Abstract
The utility model relates to an inner core-pulling core mould, which belongs to the technical field of a mould. The inner core-pulling core mould comprises a movable template, a movable mould fixing plate, a fixed template and a fixed mould fixing plate; the movable template is fixed on the movable mould fixing plate through a packing block and a supporting plate, wherein, a push plate is movably arranged on the movable mould fixing plate; a top rod fixing plate is arranged on the push plate, and a top rod is fixed on the push plate through the top rod fixing plate; a slant sliding guide hole is arranged inside a movable mould core; an inner core-pulling molding core which can be slid along the slant sliding guide hole is arranged at the upper part of the top rod, and a molding groove used for buckling bulge molding is arranged on the inner core-pulling molding core. The inner core-pulling core mould has the advantages that the structure is simple, stable and reliable, the integrality is high, the service life of the mould is greatly prolonged, and the production, the on-site dismounting by bench workers and the maintenance are easy.
Description
Technical field
The utility model relates to a kind of mould of plastics, is specifically related to a kind of by being pumped into type core film tool mechanism in the top rod driving.
Background technology
Plastic injection mould is an instrument of producing plastic products, uses very extensive.In some plastic products injection moulding, because plastic products are provided with the buckle projection vertical with the mold releasability direction, such as the loam cake that cooperates with the fuse box main body shown in Figure 1, at the sidewall part protruding buckle is arranged, make it to cooperate the recessed position of main body to be used, and identical good with main body, convenient fastening and button with main body opened.Therefore all be provided with the inner core pulling structure in many mould of plastics, taking out structure in using always at present is curved oblique internal core-pulling mechanism of pin and angle ejector rod core-pulling mechanism, needs twice parting mechanism during the former die sinking, and structure is comparatively complicated; Latter's mould structure needs the bigger space that ejects, and has when installation mold bulk under the situation of limitation, arranges design very difficult.In addition, if this inner core pulling structure stroke is long, angle ejector rod is stressed excessive, can cause the flexural deformation of angle ejector rod angle ejector rod or fractures and mold damage, thereby influence the precision of goods and the service life of mould.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be convenient to process, be pumped into the type core mold in globality is strong, precision is easy to guarantee.
The purpose of this utility model is achieved through the following technical solutions:
Be pumped into the type core mold in of the present utility model, comprise moving platen, dynamic mould fixing plate, solid plate and cover half fixed head, moving platen is fixed on the dynamic mould fixing plate by cushion block and gripper shoe.Wherein be movably set with push pedal on dynamic mould fixing plate, be provided with the push rod fixed head in push pedal, push rod is fixed in the push pedal by the push rod fixed head.Dynamic mould core inside is provided with oblique slide guide hole, push rod top be provided with can slide along oblique slide guide hole in be pumped into the type core, in be pumped into the type core and be provided with the shaping groove that is used for the moulding of buckle projection.
The beneficial effects of the utility model are: the utility model is simple in structure, reliable and stable, globality is strong, prolonged the service life of mould greatly, be easy to produce dismounting and maintaining with on-the-spot pincers worker, precision of plastic also is easy to guarantee in addition, has improved the quality of plastic significantly.
Description of drawings
Fig. 1 is the structural representation of the utility model film tool.
The figure number explanation:
1 cover half fixed head, 2 solid plates, 3 die cavity pieces, 4 dynamic mould cores
Be pumped into type core 6 moving platens 7 push rods 8 support plates in 5
9 cushion blocks, 10 push rod fixed heads, 11 push pedals, 12 dynamic mould fixing plates
The specific embodiment
As Fig. 1, to be pumped into the type core mold in of the present utility model and to comprise moving platen 6, dynamic mould fixing plate 12, solid plate 2 and cover half fixed head 1, moving platen 6 is fixed on the dynamic mould fixing plate 12 by cushion block 9 and gripper shoe 8.Wherein, be movably set with push pedal 11 on dynamic mould fixing plate 12, be provided with push rod fixed head 10 in push pedal 11, push rod 7 is fixed in the push pedal (11) by push rod fixed head 10.Dynamic mould core 4 inside are provided with oblique slide guide hole, push rod 7 tops be provided with can slide along oblique slide guide hole in be pumped into type core 5, in be pumped into type core 5 and be provided with the shaping groove that is used for the moulding of workpiece buckle projection.
In the utility model on the dynamic mould core gradient of slide guide hole should specifically set according to the angle of workpiece buckle projection, can smoothly the buckle projection be deviate to be pumped into the type core in guaranteeing.
Operation principle of the present utility model is as follows:
As shown in Figure 1, the moulding mold cavity forming that the moulding of workpiece is made up of die cavity piece 3 and dynamic mould core 4, in be pumped into shaping groove on the type core 5 and finish the protruding moulding of buckle on the workpiece inwall.
When injecting the back die sinking, dynamic model partly moves down, and the hydraulic cylinder of injector is started working, and is pumped into type core 5 in the push rod 7 in the ejecting mechanism of mould promotes, and is pumped into type core 5 in making and stretches out dynamic mould core 4.In be pumped into type core 5 when stretching out dynamic mould core 4 also to dynamic mould core 4 medial movement, follow at the slide guide hole of dynamic mould core 4 protruding when ejecting workpiece again, in be pumped into the inwardly motion inwall buckle projectioies of inwardly deviating from goods of type core 5 along bevel direction, goods are deviate from from dynamic mould core 4 smoothly.During the mould matched moulds, the restoring force that relies on the compression spring on the release link in the mould that resets of push rod 7 resets ejecting mechanism drive push rod 7; Continue matched moulds, in be pumped into type core 5 and reset under the contact pressing effect of die cavity piece 3, be pressed in the slide guide hole of dynamic mould core 4 band angles, finish injection molding once circulation.
