on the mold clamping force extruding core positioning sleeve 40 of injection machine, core positioning sleeve 40 pushes core 21 again, by changing the thickness of core 21 both sides adjustment blocks 51, make core 21 be extruded the angle that the angle of inclination and melten gel impact core 21 skews and offset, finally make core 21 and die cavity keep concentric, thus raising product percent of pass.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
