Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and in particular to a high-precision two-platen injection molding machine with mold adjustment function. Background Technology

[0002] Injection molding machines are key equipment for molding thermoplastics and some thermosetting materials. Their working principle involves the clamping device closing the mold, the injection unit melting the plastic and injecting the molten plastic into the mold cavity, and then, after pressure holding and cooling to solidify, the ejection mechanism on the injection unit ejects the finished product from the mold cavity, completing one injection molding process. Two-platen injection molding machines are favored by the market for their compact structure, high rigidity, large mold opening force and stroke, and precise control of clamping force. To accommodate different mold thicknesses, the equipment is equipped with a mold adjustment mechanism to automatically adjust the distance between the moving and fixed platen sections.

[0003] Chinese patent CN202323627920.X discloses a dual-electric-drive two-platen injection molding machine, belonging to the field of injection molds. The device includes a base, a fixed mold, and a movable mold. A direct-drive motor is fixedly connected to the left and right sides of the fixed mold, and lead screws are fixedly connected to the output ends of both sets of direct-drive motors. Internal threaded sleeves are fixedly connected to both sides of the movable mold, and the two sets of lead screws are threadedly connected to the two sets of internal threaded sleeves. The two sets of direct-drive motors synchronously drive the two sets of lead screws to rotate, thereby driving the internal threaded sleeves and the movable mold to move rapidly. Simultaneously, two sets of sliders at the bottom of the movable mold slide rapidly on linear guide rails. The operation of the dual direct-drive motors in conjunction with the dual linear guide rails results in a fast response speed in the two-platen mold-locking transmission. Furthermore, the independent movement of the mold by the dual electric drives allows for both synchronous and delayed perfect coordination of actions such as ejector pin, brake, and high-pressure cylinder reset, effectively achieving high machine efficiency and high precision requirements.

[0004] Chinese patent CN202411794300.1 discloses an automatic mold adjustment method, device, equipment, and storage medium for a two-platen injection molding machine. The two-platen injection molding machine includes a fixed platen, a moving platen, guide pillars, a brake assembly, a locking cylinder, an electronic ruler for the piston position of the locking cylinder, an electronic ruler for the position of the moving platen, and a mold shifting drive assembly. Multiple guide pillars are included, each equipped with a brake assembly and a locking cylinder. Both the guide pillars and the mold shifting drive assembly are fixedly connected to the fixed platen. The mold shifting drive assembly is connected to the moving platen via a telescopic rod, which extends or retracts, thereby moving the moving platen along the guide pillars. The locking cylinder is fixed to the moving platen, and the brake assembly is located on the outer end face of the piston of the locking cylinder. The guide pillars have guide pillar ring teeth, and the brake assembly has brake concave teeth. When braking is required, the piston of the locking cylinder drives the brake assembly to the braking position, and then the brake assembly brakes, causing the guide pillar ring teeth to engage with the brake concave teeth.

[0005] However, existing two-platen injection molding machines are limited by the structure and layout of the drive mechanism, making it difficult to meet the requirements of high-speed, long-stroke mold moving operations. High-speed operation places higher demands on the stability and precision of the equipment and affects the service life of components. For the lead screw drive mechanism, especially under high mold opening and closing speeds, there are limitations on the length of the lead screw. Excessive length can easily lead to vibration, and the lengthened custom lead screw is difficult to manufacture and has high costs. Therefore, the mold closing space is difficult to adjust. Existing two-platen injection molding machines are difficult to adapt to high-speed, long-stroke mold opening and closing applications, and their mold adjustment efficiency is low, with long downtime for mold adjustment, affecting the production capacity of the equipment. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-precision two-platen injection molding machine with mold adjustment function.

A limiting platform is erected on the frame on the left side of the sliding plane. The left side of the sliding foot, perpendicular to the sliding direction, contacts the limiting platform, and the right side is engaged with the main body of the mold adjustment slide in a stepped manner.

[0016] As an improvement, the sliding feet are evenly distributed on the left and right sides, such as a total of 6 sets.

[0017] As an improvement, the lead screw drive mechanism includes a drive unit mounted on the mold adjustment slide, a lead screw that is horizontally arranged and driven to rotate by the drive unit, and a nut that cooperates with the lead screw and is connected to the moving template. The mold adjustment slide is provided with a slide rail for slidingly assembling the nut, and the slide rail is arranged on the effective support surface of the sliding plane.

[0018] As an improvement, the drive unit adopts a motor, and the two ends of the lead screw are rotatably mounted on the mold adjustment slide, with the tail end connected to the rotary drive end of the drive unit.

[0019] As an improvement, the top of the sliding plane is a steel strip A, the bottom of the sliding foot is a copper block A, and the copper block A slides in contact with the steel strip A; the side of the limiting platform is provided with a steel strip B, the left side of the sliding foot is a copper block B, and the copper block B slides in contact with the steel strip B.

[0020] As an improvement, the vibration damping mechanism includes a support base, which is connected to the nut of the lead screw drive mechanism and slidably mounted on the mold adjustment slide. The support base has an arc-shaped groove that matches the shape of the lead screw in the lead screw drive mechanism, and the lead screw is placed in the arc-shaped groove.

[0021] As an improvement, the support base is slidably mounted on the slide rail.

[0022] As an improvement, the vibration damping mechanism also includes a wear-resistant pad, which is configured to match the shape of the arc-shaped groove and installed inside the arc-shaped groove, and the wear-resistant pad is in contact with the lead screw.

[0023] As an improvement, the wear-resistant pad is made of plastic or graphite.

[0024] As an improvement, the arc-shaped groove is recessed with an installation groove, and the wear-resistant pad is fitted into the installation groove.

[0025] As an improvement, the mold locking mechanism includes a left and a right chuck mounted on the mold adjusting slide and arranged to slide relative to each other, a locking rod mounted on the frame, and fasteners that drive the left and right chucks to engage and engage or disengage the locking rod in a conformal manner.

[0026] The length direction of the locking rod is consistent with the sliding direction of the mold adjustment slide, and the mold adjustment slide has a space inside for the locking rod to extend into.

[0027] As an improvement, the outer circumferential surface of the locking rod is provided with toothed structures spaced apart along the axial direction, and the locking working surfaces of the left and right pawls that cooperate with the locking rod are also provided with toothed structures.

[0028] The beneficial effects of this invention are as follows: (1) This invention achieves high-speed operation by adopting a lead screw drive method and a reasonable layout design of its configuration position, thereby configuring high driving force.

(2) This invention sets up a mold adjustment structure to match different molds for mold adjustment, and combines the screw in the screw drive structure to make a long stroke structure, and increases the mold closing space by adjusting the mold, thereby realizing the configuration to meet the mold moving requirements of longer stroke, while taking into account the high precision and low cost of the equipment. By adopting a multi-level mold adjustment design, combining coarse adjustment and fine adjustment, the efficiency and convenience of mold adjustment are effectively improved, the downtime of mold adjustment is shortened, and the production capacity of the equipment is increased. With the mold locking design, the stability and accuracy of the equipment operation are further guaranteed, adapting to high-speed working conditions. Moreover, the claw-type mold locking structure is convenient and time-saving to operate, and can achieve rapid locking and save downtime.

[0029] (3) In the first-stage mold adjustment structure of the present invention, the sliding fit structure adopts a planar sliding fit structure of a wide sliding plane and a sliding foot, combined with the material fit of steel strip and copper block. It not only has low friction and strong wear resistance, but also can use the wide bearing surface to effectively support the second-stage mold adjustment drive structure, improve the stability and accuracy of equipment operation, save the cost of component wear, maintenance and replacement, and take into account both economy and practicality. Furthermore, a left and right limit structure is set to stabilize the slide in the left and right directions, ensuring that it effectively maintains position accuracy when it moves.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] Example like Figure 1As shown, a high-precision two-platen injection molding machine with mold adjustment function includes a frame 1, on which a moving platen 4 and a fixed platen 7 are arranged opposite to each other. The moving platen 4 is slidably set relative to the fixed platen 7 by at least one level of mold adjustment drive module I. The mold adjustment drive module I includes a screw drive mechanism 5 for driving mold adjustment and mold opening and closing actions.

[0035] As an improvement, the mold adjustment drive module I further includes a mold adjustment slide 2 slidably disposed on the frame 1 and a mold adjustment drive component 3 for driving the mold adjustment slide 2 to slide. The moving template 4 is slidably disposed on the mold adjustment slide 2 to perform multi-level mold adjustment operations.

[0036] It is worth noting that the multi-stage mold adjustment method not only takes into account the high efficiency and high precision of the mold adjustment operation, but also considers the economy and durability of the lead screw for the drive design of the lead screw and nut structure, while also needing to adapt to high-speed mold opening and closing operation conditions. In this embodiment, a mold adjustment mechanism is used to increase the mold closing space, which is ingenious, practical and low cost.

[0037] In this embodiment, when performing mold adjustment, a primary mold adjustment structure including the mold adjustment slide 2 and the mold adjustment drive 3 can be used for preliminary adjustment, and then a secondary mold adjustment structure including the moving template 4 and the lead screw drive mechanism 5 can be used for fine adjustment, thereby taking into account both the high efficiency and high precision of the mold adjustment operation.

[0038] As an improvement, the mold adjustment drive 3 is connected between the frame 1 and the mold adjustment slide 2, and it adopts a hydraulic cylinder, air cylinder or screw nut structure.

[0039] In some embodiments, such as Figure 9 As shown, the mold adjustment drive component 3 adopts a hydraulic cylinder structure and has two sets symmetrically distributed on the left and right sides of the mold adjustment slide 2. The main body of the hydraulic cylinder is installed on the mold adjustment slide 2, and the extension and retraction drive end of the hydraulic cylinder is connected to the frame 1 through the connecting seat 13 installed on the frame 1.

[0040] As an improvement, the moving template 4 is slidably connected to the mold adjustment slide block 2 through a slide rail slider pair structure.

[0041] As an improvement, such as Figure 2 As shown, the mold adjustment drive module I also includes a vibration damping mechanism 8. The lead screw drive mechanism 5 is installed on the mold adjustment slide 2 and connected to the bottom of the moving template 4. The vibration damping mechanism 8 is connected to the nut part of the lead screw drive mechanism 5 and slides synchronously with it to provide dynamic support for the lead screw part when the lead screw drive mechanism 5 is working.

[0042] In this embodiment, the lead screw drive mechanism 5 adopts a motor drive combined with a lead screw and nut transmission structure. The lead screw 52 can be a long stroke structure and is equipped with a vibration damping mechanism 8 to prevent vibration that may be caused by the excessive length of the lead screw. The vibration damping mechanism 8 moves synchronously with the nut 53 to achieve dynamic support, resulting in good support and vibration damping effects.

[0043] In some embodiments, a set of lead screw drive mechanisms 5 are provided and arranged at the bottom center position of the moving template 4.

[0044] In other embodiments, the lead screw drive mechanism 5 is provided in two sets and symmetrically arranged on both sides of the bottom of the moving template 4.

[0045] This embodiment designs the configuration position of the lead screw drive mechanism 5 by reasonably arranging it and setting it on the bottom surface of the moving template 4. The position space is sufficient and the size is not limited. A high-power motor can be used to achieve rapid mold movement with high speed and high driving force.

[0046] As an improvement, such as Figure 1 As shown, the mold adjustment drive module I also includes a mold locking mechanism 6, which locks the mold adjustment slide 2 after the mold adjustment is completed.

[0047] Since the moving template 4 generates a reaction force on the mold adjustment slide 2 during the mold opening and closing action, the mold adjustment slide 2 needs to be locked after the mold adjustment is completed to ensure the stability of the mold opening and closing action, improve the fitting accuracy, and better adapt to high-speed mold opening and closing conditions.

[0048] As an improvement, such as Figure 3 As shown, the top of the frame 1 is provided with a sliding plane 11, and the bottom of the mold adjustment slide 2 is provided with a plurality of sliding feet 21 that slide in cooperation with the sliding plane 11. A limiting platform 12 is erected on the frame 1 to the left of the sliding plane 11. The left side of the sliding foot 21 perpendicular to the sliding direction contacts the limiting platform 12, and the right side engages with the main body of the mold adjustment slide 2 in a stepped manner to limit the mold adjustment slide 2 in the left and right directions.

[0049] As an improvement, the sliding feet are evenly distributed on the left and right sides, such as a total of 6 sets.

[0050] As an improvement, such as Figure 4 As shown, the lead screw drive mechanism 5 adopts a lead screw and nut transmission structure, which includes a drive unit 51 mounted on the mold adjustment slide 2, a lead screw 52 horizontally arranged and driven to rotate by the drive unit 51, and a nut 53 that cooperates with the lead screw 52 and is connected to the moving template 4. The mold adjustment slide 2 is provided with a slide rail 22 for slidingly assembling the nut 53, and the slide rail 22 is arranged on the effective support surface of the sliding plane 11, such as... Figure 5 As shown.

[0051] Since deformation is inevitable during equipment operation, which leads to equipment wear, the sliding structure in this embodiment has an unrestricted steel belt support surface width and load-bearing capacity, so that its effective support point is as close as possible to the slide rail 22 of the screw drive mechanism 5, thereby taking into account its effective support, improving the stability and accuracy of equipment operation, and saving on component wear, maintenance and replacement costs.

[0052] As an improvement, the drive unit 51 is a motor, and the two ends of the lead screw 52 are rotatably mounted on the mold adjustment slide 2, and the tail end is connected to the rotation drive end of the drive unit 51.

[0053] As an improvement, such as Figure 3 , 5 As shown, the top of the sliding plane 11 is a steel strip A111, and the bottom of the sliding foot 21 is a copper block A211 with a graphite rod embedded in the middle. The copper block A211 and the steel strip A111 slide in contact. The side of the limiting platform 12 is provided with a steel strip B121, and the left side of the sliding foot 21 is a copper block B212 with a graphite rod embedded in the middle. The copper block B212 and the steel strip B121 slide in contact.

[0054] Among them, the friction between the copper block and the steel strip is small, and the wear resistance is excellent. This embodiment adopts a sliding structure with the steel strip and copper block sliding feet cooperating and a left and right locking and limiting structure, which is low in cost and highly practical, with low frictional resistance, high precision, and a wide support surface of the steel strip and no limitation on the load-bearing weight.

[0055] In this embodiment, the main body of the mold adjustment slide 2 on one side is stepped and engages with the sliding foot 21, while the other side is engaged with the steel strip B121 through the lateral copper block B212, thereby achieving stable positioning of the entire mold adjustment slide 2 in the left and right directions and ensuring that it maintains positional accuracy effectively during operation.

[0056] This embodiment adopts a sliding structure with steel strip and copper block sliding foot and a left and right locking limit structure, which is low in cost, highly practical, has low frictional resistance and high precision.

[0057] As an improvement, such as Figure 6-8 As shown, the vibration damping mechanism 8 includes a support base 81, which is connected to the nut 53 of the lead screw drive mechanism 5 and slidably mounted on the mold adjustment slide 2. The support base 81 has an arc-shaped groove 80 that matches the shape of the lead screw 52 in the lead screw drive mechanism 5, and the lead screw 52 is placed in the arc-shaped groove 80.

[0058] As an improvement, the support base 81 is slidably mounted on the slide rail 22.

[0059] As an improvement, the vibration damping mechanism 8 also includes a wear-resistant pad 82, which is configured to match the shape of the arc-shaped groove 80 and installed in the arc-shaped groove 80. The wear-resistant pad 82 is in contact with the lead screw 52.

[0060] In this embodiment, the support contact surface between the vibration damping mechanism 8 and the lead screw 52 is designed to be wear-resistant, thereby improving operational stability and accuracy, and extending the service life of the equipment.

[0061] As an improvement, the wear-resistant pad 82 is made of plastic or graphite.

[0062] As an improvement, the arc-shaped groove 80 is recessed with an installation groove, and the wear-resistant pad 82 is fitted into the installation groove to improve installation stability and prevent displacement due to sliding friction, which would affect the function.

[0063] As an improvement, such as Figure 9 As shown, the mold locking mechanism 6 includes a left jaw 61 and a right jaw 62 mounted on the mold adjusting slide 2 and arranged to slide relative to each other, a locking rod 63 mounted on the frame 1 via a connecting seat 13 mounted on the frame 1, and a fastener 64 that drives the left and right jaws to engage and engage or disengage the locking rod 63 in a contoured manner.

[0064] The length direction of the locking rod 63 is consistent with the sliding direction of the mold adjustment slide 2, and the mold adjustment slide 2 has a space inside for the locking rod 63 to extend into.

[0065] This embodiment uses a claw locking structure to achieve rapid locking, which is convenient and quick to operate and saves downtime.

[0066] As an improvement, the outer circumferential surface of the locking rod 63 is provided with toothed structures spaced apart along the axial direction, and the locking working surfaces of the left pawl 61 and the right pawl 62 that cooperate with the locking rod 63 are also provided with toothed structures to prevent slippage and misalignment due to high-speed impact, and to ensure stability and accuracy.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
