Abstract
The invention discloses a hot runner structure which is applied to a die and comprises a hot runner arranged in the die, a cooling water jacket and a heat resisting sheet, wherein the front end of the hot runner is provided with a hot runner nozzle, the cooling water jacket is arranged at the outer edge of the front end of the hot runner, and the heat resisting sheet is arranged at the front end of the hot runner. The heat resisting sheet and the cooling water jacket are arranged between the hot runner and an insert or finished product, and heat conduction is effectively reduced, thus the hot runner structure prevents the finished product from generating punching marks to ensure that the finished product reaches the design requirement of a customer.
Description
[technical field]
The present invention relates to a kind of hot flow path structure, be specifically related to a kind of hot flow path structure that finished product dashes the material trace that reduces.
[background technology]
In finished product ejection formation field, the extensive use of hot flow path technology, the hot flow path technology not only can reduce the waste of plastic material, also promotes and produces yield, has reduced production cost.Along with requirement of client is increasingly high, now the client can require the common die face of the direct charging of hot flow path at finished product, like this waste material still less, and the appearance of finished product the charging vestige can not occur.
See also shown in Figure 1ly, it illustrates the sketch map of existing hot flow path structure.This hot flow path 10 is open hot flow path; These open hot flow path 10 front ends are provided with hot flow path mouth 11; Open hot flow path 10 direct chargings are at finished product 20 common die faces, and because of above-mentioned open hot flow path 10 temperature are very high, heat can be directly delivered on die and the finished product 20 in process of production; Cause the plastics appearance surfaces after the moulding material trace (claiming thermal blooming again) can occur dashing, can't reach client's designing requirement.
In view of this, in fact be necessary to develop a kind of hot flow path structure, this hot flow path structure during at the finished product common die face, has effectively reduced hot conduction in the direct charging of hot flow path, prevents that the material trace from appearring dashing in finished product, reaches client's designing requirement.
[summary of the invention]
Therefore, the purpose of this invention is to provide a kind of hot flow path structure, this hot flow path structure during at the finished product common die face, has effectively reduced hot conduction in the direct charging of hot flow path, prevents that the material trace from appearring dashing in finished product, reaches client's designing requirement.
In order to achieve the above object, hot flow path structure of the present invention is applied in the mould, and this hot flow path structure comprises:
One hot flow path, it is located in the above-mentioned mould, and the front end of this hot flow path is provided with the hot flow path mouth;
One cooling jacket, it is located at the outer rim of above-mentioned hot flow path front end;
One heat shield, it is located at above-mentioned hot flow path mouth front end, and the heat that this heat shield reduces hot flow path is sent on the above-mentioned cooling jacket.
Compared to prior art, hot flow path structure of the present invention is installed heat shield and cooling jacket between hot flow path and die or finished product, effectively reduced hot conduction, prevents that the material trace from appearring dashing in finished product, reaches client's designing requirement.

[specific embodiment]
See also shown in Figure 2ly, it illustrates the sketch map of hot flow path structure of the present invention.
Hot flow path structure of the present invention, it is applied in the mould, and this hot flow path structure comprises:
One hot flow path 100; This hot flow path 100 is needle valve hot flow path or open hot flow path; In present embodiment, this hot flow path 100 is open hot flow path, and this open hot flow path 100 is located in the above-mentioned mould; The front end of this open hot flow path 100 is provided with hot flow path mouth 110, and the front end temperature of this open hot flow path 100 is higher;
One cooling jacket 200, it is placed in the outer rim of above-mentioned open hot flow path 100 front ends, in this cooling jacket 200 normal-temperature water or frozen water is housed;
One heat shield 300, it is located at hot flow path mouth 110 front ends of above-mentioned open hot flow path 100, and the heat that this heat shield 300 is used to reduce open hot flow path 100 is sent to cooling jacket 200.
In present embodiment; Hot flow path structure of the present invention is installed heat shield 300 and cooling jacket 200 between open hot flow path 100 and finished product 400, the heat that reduces open hot flow path 100 through heat shield 300 is delivered on the cooling jacket 200, in cooling jacket 200, uses normal-temperature water or frozen water cooling simultaneously; Reduce cooling jacket 200 temperature; Reduce heat and be sent on die and the finished product 400, effectively reduced hot conduction, prevent to occur on the finished product 400 dashing the material trace.
Compare with prior art, hot flow path structure of the present invention during at the finished product common die face, has effectively reduced hot conduction in the direct charging of hot flow path, prevents that the material trace from appearring dashing in finished product, reaches client's designing requirement.
