Description
Technical field
The utility model relates to technical field of mold, particularly relates to a kind of Novel mandril.
Background technology
Mould be in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.
Need to use push rod in mould is produced, current push rod lacks spring, when ejecting product, easily make product be bonded on push rod, difficult drop-off, cause the reduction of production efficiency, therefore need to provide a kind of push rod with spring, improve it and release efficiency.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of Novel mandril, and this push rod is with spring.
The utility model is achieved through the following technical solutions:
A kind of Novel mandril, comprise push rod body, the centre position, upper end of described push rod body starts fluted in the axial direction downwards, in groove, be provided with spring, and the two ends, bottom of described spring are arranged on the bottom of groove by voussoir, voussoir is provided with screw.
As optimal technical scheme of the present utility model, described screw is complete thread screw, and the upper surface of screw offers cross recess.
As optimal technical scheme of the present utility model, described screw is sunk screw.
As optimal technical scheme of the present utility model, described spring is volute spring.
As optimal technical scheme of the present utility model, described groove is cylinder shape groove.
Compared with prior art, the beneficial effects of the utility model are: the utility model is provided with spring by the upper end at push rod, and are fixed in a groove by spring by voussoir, spring not easily rocks, when ejecting product, product can not be bonded in the upper end of push rod, improves release efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-push rod body; 2-groove; 3-spring; 4-voussoir; 5-screw.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of Novel mandril, comprise push rod body 1, the centre position, upper end of described push rod body 1 starts fluted 2 downwards in the axial direction, spring 3 is installed in groove 2, the two ends, bottom of described spring 3 are arranged on the bottom of groove 2 by voussoir 4, voussoir 4 is provided with screw 5, and described screw 5 is complete thread screw, the upper surface of screw 5 offers cross recess, and described screw 5 is sunk screw.Described groove 2 is cylinder shape groove, and described spring 3 is volute spring, improves and releases stability.
