Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
One of core idea of the present utility model is, insert-molding technology is incorporated in magnetic card magnetic head assembling prioritization scheme, simultaneously in conjunction with automatic technology, improves magnetic card magnetic head efficiency of assembling.
So-called insert-molding (insert molding) refers to and in mould, packs resin by injection after pre-prepd different material inserts into, and the material of melting is combined curing with inserts, make the moulding engineering method of integration product, also referred to as integrated injection molding technology.Many dissimilar article all can be used as inserts, comprise cable, connector, spring and nut etc.In injection-molded finished, stud with metal insert and be in order to improve the working strength of plastic product and to increase the practical application of finished product, as improvement electric conductivity or convenient and being connected of other part etc.In each embodiment of the utility model, magnetic core group together with being assemblied in line bag between magnetic core group, spacer shims as inserts.
The production method embodiment that introduces a kind of magnetic card magnetic head that the utility model provides below, with reference to Fig. 3, shows the process flow diagram of the production method embodiment mono-of the utility model magnetic card magnetic head, comprising:
In step 31, the concrete quantity of magnetic core group is determined by shape, thickness and the product type of magnetic core, and a magnetic card magnetic head generally needs 2 above magnetic core groups, and each magnetic core group is comprised of several loose sheet magnetic cores.Particularly, above-mentioned magnetic core group can be welded by several loose sheet magnetic cores.
Above-mentioned mold cavity is comprised of upper die and lower die.Because the inserts in the utility model embodiment is different many, be assembled together, then put into mould fixed bit.Therefore, first to guarantee the precision of assembling, then consider the locator meams in mould.Through overtesting comparison, determine the mode auxiliary positioning that adopts side slide in mould, can guarantee the size tolerance requirements of injection moulded products, so the utility model embodiment adopts the location of the auxiliary inserts of mode of side slide.Because those skilled in the art can predict the structure of upper model cavity by the shape of counterdie die cavity and inserts, again because left and right sides slide block structure is identical, position is symmetrical, therefore, mould schematic diagram can omit the structural representation of model cavity and left slider, only illustrate the structure of counterdie die cavity and right side slide block, as shown in Figure 4.
Fig. 4 shows the counterdie die cavity of the utility model embodiment employing and the structural representation of right side slide block, comprises counterdie die cavity 41, gate location 42, inserts 43, right side slide block mold insert 44.Fig. 5 shows the enlarged diagram of the inserts 43 that in Fig. 4, A partly indicates, and inserts 43 is comprised of some magnetic core groups 12, line bag 13, spacer shims 14.When assembling, by assemble sequence, be positioned in counterdie die cavity 41.
In this step 31, the grouping of magnetic core group 12 can be artificial grouping, also can adopt the modes such as mechanical touch sense to carry out magnetic core grouping.
The operating process of artificial grouping is: operating personnel adopts the instruments such as tweezers that magnetic core group is clamped, and puts into successively the rigging position of the magnetic core group that the first mold cavity is corresponding.
