Description

Technical Field

[0001] The utility model relates to the technical field of moulds, in particular to a separating device for an aluminum profile extrusion mould. Background Art

[0002] An aluminum profile extrusion mould is a tool for producing aluminum profiles. Extrusion is a commonly used aluminum profile processing method. After heating an aluminum ingot to a certain temperature, it is extruded into aluminum profiles with various cross-sectional shapes by an extruder.

[0003] In the invention patent application with the publication number of CN113680843A, it discloses an aluminum profile extrusion mould, including a bracket, an extrusion mechanism, a cutting mechanism and a forming mechanism. A support plate is connected to the bottom of the bracket. A rotating part with a guiding function is arranged inside the forming mechanism, and a drainage receiving part with a refrigerating function is arranged inside the rotating part.

[0004] The existing aluminum profile extrusion moulds generally use hydraulic cylinders or other driving mechanisms for mould closing and separating, and generally are equipped with guiding components. However, due to the frequent mould closing and separating of the moulds, the guiding components are prone to wear, resulting in blockage when the moulds are closed and separated. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that the guiding components are prone to blockage when the moulds are closed and separated in the prior art, and to provide a separating device for an aluminum profile extrusion mould.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A separating device for an aluminum profile extrusion mould, including a base. The middle part of the upper end of the base is fixedly connected with a lower mould. Four corners of the upper end of the base are fixedly connected with columns. The tops of the four columns are jointly fixedly connected with a top plate. A hydraulic cylinder is fixedly installed on the upper end of the top plate. The output shaft of the hydraulic cylinder penetrates through the top plate and is slidably connected with the top plate. The end of the output shaft is fixedly connected with an upper mould. The upper mould abuts against the lower mould. Connecting blocks are fixedly connected to both the front and rear sides of the upper mould. A linkage column is fixedly connected to the surface of the connecting block. Guide sleeves are fixedly connected to both ends of the linkage column. The guide sleeves are slidably connected to the outer sides of the columns. A cavity is formed inside the linkage column. A sliding plate and a sponge block are slidably connected to the inner side of the cavity, and the sliding plate and the sponge block are in contact with each other.

[0008] In addition, the preferred structure is that a top pin is fixedly connected to the upper end of the sliding plate. The top pin penetrates through the linkage column and is slidably connected with the linkage column. A top seat is fixedly connected to the lower end edge of the top plate and above the top pin. Through the setting of the top seat, it has the effect of exerting a reaction force on the top pin.

[0009] In addition, a preferred structure is that a guide rod is fixedly connected to the inner side of the cavity. The guide rod penetrates through the sliding plate and is slidably connected to the sliding plate, and a spring is sleeved outside the rod body of the guide rod. Through the arrangement of the guide rod, it has a guiding effect when the sliding plate is lifted or lowered under force.

[0010] In addition, a preferred structure is that one end of the spring is fixedly connected to the sliding plate, and the other end of the spring is fixedly connected to the inner surface of the cavity. Through the arrangement of the spring, it has an auxiliary resetting effect on the sliding plate.

[0011] In addition, a preferred structure is that an oil outlet hole is formed inside the guide sleeve, and the oil outlet hole communicates with the cavity. Through the arrangement of the oil outlet hole, it is convenient for the lubricating oil to overflow from the guide sleeve.

[0012] In addition, a preferred structure is that a rubber plug is slidably connected inside the upper end of the linkage column, and a pull ring is fixedly connected to the upper end of the rubber plug. Removing the rubber plug is convenient for adding lubricating oil into the cavity.

[0013] The beneficial effects of the present utility model are as follows: By arranging a linkage column with guide sleeves at both ends on the upper die of the mold, the guide sleeves are sleeved outside the column, and a sponge block is arranged inside the linkage column for storing lubricating oil. When the hydraulic cylinder drives the upper die to separate from the lower die, the top pin is pressed downward by the reaction force from the top seat on the sliding plate, and the sliding plate squeezes the sponge block and releases the lubricating oil, thereby lubricating between the guide sleeve and the column, so that the mold separates smoothly.
