Description

Technical Field

[0001] This invention belongs to the field of rotary structure mold technology, specifically a double-shot rotary structure mold and its cooling system. Background Technology

[0002] Plastic injection molds are tools used to produce plastic products and have a wide range of applications. In plastic injection molds, some products have both soft and hard plastic materials, which is usually referred to as a two-color mold. However, when the product requires the design of a slider and the mold is relatively large, it will bring many challenges to the mold design.

[0003] Therefore, the staff changed the traditional design of rotating the entire rear mold part of the two-color mold and adopted a design that only supports the plate. This design not only greatly simplifies the mold structure, but also improves the overall quality and service life of the mold, reduces costs, reduces maintenance, and improves production efficiency, which can well meet market demand.

[0004] Based on the aforementioned improvements to the mold, during practical application, staff discovered that cooling is a crucial technology in the production and use of the mold. Effective cooling not only ensures stable mold performance during continuous operation but also significantly improves product quality and production efficiency. Traditional cooling water circuit designs are typically based on static molds, using fixed water channels to deliver coolant to specific parts of the mold for cooling. However, when the mold begins to rotate, these fixed water channels cannot adapt to the dynamic changes in the mold, resulting in insufficient coolant coverage of the mold surface and thus affecting the cooling effect.

[0005] Therefore, the present invention provides a dual-shot rotary mold and its cooling system. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a double-shot rotary mold, which includes a bearing plate, a bearing shaft and a control mechanism. One axial end of the bearing shaft is fixedly connected to the bottom surface of the bearing plate. The bearing plate has a groove in the middle that is adapted to the workpiece. The bearing plate is used to support the workpiece. During processing, the bearing plate is rotated by rotating the bearing shaft, thereby driving the workpiece to rotate.

[0008] The control mechanism includes a control gear ring, a transmission gear plate, a control rod, and a connecting plate. The movable end of the control rod is fixedly connected to the outer wall of the connecting plate. The control rod is a common electric telescopic rod, and its fixed end is connected to an external frame (not shown in the figure). The control rod controls the reciprocating sliding of the connecting plate. The transmission gear plate is fixedly installed on the side wall of the connecting plate. When the connecting plate reciprocates, it drives the transmission gear plate to move synchronously. The control gear ring is set on the outer wall of the bearing shaft and meshes with the transmission gear plate. Rotating the control gear ring controls the synchronous rotation of the bearing shaft. The axis of the bearing shaft coincides with the axis of the control gear ring. Sliding the transmission gear plate drives the control gear ring to rotate, thereby controlling the synchronous rotation of the bearing shaft and the bearing plate to achieve the rotation adjustment of the workpiece.

[0009] A cooling system for a double-shot rotary mold, the system being applied to the aforementioned double-shot rotary mold, includes a quick-connect water nozzle, a connecting pipe, and a cooling nozzle, the cooling nozzle being used to spray coolant during workpiece processing.

[0010] The quick-connect water nozzle is fixedly installed on the upper surface of the support plate. The support plate provides installation and support for the quick-connect water nozzle. The input end of the connecting pipe is connected to the output end of the quick-connect water nozzle. The input end of the quick-connect water nozzle is connected to the external coolant storage chamber. The input end of the cooling nozzle is connected to the output end of the connecting pipe, so as to facilitate the spraying of coolant by the cooling nozzle to cool the workpiece during processing.

[0011] Preferably, a support frame is fitted on the outer wall of the support shaft, a storage ring is fixedly installed on the inner wall of the support frame, the support shaft passes through the storage ring, and a water inlet pipe is fixedly installed on the radial outer wall of the storage ring. The end of the water inlet pipe away from the storage ring is connected to an external coolant storage chamber, and coolant is injected into the inner cavity of the storage ring through the water inlet pipe.

[0012] A sealing plate is provided at the axial end of the storage ring. The sealing plate is used to seal both ends of the storage ring in the axial direction. A drain pipe is fixedly installed on the outer wall of the sealing plate. The other end of the drain pipe is connected to the input end of the quick-connect water nozzle through a conduit to inject coolant into the inner cavity of the storage ring. The coolant enters the quick-connect water nozzle through the drain pipe to cool the workpiece.

[0013] Preferably, the outer wall of the storage ring is provided with a sealed bearing, and the storage ring is connected to the sealing plate through the sealed bearing. The sealed bearing realizes the sealed connection between the storage ring and the sealing plate, and at the same time realizes the rotational connection between the sealing plate and the storage ring. The bearing shaft passes through the sealing plate, and a sealed ring is fixedly installed inside the sealing plate. The bearing shaft is fixedly connected to the sealing plate through the sealed ring, and the inner wall of the sealed ring is fixedly connected to the outer wall of the bearing shaft, thereby realizing the sealed connection between the sealing plate and the bearing shaft.

[0014] Preferably, the inner wall of the support frame is detachably equipped with an mounting block, which is connected to the support frame by bolts. The inner wall of the support frame is provided with a rubber pad that fits the outer wall of the mounting block. The rubber pad has a U-shaped structure and through holes for coolant to pass through on both sides. The inside of the mounting block is provided with through holes for liquid to pass through. After the mounting block is inserted into the support frame, the rubber pad achieves a sealed connection between the mounting block and the support frame. A supply pipe is fixedly installed on the outer wall of the mounting block. The supply pipe is connected to the water inlet pipe through the inner cavity of the mounting block. After the supply pipe is connected to the external coolant storage chamber, the supply pipe provides coolant to the water inlet pipe through the mounting block.

[0015] The inner wall of the mounting block is detachably fitted with a perforated cylinder. The axial end of the perforated cylinder has mesh holes for coolant to pass through. The inner cavity of the perforated cylinder is equipped with a filter plate, which is a common activated carbon plate. When the coolant passes through, it filters out small impurities in the coolant through the filter plate, thereby preventing impurities from entering the interior of the storage ring, reducing the risk of blockage, and improving service life.

[0016] Preferably, an installation shaft is fixedly installed on the inner wall of the mesh cylinder along its axial direction. The outer wall of the installation shaft is fixedly connected to the outer wall of the filter leaf plate. The installation shaft provides an installation position for the filter leaf plate. The other end of the filter leaf plate is fixedly connected to the inner wall of the mesh cylinder, thereby improving the stability of the filter leaf plate installation.

[0017] Multiple filter blades are provided, and the multiple filter blades are evenly distributed in a ring along the axis of the mounting shaft. The filter blades are spirally arranged on the radial outer wall of the mounting shaft. When the coolant passes through the mesh cylinder, it can increase the contact area between the coolant and the filter blades, thereby improving the filtration effect.

[0018] Preferably, a limiting groove is formed on the inner wall of the mounting block, and an elastic frame is fixedly installed at one axial end of the mounting shaft. The elastic frame has a U-shaped structure. Pressing the outer wall of the elastic frame causes the elastic frame to be recessed inward. A limiting pin is fixedly installed on the outer wall of the elastic frame. Pressing the elastic frame controls the limiting pin to converge towards the center. The end of the limiting pin away from the elastic frame is inserted into the limiting groove. The elastic force of the elastic frame pushes the limiting pin, so that the limiting pin has a tendency to be inserted into the limiting groove in real time.

[0019] Preferably, a baffle plate is fixedly installed on the inner wall of the support frame, and a flow hole for liquid to flow is opened on the outer wall of the baffle plate. The position of the flow hole corresponds to the position of the supply pipe, and the coolant discharged from the supply pipe enters the interior of the mounting block through the flow hole in the middle of the baffle plate.

[0020] A control plate is installed between the baffle plate and the supply pipe. A gap is reserved between the outer wall of the control plate and the support frame to allow liquid to pass through, thereby preventing the control plate from blocking the flow of coolant. A rubber plug for sealing the flow hole is fixedly installed on the outer wall of the control plate. Sliding the control plate causes the rubber plug to slide. When it is necessary to remove the mounting block, slide the control plate until the rubber plug is inserted into the flow hole of the baffle plate to seal the flow hole and prevent the coolant remaining in the supply pipe from flowing out after removing the mounting block.

[0021] Preferably, a transmission plate is elastically mounted on the side of the baffle away from the control plate. A spring is provided on the outer wall of the transmission plate, and the other end of the spring is fixedly connected to the outer wall of the baffle. The spring force pushes the transmission plate, so that the transmission plate tends to move away from the baffle in real time. A magnet is provided inside the transmission plate, and a connecting rod is fixedly mounted on the outer wall of the transmission plate. The other end of the connecting rod is fixedly connected to the outer wall of the rubber plug. The transmission plate and the rubber plug are connected through the connecting rod, so that the control plate can be driven to slide by sliding the transmission plate.

[0022] A control block is fixedly installed on the inner wall of the elastic frame. The control block repels the transmission plate by magnetic force. The control block is a common neodymium iron boron magnet. After the mounting block is installed in the support frame, the transmission plate is pushed by the magnetic force of the control block, thereby controlling the separation of the rubber plug from the flow hole.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention incorporates a storage ring. The axial end of the storage ring is connected to a sealing plate via a sealed bearing. A drain pipe is fixedly installed on the outer wall of the sealing plate, and a water inlet pipe is fixedly installed on the radial outer wall of the storage ring. The end of the water inlet pipe furthest from the storage ring is connected to an external coolant storage chamber. During the rotation of the bearing plate controlled by the bearing shaft, the sealing plate rotates synchronously with the bearing shaft, causing the drain pipe to rotate synchronously. As the drain pipe rotates, the storage ring continuously supplies water to the drain pipe, thereby adapting to the coolant supply of the workpiece when the bearing plate rotates, ensuring the cooling quality of the rotating workpiece on the bearing plate.

[0025] 2. This invention features an installation block that can be detachably installed within a support frame. The supply pipe connects to the water inlet pipe through the inner cavity of the installation block. The inner cavity of the mesh cylinder is equipped with a filter plate, which is a common activated carbon plate. When the coolant passes through, the filter plate filters out fine impurities in the coolant, thereby preventing impurities from entering the storage ring, reducing the risk of blockage, and improving service life.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Example 1: As Figures 1 to 5 As shown in the embodiment of the present invention, a double-shot rotary mold includes a support plate 1, a support shaft 5, and a control mechanism. One axial end of the support shaft 5 is fixedly connected to the bottom surface of the support plate 1. The support plate 1 has a groove in the middle that is adapted to the workpiece. The support plate 1 is used to support the workpiece. During processing, the support plate 1 is controlled to rotate by rotating the support shaft 5, thereby driving the workpiece to rotate.

[0039] The control mechanism includes a control gear ring 7, a transmission gear plate 4, a control rod 8, and a connecting plate 6. The movable end of the control rod 8 is fixedly connected to the outer wall of the connecting plate 6. The control rod 8 is a common electric telescopic rod, and its fixed end is connected to an external frame (not shown in the figure). The control rod 8 controls the reciprocating sliding of the connecting plate 6. The transmission gear plate 4 is fixedly installed on the side wall of the connecting plate 6. When the connecting plate 6 reciprocates, it drives the transmission gear plate 4 to move synchronously. The control gear ring 7 is set on the outer wall of the bearing shaft 5 and meshes with the transmission gear plate 4. Rotating the control gear ring 7 controls the bearing shaft 5 to rotate synchronously. The axis of the bearing shaft 5 coincides with the axis of the control gear ring 7. Sliding the transmission gear plate 4 drives the control gear ring 7 to rotate, thereby controlling the bearing shaft 5 and the bearing plate 1 to rotate synchronously, realizing the rotation adjustment of the workpiece.

[0040] A cooling system for a double-shot rotary mold, the system being applied to the aforementioned double-shot rotary mold, includes a quick-connect water nozzle 3, a connecting pipe 2, and a cooling nozzle 12, the cooling nozzle 12 being used to spray coolant during workpiece processing.

[0041] The quick-connect water nozzle 3 is fixedly installed on the upper surface of the support plate 1. The support plate 1 provides installation and support for the quick-connect water nozzle 3. The input end of the connecting pipe 2 is connected to the output end of the quick-connect water nozzle 3, and the input end of the quick-connect water nozzle 3 is connected to the external coolant storage chamber. The input end of the cooling nozzle 12 is connected to the output end of the connecting pipe 2, so that the cooling nozzle 12 can spray coolant to facilitate the cooling of the workpiece during processing.

[0042] The outer wall of the bearing shaft 5 is fitted with a bearing frame 13, and a storage ring 10 is fixedly installed on the inner wall of the bearing frame 13. The bearing shaft 5 passes through the storage ring 10. A water inlet pipe 11 is fixedly installed on the radial outer wall of the storage ring 10. The end of the water inlet pipe 11 away from the storage ring 10 is connected to an external coolant storage chamber. Coolant is injected into the inner cavity of the storage ring 10 through the water inlet pipe 11.

[0043] A sealing plate 14 is provided at the axial end of the storage ring 10. The sealing plate 14 is used to seal both axial ends of the storage ring 10. A drain pipe 9 is fixedly installed on the outer wall of the sealing plate 14. The other end of the drain pipe 9 is connected to the input end of the quick-connect water nozzle 3 through a conduit to inject coolant into the inner cavity of the storage ring 10. The coolant enters the quick-connect water nozzle 3 through the drain pipe 9 to cool the workpiece.

[0044] A sealed bearing is provided on the outer wall of the storage ring 10. The storage ring 10 is connected to the sealing plate 14 through the sealed bearing. The sealed bearing realizes the sealed connection between the storage ring 10 and the sealing plate 14, and also realizes the rotational connection between the sealing plate 14 and the storage ring 10. The bearing shaft 5 passes through the sealing plate 14. A sealing ring 15 is fixedly installed inside the sealing plate 14. The bearing shaft 5 is fixedly connected to the sealing plate 14 through the sealing ring 15. The bearing shaft 5 passes through the sealing ring 15, and the inner wall of the sealing ring 15 is fixedly connected to the outer wall of the bearing shaft 5, thereby realizing the sealed connection between the sealing plate 14 and the bearing shaft 5.

[0045] During the process of the bearing shaft 5 controlling the bearing plate 1 to rotate, the sealing plate 14 rotates synchronously with the bearing shaft 5, driving the drain pipe 9 to rotate synchronously. During the rotation of the drain pipe 9, the storage ring 10 continuously supplies water to the drain pipe 9, thereby adapting to the coolant supply of the workpiece when the bearing plate 1 rotates.

[0046] Example 2: Figures 6 to 9 As shown in Example 1, another embodiment of the present invention is as follows:

[0047] The inner wall of the support frame 13 is detachably equipped with an mounting block 20. The mounting block 20 is connected to the support frame 13 by bolts. The inner wall of the support frame 13 is provided with a rubber pad 21 that is adapted to the outer wall of the mounting block 20. The rubber pad 21 has a U-shaped structure and through holes for coolant to pass through on both sides. The inside of the mounting block 20 is provided with through holes for liquid to pass through. After the mounting block 20 is inserted into the support frame 13, the rubber pad 21 achieves a sealed connection between the mounting block 20 and the support frame 13. A supply pipe 19 is fixedly installed on the outer wall of the mounting block 20. The supply pipe 19 is connected to the water inlet pipe 11 through the inner cavity of the mounting block 20. After the supply pipe 19 is connected to the external coolant storage chamber, the supply pipe 19 provides coolant to the water inlet pipe 11 through the mounting block 20.

[0048] During machining, coolant is a recyclable resource. After being collected and simply filtered, the coolant is discharged again through a controlled water pump. This causes fine impurities in the coolant to enter the inner cavity of the storage ring 10, which can lead to blockage of the cooling system in severe cases.

[0049] The inner wall of the mounting block 20 is detachably fitted with a mesh cylinder 26. The axial end of the mesh cylinder 26 is provided with mesh holes for coolant to pass through. The inner cavity of the mesh cylinder 26 is provided with a filter plate 18, which is a common activated carbon plate. When the coolant passes through, it filters out small impurities in the coolant through the filter plate 18, thereby preventing impurities from entering the interior of the storage ring 10, reducing the risk of blockage, and improving service life.

[0050] An mounting shaft 25 is fixedly installed on the inner wall of the mesh cylinder 26 along its axial direction. The outer wall of the mounting shaft 25 is fixedly connected to the outer wall of the filter leaf plate 18. The mounting shaft 25 provides an installation position for the filter leaf plate 18. The other end of the filter leaf plate 18 is fixedly connected to the inner wall of the mesh cylinder 26, thereby improving the stability of the filter leaf plate 18 installation.

[0051] Multiple filter blades 18 are provided, and the multiple filter blades 18 are evenly distributed in a ring along the axis of the mounting shaft 25. The filter blades 18 are spirally arranged on the radial outer wall of the mounting shaft 25. When the coolant passes through the mesh cylinder 26, it can increase the contact area between the coolant and the filter blades 18, thereby improving the filtration effect.

[0052] The inner wall of the mounting block 20 has a limiting groove 30. An elastic frame 28 is fixedly installed at one axial end of the mounting shaft 25. The elastic frame 28 has a U-shaped structure. Pressing the outer wall of the elastic frame 28 causes the elastic frame 28 to be recessed inward. A limiting pin 29 is fixedly installed on the outer wall of the elastic frame 28. Pressing the elastic frame 28 controls the limiting pin 29 to converge towards the center. The end of the limiting pin 29 away from the elastic frame 28 is inserted into the limiting groove 30. The elastic force of the elastic frame 28 pushes the limiting pin 29, so that the limiting pin 29 has a tendency to be inserted into the limiting groove 30 in real time.

[0053] As the usage time increases, the impurities attached to the outer wall of the filter blade 18 gradually increase, reducing the throughput of the filter blade 18 and causing a decrease in coolant flow. At this time, the mounting block 20 is removed, and then the elastic frame 28 is pressed until the limiting pin 29 separates from the limiting groove 30. Then, the elastic frame 28 and the mesh cylinder 26 are pulled out, and the filter blade 18 is cleaned. After cleaning, the limiting pin 29 is reinserted into the limiting groove 30 to install the mesh cylinder 26. Finally, the mounting block 20 is reassembled with the support frame 13 to prevent impurities from affecting the water flow.

[0054] A baffle plate 24 is fixedly installed on the inner wall of the support frame 13. A flow hole for liquid flow is opened on the outer wall of the baffle plate 24. The position of the flow hole corresponds to the position of the supply pipe 19. The coolant discharged from the supply pipe 19 enters the interior of the mounting block 20 through the flow hole in the middle of the baffle plate 24.

[0055] A control plate 17 is provided between the baffle plate 24 and the supply pipe 19. A gap is reserved between the outer wall of the control plate 17 and the support frame 13 to allow liquid to pass through, thereby preventing the control plate 17 from blocking the flow of coolant. A rubber plug 16 for sealing the flow hole is fixedly installed on the outer wall of the control plate 17. Sliding the control plate 17 drives the rubber plug 16 to slide. When it is necessary to remove the mounting block 20, slide the control plate 17 until the rubber plug 16 is inserted into the flow hole of the baffle plate 24 to seal the flow hole and prevent the coolant remaining in the supply pipe 19 from flowing out after removing the mounting block 20.

[0056] A transmission plate 22 is elastically mounted on the side of the baffle plate 24 away from the control plate 17. A spring is provided on the outer wall of the transmission plate 22, and the other end of the spring is fixedly connected to the outer wall of the baffle plate 24. The spring force pushes the transmission plate 22, so that the transmission plate 22 tends to move away from the baffle plate 24 in real time. A magnet is provided inside the transmission plate 22, and a connecting rod 23 is fixedly mounted on the outer wall of the transmission plate 22. The other end of the connecting rod 23 is fixedly connected to the outer wall of the rubber plug 16. The connection between the transmission plate 22 and the rubber plug 16 is realized through the connecting rod 23, so that the control plate 17 can be driven to slide by sliding the transmission plate 22.

[0057] A control block 27 is fixedly installed on the inner wall of the elastic frame 28. The control block 27 repels the transmission plate 22 by magnetic force. The control block 27 is a common neodymium iron boron magnet. After the mounting block 20 is installed in the support frame 13, the transmission plate 22 is pushed by the magnetic force of the control block 27, thereby controlling the separation of the rubber plug 16 from the flow hole.

[0058] When the installation block 20 is disassembled, the magnetic force of the control block 27 on the transmission plate 22 gradually decreases. At this time, the spring force pushes the transmission plate 22 until the rubber plug 16 is inserted into the flow hole, realizing the automatic sealing of the flow hole, reducing the operation steps and improving the efficiency of cleaning the filter plate 18.
