Abstract
The invention relates to an improved mold ejector pin structure. The improved mold ejector pin structure comprises an ejector pin body. An upper surface of the ejector pin body is provided with multiple grooves. Elastic elements are arranged in the grooves. A wear-resistant electrostatic layer is uniformly coated on the upper surface of the ejector pin body. The improved mold ejector pin structure has good buffer and anti-skid effects, improves an ejector pin service life and can effectively eliminate electrostatic phenomenon.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of modified form ejector pin structure of die.
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.
The end face of thimble of the prior art and moulded products contact position easily produce static, remain to be eliminated, and easily produce impact phenomenon, reduce the service life of thimble.
Summary of the invention
The objective of the invention is provides a kind of modified form ejector pin structure of die in order to overcome the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of modified form ejector pin structure of die comprises the thimble body, and described thimble body upper surface is provided with a plurality of grooves, is provided with elastic component in the described groove, and the upper surface at the thimble body evenly is coated with wear-resisting electrostatic layer simultaneously.
Further, the quantity of described groove is four.
Further, the cross section of described groove is trapezoidal.
Further, the thickness of described wear-resisting electrostatic layer is 0.5-1mm.
Compared with prior art, the invention has the beneficial effects as follows: buffering of the present invention and good antiskid effect, in the service life of improving thimble, can effectively eliminate electrostatic phenomenon simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention.
