Description
Technical Field
The utility model belongs to the technical field of machining, concretely relates to sleeve ejector pin device.
Background
In the development process of automobile spare and accessory parts products, due to the casting manufacturability requirement, some processing hole sites are precast to improve the casting quality of the products when casting is needed, but the ejection position of the products is limited when the precast is carried out by adopting a precast pin, and a common ejector rod cannot be used at the position of the precast pin, so that the ejection force is unbalanced when the products are opened, and the difficulty in opening the molds and the deformation of the products are easy to generate.
SUMMERY OF THE UTILITY MODEL
For remedying the not enough of prior art, the utility model provides a sleeve ejector pin device, the ejecting force is balanced, can eliminate the problem that mould die sinking difficulty and product die sinking warp.
The utility model discloses a realize through following technical scheme:
a sleeve ejector rod device comprises a sleeve ejector rod and a precast pin, wherein the sleeve ejector rod and the precast pin are concentric cylinders, and the diameter of the sleeve ejector rod is larger than that of the precast pin; the sleeve ejector rod is a cylinder with a hollow inner part, and the precast pin penetrates through the sleeve ejector rod with the hollow inner part; the length of the precast pin is greater than that of the sleeve ejector rod.
As a preferred scheme, the bottom of the sleeve ejector rod is fixed on an ejector rod connecting plate, and the ejector rod connecting plate is fixed on an ejector rod pressing plate.
According to the preferable scheme, the bottom of the precast pin penetrates through the sleeve ejector rod and is fixed on a precast pin connecting plate, and the precast pin connecting plate is fixed on a precast pin pressing plate; in the movement process, the precast pin connecting plate and the precast pin pressing plate are fixed, and the ejector rod pressing plate and the ejector rod connecting plate drive the sleeve ejector rod to perform ejection action, so that the aim of ejecting a mold opening product of the mold is fulfilled.
The utility model has the advantages that: compared with the prior art, the utility model discloses a sleeve ejector pin device can guarantee that the ejecting force is balanced, eliminates the problem that mould die sinking difficulty and product die sinking warp.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 sleeve ejector rod, 2 precast pin, 3 ejector rod connecting plates, 4 ejector rod pressing plates, 5 precast pin connecting plates and 6 precast pin pressing plates.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, so as to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply, and the protection scope of the present invention includes but is not limited to the following embodiments, and any modifications made to the details and forms of the technical solution of the present invention without departing from the spirit and scope of the present invention all fall into the protection scope of the present invention.
The attached drawing is a concrete implementation mode of the utility model. The device comprises a sleeve ejector rod 1 and a precast pin 2, wherein the sleeve ejector rod 1 and the precast pin 2 are concentric cylinders, and the diameter of the sleeve ejector rod 1 is larger than that of the precast pin 2; the sleeve ejector rod 1 is a cylinder with a hollow inner part, and the precast pin 2 penetrates through the sleeve ejector rod 1 with the hollow inner part; the length of the precast pin 2 is greater than that of the sleeve ejector rod 1; the bottom of the sleeve ejector rod 1 is fixed on an ejector rod connecting plate 3, and the ejector rod connecting plate 3 is fixed on an ejector rod pressing plate 4; the bottom of the precast pin 2 penetrates through the sleeve ejector rod 1 and is fixed on a precast pin connecting plate 5, and the precast pin connecting plate 5 is fixed on a precast pin pressing plate 6.
When the device is used specifically, a sleeve ejector rod 1, an ejector rod connecting plate 3 and an ejector rod pressing plate 4 are fixed, then a precast pin 2 penetrates through the sleeve ejector rod 1, and then the precast pin 2 is fixed through a precast pin connecting plate 5 and a precast pin pressing plate 6; in the motion process, the ejector rod connecting plate 3 and the ejector rod pressing plate 4 drive the sleeve ejector rod 1 to perform ejection action, and the pre-cast pin 2 is fixed, so that the purpose of ejecting a mold opening product is achieved, the ejection force can be guaranteed to be balanced in the operation, the mold opening is simple, and the product cannot deform during mold opening.
