Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a novel injection mold. Background Technology

[0002] Injection molds are tools used in the injection molding process to inject molten plastic material under high pressure into a mold cavity, where it is then cooled and solidified to obtain the finished product. Injection molds are widely used in industrial fields, especially in the automotive, electronics, home appliance, and toy industries.

[0003] During the use of injection molds, the plastic material is completely melted by stirring with a screw and injected into the mold cavity under high pressure. After cooling and solidification, the molded product is obtained. However, due to the good fluidity of the molten plastic material, if the fit between the moving mold and the stationary mold is not tight enough, the molten plastic can easily overflow from the gap between the contact surfaces of the moving mold and the stationary mold during the injection process. After cooling, it forms unwanted plastic flakes or edges, resulting in the problem of overflow in injection molded products. Overflow not only affects the appearance quality of the product, but also reduces its mechanical properties and sealing performance. Utility Model Content

[0004] To address the technical problem that molten plastic easily overflows from the gap between the moving and stationary molds during injection molding, forming unwanted plastic flakes or edges after cooling, which not only affects the appearance quality of the product but also reduces its mechanical and sealing properties, this invention provides a novel injection mold.

[0005] The technical solution adopted by this utility model is as follows: A workbench is included, a first mounting plate is fixedly connected to the workbench, a stationary mold is fixedly mounted on the first mounting plate, an injection hole is provided on the stationary mold, a moving mold is provided on one side of the stationary mold, a second mounting plate is fixedly mounted on the workbench, a driving cylinder is fixedly mounted on one side of the second mounting plate, a connecting plate is fixedly connected to the piston rod of the driving cylinder, a connecting rod is fixedly mounted on the side of the connecting plate away from the second mounting plate, one end of the connecting rod is fixedly connected to the moving mold, locking blocks are fixedly mounted on both the upper and lower ends of the moving mold, a slot is provided on one side of the first mounting plate, the slot is adapted to the locking block, and a locking mechanism is provided on the first mounting plate.

[0006] Furthermore, the locking mechanism includes a mounting groove in the first mounting plate, a locking rod slidably mounted in the mounting groove, and a locking hole in the locking block. The locking rod is adapted to the locking hole, and a second spring is fixedly installed inside the mounting groove. One end of the second spring is fixedly connected to one side of the locking rod.

[0007] By adopting the above technical solution, the static mold and the moving mold fit together tightly, reducing the occurrence of overflow.

[0008] Furthermore, the first mounting plate is provided with a sliding groove, which is connected to the interior of the mounting groove. A push plate is slidably installed in the sliding groove, and the push plate is fixedly connected to the locking rod.

[0009] By adopting the above technical solution, the locking between the static mold and the moving mold can be released.

[0010] Furthermore, an installation block is fixedly installed on the first mounting plate, and an electric telescopic rod is fixedly installed on the installation block, with one end of the electric telescopic rod fixedly connected to the push plate.

[0011] By adopting the above technical solution, it is more convenient to release the locking between the static mold and the moving mold.

[0012] Furthermore, a sliding plate is slidably sleeved on the outside of the connecting rod, a through hole is opened on the moving mold, a push rod is slidably installed in the through hole, the push rod is slidably connected to the sliding plate, a first spring is sleeved on the outside of the push rod, the first spring is fixedly installed between the sliding plate and the moving mold, and a stop block is fixedly installed on one side of the second mounting plate.

[0014] Furthermore, both the first mounting plate and the stationary mold are provided with guide holes, and a guide rod is slidably installed in the guide holes, with one end of the guide rod being fixedly connected to the moving mold.

[0015] By adopting the above technical solutions, the stability of the moving mold during movement is improved.

[0016] The beneficial effects of this utility model are: by using the moving mold in conjunction with the first mounting plate, locking block, locking rod and second spring, the moving mold and the stationary mold are tightly fitted after contact, reducing the gap between the moving mold and the stationary mold. The molten plastic material is difficult to overflow from the gap between the contact surfaces of the stationary mold and the moving mold, thereby avoiding the formation of unnecessary plastic flakes or edges around the product after cooling, reducing the occurrence of overflow, which is conducive to improving the appearance quality of the product and ensuring the mechanical and sealing performance of the product.

[0017] By using a connecting plate in conjunction with a sliding plate, connecting rod, push rod, first spring, and through holes on the moving mold, the push rod automatically ejects the cooled injection molded product from the moving mold during the separation process between the moving mold and the stationary mold. This eliminates the need for manual removal of the injection molded product from the moving mold, reduces the workload of workers, facilitates continuous use of the device, and ultimately improves the production efficiency of injection molded products.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0027] To address the problems existing in the background art, this application proposes the following technical solution: A workbench 1 is included, on which a first mounting plate 2 is fixedly connected. The first mounting plate 2 provides installation conditions for a stationary mold 3. The stationary mold 3 is fixedly mounted on the first mounting plate 2, and an injection hole 14 is opened on the stationary mold 3. A moving mold 4 is provided on one side of the stationary mold 3. A second mounting plate 5 is fixedly mounted on the workbench 1. A drive cylinder 6 is fixedly mounted on one side of the second mounting plate 5. The piston rod of the drive cylinder 6 passes through the second mounting plate 5 and is slidably connected to the second mounting plate 5. A connecting plate 7 is fixedly connected to the piston rod of the drive cylinder 6. A connecting rod 9 is fixedly mounted on the side of the connecting plate 7 away from the second mounting plate 5. One end of the connecting rod 9 is fixedly connected to the moving mold 4. Locking blocks 15 are fixedly mounted on both the upper and lower ends of the moving mold 4. A slot 26 is opened on one side of the first mounting plate 2, and the slot 26 is adapted to the locking block 15. A locking mechanism is provided on the first mounting plate 2.

[0028] The piston rod of the drive cylinder 6 drives the connecting plate 7 to move. The connecting plate 7 drives the moving mold 4 to move through the connecting rod 9, so that the moving mold 4 and the stationary mold 3 can fit together and separate. When the drive cylinder 6 is in motion, the moving mold 4 and the stationary mold 3 are in contact. At this time, the locking block 15 is inserted into the slot 26, and the locking mechanism locks the locking block 15 in the slot 26, so that the moving mold 4 and the stationary mold 3 are tightly fitted together. The external injection equipment injects molten plastic material into the mold cavity between the stationary mold 3 and the moving mold 4 through the injection hole 14. Because the moving mold 4 and the stationary mold 3 are tightly fitted together, the molten plastic material is difficult to overflow from the gap between the contact surfaces of the stationary mold 3 and the moving mold 4, thereby avoiding the formation of unnecessary plastic flakes or edges around the product after cooling, reducing the occurrence of overflow, which is beneficial to improving the appearance quality of the product and ensuring the mechanical and sealing performance of the product.

[0029] To further explain, the locking mechanism includes a mounting groove 17 formed in the first mounting plate 2, a locking rod 18 slidably mounted in the mounting groove 17, and a locking hole 16 formed on the locking block 15. The locking rod 18 is adapted to the locking hole 16. A second spring 19 is fixedly installed inside the mounting groove 17, and one end of the second spring 19 is fixedly connected to one side of the locking rod 18.

[0030] During the process of the moving mold 4 and the stationary mold 3 fitting together, the locking block 15 is inserted into the slot 26. One end of the locking block 15 is set with a ramp. The ramp contacts and presses the locking rod 18, causing the locking rod 18 to move upward and compressing the second spring 19. After the moving mold 4 and the stationary mold 3 are fully fitted together, the locking hole 16 moves below the locking rod 18. The compressed second spring 19 pushes the locking rod 18 downward to the locking hole 16 to restore its initial state. The locking rod 18 cooperates with the locking hole 16 to limit the locking block 15, so that the locking block 15 is locked in the slot 26, thereby tightly fitting the moving mold 4 and the stationary mold 3 together, reducing the gap between the contact surfaces of the moving mold 4 and the stationary mold 3, and avoiding overflow.

[0031] Furthermore, the first mounting plate 2 is provided with a sliding groove 23, which is connected to the interior of the mounting groove 17. A push plate 20 is slidably installed in the sliding groove 23, and the push plate 20 is fixedly connected to the locking rod 18.

[0032] After the molten plastic material is injected and cooled, the push plate 20 is pushed away from the moving mold 4. The push plate 20 drives the locking rod 18 to move, so that the locking rod 18 is moved out of the slot 26, releasing the lock between the moving mold 4 and the stationary mold 3. At this time, the drive cylinder 6 drives the moving mold 4 to move away from the stationary mold 3, so that the cooled injection molded product can be taken out. The setting of the push plate 20 can release the lock between the moving mold 4 and the stationary mold 3, making it easy to take out the injection molded product.

[0033] To further explain, an installation block 21 is fixedly installed on the first installation plate 2, and an electric telescopic rod 22 is fixedly installed on the installation block 21. One end of the electric telescopic rod 22 is fixedly connected to the push plate 20.

[0034] Mounting block 21 provides installation conditions for electric telescopic rod 22. The free end of electric telescopic rod 22 is connected to push plate 20. The electric telescopic rod 22 pulls push plate 20 to move, thereby releasing the locking between mold 4 and stationary mold 3. The electric telescopic rod 22 improves the ease of use of the device and also helps to improve the automation of the device, thereby improving the production efficiency of injection molded products.

[0035] Furthermore, the connecting rod 9 is externally slidably fitted with a slide plate 8, the moving mold 4 has a through hole 25, a push rod 10 is slidably installed in the through hole 25, the push rod 10 is slidably connected to the slide plate 8, the push rod 10 is externally fitted with a first spring 12, the first spring 12 is fixedly installed between the slide plate 8 and the moving mold 4, and a stop block 11 is fixedly installed on one side of the second mounting plate 5.

[0036] The right end of the ejector rod 10 is located in the through hole 25. During the injection molding process, the right end of the ejector rod 10 blocks the through hole 25 to prevent the molten plastic material from flowing out of the through hole 25 during injection. After the molten plastic material is injected and completely cooled, the piston rod of the drive cylinder 6 drives the connecting plate 7 to move to the left. The connecting plate 7 drives the moving mold 4 to move to the left through the connecting rod 9. The moving mold 4 drives the slide plate 8 to move to the left through the first spring 12. The slide plate 8 drives the ejector rod 10 to move to the left. When the left end of the ejector rod 10 contacts the stop block 11, the stop block 11 prevents the ejector rod 10 from moving to the left, so that the ejector rod 10 relative to the stop block 11 moves to the left. The moving mold 4 moves to the right, and the right end of the push rod 10 extends out of the through hole 25 to eject the cooled injection molded product inside the moving mold 4, thus completing the removal of the injection molded product. This avoids the need for manual removal of the injection molded product from the moving mold 4, reducing the labor intensity of workers and improving production efficiency. At the same time, the push rod 10 drives the slide plate 8 to move to the right, and the slide plate 8 compresses the first spring 12. After the product is removed, when the piston rod of the drive cylinder 6 pushes the moving mold 4 to move to the right, the compressed first spring 12 pushes the slide plate 8 back to its initial position to restore its initial state, which facilitates continuous use of the device and improves the practicality of the device.

[0037] Furthermore, both the first mounting plate 2 and the stationary mold 3 are provided with guide holes 24, and guide rods 13 are slidably installed in the guide holes 24. One end of the guide rods 13 is fixedly connected to the moving mold 4.

[0038] The guide rod 13, in conjunction with the guide hole 24, guides and limits the movement of the moving mold 4, improving the stability of the moving mold 4 during the bonding and separation process with the stationary mold 3, and ensuring the stable operation of the device.

[0039] The specific operation is as follows: The piston rod of the drive cylinder 6 drives the connecting plate 7 to move. The connecting plate 7 drives the moving mold 4 to move through the connecting rod 9, so that the moving mold 4 fits with the stationary mold 3. The locking block 15 is inserted into the slot 26. The locking block 15 contacts and presses against the locking rod 18, causing the locking rod 18 to move upward and the second spring 19 to compress. After the moving mold 4 and the stationary mold 3 are fully fitted, the locking hole 16 moves below the locking rod 18. The compressed second spring 19 pushes the locking rod 18 downward into the locking hole 16. The locking rod 18 cooperates with the locking hole 16 to limit the locking block 15, so that the locking block 15... Locked in slot 26, the moving mold 4 and the stationary mold 3 are tightly fitted together. The external injection equipment injects molten plastic material into the mold cavity between the stationary mold 3 and the moving mold 4 through injection hole 14. After the molten plastic material in the mold cavity has completely cooled, the electric telescopic rod 22 is activated. The electric telescopic rod 22 pulls the push plate 20 to move and release the locking between the mold 4 and the stationary mold 3. The piston rod of the drive cylinder 6 drives the moving mold 4 to move to the left. The left end of the push rod 10 contacts the stop block 11, and the right end of the push rod 10 extends out from the through hole 25 to push out the cooled injection molded product inside the moving mold 4, completing the removal of the injection molded product.
