Abstract

The utility model discloses a hot runner cooling device, which comprises a cooling sleeve installed on a hot nozzle, wherein the hot nozzle and the cooling sleeve are arranged in a lower die core, a pipeline is connected to the cooling sleeve, and cooling water is filled in the pipeline. According to the utility model, by utilizing better heat conduction coefficient of the cooling sleeve to transfer heat and by utilizing cooling water to control temperature at the same time, the temperature of the hot nozzle is enabled to be kept within a certain range, so as to avoid partial high temperature of a sprue opening.

Description

The hot flow path cooling device
Technical field
The utility model relates to a kind of hot flow path cooling device, belongs to plastic mould and makes the field.
Background technology
Plastic mould has into adhesive dispenser, and is very high because advancing the adhesive dispenser temperature, especially advances to water in the device at hot flow path.Because high temperature, heat is chewed very high that temperature can become, cause cast gate position localized hyperthermia, because the inequality of temperature, be easy to produce defective in the sizing material forming process, such as some local shrinkage cavities, shrinkage porosite and stress are concentrated, and the heat transfer coefficient of steel is higher, thereby cause whole mold temperature to raise, this not only has higher requirement to the die steel performance, and also is disadvantageous to plastic parts moulding, certainly the temperature height more is conducive to the flowability of plastic cement, but consider, should control according to the best forming temperature of plastics the temperature of whole mould, crystalline forming under so favourable temperature, thereby obtain more refinement of crystal grain, the better product of comprehensive mechanical property.No matter consider from cost or product quality, it is to have a very big significance that mold temperature is controlled at certain scope, on the market of now, do not obtaining enough attention aspect the hot flow path cooling, there is not relevant standard yet, general all is to determine according to on-the-spot master worker's experience, and this will cause the not trackability of a lot of problems.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is, a kind of hot flow path cooling device is provided, and to chew temperature unsuitable too high to control heat, and guaranteeing can localized hyperthermia into cast gate, prolongs die life, improves the quality of products.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hot flow path cooling device, it is characterized in that: comprise being installed in the coolant jacket that heat is chewed, described heat is chewed with coolant jacket and is located in the lower die, be connected with pipeline on the described coolant jacket, pass into cooling water in the described pipeline.
Aforesaid hot flow path cooling device is characterized in that: described pipeline is annulus line.
Aforesaid hot flow path cooling device is characterized in that: described annulus line includes the mouth of a river and delivery port.
Aforesaid hot flow path cooling device is characterized in that: the material of described coolant jacket is copper.
The beneficial effects of the utility model are: utilize coolant jacket preferably the coefficient of heat conduction conduct heat, utilize simultaneously cooling water to control temperature, the temperature that heat is chewed remains on certain scope, thereby avoids cast gate localized hyperthermia.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
For further disclosing the technical solution of the utility model, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: as depicted in figs. 1 and 2, a kind of hot flow path cooling device comprises that being installed in heat chews coolant jacket 2 on 1, the material of coolant jacket 2 is preferably material of heat transfer property, such as copper.Heat chew 1 and coolant jacket 2 be located in the lower die 3.Heat is chewed 1 by heat and is delivered on the coolant jacket 2, is connected with annulus line 6 on the coolant jacket 2, and annulus line 6 includes the mouth of a river 4 and delivery port 5, passes into cooling water in the pipeline, and heat is pulled away under the effect of cooling water channel, and heat is chewed 1 temperature and decreased.By regulating the temperature of cooling water, control heat and chew 1 temperature, make heat chew 1 temperature and remain on certain scope, thereby avoid cast gate localized hyperthermia.
More than by description of listed embodiment, basic conception of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on the technical solution of the utility model all should belong to protection domain of the present utility model.
