Abstract
Description
Technical Field
[0001] This invention belongs to the field of injection mold technology, specifically relating to an injection mold for swimming goggles with a cooling function. Background Technology
[0002] In the injection molding process of swimming goggles, the mold temperature has a decisive impact on product quality. After injection molding, the molten plastic needs to be cooled and solidified rapidly and evenly within the mold cavity to obtain swimming goggle products with stable dimensions and a smooth surface.
[0003] The announcement number CN117067540B describes a rapid cooling bottle cap injection mold, which includes a base plate. A water tank is fixedly installed at the center of the top surface of the base plate. A lower mold is fixedly installed at the top of the water tank, and an upper mold is fitted to the top of the lower mold. A water pusher is fixedly installed on the upper mold. A driving component is fixedly installed on the outer walls of both ends of the water tank. Several stirring rods are evenly arranged side by side at the center of the top surface of the lower end of the water pusher, and the upper ends of the stirring rods are movably installed on the bottom surface of the lower mold.
[0004] This rapid-cooling bottle cap injection mold allows cooling water to enter the cooling tank of the lower mold under the drive of the sealing push plate, absorb the heat of the injection molded part, and then flow back to the water tank. However, it lacks a heat exchange structure to dissipate the heat to the outside, which means that the heat transferred by the injection molded part cannot be effectively dissipated from the water tank. The heat continues to accumulate inside the water tank, and as the number of consecutive injections increases, the temperature difference between the cooling water and the injection molded part continues to decrease, thus failing to achieve an effective cooling effect.

[0007] According to the above technical solution, a hydraulic cylinder is fixedly connected to the bottom of the support platform, a connecting block A is fixedly connected to the output shaft of the hydraulic cylinder, and an upper mold is fixedly connected to the inner side of the connecting block A.
[0008] According to the above technical solution, the control component includes a connecting rod, a moving rod A, a connecting rod A, a sliding rod, a conical plug, and a sealing ring. The connecting rod is hinged to the outer wall of the sliding block A. The moving rod A is hinged to the other end of the connecting rod and slides through the cooling box. The connecting rod A is fixedly connected to the end of the moving rod A located outside the cooling box. The sliding rod is fixedly connected to the other end of the connecting rod A and slides through the water outlet pipe. The conical plug is fixedly connected to the end of the sliding rod located inside the water outlet pipe. The sealing ring is fixedly installed inside the water outlet pipe, and the conical plug is inserted into the middle of the sealing ring.
[0009] According to the above technical solution, a ring is fixedly sleeved on the outer wall of the moving rod A, and a spring A is fixedly connected between the ring and the inner wall of the cooling box.
[0010] According to the above technical solution, the bow-shaped plate is slidably connected to the inner wall of the cooling box, and a sealing ring is provided on the edge of the bow-shaped plate. One-way pressure valves are provided inside the connecting pipe A and the connecting pipe B.
[0011] According to the above technical solution, the upper end of the moving rod A is fixedly connected to the connecting rod B, the other end of the connecting rod B is fixedly connected to the moving rod B, the other end of the moving rod B extends into the interior of the cooling box and is fixedly connected to the inclined plate, the inner side of the inclined plate is provided with an inclined groove, the bottom of the lower mold is provided with a through hole, the interior of the through hole is slidably connected to the ejector rod, and the inner side of the ejector rod is rotatably connected to the roller.
[0012] According to the above technical solution, the end of the roller away from the ejector rod is slidably connected inside the inclined groove, and four ejector rods are provided, which are symmetrical in pairs with the center line of the mold as the axis.
[0013] According to the above technical solution, a stirring shaft is rotatably connected to both sides of the protrusion of the bow-shaped plate, a stirring rod is fixedly connected to the outer wall of the stirring shaft, a gear is fixedly sleeved on the inner side of the stirring shaft located in the protrusion of the bow-shaped plate, and a toothed plate is fixedly connected to the outer wall of the moving rod A.

[0015] The advantages of this application are: (1) In this application, the moving seat B and the bow plate are pushed up in stages by the electric telescopic rod. In the initial stage, the coolant fills the cooling chamber to cool the injection molded part. Then, the one-way valve is opened to make the coolant dynamically circulate and cool through the rotary heat exchanger. At the same time, when the bow plate rises, the moving rod A and the slide rod are pushed inward by the connecting rod, and the conical plug is pulled out from the sealing ring to open the water outlet pipe, which ensures the smooth operation of the cooling cycle and effectively improves the cooling efficiency and molding quality of the injection molded part.
[0016] (2) When the moving rod A slides outward, the inclined plate moves through the connecting rod B and the moving rod B. The inclined groove pushes the roller and the ejector rod to slide upward and extend, ejecting the cooled and molded swimming goggle injection part from the lower mold cavity. This achieves the linkage effect of automatic ejection after the injection part has cooled, improving the automation level and production efficiency of injection molding and part removal.
[0017] (3) When the moving rod A slides, it drives the toothed plate to move back and forth, driving the gear and stirring shaft to rotate, so that the stirring rod continuously stirs the coolant inside the cooling box, effectively avoiding the temperature stratification of the coolant due to long-term stillness, ensuring that the coolant temperature in each area inside the cooling box is consistent, avoiding the impact of local temperature differences on the cooling effect of the injection molded parts, and improving the consistency of cooling efficiency and injection molded part molding quality.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.
[0021] Example 1, as Figures 1-6 As shown, a swimming goggle injection mold with cooling function includes a support platform 11, a support leg 12 fixedly connected to the bottom of the support platform 11, a cooling box 2 assembled on the top of the support platform 11, and a lower mold 31 fixedly connected to the top of the cooling box 2. A cooling chamber 41 is provided at the bottom of the lower mold 31. A fixed rod 42 is fixedly connected to the bottom of the interior of the cooling box 2. A slider A43 is slidably connected to the outside of the fixed rod 42. A movable seat A44 is fixedly connected to the inside of the slider A43. A slide rail 45 is mounted on the outer wall of the movable seat A44. A slider B46 is slidably connected to the outer wall of the slide rail 45. A movable seat B47 is fixedly connected to the outside of the slider B46. An electric telescopic rod is mounted at the bottom of the support platform 11, and the output shaft of the electric telescopic rod extends into the interior of the cooling box 2 and is fixedly connected. There is a connecting block B48, which is fixedly connected to the movable seat B47. The upper end of the movable seat A44 is fixedly connected to the bow plate 49. Rotary heat exchangers 410 are installed on both sides of the cooling box 2. The inlet and outlet of the rotary heat exchanger 410 are respectively equipped with an inlet pipe 411 and an outlet pipe 413. The inner side of the inlet pipe 411 and the outlet pipe 413 are equipped with a connecting pipe A412 and a connecting pipe B414, and the other end of the connecting pipe A412 and the connecting pipe B414 are located inside the cooling box 2. The interior of the cooling tank 2 and the interior of the water outlet pipe 413 are equipped with control components for controlling the water outlet.
[0022] A hydraulic cylinder 32 is fixedly connected to the bottom of the support platform 11. A connecting block A33 is fixedly connected to the output shaft of the hydraulic cylinder 32. An upper mold 34 is fixedly connected to the inner side of the connecting block A33.
[0023] The control components include a connecting rod 415, a moving rod A416, a connecting rod A417, a sliding rod 418, a conical plug 419, and a sealing ring 422. The connecting rod 415 is hinged to the outer wall of the slider A43. The moving rod A416 is hinged to the other end of the connecting rod 415 and slides through the cooling box 2. The connecting rod A417 is fixedly connected to the end of the moving rod A416 located outside the cooling box 2. The sliding rod 418 is fixedly connected to the other end of the connecting rod A417 and slides through the water outlet pipe 413. The conical plug 419 is fixedly connected to the end of the sliding rod 418 located inside the water outlet pipe 413. The sealing ring 422 is fixedly installed inside the water outlet pipe 413, and the conical plug 419 is inserted into the middle of the sealing ring 422.
[0024] A ring 421 is fixedly sleeved on the outer wall of the moving rod A416, and a spring A420 is fixedly connected between the ring 421 and the inner wall of the cooling box 2.
[0025] The bow-shaped plate 49 is slidably connected to the inner wall of the cooling box 2, and a sealing ring is provided on the edge of the bow-shaped plate 49. One-way pressure valves are provided inside the connecting pipes A412 and B414. By providing the sealing ring, the sealing between the bow-shaped plate 49 and the inner wall of the cooling box 2 is ensured when the bow-shaped plate 49 slides up and down inside the cooling box 2, preventing the coolant from leaking from the edge of the bow-shaped plate 49 and ensuring that the bow-shaped plate 49 can effectively push the coolant upward. The one-way pressure valve remains closed when the coolant pressure does not reach the set value, so that the coolant first fills the cooling chamber 41 for static cooling in the initial stage.
[0026] In practical use, after successful injection molding, the upper mold 34 and lower mold 31 close and are molded, allowing for cooling. First, the electric telescopic rod is activated, pushing the connecting block B48 and the moving seat B47 upwards. The moving seat B47 slides upwards along the slide rail 45 via the slider B46, simultaneously pushing the moving seat A44 and the bow plate 49 upwards. During the initial rising phase of the bow plate 49, it pushes the coolant inside the cooling tank 2 upwards, completely filling the cooling chamber 41 at the bottom of the lower mold 31. Because the connecting pipes A412 and B414 are equipped with one-way pressure valves, the initial pressure of the coolant is insufficient to open these valves. Therefore, the coolant cannot enter the connecting pipe A412 but remains in the cooling chamber 41 to statically cool the molded part, allowing it to cool and solidify rapidly. After the arc-shaped plate 49 rises to the point where it is completely filled with the cooling chamber 41, it stays for a period of time to allow the injection molded part to be fully cooled in the cooling chamber 41 to ensure molding quality. Then, the electric telescopic rod continues to push the moving seat B47 to move upward. Since the moving seat B47 has already slid to its maximum stroke on the slide rail 45 at this time, the moving seat B47 cannot continue to slide upward along the slide rail 45, thus pushing the entire moving seat A44 and the arc-shaped plate 49 to continue to move upward. The arc-shaped plate 49 applies greater pressure to the coolant in the cooling chamber 41. When the pressure exceeds the opening pressure of the one-way pressure valve, the one-way pressure valve opens, and the coolant enters the water inlet pipe 411 through the connecting pipe A412 and is cooled down by the rotary heat exchanger 410. As the movable seat A44 rises to push the coolant into the connecting pipe A412, the slider A43 pushes the movable rod A416 to slide towards the inside of the cooling box 2 via the connecting rod 415. The movable rod A416 drives the connecting rod A417 and the sliding rod 418 to slide towards the inside of the outlet pipe 413. The sliding rod 418 pulls the conical plug 419 out of the sealing ring 422, and the outlet of the outlet pipe 413 is opened. The coolant, after being cooled by the rotary heat exchanger 410, flows back from the outlet pipe 413 to the inside of the cooling box 2 through the connecting pipe B414, completing the cooling cycle. After cooling is complete, the electric telescopic rod retracts, the movable seat B47 and movable seat A44 descend to reset, the bow plate 49 descends, the spring A420 pushes the movable rod A416 to slide to the outside of the cooling box 2 to reset, the connecting rod A417 and the slide rod 418 slide into the water outlet pipe 413, the slide rod 418 pushes the conical plug 419 to re-insert into the sealing ring 422 to close the water outlet pipe 413, the coolant stops circulating, and the one-way pressure valve automatically closes after the pressure drops, waiting for the next injection molding and cooling operation.
[0027] Example 2, as Figure 7 , Figure 8 As shown, based on Embodiment 1, the upper end of the moving rod A416 is fixedly connected to the connecting rod B51, the other end of the connecting rod B51 is fixedly connected to the moving rod B52, the other end of the moving rod B52 extends into the interior of the cooling box 2 and is fixedly connected to the inclined plate 55, the inner side of the inclined plate 55 is provided with an inclined groove 56, the bottom of the lower mold 31 is provided with a through hole, the interior of the through hole is slidably connected to the ejector rod 53, and the inner side of the ejector rod 53 is rotatably connected to the roller 54.
[0028] The end of the roller 54 furthest from the ejector rod 53 is slidably connected inside the inclined groove 56. There are four ejector rods 53, which are symmetrically arranged in pairs with the center line of the lower mold 31 as the axis. By sliding the roller 54 in the inclined groove 56, when the inclined plate 55 moves horizontally, it can push the roller 54 and the ejector rod 53 to slide up and down through the inclined surface of the inclined groove 56. This converts the horizontal movement of the inclined plate 55 into the vertical lifting and lowering movement of the ejector rod 53, realizing the automatic ejection of the injection molded part. The four ejector rods 53 are symmetrically distributed in pairs along the center line of the lower mold 31, so that the ejector rods 53 are evenly stressed when ejecting the injection molded part, avoiding deformation or damage to the injection molded part due to uneven stress, and ensuring the demolding quality and integrity of the injection molded part.
[0029] In practical use, when the moving rod A416 slides to the outside of the cooling box 2, the moving rod A416 drives the moving rod B52 to move to the outside of the cooling box 2 simultaneously through the connecting rod B51. The moving rod B52 drives the inclined plate 55 to move to the outside of the cooling box 2. When the inclined plate 55 moves to the outside, the inclined groove 56 on its inner side pushes the roller 54 to slide along the inclined surface of the inclined groove 56. The roller 54 drives the ejector rod 53 to slide upward along the through hole. The ejector rod 53 extends out from the inside of the lower mold 31 and ejects the cooled and molded swimming goggle injection part from the mold cavity of the lower mold 31 for easy removal. When the moving rod A416 slides towards the inside of the cooling box 2, the moving rod A416 drives the moving rod B52 and the inclined plate 55 to move towards the inside of the cooling box 2 through the connecting rod B51. The inclined groove 56 pushes the roller 54 to slide in the opposite direction along the inclined groove 56. The roller 54 drives the ejector rod 53 to slide down along the through hole to reset. The ejector rod 53 is retracted into the interior of the lower mold 31 to prepare for the next injection molding.
[0030] Example 3, as Figure 3 As shown, based on Embodiment 1, a stirring shaft 61 is rotatably connected to both sides of the protrusion of the bow-shaped plate 49, a stirring rod 62 is fixedly connected to the outer wall of the stirring shaft 61, a gear 63 is fixedly sleeved on the inner side of the stirring shaft 61 located in the protrusion of the bow-shaped plate 49, and a toothed plate 64 is fixedly connected to the outer wall of the moving rod A416.
[0031] The toothed plate 64 meshes with the gear 63. Multiple sets of stirring shafts 61 and stirring rods 62 are horizontally and equidistantly arranged on the outer side of the protrusion of the bow-shaped plate 49. By meshing the toothed plate 64 with the gear 63, the horizontal sliding of the moving rod A416 can drive the gear 63 and the stirring shaft 61 to rotate, converting the linear motion of the moving rod A416 into the rotational motion of the stirring rod 62. The stirring of the coolant can be completed without an additional power source.
[0032] When the above-mentioned equipment is used, when the moving rod A416 slides to the outside of the cooling box 2, the moving rod A416 drives the toothed plate 64 to move outward synchronously. The toothed plate 64 drives the gear 63 meshing with it to rotate. The gear 63 drives the stirring shaft 61 and the stirring rod 62 to rotate. The stirring rod 62 rotates outside the protrusion of the bow plate 49 to stir the coolant inside the cooling box 2, so that the coolant is evenly mixed inside the cooling box 2, avoiding temperature stratification of the coolant due to long-term stillness, and ensuring that the coolant temperature in each area inside the cooling box 2 is consistent. When the moving rod A416 slides to the inside of the cooling tank 2, the moving rod A416 drives the toothed plate 64 to move inward, the toothed plate 64 drives the gear 63 to rotate in the opposite direction, the stirring shaft 61 and the stirring rod 62 rotate in the opposite direction, and the coolant is stirred in the opposite direction to further improve the mixing uniformity of the coolant. By controlling the rotation of the stirring rod 62 through the sliding linkage of the moving rod A416, the coolant is continuously and uniformly stirred inside the cooling tank 2, so that the coolant always maintains a uniform temperature during the cooling process. This avoids the local temperature difference of the coolant affecting the cooling effect of the injection molded parts, and improves the consistency of cooling efficiency and injection molded part molding quality.

This narrative style is merely for clarity.
