Description

Technical Field

[0001] This invention relates to the field of injection mold technology, and in particular to an injection mold and its processing method. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Injection molding requires the use of injection molds, which are divided into upper molds and lower molds. The lower mold is fixed in position, and the assembly and separation of the upper and lower molds are achieved by using an assembly robot arm, thereby realizing the injection molding of parts.

[0003] However, for existing injection molds, the assembly pressure of the assembly robot arm lacks a limit and adjustment structure, making it unable to adapt to the assembly of different types of injection molds. Excessive assembly pressure can easily cause the injection mold to crack and be damaged, while insufficient assembly pressure can lead to leakage during the injection molding process. It has poor flexibility and adaptability, and is not very practical. Summary of the Invention

[0004] In view of this, the present invention provides an injection mold and processing method, which has an assembly component. The assembly component can be moved by an assembly robot arm, thereby realizing the assembly and separation of mold components. During assembly, the assembly component can limit the maximum assembly pressure of the mold components, thereby avoiding the phenomenon of mold component breakage due to excessive assembly pressure. It is stable in use and can also ensure that the mold components can be stably assembled without leakage. The maximum assembly pressure of the assembly component can be freely adjusted, so it can be adapted to the assembly and injection molding of different types of mold components. It has extremely high flexibility, adaptability and practicality.

[0005] This invention provides an injection mold and a processing method, specifically including: a mold assembly, the mold assembly including an upper mold and a lower mold, the lower mold being fixedly installed on an injection molding worktable, and the upper mold being inserted into the top of the lower mold; a connecting assembly, the connecting assembly including a connecting plate, a mounting column, an adjusting rod, and a trigger seat, the bottom of the connecting plate being fixedly installed on the top of the upper mold, and the mounting column being fixedly installed on the top of the connecting plate, the adjusting rod being rotatably connected inside the mounting column, and the trigger seat being inserted into the inside of the mounting column; and an assembly assembly, the assembly assembly including an electric push rod, a pressure plate, a synchronizing rod, and a control rod, the top of the electric push rod being fixedly installed on an assembly robot arm, and the push rod of the electric push rod being inserted into the inside of the pressure plate, the pressure plate being inserted into the inside of the mounting column, the synchronizing rod being inserted laterally into the inside of the pressure plate, and the control rod being inserted longitudinally into the bottom of the pressure plate, with the bottom end of the control rod protruding from the inside of the pressure plate.

[0006] Furthermore, a pressure spring is provided at the bottom of the pressure plate, and the two ends of the pressure spring abut against the bottom of the pressure plate and the top of the connecting plate, respectively.

[0007] Furthermore, the electric push rod has a synchronous tooth groove inside, and a synchronous locking block is provided on the side of the synchronous rod. The synchronous locking block is inserted into the synchronous tooth groove. The cross-sectional shape of the synchronous locking block and a single tooth groove of the synchronous tooth groove is a right triangle. When the push rod of the electric push rod moves down, the straight edge of the block of the synchronous locking block and the straight edge of the tooth groove of the synchronous tooth groove engage with each other.

[0008] Furthermore, the synchronizer rod has a synchronizer top spring inside its body, and the two ends of the synchronizer top spring abut against the inside of the synchronizer rod and the inside of the pressure plate, respectively.

[0009] Furthermore, the pressure plate is I-shaped, and the mounting column has a track groove inside, into which the pressure plate is inserted.

[0010] Furthermore, the synchronous rod has an inclined stress relief groove inside its body, and the control rod has a stress relief rod on its side. The stress relief rod is inserted into the stress relief groove, and the control rod is located above the trigger seat.

[0011] Furthermore, the adjusting rod has threads on its outer surface, and the adjusting rod is screwed into the inside of the trigger seat through the rod thread.

[0012] Furthermore, the mounting column, adjusting rod, trigger seat, synchronizing rod, and control rod constitute a pressure control mechanism, and there are two sets of pressure control mechanisms. The two sets of pressure control mechanisms are symmetrically installed on both sides of the electric push rod, and the bottoms of the two adjusting rods are connected by sprockets and chain drives. Beneficial effects

[0013] 1. When in use, this device uses an assembly robotic arm to move assembly components, thereby enabling the assembly and separation of mold components. During assembly, the device limits the maximum assembly pressure of the mold components, preventing excessive pressure from causing breakage or damage. It is stable in use and ensures stable assembly between mold components without leakage. The maximum assembly pressure of the assembly components can be freely adjusted, making it suitable for injection molding of different types of mold components. This improves the flexibility, adaptability, and practicality of the device.

[0014] 2. The assembly robot arm can move the assembly components. When the assembly components are driven by the assembly robot arm, the pressure plate can drive the connecting components to move synchronously. Since the upper mold is fixed at the bottom of the connecting plate, the upper mold can also move synchronously to achieve assembly with the lower mold. The operation is flexible and convenient. When the upper mold is installed on the top of the lower mold, the extension of the electric push rod can drive the pressure plate to move down synchronously to compress the pressure spring, thereby applying assembly pressure to the mold assembly. When the electric push rod extends downward, the synchronous locking block is inserted into the synchronous tooth groove under the action of the synchronous top spring. When the electric push rod extends downward, the synchronous tooth groove and the straight edge of the synchronous locking block are engaged, so the electric push rod can drive the pressure plate to move down synchronously to compress the pressure spring. After being compressed, the pressure spring can apply assembly pressure to the upper mold, thereby achieving stable assembly and use of the mold assembly. The operation is convenient.

[0015] 3. This device can limit the maximum assembly pressure of the mold components, ensuring that the assembly pressure between the mold components is at an optimal level and guaranteeing stable injection molding quality. When the assembly pressure is less than the set pressure, the control lever will not contact the trigger seat as it moves downward with the pressure plate, thus preventing the pressure limit function from being triggered. When the assembly pressure of the mold components reaches the limit value, the control lever will be blocked by the trigger seat as it continues to move downward with the pressure plate, preventing it from continuing to move downward with the pressure plate. Furthermore, if the pressure plate continues to move downward, the control lever will be lifted by the trigger seat. During the process of the control rod being lifted, the unloading rod can drive the synchronizing rod to move laterally through the unloading groove. After the synchronizing rod moves laterally, the synchronizing block disengages from the inside of the synchronizing tooth groove. Subsequently, the pressure spring will drive the pressure plate to move upward to unload the force. After the pressure plate moves upward by one tooth groove distance, the synchronizing rod and control rod can automatically reset under the action of the synchronizing spring, restoring the state of the synchronizing block being inserted into the synchronizing tooth groove. Even if the push rod of the electric push rod continues to move downward afterward, the assembly component will cyclically trigger the limit function, thereby ensuring that the maximum assembly pressure of the mold component will not exceed the limit value, and the use is stable.

[0016] 4. The maximum assembly pressure limit of this device can be freely adjusted by the adjusting rod, which can be used to assemble different types of mold components. When the adjusting rod is rotated, the adjusting rod can drive the trigger seat to move up and down inside the mounting column to change the position, thereby changing the compression degree of the pressure spring when the assembly component triggers the limit function, that is, changing the maximum assembly pressure of the mold component, which is highly adaptable.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0022] Example: Please refer to Figures 1 to 10 As shown: This invention provides an injection mold and a processing method, including a mold assembly 1, which includes an upper mold 101 and a lower mold 102. The lower mold 102 is fixedly mounted on an injection molding worktable, and the upper mold 101 is inserted into the top of the lower mold 102. A connecting assembly 2 includes a connecting plate 201, a mounting post 202, an adjusting rod 203, and a trigger seat 204. The bottom of the connecting plate 201 is fixedly mounted on the top of the upper mold 101, and the mounting post 202 is fixedly mounted on the top of the connecting plate 201. The adjusting rod 203 is rotatably connected inside the mounting post 202. The trigger seat 204 is inserted into the interior of the mounting post 202; the assembly assembly 3 includes an electric push rod 301, a pressure plate 302, a synchronizing rod 303, and a control rod 304. The top of the electric push rod 301 is fixedly mounted on the assembly robot arm, and the push rod of the electric push rod 301 is inserted into the interior of the pressure plate 302. The pressure plate 302 is inserted into the interior of the mounting post 202, and the synchronizing rod 303 is inserted laterally into the interior of the pressure plate 302. The control rod 304 is inserted longitudinally into the bottom of the pressure plate 302, and the bottom end of the control rod 304 protrudes into the interior of the pressure plate 302.

[0023] The electric push rod 301 and the assembly robot arm are electrically connected to an external power source and control device. Their specific structure and working principle are existing mature technologies and will not be described in detail here.

[0024] The pressure plate 302 has a pressure spring 3021 at its bottom, with both ends of the pressure spring 3021 abutting against the bottom of the pressure plate 302 and the top of the connecting plate 201, respectively. In use, the assembly robot arm can move the assembly component 3. When the assembly component 3 is moved by the assembly robot arm, the pressure plate 302 can move the connecting component 2 synchronously. Since the upper mold 101 is fixed to the bottom of the connecting plate 201, the upper mold 101 can also move synchronously to achieve assembly with the lower mold 102. The operation is flexible and convenient. When the upper mold 101 is installed on top of the lower mold 102, the extension of the electric push rod 301 can drive the pressure plate 302 to move synchronously downwards to compress the pressure spring 3021, thereby applying assembly pressure to the mold component 1. The push rod of the electric push rod 301 has a synchronous toothed groove 3011 inside, and the side of the synchronous rod 303... The surface is provided with a synchronous locking block 3031, which is inserted into the inside of the synchronous tooth groove 3011. The cross-sectional shape of each tooth groove of the synchronous locking block 3031 and the synchronous tooth groove 3011 is a right-angled triangle. When the push rod of the electric push rod 301 moves down, the straight edge of the block of the synchronous locking block 3031 and the straight edge of the tooth groove of the synchronous tooth groove 3011 engage with each other. When the electric push rod 301 extends downward, the synchronous locking block 3031 is inserted into the inside of the synchronous tooth groove 3011 under the action of the synchronous top spring 3032. When the electric push rod 301 extends downward, the straight edge of the synchronous tooth groove 3011 and the synchronous locking block 3031 engage. Thus, the electric push rod 301 can drive the pressure plate 302 to move down synchronously and compress the pressure top spring 3021. After being compressed, the pressure top spring 3021 can apply assembly pressure to the upper mold 101, thereby realizing the stable assembly and use of the mold assembly 1 and making the operation convenient.

[0025] The pressure plate 302 is I-shaped, and the mounting column 202 has a track groove 2021 inside. The pressure plate 302 is inserted into the track groove 2021. During use, the track groove 2021 can restrict the movement trajectory of the pressure plate 302, so that the pressure plate 302 will not be tilted or twisted during movement, which would cause the device to jam and fail, and the use is stable.

[0026] The synchronizing rod 303 has an inclined pressure relief groove 3033 inside its body, and the control rod 304 has a pressure relief rod 3041 on its side. The pressure relief rod 3041 is inserted into the pressure relief groove 3033, and the control rod 304 is located above the trigger seat 204. In use, this device can limit the maximum assembly pressure of the mold assembly 1, so that the assembly pressure between the mold assemblies 1 can be in the optimal state, ensuring the stability of the injection molding quality. When the assembly pressure is less than the set pressure, the control rod 304 will not contact the trigger seat 204 when it moves downward with the pressure plate 302, thus not triggering the pressure limiting function. When the assembly pressure of the mold assembly 1 reaches the limit value, the control rod 304 will be blocked by the trigger seat 204 when it continues to move downward with the pressure plate 302, so the control rod 304 will not continue to move downward with the pressure plate 302. After that, the control rod 304 will be triggered when the pressure plate 302 continues to move downward. When seat 204 is lifted, during the process of control rod 304 being lifted, unloading rod 3041 can drive synchronous rod 303 to move laterally through unloading groove 3033. After synchronous rod 303 moves laterally, synchronous locking block 3031 disengages from inside synchronous tooth groove 3011. Subsequently, pressure spring 3021 will drive pressure plate 302 to move upward to unload. Synchronous spring 3032 is provided inside the rod body of synchronous rod 303, and the two ends of synchronous spring 3032 abut against the inside of synchronous rod 303 and pressure plate 302 respectively. After pressure plate 302 moves upward one tooth distance of synchronous tooth groove 3011, synchronous rod 303 and control rod 304 can automatically reset and restore synchronous locking block 3031 to the state of being inserted into synchronous tooth groove 3011 under the action of synchronous spring 3032. Even if the push rod of electric push rod 301 continues to move downward, assembly component 3 will cyclically trigger limit function, thereby ensuring that the maximum assembly pressure of mold component 1 will not exceed the limit value and the operation is stable.

[0027] The adjusting rod 203 has threads on its outer surface and is screwed into the trigger seat 204 via these threads. During use, the maximum assembly pressure limit of this device can be freely adjusted via the adjusting rod 203, adapting to the assembly of different types of mold components 1. When the adjusting rod 203 is rotated, it causes the trigger seat 204 to move up and down within the mounting post 202, changing its position. This alters the compression degree of the pressure spring 3021 during the trigger limit function of the assembly component 3, thus changing the maximum assembly pressure of the mold component 1. With extremely high adaptability, the mounting column 202, adjusting rod 203, trigger seat 204, synchronizing rod 303, and control rod 304 form a pressure control mechanism. There are two sets of pressure control mechanisms, which are symmetrically installed on both sides of the electric push rod 301. The bottoms of the two adjusting rods 203 are connected by a sprocket and chain drive. The design of the two sets of pressure control mechanisms allows the pressure plate 302 to move up and down stably. Under the action of the sprocket and chain, rotating any one of the adjusting rods 203 can adjust the overall position of the two trigger seats 204, further improving the stability of the device.

[0028] The specific usage and function of this embodiment: In this invention, the maximum assembly pressure limit value of mold assembly 1 is adjusted according to actual processing requirements. The maximum assembly pressure limit value can be freely adjusted by adjusting rod 203, which can adapt to the assembly of different types of mold assembly 1. When adjusting rod 203 is rotated, it can drive trigger seat 204 to move up and down inside mounting column 202 to change its position, thereby changing the compression degree of pressure spring 3021 when assembly assembly 3 triggers the limit function, that is, changing the maximum assembly pressure of mold assembly 1. The assembly robot arm can drive assembly assembly 3 to move. When assembly assembly 3 is driven by the assembly robot arm, it can drive connecting assembly 2 to move synchronously through pressure plate 302. Since the upper mold 101 is fixed to the bottom of the connecting plate 201, the upper mold 101 can also move synchronously to achieve assembly and use with the lower mold 102. The operation is flexible and convenient. When the upper mold 101 is installed on the top of the lower mold 102, the extension of the electric push rod 301 can drive the pressure plate 302 to move down synchronously and compress the pressure spring 3021, thereby applying assembly pressure to the mold assembly 1. When the electric push rod 301 extends downward, under the action of the synchronous spring 3032, the synchronous locking block 3031 is inserted into the inside of the synchronous tooth groove 3011. When the electric push rod 301 extends downward, the straight edge of the synchronous tooth groove 3011 and the synchronous locking block 3031 engages, so the electric push rod 301 can drive the pressure plate 302 to move down synchronously and compress the pressure spring 3021. 021, the pressure spring 3021, after being compressed, can apply assembly pressure to the upper mold 101, thereby achieving stable assembly and use of the mold assembly 1. This device can limit the maximum assembly pressure of the mold assembly 1, ensuring that the assembly pressure between the mold assemblies 1 is in the optimal state, thus guaranteeing the stability of the injection molding quality. When the assembly pressure is less than the set pressure, the control rod 304 will not contact the trigger seat 204 when it moves downward with the pressure plate 302, thus not triggering the pressure limiting function. When the assembly pressure of the mold assembly 1 reaches the limit value, the control rod 304 will be blocked by the trigger seat 204 when it continues to move downward with the pressure plate 302, thus preventing the control rod 304 from continuing to move downward with the pressure plate 302. As the force plate 302 continues to move downwards, the control rod 304 is lifted by the trigger seat 204. During the lifting process, the unloading rod 3041 can drive the synchronizing rod 303 to move laterally through the unloading groove 3033. After the synchronizing rod 303 moves laterally, the synchronizing block 3031 disengages from the interior of the synchronizing tooth groove 3011. Subsequently, the pressure spring 3021 will drive the pressure plate 302 to move upwards to unload the force. After the pressure plate 302 moves upwards by one tooth distance from the synchronizing tooth groove 3011, the synchronizing rod 303 and the control rod 304 can automatically reset and restore the state of the synchronizing block 3031 inserted into the synchronizing tooth groove 3011 under the action of the synchronizing spring 3032. Even if the push rod of the electric push rod 301 continues to move downwards, the assembly component 3 will cyclically trigger the limit function.This ensures that the maximum assembly pressure of mold component 1 will not exceed the limit. After mold component 1 is assembled, injection molding can begin. After injection molding is completed, the assembly robot arm moves assembly component 3 upward to release the assembly relationship of mold component 1, allowing the injection-molded parts to be removed. Under the weight of assembly component 3, connecting component 2, and upper mold 101, assembly component 3 can return to its reset state. During this process, the inclined edges of the synchronous locking block 3031 and synchronous tooth groove 3011 squeeze and avoid each other, preventing assembly component 3 from jamming and failing to reset. Afterward, the electric push rod 301 is controlled to retract and reset, ready for the next assembly and injection molding of mold component 1.
