Abstract
The utility model discloses a hot runner cooling device of a mould. The hot runner cooling device comprises a runner and a spray nozzle, wherein injection molding fluid passes through the runner, and the spray nozzle is arranged under the runner. A cooling water channel is arranged at the part of the outer wall of the runner close to the spray nozzle, a pipeline is connected onto the cooling water channel, and cooling water enters into the pipeline. The cooling water channel is arranged at the part of the outer wall of the runner close to the spray nozzle, and the cooling water enters into the pipeline to reduce the temperature of the runner, therefore the temperature of a gate position is reduced, and the quality of plastic products is increased.
Description
Technical field
The utility model relates to a kind of cooling device, particularly relates to a kind of mould hot runner cooling device.
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 runner.Because high temperature, it is very high that nozzle temperature can become, cause cast gate position localized hyperthermia, because the inequality of temperature is 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.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is, a kind of mould hot runner cooling device is provided, and reduces the temperature of Jiao Dao by cooling water channel is set, thereby improves the quality of plastic cement products.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mould hot runner cooling device, comprise injection moulding the liquid Jiao Dao that passes through and the nozzle of being located at below, glue road, it is characterized in that: the outer wall of described Jiao Dao is provided with a cooling water channel near the nozzle place, be connected with pipeline on the described cooling water channel, pass into cooling water in the described pipeline.
Aforesaid mould hot runner cooling device is characterized in that: the cross section of described cooling water channel is round, 2/3 round, semi-circular or 1/3 round.
Aforesaid mould hot runner cooling device, it is characterized in that: described pipeline comprises water inlet and delivery port.
The beneficial effects of the utility model are: the outer wall at Jiao Dao arranges cooling water channel near the nozzle place, passes into the temperature that cooling water reduces Jiao Dao, thereby reduces the temperature at cast gate position, improves the quality of plastic cement products.
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 shown in Figure 1, a kind of mould hot runner cooling device, comprise the glue road 1 that injection moulding liquid passes through and the nozzle 2 of being located at 1 below, glue road, the outer wall in described glue road 1 is provided with a cooling water channel 3 near nozzle 2 places, and the cross section of described cooling water channel 3 is round, 2/3 round, semi-circular or 1/3 round.As shown in Figure 2, be connected with pipeline 5 on the described cooling water channel 3, described pipeline 5 comprises water inlet 6 and delivery port 7, passes into cooling water in the described pipeline 5.
During use, plastic cement liquid injects die cavity 4 by glue road 1, and the outer wall in glue road 1 arranges cooling water channel 3 near nozzle 2 places, passes into the temperature that cooling water reduces glue road 1, thereby reduces the temperature at cast gate position, improves the quality of plastic cement products.
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.
Claims (3)
