Description
Technical field
The present invention relates to a kind of compression molding, be applicable to design of plastic molding die and manufacturing field in the machine industry with trapezoidal longitudinal guide lock construction.
Background technology
At present; Generally adopt " rectangle is vertically led lock " precision positioning one-mold multiple-member compression molding technology to produce long axis axle class thermosetting plastics spare both at home and abroad; Its key problem in technology is how to guarantee the dynamic radial positioning accuracy between various groove, thereby minimizing causes the products radial dimensional discrepancy because of upper and lower intermode mismatch.Two technical barriers appear in such mould in each manufacturer production of China is used: (1) must with the press and the supporting use of mould bases of high guiding accuracy; And the appointed condition of domestic each factory, mould bases accuracy of manufacture condition are uneven; Be difficult to generally adapt to, produce the adjustment difficulty, die life is low; (2) precision is led the lock processing difficulties, and the mold position precision of domestic imitation is low, and the percent defective of product is high, can only rely on import.
Summary of the invention
The object of the present invention is to provide a kind of long service life, technology is reasonable, positioning accuracy is high compression molding with trapezoidal longitudinal guide lock construction; The technology of the trapezoidal longitudinal guide lock construction of this mould is reasonable; Process easy; Dimensional accuracy is high, the be not stressed influence of machine precision and conventional mould bases precision of the positioning accuracy of mould, and the product percent defective is low.
The invention is characterized in: a kind of compression molding with trapezoidal longitudinal guide lock construction; Comprise upper die and lower die; It is characterized in that: said patrix and counterdie be respectively arranged be beneficial to longitudinally guiding, location between patrix and the counterdie lock the trapezoidal longitudinal guide lock that cooperates mutually, the upper end of said patrix is installed in upper grid, the lower end of said counterdie is installed in the downslide frid; Said upper grid, downslide frid arrive upper base plate, following seat board through locating piece and bolt respectively; Said upper die and lower die front side all is provided with location-plate under location-plate on the front side, the front side, and said upper die and lower die rear side all is provided with location-plate under location-plate on the rear side, the rear side, is located by last framed, low mold frame respectively about said upper die and lower die; Said framed through bolt to upper base plate, said low mold frame is fixed to down seat board through distance bolt.
Advantage of the present invention: adopt the upper die and lower die integral module to process simultaneously; The good manufacturability of mould structure; Effectively guarantee to have the positioning accuracy between the upper die and lower die of a plurality of type grooves, the simplified manufacturing technique flow process, practice thrift mold materials, thereby reduce die cost; Framed can be general, when producing the electric tool insulation rotor axle of different size,, can reduce production costs significantly as long as change corresponding compression molding, practice thrift the mould installation adjustment time; The last location-plate of the moulding upper die and lower die of employing standard and front side, rear side, following location-plate, design and when making the electric tool insulation rotor axle compression molding of different size only needs design cavity dimension and support holes size, and all the other sizes all are unified; Matched moulds has effectively been got rid of the influence of the systematic error of press and mould bases to insulation rotor axle precision to the upper and lower mould of moulding with the inclined-plane cooperation; Because the mould structure design has taken into full account the manufacturing process reasonability, can be convenient to after heat treatment, process, thereby guarantee shape, position and the dimensional accuracy at mould molding position again, guarantee the stability of production process technology with numerically controlled wire cutting machine.

The specific embodiment
With reference to figure 1; The parts of plastics 23 that insulation rotor axle 22 is coated is typical case's representatives of major axis bobbin class thermosetting plastics spare; Insulating layer material is epoxy resin M-230; Main technical requirements is: the plastic insulation layer thickness is even, guarantees the insulating properties requirement of armature spindle 22, and the axiality of axle journal and insulating surface is 0.05mm.
With reference to figure 2～4; A kind of compression molding with trapezoidal longitudinal guide lock construction; Comprise patrix 1 and counterdie 2; It is characterized in that: said patrix 1 and counterdie 2 be respectively arranged be beneficial to longitudinally guiding, location between patrix 1 and the counterdie 2 lock the trapezoidal longitudinal guide lock 3 that cooperates mutually, the upper end of said patrix 1 is installed in upper grid 4, the lower end of said counterdie 2 is installed in downslide frid 5; Said upper grid 4, downslide frid 5 are fixed to upper base plate 8, seat board 9 down through locating piece 6 and bolt 7 respectively; Said patrix 1, counterdie 2 front sides all are provided with on the front side location-plate 11 under location-plate 10, the front side, and said patrix 1, counterdie 2 rear sides all are provided with on the rear side location-plate 13 under location-plate 12, the rear side, and said patrix 1, counterdie about 2 are located by last framed 14, low mold frame 15 respectively; Saidly framed 14 and be fixed to upper base plate 8 through bolt 16, said low mold frame 15 is fixed to down seat board 9 through distance bolt 17.
In order to save mold materials, shorten the manufacturing cycle and to guarantee positioning accuracy; Said patrix 1, counterdie 2 adopt integral modules processing simultaneously after heat treatment, once accomplish the processing of patrix 1, counterdie 2 corresponding a plurality of trapezoidal longitudinal guides locks 3 and a plurality of cylindricality die cavity 1-2.
For quick locked mode, said patrix 1, counterdie 2 are respectively equipped with quick clamping apparatus 18, and said quick clamping apparatus 18 comprises location-plate 18-1 and flat head bolt 18-2, and said location-plate 18-1 is fixed on the screw boss 18-5 through bolt 18-3, pad 18-4.
