Abstract
An injection mold positioning column is characterized in that the injection mold positioning column comprises an upper positioning block and a lower positioning block; the lower positioning block is composed of a shoulder and a positioning frustum located on the shoulder; the upper positioning block is provided with a conical hole matched with the positioning frustum, and a transverse groove penetrating though the conical hole is formed in the conical hole. According to the injection mold positioning column, in the direction where the positioning precision requirement is high, the frustum and the solid conical hole are adopted for positioning; in the other direction, the transverse groove is formed, the frustum and the solid conical hole are not used for positioning, and the positioning precision in the other direction is determined through positioning precision of the frustum and the solid conical hole; thus, the matching precision requirement for the frustum and the conical hole is lowered, the manufacturing precision requirement is lowered, and meanwhile the frustum and the conical hole can be engaged easily.
Description
Technical field
The invention relates to a kind of injection mold locating dowel, 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 the employing conical structure that lower locating piece has, upper locating piece is provided with the conical bore with Cone fit.Frustum, taper hole have corresponding quality of fit requirement, and in some cases, positioning precision often only has a direction to have the requirement of degree of precision, the auxiliary positioning that another direction can be high according to required precision.
Summary of the invention
According to above-mentioned requirements, the object of the invention is to provide a kind of injection mold locating dowel, in the direction that positioning accuracy request is high, adopt frustum and entity taper hole to locate, translot is offered in another direction, frustum is not located with taper hole entity, the precision that its positioning precision relies on frustum and taper hole entity to locate is determined, like this, just reduces the required precision that frustum coordinates with taper hole, reduce accuracy of manufacture requirement, make frustum easily engage with taper hole simultaneously.
For achieving the above object, the invention is realized by following technological means:
A kind of injection mold locating dowel, it is characterized in that: comprise locating piece and lower locating piece, described lower locating piece is made up of the location frustum takeed on, be positioned on shoulder, and described upper locating piece is provided with and the conical bore of locating frustum and coordinating, and described conical bore is provided with the translot running through conical bore.
Further:
The width of described translot is 2/3rds of location frustum outside diameter.
The material of described upper locating piece and lower locating piece is mould steel.
Described location frustum, conical bore surface adopts sulfurizing process.
Frustum upper end, described location adopts rounding structure.
Described mould steel model is SCM415.
The beneficial effect of the invention is: a kind of injection mold locating dowel that the invention provides, in the direction that positioning accuracy request is high, frustum and entity taper hole is adopted to locate, translot is offered in another direction, and frustum is not located with taper hole entity, and the precision that its positioning precision relies on frustum and taper hole entity to locate is determined, like this, just reduce the required precision that frustum coordinates with taper hole, reduce accuracy of manufacture requirement, make frustum easily engage with taper hole simultaneously.
Accompanying drawing explanation
Positioning block structure schematic diagram on Fig. 1, Fig. 2 is Fig. 1 upward view, and Fig. 3 is lower positioning block structure schematic diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the invention is further described.
As shown in drawings, a kind of injection mold locating dowel, it is characterized in that: comprise locating piece 1 and lower locating piece 6, described lower locating piece 6 is made up of shoulder 4, the location frustum 5 be positioned on shoulder 4, described upper locating piece 1 is provided with and the conical bore 2 of locating frustum 5 and coordinating, and described conical bore 2 is provided with the translot 3 running through conical bore 2.
Further:
The width of described translot 3 is 2/3rds of location frustum 5 outside diameter.According to positioning accuracy request, that determines frustum and taper hole coordinates area.
The material of described upper locating piece 1 and lower locating piece 6 is mould steel.
Described location frustum 5, conical bore 2 surface adopts sulfurizing process.Wear-resisting lubrication.
Frustum 5 upper end, described location adopts rounding structure.
Described mould steel model is SCM415.
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.
