Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, specifically to an injection molding machine template that facilitates accurate docking. Background Technology

[0002] In the field of injection molding, the injection molding machine template is a crucial component, and its mold closing accuracy and assembly stability directly affect the molding quality of the injection molded product. In current injection molding technology, the assembly and mold closing of the injection molding machine template often relies on manual alignment and positioning. This method has the following defects and shortcomings:

[0003] In the current injection molding machine mold platen assembly process, direct guide post positioning or simple snap-fit ​​structures are typically used, lacking automatic guiding and locking functions. During mold platen assembly, misalignment or displacement can easily occur due to assembly position errors or external force interference, affecting mold closing accuracy and reducing the consistency and molding quality of injection molded products.

[0004] During injection molding, the mold platen needs to withstand a high-temperature and high-pressure working environment, and the opening and closing of the mold during injection molding will generate periodic vibrations and impacts. The splicing structure of existing injection molding machine mold plates mostly adopts screw or clip fixing methods, which lacks self-locking function. They are prone to loosening or deformation of the splice parts due to vibration or load changes, which affects the injection accuracy and molding quality.

[0005] In the process of assembling and disassembling existing injection molding machine templates, manual assistance is usually required for positioning and fixing. The positioning position needs to be adjusted frequently during the operation, which is cumbersome, has poor positioning accuracy, affects injection molding production efficiency, and increases labor intensity.

[0006] Existing injection molding machine templates often lack limiting and locking devices during the splicing process, which can easily lead to loosening or separation of the spliced ​​structure due to operational errors or mechanical vibrations. This results in poor structural stability and operational safety hazards, making it difficult to meet the stability and safety requirements of modern injection molding production processes. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] The present invention provides an injection molding machine template for easy and accurate docking, comprising a template base, an injection molding machine template, a splicing assembly, a snap fastener, and a locking disc and a telescopic rod fixedly installed on the surfaces of the template base and the injection molding machine template;

[0009] One end of the telescopic rod is fixedly connected to the end of the splicing assembly. There are two sets of splicing assemblies, which are respectively fixed to the opposite surfaces of the template seat and the injection molding machine template. The fasteners correspond one-to-one with the locking discs and are arranged opposite to each other.

[0010] The splicing assembly includes a sliding sleeve seat, a main gear plate, a guide rack, and a helical spring located inside the main gear plate. The axis of the helical spring is fixed to the inner side of the sliding sleeve seat. The surface of the guide rack is provided with a pulley for sliding contact with the inner wall of the sliding sleeve seat. One side of the guide rack is provided with a straight tooth surface that meshes with the surface of the main gear plate, and the straight tooth surface is arranged obliquely. One end of the guide rack is rotatably mounted with a rubber buckle wheel. The surface of the main gear plate is provided with a buckle groove that matches the rubber buckle wheel.

[0011] Preferably, the snap fastener includes a fixed base and a pin rotatably mounted inside the fixed base. A torsion spring is sleeved on the surface of the pin, and the other end of the torsion spring is fixedly connected to the inner side of the fixed base. One end of the pin is provided with a convex locking plate, and the surface of the convex locking plate is provided with a mating groove. The surface of the locking plate is provided with a convex fastening piece, and the shape and size of the convex fastening piece are adapted to the mating groove.

[0012] Preferably, the convex locking disc is conical, one side of the convex buckle is inclined, and the engaging groove is spirally arranged to guide the deflection movement of the shaft pin when the convex locking disc is inserted into the surface of the buckle disc.

[0013] Preferably, the convex locking plate and the locking plate form a self-locking structure through a torsion spring. During the mold closing process, the torsion spring's elastic reset action enables passive deflection and automatic reset between the convex locking plate and the locking plate.

[0014] Preferably, the helical spring and the main gear disk are fixedly connected by a snap-fit ​​groove structure. During the splicing process, the helical spring forms energy storage through elastic compression. After disassembly, the main gear disk is reset and rotated by the helical spring.

[0015] Preferably, the rubber buckle wheel is a component made of rubber. When the two splicing components are in the splicing state, the outer periphery of the rubber buckle wheel is in interference fit with the inner side of the buckle groove.

[0016] Preferably, the guide rack and the main gear disk are connected by a toothed meshing structure, and the surface pulley of the guide rack slides smoothly along the inner side of the sliding sleeve seat.

[0017] Preferably, the helical spring is planar helical and is in a natural state during non-splicing processes, allowing the guide rack to extend out of the sliding sleeve seat to reach its maximum elongation. During splicing, the helical spring is in a compressed and stored state.

[0018] Preferably, the telescopic rod is an elastic piston rod structure, used to provide elastic tension when the template seat and the injection molding machine template are connected, and to maintain the frictional contact between the shaft pin and the inner side of the convex fastener.

[0019] At the start of assembly, the helical spring remains in a naturally stretched state, and the guide rack is extended from the sliding sleeve seat. Through manual handling or hoisting equipment, the two templates are gradually brought closer together. In the two splicing components, the outer tooth surface of the guide rack inside one sliding sleeve seat meshes with the toothed structure on the main gear disc inside the other sliding sleeve seat, forming a guiding effect.

[0020] During the splicing process, the guide rack slides along the guide groove of the sliding sleeve seat and drives the main gear plate to rotate until the buckle groove on the surface of the main gear plate contacts the rubber buckle wheel, forming a self-locking state, ensuring that the two splicing components are in a locked state, and that the locking plate and the pressing fastener are in relative positions.

[0021] During the locking process, the surface of the vertical injection molding machine template is pressed, causing the template seat to close with the injection molding machine template. The telescopic rod retracts elastically, and the fastener moves closer to the locking disc. The surface engagement groove of the convex locking disc passively contacts the convex fastening piece on the locking disc, and the spiral structure of the engagement groove causes the convex locking disc to passively deflect. The torsion spring stores energy and twists, and the surface engagement groove of the convex locking disc meshes with the convex fastening piece on the locking disc, allowing the convex locking disc to enter the interior of the locking disc.

[0022] In the locked state, the docking distance and position between the template holder and the injection molding machine template are precisely locked to prevent displacement or loosening during subsequent injection molding.

[0023] During the assembly process, the guide rack forms a guiding engagement with the surface of the sliding sleeve seat via pulleys. As the main gear plate rotates, the guide rack slides smoothly along the surface of the sliding sleeve seat. The pulleys on the surface of the guide rack form a limiting engagement inside the sliding sleeve seat, preventing lateral displacement or misalignment of the guide rack during assembly and ensuring the accuracy and stability of the template connection.

[0024] After assembly, the fasteners maintain a stable locking state through the meshing structure between the convex locking disc and the locking disc. Because the engagement groove has a spiral structure, when subjected to external force, the convex locking disc and the locking disc can convert the force into a deflection force on the shaft pin, preventing the convex locking disc from loosening due to vibration or impact.

[0025] When it is necessary to disassemble the mold plate, external force is applied to rotate the pin along the spiral groove direction of the convex locking disc, releasing the locking state. External force is then applied to disengage the guide rack from the inside of the main gear plate, and the helical spring returns the main gear plate to its initial position under the action of elasticity. After the guide rack is completely disengaged from the main gear plate, the connection between the mold plate holder and the injection molding machine mold plate is completely released, completing the mold plate disassembly operation.

[0026] This invention, through the linkage structure design between the splicing components and the clamping parts, can achieve automatic positioning and locking during the splicing and disassembly of the injection molding machine template, thereby improving the splicing accuracy and stability of the injection molding machine template, effectively preventing the template from shifting or loosening during the injection molding process, and ensuring the molding accuracy of the injection molded workpiece.

[0027] The beneficial effects achieved by this invention are as follows:

[0028] 1. In this invention, by setting up a splicing assembly including a main gear plate, a guide rack and a helical spring, the tooth meshing transmission structure between the guide rack and the injection molding machine template can realize automatic guidance and self-locking during the splicing process, preventing misalignment or offset during the splicing process, and significantly improving the accuracy and stability of template splicing.

[0029] 2. In this invention, after the splicing is completed, the convex locking plate and the locking plate form a locking structure through the joint groove and the convex fastening piece, which can enhance the seismic and impact resistance of the splicing structure when subjected to vibration or load changes, prevent the splicing from loosening, and improve the safety and reliability of equipment operation.

[0030] 3. In this invention, the cooperation between the helical spring, pulley and guide rack enables the template to be quickly aligned during splicing and smoothly reset during disassembly by sliding between the main gear plate and the guide rack, thereby reducing the difficulty of manual operation and improving the convenience of splicing and disassembly.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0044] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0045] The following is in conjunction with the appendix Figures 1 to 8 The present invention describes an injection molding machine template that facilitates accurate docking, according to some embodiments thereof.

[0046] Example 1

[0047] This invention relates to an injection molding machine template that facilitates accurate docking, specifically including a template base 100, an injection molding machine template 200, a splicing assembly 300, a locking plate 110, a telescopic rod 210, and a pressure fastener 400. The template base 100 and the injection molding machine template 200 are quickly docked and locked together via the splicing assembly 300 and the pressure fastener 400.

[0048] The splicing assembly 300 includes a sliding sleeve seat 310, a main gear plate 320, a guide rack 330, and a helical spring 340 disposed inside the main gear plate 320. The sliding sleeve seat 310 is mounted on the opposing surfaces of the template seat 100 and the injection molding machine template 200. The guide rack 330 forms a sliding guide connection with the sliding sleeve seat 310 through a pulley 332. The straight tooth surface of the guide rack 330 meshes with the tooth structure on the main gear plate 320 to form a transmission structure. The main gear plate 320 has a locking groove 321 on its surface, and the locking groove 321 cooperates with the rubber locking 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 plate 320 through a snap-fit ​​groove structure, forming elastic compression energy storage during the splicing process, and realizing the reset of the main gear plate 320 through elastic rebound during disassembly.

[0049] Locking disc 110 and pressing fastener 400: The locking disc 110 and pressing fastener 400 are respectively mounted on the opposing surfaces of the template base 100 and the injection molding machine template 200. The locking disc 110 has a protruding fastener piece 111 on its surface, which mates with the engaging groove 422 of the protruding locking disc 421 on the pressing fastener 400. The pressing fastener 400 includes a fixed base 410, a pivot pin 420, and a torsion spring 430. The protruding locking disc 421 is rotatably connected to the fixed base 410 via the pivot pin 420, and the torsion spring 430 provides locking and resetting functions.

[0050] Example 2: Automated control of assembly and disassembly

[0051] This embodiment provides an automated control system to improve the accuracy and efficiency of template docking and disassembly. In this embodiment, an automated control device is introduced into the splicing process of the template base 100 and the injection molding machine template 200, improving the overall stability and reliability of the splicing.

[0052] 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 by an automated control device. The two templates are parallelly connected via an electric push rod or hydraulic drive system, and a laser positioning system is used to precisely correct the assembly position of the templates. Based on the detected template position, the system fine-tunes the position of the templates by controlling the drive device to ensure precise alignment of the assembly component 300.

[0053] 2. Automatic locking of splicing component 300: The automated system controls the connection process of splicing component 300 through a real-time feedback mechanism. The engagement of guide rack 330 and main gear disk 320 no longer relies on manual adjustment. The system determines whether guide rack 330 and main gear disk 320 are fully aligned based on sensor signals, ensuring that each splice reaches the optimal position. During engagement, the rubber-coated wheel 331 and the locking groove 321 cooperate perfectly to achieve self-locking.

[0054] 3. Automatic locking of locking disc 110 and pressing fastener 400: When the template base 100 begins to mate with the injection molding machine template 200, the automatic control device precisely mates the locking disc 110 and the pressing fastener 400. The pressing fastener 400 is controlled to move closer to the locking disc 110 via an electric valve and pneumatic device, and the convex locking disc 421 and the mating groove 422 form a precise fit, completing the locking.

[0055] 4. Limitation and stability maintenance of guide rack 330: Under the control of the automated system, the pulley 332 always slides along the inner wall of the sliding sleeve seat 310 during the sliding process of guide rack 330, ensuring the stable operation of guide rack 330. This design further improves the smoothness and accuracy of the splicing process.

[0056] Furthermore, this embodiment optimizes the guiding system during the splicing process and adds a protective design to prevent loosening, thereby improving the stability and safety of the template during the operation of the injection molding machine.

[0057] In this embodiment, a laser docking system is used when the template holder 100 and the injection molding machine template 200 are initially docked. This system can detect the real-time position and error of the template and automatically adjust the distance between the template holder 100 and the injection molding machine template 200 through a fine-tuning drive device to ensure that the two templates are docked in parallel.

[0058] To prevent the spliced ​​template from loosening under high-pressure working conditions, this embodiment designs a dual locking mechanism. In addition to the traditional helical spring 340, a mechanical locking device is added between the splicing component 300 and the locking plate 110. This device utilizes a sliding locking pin and locking groove structure to ensure that the spliced ​​template does not shift or loosen.

[0059] This embodiment also improves the template disassembly process. During template disassembly, the release of the helical spring 340 and torsion spring 430 is controlled by an electric motor, making the disassembly process faster and more stable. Through the operation of the automated device, the template holder 100 and the injection molding machine template 200 can be accurately separated, avoiding possible errors during manual disassembly.

[0060] To improve the stability of the template, this embodiment incorporates a shock-absorbing design. A wear-resistant elastic material is used to buffer the connection between the locking disc 110 and the pressure fastener 400, reducing the impact of external vibrations on the locking structure and further enhancing the stability of the template after assembly.

[0061] Example 3: Modular Design and Scalability

[0062] This embodiment provides a modular injection molding machine template structure, which allows users to customize and expand the template according to different needs.

[0063] 1. Modular splicing component 300: Unlike traditional fixed splicing components, this embodiment uses a modular splicing component 300, allowing users to select different specifications and types of main gear discs 320 and guide racks 330 according to specific needs. This design makes the injection molding machine template more adaptable and suitable for different types of injection molding machines.

[0064] 2. Compatibility between locking plate 110 and pressing fastener 400: This embodiment designs various specifications and shapes of accessories between locking plate 110 and pressing fastener 400, allowing for flexible combination of injection molding machine templates of different specifications. Users only need to select the corresponding accessories according to the template requirements, which greatly facilitates template customization and replacement.

[0065] This invention, through multiple embodiments, successfully achieves rapid assembly, automatic positioning, and locking of injection molding machine templates that facilitate accurate docking, while providing higher stability and reliability. The innovative technologies introduced in different embodiments, such as automated control, intelligent auxiliary systems, and modular design, greatly enhance the application scope and practicality of this invention. Through these designs, this invention can meet the needs of different injection molding machine equipment and ensure the stability and safety of the injection molding machine templates under high-load operating environments.

[0066] Working principle and usage process of this invention:

[0067] This invention relates to an injection molding machine template 200 that facilitates accurate alignment. By incorporating a splicing assembly 300, a locking disc 110, a pressure fastener 400, and a telescopic rod 210, it achieves rapid alignment, automatic positioning, and locking of the injection molding machine template 200, improving the mold closing accuracy and stability of the template and preventing misalignment or loosening. Its complete working principle is as follows:

[0068] 1. Initial positioning and assembly process of the template

[0069] Before splicing, the template base 100 and the injection molding machine template 200 are arranged parallel to each other, and the 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.

[0070] At the start of the assembly, the helical spring 340 remains in a naturally stretched state, and the guide rack 330 is in an extended state on the surface of the sliding sleeve seat 310.

[0071] By handling the two templates manually or with hoisting equipment, the two relatively moving splicing components 300 are brought closer together. In one of the sliding sleeve seats 310, the outer tooth surface of the guide rack 330 inside the slide sleeve seat 310 meshes with the tooth structure on the main gear disk 320 inside the other slide sleeve seat 310, thus forming a guiding effect.

[0072] 2. Interlocking and automatic locking of splicing component 300

[0073] When the guide rack 330 and the main gear disk 320 form an initial meshing state, the two splicing components 300 begin to connect gradually:

[0074] 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 base 310 and drives the main gear plate 320 to rotate;

[0075] Until the groove 321 on the surface of the main gear plate 320 comes into contact with the rubber fastener 331, forming a self-locking state, ensuring that the two splicing components 300 are in a locked state, and that the locking plate 110 and the pressing fastener 400 are in relative positions.

[0076] 3. Automatic locking of locking disc 110 and fastener 400

[0077] During the docking process between the template base 100 and the injection molding machine template 200, the locking plate 110 and the pressing fastener 400 are gradually docked:

[0078] Pressing the surface of the vertical injection molding machine template 200 causes the template seat 100 to close with the injection molding machine template 200, the telescopic rod 210 to retract elastically, and the fastener 400 to move closer to the locking plate 110.

[0079] The surface engagement groove 422 of the convex locking disc 421 passively contacts the convex fastening piece 111 on the locking disc 110, and the convex locking disc 421 is passively deflected by the spiral structure of the engagement groove 422. The torsion spring 430 stores energy and twists, and the surface engagement groove 422 of the convex locking disc 421 engages with the convex fastening piece 111 on the locking disc 110, so that the convex locking disc 421 can enter the interior of the locking disc 110.

[0080] After the locking disc 110 enters, the pin 420 is guided to deflect and lock by means of the restoring force of the torsion spring 430.

[0081] In the locked state, the docking distance and position between the template holder 100 and the injection molding machine template 200 are precisely locked to prevent displacement or loosening during subsequent injection molding.

[0082] 4. Limitation and stability maintenance of guide rack 330

[0083] During the assembly process, the guide rack 330 forms a guiding engagement with the surface of the sliding sleeve seat 310 through the pulley 332:

[0084] During the rotation of the main gear disk 320, the guide rack 330 slides smoothly along the surface of the sliding sleeve seat 310.

[0085] The pulley 332 on the surface of the guide rack 330 forms a limiting fit inside the sliding sleeve seat 310 to prevent the guide rack 330 from shifting or misaligning during the splicing process, thus ensuring the accuracy and stability of the template docking.

[0086] 5. Locking state retention and anti-loosening effect

[0087] After the assembly is completed, the snap fastener 400 maintains a stable locking state through the meshing structure between the convex locking disc 421 and the locking disc 110:

[0088] Because the engagement groove 422 has a spiral structure, when the convex locking disc 421 and the locking disc 110 are subjected to external force, the external force can be converted into the deflection force of the shaft pin 420 through the spiral structure, preventing the convex locking disc 421 from loosening due to vibration or impact.

[0089] 6. Template disassembly and repositioning process

[0090] When it is necessary to disassemble the template, manually rotate the unlocking mechanism:

[0091] By manually or through external force, the convex locking disc 421 rotates the shaft pin 420 along the spiral joint groove 422 direction, vertically separating the template seat 100 from the injection molding machine template 200. Then, the injection molding machine template 200 is pulled laterally to disengage the rubber buckle wheel 331 from the surface of the buckle groove 321. The torsion spring 430 rotates under the action of elasticity, releasing the locking state.

[0092] The guide rack 330 is disengaged from the inside of the main gear plate 320 by external force, and the helical spring 340 restores the main gear plate 320 to its initial position under the action of elastic force.

[0093] After the guide rack 330 is completely disengaged from the main gear plate 320, the connection between the template seat 100 and the injection molding machine template 200 is completely released, completing the template disassembly operation.

[0094] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
