Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to a multi-cavity synchronous demolding plastic mold. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to create shaped objects, primarily by changing the physical state of the material being molded to achieve the desired shape. They are often referred to as the "mother of industry."

[0003] Most existing plastic molds are not convenient for quick demolding and can only be used to injection mold multiple models at the same time, resulting in low production efficiency.

[0004] To address the aforementioned issues, a multi-cavity synchronous demolding plastic mold is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-cavity synchronous demolding plastic mold, which solves the problem that most existing plastic molds in the background art are inconvenient to demold quickly, and while they can be convenient to injection mold multiple models at the same time, they can only mold one at a time, resulting in low production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-cavity synchronous demolding plastic mold, including a lower mold base, a cavity inside the lower mold base, a lifting assembly inside the cavity, multiple top pillars connected to the top of the lifting assembly, multiple forming grooves on the top of the lower mold base, the top pillars penetrating the forming grooves, a vibration motor fixedly connected to the middle of the bottom of the lower mold base, an upper mold base on the top of the lower mold base, multiple sealing blocks fixedly connected to the bottom of the upper mold base, the sealing blocks corresponding to the forming grooves, mounting slots fixedly connected to both sides of the upper mold base, mounting seats fixedly connected to both sides of the lower mold base, each mounting seat having a limit groove on its top, a second bidirectional threaded rod penetrating and rotatably connected within the limit groove, clamping arms threaded to both sides of the outer ring of the second bidirectional threaded rod, the clamping arms being disposed on both sides of the mounting slots, a cooling pipe fixedly connected inside the lower mold base, a water tank located on the right rear of the lower mold base, a water pipe fixedly connected to the left side of the water tank, and a water pump fixedly connected to the end of the water pipe.

[0007] By adopting the above technical solution, the rotation of the second bidirectional threaded rod can drive the two clamping arms to move in opposite directions, thereby allowing the protrusions of the clamping arms to be pulled out from the grooves on both sides of the mounting slot, facilitating quick disassembly of the upper mold base.

[0009] By adopting the above technical solution, the lifting plate can be controlled to rise and fall in the cavity through the lifting component, thereby driving multiple top columns to pass through the molding groove at the same time, ejecting the molded plastic product, and realizing multi-cavity synchronous demolding.

[0010] As a further description of the above technical solution: the lower mold base is fixedly connected with evenly distributed springs at both the front and rear sides, and the bottom of the springs is fixedly connected with support seats.

[0011] By adopting the above technical solution, the spring has a certain strength and can play a supporting role for the lower mold base. The vibration generated by the vibration motor will cause the lower mold base to vibrate up and down under the action of the spring, reducing air bubbles in the material and making the material forming effect in the forming groove better.

[0012] As a further description of the above technical solution: the front end of the second bidirectional threaded rod is fixedly connected to a turntable, and the turntable is located on the outside of the mounting base.

[0013] By adopting the above technical solution, the turntable can drive the second bidirectional threaded rod to rotate.

[0014] As a further description of the above technical solution: the top of the upper mold base is provided with a feed port, and the feed port is connected to multiple sealing blocks.

[0015] By adopting the above technical solution, the feed port is connected to multiple sealing blocks through the channel in the upper mold base, which facilitates the filling of materials into multiple forming grooves at the top of the lower mold base.

[0016] As a further description of the above technical solution: the cooling pipe is disposed on the outer wall of the forming groove, and both ends of the cooling pipe penetrate the lower mold base.

[0021] By adopting the above technical solution, evenly distributed holes are opened on the outside of the knob and the turntable, so that the limiting pin can pass through the holes and be inserted into the groove on the outside of the lower mold base and the mounting base, thereby limiting the knob and the turntable and preventing the first bidirectional threaded rod and the second bidirectional threaded rod from loosening.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1-4This utility model discloses a multi-cavity synchronous demolding plastic mold, including a lower mold base 1, a cavity 2 inside the lower mold base 1, a lifting assembly inside the cavity 2, and multiple top posts 10 connected to the top of the lifting assembly. Multiple forming grooves 11 are formed on the top of the lower mold base 1, with the top posts 10 penetrating the forming grooves 11. The forming grooves 11 and the cavity 2 are connected by a through groove (not shown in the figure). The top posts 10 are positioned within the through groove, and during material forming, the top of the top posts 10 is flush with the inner wall of the forming groove 11 to avoid affecting material forming. A vibration motor 14 is fixedly connected to the bottom center of the lower mold base 1, enabling the lower mold base 1 to vibrate. An upper mold base 15 is provided on the top of the lower mold base 1, with multiple sealing blocks 16 fixedly connected to the bottom of the upper mold base 15. The sealing blocks 16 correspond to the forming grooves 11, facilitating their insertion into the forming grooves 11. Mounting slot blocks 18 are fixedly connected to both sides of the upper mold base 15, with grooves on both sides of the mounting slot blocks 18. Mounting seats 19 are fixedly connected to both sides of the lower mold base 1. Each mounting seat 19 has a limiting groove 20 on its top, which limits the clamping arms 22. A second bidirectional threaded rod 21 passes through and is rotatably connected within the limiting groove 20. Clamping arms 22 are threadedly connected to both sides of the outer ring of the second bidirectional threaded rod 21, and protrusions are provided on the outer side of the clamping arms 22. The clamping arms 22 are located on both sides of the mounting slot block 18. A cooling pipe 24, which is serpentine in shape, is fixedly connected inside the lower mold base 1. A water tank 26 is located on the rear right side of the lower mold base 1. An inlet pipe and a drain pipe are also provided on the outside of the water tank 26 for adding or draining water. A water pipe 27 is fixedly connected to the left side of the water tank 26, and a water pump 25 is fixedly connected to the end of the water pipe 27.

[0033] Reference Figure 2 The lifting assembly includes support blocks 3. The bottoms of two support blocks 3 are fixedly connected to the cavity 2. A first bidirectional threaded rod 4 is rotatably connected between the two support blocks 3. Movable frames 6 are threaded to both sides of the outer ring of the first bidirectional threaded rod 4. Support rods 7 are rotatably connected to both sides of the two movable frames 6. A lifting plate 8 is rotatably connected to the top of the support rod 7. The top of the lifting plate 8 is fixedly connected to the top column 10. Telescopic columns 9 are fixedly connected to the four corners of the bottom of the lifting plate 8, and the bottom of the telescopic columns 9 is fixedly connected to the cavity 2. The right side of the first bidirectional threaded rod 4 passes through the lower mold base 1. A knob 5 is fixedly connected to the right end of the first bidirectional threaded rod 4. The lifting assembly can control the lifting plate 8 to rise and fall in the cavity 2, thereby driving multiple top columns 10 to simultaneously pass through the molding groove 11 and eject the molded plastic product, realizing multi-cavity synchronous demolding.

[0034] Reference Figure 2 , Figure 3 and Figure 4The lower mold base 1 has evenly distributed springs 12 fixedly connected to both the front and rear sides of its bottom. A support base 13 is fixedly connected to the bottom of each spring 12. The springs 12 have sufficient strength to support the lower mold base 1. The vibration generated by the vibration motor 14 causes the lower mold base 1 to vibrate up and down under the action of the springs 12, reducing air bubbles in the material and improving the forming effect of the material in the forming groove 11. A turntable 23 is fixedly connected to the front end of the second bidirectional threaded rod 21, and the turntable 23 is located outside the mounting base 19. The turntable 23 drives the second bidirectional threaded rod 21 to rotate. Both the knob 5 and the turntable 23 have evenly distributed holes on their exteriors, allowing the limiting pin (not shown in the figure) to pass through the holes and be inserted into the grooves on the outside of the lower mold base 1 and the mounting base 19, thus limiting the knob 5 and the turntable 23 and preventing the first bidirectional threaded rod 4 and the second bidirectional threaded rod 21 from loosening. The upper mold base 15 has a feed inlet 17 at its top, which communicates with multiple sealing blocks 16. The feed inlet 17 communicates with the multiple sealing blocks 16 through a channel (not shown in the figure) inside the upper mold base 15, facilitating the filling of material into multiple forming grooves 11 at the top of the lower mold base 1. Cooling pipes 24 are installed on the outer wall of the forming grooves 11, and both ends of the cooling pipes 24 penetrate the lower mold base 1, facilitating the cooling of the material in the forming grooves 11. The outlet of the water pump 25 is fixedly connected to the left end of the cooling pipe 24 via a hose, and the water tank 26 is fixedly connected to the right end of the cooling pipe 24 via a hose.

[0035] Working principle: During installation, the upper mold base 15 is placed above the lower mold base 1, so that the sealing block 16 and the forming groove 11 are correspondingly engaged. Rotating the turntable 23 drives the second bidirectional threaded rod 21 to rotate. Since the outer ring of the second bidirectional threaded rod 21 is threaded with clamping arms 22 on both sides, and the clamping arms 22 are set on both sides of the mounting groove block 18, the clamping arms 22 will move towards each other in the limiting groove 20, so that the protrusions of the clamping arms 22 are inserted into the grooves on both sides of the mounting groove block 18. This achieves a fixed connection between the upper mold base 15 and the lower mold base 1. Molten plastic material is injected into the mold through the feed port 17 at the top of the upper mold base 15. The plastic material flows through the feed port 17 into the channel communicating with multiple sealing blocks 16, and then fills the multiple forming grooves 11 at the top of the lower mold base 1. At this time, the vibration motor 14 is started. The vibration generated by the vibration motor 14 will cause the lower mold base 1 to vibrate up and down under the action of the spring 12, which is used to eliminate air bubbles in the material in the forming groove 11, so as to improve the forming effect. Next, water pump 25 starts, drawing water from water tank 26 through water pipe 27 and delivering it via hose to the left side of cooling pipe 24. The water flows within the serpentine cooling pipe 24. Since the cooling pipe 24 is located on the outer wall of the molding tank 11, it cools the plastic material within the molding tank 11, allowing the plastic to solidify quickly. After flowing through the cooling pipe 24, the water flows back to water tank 26 from the right end of the cooling pipe 24 via hose, achieving circulating cooling. Finally, knob 5 is turned, causing the first bidirectional threaded rod 4 to rotate. Because both sides of the outer ring of the first bidirectional threaded rod 4 are threaded with movable frames 6, the two movable frames 6 will move towards or away from each other on the first bidirectional threaded rod 4. When the movable frames 6 move away from each other, the support rods 7 on both sides push the lifting plate 8 upwards. The lifting plate 8 causes multiple top columns 10 to rise, allowing the top columns 10 to penetrate the molding tank 11 and eject the molded plastic product.
