Description
Technical field
The present invention relates to the parts technical field of plastic cement products mould, particularly relate to a kind of simple alignment pin.
Background technology
Along with improving constantly of technology, the fast development of plastic cement products industry, the diversification structure of all kinds of plastic cement parts becomes increasingly complex, quality requirements is the strictest, the highest to plastic cement products industry requirement, competition is the fiercest, how to ensure that similar plastic cement products occurs without exception, the production cycle that maximized guarantee Product processing is effective, stable in process of production.Alignment pin is an important accessory, used by it is main it is, it is used in injection mold, by front mold core plates, mold cavity plate and three pieces of plate location of rear mold core plates, it is ensured that product die cavity pretty good invariant position shape, if location inaccuracy, reduce the yield rate of product, cost of idleness, and the necessary simple in construction of alignment pin, easy accessibility.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of simple alignment pin.
The technical solution of the present invention is achieved in that a kind of simple alignment pin, including cylindric location bar and the fixing seat of hollow；Contiguous block is also set up on described fixing seat；Described contiguous block is cylindrical, and upper end is provided with flat recess；A manhole being perpendicular to axle center it is further opened with on the bar of described location.
Preferably, described location bar is provided with an annular groove.
Preferably, described manhole runs through bar both sides, location sidewall.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The alignment pin of the present invention, simple in construction, reasonable in design, and it is convenient to dismounting, and be prevented effectively from rigging error occurs, it is remarkably improved Product Precision.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the alignment pin of the present invention.
Wherein: 1, location bar；2, fixing seat；3, contiguous block；4, flat recess；5, manhole；6, annular groove.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The alignment pin of the present invention, as shown in Figure 1, including cylindric location bar 1 and the fixing seat 2 of hollow；Contiguous block 3 is also set up on described fixing seat 2；Described contiguous block 3 is used for connecting assembly above, and its location bar is for positioning lower section assembly；Described contiguous block 3 is cylindrical, and upper end is provided with flat recess 4, and alignment pin is extracted by convenience magnetic screw driver；A manhole 5 being perpendicular to axle center it is further opened with on the bar of described location.
Further instruction, described location bar is provided with an annular groove 6.
Further instruction, described manhole 5 runs through bar both sides, location sidewall, laterally fixes for bottom.
The processing technique of a kind of alignment pin, comprises the following steps:
(1), rough forging；
(2), numerical control lathe wheeled litter outline and bore hole；
(3), finish-milling；
(4), quenching；
(5), sandblasting；
(6), circle mill；
(7), essence flat stone mill；
(8), precision WEDM machine；
(9), pincers worker deburring；
(10), inspection warehouse-in.
The alignment pin of the present invention, simple in construction, reasonable in design, and it is convenient to dismounting.The alignment pin of the present invention uses the technique such as numerically controlled lathe, precision WEDM machine, is prevented effectively from and rigging error occurs, is remarkably improved Product Precision.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
