Description
Technical field
This utility model relates to injection mold technical field, is specially a kind of efficiency compact high injection mold.
Background technology
Generally, being removed from the molds finished product, no matter be adopt the single or ejecting mechanism of multicomponent, it ejects action is all once complete.But owing to the shape of finished product is special, or requirement during volume production, if after once ejecting, finished product remains in die cavity, or cannot Automatic-falling time, it is necessary to be further added by once ejecting action.Such eject movements design, be called Double-ejection.
Development along with science and technology, the precision that injecting products produces is received more and more attention, for some little parts, specific demand due to product structure, less ejecting mechanism is needed to complete die sinking process, therefore for injection mold, the reasonability of its structural design has just welcome higher requirement.General, demand due to product structure, product structure needs little thimble to eject, generally we adopt and little thimble are placed on the scheme on upper ejector retainner plate, but owing to the diameter of little thimble is very thin, long plus mould ejection stroke, length along with little thimble is also required to lengthen simultaneously, therefore little thimble is when ejecting, owing to its length is long, toughness and intensity are relatively low, deformation or breakage phenomenon often occur, not only result in later stage die trial progress and also add the later stage amendment difficulty, increase artificial and material cost, therefore final structure is false and does not reach the effect that ejects.
Utility model content
The purpose of utility model: in order to overcome above deficiency, the open a kind of efficiency compact high injection mold of this utility model, there is reasonable in design, compact conformation, eject that intensity is big, working (machining) efficiency is high, save the advantages such as cost.
Technical scheme: in order to realize object above, the utility model discloses a kind of efficiency compact high injection mold, including moving platen and be positioned at the mavable module core within moving platen, ejecting mechanism, mould foot, backing plate, bottom plate；Described mould foot is positioned at the both sides of bottom plate；Described moving platen is located at the top of mould foot；Described ejecting mechanism include the little thimble between moving platen and bottom plate, upper plate, lower roof plate, pull bar, big thimble, on ejector retainner plate, the fixing top board of pull bar and lower ejector retainner plate；Described little thimble is fixing to be located on upper plate；Described upper plate and the fixing connection of lower roof plate, and be fixed on moving platen by alignment pin；Described big thimble is fixedly mounted on ejector retainner plate；Described upper ejector retainner plate is fixedly mounted on above lower ejector retainner plate；One end of described pull bar is connected with lower roof plate, and the other end is fixing with the fixing top board of pull bar to be connected；The fixing top board of described pull bar is arranged on the inside of lower ejector retainner plate by shutter；Described backing plate is fixed at the central authorities of bottom plate；The fixing top board of described pull bar is positioned at the surface of backing plate.
This utility model is reasonable in design, by adopting little thimble and big thimble to coordinate the scheme of Double-ejection, decrease the ejection stroke of little thimble, it is to avoid thimble in ejection process because the deformation that causes of intensity deficiency or the problem that fractures, it is ensured that mould eject success rate.It addition, the fixing top board of pull bar described in the utility model is connected with lower ejector retainner plate by shutter, described shutter is capable of lower ejector retainner plate and fixes separating of top board with pull bar, and then realizes the pushing method of Double-ejection；Ensure that the reasonability of this Machine Design；Meanwhile, this utility model also has saving cost, working (machining) efficiency advantages of higher, has the very big market competitiveness.
Further, above-mentioned a kind of efficiency compact high injection mold, described lower roof plate central authorities are provided with "T"-shaped draw-in groove；Described "T"-shaped draw-in groove cooperates with the "T"-shaped structure at pull bar top and is connected.Lower roof plate adopts "T"-shaped draw-in groove to be connected with pull bar, replaces the fixing connection of traditional mechanical system, ensures that the inconsistent phenomenon that lower roof plate and pull bar cause due to position skew in mutual motor process has enough cushion spaces on the one hand, it is to avoid rigid cooperation occur；On the other hand, simple in construction, easy maintenance and replacement, improve the scope of application of product.
Further, above-mentioned a kind of efficiency compact high injection mold, the top of described little thimble is cased with mold insert；Described mold insert is located at inside mavable module core.Top area at little thimble is provided with mold insert, facilitates the installation of product and the processing adjustment in later stage, additionally, little thimble can also be played fixed guide effect by mold insert, what be further ensured that little thimble makes intensity, it is to avoid deformation or the phenomenon fractureed occurs, improves the service life of little thimble.
Further, above-mentioned a kind of efficiency compact high injection mold, described shutter is that interference fit is connected with the mode of being connected of lower ejector retainner plate.By the connected mode of interference fit, it is ensured that in ejection process, before upper plate does not encounter moving platen, the clamping force that lower ejector retainner plate produces due to interference fit drives pull bar to move upwardly together, it is ensured that once eject the realization of action, simple in construction, design ingenious.
Further, above-mentioned a kind of efficiency compact high injection mold, described bottom plate is provided with and ejects hole with injection machine top roller matches.
Further, above-mentioned a kind of efficiency compact high injection mold, described upper ejector retainner plate is provided with steam vent.Owing to being interference fit between shutter and lower ejector retainner plate, by arranging steam vent, it is ensured that the air pressure of the chamber that shutter is formed with upper ejector retainner plate, lower ejector retainner plate keeps balance with extraneous, it is to avoid mechanical stress occur.
Technique scheme is it can be seen that a kind of efficiency compact high injection mold described in the utility model has the advantages that
A kind of efficiency compact high Injection Mold Design described in the utility model is reasonable, compact conformation；By adopting little thimble and big thimble to coordinate the scheme of Double-ejection, decrease the ejection stroke of little thimble, it is to avoid thimble in ejection process because the deformation that causes of intensity deficiency or the problem that fractures, it is ensured that mould eject success rate.It addition, the fixing top board of pull bar described in the utility model is connected with lower ejector retainner plate by shutter, described shutter is capable of lower ejector retainner plate and fixes separating of top board with pull bar, and then realizes the pushing method of Double-ejection；Meanwhile, this utility model also has saving cost, working (machining) efficiency advantages of higher, has the very big market competitiveness.
