Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and particularly to a layered injection mold capable of quickly cooling down. Background Art

[0002] Injection molds are usually equipped with heating elements, such as electric heating coils or heating rods. These heating elements provide heat to the injection mold during the injection process to ensure that the injection mold reaches and maintains the required working temperature. Usually, a cooling system is provided in the injection mold. The cooling system achieves this purpose by arranging cooling water channels or cooling channels inside the injection mold. The coolant circulates in the cooling system, absorbs the heat in the injection mold and the injection molded part, and then takes it to the outside for heat dissipation. This can accelerate the cooling speed of the injection molded part, shorten the production cycle, and help reduce the internal stress and deformation of the injection molded part.

[0003] To ensure the cooling requirements, mechanical strength, and durability of the injection molded part, a thicker injection mold can provide better thermal stability and cooling effect, which helps to ensure uniform cooling of the plastic part during the injection process and reduce defects caused by temperature differences. Secondly, a thick injection mold usually has higher mechanical strength and durability and can withstand the pressure and impact generated during the injection process.

[0004] When cooling the injection molded part, usually the injection mold is cooled. After cooling is completed, the injection mold needs to be heated again to ensure the fluidity of the plastic melt. However, since the volume of the injection mold is usually large, the cooling time will be relatively long. At the same time, when reheating the injection mold, the heating elements need to emit a relatively large amount of heat, resulting in high energy consumption. Summary of the Invention

[0005] In order to overcome the drawback that when reheating the injection mold, the heating elements need to emit a relatively large amount of heat, resulting in high energy consumption, the present invention provides a layered injection mold capable of quickly cooling down.

Only the male mold and the female mold need to be heated, thus saving energy.

[0015] 2. By controlling the shortening of the telescopic rod of the hydraulic cylinder three, the female mold can be driven to move leftward, so that the female mold and the movable mold base are recombined. Subsequently, the ejection frame will be inserted into the through hole on the female mold to eject the injection molded part within the female mold, facilitating material taking.

At the front ends of the second horizontal slide bars 111, there are second sealing covers 12 connected. On the rear side of the convex mold 3 and the rear side of the concave mold 8, there are two second springs 13 connected. The front ends of the second springs 13 are connected to the rear sides of the second sealing covers 12. The second springs 13 are sleeved on the second horizontal slide bars 111. On the upper part of the front side of the first sealing covers 10, there are water inlet pipes 14 communicated. On the lower part of the rear side of the second sealing covers 12, there are water outlet pipes 15 communicated. The docking mechanism is used to dock the first sealing cover 10 and the second sealing cover 12, cover one side of the convex mold 3 and the concave mold 8 to form a sealed space, and inject coolant into this sealed space to be able to cool down the convex mold 3 and the concave mold 8. The plugging mechanism is used to block the injection hole 4 on the convex mold 3.

[0033] Refer to Figures 4-6 , The docking mechanism includes a mounting frame 16, a cylinder 17, a lifting plate 18 and a pressing plate 19. On the top of the frame 1, there is a mounting frame 16 connected. In the middle of the top of the mounting frame 16, there is a cylinder 17 connected. The lower end of the telescopic rod of the cylinder 17 is connected to the lifting plate 18. At the front and back sides of the bottom of the lifting plate 18, there are pressing plates 19 connected.

[0034] Refer to Figure 7, the plugging mechanism includes a plugging block 20, a first contact plate 21, a third spring 22 and a first push plate 23. The plugging block 20 is slidably connected to the right side of the second sealing cover 12 on the punch 3. The right end of the plugging block 20 is connected to the first contact plate 21. The third spring 22 is connected to the right side of the second sealing cover 12 on the punch 3. The right end of the third spring 22 is connected to the left side of the first contact plate 21. The third spring 22 is sleeved on the plugging block 20. The middle part of the right side of the lifting plate 18 is connected to the first push plate 23.

[0035] Referring to Figure 13 and Figure 14 , it further includes a positioning shaft 31. Two positioning shafts 31 are connected to the upper and lower sides of the right side of the female die 8 respectively. Two positioning grooves 32 are formed on the upper and lower sides of the left side of the punch 3.

[0036] Referring to Figure 4 , it further includes a vertical sliding rod 34. The front and rear sides of the top of the mounting frame 16 are slidably connected to the vertical sliding rod 34. The lower end of the vertical sliding rod 34 is connected to the top of the lifting plate 18.

[0037] The staff controls the telescopic rod of the second hydraulic cylinder 7 to extend, driving the moving die holder 6 and the female die 8 to move towards the male die 3, performing mold closing. The positioning shaft 31 can be inserted into the positioning groove 32 for positioning. Then, the injection liquid is injected between the male die 3 and the female die 8 through the injection hole 4. Next, the fixed die holder 2, the male die 3, the moving die holder 6, and the female die 8 are heated for injection molding. After the injection molding is completed, the staff controls the telescopic rod of the second hydraulic cylinder 7 to shorten, driving the moving die holder 6 and the female die 8 to move leftward. At the same time, the staff controls the telescopic rod of the first hydraulic cylinder 5 to extend, driving the male die 3 to move leftward. The male die 3 separates from the fixed die holder 2, and the male die 3 and the female die 8 move leftward synchronously. When the male die 3 and the female die 8 move to directly below the lifting plate 18, the first hydraulic cylinder 5 is closed to stop the male die 3 from moving leftward. At this time, the telescopic rod of the second hydraulic cylinder 7 continues to shorten, and the moving die holder 6 and the third hydraulic cylinder 9 continue to move leftward. At the same time, the staff controls the telescopic rod of the third hydraulic cylinder 9 to extend, enabling the female die 8 to remain stationary, and the female die 8 separates from the moving die holder 6. Then, the staff controls the telescopic rod of the cylinder 17 to extend, driving the lifting plate 18 and the pressing plate 19 to move downward. The pressing plate 19 will press the first horizontal slide bar 91 and the second horizontal slide bar 111, causing the first sealing cover 10 and the second sealing cover 12 to move towards each other, making the first sealing cover 10 and the second sealing cover 12 dock and covering one side of the male die 3 and the female die 8 to form a sealed space. The first spring 11 and the second spring 13 are stretched. At this time, the blocking block 20 corresponds to the injection hole 4 on the male die 3. The downward movement of the lifting plate 18 can also drive the first push plate 23 to move downward. The first push plate 23 pushes the first contact plate 21 to move leftward, compressing the third spring 22. The first contact plate 21 drives the blocking block 20 to move leftward, and the blocking block 20 can be inserted into the injection hole 4 on the male die 3 to block the injection hole 4 on the male die 3, preventing the leakage of the coolant. The coolant is injected into this sealed space through the water inlet pipe 14 to cool the male die 3 and the female die 8. The male die 3 has separated from the fixed die holder 2, the female die 8 has separated from the moving die holder 6, and the male die 3 and the female die 8 are relatively thin, so that the male die 3 and the female die 8 can be cooled quickly, and then the injection molded part between the male die 3 and the female die 8 can be cooled quickly. After the injection molded part is cooled, the staff controls the telescopic rod of the cylinder 17 to shorten, driving the lifting plate 18, the pressing plate 19, and the first push plate 23 to move upward. The vertical slide bar 34 can guide the lifting plate 18 to make the movement of the lifting plate 18 more stable. The pressing plate 19 no longer presses the first horizontal slide bar 91 and the second horizontal slide bar 111. Under the action of the first spring 11 and the second spring 13, the first sealing cover 10 and the second sealing cover 12 move away from each other, separating the first sealing cover 10 and the second sealing cover 12. The first push plate 23 no longer pushes the first contact plate 21. Under the action of the third spring 22, the blocking block 20 moves rightward, and the blocking block 20 moves out of the injection hole 4 on the male die 3. Then, the staff controls the telescopic rod of the first hydraulic cylinder 5 to shorten, driving the male die 3 to move rightward to recombine the male die 3 and the fixed die holder 2. Subsequently, the staff controls the telescopic rod of the third hydraulic cylinder 9 to shorten, driving the female die 8 to move leftward.Recombine the female mold 8 and the moving mold base 6. Since the male mold 3 and the female mold 8 are cooled separately, the fixed mold base 2 and the moving mold base 6 are still in a high-temperature state. Only the male mold 3 and the female mold 8 need to be heated, thus saving energy.

[0038] Embodiment 2: On the basis of Embodiment 1, referring to Figures 8-12 , it further includes an ejection mechanism. The ejection mechanism includes an ejection frame 24, a fourth spring 25, a blocking frame 26 and a plugging component. The left side of the moving mold base 6 is slidably connected with the ejection frame 24. Five through holes adapted to the ejection frame 24 are opened on the female mold 8. The ejection frame 24 is located in the through holes. Two fourth springs 25 are sleeved on the upper and lower parts of the ejection frame 24 respectively. The two ends of the fourth spring 25 are connected with the moving mold base 6 and the ejection frame 24 respectively. The middle part of the left side in the frame 1 is connected with the blocking frame 26. The plugging component is used to block the through holes on the female mold 8.

[0039] Referring to Figures 10-12 , the plugging component includes a plugging rod 27, a second contact plate 28, a fifth spring 29 and a second push plate 30. Two plugging rods 27 are slidably connected to the left side of the first sealing cover 10 on the female mold 8. Three plugging rods 27 are slidably connected to the left side of the second sealing cover 12 on the female mold 8. The left ends of the two plugging rods 27 on the first sealing cover 10 on the female mold 8 are jointly connected with the second contact plate 28. The left ends of the three plugging rods 27 on the second sealing cover 12 on the female mold 8 are also jointly connected with the second contact plate 28. Two fifth springs 29 are connected to the left side of the first sealing cover 10 on the female mold 8. Three fifth springs 29 are connected to the left side of the second sealing cover 12 on the female mold 8. The left end of the fifth spring 29 is connected with the right side of the second contact plate 28. The fifth spring 29 is sleeved on the plugging rod 27. The middle part of the left side of the lifting plate 18 is connected with the second push plate 30.

[0040] Referring to Figure 9 , it further includes a limiting plate 33. Limiting plates 33 are connected to the upper and lower sides of the left side of the moving mold base 6.

[0041] When the punch 3 and the die 8 are closed, the limit plate 33 can limit the ejection frame 24, enabling the ejection frame 24 to fill the through holes on the die 8, preventing the injection liquid from flowing into the through holes on the die 8. When the first sealing cover 10 and the second sealing cover 12 are butted, the two contact plates II 28 will also be butted. The plugging rod 27 corresponds to the through holes on the die 8. When the lifting plate 18 moves downward, the second push plate 30 will also move downward. The second push plate 30 will push the contact plate II 28 to move to the right, compressing the fifth spring 29. The contact plate II 28 drives the plugging rod 27 to move to the right, and the plugging rod 27 will insert into the through holes on the die 8 to block the through holes on the die 8, preventing the coolant from leaking. After the injection molding part is cooled, the injection molding part will remain in the die 8. Control the telescopic rod of the second hydraulic cylinder 7 to shorten, driving the moving die base 6 and the ejection frame 24 to move to the left. When the ejection frame 24 moves to the left and contacts the blocking frame 26, the blocking frame 26 blocks the ejection frame 24, causing the ejection frame 24 to move to the right relative to the moving die base 6, compressing the fourth spring 25. Subsequently, control the telescopic rod of the third hydraulic cylinder 9 to shorten, driving the die 8 to move to the left to recombine the die 8 and the moving die base 6. At this time, the ejection frame 24 will insert into the through holes on the die 8 to eject the injection molding part in the die 8, facilitating material taking.

The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
