Description

TECHNICAL FIELD

[0001] The utility model relates to injection mold technical field especially relates to a soft agent cover pours liquid cover injection mold's outer ring thread demolding mechanism. BACKGROUND

[0002] With the wide application of plastic products in daily life, injection molding technology has become one of the main processes for manufacturing plastic products due to its high efficiency, flexibility and low cost. As a common plastic product, the soft agent pouring cover usually includes an inner thread and an outer thread (see Figures 10 to 11 ), which are used for sealing connection with the protective cover and the soft agent bottle respectively. However, due to the complex thread structure of the soft agent pouring cover, the following problems often occur during the traditional injection mold demolding process:

[0003] Firstly, the traditional injection mold usually adopts a direct pulling method to take out the molded cover from the mold during demolding. Since the inner and outer thread structures of the cover body are tightly matched with the mold insert, forcibly pulling can easily cause the cover body to deform, affecting the appearance and performance of the product. Secondly, the thread part is the key functional area of the soft agent pouring cover, and its precision and integrity directly affect the sealing and assembly performance of the product. However, the traditional demolding method is prone to thread surface damage due to friction or jamming, and even breakage, thereby reducing product quality. In addition, the demolding process of the traditional injection mold usually requires manual intervention, such as manual adjustment of mold parts or handling of jamming problems, which not only increases the workload of the operators, but also prolongs the production cycle and reduces the overall production efficiency. In addition, frequent friction and jamming can accelerate the wear of the mold parts, shorten the service life of the mold, and increase the cost of maintenance and replacement of the mold.

[0004] In order to solve the above problems, some improvements have been proposed in the prior art. For example, some threaded molds adopt a rotary demolding mechanism, which rotates the threaded insert to gradually separate the threads from the cover body. These improvements have reduced the risk of thread damage to some extent, but the complexity of the threaded mold rotary mechanism is relatively high in the prior art. The existing rotary demolding mechanism usually requires complex mechanical transmission components (such as gear sets, chains, hydraulic or pneumatic drive devices) to realize the rotary motion of the threaded insert. The design and manufacture of these components require high precision and accurate cooperation. The synchronization between the driving mechanism and the driven mechanism is difficult to guarantee, and the phenomenon of jamming or deviation is prone to occur. SUMMARY

Specific embodiments

[0033] In order to make the technical problems and beneficial effects of the technical solutions of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0034] The conditioner pouring cover is a common plastic product, please refer to Figures 10 to 11 The structure usually includes inner thread and outer thread, the outer thread is used for sealing connection with the conditioner bottle, and the inner thread is used for connection with the additional protective cover. For the injection molding of the above conditioner pouring cover, the traditional injection mold is prone to product deformation, thread damage and other problems during demolding due to the complexity of the cover thread structure, which affects the quality and production efficiency of the product. In order to solve the above problems, the embodiment proposes a demolding mechanism for the injection mold of the conditioner pouring cover, which realizes efficient and non-destructive demolding of the inner thread and outer thread of the cover.

[0035] Please refer to Figures 1 to 9The injection mold stripping mechanism for the conditioner pouring cap comprises a fixed mold assembly and a movable mold assembly. The fixed mold assembly comprises a fixed mold base plate 1, a hot runner plate 2, a first insert fixing plate 3, and a fixed mold plate 4 connected in sequence from top to bottom. The first insert fixing plate 3 is connected with a plurality of fixed mold inserts 5 passing through the fixed mold plate 4. The movable mold assembly comprises a movable mold base plate 6, a second insert fixing plate 7, a ejector plate 8, a support plate 9, a push plate 10, and a movable mold plate 11 connected in sequence from bottom to top. The second insert fixing plate 7 is connected with a plurality of movable mold inserts 12 passing through the ejector plate 8, the push plate 10, and the movable mold plate 11. When the mold is closed, the movable mold plate 11, the fixed mold plate 4, the fixed mold inserts 5, and the movable mold inserts 12 form a mold cavity 13 for forming the cap body. The fixed mold assembly is provided with a first stripping assembly 14 that can be movably connected with the fixed mold inserts 5 and cooperates to strip the inner thread of the cap body. The movable mold assembly and the fixed mold assembly are provided with a second stripping assembly 15 that can be movably connected with the movable mold inserts 12 and cooperates to strip the outer thread of the cap body.

[0036] In this embodiment, the fixed mold assembly comprises a fixed mold base plate 1, a hot runner plate 2, a first insert fixing plate 3, and a fixed mold plate 4 connected in sequence from top to bottom. The first insert fixing plate 3 is connected with a plurality of fixed mold inserts 5 passing through the fixed mold plate 4, which are used to form the inner thread part of the cap body. The movable mold assembly comprises a movable mold base plate 6, a second insert fixing plate 7, an ejector plate 8, a support plate 9, a push plate 10, and a movable mold plate 11 connected in sequence from bottom to top. The second insert fixing plate 7 is connected with a plurality of movable mold inserts 12 passing through the ejector plate 8, the push plate 10, and the movable mold plate 11, which are used to form the outer thread part and other non-thread parts of the cap body. When the mold is closed, the movable mold plate 11, the fixed mold plate 4, the fixed mold inserts 5, and the movable mold inserts 12 tightly cooperate to form a mold cavity 13 for forming the cap body.

[0037] The fixed mold assembly is provided with a first stripping assembly 14 that can be movably connected with the fixed mold inserts 5. During stripping, the first stripping assembly 14 can move relative to the fixed mold inserts 5, thereby cooperating to smoothly strip the inner thread part of the cap body. This design avoids damage to the thread caused by directly pulling the cap body. Correspondingly, the movable mold assembly and the fixed mold assembly are provided with a second stripping assembly 15 that can also be movably connected with the movable mold inserts 12. During stripping, the second stripping assembly 15 can move relative to the movable mold inserts 12, thereby cooperating to smoothly strip the outer thread part of the cap body. Similarly, this design also avoids the problem of thread damage. Through the cooperative action of the first stripping assembly and the second stripping assembly, efficient stripping of the inner and outer threads of the conditioner pouring cap is achieved, greatly improving production efficiency.

[0038] Further, as a preferred embodiment of the present application, the fixed half 5 comprises a first forming insert 51 fixedly connected to the first insert fixing plate 3 at one end, and the other end of the first forming insert 51 can pass through the fixed half 4, and a second forming insert 52 is rotatably connected to the outer periphery of the first forming insert 51, and the lower part of the second forming insert 52 is annularly provided with a first thread groove 521 for thread forming of the inner ring of the cover.

[0039] In the present embodiment, the first forming insert 51 is the main part of the fixed half 5, and is fixedly connected to the first insert fixing plate 3 at one end by means of fasteners or other connection means to ensure stable position during injection molding. The other end of the first forming insert 51 is designed to pass through the fixed half 4 to cooperate with the movable half insert 12 to form the mold cavity 13 when the mold is closed. The second forming insert 52 is connected to the first forming insert 51 in a movable manner, more specifically, the upper part of the first forming insert 51 is designed as a screw rod structure, and the second forming insert 52 has a matching screw sleeve structure. This design allows the second forming insert 52 to perform screw lifting motion relative to the first forming insert 51.

[0040] At the lower part of the second forming insert 52, annularly provided are first thread grooves 521 for thread forming of the inner ring of the cover. The size and shape of these thread grooves 521 need to match the thread design of the inner ring of the softener pouring cover to ensure the thread accuracy and integrity after injection molding. During injection molding, molten plastic is injected into the mold cavity 13 formed by the movable half assembly and the fixed half assembly. At this time, the second forming insert 52 is closely matched with the first forming insert 51 to jointly form the thread forming part of the inner ring of the cover. When the injection is completed, the mold starts to open. At this time, the first demolding assembly 14 starts to act, which can be a driving mechanism such as a pneumatic cylinder, a hydraulic cylinder, etc. connected to the second forming insert 52. The driving mechanism pushes the second forming insert 52 to perform screw lifting motion relative to the first forming insert 51, thereby gradually loosening the connection with the inner thread part of the formed cover. With the screw lifting of the second forming insert 52, the inner thread part of the cover is smoothly demolded, and at the same time, the second demolding assembly 15 in the movable half assembly starts to act to push the movable half insert 12 to move relative to the outer thread part of the cover, realizing the demolding of the outer thread. Finally, when the mold is completely opened, the formed softener pouring cover can be taken out of the mold. The screw connection structure between the second forming insert 52 and the first forming insert 51 enables the demolding mechanism in the present embodiment to more smoothly and uniformly separate the inner and outer thread parts of the cover, reducing the damage and deformation that may occur during demolding and improving the product quality.

[0041] Further, as a preferred embodiment of the present scheme but not limited, the first demolding assembly 14 comprises a movable plate 141 movably arranged in the first insert fixing plate 3, a plurality of bearing groups 142 corresponding to each of the fixed mold inserts 5 are fixedly arranged in the movable plate 141, the second forming inserts 52 are fixedly sleeved on the bearing groups 142, and the second forming inserts 52 penetrate through the movable plate 141. When the mold is opened, the second forming inserts 52 are pulled down by the inner ring of the cover body and rotated relative to the first forming inserts 51 until the second forming inserts 52 are separated from the cover body by rotational inertia.

[0042] In the present embodiment, the first insert fixing plate 3 has an active space for the lifting displacement of the movable plate 141, which provides a space and a basis for subsequent demolding actions, so that the demolding mechanism can flexibly realize corresponding functions. A plurality of bearing groups 142 are fixedly arranged in the movable plate 141, and these bearing groups 142 are one-to-one corresponding to each of the fixed mold inserts 5. The bearing groups 142 can be composed of one or more bearings, and the main function is to reduce friction and ensure that the second forming inserts 52 can rotate smoothly. This one-to-one corresponding design ensures that each second forming insert 52 corresponding to each fixed mold insert 5 can be stably supported and well rotated, which is beneficial to improve the stability and reliability of the entire demolding process. Each bearing group 142 is fixedly sleeved on the corresponding second forming insert 52, and the second forming insert 52 penetrates through the movable plate 141. This sleeving and penetrating connection mode forms an organic whole among the second forming insert 52, the bearing group 142 and the movable plate 141, more specifically, the bearing group 142 provides rotation support for the second forming insert 52, and the movable plate 141 limits the movement direction of the second forming insert 52 to a certain extent, ensuring that it performs the pulling-down and rotating actions on a specific track.

[0043] When the mold starts to open, the fixed mold assembly and the movable mold assembly gradually separate. Since the inner thread of the cover is formed by the first thread groove 521 on the second forming insert 52 during the injection molding process, the cover is tightly fitted with the second forming insert 52. At this time, the movement of the cover will drive the second forming insert 52 that is fitted therewith to have a downward pulling tendency. In the process of the cover pulling down the second forming insert 52, since the second forming insert 52 is rotationally connected with the first forming insert 51, and the helical shape of the inner thread determines that rotation will inevitably occur when pulling down. The presence of the bearing set 142 greatly reduces the friction when the second forming insert 52 rotates, so that the second forming insert 52 can smoothly rotate relative to the first forming insert 51. With the continuous opening of the mold, the second forming insert 52 is constantly pulled down and rotated. When a certain degree is reached, the second forming insert 52 will be separated from the cover by using the rotational inertia, thereby completing the demolding process of the inner thread of the cover. The rotational inertia plays a key role here, which helps the second forming insert 52 to completely come out of the inner thread of the cover, avoids the jamming phenomenon between the threads, and ensures the smooth demolding. Through the cooperative work of the movable plate 141, the bearing set 142 and the second forming insert 52, the first demolding assembly ingeniously utilizes the movement of the cover when the mold is opened, and realizes the automatic demolding of the inner thread of the cover. This design not only improves the demolding efficiency and reduces manual intervention, but also effectively avoids the demolding damage caused by improper manual operation, and ensures the product quality and production stability.

[0044] Further, as a preferred embodiment of the present scheme but not limited, the bearing set 142 includes a first bearing 1421 and a second bearing 1422 sleeved on the outer periphery of the second forming insert 52, the outer periphery of the second forming insert 52 is annularly provided with a limiting protrusion 522, and the limiting protrusion 522 is clamped between the plain bearing and the deep groove bearing.

[0045] Preferably, the first bearing 1421 is a plain bearing sleeved on the outer periphery of the second forming insert 52, and mainly bears axial load to adapt to the axial tension that the second forming insert 52 may generate during the demolding process, and ensure the stable movement of the second forming insert 52 in the axial direction. In the process of the cover pulling down the second forming insert 52, the plain bearing can effectively support and guide this axial movement, and reduce the axial friction and shaking.

[0046] Preferably, the second bearing 1422 is a deep groove bearing, also sleeved on the outer periphery of the second forming insert 52. Deep groove bearings are mainly used to bear radial loads, but can also bear certain axial loads. When the second forming insert 52 rotates relative to the first forming insert 51, the deep groove bearing can ensure its stability in the radial direction, making the rotation smoother, reducing the deviation and jamming caused by radial force, and ensuring that the second forming insert 52 can rotate accurately according to the predetermined trajectory.

[0047] In this embodiment, the limiting protrusion 522 plays the role of accurately defining the relative position of the plane bearing and the deep groove bearing. It can prevent the plane bearing and the deep groove bearing from moving axially during the movement of the second forming insert 52, ensuring that the two bearings always maintain the correct relative positional relationship, thereby ensuring the stability and reliability of the entire bearing set. At the same time, the limiting protrusion 522 can also share the axial and radial loads to some extent, further enhancing the stability of the movement of the second forming insert 52. Through this bearing set structure composed of a plane bearing, a deep groove bearing and a limiting protrusion 522, the second forming insert 52 can be provided with all-round support and stable movement conditions. During the thread demolding process of the inner side of the cover, it can effectively bear the axial downward force to ensure that the second forming insert 52 is smoothly pulled down, and can also ensure the radial stability during rotation, so that the second forming insert 52 can rotate flexibly and smoothly relative to the first forming insert 51.

[0048] Further, as a preferred embodiment of the present scheme but not limited, the movable plate 141 comprises an upper floating plate 1411, the bottom of the upper floating plate 1411 is fixedly connected with a lower floating plate 1412, the upper floating plate 1411 is internally fixed with the plane bearing 1421, and the lower floating plate 1412 is internally fixed with the deep groove bearing 1422.

[0049] In this embodiment, the movable plate adopts a layered design, which is composed of an upper floating plate 1411 and a lower floating plate 1412. The upper floating plate 1411 is located at the upper part, and the lower floating plate 1412 is fixedly connected at the bottom thereof. This layered design makes it more convenient to install and maintain the bearings. If a certain bearing has a problem, such as wear or damage, only the corresponding upper floating plate or lower floating plate needs to be operated, without the need to disassemble the entire movable plate on a large scale, thereby reducing the difficulty and cost of maintenance.

[0050] Further, as a preferred embodiment of the present scheme but not limited, the first demolding assembly 14 comprises a boosting device 143 arranged on the upper part of the movable plate 141. When the mold is opened, the boosting device 143 makes the movable plate 141 have a tendency to move away from the fixed mold base plate 1.

[0051] In this embodiment, the booster device 143 is a key component installed on the upper part of the movable plate 141, which mainly provides a pushing force for the movable plate 141 to move away from the fixed platen 1 when the mold is opened, thus helping to speed up the separation process of the movable plate 141 and the second molding insert 52 on it from the cover, thereby improving the demolding efficiency and reliability.

[0052] Specifically, the booster device 143 can be one or more cylinders, hydraulic cylinders, springs, or other mechanical devices that can provide a pushing force. These devices are precisely installed on the upper part of the movable plate 141, and the booster device 143 quickly generates a pushing force to push the movable plate 141 and the second molding insert 52 on it to move downward and away from the fixed platen 1.

[0053] Further, as a preferred embodiment of the present solution but not limited, the booster device 143 includes a plurality of first elastic members 1431 evenly arranged on both sides of the upper part of the movable plate 141, and the upper part of the movable plate 141 and the lower part of the fixed platen 1 are respectively provided with first mounting slots 1432 and second mounting slots 1433, the first elastic members 1431 pass through the hot runner plate 2 and the first insert fixing plate 3, and the two ends of the first elastic members 1431 are respectively arranged in the first mounting slots 1432 and the second mounting slots 1433.

[0054] In this embodiment, the first elastic member 1431 is the core component of the booster device 143, which provides a pushing force for the movable plate 141 to move away from the fixed platen 1. The first elastic member 1431 is preferably a spring, which can provide a stable pushing force and is easy to install and maintain. The first mounting slot 1432 is a slot arranged on the upper part of the movable plate 141 for mounting one end of the first elastic member 1431. The shape and size of these slots match those of the first elastic member 1431 to ensure that the first elastic member 1431 can be firmly installed on the movable plate 141. Similarly, the second mounting slot 1433 is a slot arranged on the lower part of the fixed platen 1 for mounting the other end of the first elastic member 1431. Like the first mounting slot 1432, these slots also match the shape and size of the first elastic member 1431. When the mold is in a closed state, the first elastic member 1431 is compressed and stores energy. When the mold is opened, the first elastic member 1431 releases the stored energy to push the movable plate 141 to move downward, thus speeding up the demolding process.

[0055] In order to ensure that the first elastic member 1431 can smoothly pass through each component of the mold, the hot runner plate 2 and the first insert fixing plate 3 are also designed with corresponding through holes or channels. The size and position of these through holes or channels need to match those of the first elastic member 1431 to ensure that the first elastic member 1431 can smoothly pass through and be fixed in the first mounting slot 1432 and the second mounting slot 1433.

[0056] Further, as a preferred embodiment of the present application, the lower part of the movable plate 141 is further provided with a reset device 144, which pushes the movable plate 141 away from the movable die assembly when the mold is closed. The upper end of the reset movable plate 141 abuts against the first insert fixing plate 3 when it is reset.

[0057] In this embodiment, the reset device 144 is installed on the lower part of the movable plate 141. Its main function is to provide a pushing force for the movable plate 141 away from the movable die assembly when the mold is closed, ensuring that the movable plate 141 can be accurately reset to the initial position. The reset device 144 can be one or more cylinders, hydraulic cylinders, springs, or other mechanical devices that can provide a pushing force. These devices are precisely installed on the lower part of the movable plate 141, ensuring that the movable plate 141 is accurately reset to the initial position when the mold is closed. This provides stable conditions for the next injection molding process, ensuring product quality and production efficiency.

[0058] Preferably, the reset device 144 includes a plurality of return rods evenly arranged on the lower part of the movable plate 141, and the fixed die plate 4 is provided with a plurality of through holes corresponding to the return rods. When the mold is closed, the lower end of the return rod abuts against the upper end of the movable die plate.

[0059] In this embodiment, the reset device 144 is composed of a plurality of return rods evenly arranged on the lower part of the movable plate 141. These return rods serve as the core components of the reset device 144, responsible for pushing the movable plate 141 to reset when the mold is closed. In order to ensure that the return rods can smoothly pass through each component of the mold, the fixed die plate 4 needs to be designed with through holes that match the number, position, and size of the return rods. These through holes allow the return rods to move freely during the mold opening and closing process without being hindered.

[0060] In actual production, after the mold is opened and the demolding process is completed, the movable plate 141 and the second molding insert 52 on it are in the lower part of the mold of the fixed die assembly. At this time, each component of the mold begins to prepare for closing. As the mold gradually closes, the movable die plate 11 begins to move upwards. When the upper end of the movable die plate 11 gradually approaches the lower end of the return rod, the return rod begins to receive an upward pushing force from the movable die plate 11.

[0061] This pushing force is transmitted to the movable plate 141 through the return rod, pushing the movable plate 141 and the second molding insert 52 on it to move upwards. At the same time, the upper end of the movable plate 141 gradually approaches the first insert fixing plate 3. When the movable die plate is completely closed in place, the lower end of the return rod abuts against the upper end of the movable die plate. At this time, the movable plate 141 is also accurately reset to the initial position, with its upper end abutting against the first insert fixing plate 3. After the mold is completely closed, the injection molding machine begins to inject molten plastic material. The plastic material fills the mold cavity and forms the final product of the flexible agent pouring cover after cooling.

[0062] Further, as a preferred embodiment of the present application but not limited, the movable die insert 12 comprises a third forming insert 121 fixed at one end of the second insert fixing plate 7, the other end of the third forming insert 121 can extend into the mold cavity 13 through the ejector plate 8, the support plate 9, the push plate 10 and the movable die plate 11, the third forming insert 121 is sleeved with a fourth forming insert 122 at the periphery, one end of the fourth forming insert 122 is fixed to the second insert fixing plate 7 and the other end can extend into the mold cavity 13 through the ejector plate 8, the support plate 9, the push plate 10 and the movable die plate 11, and is used to cooperate with the fixed die insert 5 to form the inner thread of the cap, the fourth forming insert 122 is rotatably connected with a fifth forming insert 123 at the periphery, the lower part of the fifth forming insert 123 is connected with the second demolding assembly 15, and the upper end can extend into the mold cavity 13 through the ejector plate 8, the support plate 9, the push plate 10 and the movable die plate 11, and a second thread groove 1231 for forming the outer thread of the cap is arranged at the upper part of the fifth forming insert 123.

[0063] In the embodiment, the second demolding assembly 15 connected to the lower part of the fifth forming insert 123 plays a role when the mold is opened. Since the fifth forming insert 123 is rotatably connected with the fourth forming insert 122, the second demolding assembly 15 can drive the fifth forming insert 123 to rotate relative to the fourth forming insert 122, so that the formed outer thread of the cap is separated from the fifth forming insert 123, and the demolding of the outer thread of the cap is realized. In combination with the first demolding assembly 14 mentioned above, the demolding of the inner thread of the cap is realized, and the demolding mechanism of the injection mold can completely complete the demolding process of the lotion cap with inner and outer threads.

[0064] Further, as a preferred embodiment of the present application but not limited, the second demolding assembly 15 comprises a driving mechanism 151 located between the fixed die assembly and the movable die assembly, the fifth forming insert 123 is provided with a driven mechanism 152 connected with the driving mechanism 151, and a linkage 153 is arranged between any two driven mechanisms 152.

[0065] In the embodiment, the driving mechanism 151 is located between the fixed die assembly and the movable die assembly, and is the power source of the second demolding assembly 15. The driving mechanism 151 can be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder or any mechanism capable of providing linear or rotary motion. The output end of the driving mechanism 151 is designed with a connecting interface for connecting with the driven mechanism 152 to transmit power. The driven mechanism 152 is arranged on the fifth forming insert 123 and cooperates with the output end of the driving mechanism 151. Correspondingly, the driven mechanism 152 can be a connecting rod, a connecting sleeve, a gear or any mechanism capable of matching the output end of the driving mechanism 151. The linkage 153 is arranged between any two driven mechanisms 152 to ensure that multiple fifth forming inserts 123 can rotate synchronously. Similarly, the linkage 153 can be a connecting rod, a chain, a gear, a synchronous belt or any mechanism capable of achieving synchronous motion. One end of the linkage 153 is connected with one driven mechanism 152, and the other end is connected with another driven mechanism 152, thereby forming a closed-loop synchronous motion system. Through the cooperation of the driving mechanism 151, the driven mechanism 152 and the linkage 153, the second demolding assembly 15 in the embodiment can accurately control the rotary motion of the fifth forming insert 123, thereby achieving smooth demolding of the outer ring threaded part of the injection molded part. The design of the linkage 153 ensures the synchronous rotation of multiple fifth forming inserts 123, thereby improving the efficiency and consistency of demolding.

[0066] Further, as a preferred embodiment of the present scheme but not limited, the driving mechanism 151 comprises a screw rod 1511 fixedly connected with the fixed die assembly at one end and penetrating through the movable die assembly at the other end, a screw sleeve 1512 matched with the screw rod 1511 is sleeved on the outer periphery of the screw rod 1511, a driving gear ring 1513 capable of cooperating with the driven mechanism 152 is arranged on the outer periphery of the screw sleeve 1512, third bearings 1514 fixedly sleeved with the screw sleeve 1512 are arranged on the upper and lower sides of the driving gear ring 1513, respectively, the third bearings 1514 are embedded in the ejector rod plate 8 and the support plate 9, respectively, when the mold is opened, the screw rod 1511 moves away from the screw sleeve 1512 to rotate the driving gear ring 1513, and drives the driven mechanism 152 to separate the fifth forming insert 123 from the inner ring thread of the cover.

[0067] In the embodiment, the screw rod 1511 is the core component of the driving mechanism 151, one end of which is fixedly connected with the fixed mold assembly, and the other end penetrates through the movable mold assembly. The screw sleeve 1512 is sleeved on the outer periphery of the screw rod 1511 and is in threaded cooperation with the screw rod 1511. When the screw rod 1511 and the screw sleeve 1512 move relatively in the axial direction, the relative movement is converted into the rotary motion of the screw sleeve 1512. The driving gear ring 1513 is annularly arranged on the outer periphery of the screw sleeve, which is used to be connected with the driven mechanism to transmit the rotary motion of the screw sleeve 1512 to the driven mechanism. The driving gear ring 1513 is equivalent to a power output component, which converts the motion between the screw rod 1511 and the screw sleeve 1512 into power that can drive the driven mechanism 152. The third bearing 1514 is fixedly sleeved with the screw sleeve 1512 on the upper and lower sides of the driving gear ring 1513, and the third bearing 1514 is preferably a roller bearing. The roller bearings are embedded in the thimble plate 8 and the support plate 9, which play the role of supporting and positioning the screw sleeve, and ensure that the screw sleeve 1512 can rotate smoothly. At the same time, the rotary motion of the screw sleeve 1512 is isolated from the thimble plate 8 and the support plate 9 to avoid mutual interference, and the stability and reliability of the entire mechanism are ensured. Through the cooperation of the screw rod 1511, the screw sleeve 1512, the driving gear ring 1513 and the third bearing 1514, the driving mechanism 151 in the embodiment can accurately control the rotary motion of the fifth forming insert 123, so as to realize the smooth demolding of the outer thread part of the injection molded part. The application of the roller bearing effectively reduces the friction resistance of the driving gear ring 1513 during rotation, improves the demolding efficiency and the service life of the mold.

[0068] Further, as a preferred embodiment of the present scheme but not limited, the driven mechanism 152 comprises a driven gear ring 1521 annularly arranged on the fifth forming insert 123, and a fourth bearing 1522 is fixedly sleeved with the fifth forming insert 123 on the upper and lower sides of the driven gear ring 1521, respectively. The fourth bearing 1522 is embedded in the thimble plate 8 and the support plate 9, respectively, and the fourth bearing 1522 is preferably a deep groove bearing. When the mold is opened, the driving mechanism 151 rotates the driven gear ring 1521 and makes the fifth forming insert 123 disengage from the inner thread of the cover, and the linkage 153 is arranged between any two adjacent driven gear rings 1521, and the linkage 153 is preferably a gear matched with the tooth shape of the driven gear ring 1521.

[0069] Specifically, in actual production, when the mold is opened, the screw rod 1511 in the driving mechanism 151 begins to move linearly relative to the screw sleeve 1512, and the screw sleeve 1512 rotates accordingly. The rotation of the screw sleeve 1512 is transmitted to the driven gear ring 1521 in the driven mechanism 152 through the driving gear ring 1513. After receiving the rotation power transmitted by the driving gear ring 1513, the driven gear ring 1521 begins to rotate around the axis of the fifth forming insert 123. Since the driven gear ring 1521 is fixedly connected to the fifth forming insert 123, and the fifth forming insert 123 is sleeved on the fourth forming insert 122 and can rotate relative to the axis thereof, the rotation of the driven gear ring 1521 will drive the fifth forming insert 123 to rotate together. The rotation of the fifth forming insert 123 causes the outer thread part of the cover body to gradually separate from the second screw groove 1231 on the fifth forming insert 123. At the same time, since the linkage 153 is arranged between any two adjacent driven gear rings 1521, when one driven gear ring 1521 rotates, the other driven gear rings 1521 will also rotate synchronously through the transmission action of the linkage 153, thereby ensuring the synchronous rotation between the plurality of fifth forming inserts 123. With the continuous rotation of the fifth forming insert 123, the outer thread part of the injection molded part is completely separated from the fifth forming insert 123, and at this time, the injection molded part of all the cover bodies can be smoothly taken out.

[0070] Through the cooperation of the driven gear ring 1521 and the fourth bearing 1522, the driven mechanism 152 in the embodiment can accurately receive the rotation power transmitted by the driving mechanism 151 and drive the fifth forming insert 123 to rotate synchronously. The arrangement of the linkage 153 ensures the synchronous rotation between the plurality of fifth forming inserts 123, and improves the consistency and stability of demolding.

[0071] Further, as a preferred embodiment of the present scheme but not limited, the movable mold insert 12 comprises a sixth forming insert 124 sleeved on the outer periphery of the fifth forming insert 123, the lower end of the sixth forming insert 124 is fixedly arranged on the push plate 10, and the upper end thereof can extend into the mold cavity 13 through the movable mold plate 11, a plurality of rotation stopping gear grooves 1241 are arranged around the upper end of the sixth forming insert 124, so as to facilitate the separation of the fifth forming insert 123 and the outer thread of the cover body when the mold is opened.

[0072] In the present embodiment, the movable die insert 12 comprises a sixth forming insert 124, which is sleeved on the outer periphery of the fifth forming insert 123 and is fixedly installed at the lower end of the push plate 10, which means that the sixth forming insert 124 moves together with the push plate 10 in the mold clamped state. In order to solve the problem that the fifth forming insert 123 cannot be rotated and demolded due to too tight fit between the fifth forming insert 123 and the outer thread of the cover body in the mold opening state, a plurality of rotation stopping tooth grooves 1241 located in the mold cavity 13 in the mold clamped state are designed around the upper end of the sixth forming insert 124. These rotation stopping tooth grooves 1241 make the cover body form a protruding structure 100 adapted to the rotation stopping tooth grooves 1241, thereby providing a non-rotating support point for the fifth forming insert 123 during mold opening, preventing rotation or jamming due to tight fit of the thread, and ensuring that the fifth forming insert 123 can smoothly separate from the thread of the outer periphery of the cover body during mold opening.

[0073] Further, as a preferred embodiment of the present scheme but not limited, the second demolding assembly 15 comprises an ejection mechanism 154 provided on the movable die assembly, which ejects the cover body when the fifth forming insert 123 separates from the thread of the outer periphery of the cover body.

[0074] In the present embodiment, the ejection mechanism 154 can adopt a common needle type or push plate type structure, and tightly cooperates with other components before the text during the entire demolding process. First, the first demolding assembly 14 completes the demolding of the thread on the inner side of the cover body, and the driving mechanism 151 and the driven mechanism 152 of the second demolding assembly 15 cooperatively realize the demolding of the thread of the outer periphery of the cover body. When these demolding actions are completed, the ejection mechanism 154 is timely started to eject the cover body. This cooperative work ensures the continuity and efficiency of the demolding process, ensures that the injection molding production can proceed smoothly, and avoids the production interruption or product damage caused by the cover body remaining in the mold.

[0075] Specifically, the ejection mechanism 154 includes a plurality of guide rods 1541 fixed on the ejector plate 8, a first movable slot 1542 and a second movable slot 1543 are respectively arranged in the support plate 9 and the push plate 10 and matched with the guide rods 1541, the bottom of the second movable slot 1543 is embedded with a limiting ring 1544, the guide rod 1541 passes through the limiting ring 1544 and cooperates with the limiting ring 1544 to define the movable stroke of the push plate 10, a second elastic member 1545 is arranged in the first movable slot 1542, the second elastic member 1545 is sleeved on the guide rod 1541 and the two ends thereof are respectively abutted against the limiting ring 1544 and the upper end of the ejector plate 8, when the fifth forming insert 123 is threadedly separated from the outer circle of the cover, the second elastic member 1545 drives the push plate 10 to move away from the support plate 9, then the push plate 10 moves away from the movable die plate 11 and makes the stopper tooth groove 1241 of the sixth forming insert 124 separated from the cover, so that the cover is ejected by the upper end of the movable die plate 11.

[0076] In actual production, when the cover is injection molded, the mold starts the mold opening process. When the fifth forming insert 123 is completely separated from the outer circle of the cover, the second elastic member 1545 starts to work, and the elastic potential energy is released to directly act on the bottom of the limiting ring 1544, drive the push plate 10 and the movable die plate 11 to move away from the support plate 9 together, and drive the sixth forming insert 124 to move at the same time. In this process, the stopper tooth groove 1241 on the sixth forming insert 124 gradually separates from the cover, preparing for the ejection of the cover. Since the limiting ring 1544 is embedded in the bottom of the second movable slot 1543 and cooperates with the guide rod 1541 to define the movable stroke of the push plate 10, when the push plate 10 reaches the maximum movable stroke, that is, the limiting ring 1544 abuts against the corresponding limiting end on the upper part of the guide rod 1541, the movable die plate 11 starts to move away from the push plate 10. It should be noted that in the embodiment, the lower edge of the cover is in contact with the upper end surface of the movable die plate 11 during the molding of the cover injection molded part, so as the movable die plate 11 moves away from the push plate 10, the movable die plate 11 drives the cover to separate from the sixth forming insert 124, more specifically, separates the cover from the stopper tooth groove 1241 on the upper end of the sixth forming insert 124 and ejects the cover. In summary, the above-mentioned ejection mechanism 154 cooperates with other structures of the mold to timely and effectively eject the cover after the cover is completely demolded from the inner and outer circle threads, ensuring the efficiency and continuity of the demolding process of the entire injection mold and improving the production efficiency.

[0077] Further, as a preferred embodiment of the present scheme, a plurality of sprue hooks 16 are arranged in the movable die assembly, one end of the sprue hook 16 is embedded in the push plate 10, and the other end extends through the movable die plate 11 and into the mold cavity 13.

[0078] In the actual injection molding process, the plastic melt enters the mold cavity 13 through the corresponding flow channel in the mold to form a compliant agent pouring cover. The water gap is the channel part of the plastic melt from the flow channel into the mold cavity, and the water gap hook needle 16 extends into the mold cavity 13 and contacts the plastic of the water gap part and is connected with the water gap during the molding process. During demolding, when the mold is opened for demolding operation, the push plate will move. Since one end of the water gap hook needle 16 is embedded in the push plate, the movement of the push plate drives the water gap hook needle to move together. The water gap hook needle 16 can hook the water gap out of the mold by using the connection relationship between the water gap hook needle 16 and the water gap in the mold cavity. This helps to separate the water gap and the molded cover from the mold during demolding, avoids the water gap remaining in the mold, and ensures the smooth progress of the mold demolding process. In particular, the end of the water gap hook needle 16 is spherical, and compared with a sharp or flat end, the spherical end has a larger contact area with the water gap to disperse the hooking force and reduce the risk of the water gap being broken or damaged due to excessive local stress. Since the water gap of the compliant agent pouring cover is usually thin or thin, this dispersion force characteristic is particularly important, which can effectively prevent the water gap from being pulled off during demolding, affecting production efficiency and product quality.

[0079] Further, as a preferred embodiment of the present scheme but not limited, a plurality of guide mechanisms 17 for limiting the opening and closing stroke are arranged between the fixed mold assembly and the movable mold assembly, specifically, two are arranged symmetrically on both sides of the entire mold.

[0080] More specifically, the guide mechanism 17 includes guide blocks 171 fixed to the outer sides of the fixed mold plate 4 and the movable mold plate 11, respectively, and the guide blocks 171 are provided with openings and guide rails 172 are arranged in the openings, and the two ends of the guide rails 172 are respectively provided with limiting ends 173 to prevent them from being pulled out of the guide blocks 171.

[0081] In the embodiment, the guide blocks 171 are the main supporting components of the guide mechanism and are fixedly installed on the outer sides of the fixed mold plate 4 and the movable mold plate 11. The guide rails 172 are arranged in the openings of the guide blocks 171 and are used to guide the accurate movement of the movable mold plate 11 relative to the fixed mold plate 4, and the two ends of the guide rails 172 are respectively provided with limiting ends 173 to limit the opening and closing stroke of the mold. The limiting end can be a stop block fixed at the two ends of the guide rail, or a limiting structure processed on the guide rail itself. Through the arrangement of the guide mechanism 17, the demolding mechanism of the injection mold of the embodiment not only improves the stability and accuracy of the mold opening and closing, but also effectively prolongs the service life of the mold. At the same time, the design of the limiting end also ensures the accurate control of the opening and closing stroke of the mold, which provides a strong guarantee for the high-quality production of the compliant agent pouring cover.

[0082] The working principle of the utility model is:

[0083] The embodiment provides a demolding mechanism of an injection mold for a conditioner pouring cover. Through cooperation of a first demolding assembly and a second demolding assembly, efficient and non-damaging demolding of an inner ring thread and an outer side thread of a cover body is realized. The first demolding assembly utilizes a movable plate, a bearing set and a boosting device to drive a second forming insert in a fixed mold insert to rotate and pull down at mold opening, and the demolding of the inner ring thread is completed by means of rotational inertia; the second demolding assembly drives a fifth forming insert in a movable mold insert to rotate synchronously through a driving mechanism, a driven mechanism and a linkage, so that the outer side thread is separated. After the demolding of the inner and outer threads is completed, the ejection mechanism separates a push plate and a movable mold plate by means of an elastic element, and the cover body is smoothly ejected. In addition, the mold is provided with a guide mechanism and a gate hook needle, so that the mold opening and closing stroke is accurate and stable, and the residual gate problem is effectively solved. The overall design ingeniously combines mechanical structures and motion principles, significantly improves the demolding efficiency and product quality, and solves the problem that the traditional injection mold is prone to cause product deformation or thread damage.

[0084] The above is an embodiment provided in combination with specific content, and it is not considered that the specific implementation of the present application is limited to these descriptions. Any similar structure or method as the present application, or any technical deduction or replacement made on the basis of the concept of the present application, should be considered as the protection scope of the present application.
