Abstract
The utility model discloses a die head suitable for a die of a high-calcium content profiled bar in a material. The die head is sequentially provided with a finish mold 1, a finish mold 2, a bus plate, a bracket plate 1, a bracket plate 2 and a mold body from top to bottom, wherein a runner is formed in the middle part of the die head; a die core is arranged inside the runner; a transition plate is additionally arranged between the bus plate and the bracket plate 1; a runner is arranged at the middle part of the transition plate; a runner of the bus plate and a runner of the bracket plate 1 are taper runners; and the runner of the transition plate and a runner of the bracket plate 2 are straight runners. The die head is convenient to adjust the material flow speed, stabilize the material and reduce the inner stress of the section bar by additionally arranging the transition plate and improving the runners; and any dead angle and flow velocity slowing part inside the runners can be prevented, so as to prevent the material from being overheated and decomposed. The turbulent flow is reduced by the sectional compression, so that rigid polyvinyl chloride (PVC-U) material flow forms stable flow as far as possible; the reduction of die swelling is facilitated; and weld marks caused by bracket feet on the bracket plates also can be effectively removed.
Description
Technical field
The utility model relates to extrusion die, especially a kind of die head that is applicable to the profile shapes mould of high calcium-containing amount in material.
Background technology
The profile shapes die head mainly includes mouthful mould one, mouthful mould two, cylinder manifold, supporting plate one, supporting plate two and die body at present, the middle part of die head has runner, be provided with core rod in runner, the runner of its supporting plate one and supporting plate two is straight shape, and the runner of cylinder manifold is taper (as Fig. 1), owing to only having cylinder manifold one layer compression, can cause material sharply to compress, in runner, meeting produces the dead angle, flow velocity is moderate, and material is crossed thermal decomposition, and a layer compression can not well solve the weld mark that stent foot brings.
Summary of the invention
The purpose of this utility model is improved above shortcoming exactly, provide and to prevent that material from sharply compressing, moderate without any dead angle and flow velocity in runner, avoid material to cross thermal decomposition, effectively eliminate a kind of die head that is applicable to the profile shapes mould of high calcium-containing amount in material of the weld mark that the stent foot on supporting plate brings.
Concrete scheme of the present utility model is a kind of die head that is applicable to the profile shapes mould of high calcium-containing amount in material, this die head from top to bottom discharges successively mouthful mould one, mouthful mould two, cylinder manifold, supporting plate one, supporting plate two and die body, the middle part of described die head has runner, be provided with core rod in runner, it is characterized in that: increasing between described cylinder manifold and supporting plate one has a rebound, the middle part of rebound has runner, the runner of the runner of described cylinder manifold and supporting plate one is tapered runner all, and the runner of rebound runner and supporting plate two all is straight runner.
The utility model is simple in structure, easy to use, by increasing the improvement of middle rebound and convection current road, be convenient to regulate the material Flow Velocity, stablize material, reduce the section bar internal stress, can prevent that runner is interior without any dead angle and the moderate part of flow velocity, thereby avoid material to cross thermal decomposition, the segmentation compression reduces turbulent flow, make PVC-U material stream form as much as possible steady flow, be conducive to reduce die swelling, can also effectively eliminate the weld mark that the stent foot on supporting plate brings.
