Abstract
The utility model provides a notch cuttype reference column which characterized in that: including last locating piece and lower locating piece, go up the step cylinder of locating piece for the area shoulder, down the locating piece be equipped with with step cylinder complex shoulder hole. The utility model provides a notch cuttype reference column, utilizes step cylinder's big or small cylinder to carry out two location, under the condition that does not increase the reference column manufacturing cost and the degree of difficulty, satisfies the location requirement of mould.
Description
Technical field
The invention relates to a kind of stepped positioning column, belongs to technical field of mold.
Background technology
Locating dowel is to make a kind of dieparts of mould work well for the position in plastic mould precisely between locking module and template.Locating dowel is that upper locating piece and concavo-convex combination of lower locating piece configure, and general upper locating piece, for being with shoulder cylindrical, manufacturing simple, can meet mould positioning requirements in the ordinary course of things.But requiring that positioning precision is in particular cases high, even if improve the quality of fit of cylinder and mating holes, be also often difficult to reach required precision.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to provide a kind of stepped positioning column, utilizing the large small column of stepped cylindrical to carry out two location, when not increasing locating dowel manufacturing cost and difficulty, meeting the positioning requirements of mould.
For achieving the above object, the invention is realized by following technological means:
A kind of stepped positioning column, is characterized in that: comprise locating piece and lower locating piece, and described upper locating piece is the stepped cylindrical of band shoulder, and described lower locating piece is provided with the shoulder hole coordinated with stepped cylindrical.
Further:
The material of described upper locating piece and lower locating piece is mould steel.
Described stepped cylindrical and shoulder hole surface adopt sulfurizing process.
Described stepped cylindrical and shoulder hole adopt rounding structure.
The diameter of the big column of described stepped cylindrical is 2 times of small column diameter.
The length of the big column of described stepped cylindrical is 1/2nd of small column length.
The beneficial effect of the invention is: a kind of stepped positioning column that the invention provides, and utilizing the large small column of stepped cylindrical to carry out two location, when not increasing locating dowel manufacturing cost and difficulty, meeting the positioning requirements of mould.
Accompanying drawing explanation
Positioning block structure schematic diagram on Fig. 1, positioning block structure schematic diagram under Fig. 2.
Detailed description of the invention
Below in conjunction with Figure of description, the invention is further described.
As shown in accompanying drawing 1,2, a kind of stepped positioning column, is characterized in that: comprise locating piece and lower locating piece 3, and described upper locating piece is the stepped cylindrical 2 of band shoulder 1, and described lower locating piece is provided with the shoulder hole 4 coordinated with stepped cylindrical 2.Two location, can correct deviations.
Further:
The material of described upper locating piece and lower locating piece 3 is mould steel.
Described stepped cylindrical 2 and shoulder hole 4 surface adopt sulfurizing process.Wear-resisting lubrication.
Described stepped cylindrical 2 and shoulder hole 4 adopt rounding structure.Be convenient to upper and lower locating piece coordinate.
The diameter of the big column of described stepped cylindrical 2 is 2 times of small column diameter.
The length of the big column of described stepped cylindrical 2 is 1/2nd of small column length.
More than show and describe the general principle of the invention, principal character and advantage.The technical staff of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and description; under the prerequisite not departing from the design's spirit and scope; the invention also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the invention is defined by appending claims and equivalent thereof.
