Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the sealing strip cooling tool in the prior art cannot rely on its own structure to fix the position of the shaping piece, which causes the sealing strip channel in the cooling tool to easily deviate from its position, affecting the cooling and shaping effect of the sealing strip

Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, a self-locking cooling sizing tooling of the present invention includes a sizing block 1. In this embodiment, the sizing block 1 is set to four pieces, which are respectively the first sizing block 5, the second sizing block The shaped block 6, the third shaped block 7, and the fourth shaped block 8, in other embodiments, multiple shaped blocks can be provided according to the different channels of the sealing strip to be formed. The four shaped blocks 1 are assembled to form each other. After the shaped blocks 1 are assembled and formed, there is a channel 2 inside that matches the profile of the sealing strip and is suitable for extrusion of the sealing strip. The bottommost shaped block 1 is fixed, and the two adjacent The contact surface between the shaped blocks 1 is a Z-shaped contact surface 3, the Z-shaped angle α of the Z-shaped contact surface 3 is an acute angle, and the vertical height of the Z-shaped contact surface...

Abstract

The invention relates to a cooling shaping tool, in particular to a self-locking cooling shaping tool for a sealing strip and belongs to the technical field of shaping of sealing strips. The self-locking cooling shaping tool comprises a plurality of shaping blocks (1), wherein after the shaping blocks (1) are assembled and formed, the shaping blocks are provided with a channel (2) matched with the molding surface of the sealing strip and suitable for extrusion shaping of the sealing strip; the shaping block at the bottom layer of the cooling shaping tool formed by assembling is fixed; the contact surface between two adjacent shaping blocks (1) is a Z-shaped contact surface (3); the Z-shaped included angle alpha of the Z-shaped contact surface (3) is an acute angle; and the Z-shaped contact surface (3) between two adjacent shaping blocks (1) is pressed tightly under the action of the impelling force for extrusion shaping of the sealing strip. The cooling shaping tool can realize the fastening self-locking function due to the Z-shaped contact surface structure, effectively avoids position loose of the cooling shaping tool during use, and overcomes the defects that the cooling shaping tool is not tight in positioning, easy to loosen and the like, which are caused by screw positioning.

Description

technical field [0001] The invention relates to a cooling and shaping tool, in particular to a self-locking sealing strip cooling and shaping tool, which belongs to the technical field of sealing strip shaping. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, seats, sunroof, engine box and trunk, etc. It has waterproof, sealing, sound insulation, dustproof, antifreeze, shock absorption, It plays an important role in keeping warm and saving energy. It must have strong tensile strength, good elasticity, and good temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structure size of the rubber strip must match the profile. When producing sealing strips, the extruded strips are in a very soft state when they are extruded by the extruder, and must go through other processes such as shaping before they ca...
