Abstract
The invention relates to a mold ejector pin. The mold ejector pin comprises a first ejector pin rod and a second ejector pin rod. The diameter of the second ejector pin rod is greater than that of the first ejector pin rod. The first ejector pin rod is connected to the second ejector pin rod by an elastic element. An outer surface of the second ejector pin rod is provided with a composite layer. The composite layer is arranged on the second ejector pin rod and contains emery and contains silicon carbide so that the mold ejector pin has good wear resistance. Through utilization of the elastic element, buffer can be effectively reduced and a service life is prolonged.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of die ejector pin.
Background technology
Die ejector pin is the goods for the moulding of ejection die, traditional die ejector pin is by the cylindrical, top shank, consist of with the cylindrical thimble countersunk head of cylindrical, top shank one, this cylindrical thimble countersunk head is positioned at an end of cylindrical, top shank, and cylindrical thimble is the cylinder that an external diameter equates, the die ejector pin of this structure is installed in the die ejector pin installing hole in the mould, when needs eject moulded products, the thimble rod of die ejector pin stretches out in installing hole, and moulded products is ejected.Therefore, there is following defective in the die ejector pin of this structure, and whole thimble rod contacts with the installing hole inner surface, when thimble rod moves back and forth, rub with the installing hole inner surface, thereby cause thimble rod outer surface mill flower, thimble rod will produce large impact simultaneously, easily damage.
Summary of the invention
The objective of the invention is provides a kind of die ejector pin in order to overcome the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of die ejector pin comprises the first thimble rod and the second thimble rod, connects by elastic component between described the first thimble rod and the second thimble rod, and the outer surface of described the second thimble rod is provided with composite bed.
Further, the diameter of described the second thimble rod is greater than the diameter of the first thimble rod.
Further, described elastic component is round table-like.
Further, the large end of described elastic component is connected with the second thimble rod, and its small end is connected with the first thimble rod.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arranging composite bed at the second thimble rod, and composite bed includes diamond dust, and wearability is good, and elastic component is set simultaneously, can effectively reduce buffering, improves its service life.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1, Fig. 1 is structural representation of the present invention.
Described a kind of die ejector pin comprises the first thimble rod 1 and the second thimble rod 2, and the diameter of described the second thimble rod 2 is greater than the diameter of the first thimble rod 1,
Connect by elastic component 3 between described the first thimble rod 1 and the second thimble rod 2, effectively reduce buffering, improve its service life, the outer surface of described the second thimble rod 2 is provided with the composite bed (not shown), the thickness of composite bed is 1mm, and composite bed includes diamond dust, improves its wear-resisting effect.
Described elastic component 3 is round table-like, and the large end of described elastic component 3 is connected with the second thimble rod 2, and its small end is connected with the first thimble rod 1.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
