Abstract
The utility model provides a two location reference column which characterized in that: including last locating piece and lower locating piece, the locating piece comprises shoulder, the location cylinder that lies in the shoulder -mounted, the location frustum that lies in on the cylinder of location down, the diameter of location cylinder is the same with the main aspects diameter of location frustum, it is equipped with and fixes a position the cylinder and fix a position the frustum complex and be connected integrative cylinder hole and conical bore to go up the locating piece. The utility model provides a two location reference column, adoption cylinder and the form that the frustum combined together through cylinder and frustum implementation secondary location, under the condition that does not improve cylinder and frustum manufacturing accuracy, satisfy the die positioning required precision.
Description
Technical field
The invention relates to a kind of double location locating dowel, belongs to technical field of mold.
Background technology
Locating dowel be in plastic mould precisely position between locking module and template so that a kind of dieparts of mould work well.Locating dowel is combination concavo-convex with the lower locating piece configuration of upper locating piece, and general upper locating piece is band shoulder cylinder, is simple to manufacture, can meet mould positioning requirements in the ordinary course of things.But requiring that positioning precision is high in particular cases, even if improving the quality of fit of cylinder and mating holes, also tending to be difficult to reach required precision.
Summary of the invention
For the deficiencies in the prior art, the purpose of the invention is to provide a kind of double location locating dowel, uses the form that cylinder combines with frustum, carries out secondary by cylinder and frustum and position, under conditions of not improving cylinder and the frustum accuracy of manufacture, meet mould positioning accuracy request.
For achieving the above object, the invention is realized by techniques below means:
A kind of double location locating dowel, it is characterized in that: include locating piece and lower locating piece, described lower locating piece is made up of the positioning cylinder takeed on, be positioned on shoulder, the location frustum that is positioned on positioning cylinder, the diameter of described positioning cylinder is identical with the outside diameter of location frustum, and described upper locating piece is provided with the cylindrical hole being integrally connected and conical bore coordinated with positioning cylinder and location frustum.
Further:
The height of described positioning cylinder is 2 times of location frustum height.
The material of described upper locating piece and lower locating piece is mould steel.
Described positioning cylinder, location frustum, cylindrical hole and conical bore surface use sulfurizing to process.
Described cylindrical hole bottom uses rounding structure.
Described mould steel model is SCM415.
The invention provides the benefit that: a kind of double location locating dowel that the invention provides, use the form that cylinder combines with frustum, carry out secondary by cylinder and frustum to position, under conditions of not improving cylinder and the frustum accuracy of manufacture, meet mould positioning accuracy request.
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 double location locating dowel, it is characterized in that: include 1 piece, location and lower locating piece 4, positioning cylinder 6, the location frustum 5 that is positioned on positioning cylinder 6 that described lower locating piece 4 by shoulder 7, is positioned on shoulder 7 form, the diameter of described positioning cylinder 6 is identical with the outside diameter of location frustum 5, and described upper locating piece 1 is provided with the cylindrical hole 2 being integrally connected and conical bore 3 coordinated with positioning cylinder 6 and location frustum 5.
Further:
The height of described positioning cylinder 6 is 2 times of location frustum 5 height.
The material of described upper locating piece 1 and lower locating piece 4 is mould steel.
Described positioning cylinder 6, location frustum 5, cylindrical hole 2 and conical bore 3 surface use sulfurizing to process.Wear-resisting lubrication.
Described cylindrical hole 2 bottom uses rounding structure.It is easy to import and eliminate stress concentrate.
Described mould steel model is SCM415.
The general principle of the invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the design is not restricted to the described embodiments; the principle that the design is simply described described in above-described embodiment and specification; on the premise of without departing from the design spirit and scope; the invention also has various changes and modifications, in the range of these changes and improvements both fall within claimed the design.The invention claims scope and is defined by appending claims and equivalent thereof.
