Embodiment Construction

[0013] The specific embodiments of the present invention are described below with reference to the drawings.

[0014] Such as figure 1 Shown is the overall principle diagram of the invention, figure 2 It is a cross-sectional view of the core mold section, vacuum condenser and water tank of the present invention. It can be seen from the figure that the present invention includes an extruder 1, a die 2. The improvement lies in that the die 2 passes the extruded pipe 3 through After the vacuum condenser 4 is sprayed and cooled, it is immersed and cooled in the cooling water 52 entering the water tank 5, and the finished product is finished after cooling.

[0015] In the present invention, the vacuum cold gathering box 4 is composed of 15-40 nozzles 42 and a vacuum pump 43 installed on the box body 41. The length of the vacuum cold gathering box 4 is 60-80 cm, and the number of nozzles 42 is the largest. Good for 20-30;

[0016] In the present invention, the water tank 5 is composed...

Abstract

An apparatus and method for producing PPR pipes by use of novel core mould and vacuum cooling case features that the plastic extruder and its extruding head are used. The pipe extruded out by said extruding head is cooled in a vacuum cooling case with 15-40 nozzles and vacuumizing pump and them cooled in a cooling water pool.

Description

Technical field [0001] The invention relates to a forming or connecting device for pipe plastics with annular openings, in particular to equipment and processes for producing PPR pipes by adopting a novel core mold and a vacuum condenser. Background technique [0002] In the prior art, the core molds of the equipment for producing plastic pipes are all linear round bodies, and the cooling devices are all spray cooling devices with a length of 6 meters. This type of device is used to produce antibacterial PPR pipes, and the following problems may occur: 1. The cooling device must have sufficient length, because the longer the length, the more conducive to eliminating the bonding line in the shaping area and improving the compactness of the internal structure of the product, but it does not consume energy and takes up space; 2. There is not enough internal If the extrusion rate is too fast, the melt cannot be fully plasticized and uniform, resulting in an increase in the scrap rate...
