Abstract
The utility model discloses a special-shaped die capable of realizing expansion of a calibre of a thin-wall purely plastic tube, mainly solving the problems that the existing plastic pipeline shaping die needs to be strictly matched with an extruder in specifications so as to cause bad adaptability and low utilization rate of equipment. The special-shaped die is characterized in that more than two arc-shaped bulges are uniformly distributed on the outer surface of the shaping die (1); and one end, which is connected with the shaping die (1), of a sizing die (2) is a conical surface. The special-shaped die is used for realizing production of the large-calibre thin-wall purely plastic tube by virtue of small equipment under the condition that the maximum outer diameter of the die is not changed, thus improving the adaptability and the utilization rate of the equipment.
Description
Technical field
The utility model relates to technical field of plastic, a kind ofly specifically can realize that thin-walled is pure and moulds the special mouth mould that the tubing bore enlarges.
Background technology
The basic production mode of plastic conduit is at present: the plastics dedicated extruder provides plastifying material and by the moulding of typing die extrusion, realizes the final shaping of tubing under the effect of plug die.Realize that need to finalize the design specification and the extruder specification of mouthful mould of this mode of production strictly mate, and be subjected to the restriction of mounting condition and the device space, if the tubing bore has large variation just to be difficult to realize, apparatus adaptability is poor, utilization rate is low thereby make.
Summary of the invention
Need to make the deficiency that apparatus adaptability is poor, utilization rate is low with the strict coupling of extruder specification in order to overcome existing plastic conduit typing mouthful mould, the utility model provides a kind of can realize the pure special mouth mould of moulding the expansion of tubing bore of thin-walled, this special mouth mould is not in the situation that change a mouthful mould maximum outside diameter, realization is produced the large-caliber thin-walled pure pipe of moulding with skinny device, has improved adaptability and the utilization rate of equipment.
The technical solution of the utility model is: a kind ofly can realize that thin-walled is pure and mould the special mouth mould that the tubing bore enlarges, comprise typing mouthful mould and sizing mouth mould, a typing mouthful mould is connected with sizing mouth mould, the outer surface of described typing mouthful mould is evenly equipped with the arc-shaped convex more than 2, and an end that links to each other with typing mouthful mould of described sizing mouth mould is the conical surface.
The utlity model has following beneficial effect: owing to taking such scheme, the outer surface of typing mouthful mould is evenly equipped with several arc-shaped convex, making the cross sectional shape of typing mouthful mould is the S shape of circumferencial direction, like this in the situation that do not change typing mouthful mould maximum outside diameter, increase its perimeter length, the tube end face girth of outlet mold can be lengthened, match with sizing mouth mould, the expansion for the tubing bore provides condition under the pure prerequisite of moulding thickness of pipe wall of thin-walled not changing, realized producing the large-caliber thin-walled pure pipe of moulding with skinny device, improved adaptability and the utilization rate of equipment.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is right view of the present utility model.
1-typing mouthful mould among the figure, 2-sizing mouth mould.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Figure 1 and Figure 2, a kind ofly can realize that thin-walled is pure and mould the special mouth mould that the tubing bore enlarges, comprise typing mouthful mould 1 and sizing mouth mould 2, a typing mouthful mould 1 is connected with sizing mouth mould 2, the outer surface of described typing mouthful mould 1 is evenly equipped with the arc-shaped convex more than 2, projection and groove equal and opposite in direction and evenly distribution, as preferentially, projection is 5-6, jointly form petal-shaped with groove, in the situation that do not change the perimeter of section that typing mouthful mould 1 maximum outside diameter has increased mouthful mould, make its discharging end face sectional area larger like this, the expansion for the tubing bore under the prerequisite that does not change the pure wall thickness of moulding pipe of thin-walled provides condition.An end that links to each other with typing mouthful mould 1 of described sizing mouth mould 2 is the conical surface, and the external diameter of conical surface smallest end is slightly less than typing mouthful mould 1 minimum diameter, pass through sizing mouth mould 2 by typing mouthful mould 1 tubing out like this after, realized the expansion of tubing bore.
This special mouth mould has realized that the pure tubing bore of moulding of thin-walled enlarges in the situation that do not change a typing mouthful mould maximum outside diameter, makes mini-plant just can produce the large-caliber thin-walled pure pipe of moulding, and improves the utilization rate of equipment, and realizes continuously production.
Claims (1)
1. can realize the pure special mouth mould of moulding the expansion of tubing bore of thin-walled for one kind, comprise typing mouthful mould (1) and sizing mouth mould (2), a typing mouthful mould (1) is connected with sizing mouth mould (2), it is characterized in that: the outer surface of described typing mouthful mould (1) is evenly equipped with the arc-shaped convex more than 2, and an end that links to each other with typing mouth mould (1) of described sizing mouth mould (2) is the conical surface.
