Abstract
The utility model discloses a casting ejection device which is composed of a connecting rod I, a three-way flange, an oil cylinder, a connecting rod II, ejector rods and the like. A gap A is formed in the position between the right side of the three-way flange and the step of the connecting rod II due to a nut, so that when mold releasing is conducted, ejector rods on the lower portion firstly make contact with the position with large workpiece mold holding force, and when the three-way flange moves rightwards by A, the connecting rod I and the connecting rod II impose even pushing force on the ejector rods simultaneously to eject the ejector rods out of a mold. By means of the casting ejection device, deformation of slab type parts in the casting and mold releasing process can be effectively prevented, and meanwhile the casting ejection device has the advantages of being advanced in process, simple in structure, safe and stable in performance and the like.
Description
Technical field
The utility model relates to a kind of die casting ejector apparatus.
Background technology
In high-pressure casting industry, especially for tabular foundry goods, the increase inferior along with compression mod there will be casting deformation conventionally.After mould is produced a cover half time, there will be the phenomenon such as surface checking, the sticky aluminium of core, cause mould inhomogeneous mould power, thus distortion while causing foundry goods to eject.
Summary of the invention
The purpose of this utility model is that a kind of ejector apparatus that prevents casting deformation will be provided.
To achieve these goals, the technical solution of the utility model is: foundry goods liftout attachment, is made up of nut, connecting rod I, threeway flange, oil cylinder, connecting rod II, push rod push pedal, push rod fixed head, push rod, return push rod, mould.Nut is fixed on the lower end of threeway flange in the left side of connecting rod I; The upper end of threeway flange and the left side sliding connection of connecting rod II; The right side of connecting rod I and connecting rod II is all connected with push rod push pedal; The take-off lever of oil cylinder is connected with the middle part of threeway flange; Return push rod is fixed on the upper-lower position of push rod fixed head, and push rod is fixed between upper and lower return push rod; Push rod and return push rod all coordinate with mold-slide.
When actual use, there is gap A in the step place of threeway flange right side and connecting rod II, while making the demoulding, the push rod of below first contacts position large mould power with workpiece, move right after A until threeway flange, connecting rod I and connecting rod II apply uniform thrust to push rod simultaneously, by it from mold ejection.The size of described gap A is according to the size adjustment of casting deformation amount.
When the utility model in use can effectively prevent the demoulding of flat-type parts of Casting, produce distortion, there is the features such as technique advanced person, simple in structure, performance safety is stable simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of foundry goods liftout attachment.
In figure, 1-nut, 2-connecting rod I, 3-threeway flange, 4-oil cylinder, 5-connecting rod II, the push pedal of 6-push rod, 7-push rod fixed head, 8-push rod, 9-return push rod, 10-mould, 11-workpiece.
Detailed description of the invention
Describe details and the working condition according to the concrete device the utility model proposes in detail below in conjunction with accompanying drawing.
The utility model foundry goods liftout attachment, is made up of nut 1, connecting rod I 2, threeway flange 3, oil cylinder 4, connecting rod II 5, push rod push pedal 6, push rod fixed head 7, push rod 8, return push rod 9, mould 10.Nut 1 is fixed on the lower end of threeway flange 3 in the left side of connecting rod I 2; The upper end of threeway flange 3 and the 5 left side sliding connections of connecting rod II; The right side of connecting rod I 2 and connecting rod II 5 is all connected with push rod push pedal 6; The take-off lever of oil cylinder 4 is connected with the middle part of threeway flange 3; Return push rod 9 is fixed on the upper-lower position of push rod fixed head 7, and push rod 8 is fixed between upper and lower return push rod 9; Push rod 8 and return push rod 9 are all slidably matched with mould 10.
When actual use, there is gap A in the step place of threeway flange 3 right sides and connecting rod II 5, while making the demoulding, the push rod 8 of below first contacts position large mould power with workpiece, move right after A until threeway flange 3, connecting rod I 2 and connecting rod II 5 apply uniform thrust to push rod 8 simultaneously, and it is ejected from mould 10.The size of described gap A is according to the size adjustment of casting deformation amount.
