Abstract
The utility model relates to an elastic pull rod nut of a plastic jetting-moulding machine, which is used for improving the performance of the pull rod nut. The elastic pull rod nut of the plastic jetting-moulding machine is a complex of a cone and a cylinder; a screw is formed at the center of the cone; a circular hole is formed at the center of the cylinder; the rounding transition is adopted between the cone and the cylinder; and a circular hole for fastening is formed on the outer end surface. The function of the elastic pull rod nut is that the pull rod of the plastic jetting-moulding machine and the elastic pull rod nut of the plastic jetting-moulding machine are in completive elasticity fit, therefore, the stress condition of the pull rod of the plastic jetting-moulding machine is improved; the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to a kind of injection machine elastic draw bar nut.Be used to improve the performance of pull-rod nut.
Background technique
What use on the general injection machine pull bar is stiff nut, because of pull bar stressed big, and the load effect that frequently is hit, the long-term use damage that fractures easily brings many troubles to the user, the similar patented technology of development is that a section with nut changes the elastic region into, and another section still is an inelastic range, and wall is thicker, i.e. the only flexible effect in the part area of nut, therefore it the mechanical property of improving pull bar is only play a part certain, but unresolved problem.
Summary of the invention
At the deficiency of existing product, the utility model provides a kind of injection machine elastic draw bar nut, and pull bar is fastened in the perfect elasticity zone of this nut, fundamentally improves the mechanical property of pull bar, prolongs its working life.
The utility model be achieved in that injection machine elastic draw bar nut be in the middle of for the cone of screw with middlely be the cylindrical assemblying body of circular hole, rounding off between cone and the cylindrical body is provided with the circular hole of fastening usefulness on the exterior edge face.The height H of nut=1～1.8M (diameter of thread), the end diameter d1=1.2～1.6M of cone, tapering are 1: 1.4～2.1, cylindrical outer diameter D=1.5～2.5M, cylindrical aperture d2=1.1～1.5M, cylindrical height h=0.2～0.5M.
Effect of the present utility model is that injection machine pull bar and injection machine elastic draw bar nut are full resilient engagement, thereby has improved the force-bearing situation of injection machine pull bar effectively, and simple for structure, with low cost.
Description of drawings
Fig. 1 is the sectional view of the utility model injection machine elastic draw bar nut.
Fig. 2 is the user mode figure of the utility model injection machine elastic draw bar nut.
Among the figure: 1. injection machine elastic draw bar nut, 2. a plate, 3. pull bar.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: injection machine elastic draw bar nut 1 is formed by metal material processing, during use in a plate 2 and pull bar 3, injection machine elastic draw bar nut 1 cooperation place, open a groove, the slotted eye of the excessive plate 2 of pull bar 3 string then, be fastened on the pull bar 3 by injection machine elastic draw bar nut.
