Description

An injection mold with multi-directional heat dissipation

[0001] The present invention relates to an injection mold, in particular to an injection mold with multi-directional heat dissipation, and belongs to the technical field of injection molds.

[0002] An injection mold is a tool or device used to produce plastic products. Its main function is to inject molten plastic material into the mold cavity through the injection molding process, and after cooling and solidification, obtain a plastic product of the desired shape and size.

[0003] When the injection mold is demoulding, in order to make the mold fall off quickly, the upper mold and the lower mold are generally cooled. When cooling the upper mold and the lower mold, the method adopted is generally to set a reasonable cooling water channel in the upper mold, and take away the heat inside the injection mold through the circulating cooling water. Then use a fan or air flow to blow on the upper mold to promote heat dissipation. In this way, the plastic model can be cooled quickly, and a temperature difference can be formed between the upper mold or the lower mold and the plastic model, so that the plastic mold can fall off quickly.

[0004] However, when the injection mold structure device is in use, as the number of times it is used increases, the heat generated during the injection molding process will continue to accumulate on the upper mold and the lower mold. Although most of the heat is taken away by circulating cooling water, the remaining heat will continue to accumulate and affect the demolding of the upper mold or the lower mold. The accumulated heat will also cause the cooling water to continue to heat up, resulting in a reduction in the effectiveness of the cooling water. When the heat is high, the plastic mold will stick to the injection mold. The existing injection mold has a relatively simple method for cooling. Cooling by internal cooling water is not enough to meet the needs of long-term working use, which in turn reduces the practicality of the entire mold structure.

[0005] Therefore, there is an urgent need to improve the injection mold with multi-directional heat dissipation to solve the above-mentioned problems.

[0006] The purpose of the present invention is to provide an injection mold with multi-directional heat dissipation, which can drive the external heat dissipation component to move through the driving component, and then control the contact and separation of the external heat dissipation component with the outer surface of the protrusion. When the external heat dissipation component contacts the protrusion, the external heat dissipation component cools the protrusion, and with the cooperation of the cooling mechanism carried by itself inside and the external heat dissipation component, sufficient cooling is carried out. After frequent and multiple uses of the upper mold, the heat of the protrusion on the upper mold will still be kept at an appropriate temperature, alleviating the problem of overload exceeding the threshold of the cooling mechanism carried by itself inside. With the cooperation of various heat dissipation structures, a multi-directional heat dissipation method is realized, which can better realize the heat dissipation effect of the injection mold and improve the practicality of the injection mold.

[0038] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0039] As shown in Figure 12, the injection mold with multi-directional heat dissipation provided in this embodiment includes a lower mold 1 with a groove 101, an upper mold 2 fixed with a protrusion 201, an external heat dissipation component 3 and an internal heat dissipation component 4. The upper mold 2 is fixedly mounted on a No. 1 fixed base 202, and the lower mold 1 is fixedly mounted on a No. 2 fixed base 103. The No. 1 fixed base 202 and the No. 2 fixed base 103 are both used to be fixed on the injection molding equipment. A telescopic structure 203 is provided on the upper mold 2, and the injection molding equipment controls the movement of the upper mold 2 through the telescopic structure 203. An injection hole 104 is provided on the lower mold 1, and the injection molding equipment injects into the groove 101 through the injection hole 104. When in use, the protrusion 201 is movably connected with the groove 101, and the protrusion 201 is movably engaged with the groove 101. When the protrusion 201 is engaged with the groove 101, the injection molding equipment injects thermoplastic into the gap between the protrusion 201 and the groove 101 through the injection hole 104, and forms a plastic product with a fixed shape according to the shape of the gap. There are two external heat dissipation components 3, which are respectively located on both sides of the protrusion 201 and are symmetrical. The cooperation between the two heat dissipation components can effectively save the placement space of the heat dissipation components and better use the practical injection molding equipment. The two external heat dissipation components 3 are both used to dissipate heat from the outer surface of the protrusion 201. The external heat dissipation component 3 is connected to the driving component 5. The driving component 5 drives the external heat dissipation component 3 to move, thereby controlling the contact and separation of the external heat dissipation component 3 with the outer surface of the protrusion 201. When the external heat dissipation component 3 contacts the protrusion 201, the external heat dissipation component 3 cools the protrusion 201;

[0040] After the injection molding equipment completes the injection molding, and a plastic product is formed between the protrusion 201 and the groove 101, the telescopic structure 203 is started to drive the upper mold 2 to move away from the lower mold 1. After moving to a certain distance, the plastic product moves with the protrusion 201, and the plastic product is lifted up from the protrusion 201 by the telescopic structure 203 and falls off. Then, the driving assembly 5 connected to each of the two external heat dissipation components 3 is used, and then the driving assembly 5 drives the two external heat dissipation components 3 to move synchronously toward the position of the protrusion 201 until the two external heat dissipation components 3 are in contact with the outer surface of the protrusion 201. Under the action of the cooling element, the outer surface of the protrusion 201 is cooled. After a suitable contact time, the driving component 5 is started to move the two external heat dissipation components 3 away from the protrusion 201 until they return to their initial positions. Then the upper mold 2 and the lower mold 1 perform the next injection molding process. At this time, the outer surface of the protrusion 201 on the upper mold 2 is fully cooled by the cooling mechanism carried by itself inside and the cooperation of the external heat dissipation component 3. After the upper mold 2 is used frequently and many times, the heat of the protrusion 201 on the upper mold 2 is still kept at a suitable temperature, which alleviates the problem of the cooling mechanism carried by itself inside exceeding the threshold value:

[0041] The external heat dissipation component 3 is provided with a blowing component 6, and the output ends of the blowing component 6 correspond to the protrusion 201 and the groove 101 respectively. The blowing component 6 blows air toward the protrusion 201 and the groove 101, thereby dissipating heat from the surfaces of the protrusion 201 and the groove 101. When the external heat dissipation component 3 contacts the protrusion 201 and is subjected to a cooling process, the blowing component 6 on the external heat dissipation component 3 blows air toward the outer surface of the protrusion 201 and into the groove 101, thereby accelerating the air flow outside the protrusion 201 and inside the groove 101, and then blowing the residual heat inside the groove 101 and the hot air in the internal space through air cooling, so that they can be quickly evaporated, thereby achieving the purpose of heat dissipation and cooling of the protrusion 201 and the groove 101;

[0042] The internal heat dissipation component 4 is used to dissipate heat for the groove 101. The internal heat dissipation component 4 includes an external cooling element 401, a liquid exchange structure component 402 and a circulating pump 403. A built-in circulating pipe 102 is provided inside the lower mold 1. Cooling liquid flows in the built-in circulating pipe 102. The heat on the lower mold 1 is absorbed and transmitted by the flow of the coolant. The output end of the built-in circulating pipe 102 is connected to the input end of the circulating pump 403. The output end of the circulating pump 403 is connected to the output end of the liquid exchange structure component 402. The liquid structure assembly 402 is used to enhance the cooling effect of the lower mold 1 by replacing the coolant. The external cooling element 401 is used to cool the flowing coolant. The input end of the external cooling element 401 is in contact with the outer surface of the lower mold 1. The external cooling element 401 is used to dissipate heat from the outer surface of the lower mold 1. While the external cooling element 401 is fixedly mounted on the outer surface of the lower mold 1, its input end can absorb the heat emitted from the outer surface of the lower mold 1 and discharge it to a position away from the lower mold 1.

[0043] When the built-in circulation pipe 102 is in use, the No. 1 circulation pump 403 accelerates the flow of the coolant in the built-in circulation pipe 102 by running, and absorbs and carries the heat on the lower mold 1 when flowing. When flowing through the external cooling part 401, the temperature of the coolant itself is reduced after the heat dissipation and cooling treatment of the external cooling part 401. After passing through the liquid replacement structural component 402, it flows into the input end of the built-in circulation pipe 102, thus forming a cycle. After the coolant has been used for a long time, the liquid replacement structural component 402 is operated to replace the flowing coolant. The temperature of the newly replaced coolant is normal, which increases the effect of transferring heat to the lower mold 1, reduces the temperature rise of the coolant itself caused by frequent and long-term use of the coolant, and avoids the reduction of the heat dissipation effect of the lower mold 1 due to the coolant.

[0044] 5 and 6, the external heat dissipation component 3 includes a U-shaped half-circle plate 301, several fixed heat-conducting square tubes 302, a U-shaped No. 1 cooling output tube 303, a U-shaped No. 2 cooling input tube 304, a connecting heat-absorbing tube 305 and a heat sink circulation structure 306. The several fixed heat-conducting square tubes 302 are fixedly connected to the inner wall of the half-circle plate 301 at equal distances. The connecting heat-absorbing tube 305 is fixedly connected to the inside of the fixed heat-conducting square tube 302. The input end of the connecting heat-absorbing tube 305 is connected to the No. 2 cooling input tube 304, and the output end of the connecting heat-absorbing tube 305 is connected to the No. 1 cooling output tube 303. The input end of the No. 1 cooling output tube 303 and the output end of the No. 2 cooling input tube 304 are respectively connected to the heat sink circulation structure 306. The structural member 306 is fixedly mounted on the outer wall of the half-circle plate 301. When the external heat dissipation component 3 contacts the outer surface of the protrusion 201, the fixed heat-conducting square tube 302 contacts the outer surface of the protrusion 201 first. Then, the heat on the outer wall of the protrusion 201 will be absorbed by the fixed heat-conducting square tube 302 as it conducts, and the heat on the protrusion 201 is absorbed by the fixed heat-conducting square tube 302. Then, the heat is absorbed by the connecting heat-absorbing tube 305 inside the fixed heat-conducting square tube 302. Then, under the action of the coolant flowing inside the connecting heat-absorbing tube 305, the heat is absorbed and transported away. In this process, when the blowing component 6 blows air to cool the surface of the protrusion 201, the cold air will simultaneously pass through the position between the two adjacent fixed heat-conducting square tubes 302, thereby having a cooling effect on the fixed heat-conducting square tube 302.

[0045] The fixed heat-conducting square tube 302 is provided with a contact heat-absorbing surface 3020, which is in active contact with the outer surface of the protrusion 201. The contact heat-absorbing surface 3020 is made of a material with good thermal conductivity, which facilitates the fixed heat-conducting square tube 302 to absorb heat from the outer wall of the protrusion 201. The heat sink circulation structure 306 includes a heat sink structure 3061 and a second circulation pump 3062. The heat sink structure 3061 is used to dissipate heat for the coolant flowing in the first cooling output pipe 303 and the second cooling input pipe 304, and the second circulation pump 3062 is used to provide a flow of the coolant. Power, the connected heat absorption tube 305 absorbs heat through the fixed heat-conducting square tube 302 and then absorbs heat from the outer surface of the protrusion 201. Under the action of the second circulation pump 3062, the coolant flows in from the second cooling input tube 304, and absorbs the heat on the fixed heat-conducting square tube 302 when passing through several connected heat absorption tubes 305. Then, it flows into the heat sink structure 3061 through the first cooling output tube 303. The heat sink structure 3061 dissipates the heat carried by the coolant, causing the coolant to cool down, and then flows into the second cooling input tube 304. This process forms a cycle;

[0046] Further, as shown in Figures 8 and 9, the liquid exchange structure component 402 includes a No. 1 liquid storage tank 4021, a No. 1 three-way pipe 4022, a No. 1 three-way valve 4023, a No. 2 liquid storage tank 4024, a No. 2 three-way pipe 4025 and a No. 2 three-way valve 4026, and there are multiple external cooling components 401, and the multiple external cooling components 401 are connected by a conduit. The external cooling component 401 includes a heat dissipation slot 4011 and a rotating fan 4012, and the heat dissipation slot 4011 and the rotating fan 4012 are fixedly connected, and the conduit The first three-way pipe 4022 is connected to the output end of one of the external cooling components 401, and the second three-way pipe 4025 is connected to the input end of the other external cooling component 401. The outer walls of the first liquid storage tank 4021 and the second liquid storage tank 4024 are fixedly connected with the heat dissipation fins 18. The first three-way pipe 4022 is connected to the first three-way valve 4023, and the second three-way pipe 4025 is connected to the second three-way valve 4026. The two output ends of the first three-way pipe 4022 are connected to the first liquid storage tank 4021 and the second liquid storage tank 4024. The input end of the No. 1 liquid storage tank 4021 is connected to the input end of the No. 2 liquid storage tank 4024, and the input end of the No. 2 three-way pipe 4025 is connected to the output end of the No. 1 liquid storage tank 4021 and the No. 2 liquid storage tank 4024 respectively. When the liquid exchange structure component 402 is used, the superheated coolant flows from one input end of the No. 1 three-way pipe 4022 to the No. 1 liquid storage tank 4021, and the pipeline on the No. 2 three-way pipe 4025 connected to the No. 1 liquid storage tank 4021 is closed by using the No. 2 three-way valve 4026. When most of the coolant flows into the No. 1 liquid storage tank After 4021, the pipeline connected to the No. 1 liquid storage tank 4021 on the No. 1 three-way valve 4023 is closed, and the pipeline between the No. 1 three-way pipe 4022 and the No. 2 liquid storage tank 4024 is connected. At this point, after most of the flowing coolant is collected, the remaining coolant is mixed with the coolant in the No. 2 liquid storage tank 4024 and flows into the built-in circulation pipe 102. During the mixing, the higher temperature coolant and the lower temperature coolant are mixed, which can quickly cool down the higher temperature coolant.

[0047] 6 and 12, the blowing assembly 6 includes a No. 1 air outlet plate 601 and a No. 2 air outlet plate 602.

A plurality of No. 1 air outlets 7 are provided on the side surface of the No. 1 air outlet plate 601 close to the half-circle plate 301. The No. 2 air outlet plate 602 is fixedly connected to the side surface of the No. 1 air outlet plate 601 away from the No. 1 air outlet 7, and the No. 1 air outlet plate 601 and the No. 2 air outlet plate 602 are connected to each other.

[0048] A plurality of No. 2 air outlets 8 are provided on the side of the No. 2 air outlet plate 602 close to the lower mold 1. A plurality of No. 3 air outlets 9 are provided on the side of the No. 2 air outlet plate 602 facing the vertical surface of the lower mold 1. A telescopic air inlet pipe 10 is connected to the side of the No. 1 air outlet plate 601. An air pump 15 is provided at the input end of the telescopic air inlet pipe 10. The air pump 15 blows air into the No. 1 air outlet plate 601 and the No. 2 air outlet plate 602 through the telescopic air inlet pipe 10. The air inside the No. 1 air outlet plate 601 is blown toward the outer surface of the protrusion 201 and the inner side of the half-circle plate 301 through the No. 1 air outlet 7. The air inside the No. 2 air outlet plate 602 is blown toward the inside of the groove 101 through the No. 2 air outlet 8. The air inside the No. 2 air outlet plate 602 is blown toward the vertical surface of the upper mold 2 through the No. 3 air outlet 9. The air is blown into the No. 1 air outlet plate 601 through the air pump 15, and then blown out through the No. 1 air outlet 7. When blowing out, To dissipate the heat on the outer wall of the protrusion 201, when the air pump 15 ventilates the No. 1 air outlet plate 601, the No. 2 air outlet plate 602 connected thereto will also receive air from the air pump 15, and the No. 2 air outlet plate 602 will blow air into the interior of the groove 101 through the No. 2 air outlet 8, thereby dissipating the heat inside the groove 101 to achieve the purpose of cooling. When the No. 2 air outlet plate 602 blows air to the outside through the No. 3 air outlet 9, the No. 3 air outlet 9 will move with the movement of the external heat dissipation component 3. When it moves, its lateral blowing effect will blow air to the surface of the plastic product on the protrusion 201, thereby enabling the surface of the plastic product to achieve the purpose of rapid cooling. When the two external heat dissipation components 3 are in contact with each other, the No. 3 air outlets 9 on the two external heat dissipation components 3 are connected to each other, which will make the wind force of the No. 2 air outlet 8 stronger and the effect more obvious.

[0049] Furthermore, as shown in Figures 4 and 7, vertical support plates 14 are fixedly connected to the No. 2 fixed base 103 near the four corners of the lower mold 1, and horizontal support plates 17 are fixedly connected to the two adjacent vertical support plates 14, and the horizontal support plates 17 are slidingly connected to the long rectangular grooves 110. The two vertical groove plates 11 are more stable when sliding on the horizontal support plates 17, and the air pump 15 is fixedly installed on the vertical support plates 14, and the two vertical support plates 14 are fixedly connected to the motor mounting plates 16.

[0050] The driving assembly 5 includes a rack 501, a gear 1 502, a short rotating rod 503 and a bevel gear 1 504. The short rotating rod 503 is rotatably connected to the vertical support plate 14. There are two racks 501 and two gears 1 502. The two racks 501 are respectively fixedly connected to the side surface of one side of the vertical slot plate 11. The two gears 1 502 are both fixedly connected to the short rotating rod 503. The gear 1 502 is meshed with the rack 501. One end of the short rotating rod 503 passes through the vertical support plate 14 and is fixedly connected to the bevel gear 1 504.

[0051] The driving assembly 5 also includes a long rotating rod 505, a bevel gear 2 506, a driven gear 507, a driving gear 508 and a motor 1 509. There are two bevel gears. The long rotating rod 505 is rotatably connected to the vertical support plate 14. The two bevel gears 2 506 are fixedly connected to the two ends of the long rotating rod 505, and the bevel gear 2 506 is meshed with the bevel gear 1 504. The driven gear 507 is fixedly connected to the center position of the long rotating rod 505. The motor 1 509 is fixedly mounted on the motor mounting plate 16. The driving gear 508 is connected to the output end of the motor 1 509. The driving gear 508 is meshed with the driven gear 507. The motor 1 509 is started. Under the action of the driving gear 508, the driven gear 507 is driven. The gear 507 rotates, thereby driving the long rotating rod 505 to rotate. When the long rotating rod 505 rotates, it drives the bevel gear 2 506 at both ends to rotate, thereby driving the bevel gear 1 504 to rotate. When the bevel gear 1 504 rotates, it drives the short rotating rod 503 to rotate, thereby driving the gear 1 502 to rotate. Then, the gear 1 502 engages with the rack 501, and the rack 501 drives the vertical slot plate 11 to move, thereby driving the external heat dissipation component 3 to move. The rotation of the short rotating rods 503 on both sides is opposite in clockwise direction. Therefore, when the motor 1 509 is running, it will drive the two external heat dissipation components 3 to move in relative directions or in opposite directions.

[0052] Two vertical slot plates 11 are fixedly connected to the outer wall of the half-circle plate 301, and a long rectangular slot 110 is opened on the vertical slot plate 11. The inner walls on both sides of the long rectangular slot 110 are respectively fixedly connected with a No. 1 buffer pad 12 and a No. 2 buffer pad 13. When the vertical slot plate 11 drives the external heat dissipation component 3 to move, when starting and stopping, under the action of the No. 1 buffer pad 12 and the No. 2 buffer pad 13, the external heat dissipation component 3 is prevented from vibrating greatly when it stops after moving, and under the action of the No. 1 buffer pad 12 and the No. 2 buffer pad 13, the collision force generated when the two external heat dissipation components 3 contact each other is reduced, thereby reducing structural damage.

[0053] As shown in FIG12 , the principle of the injection mold with multi-directional heat dissipation provided by the present invention is as follows: when in use, when the protrusion 201 is disengaged from the groove 101 and the plastic product falls off, the motor 1 509 is started, and under the action of the driving gear 508, the driven gear 507 is driven to rotate, thereby driving the long rotating rod 505 to rotate, and while the long rotating rod 505 rotates, the bevel gear 2 506 at both ends is driven to rotate, thereby driving the bevel gear 1 504 to rotate, and when the bevel gear 1 504 rotates, the short rotating rod 503 is driven to rotate, thereby driving the gear 1 502 to rotate, and then the gear 1 502 is meshed with the rack 501, and the rack 501 drives the vertical groove 502 to rotate. The plate 11 moves, thereby driving the external heat dissipation component 3 to move, and the short rotating rods 503 on both sides rotate in opposite clockwise directions. Therefore, when the motor 1 509 is running, it will drive the two external heat dissipation components 3 to move in relative directions, thereby controlling the contact and separation of the external heat dissipation component 3 with the outer surface of the protrusion 201. When the external heat dissipation component 3 contacts the protrusion 201, the external heat dissipation component 3 cools the protrusion 201. When cooling, the fixed heat-conducting square tube 302 contacts the outer surface of the protrusion 201 first, and then the heat on the outer wall of the protrusion 201 will be absorbed by the fixed heat-conducting square tube 302 as it is conducted by the fixed heat-conducting square tube 302. The heat is absorbed by the connecting heat absorbing tube 305 inside the fixed heat-conducting square tube 302, and then the heat is absorbed and transported away under the action of the coolant flowing inside the connecting heat absorbing tube 305. In this process, when the blowing component 6 blows air to cool the surface of the protrusion 201, the cold air will pass through the position between the two adjacent fixed heat-conducting square tubes 302 at the same time, thereby having a cooling effect on the fixed heat-conducting square tubes 302. When the external heat dissipation component 3 is in operation, the liquid exchange structure 402 component is used to dissipate heat for the lower mold 2. When the liquid exchange structure component 402 is in use, the overheated coolant flows from one input end of the No. 1 three-way pipe 4022 to the No. 1 liquid storage tank 4021, and the No. 2 three-way pipe 4025 is cooled. The pipeline connected to the No. 1 liquid storage tank 4021 is closed by using the No. 2 three-way valve 4026. After most of the coolant flows into the No. 1 liquid storage tank 4021, the No. 1 three-way valve 4023 is used to close the pipeline on the No. 1 three-way pipe 4022 connected to the No. 1 liquid storage tank 4021, and the pipeline between the No. 1 three-way pipe 4022 and the No. 2 liquid storage tank 4024 is connected. At this point, after most of the flowing coolant is collected, the remaining coolant is mixed with the cooling phase in the No. 2 liquid storage tank 4024 and flows into the built-in circulation pipe 102. During the mixing, the higher temperature coolant and the lower temperature coolant can quickly cool down the higher temperature coolant when mixing.
