Abstract
The utility model discloses a durable section mould utensil thimble, including base, thimble pole, spring, abutment sleeve, the constant head tank, thimble pole bottom install with the base on, spring one end links to each other with the base, and one end links to each other with the sleeve, the thimble pole has three constant head tanks, abutment sleeve installs and holds at the thimble peak of the staff, thimble pole and abutment sleeve insert in the guiding hole, the guiding hole is close to thimble direction end and is provided with the spacing ring. Three constant head tanks for each other becoming 120 degrees distributions along thimble pole horizontal circumference direction. The constant head tank is partly for the circle. Abutment sleeve's the corresponding positioning tracks that has is prominent half -cylinder. In this way, the utility model discloses can solve the noise that leads to among the operation process, the while also can reduce the life of the friction between thimble and sleeve, very big extension thimble.
Description
Technical field
This utility model relates to a kind of thimble, is particularly applied in the durable mould thimble on mould.
Background technology
Die ejector pin is that one is arranged in mould installing hole, and at goods after mould completes processing, die ejector pin stretches out from installing hole, the device come from mold ejection by product.Existing die ejector pin by goods from the process of mold ejection, owing to ceaselessly doing reciprocating action, contact frequently with installing hole inner surface cause friction, thus causing the abrasion of thimble；Thus causing that thimble body loosens and produces noise；Also lead to thimble stress displaced central axis simultaneously and thrust need to be increased, even result in overload and destroy puopulsion equipment, simultaneously because the damage of thimble is accelerated in lasting abrasion.
Summary of the invention
Utility model purpose: the purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of low noise, a kind of durable mould thimble of long service life.
Technical scheme: for achieving the above object, this utility model provides one to include base, thimble rod, spring, abutment sleeve, locating slot, described thimble rod bottom be arranged on on base；Described spring one end is connected with base, and one end is connected with sleeve；
Described thimble rod has three locating slots；
Described sleeve is arranged on thimble rod top；
Described thimble rod and sleeve are inserted in pilot hole, and described pilot hole is provided with spacing ring near thimble direction end.
This utility model is by being the designs being mutually 120 degree of distributions along thimble rod horizontal circle circumferential direction at three locating slots, thimble rod is made to be more uniformly stressed by the positioning action of sleeve in progradation, reducing vibrations, thus reducing vibrations friction, extending the service life of thimble rod.
When the part that locating slot described in this utility model is round is to make die ejector pin advance in sleeve, frictional force is minimum, thus reducing the abrasion of thimble rod, increases the service life.
Described sleeve positioning track of the present utility model is the column type of the projection locating slot in order to better mate on thimble rod, reduces friction during thimble rod motion.
Beneficial effect: compared with prior art, this utility model has the advantage that
This utility model is by arranging three locating slots on sleeve, and the spring of sleeve and bottom is connected directly between on thimble rod, is more uniformly stressed so that adding man-hour, reduces friction thimble rod and the friction of pilot hole, extends the service life of thimble rod.
Accompanying drawing explanation
Fig. 1 is the details drawing of thimble structure；
Fig. 2 is the top view on thimble rod top；
In figure: 1 base, 2 springs, 3 sleeves, 4 locating slots, 5 thimble rods, 6 pilot holes, 7 spacing rings.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is all fallen within the application claims limited range by those skilled in the art.
Embodiment:
A kind of die ejector pin one die ejector pin as shown in Figure 1, 2, it is characterised in that: include base 1, thimble rod 5, spring 2, abutment sleeve 3, locating slot 4, described thimble rod 5 bottom be arranged on base on 1；Described spring 2 one end is connected with base 1, and one end is connected with sleeve 3；Described thimble rod has three locating slots；Described sleeve is arranged on thimble rod top；Described thimble rod and sleeve are inserted in pilot hole 6, and described pilot hole is provided with spacing ring 7 near thimble direction end；It is characterized in that described three locating slot is for be mutually 120 degree of distributions along thimble rod 5 horizontal circle circumferential direction；It is characterized in that the part that described locating slot 4 is circle；It is characterized in that the semicircle column type having corresponding positioning track to be projection on described abutment sleeve 5.
The operation principle of the present embodiment is: when thimble is started working, thimble rod 5 is forward motion together with base 1 and sleeve 3, spring 4, when arriving under spring 4 non-deformed state when sleeve on the spacing ring 7 in pilot hole 6, sleeve 3 stop motion, now thimble 5 self continues forward under the restriction of the corresponding positioning track on sleeve 3 of the locating slot 4 on thimble body, thus the goods that jack-up completes；After jack-up goods, thimble is retracted by thimble under the back stretch effect of spring 4, thus completes an actuation cycle.
