[0003] For example, a Chinese patent discloses an injection mold for a car B-pillar [application number: 201921219200.0], which includes a front mold A plate, a rear mold B plate, a rear mold insert, a rear mold core, an inclined ejector block, an ejector plate, and a hot runner plate. The front mold A plate can be disposed near or away from one side of the rear mold B plate. The rear mold core is fixed to the rear mold B plate. The rear mold insert is detachably sleeved on the outer periphery of the rear mold core. When the front mold A plate is close to the rear mold B plate, the front mold A plate and the rear mold core together form an injection cavity adapted to the car B-pillar. The rear mold insert surrounds the joint edge of the front mold A plate and the rear mold core, and the rear mold insert closes the outer edge of the injection cavity. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a high-precision injection molding mold with zero breakage in the B-pillar clamping line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision injection molding mold with zero breakage in B-pillar clamping line includes an upper mold plate and a lower mold plate. Two molding cavities are symmetrically arranged between the upper and lower mold plates. An upper and lower stacked external core pulling mechanism is provided on the outer side of the molding cavity, and an internal core pulling mechanism is provided on the inner side of the molding cavity. The upper and lower stacked external core pulling mechanism and the internal core pulling mechanism are arranged opposite to each other. A top plate is connected to the lower side of the lower mold plate through a lifting mechanism. Two inclined ejection mechanisms corresponding to the two molding cavities are provided on the top plate.

[0006] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the upper and lower stacked external core pulling mechanism includes an external core pulling seat horizontally arranged outside the molding cavity. The inner end of the external core pulling seat is provided with an external core block connected to the molding cavity. The external core pulling seat is slidably arranged on the lower template through a first limiting structure. A translation driver is provided on the lower side of the external core pulling seat. The output end of the translation driver faces the outside of the lower template. The translation driver is embedded in the driver mounting groove on the lower template. The output shaft end of the translation driver is connected to the external core pulling seat through an L-shaped connecting plate.

[0007] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the first limiting structure includes a first limiting block that is detachably fixed to the lower template by a number of bolts, and the first limiting block is inserted into the first limiting groove at the bottom of the outer core-pulling seat.

[0008] In the aforementioned high-precision injection molding mold with zero breakage along the B-pillar clamping line, an outer limiting block is also fixedly connected to the side of the lower template, and the outer limiting block is located on the outside of the outer core-pulling seat.

[0009] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the inner core pulling mechanism includes an inner core pulling seat that is slidably disposed on the lower template and located inside the molding cavity via a second limiting structure. The inner end of the inner core pulling seat is provided with an inner core block that is connected to the molding cavity. The upper template is provided with a driving structure that is connected to the inner core pulling seat.

[0010] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the driving structure includes a driving rod that is tilted and fixed at the bottom of the upper template. The bottom of the driving rod is inserted into the inner core-pulling seat and slidably connected to the inner core-pulling seat.

[0011] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the second limiting structure includes a second limiting block that is detachably fixed to the lower template by several bolts, and the second limiting block is inserted into the second limiting groove at the bottom of the inner core pull seat.

[0012] In the aforementioned high-precision injection molding mold with zero breakage of B-pillar clamping line, the inclined ejection mechanism includes an outer inclined ejection component corresponding to the outer core block and an inner inclined ejection component corresponding to the inner core block. When the product is ejected under the drive of the top plate, the outer inclined ejection component can move obliquely upward away from the outer core block, and the inner inclined ejection component can move obliquely upward away from the inner core block.

[0013] In the above-mentioned B-pillar clamping line zero-discontinuity high-precision injection molding mold, the outer inclined top assembly includes a number of outer inclined top blocks arranged along the inner edge of the outer core block.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0019] like Figures 1-4 As shown, a high-precision injection molding mold with zero breakage of B-pillar clamping line includes an upper mold plate 1 and a lower mold plate 2. Two molding cavities 3 are symmetrically arranged between the upper mold plate 1 and the lower mold plate 2. An upper and lower stacked external core pulling mechanism 4 is arranged on the outside of the molding cavity 3, and an internal core pulling mechanism 5 is arranged on the inside of the molding cavity 3. The upper and lower stacked external core pulling mechanism 4 and the internal core pulling mechanism 5 are arranged opposite to each other. The lower side of the lower mold plate 2 is connected to a top plate 7 through a lifting mechanism 6. The top plate 7 is provided with two inclined ejection mechanisms corresponding to the two molding cavities 3 respectively.

[0020] In this utility model, the mold symmetrically arranges two forming cavities between the upper and lower mold plates, and sets an upper and lower stacked external core pulling mechanism on the outside of the forming cavity and an internal core pulling mechanism on the inside, so as to achieve a compact layout of the core pulling mechanism. The upper and lower stacked design replaces the traditional external structure, which greatly reduces the space occupied by the mold. At the same time, in conjunction with the inclined ejection mechanism on the top plate, the product is stably ejected, improving the overall integration and space utilization of the mold.

[0021] Specifically, the stacked external core-pulling mechanism 4 includes an external core-pulling seat 8 horizontally disposed outside the molding cavity 3. An external core block 9, connected to the molding cavity 3, protrudes from the inner end of the external core-pulling seat 8. The external core-pulling seat 8 is slidably disposed on the lower mold plate 2 via a first limiting structure. A translation driver 10 is disposed on the lower side of the external core-pulling seat 8, with its output end facing outwards from the lower mold plate 2. The translation driver 10 is embedded in a driver mounting groove on the lower mold plate 2. The output shaft end of the translation driver 10 is connected to the external core-pulling seat 8 via an L-shaped connecting plate 11. The stacked external core-pulling mechanism adopts an integrated design of the external core-pulling seat and the external core block. The translation driver is embedded in the driver mounting groove of the lower mold plate, achieving a built-in driver layout. The L-shaped connecting plate connects the translation driver and the external core-pulling seat, ensuring stable transmission of driving power. This structure avoids the problem of traditional external drivers occupying extra space. Simultaneously, the sliding assembly ensures precise and smooth external core-pulling action, improving core-pulling efficiency and mold operation stability.

[0022] Those skilled in the art should understand that the translation actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0023] Specifically, the first limiting structure includes a first limiting block 12 detachably fixed to the lower template 2 by several bolts. The first limiting block 12 is inserted into the first limiting groove at the bottom of the outer core-pulling seat 8. The first limiting structure, through the cooperation of the detachable first limiting block and the first limiting groove at the bottom of the outer core-pulling seat, forms a precise sliding guide. The bolt connection facilitates the installation and replacement of the limiting block, ensuring that the outer core-pulling seat moves along a fixed trajectory during translation, avoiding deviation or shaking. This design improves the motion accuracy of the outer core-pulling mechanism, ensures precise docking between the outer core block and the molding cavity, reduces mold wear, and extends service life.

[0024] Preferably, an outer limiting block 13 is also fixedly connected to the side of the lower template 2, and the outer limiting block 13 is disposed on the outside of the outer core-pulling seat 8. The outer limiting block on the side of the lower template is disposed on the outside of the outer core-pulling seat, forming an extreme position constraint for the outer core-pulling action. This structure can effectively limit the maximum translational distance of the outer core-pulling seat, avoid damage to the mechanism or affect subsequent mold closing actions due to excessive core pulling, ensure the consistency of the core-pulling stroke through mechanical limiting, improve the safety and reliability of mold operation, and reduce debugging and maintenance costs.

[0025] Specifically, the inner core-pulling mechanism 5 includes an inner core-pulling seat 14 slidably mounted on the lower template 2 and located inside the molding cavity 3 via a second limiting structure. An inner core block 15, connected to the molding cavity 3, protrudes from the inner end of the inner core-pulling seat 14. A driving structure connected to the inner core-pulling seat 14 is provided on the upper template 1. The inner core-pulling mechanism employs a combination design of the inner core-pulling seat and the inner core block. Sliding guidance is achieved through the second limiting structure, and power is provided by the driving structure of the upper template. This design allows the inner core-pulling mechanism to be positioned relative to the outer core-pulling mechanism, forming bidirectional precise control of the molding cavity. This avoids the problem of insufficient product molding accuracy caused by traditional single-sided core-pulling. Furthermore, the inner core-pulling mechanism is integrated inside the mold, further optimizing the spatial layout and improving the overall compactness of the mold.

[0026] Specifically, the drive structure includes a drive rod 16 that is tilted and fixed to the bottom of the upper mold plate 1. The bottom of the drive rod 16 is inserted into the inner core-pulling seat 14 and slidably connected to the inner core-pulling seat 14. The drive structure utilizes the opening and closing motion of the upper mold plate to convert the horizontal sliding power of the inner core-pulling seat into the driving force of the drive rod. This design eliminates the need for an additional independent driver, simplifying the mold structure, reducing the number of parts and space occupied. The tilted drive method achieves efficient power transmission, ensuring that the inner core-pulling action is synchronized with the opening and closing rhythm of the mold, thus improving production efficiency.

[0027] Specifically, the second limiting structure includes a second limiting block 17 detachably fixed to the lower template 2 by several bolts. The second limiting block 17 is inserted into the second limiting groove at the bottom of the inner core-pulling seat 14. The second limiting structure uses a detachable second limiting block to cooperate with the second limiting groove at the bottom of the inner core-pulling seat, providing a stable sliding guide for the inner core-pulling seat. The bolt connection facilitates later maintenance and adjustment, ensuring that the inner core-pulling seat does not shift during movement, and ensuring precise cooperation between the inner core block and the molding cavity. This design improves the movement accuracy of the inner core-pulling mechanism, reduces product defects caused by guide deviation, and improves molding quality.

[0028] Specifically, the inclined ejection mechanism includes an outer inclined ejector assembly 18 corresponding to the outer core block 9 and an inner inclined ejector assembly 19 corresponding to the inner core block 15. When ejecting the product under the drive of the top plate 7, the outer inclined ejector assembly 18 can move obliquely upward away from the outer core block 9, and the inner inclined ejector assembly 19 can move obliquely upward away from the inner core block 15. The inclined ejection mechanism, with the outer and inner inclined ejector assemblies respectively corresponding to the outer and inner core blocks, achieves oblique upward ejection away from the core blocks under the drive of the top plate. This ejection method can effectively avoid interference or adhesion between the product and the core block during the ejection process, ensuring smooth demolding. The bidirectional inclined ejector design makes the product subjected to uniform force, reduces ejection deformation, and improves the product molding accuracy and appearance quality.

[0029] Specifically, the outer inclined ejector assembly 18 includes several outer inclined ejector blocks 20 arranged along the inner edge of the outer core block 9. The outer inclined ejector blocks 20 are connected to the top plate 7 via outer inclined ejector rods, and the upper ends of the outer inclined ejector rods are inclined away from the outer core block 9. The inner inclined ejector assembly 19 includes several inner inclined ejector blocks 21 arranged along the inner edge of the inner core block 15. The inner inclined ejector blocks 21 are connected to the top plate 7 via inner inclined ejector rods, and the upper ends of the inner inclined ejector rods are inclined away from the inner core block 15. The outer inclined ejector assembly, through the cooperation of the outer inclined ejector blocks arranged along the inner edge of the outer core block and the inclined outer inclined ejector rods, and the inner inclined ejector assembly, through the cooperation of the inner inclined ejector blocks arranged along the inner edge of the inner core block and the inclined inner inclined ejector rods, achieves precise ejection of the inner and outer sides of the product. The multi-inclined ejector block layout ensures uniform distribution of ejection force, avoiding localized stress concentration that could damage the product. The inclined ejector rod design ensures that the ejection direction matches the product's demolding trajectory, further improving demolding smoothness and product qualification rate.

[0030] Specifically, the lifting mechanism 6 includes four lifting cylinders 22 fixed to the sides of the lower template 2, and the output shaft ends of the lifting cylinders 22 are connected to the top plate 7. The lifting mechanism uses four side-fixed lifting cylinders to drive the top plate, achieving smooth lifting and lowering of the top plate. The synchronous drive of multiple cylinders ensures balanced force on the top plate, avoiding tilting or jamming during the ejection process, ensuring consistent action of the inclined ejection mechanism, and the cylinder drive method provides sufficient power and controllable stroke, adapting to the ejection requirements of different product specifications, improving the versatility and operational stability of the mold, and reducing production stoppages caused by ejection failures.

[0031] The working principle of this utility model is as follows: the mold symmetrically sets two forming cavities between the upper and lower mold plates, and sets an upper and lower stacked external core pulling mechanism on the outside of the forming cavity and an internal core pulling mechanism on the inside, so as to achieve a compact layout of the core pulling mechanism. The upper and lower stacked design replaces the traditional external structure, which greatly reduces the space occupied by the mold. At the same time, with the inclined ejection mechanism on the top plate, the product is stably ejected, improving the overall integration and space utilization of the mold. The stacked external core-pulling mechanism adopts an integrated design of the external core-pulling base and the external core block. A translational driver is embedded in the driver mounting slot of the lower mold plate, achieving a built-in driver layout. An L-shaped connecting plate connects the translational driver and the external core-pulling base, ensuring stable transmission of driving power. This structure avoids the problem of traditional external drivers occupying extra space. Simultaneously, the sliding assembly ensures precise and smooth external core-pulling action, improving core-pulling efficiency and mold operation stability. The first limiting structure, through a detachable first limiting block, cooperates with the first limiting groove at the bottom of the external core-pulling base to form a precise sliding guide. The bolt connection facilitates the use of the limiting block. The installation and replacement of the outer core-pulling seat ensures that it moves along a fixed trajectory during translation, avoiding deviation or shaking. This design improves the motion accuracy of the outer core-pulling mechanism, ensures precise docking between the outer core block and the molding cavity, reduces mold wear, and extends service life. The outer limit block on the side of the lower template is set on the outside of the outer core-pulling seat to form the limit position constraint of the outer core-pulling action. This structure can effectively limit the maximum translation distance of the outer core-pulling seat, avoid damage to the mechanism or affect subsequent mold closing actions due to excessive core pulling. The mechanical limit ensures the consistency of the core-pulling stroke, improves the safety and reliability of mold operation, and reduces debugging and maintenance costs. The internal core-pulling mechanism adopts a combination design of an internal core-pulling seat and an internal core block. Sliding guidance is achieved through a second limiting structure, and power is provided by the driving structure of the upper mold plate. This design allows the internal and external core-pulling mechanisms to be positioned opposite each other, forming bidirectional precise control of the molding cavity. This avoids the problem of insufficient product molding accuracy caused by traditional single-sided core pulling. Simultaneously, the internal core-pulling mechanism is integrated inside the mold, further optimizing the spatial layout and improving the overall compactness of the mold. The driving structure is slidably connected to the internal core-pulling seat via a drive rod tilted and fixed to the bottom of the upper mold plate. The opening and closing motion of the upper mold plate is converted into horizontal sliding power for the internal core-pulling seat. This design eliminates the need for additional... An independent external drive simplifies the mold structure, reduces the number of parts and space occupied, and the tilting drive achieves efficient power transmission, ensuring that the inner core pulling action is synchronized with the mold opening and closing rhythm, thus improving production efficiency. The second limit structure uses a detachable second limit block to cooperate with the second limit groove at the bottom of the inner core pulling seat, providing a stable sliding guide for the inner core pulling seat. The bolt connection facilitates later maintenance and adjustment, ensuring that the inner core pulling seat does not deviate during movement and ensuring precise cooperation between the inner core block and the molding cavity. This design improves the motion accuracy of the inner core pulling mechanism, reduces product defects caused by guide deviation, and improves molding quality. The inclined ejection mechanism uses an outer inclined ejector assembly and an inner inclined ejector assembly corresponding to the outer and inner core blocks, respectively. Driven by the top plate, it ejects the product obliquely upwards away from the core block. This ejection method effectively avoids interference or adhesion between the product and the core block during ejection, ensuring smooth demolding. The bidirectional inclined ejector design ensures uniform force distribution on the product, reduces ejection deformation, and improves product molding accuracy and appearance quality. The outer inclined ejector assembly uses an outer inclined ejector block set along the inner edge of the outer core block and an inclined outer inclined ejector rod to cooperate. The inner inclined ejector assembly uses an inner inclined ejector block set along the inner edge of the inner core block and an inclined inner inclined ejector rod to cooperate, achieving precise pushing of the product's inner and outer sides. The multi-inclined ejector block layout ensures uniform ejection force distribution, avoiding localized stress concentration that could damage the product. The inclined ejector rod design ensures that the ejection direction matches the product's demolding trajectory, further improving demolding smoothness and product yield. The lifting mechanism uses four side-fixed lifting cylinders to drive the top plate, achieving smooth lifting and lowering of the top plate. The synchronous drive of multiple cylinders ensures balanced force on the top plate, avoiding tilting or jamming during the ejection process, ensuring consistent action of the inclined ejection mechanism. The cylinder drive method has sufficient power and controllable stroke, adapting to the ejection requirements of different product specifications, improving the versatility and operational stability of the mold, and reducing production stoppages caused by ejection failures.
