Description

Square plastic-steel window splicing pipe forming die

Technical Field

The utility model belongs to the technical field of extrusion moulding mould technique and specifically relates to a square steel window of moulding piece together a tub forming die.

Background

The plastic-steel doors and windows often involve some places to strengthen the strength of the plastic-steel doors and windows by using splicing pipes, the splicing pipe sectional materials on the plastic-steel doors and windows are generally square structures with hollow interiors, the structural strength of the sectional materials is high, and meanwhile, forming frames are arranged on four corners of the sectional materials so as to facilitate other structural connection.

Disclosure of Invention

The utility model aims at providing a square steel window of moulding piece together a tub forming die to above-mentioned condition, this mould is through making the improvement to the runner in the mould, has effectively promoted the speed of benefit position that the inside material of mould flows, and it is obvious to the shaping quality promotion effect of product.

The utility model has the following concrete scheme: a square plastic-steel window pipe splicing forming die sequentially comprises a first opening die, a second opening die, a confluence plate, a first support, a second support and a die body, pipe splicing forming cavities are formed in the first opening die and the second opening die, a confluence channel is arranged in the confluence plate, transition channels are arranged in the first support and the second support, a flat conical inlet is formed in the inlet of the die body along the central axis, the width of the upper end and the lower end of the flat conical inlet is smaller than that of the left end and the right end, and the front part of the flat conical inlet is large in caliber and the tail part of the flat conical inlet is; and a square conical flow guide channel is also arranged in the die body close to the tail part of the flat conical inlet, the diameter of the front end port of the square conical flow guide channel is small, the diameter of the tail end of the square conical flow guide channel is large, the front end and the tail end of the square conical flow guide channel are both of flat rectangular structures, and the tail end of the square conical flow guide channel is communicated with a transition channel in the second bracket.

Furthermore, in the present invention, the inclined conical surface of the square conical diversion channel and the included angle corresponding to the central axis are 9.55 °.

Furthermore, in the present invention, the included angle between the upper and lower conical surfaces of the flat conical inlet is 60 °.

The utility model discloses a set up the flat cone entry for the material stream pressure boost speed-up that gets into, the melting material just can fast fill the position like this, then passes through the square cone water conservancy diversion passageway release material stream at the back again, because square cone water conservancy diversion passageway is the rectangle cross-section passageway that expandes to both sides, fine material stream trend in having accorded with the back die cavity makes the material stream evenly extend to both sides, is favorable to promoting the shaping quality of piecing together the pipe section bar.

Detailed Description

Referring to fig. 2-6, the utility model relates to a square plastic-steel window splicing pipe forming die, which comprises a first opening die 1, a second opening die 2, a confluence plate 3, a first support 4, a second support 5 and a die body 6 in sequence, wherein a splicing pipe forming cavity is arranged in the first opening die and the second opening die, a confluence channel is arranged in the confluence plate, a transition channel 9 is arranged in the first support and the second support, a flat cone inlet 8 is arranged at the inlet of the die body along the central axis, the widths of the upper end and the lower end of the flat cone inlet are smaller than those of the left end and the right end, and the front caliber and the tail caliber of the flat cone inlet are small; and a square conical flow guide channel 7 is also arranged in the die body close to the tail part of the flat conical inlet, the diameter of the front end port of the square conical flow guide channel is small, the diameter of the tail end of the square conical flow guide channel is large, the front end and the tail end of the square conical flow guide channel are both of flat rectangular structures, and the tail end of the square conical flow guide channel is communicated with a transition channel in the second bracket.

Further, in this embodiment, an included angle between the inclined conical surface of the square conical diversion channel 7 and the corresponding central axis is 9.55 °.

Further, in this embodiment, the angle between the upper and lower tapered surfaces of the flat tapered inlet 8 is 60 °.

The material flow gets into from die body one end, the utility model discloses a set up the flat toper entry in die body entrance, make the material flow pressure boost speed-up that gets into like this, the melting material just can fast fill the position fast like this, then through the release material flow of the square toper water conservancy diversion passageway at back again, because the square toper water conservancy diversion passageway is the rectangle cross-section passageway of lying to the flat that both sides expand, fine having accorded with the material flow trend in the die cavity at the back for the material flow is to the even extension in both sides, is favorable to promoting the shaping quality of piecing together the pipe section bar.
