Description
Technical Field
The utility model belongs to the technical field of extrusion tooling and specifically relates to a water tank that has an arch face for single armed plastics profile shapes.
Background
Plastic profile extrusion molding is a continuous process of extruding a molten parison from a die head, cooling and solidifying the molten parison through a shaping die and a water tank block. The shaping mould only makes the outer wall of the section material cool and harden to about 1/2, the cooling of the outer wall and the cooling of the whole section material and the deformation of the section material caused by the diffusion of the heat of the section material from the inside and the outside are all completed by the shaping blocks which are dense within the front 400mm or the front 800mm of the water tank inlet, so the shape of the section material can be adjusted in the area if the shape of the section material needs to be slightly changed.
With the continuous abundance of the types of the sections of the plastic profiles, the sections of the single-arm profiles are more and more complex (as shown in fig. 1), which brings unprecedented challenges to design and debugging. The profile has large size, thick arms, uneven arm thickness, increased claw openings and the like, and is difficult to ensure in design. After debugging, some problems can occur, particularly, the conditions of concave surface and convex surface of a single-arm section with larger size are easy to occur. In order to correct the problems of the front concave surface and the front convex surface, a series of other problems such as uneven arm thickness or uneven surface of the section can occur after the die is repaired, and the die is irreparably damaged at the moment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the existing section bar is difficult to adjust when the surface is concave and convex.
The utility model adopts the technical proposal that: the water tank with the arch surface for the single-arm plastic profile comprises a shaping block, a shaping die and a reverse strain shaping block, the reverse strain shaping block comprises an upper shaping block, a lower shaping block, a connecting screw, a positioning square key and a positioning square key screw, the upper shaping block is connected with the two sides of the lower shaping block through connecting screws, the positioning square key is arranged on the lower shaping block close to the connecting screws, the positioning square key screws penetrate through the positioning square key to be connected with the upper shaping block, a gap is left between the upper shaping block and the lower shaping block to form a cavity for the section bar to pass through, the lower surface of the upper shaping block protrudes towards the lower shaping block to form an arch surface of the upper shaping block, the lower surface of the lower shaping block protrudes to form a lower shaping block arch surface, the protruding direction of the lower surface of the lower shaping block is the same as that of the lower surface of the upper shaping block, and steps are arranged on two sides of the lower shaping block arch surface.
The utility model has the advantages that: after the structure is adopted, the shaping blocks with reverse strain are installed in the range of 200-400mm of the water tank inlet, the size of a cavity of each reverse strain shaping block is opposite to the deformation direction of the section, and a proper number of reverse strain shaping blocks are arranged according to the size of deformation, so that the strain distance of the section can be adjusted as required to correct the deformation of the section, the adjustment of a die head and shaping is avoided, the problems of large concave surface and large convex surface are simply, quickly and effectively solved, the debugging is facilitated, the large-surface flatness of the section is well maintained, the shape and the size required by the section can be achieved, and the physical performance of the section is not influenced.
