Abstract
The utility model relates to a be used for ejecting fan-shaped ejector pin of die casting mould, the ejector pin body includes shaping portion, rib and table portion, the shaping portion cross-section is fan-shaped, and two arc surfaces of this shaping portion lower extreme outwards off-set form the rib, rib lower extreme radial outside off-set forms table portion, the utility model discloses a through reducing fan-shaped ejector pin ejecting part effective length, increase its lower extreme thickness on fan-shaped ejector pin basis to increase its intensity, reduce because of the production of fan-shaped ejector pin itself more long and thin flexible and cracked problem.
Description
Technical Field
The utility model relates to an ejecting field of mould especially relates to a be used for ejecting fan-shaped ejector pin of die mould.
Background
Ejector rods in the die are common ejection components, the cross sections of the ejector rods mainly comprise a round shape and a square shape, the ejector rods have good strength, fan-shaped ejector rods are required to be arranged at ejection positions of some dies, the space is often small, the requirement on processing is high, the existing fan-shaped ejector rods are slender and easy to bend and break, and therefore the stability of die production is affected and the production efficiency is reduced.
Disclosure of Invention
The utility model discloses a reduce fan-shaped ejector pin ejecting part effective length, increase its lower extreme thickness on fan-shaped ejector pin basis to increase its intensity, reduce because of the more long and thin production of easily bending and cracked problem of fan-shaped ejector pin itself.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a fan-shaped ejector pin for die casting die is ejecting, the ejector pin body includes shaping portion, rib and table portion, shaping portion cross-section is fan-shaped, and two arc surfaces of this shaping portion lower extreme outwards offset form the rib, rib lower extreme radially outwards offset forms table portion.
Further, the forming part gradually changes to the reinforcing part to form a transition part.
Further, the transition part is a smooth transition inclined plane, and the angle of the inclined plane ranges from 15 degrees to 25 degrees.
Further, the offset distance of the reinforcing part relative to the forming part is 2 mm.
Has the advantages that: the utility model relates to a be used for ejecting fan-shaped ejector pin of die casting mould, on current basis, do not change fan-shaped ejector pin's ejecting partial shape, increase fan-shaped ejector pin lower extreme thickness to increase its intensity, reduce because of the production of fan-shaped ejector pin itself more long and thin flexible and cracked problem, thereby avoid should fan-shaped ejector pin influence the stability of mould production and the efficiency that reduces production.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a cross-sectional view of the present invention;
fig. 3 is a cross-sectional view of the present invention.
The figure is as follows: 1. a mandril body; 2. a molding section; 3. a transition section; 4. a reinforcing portion; 5. a hanging table part.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-3, the embodiment of the present invention relates to a fan-shaped ejector rod for die casting mold ejection, the ejector rod body 1 includes a forming portion 2, a reinforcing portion 4 and a hanging portion 5, the cross section of the forming portion 2 is fan-shaped, two arc surfaces of the lower end of the forming portion 2 are outwardly biased to form the reinforcing portion 4, and the lower end of the reinforcing portion 4 is radially outwardly biased to form the hanging portion 5.
In order to prevent a sharp angle between the forming part 2 and the reinforcing part 4 of the fan-shaped ejector rod and realize smooth transition, the phenomenon that the connecting sharp point is easy to break due to stress concentration is avoided, and the forming part 2 is gradually changed into the reinforcing part 4 to form a transition part 3.
In order to prevent the fan-shaped ejector pin from interfering with other places and to be used normally, the transition part 3 is a smooth transition inclined plane, and the angle of the inclined plane ranges from 15 degrees to 25 degrees.
In order to provide a certain reinforcement of the reinforcement 4 against breakage and bending without affecting its original use, the offset distance of the reinforcement 4 with respect to the forming section 2 is 2 mm.
As the utility model discloses a manufacture process: the ejector rod body 1 is formed by processing a plurality of steps on a circular pipe material to form the reinforcing part 4 and the hanging table part 5, so that the strength of the ejector rod body is improved, and the ejector rod body is cut according to the required width through wire cutting processing.
The utility model discloses an on current basis, do not change fan-shaped ejector pin's ejecting partial shape, increase fan-shaped ejector pin lower extreme thickness to increase its intensity, reduce because of the production of fan-shaped ejector pin itself more long and thin flexible and cracked problem, thereby avoid should fan-shaped ejector pin influence the stability of mould production and the efficiency of reduction in production, and its relative and preceding mechanism is simpler, the utilization ratio of material also improves greatly.
