[0001] The present invention relates to the technical field of injection molds, and particularly to an environmentally friendly and crack-resistant elliptical flip cover forming mold. Background Art

[0002] With the development of modern industry, the application of molds is becoming more and more extensive. In products such as automobiles, household appliances, and daily necessities, about 60%-80% of the parts need to be processed and formed by molds. For example, in the production process of wet wipe box covers, multiple products can be formed at one time through molds, and the production efficiency is good. However, the existing molds still have deficiencies. On the one hand, most of the existing molds are eight-cavity molds, and the production and forming efficiency can no longer meet the requirements. On the other hand, after the processed molds and products need to be cooled, and the existing cooling method is usually to open cooling air ducts on the side of the mold to cool the mold, but this method is difficult to dissipate heat from the side opposite to the product and the mold. In addition, the existing molds usually need to be manually cleaned on the surface of the mold after processing, which is not only time-consuming and laborious but also easily poses unnecessary hidden dangers to the safety of the staff.

[0007] As a preference, the partition component includes a plugging block a slidably arranged in the guide groove and a chute a opened on the upper template. A chute b is opened at the tail end of the chute a. The chute b is communicated with the through hole.

[0008] As a preference, the ventilation component includes a connecting block arranged on the upper template and a ventilation pipeline opened inside the upper template. A ventilation hole is opened inside the connecting block. Both ends of the ventilation pipeline are respectively communicated with the ventilation hole and the air outlet.

[0013] As another preference, a connecting groove is provided on the lower template corresponding to the connecting block.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. During the mold closing process of the mold of the present invention, the surface of the mold can be automatically cleaned. When the mold is closed, the moving mold drives the guiding column to move towards the guiding groove. When the sealing ring on the guiding column fits with the guiding groove, the guiding groove is in a sealed state. During the continuous inward movement of the guiding column, the air in the guiding groove is compressed and the pressure becomes larger. When the ejector rod in the ejecting assembly pushes the plugging block a in the partitioning assembly backward to release the plugging of the air outlet in the guiding groove, the compressed air in the guiding groove is blown out from the air blowing hole a opened on the connecting block along the air pipe to clean the surface of the mold, avoiding the influence of residual impurities on the mold on the quality of the injection molded product, solving the problem that the existing technology mold still needs to be manually cleaned, which is not only time-consuming and laborious but also poses a certain safety hazard to the staff, and no additional power is required.

[0016] 2. During the mold opening process of the mold of the present invention, the effective heat dissipation of the side of the processed product opposite to the mold can be achieved through the cooperation of the guiding column and the ventilation assembly. When the mold is opened, during the process of the moving mold driving the guiding column to withdraw from the guiding groove, the guiding column realizes the suction effect through the movement of the sealing ring in the guiding groove, and can take away the hot air between the product and the mold through the air pipe, enabling the side of the product and the mold to cool faster and improving the processing and forming efficiency of the product, solving the problem that the cooling direction of the existing technology mold is relatively single and cannot effectively dissipate heat from the side of the product and the mold opposite to each other, affecting the forming efficiency of the product.

[0017] 3. The present invention is provided with a traction assembly. During mold opening, the sliding sleeve in the traction assembly moves backward synchronously with the moving mold. When the guiding column withdraws from the guiding groove, the sliding sleeve contacts the convex ring at the front end of the pull rod and then drives the pull rod to move outward. When the pull rod moves outward, the plugging block a is pushed outward by the convex block to close the air outlet, so that the guiding column can cooperate with the ventilation assembly to clean the surface of the mold again during the next mold closing, and the linkage effect of each component is good and the synchronization rate is good.

[0018] 4. When the mold is closed, the ejector rod abuts against the plugging block a and then slowly slides into the chute a. During this process, the ejector rod drives the plugging block b to move backward to open the air blowing hole b and draw air into the air cavity. When the mold is opened, the guide post withdraws from the guide groove, and the ejector rod drives the plugging block b to reset under the action of the return spring. The plugging block b blows the air in the air cavity out of the air blowing hole b to assist in cooling the surface of the product, further improving the molding efficiency of the product.

[0019] In summary, the present invention has the advantages of being able to automatically clean the surface of the mold, improving the molding efficiency of the product, faster heat dissipation on the surfaces of the product and the mold, and good linkage effect between components, and is suitable for the technical field of injection molds.

[0030] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings.

[0031] Embodiment 1

[0032] AsFigures 1 to 9As shown in the figure, an environmentally friendly anti-cracking elliptical flip cover forming mold includes a fixed mold 1 and a movable mold 2 that cooperates with the fixed mold 1. The fixed mold 1 includes an upper template 11 and a mounting plate 12. The movable mold 2 includes a lower template 21, a connecting plate 22, and a fixing plate 23. A material injection port 13 is provided on the fixed mold 1, a heat dissipation mechanism 3 is provided on the upper template 11, a driving mechanism 4 is provided on the lower template 21, a plurality of cavities 5 are formed on the upper template 11, and a core 6 corresponding to the cavity 5 is provided on the lower template 21. The heat dissipation mechanism 3 includes guiding grooves 31 opened at the four corners of the upper template 11, partition components 32 arranged in the guiding grooves 31, and a ventilation component 33 arranged on the upper template 11. The driving mechanism 7 includes guiding columns 41 arranged at the four corners of the lower template 21 corresponding to the guiding grooves 31, a pushing component 42 slidably arranged in the guiding columns 41, and a traction component 43 arranged on the lower template 21. When the fixed mold 1 and the movable mold 2 are clamped, the guiding columns 41 enter the guiding grooves 31 and fit with the guiding grooves 31. During the process of the guiding columns 41 entering the guiding grooves 31, the pushing component 42 drives the partition components 32 to open the ventilation component 33 to clean the surfaces of the upper template 11 and the lower template 21. During the process of the guiding columns 41 exiting the guiding grooves 31, the pushing component 42 cooperates with the ventilation component 33 to dissipate heat from the product and the mold. When the guiding columns 41 exit the guiding grooves 31, the traction component 43 drives the partition components 32 to close the ventilation component 33.When the fixed mold 1 and the moving mold 2 are clamped, the moving mold 2 drives the guide post 41 to move towards the guide groove 31. When the sealing ring 412 on the guide post 41 fits with the guide groove 31, the inside of the guide groove 31 is in a sealed state. During the process of the guide post 41 continuing to move inward, the air in the guide groove 31 is compressed and the pressure increases. When the ejector rod 420 in the ejecting assembly 42 pushes the plug block a320 in the partition assembly 32 backward, the plug block a320 releases the blockage of the air outlet 310 in the guide groove 31. Thus, the compressed air in the guide groove 31 is blown out from the air blowing hole a333 opened on the connecting block b330 along the air pipe 331 to clean the surfaces of the upper template 11 and the lower template 21, avoiding the influence of residual impurities on the mold on the quality of the injection-molded product. When the injection molding is completed and the fixed mold 1 and the moving mold 2 are opened, during the process of the moving mold 2 driving the guide post 41 to withdraw from the guide groove 31, the guide post 41 realizes the suction effect through the movement of the sealing ring 412 in the guide groove 31, taking away the hot air between the product and the mold through the air pipe 331. At the same time, the sliding sleeve 430 in the traction assembly 43 moves backward synchronously with the moving mold 2. When the guide post 41 withdraws from the guide groove 31, the sliding sleeve 430 contacts the convex ring 432 at the front end of the pull rod 431 and then drives the pull rod 431 to move outward. When the pull rod 431 moves outward, it pushes the plug block a320 outward through the convex block 434 to close the air outlet 310, enabling the guide post 41 to cooperate with the ventilation assembly 33 again to clean the mold surface during the next clamping, solving the problems in the prior art such as low production and forming efficiency, difficulty in dissipating heat on the side opposite to the product and the mold, and time-consuming and laborious mold surface cleaning method. There are 24 cavities 5 provided on the upper template 11, and 24 products can be formed at one time, greatly improving the production and forming efficiency.

[0033] As Figure 4 , Figure 5 and Figure 9 shown, an air outlet 310 is opened in the guide groove 31, a through hole 311 is opened at the tail end of the guide groove 31, and a groove 312 is opened at the front end of the guide groove 31. During clamping, the ejector rod 420 moves towards the guide groove 31 following the guide post 41, pushing the plug block a320 in the guide groove 31 backward to release the blockage of the air outlet 310 by the plug block a320. Thus, the guide post 41 blows out the compressed air in the guide groove 31 from the air blowing hole a333 opened on the connecting block b330 along the air pipe 331 to clean the surfaces of the upper template 11 and the lower template 21, avoiding the influence of residual impurities on the mold on the quality of the injection-molded product. Through the opened through hole 311, the pull rod 431 can push the plug block a320 through the convex block 434 to close the air outlet 310 during mold opening. Through the opened groove 312, the guide post 41 can fit more closely after entering the guide groove 31.

[0034] AsFigure 6 , Figure 7 , Figure 8 and Figure 9 As shown in Figure 6 , Figure 7 , Figure 8 and Figure 9 , the partition component 32 includes a plugging block a320 slidably arranged in the guiding groove 31 and a chute a321 formed on the upper template 11. A chute b322 is formed at the tail end of the chute a321, and the chute b322 is communicated with the through hole 311. When the mold is closed, the ejector rod 420 moves synchronously with the guiding column 41 to push the plugging block a320 backward, so that the plugging block a320 releases the plugging of the air outlet 310 in the guiding groove 31, and the compressed air in the guiding groove 31 can be blown out from the air outlet 310 under the extrusion of the guiding column 41. The chute a321 enables the pull rod 431 to be installed therein, and the movement of the pull rod 431 driven by the sliding sleeve 430 can be smoother and more stable. Through the chute b322, the connecting member b433 at the tail end of the pull rod 431 can move smoothly back and forth, and the width of the chute b322 is the same as that of the connecting member b433, which plays a role in limiting and stabilizing the pull rod 431 and the connecting member b433.

[0035] As Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in ,

[0035] , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the ventilation component 33 includes a connecting block b330 arranged on the upper template 11 and a ventilation pipeline 331 formed inside the upper template 11. A ventilation hole 332 is formed inside the connecting block b330. Both ends of the ventilation pipeline 331 are communicated with the ventilation hole 332 and the air outlet 310 respectively. A plurality of air blowing holes a333 are formed in a circular shape on the connecting block b330, and the air blowing holes a333 are communicated with the ventilation hole 332. When the mold is closed, the guiding column 41 squeezes the air in the guiding groove 31 into the ventilation pipeline 331 through the air outlet 310. The air enters the ventilation hole 332 through the ventilation pipeline 331 and is blown out from the air blowing holes a333 to clean the surface of the mold. A plurality of air blowing holes a333 are formed in a circular shape on the connecting block b330, which can clean the surface of the mold from multiple angles and in a larger range, and the cleaning effect is better. When the moving mold 2 drives the guiding column 41 to withdraw from the guiding groove 31 during mold opening, the guiding column 41 realizes the suction effect through the movement in the guiding groove 31 by means of the sealing ring 412, and can suck the hot air between the product and the mold from the air blowing holes a333 and take it away through the ventilation pipeline 331, so that the side of the product opposite to the mold can be cooled faster, and the efficiency of product processing and forming can be improved.

[0036] As Figure 3 and Figure 9As shown in the figure, a sliding groove c410 is formed in the guide post 41. A sealing ring 412 is provided at the front end of the guide post 41, and a connecting block a413 is provided at the tail end of the guide post 41 corresponding to the groove 312. When the sealing ring 412 on the guide post 41 fits with the guide groove 31, the guide groove 31 is in a sealed state. During the process of the guide post 41 continuing to move inward, the air in the guide groove 31 is compressed and the pressure increases. When the air outlet 310 is opened, the air can quickly blow out from the air outlet 310. When the moving mold 2 drives the guide post 41 to withdraw from the guide groove 31 during mold opening, the guide post 41 realizes the suction effect through the movement of the sealing ring 412 in the guide groove 31, and can take away the heat between the product and the mold. Through the formed sliding groove c410, the ejector rod 420 can move back and forth along the sliding groove c410 when the guide post 41 moves. By providing the connecting block a413 that cooperates with the groove 312, the guide post 41 can fit more tightly with the guide groove 31 after fitting.

[0037] As Figure 3 , Figure 6 , Figure 7 and Figure 9 shown, the ejector assembly 42 includes an ejector rod 420 slidably disposed in the sliding groove c410 and a return spring 421 fixedly disposed at the tail end of the ejector rod 420. When the mold is closed, the ejector rod 420 moves in the direction of the guide groove 31 following the guide post 41. During the movement of the guide post 41, the ejector rod 420 pushes the blocking block a320 backward to release the blocking of the air outlet 310 in the guide groove 31. When the mold is opened, during the process of the guide post 41 moving backward following the moving mold 2, the ejector rod 420 is reset along the sliding groove c410 under the action of the return spring 421; the ejector rod 420 abuts against the blocking block a320 after the guide post 41 enters the guide groove 31 for a certain distance. Before that, the guide post 41 makes the guide groove 31 in a sealed state through the sealing ring 412, so that the air in the guide groove 31 is compressed during the forward movement of the guide post 41, increasing the air pressure, so that the air can blow off impurities more powerfully when blowing out.

[0038] As Figure 3 , Figure 6 and Figure 9As shown in the figure, the traction assembly 43 includes a sliding sleeve 430 slidably disposed in the guiding groove 31 and a pull rod 431 slidably disposed in the sliding sleeve 430. The other end of the sliding sleeve 430 is fixedly connected to the lower template 21. The sliding sleeve 430 moves backward synchronously with the moving die 2. When the guiding post 41 exits the guiding groove 31, the sliding sleeve 430 contacts the convex ring 432 at the front end of the pull rod 431, thereby driving the pull rod 431 to move outward. The sliding sleeve 430 will drive the pull rod 431 to move outward and close the air outlet 310 through the plugging block a320 only after contacting the convex ring 432. Before that, the guiding post 41 can suck the hot air between the product and the mold through the ventilation pipeline 331, enter the guiding groove 31 from the air outlet 310, and then follow the guiding post 41 to discharge from the guiding groove 31.

[0039] As Figure 6 and Figure 9 shown in the figure, a convex ring 432 is provided at the front end of the pull rod 431, and a connecting member b433 is provided at the tail end of the pull rod 431. A convex block 434 is fixedly provided at the front end of the connecting member b433. The sliding sleeve 430 moves backward synchronously with the moving die 2. When the guiding post 41 exits the guiding groove 31, the sliding sleeve 430 contacts the convex ring 432 at the front end of the pull rod 431, thereby driving the pull rod 431 to move outward. When the pull rod 431 moves outward, the convex block 434 provided on the connecting member b433 at the tail end pushes the plugging block a320 outward to close the air outlet 310, so that the guiding post 41 can cooperate with the ventilation assembly 33 again to clean the mold surface during the next mold closing.

[0040] As Figure 2 shown in the figure, a connecting groove 24 is provided on the moving die 2 corresponding to the connecting block b330. Through the connecting groove 24, it can be attached to the connecting block b330 after mold closing, improving the tightness.

[0041] Embodiment Two

[0042] As Figure 3 , Figure 6 and Figure 8 shown in the figure, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below; the difference between this Embodiment Two and Embodiment One is that:

[0043] At the end of the sliding groove c410, a sliding groove d411 is provided. At the front end of the guiding column 41, an air cavity 414 is provided. A number of air blowing holes b415 are circumferentially provided at the top of the air cavity 414. During mold closing, when the ejector rod 420 abuts against the blocking block a320 and then slowly slides into the sliding groove a321, in this process, the ejector rod 420 drives the blocking block b423 provided on the connecting piece a422 to move backward to open the air blowing hole b415 and draw air into the air cavity 414. When the mold is opened, the guiding column 41 withdraws from the guiding groove 31, and the ejector rod 420 drives the blocking block b423 to reset under the action of the return spring 421. The blocking block b423 blows the air in the air cavity 414 out of the air blowing hole b415 to assist in cooling the surface of the product, further improving the molding efficiency of the product.

[0044] At the end of the ejector rod 420, a connecting piece a422 that cooperates with the sliding groove d411 is further provided. At the front end of the connecting piece a422, a blocking block b423 is fixedly provided. The size of the blocking block b423 fits the air cavity 414. During mold closing, when the ejector rod 420 abuts against the blocking block a320 and then slowly slides into the sliding groove a321, in this process, the ejector rod 420 drives the blocking block b423 to move backward to open the air blowing hole b415 and draw air into the air cavity 414. When the mold is opened, the guiding column 41 withdraws from the guiding groove 31, and the ejector rod 420 drives the blocking block b423 to reset under the action of the return spring 421. The blocking block b423 blows the air in the air cavity 414 out of the air blowing hole b415 to assist in cooling the surface of the product and then closes the air blowing hole b415 to prevent impurities from falling into the air cavity 414 during subsequent mold cleaning.
