Problems solved by technology
However, since the metal flow rate is not uniform, and the profile width is close to the profile outlet width of the die pad, when the profile is extruded from the die hole, it is easy to appear left or right, and it is different from the narrow surface of the die pad outlet width direction. Comparing each other will eventually cause the profile to be twisted and unable to be extruded, which will affect the forming of the profile

Embodiment Construction
[0015] The core of this specific embodiment is to provide an assembly method of the die pad, which can avoid the phenomenon of deformation of the ultra-wide profile during extrusion, and solve the current problem in this field.
[0016] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to be essential to the solutions of the invention described in the claims.
[0017] The assembly method of the mold cushion provided in this specific embodiment, the assembly method of the mold cushion is used for the assembly of tools and molds during extrusion, please refer to figure 1 ; And the die pad is assembled before the wide expansion die. The above-mentioned assembly method, firstly, the profile after being formed by the widening die and the ...

The invention discloses a mold cushion assembling mode and a mold. The mold cushion assembling mode is used for assembling a tool and the mold in the extruding process. A mold cushion is assembled infront of a broadsiding mold. According to the mold cushion assembling mode, firstly, a profile molded through the broadsiding mold and the mold can be directly delivered out of a ring without passingthe mold cushion, wherein due to the fact that a rectangular hole of the ring is larger than an outlet of the mold cushion and the distance the profile moves by is shortened, the possibility that themold cushion is obstructed is lowered, and the through capacity is greatly increased; secondly, the mold cushion is located in front of the broadsiding mold, the mold cushion is stressed in the firstplace when being extruded, the borne force exceeds the stress of an original position, and the broadsiding mold and the mold are prevented from being directly subjected to the extruding force, so thatthe protection capacity is increased; and thirdly, the mold cushion can play a role as a flow guiding mold, metal flow uniformity is improved, and the extruding quality of the profile is improved. Bymeans of the mold cushion assembling mode, the phenomenon that the superwide profile deforms in the extruding process can be avoided, and problems in the field at the stage are solved.
Description
technical field [0001] The invention relates to the field of extruded profiles, and more specifically relates to an assembly method of a mold pad and a mold. Background technique [0002] During extrusion, the widening die and mold mainly play the role of forming, and the die pad and ring play the role of strengthening the strength of the widening die and the mold, so that the widening die and the mold do not deform during extrusion. They are mainly used for To produce flat and wide profiles, therefore, the mold pads and rings are provided with rectangular holes for the passage of profiles. In order to facilitate the passage of profiles, the outer dimension of the die pad hole is usually larger than the hole of the mold, and the outer dimension of the ring hole is larger than the hole of the die pad; however, the rectangular hole opened on the die pad and the ring cannot be too large, because if it is too large, the The effect of protecting the strength of the stretching di...
