Description

Technical Field

[0001] The invention relates to the technical field of cooling equipment for injection molding machines, in particular to an injection molding machine with an external cooling system. Background Art

[0002] During the use of the injection molding machine, a cooling medium is needed to control the temperature of the mold and the injection material. The cooling medium enters the mold through a water pump, absorbs heat by contacting the mold surface and the surface of the injection molded part, and then flows back to the water tank through a water pipe. The cycle repeats to achieve cooling during the injection molding process. In order to keep the cooling medium in a cool state when flowing back, another cooling system is set outside the injection molding machine to cool the cooling medium of the injection molding machine. The external cooling system usually uses water to take away the temperature of the cooling medium of the injection molding machine. After being used for a long time, the water is easy to form scale on the outside of the pipe where the cooling medium of the injection molding machine circulates. The scale will affect the cooling effect of water on the cooling medium delivery pipe of the injection molding machine, affect the cooling effect of the injection molded parts, and thus affect the quality of the injection molded parts.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN208215942U, patent name: a cooling device for an injection molding machine) is: it includes an injection molding machine cavity, a feed pipe and a cooling tower, the feed pipe is installed on the side wall of the injection molding machine cavity and is connected to the injection molding machine cavity, the feed pipe runs through the cooling tower, and is characterized in that a condenser is arranged in the cooling tower, the condenser is spirally wound around the feed pipe, and the condenser can be expanded or contracted along the axial direction of the feed pipe, a hydraulic circulation pump is installed on the condenser, a spray pipe is threadedly installed on the side wall of the cooling tower along the horizontal direction, a water pipe is buried in the side wall of the cooling tower, one end of the water pipe is connected to the spray pipe, and the other end extends to the outside of the cooling tower and is connected to a water tank, the spray pipe is located directly above the feed pipe, and water spray ports are evenly spaced at the bottom of the spray pipe; a heat dissipation fan is installed at the top of the cooling tower, a condensation recovery pipe is covered on the top of the heat dissipation fan, the condensation recovery pipe is connected to a collection container, and an air inlet is also opened at the bottom of the side wall of the cooling tower.

[0004] From the above implementation scheme, it can be seen that the cooling device of the injection molding machine is provided with a nozzle and a condenser to cool the feed pipe. As the spray pipe continuously sprays water to the feed pipe, the substances in the water condense into scale over time and adhere to the feed pipe and cannot be removed, which will affect the cooling effect of the feed pipe and further affect the quality of the products molded by the injection molding machine.

DETAILED DESCRIPTION

[0052] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention, and are not used to limit the present invention.

[0053] like Figures 1 to 11 An injection molding machine with an external cooling system shown includes an injection molding machine, the injection molding machine is connected to the cooling system, the cooling system includes a coolant delivery pipeline 1, the coolant delivery pipeline 1 is connected to the mold of the injection molding machine, and the coolant in the coolant delivery pipeline 1 takes away the heat of the mold of the injection molding machine when passing through the mold of the injection molding machine;

[0054] The portion of the coolant delivery pipeline 1 disposed outside the injection molding machine includes a first array of tubes 101 and a second array of tubes 102. The first array of tubes 101 is disposed in the first cooling box 2, and the second array of tubes 102 is disposed in the second cooling box 3. The first cooling box 2 is disposed above the second cooling box 3.

[0055] A first spray assembly 4 is disposed above the first cooling box 2. The first spray assembly 4 sprays liquid toward the first array tube body 101. The water evaporates rapidly when it encounters heat to take away the heat of the coolant.

[0056] A first scale-sweeping assembly 5 is disposed above the first array of tubes 101, and a second scale-sweeping assembly 6 is disposed at the bottom of the first cooling box 2. The first scale-sweeping assembly 5 scrapes away the scale on the first array of tubes 101, and the scale is flushed to the bottom of the first cooling box 2 by water sprayed by the first spray assembly 4. The second scale-sweeping assembly 6 scrapes away the scale accumulated at the bottom of the first cooling box 2 out of the first cooling box 2.

[0057] The water in the second cooling box 3 immerses the second array of tubes 102 therein, so that when the coolant passes through the second array of tubes 102, the heat of the coolant can be transferred to the water in the second cooling box 3, thereby further cooling the coolant, so that the temperature of the coolant can be sufficiently reduced, so that when the coolant returns to the injection mold again, its temperature can reach the set value, so that the coolant can more fully cool the injection molded part.

[0058] A fourth scale scraping assembly 15 is arranged above the second array tube body 102, and a third scale scraping assembly 7 is arranged below the second array tube body 102. The fourth scale scraping assembly 15 scrapes off the scale on the second array tube body 102, and the third scale scraping assembly 7 scrapes off the scale at the bottom of the second array tube body 102 and the bottom of the second cooling box 3.

[0059] Therefore, when the cooling system cools down the coolant delivery pipe 1, the first scale scraping assembly 5, the second scale scraping assembly 6, the third scale scraping assembly 7 and the fourth scale scraping assembly 15 can simultaneously scrape the scale on the outer wall of the coolant delivery pipe 1 to prevent a large amount of scale from solidifying on the outer wall of the coolant delivery pipe 1, thereby affecting the cooling effect of the cooling system on the coolant delivery pipe 1, thereby ensuring that the molds of the injection molding machine can be cooled in time and the quality of the injection molded parts is guaranteed.

[0060] The first cooling box 2 is provided with a first drain port 201, and the second cooling box 3 is provided with a second drain port 301; the first drain port 201 and the second drain port 301 are both connected to the water purification component 9; after the water in the first cooling box 2 and the second cooling box 3 cools down the coolant delivery pipe 1, the water is brought to the water purification component 9 with the scale scraped off the coolant delivery pipe 1.

[0061] The water purification component 9 includes a purification box 901, which is located on the side of the first cooling box 2 and the second cooling box 3. The purification box 901 is provided with a first water inlet 9014 and a second water inlet 9015. The first water inlet 9014 is connected to the first drain 201, and the second water inlet 9015 is connected to the second drain 301. A clean water partition layer 9011 is also provided in the purification box 901. The clean water partition layer 9011 divides the interior of the purification box 901 into a sewage area and a clean water area. The lower ends of the sewage area and the clean water area are connected to the scale sedimentation tank 901. 3 connection, the first water inlet 9014 and the second water inlet 9015 are arranged on one side of the sewage area, after the scale flows into the purification box 901 with the water, the scale is precipitated in the scale sedimentation tank 9013, the scale sedimentation tank 9013 is connected to the external concentrated liquid delivery pump, after the scale accumulates for a certain period of time, the concentrated liquid delivery pump will suck the scale away, and a clean water outlet 9012 is arranged near the upper end of the clean water area, the water in the upper layer of the purification box 901 does not contain scale or contains only a very small amount of scale, and the upper water is transported to the water body rapid cooling component 8 after passing through the clean water outlet 9012.

[0062] An opening and closing cylinder 902 is provided inside the purification box 901, and the opening and closing cylinder 902 is connected to an opening and closing movable plate 903, and the opening and closing movable plate 903 includes a water hole 9031 and a blocking plate 9032; since the second cooling box 3 uses an immersion method to cool the second array tube body 102, the water in the second cooling box 3 is replaced in batches. When the water temperature inside the second cooling box 3 reaches the set temperature, it needs to be replaced. When the push rod of the opening and closing cylinder 902 is retracted, the blocking plate 9032 retreats, and the water from the first water inlet 9014 and the second water inlet 9015 can flow to Scale sedimentation tank 9013. When new low-temperature water needs to be stored inside the second cooling box 3, the push rod of the opening and closing cylinder 902 is pushed out. At this time, the blocking plate 9032 blocks the second water inlet 9015, so that water can be stored inside the second cooling box 3. At this time, the water through hole 9031 is in the middle of the sewage area, so the water entering from the first water inlet 9014 can pass through the water through hole 9031 and finally flow to the scale sedimentation tank 9013; therefore, the setting of the opening and closing movable plate 903 can enable the second cooling box 3 to realize the functions of storing and discharging water, and will not hinder the water from the first cooling box 2 from flowing back to the purification box 901.

[0063] The water rapid cooling component 8 includes a third cooling box 801, in the middle of which an interlayer plate 8011 is arranged, above the interlayer plate 8011 is a heat dissipation layer 8012, below the interlayer plate 8011 is a refrigeration layer 8013, and openings are arranged at both ends of the interlayer plate 8011, through which water can flow from the heat dissipation layer 8012 to the refrigeration layer 8013; the interlayer plate 8011 prevents the refrigeration layer 8013 from being open to the heat dissipation layer 8012 over a large area, thereby enabling better cooling.

[0064] A refrigeration pipe is arranged outside the refrigeration layer 8013, a heat sink 802 is arranged inside the heat sink 8012, and a second spray assembly 14 is arranged on the third cooling box 801. The second spray assembly 14 is connected to the water purification assembly 9, and the water of the water purification assembly 9 is sprayed to the heat sink 802 through the second spray assembly 14. After the water with a certain amount of heat passes through the heat sink 802, a large amount of heat can be taken away. Then the water flows from both ends of the interlayer plate 8011 to the inside of the refrigeration layer 8013, and the refrigeration layer 8013 further cools the water so that the water can maintain a relatively low temperature. An output pipe 8014 is arranged at the bottom of the refrigeration layer 8013, and the water is transported to the first spray assembly 4 located above the first cooling box 2 and to the second cooling box 3 through the output pipe 8014 via the pump body.

[0065] The water circulates among the first cooling box 2, the second cooling box 3, the water purification component 9 and the water rapid cooling component 8, so that the water in the cooling system will not be wasted, achieving energy-saving and environmental protection effects.

[0066] The first spray assembly 4 includes an adjustment base 401, which is slidably connected to a lifting base 402, a threaded fixing block 403 is arranged inside the adjustment base 401, the lifting base 402 is rotatably connected to a lifting bolt 404, the lifting bolt 404 is connected to the threaded fixing block 403, and an adjustment handle 4041 is connected to the top of the lifting bolt 404; the lifting base 402 is connected to a main body 405, and the main body 405 is connected to a plurality of branch bodies 406, and a branch switch 4061 is arranged at one end of the branch body 406 close to the main body 405, and at least one spray head 4062 is arranged on the branch body 406, and the height of the lifting base 402 can be adjusted by rotating the adjustment handle 4041, and the intensity of the spraying of the spray head 4062 can be adjusted and the opening and closing of the spray head 4062 can be controlled through the branch switch 4061, so the spray assembly 4 is more flexible and controllable when in use.

[0067] The first spray assembly 4 and the second spray assembly 14 have the same structure.

[0068] The first dirt scraping assembly 5 comprises a first guide rail 501 , the first guide rail 501 is connected to a first slider 502 , and a wrapping brushing component 503 is connected to the first slider 502 . The first scale body scraping assembly 5 includes a wrapping brushing component 503, and the wrapping brushing component 503 includes a brushing base 5031. The brushing base 5031 is connected to a first arc-shaped brush 5032. Second arc-shaped brushes 5033 are hinged on both sides of the first arc-shaped brush 5032. A spring 5034 is arranged between the first arc-shaped brush 5032 and the second arc-shaped brush 5033. When scraping scale on the surface of the coolant delivery pipe 1, the first arc-shaped brush 5032 contacts the upper surface of the coolant delivery pipe 1, and the two second arc-shaped brushes 5033 are also close to the side of the coolant delivery pipe 1 under the elastic force of the spring 5034. The coolant delivery pipe 1 is a circular pipe. The inner sides of the first arc-shaped brush 5032 and the second arc-shaped brush 5033 are both arc surfaces, which can wrap the outer side of the coolant delivery pipe 1. The first scale body scraping assembly 5 is used in the first cooling box 2. Since the first cooling box 2 adopts a spraying method to the first arrangement pipe body 101 The temperature is lowered, so the scale on the first array tube body 101 is basically concentrated on the top and two sides thereof. The top and two sides of the first array tube body 101 are wrapped by the wrapped brushing component 503. When the wrapped brushing component 503 moves back and forth along the first array tube body 101, the scale on the top thereof can be removed. When the wrapped brushing component 503 moves to the end of the first array tube body 101, the second arc-shaped brush 5033 touches the place where the end of the first array tube body 101 is turned and connected, and it will pry up to the two sides of the first arc-shaped brush 5032, so that the upper surface of the turning part of the end of the first array tube body 101 can also be brushed and cleaned. When the wrapped brushing component 503 leaves the end of the first array tube body 101, due to the elastic force of the spring 5034, the second arc-shaped brush 5033 will return to its original state and continue to be wrapped on both sides of the first array tube body 101, so that a good cleaning effect can be achieved on the first array tube body 101.

[0069] The first dirt-scraping assembly 5 and the fourth dirt-scraping assembly 15 have the same structure.

[0070] The second scale body scraping assembly 6 includes a second slider 602, which is slidably connected to the second guide rail 601, and the second slider 602 is hinged with a shovel plate 603. A shovel plate movable cylinder 604 is arranged below the second slider 602, and the shovel plate movable cylinder 604 is connected to a movable guide block 605. The shovel plate 603 is connected to a movable guide rail 606 on the side facing the shovel plate movable cylinder 604, and the movable guide block 605 is slidably connected to the movable guide rail 606; the second scale body scraping assembly 6 is arranged at the bottom of the first cooling box 2, so that the scale scraped off from the first array of tubes 101 can be pushed to the first array At the water inlet 201, the scale is discharged from the first drain outlet 201 along with the water. When the shovel plate movable cylinder 604 contracts, the bottom end of the shovel plate 603 contacts the bottom surface of the first cooling box body 2. At this time, the second slider 602 moves toward the first drain outlet 201 to shovel the scale to the first drain outlet 201. When the second slider 602 moves away from the first drain outlet 201, the shovel plate movable cylinder 604 is pushed out to push up the shovel plate 603. At this time, the bottom end of the shovel plate 603 does not contact the bottom surface of the first cooling box body 2, so the shovel plate 603 will not bring the scale back when it returns to its original position.

[0071] The third scale-sweeping assembly 7 includes a chain link 703, both ends of the chain link 703 are connected to a chain 702, and the chain 702 is connected to a sprocket 701; the chain link 703 is connected to a deformable brush body 704, and the rotation of the chain 702 drives the deformable brush body 704 to move, and when the deformable brush body 704 moves to the upper side of the third scale-sweeping assembly 7, it scrapes off the scale at the bottom of the second array tube body 102, and when the deformable brush body 704 moves to the lower side of the third scale-sweeping assembly 7, it scrapes the scale accumulated on the bottom side of the second cooling box 3 to one end of the second cooling box 3, because the second cooling box 3 is full of water, if the second scale-sweeping assembly 6 is still used to clean the second cooling box 3, the shovel plate 603 will encounter great resistance during the movement. If the deformable brush body 704 is used to clean the scale, since there are many gaps between the wire brushes 7042, the wire brush 7042 will not encounter great resistance when moving in the water, and the chain 702 is used to drive the deformable brush body 704 to move, so that the deformable brush body 704 always moves toward the second drain port 301 when it is under the chain 702, so the scale is always swept out in the direction of the second drain port 301. After the scale reaches the second drain port 301, it will be discharged along with the water flow when the second cooling box 3 is drained.

[0072] The deformable brush body 704 includes a plurality of brush body connection blocks 7041 connected together, a buckle hole 70411 is provided in the middle of the brush body connection block 7041, and avoidance oblique positions 70412 are provided on both sides of the brush body connection block 7041; a plurality of brush body connection blocks 7041 are connected to a wire brush 7042 on one side away from the buckle hole 70411. The avoidance oblique positions 70412 enable the plurality of brush body connection blocks 7041 to be arranged along the arc bending line when the deformable brush body 704 moves to the turning point of the chain 702, so that the deformable brush body 704 can smoothly switch between the upper and lower sides of the chain 702.
