Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an automobile injection mold with an external cooling system. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] Some automotive parts are made of plastic auto parts of various shapes by injection molding, which uses plastic molding molds to make thermoplastics or thermosetting plastics. After the material is molded in the injection mold, it cools slowly, and the time for the plastic melt to dissipate heat naturally is too long, which affects the efficiency of component molding. At the same time, it will occupy the injection mold for a long time, affecting the secondary use of the mold and resulting in low processing efficiency. Therefore, it is necessary to develop an automotive injection mold with an external cooling system. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-Figure 5 , shows a schematic diagram of the structure of an automobile injection mold with an external cooling system according to the utility model, please refer to Figure 1-Figure 5 , a detailed introduction is given to an automobile injection mold with an external cooling system.

[0029] An automobile injection mold with an external cooling system includes a processing table 100, a mounting groove 110 is provided on the top right side of the processing table 100, and a mounting table 120 is fixedly provided on the bottom wall of the mounting groove 110;

[0030] A rotating ring 200 is rotatably provided at the middle of the outer wall of the mounting platform 120, a cooling fan 210 is provided on the top of the rotating ring 200, and a driving component for driving the rotating ring 200 to rotate is provided on the processing platform 100;

[0031] The mold body 300 is arranged at the top center of the mounting table 120, and a heat-conducting pipe 330 is arranged around the outer shell of the mold body 300 from top to bottom. The outer shell of the mold body 300 and the heat-conducting pipe 330 are both made of materials with good thermal conductivity, such as copper, aluminum, etc., which are conducive to heat conduction. An industrial chiller 310 is arranged on the left side of the top of the processing table 100, and a water outlet pipe 320 is connected to the water outlet end of the industrial chiller 310, and a water inlet pipe 340 is arranged at the water inlet end. The other end of the water outlet pipe 320 is connected to one end of the heat-conducting pipe 330, and the other end of the water inlet pipe 340 is connected to the other end of the heat-conducting pipe 330.

[0032] Furthermore, the driving assembly includes an outer tooth 220 arranged in a circle outside the rotating ring 200, and the inner cavity of the processing table 100 is rotatably provided with a vertical rotating shaft 230. The shaft of the rotating shaft 230 is provided with a gear 240 that meshes with the outer tooth 220. When the rotating shaft 230 rotates, the rotating ring 200 is driven to rotate through the gear 240 and the outer tooth 220, so that the cooling fan 210 rotates around the mold body 300 and the heat pipe 330.

[0033] Furthermore, a vertical forward and reverse motor 250 is fixedly provided on the right side of the top of the processing table 100. The output shaft of the forward and reverse motor 250 rotates through the top wall of the processing table 100 and is connected to the upper end of the rotating shaft 230 through a coupling. After the forward and reverse motor 250 is started, the rotating shaft 230 is driven to rotate.

[0034] Furthermore, a groove 260 is formed in the middle of the outer wall of the mounting platform 120, and a bearing 270 is protruded from the inner side of the rotating ring 200. The bearing 270 is disposed in the groove of the groove 260. The friction force of the rotating ring 200 is reduced when the rotating ring 200 rotates by the bearing 270.

[0035] Furthermore, the air outlet of the air cooler 210 is always set with a gap from the heat pipe 330, the air outlet direction of the air cooler 210 is toward the center of the mounting platform 120, and the air cooler 210 never touches the water outlet pipe 320 and the water inlet pipe 340, so as to avoid collision between the rotating air cooler 210 and the water outlet pipe 320, the water inlet pipe 340 and the heat pipe 330.

[0036] Furthermore, pumps are respectively provided on the water outlet pipe 320 and the water inlet pipe 340, and the pumps are not in contact with the air cooler 210. The two pumps are not shown in the figure. The first pump can be fixed on the side wall or top of the industrial chiller 310, and the second pump can be fixed on the top of the processing table 100 or the inner cavity of the processing table 100; the water inlet end of the first pump is connected to one end of the water outlet pipe 320, and the water outlet end is connected to one end of the heat conduction pipe 330; the water inlet end of the second pump is connected to the other end of the heat conduction pipe 330, and the water outlet end is connected to one end of the water inlet pipe 340. By setting up the water pump, the fluidity of the water body can be improved.

[0037] Furthermore, the water inlet pipe 340 is in a "U" shape as a whole, and one end of the water inlet pipe 340 passes through the top wall of the mounting table 120, and the other end passes through the top wall of the processing table 100, and the water inlet pipe 340 is never in contact with the swivel 200 and the air cooler 210. Since the air cooler 210 needs to rotate around the heat pipe 330, the water inlet pipe 340 is in a "U" shape as a whole, and passes through the top of the mounting table 120 and the top of the processing table 100 to avoid collision with the water inlet pipe 340 when the air cooler 210 rotates.

[0038] In the specific use process, when the mold injection is completed, the temperature of the mold is transferred to the heat pipe 330 through the mold body 300 with good thermal conductivity. After the water inside the heat pipe 330 absorbs heat, the mold is indirectly cooled. Then the forward and reverse motors 250 are started to drive the rotating shaft 230 to rotate, and the rotating ring 200 is driven to rotate through the gear 240 and the outer gear 220, so that the air cooler 210 rotates around the mold body 300 and the heat pipe 330. After starting the air cooler 210, the fluidity of the air is increased, which is beneficial to the heat dissipation of the mold body 300 and the heat pipe 330. In addition, the industrial chiller 310 and the water pump can also be started to send the water after the heat pipe 330 absorbs heat into the industrial chiller 310 for cooling. The cold water inside the industrial chiller 310 is supplemented into the interior of the heat pipe 330, thereby realizing the injection of cold water into the heat pipe 330 to accelerate the cooling of the mold.

In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
