Abstract
There is the high-precision mold auxiliary guide of pointed cone structure, patrix (2) on core rod and counterdie (5) arrange lead (3) and lead (4) respectively, during matched moulds, lead (3) inserts guiding post holes (4), the shape of lead (3) and guiding post holes (4) all has tapered side, and lead (3) and guiding post holes (4) end are respectively pointed cone and pointed cone hole shape.The mould core utilizing compacting or multiple pressure to produce pressing adopts the utility model auxiliary guide, and the coupling of tapered side contributes to the coincideing without skew of whole core rod.
Description
Technical field
The utility model relates to the preparation of high-precision mold.
Background technology
The application of current mould relates to every product (large as automobile, space flight, commodity, electrical equipment communication, medical product equipment etc.), as long as the many product of quantity all can apply mould production, and mould bases is mould inalienable part.Current to mould bases required precision, can determine by product demand by different levels.Mould bases is the crude product of mould, is made up of, can be described as the skeleton of whole set of die various different steel plate mating parts.
Mould bases is also mold base, or die holder.The pedestal of mould, is convenient to installation mold, rises and supports, protection, the effect of the critical component (core rod) of connecting mold.Because mold base does not participate in shaping, so its shape does not have to change with the change of component, only with the size of component, structure is relevant, so can by mold base standardization, namely mold base form broadly similar, only has size, and thickness changes, standardization aft-loaded airfoil gets up very convenient, mold base factory first can process the mold base part (template, guide pillar) etc. of specification of all sizes, then needs to form a set of mold base according to client.Mould bases has pre-shaping device, positioner and liftout attachment.Generally be configured to panel, A plate (front model), B plate (rear model), C plate (square iron), base plate, thimble panel, Ejector Retainer Plate and the spare and accessory parts such as guide pillar, back stitching.The most basic requirement of one secondary standard mould bases needs smooth die sinking exactly.Whether smooth die sinking is, with the precision in 4 guide pillar holes, directly related.So ordinary circumstance all needs to carry out rapid drilling then bore hole, to reach precision by CNC vertical machining centre.Especially mould bases relative volume is large, and mould bases is on-line equipment (as injection machine, die casting machine etc.) on forming machine, and therefore, the precision of 20 microns has been the mould bases of very high degree of precision.
Because core rod may have more high accuracy, practice needs the mould bases reaching 5-10 micron accuracy, may core rod be damaged when the mould bases of above-mentioned 20 micron accuracy is applied, add that the precision of forming machine itself may be also restricted.
Utility model content
The utility model object proposes a kind of high-precision mold auxiliary guide with pointed cone structure, especially core rod may have the normal work that more high accuracy can ensure mould bases and mould, the machining accuracy of suppressing can be ensured, and the working life of core rod can be ensured, it is when adopting high-precision core rod application of installation, during precision higher than mould bases itself of the required precision of high-precision core rod.
The technical solution of the utility model is, there is the high-precision mold auxiliary guide of pointed cone structure, patrix 2 on core rod and counterdie 5 arrange lead 3 and guiding post holes 4 respectively, during matched moulds, lead 3 inserts guiding post holes 4, the shape of lead 3 and guiding post holes 4 all has tapered side, and lead 3 and guiding post holes 4 end are respectively pointed cone and pointed cone hole shape.
After lead 3 coincide with guiding post holes 4, precision is identical with core rod.
On core rod patrix 2 and counterdie 5 arrange lead 3 and guiding post holes 4 be respectively provided with two to four right.
The beneficial effects of the utility model are, the mould core utilizing compacting or multiple pressure to produce pressing adopts the utility model auxiliary guide, the coupling of tapered side contributes to the coincideing without skew of whole core rod, this is the most flimsy reason of existing high accuracy core rod, and lead 3 and guiding post holes 4 end are respectively pointed cone and the accurate positioning of pointed cone hole shape, easily process again.And of the present utility model may be used for precision slightly poor mould bases and pressure forming machine (as injection machine etc.).
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Bearing type die set guide pin 1, patrix 2, lead 3, guiding post holes 4, counterdie 5.
Detailed description of the invention
As shown in the figure, Fig. 1 is the utility model typical mould structure chart.Top is called patrix, and lower part is called counterdie.During injection moulding, upper and lower mould can first combine, and makes plastics shaping in upper and lower mould formation of lots part.Then upper and lower mould can separate, and is released by finished product by the liftout attachment based on counterdie.
The utility model structure comprises patrix 2 on core rod, patrix install on lead 3, counterdie 5 installs guiding post holes 4.Also patrix can be installed on guiding post holes 4, counterdie 5 and lead 3 is installed; Bearing type die set guide pin 1 is the guide pillar on the mould bases of core rod installation; mould bases is lead 3 also folding in guiding post holes 4 when matched moulds or die sinking, and lead 3 and guiding post holes 4 end are respectively pointed cone and the accurate positioning of pointed cone hole shape, and core rod can not be made to offset; for auxiliary accurately location, thus protection core rod.
The utility model is contained on core rod, and core rod can be applied on such as injection machine, die casting machine and mold portions is combined by the rule of existing maturation and position and fixed.After lead 3 coincide with guiding post holes 4, precision is identical with core rod, as also reached 5-10 micron.
