Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Disclose a kind of novel plastic compression molding with reference to figure 1 the present embodiment, comprise upper die component and lower mold assemblies, upper die component comprises seat of honour template 1, and seat of honour template 1 lower surface is provided with heating plate 2, and upper heating plate 2 lower surface center is provided with upper male mould 3; Lower mold assemblies comprises lower seat template 10, is provided with lower heating plate 16 above lower seat template 10, and lower heating plate 16 upper surface is installed with the lower punch 8 corresponding with upper male mould 3, is arranged with feed compartment 5, is arranged with impression bolster 7 outside feed compartment 5 outside lower punch 8; Be provided with the ejecting mechanism releasing plastic between lower seat template 10 and lower heating plate 16, ejecting mechanism comprises push pedal 13, and push pedal 13 upper surface is installed with ejector pin retaining plate 14, and ejector pin retaining plate 14 is vertically provided with push rod 15; Seat of honour template 1 is provided with guide pillar 17, lower seat template 10 is provided with the guide pin bushing 20 corresponding with guide pillar 17; Lower seat template 10 center is provided with the push rod 19 promoting ejecting mechanism, and push rod 19 is fixedly connected with push pedal 13 through after lower seat template 10.
In lower seat template 10, fixed vertical is provided with the push pedal guide pillar 12 to ejecting mechanism guiding, and push pedal 13 and ejector pin retaining plate 14 are all provided with the ejector guide pillar 11 corresponding with push pedal guide pillar 12; Cushion block 9 is connected with between lower seat template 10 and lower heating plate 16; Punch 8 is built-in with core 18; Impression bolster 7 is provided with side core 6, and side core 6 stretches to lower punch 8 through after impression bolster 7 and feed compartment 5 successively; Pressure block 4 is provided with between upper heating plate 2 and impression bolster 7.
After die sinking, poured into by the plastic raw materials prepared in the cavity of lower punch 8 and feed compartment 5, upper and lower mould closes and the plastics be loaded in cavity is heated pressurized, becomes molten condition and is full of whole die cavity, after plastics solidification is shaping, upper and lower mould is opened and is utilized ejecting mechanism to release plastic.
This novel plastic compression molding structure is simple, reasonable in design, easy to operate, and production process is comparatively simple, and convenient reinforced toward feed compartment 5, parts are few simultaneously, are convenient to maintenance and renewal part.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
