A slanted-top injection mold with rapid cooling function and its usage method

Abstract

This invention discloses a slanted ejector injection mold with rapid cooling function and its usage method. The invention relates to the field of injection mold technology. It includes a mold base with a cooling mechanism for the slanted ejector injection mold. The invention uses a first cooling pipe to provide annular cooling to the outer side of the mold cavity body, and a third cooling pipe, in conjunction with an annular groove, to provide all-around cooling to the slanted ejector block, covering the critical areas for molding and demolding of the injection molded part. This avoids uneven cooling in certain areas. The coolant adopts a circulating design, entering from the inlet pipe and exiting from the outlet pipe to form a closed loop, continuously carrying away heat from the mold and the injection molded part, achieving rapid cooling, shortening the injection molding cycle. Furthermore, the third cooling pipe and annular groove inside the slanted ejector block rapidly reduce the temperature of the contact surface between the plastic part and the slanted ejector, effectively preventing adhesion during demolding, ensuring product surface quality, avoiding scratches, damage, and other defects, and guaranteeing the smoothness and integrity of the product surface.

Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to a slanted-top injection mold with rapid cooling function and its usage method. Background Technology

[0002] Injection molds are core equipment in the production of plastic products. Angled-top injection molds are widely used in the molding of complex parts in the automotive, home appliance, and electronics industries because they can smoothly demold plastic parts with undercut or side hole features.

[0003] Reference patent (CN218196665U) discloses an injection mold with a cooling structure, including a base, a lower mold fixedly connected to the top of the base, electric push rods fixedly connected to the top of the base and corresponding sides of the lower mold, an upper mold for use with the lower mold fixedly connected to the output end of the electric push rods, a first serpentine tube fixedly connected inside the lower mold, a water tank fixedly connected inside the base, a second serpentine tube rotatably connected inside the water tank, and a first rotary joint fixedly connected between the second serpentine tube and the first serpentine tube; the mold can draw the cooled liquid after heat exchange into the second serpentine tube and cool it with the coolant in the water tank, while simultaneously driving the second serpentine tube to rotate forward, and a stirring rod rotating in the opposite direction to agitate the water in the water tank, thereby improving the cooling efficiency and further enhancing the cooling efficiency of the coolant.

[0004] Based on the aforementioned patent, the cooling efficiency of the mold directly determines the molding cycle and quality of the product during the injection molding process. However, traditional angled ejector injection molds typically only have simple straight-through cooling channels in the fixed mold and moving mold. Due to their small structure and complex movement, the angled ejector pin and angled ejector block areas often cannot be equipped with effective cooling channels, resulting in high temperatures and slow heat dissipation at the contact surface of the angled ejector. This can easily cause the plastic part to stick to the angled ejector during demolding, resulting in scratches, tears, or defects on the product surface. Furthermore, the cooling system of existing molds usually runs continuously during the mold opening and ejection stage. When the coolant continues to circulate, the plastic part will shrink due to over-cooling, thus tightly wrapping around the mold core and angled ejector, forming excessive clamping force. Forced ejection under this state can easily cause defects such as whitening, cracking, or deformation of the plastic part. Therefore, this invention provides an angled ejector injection mold with rapid cooling function and a method of using it. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a slanted ejector injection mold with rapid cooling function and its usage method. This solves the problem that traditional slanted ejector injection molds typically only have simple straight-through cooling channels in the fixed mold and moving mold, while the slanted ejector rod and slanted ejector block areas, due to their small structure and complex movement, often cannot be equipped with effective cooling channels. This results in high temperatures and slow heat dissipation at the contact surface of the slanted ejector, which can easily cause the plastic part to stick to the slanted ejector during demolding, resulting in scratches, tears, or defects on the product surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slanted-ejector injection mold with rapid cooling function, comprising a mold base, wherein the mold base is provided with a cooling mechanism for the slanted-ejector injection mold, the cooling mechanism comprising: The cooling assembly includes a lower mold mounted on a mold base, an upper mold mounted on the lower mold, a push plate inside the mold base, a pair of infusion tubes distributed inside the push plate, an inclined push rod at the upper end of the infusion tubes, an inclined push block movably connected to the upper end of the inclined push rod, a third cooling pipe inside the inclined push block, and an annular groove inside the inclined push block. The cutting assembly includes a slide rail bracket fixed to one side of the push plate, an inlet pipe on one side of the slide rail bracket, a pair of sealing blocks slidably connected inside the slide rail bracket, a connecting block fixed to one side of the lower mold, movable rods movably connected to the lower ends of the connecting block via a rotating shaft on both sides, a driving component at the bottom of the mold base, and push rods fixed to the four ends of the lower mold.

[0007] Preferably, the inclined push rod has a hollow structure, and there is a flow structure between the infusion tube and the inclined push rod.

[0008] Preferably, the upper end of the upper mold is provided with an injection port, the input end of the injection port is located inside the upper mold and a first flow channel is provided, and the two ends of the first flow channel are provided with second flow channels, the first flow channel and the second flow channel are in an I-shaped structure.

[0009] Preferably, the upper mold has a cavity body inside, and a first cooling pipe is embedded inside the upper mold. The first cooling pipe has a ring structure, and multiple sets of the first cooling pipe are evenly distributed on the outside of the cavity body.

[0010] Preferably, the bottom of the inclined top block is provided with a movable groove, the interior of which is movably connected to a movable outer shell, and the movable outer shell is in a flow connection with the inclined top rod. The upper end of the movable outer shell is provided with a flexible hose, and the upper end of the flexible hose is in a flow connection with a third cooling pipe.

[0011] Preferably, the upper end of the third cooling pipe is provided with a conduit, the other end of the conduit is connected to the annular groove, and an output pipe is provided on one side of the lower end of the annular groove.

[0012] Preferably, the inlet pipe and the infusion pipe have a flow structure through the slide rail bracket, and the slide rail bracket has a cavity structure.

[0013] Preferably, the lower end of the movable rod is rotatably connected to the sealing block via a rotating shaft, and the sealing block is used to block the flow between the inlet pipe and the delivery pipe.

[0014] Preferably, the lower mold has a core body inside, and a second cooling pipe with a ring structure is embedded inside the lower mold. One end of the second cooling pipe is provided with a connecting pipe, one end of the connecting pipe is connected to a telescopic pipe, and one end of the telescopic pipe is connected to an infusion pipe.

[0015] This invention also provides a method for using a slanted-ejector injection mold with rapid cooling function, comprising the following steps: Step 1: Inject the raw material through the injection port, and distribute it evenly into the main body of the mold cavity through the first and second runners of the I-shaped mold to complete the injection filling; Step 2: The coolant is fed into the external equipment of the inlet pipe and transported to each cooling pipe through the slide rail bracket, delivery pipe, etc. to achieve circulating cooling and eliminate dead zones; Step 3: The driving component pushes the mold down, which drives the push rod to move the push plate. The inclined push rod and inclined push block are driven upward to complete the demolding.

[0016] This invention provides a slanted-ejector injection mold with rapid cooling function and its usage method. Compared with the prior art, it has the following advantages: Firstly, this invention uses a first cooling pipe to provide annular cooling to the outer side of the mold cavity body, and a third cooling pipe in conjunction with an annular groove to provide all-round cooling to the inclined ejector block, covering the key areas for injection molding and demolding, avoiding uneven local cooling. The coolant adopts a circulating design, entering from the inlet pipe and exiting from the outlet pipe to form a closed loop, which can continuously remove heat from the mold and injection molded parts, achieving rapid cooling and shortening the injection molding cycle. Furthermore, through the third cooling pipe and annular groove inside the inclined ejector block, the temperature of the contact surface between the plastic part and the inclined ejector is rapidly reduced, effectively preventing adhesion during demolding, ensuring product surface quality, avoiding defects such as scratches and damage on the product surface, and ensuring the flatness and integrity of the product surface.

[0017] Secondly, during mold opening, the upper mold is opened by external equipment, the driving component pushes the lower mold, and drives the connecting block to rise and fall. The lower end of the movable rod is rotatably connected to the sealing block through the rotating shaft. The rising and falling of the connecting block brings the two sets of sealing blocks closer to each other, which promptly blocks the flow between the inlet pipe and the delivery pipe, stops the supply of coolant to the first cooling pipe, the second cooling pipe, the inclined ejector rod and the inclined ejector block, and prevents the coolant from continuing to circulate during ejection, causing the product to continue to shrink and tightly wrap around the mold core, resulting in excessive clamping force and causing defects such as tearing and whitening. This ensures the quality of product demolding. Moreover, the sealing block is driven by the lifting action of the lower mold itself, without the need for additional sensors or electronic control components. The structure is simple and the failure rate is low. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 10 The present invention provides the following three technical solutions. First embodiment: A slanted-ejector injection mold with rapid cooling function, including a mold base 1, on which a cooling mechanism for the slanted-ejector injection mold is provided, the cooling mechanism including: The cooling assembly includes a lower mold 2 set on a mold base 1, an upper mold 201 set on the lower mold 2, a push plate 502 set inside the mold base 1, a pair of infusion pipes 508 distributed inside the push plate 502, an inclined push rod 6 set at the upper end of the infusion pipes 508, an inclined push block 601 movably connected to the upper end of the inclined push rod 6, a third cooling pipe 605 set inside the inclined push block 601, and an annular groove 606 opened inside the inclined push block 601. The cutting assembly includes a slide rail bracket 503 fixed to one side of the push plate 502, an inlet pipe 505 on one side of the slide rail bracket 503, a pair of sealing blocks 504 slidably connected inside the slide rail bracket 503, a connecting block 506 fixed to one side of the lower mold 2, movable rods 507 connected by a rotating shaft on both sides of the lower end of the connecting block 506, a driving component 5 at the bottom of the mold base 1, and push rods 501 fixed at the four ends of the lower mold 2. The driving component 5 is used to push the lower mold 2. After pushing the lower mold 2 a certain distance, the lower mold 2 drives the push rods 501 upward. At this time, the protrusion at the lower end of the push rod 501 drives the push plate 502 to move up and down, so that the inclined push rod 6 and the inclined push block 601 on the push plate 502 are driven upward for demolding.

[0022] In this embodiment of the invention, the upper mold 201 has a mold cavity body 3 inside, and a first cooling pipe 301 is embedded inside the upper mold 201. The first cooling pipe 301 has a ring structure, and multiple sets of the first cooling pipe 301 are evenly distributed on the outside of the mold cavity body 3. The inclined ejector rod 6 has a hollow structure, and the liquid inlet pipe 508 has a flow structure with the inclined ejector rod 6. The bottom of the inclined ejector block 601 has a movable groove 602, and a movable outer shell 603 is movably connected inside the movable groove 602. The movable outer shell 603 has a flow connection with the inclined ejector rod 6, and a flexible hose 604 is provided at the upper end of the movable outer shell 603. The upper end of the hose 604 is connected to the third cooling pipe 605. The upper end of the third cooling pipe 605 is provided with a conduit 607. The other end of the conduit 607 is connected to the annular groove 606. An output pipe 608 is provided on one side of the lower end of the annular groove 606. The inlet pipe 505 is used to connect external equipment to the coolant. The coolant enters the slide rail bracket 503 and is sent into the delivery pipe 508. It then enters the interior of the inclined ejector rod 6 and the inclined ejector block 601 in sequence, so that the inclined ejector area is fully cooled. The temperature of the plastic part and the contact surface of the inclined ejector is rapidly reduced, which effectively prevents sticking during demolding and ensures the surface quality of the product.

[0023] Among them, the movable outer shell 603 is movably connected to the movable groove 602, and the flexible hose 604 can be flexibly deformed to adapt to the ejection action of the inclined ejector rod 6 and the inclined ejector block 601, so as to avoid the cooling pipe from breaking or leaking due to the movement of the mold and improve the service life of the mold.

[0024] In this embodiment of the invention, the inlet pipe 505 has a flow structure between the slide rail bracket 503 and the delivery pipe 508. The slide rail bracket 503 has a cavity structure, in which the coolant enters the third cooling pipe 605, the conduit 607 and the annular groove 606 inside the inclined top block 601, and the coolant is output through the outlet pipe 608 for circulating cooling.

[0025] Specifically, the coolant is fed into the external equipment through the inlet pipe 505. The coolant first enters the interior of the slide rail bracket 503. The coolant in the slide rail bracket 503 is then sent to the delivery pipe 508 on the push plate 502. Because the delivery pipe 508 and the inclined push rod 6 form a flow structure, the coolant enters the inclined push rod 6 with a cavity structure. The coolant in the inclined push rod 6 flows into the movable outer shell 603 that is connected to it. Then, it enters the third cooling pipe 605 through the hose 604 at the upper end of the movable outer shell 603. The coolant flows into the annular groove 606 through the conduit 607 at the upper end of the third cooling pipe 605 to cool the inclined push block 601. The cooled liquid is discharged through the output pipe 608 on one side of the lower end of the annular groove 606 to achieve circulating cooling. At the same time, the first cooling pipe 301 in the upper mold 201 is simultaneously supplied with coolant to cool the mold cavity body 3.

[0026] The first cooling pipe 301 surrounds the mold cavity, the second cooling pipe 401 surrounds the mold core, and the third cooling pipe 605 extends into the inclined top, forming a three-dimensional cooling network to eliminate cooling dead zones.

[0027] The second embodiment differs from the first embodiment mainly in that: the lower end of the movable rod 507 is rotatably connected to the sealing block 504 via a rotating shaft, and the sealing block 504 is used to block the flow between the inlet pipe 505 and the delivery pipe 508. The lower mold 2 has a mold core body 4 inside, and a second cooling pipe 401 with a ring structure is embedded inside the lower mold 2. One end of the second cooling pipe 401 is provided with a connecting pipe 402, and one end of the connecting pipe 402 is connected to a telescopic pipe 403. One end of the telescopic pipe 403 is connected to the delivery pipe 508. During the opening... During molding, the upper mold 201 is first opened by external equipment. The driving component 5 is used to push the lower mold 2. At this time, the connecting block 506 is driven to rise and fall, bringing the two sets of sealing blocks 504 closer to each other and blocking the flow between the liquid inlet pipe 505 and the liquid delivery pipe 508 in time. When the liquid delivery pipe 508 is blocked, the coolant supply to the first cooling pipe 301, the second cooling pipe 401, the inclined ejector rod 6 and the inclined ejector block 601 is stopped to prevent the coolant from continuing to circulate during ejection. This would cause the product to continue to shrink and tightly wrap around the mold core, resulting in excessive clamping force and causing defects such as tearing and whitening.

[0028] Specifically, when the drive component 5 is activated, it pushes the lower mold 2 upward. After the lower mold 2 moves upward a certain distance, it drives the push rods 501 at its four ends to move upward synchronously. The protrusion at the lower end of the push rod 501 drives the push plate 502 to move up and down, and the push plate 502 in turn drives the inclined push rod 6 and the inclined push block 601 on it to move upward, thereby realizing the demolding of the injection molded part. During mold opening, the upper mold 201 is opened by external equipment, the driving component 5 pushes the lower mold 2, and drives the connecting block 506 to rise and fall. The lower end of the movable rod 507 is rotatably connected to the sealing block 504 through the rotating shaft. The rise and fall of the connecting block 506 makes the two sets of sealing blocks 504 approach each other, thus blocking the flow between the liquid inlet pipe 505 and the liquid delivery pipe 508 in time.

[0029] The third embodiment differs from the first and second embodiments in that: an injection port 202 is provided at the upper end of the upper mold 201. The input end of the injection port 202 is located inside the upper mold 201 and has a first flow channel 203. Second flow channels 204 are provided at both ends of the first flow channel 203. The first flow channel 203 and the second flow channel 204 form an I-shaped structure to evenly distribute the raw material in the outer shell 301 of the mold cavity. During injection, the raw material enters from the injection port 202 and is evenly distributed in the mold cavity through the first flow channel 203 and the two second flow channels 204. The cooling process after molding is the same as in the first embodiment. The coolant circulates through each cooling pipe to cool the mold. The process of cutting off the coolant when the mold is opened and ejected is the same as in the second embodiment. The I-shaped structure of the first flow channel 203 and the second flow channel 204 ensures that the raw material is evenly distributed in the mold cavity, thus ensuring the product molding quality. Combining the cooling and coolant cutting-off functions of the first two embodiments, it not only ensures sufficient cooling during product molding but also prevents defects caused by cooling problems during demolding, thus comprehensively improving product quality and production stability.

[0030] This invention also provides a method for using a slanted-ejector injection mold with rapid cooling function, comprising the following steps: Step 1: Inject the raw material through injection port 202, and distribute it evenly into the mold cavity body 3 through the first runner 203 and the second runner 204 to complete the injection filling; Step 2: Coolant is input into the external device via the inlet pipe 505 and transported to each cooling pipe via the slide rail bracket 503 and the delivery pipe 508 to achieve circulating cooling and eliminate dead zones. Specifically, coolant is input into the external device via the inlet pipe 505 and sequentially enters the slide rail bracket 503, the delivery pipe 508, and the inclined push rod 6 of the cavity structure. It then flows through the movable outer shell 603 and the hose 604 into the third cooling pipe 605 of the inclined push block 601. It then flows into the annular groove 606 via the conduit 607 to cool the inclined push block 601. The cooled coolant is discharged through the outlet pipe 608 to achieve circulation. At the same time, the annular first cooling pipe 301 in the upper mold 201 simultaneously introduces coolant to cool the mold cavity body 3. Step 3: The driving component 5 pushes the lower mold 2, which drives the push rod 501 to move the push plate 502. The inclined push rod 6 and the inclined push block 601 are driven upward to complete the demolding. Specifically, the driving component 5 at the bottom of the mold base 1 pushes the lower mold 2. The lower mold 2 drives the push rod 501 at all four ends to move upward. The protrusion at the lower end of the push rod 501 drives the push plate 502 to move up and down, which in turn drives the inclined push rod 6 and the inclined push block 601 to push upward to complete the demolding. The movable outer shell 603 is connected to the movable groove 602, and the flexible deformation of the hose 604 is adapted to the ejection action.

[0031] Working principle: The lower mold 2 on the mold base 1 cooperates with the upper mold 201. After injection molding, the coolant is input by the external equipment through the liquid inlet pipe 505. The coolant enters the slide rail bracket 503, the liquid delivery pipe 508, and the inclined ejector rod 6 of the cavity structure in sequence. Then it flows through the movable shell 603 and the hose 604 into the third cooling pipe 605 of the inclined ejector block 601. It flows into the annular groove 606 through the conduit 607 to cool the inclined ejector block 601. The cooled coolant is discharged through the output pipe 608 to achieve circulation. At the same time, the annular first cooling pipe 301 in the upper mold 201 is simultaneously supplied with coolant to cool the mold cavity body 3. After cooling, the drive component 5 at the bottom of the mold base 1 pushes the lower mold 2, and the lower mold 2 drives the four-end push rod 501 upward. The protrusion at the lower end of the push rod 501 drives the push plate 502 to move up and down, which in turn drives the inclined push rod 6 and the inclined push block 601 to push upward, completing the demolding. The movable outer shell 603 is connected to the movable groove 602, and the flexible deformation of the hose 604 adapts to the ejection action. The lower mold 2 is inlaid with an annular second cooling pipe 401. The second cooling pipe 401 is connected to the liquid delivery pipe 508 through the connecting pipe 402 and the telescopic pipe 403. The lower end of the movable rod 507 is rotatably connected to the sealing block 504 through the rotating shaft. When the mold is opened, the upper mold 201 is opened first through external equipment. The driving component 5 pushes the lower mold 2 and drives the connecting block 506 to rise and fall, so that the two sets of sealing blocks 504 are close to each other, blocking the flow of liquid inlet pipe 505 and liquid delivery pipe 508, stopping the delivery of coolant to the first cooling pipe 301, the second cooling pipe 401, the inclined ejector rod 6 and the inclined ejector block 601. Then the lower mold 2 drives the push rod 501, the push plate 502, the inclined ejector rod 6 and the inclined ejector block 601 to complete the demolding, avoiding defects caused by continuous cooling and shrinkage of the product.
