Abstract
The utility model provides a spring limit structure for a mould. The spring limit structure is simple in structure, can adapt to requirements of large-scale manufacturing of products and comprises an upper fixed plate, a stripper plate, a plate A, a front module kernel, a back module kernel, a plate B, a puller bushing and a flow channel, wherein the upper fixed plate is fastened by the upper end of the puller bushing; the lower end of the puller bushing is communicated with a mold cavity which is formed by the front module kernel and the back module kernel through the flow channel; the puller bushing penetrates the stripper plate; the flow channel is positioned in the plate A and the front module kernel; and a resin shutter is connected between the plate A and the plate B. Besides, the limit structure is characterized in that: a spring installation cavity is formed on the plate A; a spring, a spring housing and a stop screw are arranged in the spring installation cavity; an inner hole which has a shape like a reversed Chinese character 'tu' is formed in the spring housing; the spring housing comprises an upper end and a lower end; the diameter of the upper end of the spring housing is greater than that of the lower part of the spring housing; the upper end of the stop screw is tightly attached to the lower end surface of the stripper plate; and the lower end of the stop screw is pressed against the upper end surface of the plate B.
Description
Technical field
The utility model relates to the technical field of structures of mould, is specially a kind of spring position limiting structure of mould.
Background technology
In the application of mould design medi-spring very extensively, in the time of the tool die sinking, the elastic force that separates needs dependence spring of template and template.The location of self also was a problem when but spring flicked; If spring does not have spacing fixing, self also can eject because of the effect of elastic force when ejecting, and does not so just have the effect that spring should play; So generally can use spring glue; But spring glue is not durable, non-refractory, and the incompatibility mould is produced product demand in enormous quantities.
Summary of the invention
To the problems referred to above, the utility model provides a kind of spring position limiting structure of mould, and it is simple in structure and can adapt to the production in enormous quantities product demand.
A kind of spring position limiting structure of mould; Its technical scheme is such: it comprises upper mounted plate, stripper plate, A plate, preceding die, back die, B plate, mouth of a river cover, runner; The fastening said upper mounted plate in upper end of said mouth of a river cover, the lower end of said mouth of a river cover is communicated with said preceding die, the formed die cavity of back die through said runner, and said mouth of a river cover runs through said stripper plate; Said runner is positioned at said A plate, preceding die; Be connected with the resin shutter between said A plate, B plate, it is characterized in that: said A plate has spring cavity is installed, and said spring is installed in the cavity spring, spring housing, limit screw are installed; Said spring housing has the convex-down endoporus; Said spring housing comprises upper end, bottom, and the upper end diameter of said spring housing is greater than its underpart, and the upper surface that the lower surface of said stripper plate, lower end are mounted on said B plate is close in the upper end of said limit screw; The periphery of said limit screw is set with said spring housing; Lower surface, the end part of the die joint of the convex-down endoporus of said spring housing and said limit screw leaves the gap, and said spring housing is loaded on the bottom of said spring housing, and the two ends of said spring are mounted on the upper end bottom surface of said spring housing, the lower surface that spring is installed cavity respectively.
After adopting the said structure of the utility model, A plate, B plate are held motionlessly during die sinking by the resin shutter, and the A plate relies on stripper plate that spring housing is first to be separated; Spring promotes spring housing and ejects after the clearance distance; Rely on limit screw that spring housing is spacing, it is high temperature resistant that this structure is compared spring glue, and range of application is more extensive; The reliability durability is also higher, and it is simple in structure and can adapt to the production in enormous quantities product demand.
Description of drawings
Fig. 1 is a front view structural representation under the matched moulds state of the utility model.
The specific embodiment
See Fig. 1, it comprises upper mounted plate 1, stripper plate 2, A plate 3, preceding die 4, back die 5, B plate 6, mouth of a river cover 7, runner 8, the fastening upper mounted plate 1 in upper end of mouth of a river cover 7; Die 4, back die 5 formed die cavities 9 before the lower end of mouth of a river cover 7 is communicated with through runner 8; Mouth of a river cover 7 runs through stripper plate 2, and runner 8 is positioned at A plate 3, preceding die 4, is connected with resin shutter 10 between A plate, B plate; A plate 3 has spring cavity 11 is installed; Spring is installed in the cavity 11 spring 12, spring housing 13, limit screw 14 is installed, and spring housing 13 has convex-down endoporus 15, and spring housing 13 comprises upper end 16, bottom 17; Upper end 16 diameters of spring housing 13 are greater than bottom 17 diameters; Lower surface, the lower end that stripper plate 2 is close in the upper end of limit screw 14 is mounted on the upper surface of B plate 6, and the periphery of limit screw 14 is set with spring housing 13, and the die joint 18 of the convex-down endoporus 15 of spring housing 13 leaves gap 19 with lower surface, the end part of limit screw 14; Spring 12 is set in the bottom 17 of spring housing 13, and the two ends of spring 12 are mounted on upper end 16 bottom surfaces of spring housing 13, the lower surface that spring is installed cavity 11 respectively.
