Description

The injection molding of sanding machine key

Technical field

The utility model patent is related to the injection molding of sanding machine key, belongs to injecting molding die, is mainly used for heat The key of thermoplastic plastic injection moulding sanding machine.

Background technique

Sanding machine is for carrying out a kind of manual power tool of metal surface grinding process, specifically for steel, aluminium, copper etc. The surface of metal product carries out effect process, can produce the different snowflake line of various precision, drawing pattern, ripple glaze, matte surface, Mirror surface etc., Rapid-Repair depth scratch and slightly scratches, quick grinding and buffing.The sanding machine of different styles, switch key Pattern it is different.Key mold design, original design use shree plates mold, spot pouring mouth injection moulding, condensation material and modeling Part convenient separation, but plastic filling difficulty occur and be not fully filled phenomenon；It is filled with to plastic, injection pressure or note need to be increased It penetrates the time, but injection pressure increases and occur finning, increase injection time reduces production efficiency.

Summary of the invention

In order to preferably solve the problems, such as to appear above, it is simple, easily fabricated that the utility model patent provides a kind of structure Mold.

The technical solution of the utility model patent is: the injection molding of sanding machine key, including cover half and dynamic model, cover half Be made of top clamping plate, locating ring, sprue bush, solid plate, latch segment, guide sleeve, inclined guide pillar, type chamber, locating ring by screw with Top clamping plate is coupled, and sprue bush runs through top clamping plate and solid plate, is interference fitted with it, and inclined guide pillar is installed in latch segment, lock Tight block, type chamber are coupled with solid plate with screw, and guide sleeve runs through solid plate, are interference fitted with it；Dynamic model by Bottom clamp plate, cushion block, Thimble, sprue puller, release link, guide post, moving template, angled-lift splits, type core, push plate, thimble fixed plate are constituted, and angled-lift splits can be in dynamic model It is slided in plate, type core is coupled with moving template with screw, and guide post runs through moving template, is interference fitted with it, thimble, sprue puller, reset Bar is installed in thimble fixed plate, and runs through moving template, and thimble fixed plate is coupled with push plate with screw, cushion block, Bottom clamp plate with Moving template is coupled with screw, and cushion block is coupled with Bottom clamp plate with screw.

In the mold, thimble, sprue puller, release link, thimble fixed plate, push plate can move together in whole, thimble, drawing Expect that bar runs through type core, release link is four, is evenly distributed on moving template.

In the mold, moving template upper surface opens up groove, and angled-lift splits can be moved from inside to outside along groove, are fixed on outside groove The screw at end limits its movement.

This mould structure is simple, easily fabricated, easy to use, can smoothly inject and ejection key plastic.

Detailed description of the invention

Fig. 1 is key, and Fig. 2 is mode host visual pattern, and Fig. 3 is mold left view, and Fig. 4 is moving template.

In Fig. 2 and Fig. 3,1. Bottom clamp plates, 2. cushion blocks, 3. sprue pullers, 4. moving templates, 5. inclined guide pillars, 6. angled-lift splits, 7. locks Tight block, 8. solid plates, 9. top clamping plates, 10. sprue bush, 11. locating rings, 12. type chambers, 13. type cores, 14. thimble fixed plates, 15. push plate, 16. release links, 17. thimbles, 18. guide sleeves, 19. guide posts.

Specific embodiment

With reference to attached drawing 2 and Fig. 3, the injection molding of the utility model sanding machine key, including cover half and dynamic model, cover half by Top clamping plate 9, locating ring 11, sprue bush 10, solid plate 8, latch segment 7, guide sleeve 18, inclined guide pillar 5, type chamber 12 are constituted, locating ring 11 are coupled by screw with top clamping plate 9, and sprue bush 10 is interference fitted, inclined guide pillar 5 through top clamping plate 9 and solid plate 8 with it It is installed in latch segment 7, latch segment 7, type chamber 12 are coupled with solid plate 8 with screw, and guide sleeve 18 runs through solid plate 8, with its interference Cooperation；Dynamic model is by Bottom clamp plate 1, cushion block 2, thimble 17, sprue puller 3, release link 16, guide post 19, moving template 4, angled-lift splits 6, type Core 13, push plate 15, thimble fixed plate 14 are constituted, and angled-lift splits 6 can slide in moving template 4, and type core 13 and moving template 4 use screw It is coupled, guide post 19 runs through moving template 4, is interference fitted with it, thimble 17, sprue puller 3, release link 16 are installed on thimble fixed plate 14 In, and running through moving template 4, thimble fixed plate 14 is coupled with push plate 15 with screw, and cushion block 2, Bottom clamp plate 1 and moving template 4 use spiral shell Nail is coupled, and cushion block 2 is coupled with Bottom clamp plate 1 with screw.

In the mold, thimble 17, sprue puller 3, release link 16, thimble fixed plate 14, push plate 15 one can be started shipment in whole Dynamic, thimble 17, sprue puller 3 run through type core 13, and release link 16 is four, are evenly distributed on moving template 4.

With reference to attached drawing 4, in the mold, dynamic model, 4 upper surfaces open up groove, and angled-lift splits 6 can move from inside to outside along groove, The screw for being fixed on groove outer end limits its movement.

The mold, move, cover half molding when, molten plastic is injected into mold, after plastics solidification after, one side of dynamic model to Lower movement, sprue puller 3 simultaneously pull out condensation material from sprue bush 10, and angled-lift splits 6 are moved out along inclined guide pillar 5, angled-lift splits 6 First side core is driven to complete core pulling from plastic side, stops fortune when the screw on the outside of angled-lift splits 6 encounter 4 upper groove of moving template It is dynamic.Dynamic model moves a distance stop motion, under the mandril effect of injector, drives push plate 15 and thimble 17 by plastic from type It is ejected on core 13.When molding, release link 16 is contacted with solid plate 8 drives thimble 17, sprue puller 3, thimble fixed plate 14 and push plate 15 return to original position.
