Abstract
The utility model discloses an effectual injection mold of shaping, including movable mould and cover half, the bottom of cover half is provided with the hydro -cylinder, be connected with the fixed block of its promotion of accessible on the hydro -cylinder, the both ends of fixed block be provided with can stretch into to thimble in the die cavity of cover half. The thimble that can stretch into to die cavity in is set up through the below at the cover half to through oil cylinder drive, before the mould material got into the die cavity aftershaping, control oil cylinder drive thimble was ejecting, formed certain impact force in the part, thereby formed the aperture, made aperture shaping surfacing smooth, and did not have the bubble.
Description
Technical field
The utility model has related to a kind of injection mold of good forming effect, belongs to injection-moulding device technical field.
Background technology
In injection molding process, some product needed forms aperture on surface, is convenient to later stage location or fixing using. But existing injection mold normally adopts in the time of aperture moulding, by relief in mould material inflow die cavity, it forms automatically, but in the process automatically forming, have owing to there is no certain impulsive force, around aperture, easily form bubble, and surface is smooth not smooth.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of injection mold of good forming effect, by utilizing oil cylinder that thimble is ejected before mould is anticipated type, produce certain impulsive force in part, thereby form aperture, make aperture molded surface smooth smooth, and there is no bubble.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
An injection mold for good forming effect, comprises dynamic model and cover half, and the bottom of described cover half is provided with oil cylinder, is connected with and can passes through the fixed block of its promotion on described oil cylinder, and the two ends of described fixed block are provided with the thimble in the die cavity that can stretch to described cover half.
The injection mold of aforesaid a kind of good forming effect, is characterized in that: the two ends, bottom of described cover half are also fixedly installed respectively back-up block, and the height of described back-up block is higher than the height of described oil cylinder.
The injection mold of aforesaid a kind of good forming effect, is characterized in that: described cover half lower surface is also provided with the groove for placing oil inlet pipe.
The injection mold of aforesaid a kind of good forming effect, is characterized in that: between described two back-up blocks, be also provided with connecting plate, and be provided with perforate on described connecting plate, described cover half charging aperture extends in described perforate.
The injection mold of aforesaid a kind of good forming effect, is characterized in that: the gauge tap of described oil cylinder and the electrical connection of the pay-off of injection mold.
The beneficial effects of the utility model: by the thimble that can stretch in die cavity is set below cover half, and pass through hydraulic oil cylinder driving, before mould material enters die cavity aftershaping, controlling hydraulic oil cylinder driving thimble ejects, form certain impulsive force in part, thereby formation aperture, makes aperture molded surface smooth smooth, and there is no bubble.
Brief description of the drawings
Fig. 1 is the upward view of the injection mold of a kind of good forming effect of the utility model;
Fig. 2 is the structural representation after the cover half of the injection mold of a kind of good forming effect of the utility model dissects.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As depicted in figs. 1 and 2, a kind of injection mold of good forming effect, a kind of injection mold of good forming effect, comprise dynamic model 1 and cover half 2, the bottom of described cover half 2 is provided with oil cylinder 4, on described oil cylinder 4, be connected with and can pass through the fixed block 9 of its promotion, the two ends of described fixed block 9 are provided with the thimble 8 in the die cavity that can stretch to described cover half 2, by the thimble 8 that can stretch in die cavity is set below cover half 2, and drive by oil cylinder 4, before mould material enters die cavity aftershaping, controlling hydraulic oil cylinder driving thimble 8 ejects, form certain impulsive force in part, thereby formation aperture, make aperture molded surface smooth smooth, and there is no bubble.
The two ends, bottom of described cover half 2 are also fixedly installed respectively back-up block 3, and the height of described back-up block 3 is higher than the height of described oil cylinder 4, be convenient to oil cylinder 4 to be fixed on the bottom of cover half 2, described cover half 2 lower surfaces are also provided with the groove 6 for placing oil inlet pipe, be convenient to oil inlet pipe to be fixed in groove 6, be difficult for sustaining damage.
Between described two back-up blocks 3, be also provided with connecting plate 5, and be provided with perforate on described connecting plate 5, described cover half 2 charging apertures 7 extend in described perforate, and charging aperture 7 is extended, and are convenient to charging.
The gauge tap of described oil cylinder 4 and the electrical connection of the pay-off of injection mold, after pay-off feeding completes, in mould material enters die cavity, the rear oil cylinder 4 of controlling ejects, and generally completes 0.1 second rear drive oil cylinder in feeding, is convenient to the rapid shaping of aperture.
In sum, the utility model provides a kind of injection mold of good forming effect, by utilizing oil cylinder that thimble is ejected before mould is anticipated type, produces certain impulsive force in part, thereby forms aperture, makes aperture molded surface smooth smooth, and there is no bubble.
More than show and described general principle of the present utility model, principal character and advantage. The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model is by appending claims and equivalent circle thereof.
