Description

Technical Field

[0001] The present application relates to the technical field of injection molds, and in particular to a continuous molding mold for injection molded parts. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. It mainly forms a mold cavity by the cooperation of a die and a punch, and then opens a flow channel on the die or the punch to connect to the mold cavity. Plastic fluid is injected into the mold cavity through the flow channel so that the plastic fluid fills the mold cavity, and then the plastic fluid is cooled to form an injection molded part.

[0003] In a continuous molding injection mold, a plurality of components cooperating with each other are provided on the female mold and the male mold, so that one mold has multiple mold cavities, so that one mold can continuously inject multiple plastic parts. However, if multiple mold cavities are injection molded by setting multiple separate flow channels, it will result in the need to set multiple injection molding devices on the female mold or the male mold with the flow channels. Multiple injection molding devices occupy too much space and cannot be all set on the female mold or the male mold. In order to solve this technical problem, the prior art provides a flow channel connecting each casting cavity on the female mold, and connects the injection molding device to the male mold. When the male mold and the female mold are closed, the output end of the male mold extends into the casting cavity of the female mold to form multiple mold cavities. The injection molding device injects the plastic fluid into the flow channel of the female mold through the male mold, and the plastic fluid flows along the flow channel to each mold cavity, so that one injection molding device can perform injection molding on multiple mold cavities.

[0004] However, after the injection molding is completed, the plastic fluid remaining in the mold flow channel will form a connecting frame connecting the various plastic parts during demolding. This means that when the plastic parts are needed later, they need to be separated from the connecting frame, so that the processed plastic parts need to be processed later. The increase in processing steps also increases the workload of the staff. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a continuous molding mold for injection molded parts, which is used to solve the technical problem in the prior art that the plastic fluid in the die flow channel increases the processing steps and increases the workload of the staff.

[0006] The above-mentioned purpose of the present application is achieved through the following technical scheme: a continuous molding mold for injection molded parts, including a movable mold base, a concave mold arranged on the movable mold base, a fixed mold base arranged on a side of the concave mold away from the movable mold base, and a convex mold arranged on the fixed mold base, the concave mold is provided with a plurality of casting cavities, and a flow channel connecting each casting cavity, the convex mold is provided with a plurality of output ends for matching the casting cavities, the movable mold base and the concave mold are both provided with a partial breaking component, the breaking component includes a plurality of clamping columns respectively arranged on the connection parts connecting the plurality of casting cavities on the flow channel, a plurality of push rods arranged on the movable mold base, and a driving cylinder arranged on the movable mold base and connected to the bottom surface of the concave mold at the output end, the casting cavity of the concave mold passes through the bottom surface of the concave mold, the end of the push rod away from the movable mold base extends into the casting cavity, and the clamping column is T-shaped and does not extend out of the flow channel.

[0007] By adopting the above technical solution, the push rod occupies most of the space in the casting cavity when the female mold is not closed. When the mold is closed, the female mold is moved closer to the male mold by starting the driving cylinder, and the push rod gradually moves down in the casting cavity so that the space in the casting cavity is sufficient to form a plastic part. When the injection molding device injects the plastic fluid into the flow channel of the female mold through the male mold, the plastic fluid flows along the flow channel to each mold cavity, and the flowing plastic fluid wraps the clamping column. When the injection molding is completed and the mold is demolded, the plastic fluid remaining on the flow channel of the female mold will form a connecting frame connecting each plastic part, and the connecting frame connects the connection points of the plastic parts. The clamping column is wrapped around the connecting frame, and during the demoulding process, the push rod gradually moves up in the casting cavity to push the plastic part out of the casting cavity. At this time, since the connecting frame is stuck by the clamping column and the clamping column is located at the connection between the connecting frame and the plastic part, the connection between the connecting frame and the plastic part will be subjected to tension and break, causing the connecting frame to remain on the die and separate from the plastic part, so that the staff does not need to process the completed plastic part again, reducing the processing steps and the workload of the staff, making it easier for the staff to process the plastic parts, and the connecting frame retained on the die only needs to be removed from the die.

[0008] Furthermore, a fixing block with a triangular cross section is provided on one side of the clamping column close to the casting cavity. The fixing block is fixedly connected to the die and located in the flow channel, and the inclined surface of the fixing block faces the casting cavity.

[0009] By adopting the above technical solution, although the setting of the breaking component makes it easier for the staff to process the plastic parts, when the push rod gradually moves up in the casting cavity and pushes the plastic part out of the casting cavity, since the connecting frame and the plastic part are integrally formed, this may cause the connecting frame to pull the part of the plastic part close to the connecting frame when it breaks, causing damage to the plastic part. The setting of the fixed block solves this technical problem. When the plastic fluid flows along the flow channel into each mold cavity, the flowing plastic fluid will wrap the fixed block. When the injection molding is completed and the mold is demolded, the plastic fluid remaining on the flow channel of the die will form a connecting frame connecting the various plastic parts. Because of the setting of the fixed block, a triangular notch will be formed at the connection between the connecting frame and the plastic part. This notch makes it easier for the connecting frame to break after being subjected to tension when the push rod gradually moves up in the casting cavity and pushes the plastic part out of the casting cavity. This notch can prevent the connecting frame from pulling the part of the plastic part close to the connecting frame to break together, thereby reducing the scrap rate during processing.

[0010] Furthermore, the punch is provided with a protective component to prevent the plastic part from being sleeved on the output end of the punch.

[0011] Furthermore, the protection component includes a top ring sleeved on the output end of the punch and a top spring arranged on the punch for pushing the top ring to move toward the die, one end of the top spring is fixedly connected to the top ring, and the other end is fixedly connected to the punch.

[0012] By adopting the above technical solution, although the setting of the fixed block can prevent the connecting frame from pulling the part of the plastic part close to the connecting frame to break together, and reduce the scrap rate in the processing process, the connecting frame is more likely to break, and the push rod will push the plastic part off the connecting frame and then sleeve it on the output end of the punch, so that the staff needs to remove the plastic parts from the output end of the punch one by one, which is very inconvenient. The setting of the protective component solves this technical problem. When the plastic part is sleeved on the output end of the punch, the top spring will push the top ring, so that the top ring pushes the plastic part off the punch, preventing the plastic part from getting stuck on the punch and increasing the workload of the staff.

[0013] Furthermore, a rubber sleeve is provided at one end of the push rod extending into the casting cavity. The rubber sleeve is elastic and has a transition fit with the casting cavity.

[0014] By adopting the above technical solution, the rubber sleeve that transitionally matches the casting cavity can prevent the leakage of plastic fluid.

[0015] Furthermore, the rubber sleeve is threadedly connected to the push rod.

[0016] By adopting the above technical solution, the rubber sleeve threadedly connected to the push rod is easy to replace by the staff.

[0017] Furthermore, the push rod is threadedly connected to the movable mold base.

[0018] By adopting the above technical solution, the push rod is threadedly connected to the movable mold base, so that the staff can easily replace the push rod.

[0019] Furthermore, a disengagement ejector column is provided on the movable mold base, one end of which is connected to the movable mold base, and the other end passes through the concave mold and extends into the flow channel. The disengagement ejector column is located in the middle of the connection between two opposite connecting casting cavities of the flow channel.

[0020] By adopting the above technical solution, although the setting of the breaking component makes it easier for the staff to process the plastic parts, it also requires the staff to use a very large force to remove the connecting frame from the die. The setting of the disengagement push post solves this technical problem. When the mold is closed, the disengagement push post is flush with the bottom surface of the flow channel, so that the plastic fluid can flow normally in the flow channel. When demolding, due to the lowering of the die, the disengagement push post gradually extends out of the flow channel and pushes the connecting frame to detach from the die. Because the disengagement push post is located in the middle of the connection between the two opposite connecting casting cavities of the flow channel, the force of the disengagement push post first acts on the middle of the connection between the two opposite connecting plastic parts of the connecting frame, and then radiates to the connection between the two opposite connecting plastic parts of the connecting frame. At this time, due to the setting of the clamping column, the connecting frame will be temporarily stuck in the flow channel, so that the push rod pushes the plastic part to disconnect from the connecting frame, and the disengagement push post continues to extend to push the connecting frame to detach from the die, so that the staff does not need to disassemble the connecting frame, further reducing the workload of the staff.

[0021] Furthermore, an end of the ejector pin away from the die is provided with an external thread, and the ejector pin is threadedly connected to the movable die seat.

[0022] By adopting the above technical solution, the ejector pin threadedly connected to the movable mold seat can facilitate the staff to adjust the position of the ejector pin in the flow channel.

[0023] Furthermore, a receiving groove for receiving the top ring is provided around the casting cavity of the female mold.

[0024] By adopting the above technical solution, the receiving groove is used to receive the top ring, thereby preventing the top ring from affecting the clamping of the punch and die.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] By setting the breaking component, it is achieved that when the injection molding is completed and the mold is demolded, the plastic fluid remaining on the flow channel of the die will form a connecting frame connecting the various plastic parts, and the connection between the connecting frame and the plastic parts is wrapped with the clamping column. At the same time, during the demolding process, the push rod gradually moves up in the casting cavity to push the plastic parts out of the casting cavity. At this time, since the connecting frame is stuck by the clamping column and the clamping column is located at the connection between the connecting frame and the plastic parts, the connection between the connecting frame and the plastic parts will be subjected to tension and break, so that the connecting frame will remain on the die and separate from the plastic parts, so that the staff does not need to process the completed plastic parts again, which reduces the processing steps and the workload of the staff, making it easier for the staff to process plastic parts.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] Example, see Figure 1 A continuous molding mold for injection molded parts includes a movable mold base 1, a die 10 arranged on the movable mold base 1, a fixed mold base 11 is arranged on the side of the die 10 away from the movable mold base 1, and a punch 12 matched with the die 10 is arranged on the fixed mold base 11. The die 10 is provided with a plurality of casting cavities 14, which are the key to the molding of plastic parts. In addition, the die 10 is also provided with a flow channel 13, which connects all the casting cavities 14, ensuring that the plastic fluid can be evenly distributed in each casting cavity 14. The punch 12 is provided with a plurality of output ends matching the casting cavities 14, which are used to form the final mold cavity of the plastic part with the casting cavity 14.

[0034] Combination Figure 2 as well as Figure 3, the female mold 10 is provided with a breaking assembly 2, and the setting of the breaking assembly 2 greatly improves the automation degree and production efficiency of the mold. The breaking assembly 2 is mainly composed of three parts: first, the clamping column 20, the clamping column 20 is T-shaped, and these T-shaped clamping columns 20 are arranged on the flow channel 13 of the female mold 10. They are located at the connection point where the flow channel 13 connects multiple casting cavities 14, and will not extend out of the flow channel 13 to affect the injection molding process. Secondly, there are multiple push rods 21, and multiple push rods 21 correspond to multiple casting cavities 14. These push rods 21 are arranged on the movable mold seat 1, and they extend into the casting cavity 14 away from one end of the movable mold seat 1, and the push rods 21 almost occupy most of the space of the casting cavity 14 when the female mold 10 is not closed. Finally, there is a driving cylinder 22, which is installed on the movable mold seat 1, and its output end is fixedly connected to the bottom surface of the female mold 10, providing a strong power for the closing and opening of the mold.

[0035] The casting cavity 14 of the female mold 10 is set to pass through the bottom surface of the female mold 10. During the mold closing process, by starting the driving cylinder 22, the female mold 10 will gradually approach the male mold 12. At this time, the push rod 21 will gradually move down in the casting cavity 14 to make enough space for the injection of the plastic fluid. When the injection molding device injects the plastic fluid into the flow channel 13 of the female mold 10 through the male mold 12, the plastic fluid will flow smoothly along the flow channel into each casting cavity and wrap the clamping column 20.

[0036] After the injection molding is completed, when demolding is performed, the plastic fluid remaining on the flow channel 13 of the die 10 will form a connecting frame connecting each plastic part. The connection point where this connecting frame connects each plastic part is wrapped with the clamping column 20, so that during the demolding process, when the push rod 21 gradually moves up in the casting cavity 14 and pushes the plastic part out of the casting cavity 14, the connecting frame will be subjected to tension due to being stuck by the clamping column 20, and thus break at this connection. In this way, the connecting frame will be retained on the die 10 and successfully separated from the plastic part. This setting not only saves the staff from the tedious steps of further processing the finished plastic parts, but also greatly reduces the processing procedures and workload, making it easier and more efficient for the staff to process plastic parts. The connecting frame retained on the die 10 only needs to be removed from the die 10, which is very convenient and quick.

[0037] Although the provision of the breaking component 2 greatly reduces the burden on the workers when processing the plastic parts, in actual operation, when the push rod 21 gradually moves upward in the casting cavity 14 and pushes the plastic part out of the casting cavity 14, since the connecting frame and the plastic part are integrally formed through the injection molding process, the breaking of the connecting frame may affect the part of the plastic part close to the connecting frame, thereby causing damage to the plastic part. In order to solve this technical problem, this embodiment is further optimized.

[0038] Specifically, in this embodiment, a fixing block 3 with a triangular cross section is arranged on the side of the clamping column 20 close to the casting cavity 14. The fixing block 3 is fixedly arranged on the die 10 and located in the flow channel 13, and the inclined surface of the fixing block 3 faces the casting cavity 14. When the plastic fluid flows smoothly along the flow channel 13 into each casting cavity, the fluid will not only wrap the clamping column 20, but also wrap the fixing block 3.

[0039] After the injection molding is completed, when demolding is performed, the plastic fluid remaining on the flow channel 13 of the female mold 10 will form a connecting frame connecting the various plastic parts. Due to the presence of the fixing block 3, a triangular notch will be formed at the connection of the connecting frame to the plastic parts. This triangular notch makes it easier for the connection between the connecting frame and the plastic parts to break. In the process of the push rod 21 gradually moving up in the casting cavity 14 and pushing the plastic parts out of the casting cavity 14, when the connecting frame is subjected to tension, this triangular notch will make it easier for the connecting frame to break at this point.

[0040] More importantly, the setting of this triangular notch also effectively prevents the connection frame from breaking and pulling the part of the plastic part close to the connection frame together. This not only reduces the scrap rate during the processing, but also ensures the integrity and quality of the plastic part. This optimized design not only improves the practicality and reliability of the mold, but also provides a more efficient and convenient processing experience for the staff.

[0041] Although the setting of the fixing block 3 effectively prevents the plastic parts from being damaged when the connecting frame breaks, and significantly reduces the processing scrap rate, a new problem also emerges: after the connecting frame breaks more easily, the plastic parts tend to be more easily retained on the output end of the punch 12 after being separated from the connecting frame. This situation forces the staff to manually remove the plastic parts from the output end of the punch 12 one by one, which greatly affects the production efficiency and adds to the inconvenience of operation.

[0042] In order to solve this technical problem, the present embodiment sets a protection component 4 on the punch 12. The protection component 4 consists of two parts: one is a top ring 40 sleeved on the output end of the punch 12, which is used to push the plastic part away from the punch 12 during demolding; the other is a top spring 41 set on the punch 12, which is used to drive the top ring 40 to move toward the die 10. One end of the top spring 41 is fixedly connected to the top ring 40, and the other end is fixedly connected to the punch 12, which is used to provide thrust to the top ring 40.

[0043] When the plastic part is injected and separated from the connecting frame, if it is sleeved on the output end of the punch 12, the top spring 41 will play its role, and it uses its own elastic force to push the top ring 40, so that the top ring 40 pushes the plastic part off the punch 12. This design not only effectively prevents the plastic part from getting stuck on the punch 12, reduces the manual operation of the staff, but also further improves the production efficiency, making the entire injection molding process smoother and more efficient.

[0044] In this embodiment, a receiving groove 15 for receiving the top ring 40 is provided around the casting cavity 14 of the die 10 . The receiving groove 15 is used to receive the top ring 40 to prevent the top ring 40 from affecting the closing of the punch 12 and the die 10 .

[0045] Reference Figure 4 In this embodiment, a rubber sleeve 23 is provided at one end of the push rod 21 extending into the casting cavity 14. The rubber sleeve 23 is elastic and transitionally matched with the casting cavity 14. The rubber sleeve 23 transitionally matched with the casting cavity 14 can prevent leakage of plastic fluid, and the rubber sleeve 23 is threadedly connected to the push rod 21. The rubber sleeve 23 threadedly connected to the push rod 21 is easy for staff to replace.

[0046] In this embodiment, the push rod 21 is threadedly connected to the movable mold base 1. The push rod 21 threadedly connected to the movable mold base 1 can make the push rod 21 easy to replace.

[0047] Although the provision of the breaking component 2 greatly reduces the labor intensity of the workers when processing plastic parts and makes the entire injection molding process smoother, it also brings about a new technical problem: since the clamping column 20 clamps the connecting frame in the flow channel 13, when the connecting frame needs to be removed from the die 10, the workers often need to exert considerable force, which undoubtedly increases the difficulty of the operation and physical exertion.

[0048] In order to solve this technical problem, the present embodiment provides a disengagement pin 5 on the movable mold base 1, one end of which is threadedly connected to the movable mold base. The disengagement pin 5 threadedly connected to the movable mold base 1 can facilitate the staff to adjust the position of the disengagement pin 5 in the flow channel 13. The other end of the disengagement pin 5 passes through the concave mold 10 and extends into the flow channel 13, and is located in the middle of the connection between the two opposite connection casting cavities 14 of the flow channel 13. During the mold closing process, the disengagement pin 5 is kept flush with the bottom surface of the flow channel 13, ensuring that the plastic fluid can flow freely in the flow channel 13 without hindrance, and the injection molding process is successfully completed.

[0049] When demolding, when the die 10 slowly descends, the detachment pillar 5 gradually extends out of the runner 13, and its top presses against the connecting frame. Since the detachment pillar 5 is located in the middle of the connection between the two opposite connecting casting cavities 14 of the runner 13, its force first acts on the middle of the connection between the two opposite connecting plastic parts of the connecting frame, and then this force gradually radiates to the connection. At this time, the clamping column 20 temporarily clamps the connecting frame in the runner 13, and at the same time, the push rod 21 pushes the plastic part to gradually disconnect from the connecting frame. Then, the detachment pillar 5 continues to extend, and its top continues to press against the connecting frame until it is completely pushed away from the die 10. This setting not only saves the staff from the trouble of disassembling the connecting frame, greatly reducing the workload, but also further improves the automation and efficiency of the entire injection molding process.

[0050] Specific implementation process: When closing the mold, the driving cylinder 22 is started to make the female mold 10 approach the male mold 12, and the push rod 21 gradually moves down in the casting cavity 14 so that the space in the casting cavity 14 is sufficient to form a plastic part, and at the same time, the top column 5 is separated and flush with the bottom surface of the flow channel 13, and then the plastic fluid is injected into the flow channel 13 of the female mold 10 through the injection molding device. When the plastic fluid flows along the flow channel 13 to each mold cavity, the flowing plastic fluid will wrap the clamping column 20 and flow into the mold cavity through the fixing block 3. After the injection molding is completed, demoulding is performed, and the driving cylinder 2 is started. 2 makes the female mold 10 approach the movable mold base 1. During the demoulding process, the push rod 21 gradually moves up in the casting cavity 14 to push the plastic part out of the casting cavity 14. At this time, since the connecting frame is clamped by the clamping column 20, and the clamping column 20 is located at the connection between the connecting frame and the plastic part, the connection between the connecting frame and the plastic part will be subjected to tension and thus broken. At this time, the ejector column 5 continues to extend to push the connecting frame to separate from the female mold 10. During the demoulding process, when the plastic part is sleeved on the output end of the punch 12, the ejector spring 41 pushes the ejector ring 40, so that the ejector ring 40 pushes the plastic part out of the punch 12.

[0051] By setting the fixed block 3, it is achieved that when the plastic fluid flows along the flow channel 13 into each mold cavity, the flowing plastic fluid will wrap the fixed block 3, and the plastic fluid remaining on the flow channel 13 of the die 10 when demolding is performed after injection molding is completed will form a connecting frame connecting each plastic part. Due to the setting of the fixed block 3, a triangular notch will be formed at the connection between the connecting frame and the plastic part. This notch makes it easier for the connecting frame to break when the push rod 21 gradually moves up in the casting cavity 14 to push the plastic part out of the casting cavity 14, and this notch can prevent the connecting frame from pulling the part of the plastic part close to the connecting frame to break together, thereby reducing the scrap rate during the processing.

[0052] By setting the protection component 4, when the plastic part is sleeved on the output end of the punch 12, the top spring 41 will press the top ring 40, so that the top ring 40 pushes the plastic part out of the punch 12, preventing the plastic part from being stuck on the punch 12 and increasing the workload of the staff.

[0053] By setting the disengagement ejector post 5, it is achieved that the disengagement ejector post 5 is flush with the bottom surface of the flow channel 13 when the mold is closed, so that the plastic fluid can flow normally in the flow channel 13. When demolding, due to the descending of the die 10, the disengagement ejector post 5 gradually extends out of the flow channel 13 and pushes against the connecting frame to disengage from the die 10. Moreover, because the disengagement ejector post 5 is located in the middle of the connection between the two opposite connecting casting cavities 14 of the flow channel 13, the force of the disengagement ejector post 5 first acts in the middle of the connection between the two opposite connecting plastic parts of the connecting frame, and then radiates to the connection between the two opposite connecting plastic parts of the connecting frame. At this time, due to the setting of the clamping post 20, the connecting frame will be temporarily stuck in the flow channel 13, so that the push rod 21 pushes the plastic part to disconnect from the connecting frame, and the disengagement ejector post 5 continues to extend to push against the connecting frame to disengage from the die 10, so that the staff does not need to disassemble the connecting frame, thereby further reducing the workload of the staff.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
