Abstract
The utility model relates to an extrude bow-shaped welding seam mould of formula plastics welder, including the rifle mouth of plastics welder, its characterized in that, the rifle mouth on cup joint perpendicularly and be fixed with bow-shaped welding seam mould, the mould comprises rectangle mould body and jackscrew, it has bow-shaped recess to open along the longitudinal center line at the upper surface of rectangle mould body, bow-shaped recess only runs through the terminal surface of rectangle mould body one end, it has the round hole that matches with the rifle mouth external diameter to open perpendicularly along the longitudinal center line at the lower surface of rectangle mould body, the round hole is close to the rectangle mould body other end, and communicate with bow-shaped recess, it has the jackscrew hole of internal thread to open perpendicularly to the axial of round hole in the side of rectangle mould body, the jackscrew hole communicates with each other with the round hole; the jackscrew is screwed into the jackscrew hole to tightly attach and fix the gun nozzle. The advantages are that: the mold is fixedly connected with the nozzle of the plastic welding gun by the jackscrew, so that a full, smooth and uniform arc-shaped welding line can be formed on the welding line, and the quality of plastic products is improved.
Description
Technical Field
The utility model belongs to the technical field of the plastic products welding, concretely relates to extrude bow-shaped welding seam mould of formula plastics welder is applicable to large-scale plastic sheet's hot-blast formula quick welding process.
Background
In plastic engineering, the welding of plastic products is widely carried out using an extrusion plastic welding torch. However, due to the prior art or human factors, the extrusion type plastic welding gun often has the phenomena of uneven, irregular, not smooth, suddenly high and suddenly low welding seams, insufficient cold solder, false solder and insufficient compactness in the plastic product welding process, and is difficult to meet the HG/T4281-2011 standard of the plastic product welding process procedure, thereby affecting the quality of the plastic product.
Disclosure of Invention
Problem to prior art existence, the utility model aims to provide an extrude formula plastics welder's bow-shaped welding seam mould is fixed through with this mould and extrusion formula plastics welder rifle mouth accordant connection, makes the welding seam can form a full glossy bow-shaped welding seam, improves plastic products's quality.
The utility model aims at realizing through the following technical scheme:
the utility model discloses an extrude bow-shaped welding seam mould of formula plastics welder, including extruding formula plastics welder's rifle mouth, its characterized in that the rifle mouth on cup joint perpendicularly and be fixed with bow-shaped welding seam mould, bow-shaped welding seam mould constitute by rectangle mould body and jackscrew the upper surface of rectangle mould body along the longitudinal center line open and to have bow-shaped recess, bow-shaped recess run through the terminal surface of rectangle mould body one end, vertically open the round hole that matches with the rifle mouth external diameter on the lower surface of rectangle mould body along the longitudinal center line, the round hole is close to the rectangle mould body other end, and with the communication of bow-shaped recess, open the jackscrew hole of taking the internal thread perpendicular to the axial of round hole in the side of rectangle mould body, the jackscrew hole communicates with each other with the round hole; the jackscrew is screwed into the jackscrew hole and is tightly attached and fixed with the gun nozzle.
The arch shape has the following parameter ranges: the height of the arch is 4 mm-6 mm; the chord length of the arch is 10 mm-15 mm; the radius of the arch is 20 mm-25 mm.
Compared with the prior art, the utility model has the advantages that:
because the utility model discloses cup joint perpendicularly on the rifle mouth and be fixed with bow-shaped welding seam mould, the setting of the bow-shaped recess on bow-shaped welding seam mould upper portion, the welding seam is full smooth even bow-shaped welding seam, has satisfied the HG/T4281-2011 standard of plastic products welding process regulation, and work efficiency and welding quality obtain improving greatly, and work efficiency and welding quality obtain very big improvement.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a view taken along direction a of fig. 1.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, the arcuate welding line mold of the extrusion plastic welding gun of the present invention comprises a gun nozzle 1 of the extrusion plastic welding gun, and is characterized in that the gun nozzle 1 is vertically sleeved and fixed with an arcuate welding line mold, the arcuate welding line mold is composed of a rectangular mold body 2 and a jackscrew 3, the rectangular mold body 2 is made of polytetrafluoroethylene, and has a length of 60 mm, a width of 30 mm and a height of 20 mm; an arch-shaped groove 2-1 is formed in the upper surface of the rectangular die body 2 along the longitudinal center line, the arch-shaped groove 2-1 penetrates through the end face of one end of the rectangular die body 2, the arch height is 5 mm, the arch chord length is 15 mm, and the arch radius is 25 mm, so that an arc die cavity is formed; a round hole 2-2 matched with the outer diameter of a gun nozzle is vertically formed in the lower surface of the rectangular mould body 2 along the longitudinal central line, the diameter of the round hole is 12 mm, the round hole 2-2 is close to the other end of the rectangular mould body 2 and is communicated with the arc-shaped groove 2-1, a jackscrew hole 2-3 with internal threads is formed in the side surface of the rectangular mould body 2, which is perpendicular to the axial direction of the round hole 2-2, and the jackscrew hole 2-3 is communicated with the round hole 2-2; the jackscrew 3 is screwed into the jackscrew hole 2-3 and tightly attached and fixed with the gun nozzle 1, and the jackscrew 3 is an M5 bolt.
The utility model discloses a welding process:
when welding plastic plates, especially thicker plastic plates, firstly placing plastic welding rods into an extrusion type plastic welding gun nozzle 1, then fixing the utility model on the position of the nozzle 1 by using jackscrews 3 positioned on the side surface, wherein the plastic welding rods enter an arc mold cavity which corresponds to a welding port of the welded plastic plates; then begin to weld, if and only when the plastics raw materials that extrude reach the saturation state after in the circular arc die cavity, just will the utility model discloses an arch-shaped welding seam mould is along welding mouthful department at the uniform velocity walking, forms a full arch-shaped welding seam at last, accomplishes welding work.
During welding, if proper pressure is applied to the weld surface, the weld material will transition from elastic to plastic, which may also promote molecular interdiffusion and squeeze out residual air in the weld, thereby increasing the weld face sealing performance.
