Description

Technical Field

[0001] The present invention relates to the technical field of injection molding machines, and particularly to an injection molding machine template that is convenient for accurate docking. Background Art

[0002] In the field of injection molding, the injection molding machine template is an important part of the injection molding machine, and its mold clamping accuracy and docking stability directly affect the molding quality of injection products. In the existing injection molding technology, during the splicing and mold clamping process of the injection molding machine template, it often relies on manual alignment and positioning. This method has the following defects and deficiencies: During the splicing process of the existing injection molding machine template, direct guide post positioning or a simple snap - fit structure is usually adopted, lacking automatic guiding and locking functions. When the templates are docked, due to assembly position errors or external force interference, the templates are prone to misalignment or deviation, affecting the mold clamping accuracy and reducing the consistency and molding quality of injection products.

[0003] During the injection molding process, the template needs to withstand a high - temperature and high - pressure working environment, and the opening and closing of the mold during the injection molding process will generate periodic vibrations and impacts. The splicing structure of the existing injection molding machine template mostly adopts screw or snap - fastener fixing methods, lacking a self - locking function, and is prone to loosening of the splicing or deformation of the connection part due to vibration or load changes, affecting the injection molding accuracy and molding quality.

[0004] During the splicing and disassembly process of the existing injection molding machine template, manual assistance for positioning and fixing is usually required, and the positioning position needs to be frequently adjusted during the operation process. The operation steps are cumbersome, the positioning accuracy is poor, affecting the injection molding production efficiency and increasing the labor intensity.

[0005] During the splicing process of the existing injection molding machine template, there is often a lack of limiting and locking devices, and it is prone to loosening or separation of the splicing structure due to operation errors or mechanical vibrations, resulting in poor structural stability and potential operation safety hazards, and it is difficult to meet the requirements for stability and safety in the modern injection molding production process. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

The number of the splicing components is two groups and they are respectively fixed on the opposite surfaces of the template base and the injection molding machine template. The pressing fasteners and the lock - catch plates are arranged in one - to - one correspondence and opposite to each other; The splicing assembly includes a sliding sleeve seat, a main toothed disc, a guide rack and a coil spring located on the inner side of the main toothed disc, the axis of the coil spring is fixed to the inner side of the sliding sleeve seat, a pulley is provided on the surface of the guide rack for slidingly abutting against the inner wall of the sliding sleeve seat, one side of the guide rack is provided with a spur tooth surface meshing with the surface of the main toothed disc for transmission, and the spur tooth surface is arranged obliquely, a rubber buckle wheel is rotatably mounted on one end of the guide rack, and a buckle groove matching the rubber buckle wheel is provided on the surface of the main toothed disc.

[0008] Preferably, the buckle comprises a fixed seat and an axial pin rod rotatably installed on the inner side of the fixed seat, the surface of the axial pin rod is sleeved with a torsion spring, and the other end of the torsion spring is fixedly connected to the inner side of the fixed seat, one end of the axial pin rod is provided with a convex locking disk, the surface of the convex locking disk is provided with a coupling groove, the surface of the locking disk is provided with a convex buckle piece, and the shape and size of the convex buckle piece are adapted to the coupling groove.

[0009] Preferably, the cam lock plate is in a conical disk shape, one side of the cam buckle plate is an inclined surface, and the engagement groove is arranged in a spiral direction, so as to guide the deflection movement of the shaft pin rod when the cam lock plate is against the surface of the locking buckle plate.

[0010] Preferably, a self-locking structure is formed between the convex locking disk and the locking plate by a torsion spring, and during the mold closing process, the passive deflection and automatic reset between the convex locking disk and the locking plate are achieved through the elastic reset effect of the torsion spring.

[0011] Preferably, the coil spring is fixedly connected to the main gear disc via a snap-in groove structure, the coil spring forms energy storage through elastic compression during the splicing process, and the main gear disc is reset and rotated by the coil spring after disassembly.

[0012] Preferably, the rubber buckle wheel is a rubber component, and when the two splicing components are in a spliced ​​state, the outer periphery of the rubber buckle wheel is in interference contact with the inner side of the buckle groove.

[0013] Preferably, the guide rack is connected to the main gear disc via a toothed meshing structure, and the surface pulley of the guide rack slides smoothly along the inner side of the sliding sleeve seat.

[0014] Preferably, the coil spring is in a planar spiral shape, and in a natural state during the non-splicing process so that the guide rack lead-out sleeve seat reaches a maximum elongation, and in the splicing state, the coil spring is in a compressed force storage state.

[0015] Preferably, the telescopic rod is an elastic piston rod structure, which is used to provide elastic tension when the template seat and the injection molding machine template are in a docking state, so as to keep the shaft pin rod in frictional contact with the inner side of the convex buckle piece.

[0016] At the beginning of splicing, the spiral spring remains in a naturally stretched state, and the guide rack is in a state of extending out of the sliding sleeve seat. Through manual or lifting equipment, the two templates are gradually moved closer, and the outer tooth surface of the guide rack inside one of the sliding sleeve seats in the two splicing components meshes with the toothed structure on the main toothed disc inside the other sliding sleeve seat to form a guiding effect.

[0017] During the splicing process, the guide rack slides along the guide groove of the sliding sleeve seat and drives the main toothed disc to rotate until the buckle groove on the surface of the main toothed disc contacts the rubber buckle wheel, forming a self-locking state, ensuring that the two splicing components are in a locked state and the locking disc and the fastener are in a relative position.

[0018] During the locking process, the surface of the injection molding machine template is pressed vertically to close the template seat and the injection molding machine template, the telescopic rod retracts elastically, and the pressing part moves closer to the lock plate. The surface engagement groove of the convex lock plate is in passive contact with the convex buckle piece on the lock plate, and the convex lock plate is passively deflected by the spiral structure of the engagement groove, the torsion spring is twisted by energy storage, and the surface engagement groove of the convex lock plate is engaged with the convex buckle piece on the lock plate, so that the convex lock plate can enter the interior of the lock plate.

[0019] In the locked state, the docking distance and position between the template seat and the injection molding machine template are accurately locked to prevent displacement or loosening during the subsequent injection molding process.

[0020] During the splicing process, the guide rack forms a guiding fit with the surface of the sliding sleeve seat through the pulley. During the rotation of the main gear plate, the guide rack slides smoothly along the surface of the sliding sleeve seat. The pulley on the surface of the guide rack forms a limit fit on the inside of the sliding sleeve seat to prevent the guide rack from lateral displacement or dislocation during the splicing process, ensuring the accuracy and stability of the template docking.

[0021] After the splicing is completed, the buckle piece maintains a stable locking state through the meshing structure between the convex locking plate and the locking plate. Since the engagement groove is a spiral structure, when the convex locking plate and the locking plate are subjected to external force, the spiral structure can convert the external force into the deflection force of the shaft pin rod to prevent the convex locking plate from loosening due to vibration or impact.

[0022] When the template needs to be removed, the cam lock plate is rotated along the spiral groove direction by external force to release the locking state. The guide rack is withdrawn from the inner side of the main gear plate by external force, and the spiral spring restores the main gear plate to its initial position under the elastic force. After the guide rack is completely separated from the main gear plate, the connection between the template seat and the injection molding machine template is completely released, and the template removal operation is completed.

[0023] The present invention realizes automatic positioning and locking during the splicing and disassembly of the injection molding machine template through the linkage structure design between the splicing components and the pressing fasteners, thereby improving the splicing accuracy and stability of the injection molding machine template, effectively preventing the template from being displaced or loosened during the injection molding process, and ensuring the molding accuracy of the injection molded workpiece.

[0024] The beneficial effects achieved by the present invention are as follows: 1. In the present invention, by providing a splicing assembly including a main gear disc, a guide rack, and a spiral spring, during the docking process between the template base and the injection molding machine template, the tooth-shaped meshing transmission structure between the guide rack and the main gear disc can realize automatic guidance and self-locking positioning during the splicing process, prevent misalignment or deviation during the splicing process, and significantly improve the accuracy and stability of the template docking.

[0025] 2. In the present invention, after the splicing is completed, a locking structure is formed between the convex lock disc and the lock catch disc through the engagement groove and the convex catch piece, which can enhance the seismic and impact resistance performance of the splicing structure when subjected to vibration or load changes, prevent the splicing from loosening, and improve the safety and reliability of the equipment operation.

[0026] 3. In the present invention, through the cooperation between the spiral spring, the pulley, and the guide rack, during the splicing and disassembly of the template, the template can realize rapid alignment during splicing and stable reset during disassembly through the sliding guidance between the main gear disc and the guide rack, reduce the difficulty of manual operation, and improve the convenience of splicing and disassembly.

Specific embodiments

[0029] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0030] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0031] The following combines the attached Figures 1 to 8 Describe an injection molding machine template that is convenient for accurate docking provided by some embodiments of the present invention.

[0032] Embodiment 1 The present invention relates to an injection molding machine template that is convenient for accurate docking, and specifically includes a template base 100, an injection molding machine template 200, a splicing component 300, a locking disk 110, a telescopic rod 210, and a pressing fastener 400. Among them, the template base 100 and the injection molding machine template 200 are quickly docked and locked through the splicing component 300 and the pressing fastener 400.

[0033] The splicing component 300 includes a sliding sleeve seat 310, a main gear disk 320, a guide rack 330, and a helical spring 340 arranged inside the main gear disk 320. The sliding sleeve seat 310 is installed on the opposite surfaces of the template base 100 and the injection molding machine template 200. The guide rack 330 forms a sliding guiding connection with the sliding sleeve seat 310 through a pulley 332. The straight tooth surface on the surface of the guide rack 330 meshes with the tooth-shaped structure on the main gear disk 320 to form a transmission structure. A buckling groove 321 is provided on the surface of the main gear disk 320, and the buckling groove 321 cooperates with the rubber buckle wheel 331 at the end of the guide rack 330 to form a self-locking state. The helical spring 340 is fixedly connected to the main gear disk 320 through a clamping groove structure, forms elastic compression energy storage during the splicing process, and realizes the reset of the main gear disk 320 through elastic force rebound during the disassembly process.

[0034] Latch Disc 110 and Fastening Component 400: The latch disc 110 and the fastening component 400 are respectively installed on the opposite surfaces of the template base 100 and the injection molding machine template 200. The surface of the latch disc 110 is provided with a protruding buckle piece 111, which cooperates with the engaging groove 422 of the protruding lock disc 421 on the fastening component 400. The fastening component 400 includes a fixed seat 410, a pin rod 420, and a torsion spring 430. The protruding lock disc 421 is rotatably connected to the fixed seat 410 through the pin rod 420, and the torsion spring 430 provides locking and reset functions.

[0035] Embodiment 2: Automatic Control for Assembly and Disassembly This embodiment provides an automatic control system for improving the accuracy and efficiency of template docking and disassembly. In this embodiment, an automatic control device is introduced during the assembly process of the template base 100 and the injection molding machine template 200, enhancing the overall assembly stability and reliability.

[0036] 1. Initial Positioning and Assembly Process of the Template: Before assembly, the template base 100 and the injection molding machine template 200 are precisely positioned through an automatic control device. The two templates are butted in parallel through an electric push rod or a hydraulic drive system, and a laser positioning system is used to precisely correct the assembly position of the templates. The system fine-tunes the position of the template by controlling the drive device according to the detected template position to ensure the precise docking of the assembly component 300.

[0037] 2. Automatic Locking of the Assembly Component 300: The automatic system controls the connection process of the assembly component 300 through a real-time feedback mechanism. The meshing of the guide rack 330 and the main gear disc 320 no longer depends on manual adjustment. The system determines whether the guide rack 330 and the main gear disc 320 are fully docked according to the sensor signal to ensure that each assembly reaches the optimal position. During the meshing process, the rubber buckle wheel 331 and the buckle groove 321 are perfectly matched to complete self-locking.

[0038] 3. Automatic Locking of the Latch Disc 110 and the Fastening Component 400: When the template base 100 and the injection molding machine template 200 start to dock, the automatic control device precisely docks the latch disc 110 and the fastening component 400. The fastening component 400 is controlled to approach the latch disc 110 through an electromagnetic valve and a pneumatic device, and the protruding lock disc 421 and the engaging groove 422 form a precise fit to complete locking.

[0039] 4. Limitation and Stability Maintenance of the Guide Rack 330: During the sliding process of the guide rack 330, under the control of the automatic system, the pulley 332 always slides along the inner wall of the sliding sleeve seat 310 to ensure the stable operation of the guide rack 330. This design further improves the smoothness and accuracy of the assembly process.

[0040] Furthermore, in this embodiment, the guiding system during the splicing process is optimized, and a loosening prevention protection design is additionally provided, improving the stability and safety of the template during the operation of the injection molding machine.

[0041] In this embodiment, when the template base 100 and the injection molding machine template 200 are initially docked, a laser docking system is used. This system can detect the real-time position and error of the template, and automatically adjust the distance between the template base 100 and the injection molding machine template 200 through a fine-tuning driving device to ensure parallel docking of the two templates.

[0042] To prevent the template from loosening under high-pressure working conditions after splicing, a dual locking mechanism is designed in this embodiment. Between the splicing component 300 and the locking disc 110, in addition to the traditional spiral spring 340, a mechanical locking device is additionally provided. This device uses a sliding lock pin and a lock groove structure to ensure that the spliced template does not undergo any displacement or loosening.

[0043] This embodiment also improves the template disassembly process. When disassembling the template, the release of the spiral spring 340 and the torsion spring 430 is controlled by an electric motor, making the disassembly process faster and more stable. Through the operation of the automation device, the template base 100 and the injection molding machine template 200 can be accurately separated, avoiding possible misoperations during manual disassembly.

[0044] To improve the stability of the template, a shockproof design is added in this embodiment. The locking disc 110 and the pressing component 400 are buffered by wear-resistant elastic materials, reducing the impact of external vibrations on the locking structure and further strengthening the stability of the spliced template.

[0045] Embodiment 3: Modular Design and Expandability This embodiment provides an injection molding machine template structure with a modular design, facilitating users to customize and expand the template according to different requirements.

[0046] 1. Modular splicing component 300: Different from traditional fixed splicing components, this embodiment adopts a modular splicing component 300. Users can select main gear discs 320 and guide racks 330 of different specifications and types according to specific requirements. This design makes the injection molding machine template more adaptable and capable of being applied to different types of injection molding machines.

[0047] 2. Compatibility between the locking disc 110 and the pressing component 400: Between the locking disc 110 and the pressing component 400, various specifications and shapes of accessories are designed in this embodiment, enabling flexible combination of injection molding machine templates of different specifications. Users only need to select the corresponding accessories according to the requirements of the template, which provides great convenience for the customization and replacement of the template.

[0048] Through the design of multiple embodiments, the present invention has successfully achieved the rapid splicing, automatic positioning and locking of the injection molding machine template that is convenient for accurate docking, while providing higher stability and reliability. The innovative technologies such as automated control, intelligent auxiliary system, and modular design introduced in different embodiments have greatly expanded the application scope and practicality of the present invention. Through these designs, the present invention can meet the requirements of different injection molding machine equipment and ensure the stability and safety of the injection molding machine template in a high-load working environment.

[0049] The working principle and usage process of the present invention: The present invention relates to an injection molding machine template that is convenient for accurate docking. By setting up structures such as splicing components 300, locking disc 110, pressing components 400, and telescopic rods 210, the rapid docking, automatic positioning and locking of the injection molding machine template 200 are realized, improving the clamping accuracy and stability of the injection molding machine template 200 and preventing misalignment or loosening. Its complete working principle is as follows 1. Initial positioning and splicing process of the template Before splicing, the template base 100 and the injection molding machine template 200 are arranged parallel to each other, and two splicing components 300 are respectively set at the relative positions on the surfaces of the template base 100 and the injection molding machine template 200.

[0050] At the beginning of splicing, the spiral spring 340 maintains a natural stretched state, and the guide rack 330 is in an extended state on the surface of the sliding sleeve seat 310.

[0051] Through manual handling or the handling of lifting equipment, the two templates are gradually brought closer. Among the two relatively moving splicing components 300, the outer tooth surface of the guide rack 330 inside one sliding sleeve seat 310 meshes with the tooth-shaped structure on the main gear disc 320 inside the other sliding sleeve seat 310, forming a guiding effect.

[0052] 2. Docking and automatic locking of the splicing component 300 When the guide rack 330 and the main gear disc 320 form an initial meshing state, the connection between the two splicing components 300 begins to be gradually established: During the closing process of the template base 100 and the injection molding machine template 200, the guide rack 330 slides along the guide groove of the sliding sleeve seat 310 and drives the main gear disc 320 to rotate; Until the buckle groove 321 on the surface of the main gear disc 320 contacts the rubber buckle wheel 331, forming a self-locking state to ensure that the two splicing components 300 are in a locked state, and the locking disc 110 and the pressing component 400 are in a relative position.

[0053] 3. Automatic locking of the locking disc 110 and the pressing component 400 During the docking process of the template base 100 and the injection molding machine template 200, the locking disc 110 and the pressing component 400 are gradually docked: Press the surface of the vertical injection molding machine template 200 to close the template base 100 and the injection molding machine template 200. The telescopic rod 210 elastically retracts, and the buckle 400 approaches the locking disc 110.

[0054] The surface engaging groove 422 of the convex locking disc 421 is in passive contact with the convex buckle piece 111 on the locking disc 110, and the convex locking disc 421 is passively deflected by means of the spiral structure of the engaging groove 422. The torsion spring 430 stores energy and twists. The surface engaging groove 422 of the convex locking disc 421 meshes with the convex buckle piece 111 on the locking disc 110, enabling the convex locking disc 421 to enter the interior of the locking disc 110.

[0055] After the locking disc 110 enters, the pin rod 420 is guided to complete deflection and locking by means of the resilience of the torsion spring 430.

[0056] In the locked state, the docking distance and position between the template base 100 and the injection molding machine template 200 are accurately locked to prevent displacement or loosening during subsequent injection molding.

[0057] 4. Limitation and stability maintenance of the guide rack 330 During the splicing process, the guide rack 330 forms a guiding fit with the surface of the sliding sleeve base 310 through the pulley 332: During the rotation of the main gear disc 320, the guide rack 330 slides smoothly along the surface of the sliding sleeve base 310.

[0058] The pulley 332 on the surface of the guide rack 330 forms a limiting fit inside the sliding sleeve base 310 to prevent lateral offset or dislocation of the guide rack 330 during the splicing process, ensuring the accuracy and stability of the template docking.

[0059] 5. Locked state maintenance and anti-loosening effect After the splicing is completed, the buckle 400 maintains a stable locked state through the meshing structure between the convex locking disc 421 and the locking disc 110: Since the engaging groove 422 is of a spiral structure, when the convex locking disc 421 and the locking disc 110 are subjected to external forces, the external forces can be converted into the deflection force of the pin rod 420 through the spiral structure, preventing the convex locking disc 421 from loosening due to vibration or impact.

[0060] 6. Template disassembly and reset process When the template needs to be disassembled, manually rotate to release the locking structure: By manual or external force, rotate the pin rod 420 in the direction of the spiral engaging groove 422 of the convex locking disc 421 to vertically separate the template base 100 and the injection molding machine template 200. Then, horizontally pull the injection molding machine template 200 to disengage the surface of the rubber buckle wheel 331 and the buckle groove 321. The torsion spring 430 rotates under the action of the elastic force to release the locked state.

[0061] By applying an external force, the guide rack 330 is withdrawn from the inside of the main gear disk 320, and the spiral spring 340 restores the main gear disk 320 to its initial position under the action of elastic force.

[0062] After the guide rack 330 is completely disengaged from the main gear disk 320, the connection between the template base 100 and the injection molding machine template 200 is completely released, and the disassembly operation of the template is completed.
