Description
Technical field
The utility model relates to a kind of injection mold, especially relates to a kind of core-pulling mechanism of light fixture mould.
Background technology
In the design process of mould; for some elasticity profiled member preferably; can adopt forced demoulding mechanism; during the structures such as but it is comparatively complicated to work as profiled member, and the side has perforate, side is protruding, side is recessed, when the toughness of material own is relatively poor; when adopting forced demoulding mechanism to carry out the demoulding; easily damage forming part, greatly increase substandard products quantity, very unfavorable for the production control cost.
Chinese patent Granted publication number: CN201279867 provides a kind of forced demoulding mechanism July 29 2009 Granted publication day, and it comprises: a liftout plate, and it is located between the male model board and bottom plate in the mould; One Slanting pin mechanism, it is located on the described liftout plate; The last one taken off into sub-fixed head, and it is located in the male model plate; The last one taken off into son, and it is located at described taking off by force on the sub-fixed head, according to the needs of shape of product, take off by force sub-fixed head and change and difformly take off into son by force described, and the quantity into son taken off by force in increase and decrease; One return post, it is fixed on described liftout plate and described taking off by force between sub-fixed head; One thimble, it is located on the described liftout plate.Its weak point is, when the part that needs moulding during with side opening or side protruding (recessed), is adopting this strong mould emptier with the surface of die sinking perpendicular direction, carries out easily forming part being caused damage in the process of the demoulding.
The utility model content
The utility model be for overcome forced demoulding mechanism in the prior art easily when the demoulding to the deficiency of forming part injury, provide a kind of and extracted, guaranteed the moving core of side direction out part injury-free core-pulling mechanism smoothly.
To achieve these goals, the utility model is by the following technical solutions:
The core-pulling mechanism of a kind of light fixture mould of the present utility model, comprise solid plate, moving platen, be fixed with fixed die insert on the solid plate, be fixed with moving die insert on the moving platen, form die cavity between fixed die insert and the moving die insert, described moving platen is provided with the slideway of level towards the one side of solid plate, the take-up housing that is provided with the slide block of relatively slideway slip in the described slideway and is positioned at the slide block outside, is fixedly connected with slide block, described take-up housing is provided with the slide opening of inclination, is provided with an end and the relatively-stationary Angle Pin of solid plate in the described slide opening.During die sinking, in moving process, take-up housing and Angle Pin are to be slidingly connected at moving platen, therefore under the effect of Angle Pin and take-up housing slides laterally, the also outwards motion of pulling slide block, thus with the separating of the side of forming part, finish the side direction demoulding.In the process of dynamic model die sinking, finish the demoulding of part, avoid simultaneously part to sustain damage, guaranteed the quality of part.
As preferably, described take-up housing is provided with some projections in the one side that contacts with slide block, and described slide block is provided with the pit that matches with projection.Pit and projection cooperate, and are convenient to slide block and take-up housing location and installation between the two.
As preferably, be respectively equipped with press strip between described slideway two opposed inner walls and the take-up housing, described press strip is provided with chute, and the two sides that described take-up housing contacts with press strip are respectively equipped with the guide rib that can be complementary with chute.Be provided with press strip between take-up housing and the slideway, take-up housing and press strip generation relative sliding avoid take-up housing directly to contact with moving platen, and moving platen is played a protective role.
As preferably, be provided with the pin fixing with slide block in the described slide block.Pin and slide block are separated from each other, and the pin that only need more renew when product is retrofited gets final product, and has improved the versatility of mould, has prolonged the life-span of mould, has reduced production cost.
As preferably, described moving platen is provided be used to the slot to make way of dodging Angle Pin.Angle Pin just is present in the inside of mould like this, can not stretch out mould, avoided mould and other equipment on every side interference may, reduced simultaneously the volume of mould.
Therefore, the utlity model has following beneficial effect: (1) finishes the knockout course of side direction moving core in die sinking, guarantees the quality of part; (2) prolonged life-span of mould, and versatility is higher.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is right view of the present utility model.
Among the figure, Angle Pin 1, pin 2, take-up housing 3, moving platen 4, slot to make way 4a, slide block 5, moving die insert 6, fixed die insert 7, solid plate 8, press strip 9.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of core-pulling mechanism of light fixture mould, comprise solid plate 8, moving platen 4, be fixed with fixed die insert 7 on the solid plate 8, be fixed with moving die insert 6 on the moving platen 4, form die cavity between fixed die insert 7 and the moving die insert 6, moving platen 4 is provided with the slideway of level towards the one side of solid plate 8, be provided with slide block 5 and take-up housing 3 in the slideway, and slide block 5 relatively slideway slides, take-up housing 3 is positioned at slide block 5 outsides, and is fixedly connected with slide block 5.Take-up housing 3 is provided with the slide opening of inclination, is provided with Angle Pin 1 in the slide opening, and an end of Angle Pin 1 is relative fixing with solid plate 8, and Angle Pin 1 relatively slide opening slides.Take-up housing 3 is provided with two projections in the one side that contacts with slide block 5, lays respectively at the up and down both sides of this contact-making surface, and slide block 5 is provided with the pit that matches with projection, is convenient to both and positions.Be provided with the pin 2 of fixing with slide block 5 in the slide block 5.Moving platen 4 is provided with slot to make way 4a, is used for dodging Angle Pin 1.As shown in Figure 2, be respectively equipped with press strip 9, two press strips 9 between slideway two opposed inner walls and the take-up housing 3 and be provided with relative chute, the two sides that take-up housing 3 contacts with press strip 9 are respectively equipped with the guide rib that can be complementary with chute.
Among the process of die sinking, moving platen 4 is moving down, because but take-up housing 3 and Angle Pin 1 are relative slidings, take-up housing 3 is therefore under the effect of Angle Pin 1 and slide laterally, also outwards motion of pulling slide block 5 during slip, make the separating of side of slide block 5 and forming part, thereby finish the side direction demoulding.Namely in the process of moving platen die sinking, just can finish the side direction demoulding of part.
