The injection molding machine is characterized in that an injection molding function is realized, before injection molding, a movable die 4 is driven to be matched with a fixed die 3, plastic raw material particles are fed into an injection molding mechanism 2, the plastic raw material particles are conveyed and heated into fluid to be injected into a cavity 5 from a discharge hole, after injection is finished, after plastic in the cavity 5 is cooled and molded stably, the movable die 4 and the fixed die 3 are driven to be separated, and a finished product is obtained.
The above belongs to the basic functions of the conventional injection molding device, and is not repeated, the key point of this embodiment is that, in order to improve the cooling uniformity of the injection molding device to the cavity 5, improve the cooling speed and the cooling effect, a cooling mechanism is specifically designed, specifically, as shown in fig. 2 and 3, a cooling mechanism for cooling the cavity 5 is arranged in the fixed mold 3, the cooling mechanism includes equal heat conducting grooves 6, heat radiating grooves 7 and heat exchange pieces 8, multiple groups of heat conducting grooves 6 are uniformly distributed in the fixed mold 3 along the outer side of the cavity 5, the heat radiating grooves 7 are one-to-one arranged on one side of the heat conducting grooves 6 away from the cavity 5, the heat exchange pieces 8 include heat conducting parts 9 and heat radiating parts 10, the heat conducting parts 9 are one-to-one arranged in the heat conducting grooves 6, a plurality of heat conducting fins 11 are uniformly distributed on the outer side of the heat conducting parts 9, a plurality of heat conducting mediums 12 are filled in the heat conducting grooves 6, the heat radiating parts 10 are one-to-one arranged in the heat radiating grooves 7, a plurality of heat radiating fins 13 are arranged on the outer side of the heat radiating parts 10, and two ends of the heat radiating grooves 7 are respectively provided with cooling medium inlets 14 and cooling medium outlets 15.
After the fluid plastic is injected into the cavity 5, the fluid plastic in the cavity 5 needs to be cooled and formed stably, then the mold is opened, and the natural cooling speed is too slow, so various cooling devices for cooling the cavity 5 are developed, but most of the cooling devices at present have the problems of insufficient cooling uniformity or further improved cooling uniformity, so the embodiment particularly designs the cooling mechanism for cooling the cavity 5. When cooling is required, a cooling medium, such as cooling water or other suitable medium, is fed into the heat sink 7 through the cooling medium inlet 14 and flows out from the cooling medium outlet 15. The heat in the cavity 5 is firstly conducted to the heat conducting part 9 in the heat conducting groove 6 and the heat conducting fins 11 on the heat conducting part 9 through the heat conducting medium 12, and then conducted to the heat radiating part 10 in the heat radiating groove 7 and the heat radiating fins 13 on the heat radiating part 10 through the middle part of the heat exchanging piece 8, and the cooling medium flowing in the heat radiating groove 7 takes away part of the heat in the heat radiating part 10 and the heat radiating fins 13 on the heat radiating part 10, so that the heat radiation and the cooling of the cavity 5 are realized. In this embodiment, the cooling medium does not directly or indirectly contact with the cavity 5, so as to prevent the medium from flowing into or penetrating into the cavity 5, avoid affecting the product molding, and the heat exchange member 8 is made of a metal material with good heat conductivity, so that heat in the cavity 5 can be rapidly conducted out, the heat exchange area is increased due to the design of the heat dissipation fins 13, and the heat conduction rate and effect are improved. The heat conduction fins 11 and the heat dissipation fins 13 are uniformly distributed, so that the cooling uniformity is improved, if the heat exchange area is smaller, the difference of the heat exchange areas of different parts is relatively larger, so that the influence on the overall uniformity is larger, and as the heat exchange area is increased, the difference of the same area is relatively smaller, so that the influence on the overall uniformity is smaller. The heat conductive medium 12 may be selected from a medium having high heat conductivity and safety such as heat conductive silicone grease or heat conductive glue.
Since the temperature difference between the cooling medium and the heat dissipation portion 10 and the heat dissipation fins 13 is larger when the cooling medium just enters the heat dissipation groove 7, the heat exchange efficiency is higher, and the temperature difference between the cooling medium and the heat dissipation portion 10 and the heat dissipation fins 13 is gradually reduced along with the flow of the cooling medium, the heat exchange efficiency is reduced, and in order to avoid the influence on the uniformity of the heat exchange due to the temperature difference, in one embodiment, as shown in fig. 2 and 3, the cooling medium inlets 14 and the cooling medium outlets 15 of two adjacent heat dissipation grooves 7 are arranged in opposite directions, and the direction from the cooling medium inlets 14 to the cooling medium outlets 15 of the heat dissipation groove 7 is gradually and uniformly thinned. By designing the heat dissipation groove 7 to gradually and uniformly taper from the cooling medium inlet 14 to the cooling medium outlet 15, the radial cross-sectional area gradually becomes smaller along the direction from the cooling medium inlet 14 to the cooling medium outlet 15, so that the flow velocity of the cooling medium gradually becomes faster along the direction from the cooling medium inlet 14 to the cooling medium outlet 15, and under the condition that the flow velocity of the cooling medium is the same but the heat exchange efficiency is low, the heat exchange efficiency is improved by increasing the flow velocity of the cooling medium, so that the heat exchange efficiency in the whole heat dissipation groove 7 is kept as consistent as possible, the heat exchange efficiency in the heat conduction groove 6 is kept as consistent as possible, the heat dissipation uniformity is improved, and the influence of cooling on the product quality is reduced as much as possible. The cooling medium inlets 14 and the cooling medium outlets 15 of two adjacent cooling grooves 7 are arranged in opposite directions, so that one ends of the cooling grooves 7 with larger radial sections and smaller radial sections are arranged in a staggered manner, the occupied areas of the cooling grooves 7 at the two ends are close, and the structural layout is convenient.

When cooling is required, the pump 21 pumps the cooling medium from the cooling medium storage tank 16 through the cooling medium output header pipe 19, sends the cooling medium into the cooling medium output branch pipe 17, then respectively sends the cooling medium into the heat dissipation groove 7 to exchange heat with the heat dissipation part 10 and the heat dissipation fins 13, and then flows back into the cooling medium storage tank 16 to exchange heat with the heat exchanger for recycling after entering the cooling medium return branch pipe 18 and being converged through the cooling medium return header pipe 20, wherein the heat exchange between the heat exchanger and the cooling medium belongs to a conventional technical means and is not repeated. Generally, the hotter cooling medium will rise and the cooler cooling medium will fall, with the cooling medium return port provided in the cooling medium storage tank 16, to facilitate the extraction of the already cooled medium. The cooling medium output branch pipes 17 and the cooling medium return branch pipes 18 are respectively connected with a three-way pipe through pipelines at the middle parts, and the distances from the cooling medium output port to the two cooling medium output branch pipes 17 are equal, and the distances from the cooling medium return port to the two cooling medium return branch pipes 18 are equal.
If the heights of the heat sink 7 are not uniform, the flow rate at the connection of the cooling medium output branch pipe 17 and the heat sink 7 may be affected by gravity, resulting in the non-uniform flow rate at the cooling medium inlet 14 of the heat sink 7, so in one embodiment, as shown in fig. 2, 4 and 5, the fixed mold 3 and the movable mold 4 are disposed opposite to each other in the horizontal direction, the heat conducting groove 6 and the heat sink 7 are disposed in the vertical direction, and a booster pump 22 is disposed between the cooling medium output branch pipe 17 and the cooling medium output manifold 19 located below.
