The beneficial effect of the utility model is: at the stroke of loosing core big and product to the also very big occasion of the power of holding tightly of core under, can reduce the diameter of employed pneumatic cylinder or hydraulic cylinder, reduce cost; Simultaneously can also be steadily, reliably core is loosed core.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is a kind of structural representation at the utility model T type groove place.
Among the figure: cover half 1, supporting seat 2, hydraulic cylinder 3, core 4, holder 5, guide pad 6, Connection Block 7, Angle Pin 8, T type groove 9, connecting axle 10, shaft coupling 11, piston rod 12, guide plate 13, guide chute 14, guide groove 15, pod 16, travel switch 17.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of structure of loosing core of die casting comprises core 4, hydraulic cylinder 3.Described hydraulic cylinder can also have pneumatic cylinder to replace.Core 4 inside are provided with the main cooling water passage that is the U type; Also be provided with the inferior cooling-water duct that is communicated with two parallel channels between two parallel channels of the main cooling water passage of the said U of being type, and the sectional area of inferior cooling-water duct is less than the sectional area of main cooling water passage.Hydraulic cylinder is provided with travel switch 17, controls the stroke of hydraulic cylinder through travel switch.
Be respectively equipped with relative upper edge, the two sides guide groove direction of guide plate 13, two guide plates on the relative two sides of said guide groove and be provided with the guide chute 14 that is parallel to each other, and guide chute is positioned at bottom, guide plate side.The bottom of holder 5 left and right sides is respectively equipped with slide block with respect to guide chute, and slidably between two guide plates, said slide block cooperates with guide chute holder.Core 4 is connected with holder 5 one ends, and the piston rod of hydraulic cylinder 3 is connected with the holder other end.
As shown in Figure 2, said T type groove 10 comprises the translot that links to each other with openend and is positioned at the pod 16 of T type trench bottom that the groove depth L of pod 16 is greater than the thickness H of T font connecting axle 10 heads and loosing core apart from sum of Angle Pin.Through this syndeton, can guarantee that hydraulic cylinder structure and the Angle Pin structure of loosing core of loosing core produces at the Shi Buhui of loosing core and interferes.Get in the process of die cavity at core, when hydraulic cylinder 3 promoted holders 5 and is in Angle Pin 8 and accomplishes when loosing core holder 5 residing final positions, hydraulic cylinder 3 quit work; Next promoting core 4 by Angle Pin 8 through mold clamping force gets in the die cavitys and is in the process of shaping position; Because the groove depth L of pod 16, that is to say that spacing between pod 16 and connecting axle 10 heads is greater than the distance of loosing core of Angle Pin greater than the thickness H of T font connecting axle 10 heads and loosing core apart from sum of Angle Pin; Therefore promote core 4 through mold clamping force at Angle Pin 8 and get in the die cavitys and be in the process of shaping position, can not produce interference between T type groove and the connecting axle.In the process of loosing core, at first overcome the hold power of product by Angle Pin 8 to core 4 through mould opening force, make between core and the product and throw off; In this process because the groove depth L of pod 16, that is to say that spacing between pod 16 and connecting axle 10 heads is greater than the distance of loosing core of Angle Pin greater than the thickness H of T font connecting axle 10 heads and loosing core apart from sum of Angle Pin; Therefore can not produce interference between T type groove and the connecting axle.
This programme is co-located on hydraulic pressure structure and the Angle Pin structure of loosing core of loosing core in the same structure of loosing core.When loosing core, at first overcome the hold power of product by Angle Pin 8 to core 4 through mould opening force, make between core and the product and throw off; Then in the process of loosing core that realizes big stroke through hydraulic cylinder 3.When core gets into die cavity, at first through holder 5 core 4 is pushed die cavity by hydraulic cylinder 3, the stroke of core 4 is controlled by travel switch 17.Promptly control the stroke of hydraulic cylinder 3, make holder 5 be in Angle Pin 8 and accomplish holder 5 residing final positions when loosing core through travel switch 17.Matched moulds pushes core 4 in the die cavity by Angle Pin 8 matching and fixing seats 5 and is in shaping position then.
