Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to a component processing injection molding device and a use method thereof. Background Art

[0002] Accessory injection molding is a processing method in which thermoplastic or thermosetting plastics are added into a mold, heated to a certain temperature to melt and form, and then cooled and solidified to form a product of the desired shape.

[0003] Existing cooling systems for injection molding machines are mostly configured as water cooling systems, which utilize cooling pipes to be arranged in the mold so that when a cooling medium with a relatively low temperature flows through the mold, the injection molded parts can be cooled down.

[0004] However, the shapes of various accessories are different. When processing some smaller accessories, multiple accessories are usually injection molded at the same time. In order to make the cooling more uniform, multiple pipes are set up to surround the outsides of multiple rows of mold cavities respectively. Multiple pumps are needed to pressurize the multiple pipes respectively, which makes the cooling system very bloated and the equipment cumbersome.

[0005] Most of the current methods use a diverter, in which the injection pipe is connected to multiple cooling pipes through the diverter, so that the coolant in the injection pipe can flow to the multiple cooling pipes through the diverter. However, if the accessory is relatively slender, more pipes need to be set up to ensure uniform cooling of the accessory during molding. However, this will result in a large difference in the distance between different pipes and the injection pipe. When the pressure in the pipe is insufficient, when the diversion is performed in the diverter, the cooling medium will flow into the nearby pipe first, while the cooling medium will flow into the distant pipe more slowly, resulting in different cooling degrees for different accessories. Therefore, the present application proposes an accessory processing injection molding device and a method for using the same. Summary of the invention

However, if the accessory is relatively slender, more pipes need to be set up to ensure uniform cooling of the accessory during molding. However, this will result in a large difference in the distance between different pipes and the injection pipe. When the pressure in the pipe is insufficient, when the diversion is performed in the diverter, the cooling medium will flow into the nearby pipe first, while the cooling medium will flow into the distant pipe more slowly, thereby causing the problem of different cooling degrees for different accessories.

The liquid level in the diverter 51 will rise before entering the vertical section 552 through the bent section 551, thereby allowing the liquid in multiple diverter tubes 55 to uniformly enter the first cooling tube 57 and the second cooling tube 58 through the vertical section 552, thereby making the cooling more uniform and avoiding large differences in cooling time for different accessories, resulting in incomplete molding of the accessories.

[0050] The cooling unit 5 is installed on the fixed mold base 22. After the fixed mold base 22 and the movable mold base 23 are molded together, the cooling unit 5 can be used to evenly cool the fixed mold base 22 and the accessories, so that the accessories can be evenly injection molded.

[0051] First, the driving unit 4 is used to drive the movable mold base 23 to move toward the fixed mold base 22, so as to complete the docking work between the movable mold base 23 and the fixed mold base 22; the injection unit 3 injects the injection material into the injection mold unit 2 until the material enters between the movable mold base 23 and the fixed mold base 22; after the fixed mold base 22 and the movable mold base 23 are molded together, the cooling unit 5 can be used to evenly cool the fixed mold base 22 and the accessories, so that the accessories can be evenly injection molded and completely molded; after the accessories are molded, the driving unit 4 is used again to separate the movable mold base 23 from the fixed mold base 22, and the accessories can be taken out at this time.

[0052] It is particularly disclosed that the carrying unit 1 includes a processing table 11 and a discharging chute 12 . The discharging chute 12 is opened above the processing table 11 , and the discharging chute 12 is located below the box body 21 .

[0055] By utilizing the multiple mold cavities 24 and multiple mold cores 25, after the multiple mold cores 25 are inserted into the multiple mold cavities 24, the movable mold base 23 is abutted against the side of the fixed mold base 22. At this time, the cavity between the mold cavity 24 and the mold core 25 forms an injection cavity. At this time, the injection unit 3 is used to input the injection material into the injection cavity to process the accessories.

[0056] By utilizing the guide rods 27 , the movement of the positioning seat 26 and the movable mold seat 23 can be limited, so that the multiple mold cores 25 can be accurately inserted into the multiple mold cavities 24 .

[0057] Further, the injection unit 3 includes an injection seat 31 and an injection pipe 32, the injection seat 31 is fixedly connected to the fixed mold base 22, one end of the injection pipe 32 is fixedly connected to the injection seat 31, and the other end of the injection pipe 32 is connected to the screw extruder, and the injection pipe 32 injects the material extruded by the screw extruder into the fixed mold base 22;

[0058] A plurality of injection branches 33 are installed inside the injection seat 31 , and one end of the plurality of injection branches 33 is connected to the injection pipeline 32 , and a connecting pipe 34 is opened between the other end of the plurality of injection branches 33 and the plurality of mold cavities 24 .

[0062] It should be particularly emphasized that the cooling unit 5 includes:

[0063] A flow divider 51, the flow divider 51 is fixedly mounted on the top of the fixed mold base 22, a cooling main pipe 53 is mounted on the top of the flow divider 51, and the cooling main pipe 53 injects the cooling medium into the flow divider 51;

[0064] The collector 52 is fixedly installed at the bottom of the fixed mold base 22. The cooling medium flows into the collector 52 after cooling the fixed mold base 22. A return pipe 54 is installed at the end of the collector 52 to recover the cooling medium in the collector 52.

[0065] It should be particularly emphasized that multiple diverter tubes 55 are installed on both sides of the diverter 51, and the multiple diverter tubes 55 are respectively located above the multiple rows of mold cavities 24, and multiple collecting tubes 56 are installed on both sides of the collector 52, and the multiple collecting tubes 56 are respectively located below the multiple rows of mold cavities 24, and a first cooling tube 57 and a second cooling tube 58 are arranged between the bottom end of the diverter tube 55 and the top end of the collecting tube 56, and the first cooling tube 57 and the second cooling tube 58 are respectively located on both sides of the multiple mold cavities 24 in the same row, and the first cooling tube 57 and the second cooling tube 58 are arranged in multiple sections of bends, so that when the cooling medium flows through the first cooling tube 57 and the second cooling tube 58, the multiple mold cavities 24 can be surrounded by cooling.

[0066] During the cooling process, the cooling medium is first injected into the diverter 51 using the cooling main pipe 53, and then the diverter 51 distributes the cooling medium to multiple diverter pipes 55, and the diverter pipes 55 transport the cooling medium to the first cooling pipe 57 and the second cooling pipe 58, and then refluxes to the collecting pipe 56 and enters the collecting pipe 52, and finally the cooling medium in the collecting pipe 52 is recovered through the reflux main pipe 54.

[0067] Because the first cooling tube 57 and the second cooling tube 58 are bent in multiple sections, when the cooling medium flows through the first cooling tube 57 and the second cooling tube 58, multiple mold cavities 24 can be cooled in a surrounding manner, so that the materials in the multiple mold cavities 24 can be cooled and formed more quickly while saving heat loss.

The liquid level in the diverter 51 will rise before entering the vertical section 552 through the bent section 551, thereby allowing the liquid in multiple diverter tubes 55 to uniformly enter the first cooling tube 57 and the second cooling tube 58 through the vertical section 552, thereby making the cooling more uniform and avoiding large differences in cooling time for different accessories, resulting in incomplete molding of the accessories.
