Abstract
The invention discloses structural improvement of a cold water jacket of a hot nozzle of a hot runner system, relates to the technical field of thermoplastic processing and particularly relates to the improvement of a cooling structure of a hot nozzle at the top end of a hot runner in a thermoplastic processing process. The improvement is realized by the following technical scheme: the improved structure comprises a hot runner, a cold water jacket and a hot nozzle, wherein the hot nozzle is fixed at the top end in the hot runner; the cold water jacket having a through hole shape is fixed at the top end in the hot runner; one end of the hot nozzle for discharging protrudes to a small-hole end of the cold water jacket; and a penetrating built-in waterway is arranged in the cold water jacket. The built-in waterway is processed by 3D printing. According to the structural improvement, the built-in waterway is processed into the cold water jacket, and the cooling waterway is close to the front end of a hot nozzle tip; when the cooling water is opened, the waterway passing through the cooling water can carry most of the heat at a nozzle tip sprue, and the temperature at the front end of the sprue can be effectively lowered, so that the phenomenon of sun spot yellowing on the product surface is fundamentally solved; and moreover, since 3D printing technology is adopted for internal water conveying, the impossibility in traditional processing is turned into reality.
Description
Technical field
The present invention relates to thermoplastic processing technical field, refer in particular to a kind of heat on the top of hot flow path during thermoplastic processing
The improvement of the cooling structure of nozzle.
Background technology
Hot flow path process technology is to ensure that runner and the plastics of cast gate are kept molten by carrying out by the method for heating
Injection., outside cold water jacket 2, as shown in accompanying drawing 1～2, hot flow path 1 is in a steady stream not for the front end cooling water channel 3 of the hot nozzle 4 of existing structure
To the hot nozzle in front end 4 is pushed the plastics of molten condition in disconnected ground, due to giving the cooling water channel 3 of hot nozzle 4 cooling outside cold water jacket 2,
Enter glue position apart from the hot nozzle in front end 4 farther out, cooling effect is not it is obvious that the jaundice of sun speckle in the product surface processing
Phenomenon, this phenomenon is embodied in the appearance surfaces of product, is not typically accepted by client, and this is also the skill in hot flow path industry simultaneously
An art difficult problem, so far industry class also well solve technical scheme.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point of the prior art, and provide a kind of heat of TOP-TIP
The structural improvement of the cold water jacket of nozzle.
The present invention is achieved through the following technical solutions：The structural improvement of the cold water jacket of hot nozzle of TOP-TIP, bag
Include hot flow path, cold water jacket and Re Zui, hot nozzle is fixedly arranged on the top in hot flow path, and the cold water jacket in through hole shape is fixedly arranged in hot flow path
Top, one end projection of hot nozzle discharging, in the small bore end of cold water jacket, is provided with the built-in water route of insertion inside cold water jacket.
Described built-in water route is processed by 3D printing.
The present invention goes due to being worked into built-in water route inside cold water jacket, and cooling water channel is before hot nozzle nozzle point
End, when cooling water is opened, water route through when can take away most of heat at nozzle point cast gate, before cast gate being effectively reduced
The temperature at end, makes the phenomenon that product surface sun speckle turns to be yellow obtain basic solution, and because this inside fortune water has used
3D printing technique, is even more very unlikely to become reality by processed in the past.
Brief description：
Accompanying drawing 1 is the cooling schematic diagram of existing cold water jacket；
Accompanying drawing 2 is the cooling schematic diagram of prior art；
Accompanying drawing 3 is the cooling schematic diagram of cold water jacket of the present invention；
Accompanying drawing 4 is the cooling schematic diagram of the present invention.
Specific embodiment：
See accompanying drawing 3～4, the structural improvement of the cold water jacket of hot nozzle of TOP-TIP, including hot flow path 1, cold water jacket 2 and hot nozzle 4,
Hot nozzle 4 is fixedly arranged on the top in hot flow path 1, and the cold water jacket 2 in through hole shape is fixedly arranged on the top in hot flow path 1, the discharging of hot nozzle 4
One end projection, in the small bore end of cold water jacket 2, is provided with the built-in water route 5 of insertion inside cold water jacket 2.
Described built-in water route 5 is processed by 3D printing.
When utilizing the present invention, hot flow path 1 continuously pushes the plastics of molten condition to the hot nozzle in front end 4, due to inciting somebody to action
Built-in water route 5 has been worked into be gone inside cold water jacket 2, built-in water route 5 near the front end of hot nozzle 4 nozzle point, when cooling water is opened,
The water in built-in water route 5 through when can take away most of heat at hot nozzle 4 nozzle point cast gate, cast gate front end can be effectively reduced
Temperature, make product surface sun speckle turn to be yellow phenomenon obtained basic solution.
Claims (2)
1. the structural improvement of the cold water jacket of hot nozzle of TOP-TIP, including hot flow path, cold water jacket and Re Zui, hot nozzle is fixedly arranged on heat
