[0026] By adopting the above-mentioned technical scheme, it plays the role of cooling the cooling water, so that the temperature of the water is rapidly reduced, and then enters the water tank 10 for circulating work, which reduces the temperature of the water and avoids the influence of the rise of the water temperature due to long-term work on the absorption of the mould. heat, which shortens the product molding time and improves work efficiency.

[0027] Preferably, both the air inlet 135 and the air outlet 136 are provided with a dust-proof net 139 , and the dust-proof net 139 is fixed on the side wall of the installation box 11 .

[0028] By adopting the above-mentioned technical scheme, the setting of the dust-proof net 139 prevents external dust, solid particles and other impurities from entering the heat dissipation box 131 in the heat dissipation chamber 134 with the air inlet 135 and the air outlet 136, which affects the heat dissipation of the heat dissipation box 131 and plays a role in filtering. ,Protective effects.

[0029] Preferably, several cooling fins 132 are evenly arranged on both sides of the cooling box 131, and the cooling fins 132 are arranged in a wave shape.

[0030] By adopting the above technical solution, the heat dissipation fins 132 are arranged in a wave shape, so that the heat dissipation area of ​​the heat dissipation fins 132 with the same length is increased, and the heat dissipation efficiency is improved.

[0031] Preferably, a box door 14 is hinged on one side of the installation box 11 , and a handle 15 is fixed on the end of the box door 14 away from the hinge.

[0032] By adopting the above technical scheme, it is convenient to open the box door 14 through the handle 15 by hand, and then add water to the water tank 10 in the installation box 11, which is convenient for work.

[0033] Preferably, the water tank 10 is provided with a liquid filling port 16 at the upper end of one side close to the tank door 14 , and a plug 17 is screwed on the liquid filling port 16 .

[0034] By adopting the above-mentioned technical scheme, the setting of the filling port 16 facilitates adding water into the water tank 10, and the setting of the plug 17 blocks the filling port 16 to prevent water from overflowing from the filling port 16 and play a sealing role.

[0035] Preferably, a knob 18 is fixed on the plug 17 .

[0036] By adopting the above-mentioned technical scheme, the setting of the knob 18 is convenient to turn the plug 17 by hand through the knob 18, so as to realize the opening and closing of the plug 17, which is convenient for work.

[0037] Preferably, an observation window 19 is provided on the side wall of the water tank 10 near the liquid filling port 16 .

[0038] By adopting the above-mentioned technical scheme, the setting of the observation window 19 is convenient for observing the amount of water in the water tank 10, so as to add it in time and facilitate the work.

[0039]Working principle: the mobile worktable 3 on the injection molding machine moves forward, and then the movable mold base 1 moves forward with the movable worktable 3 until the convex mold insert 5 on the movable mold base 1 is inserted into the concave hole in the static mold base 2 mold insert 6 to achieve mold closing, and then the injection molding machine injects liquid material into the mold cavity formed by the punch insert 5 and the die insert 6, and the water pump 9 is started at the same time as the material is injected, and then the water pump 9 turns the water tank 10 The water inside is transported through the liquid inlet pipe 8 to the heat-absorbing pipe 7 wound outside the die insert 6, the flowing water continuously absorbs the heat around the mold, and then the temperature of the mold and the material in the cavity is lowered, and the material is cooled to realize molding ;

[0040] The water that has absorbed the heat flows into the cooling tank 131 from the heat-absorbing pipe 7 by the liquid outlet pipe 12, and then flows into the cooling fins 132. 138 starts, and then generates wind force, and the wind blows the heat in the heat dissipation chamber 134 out of the heat dissipation chamber 134 through the air outlet 136, and then realizes the cooling and heat dissipation of the water. Realize the circulation of cooling water.

[0041] Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still It is possible to modify the technical solutions recorded in the foregoing embodiments, or to perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present invention shall be included in the within the protection scope of the present invention.
