Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a centering adjustment device and a top-side injection molding equipment. Background Technology

[0002] In the field of plastic product injection molding, injection molding equipment with top-side vertical injection is widely used. Its core operation is to achieve precise docking between the nozzle and the mold sprue sleeve along the top-side direction (from top to bottom). This operation directly determines whether the molten plastic can be stably injected into the mold cavity, which is the key to ensuring the product molding quality and production continuity.

[0003] In existing technologies, for injection molding equipment using a top-side vertical injection method, the alignment of the nozzle and the mold sprue bushing mainly relies on manual adjustment. Specifically, the nozzle and sprue bushing are aligned by adjusting the installation position of the injection unit in the X / Y direction, the advance distance of the injection stage, or the installation position of the mold, thereby ensuring the smooth progress of the injection molding process.

[0004] However, the alignment of the nozzle and the mold sprue bushing relies on tedious manual adjustment, which cannot achieve automatic and precise alignment during the mold closing process. This is not only time-consuming and labor-intensive, but may also require repeated adjustments due to factors such as thermal expansion and mechanical stress, which seriously restricts the improvement of production efficiency.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a centering adjustment device and a top-side injection molding equipment to achieve automatic adjustment of the nozzle position, realize automatic and precise centering during the mold closing process, and improve production efficiency.

[0023] The front and rear position electronic ruler works in conjunction with the front and rear translation mechanism to detect the movement position of the firing platform in the front and rear direction.

[0024] Preferably, the centering adjustment device further includes a jet shifting bracket;

[0025] The ejector bracket is used to connect the front and rear sliding members to the vertical guide rail, or to connect the vertical sliding member to the front and rear guide rail.

[0026] Preferably, the front and rear guide rails include a base block, multiple gaskets, and a wear-resistant block, wherein:

[0027] The base block is mounted on the mounting component via the gasket, and the wear-resistant block is fixed to the top surface of the base block to form a sliding groove that runs through the front and rear directions. The front and rear sliding components slide and engage with the sliding groove.

[0028] The height of the groove formed by the base block and the wear-resistant block can be adjusted by increasing or decreasing the number of the shims, thereby adjusting the fit clearance between the front and rear sliding parts and the groove.

[0029] A top-side injection molding machine includes a mold, an injection station, and the aforementioned centering adjustment device. The centering adjustment device is disposed between the mold and the injection station and is used to adjust the relative position of the injection station and the mold so that the nozzle of the injection station aligns with the gate of the mold.

[0034] The injection assembly is mounted on the support member. The injection assembly includes an injection head plate, an injection tail plate, and an injection cylinder. The injection head plate and the injection tail plate are arranged opposite to each other. The injection cylinder is connected between the injection head plate and the injection tail plate and is used to drive the injection screw to move axially to complete the injection action.

[0035] The beneficial effects of this utility model are:

[0036] In this invention, the vertical translation mechanism and the forward and backward translation mechanism can drive the injection table to move automatically in the vertical and forward and backward directions, thereby realizing the automatic adjustment of the nozzle position. This eliminates the need for manual adjustment of the injection unit or mold installation position, replacing manual operation and solving the problem of relying on cumbersome manual adjustment.

[0037] In addition, the vertical translation mechanism and the forward and backward translation mechanism can drive the injection stage during the mold closing process. Compared with manual adjustment, the mechanical drive adjustment method has more stable position control, which can automatically align the nozzle and the gate during the mold closing process, realizing automatic and precise alignment during the mold closing process.

[0038] When the nozzle or mold shifts position due to factors such as thermal expansion and mechanical stress, the vertical translation mechanism and the forward and backward translation mechanism can automatically compensate for the shift by driving the injection table to move. This eliminates the need for repeated manual adjustments, reducing the time spent on adjustments and improving production efficiency. Attached Figure Description

[0049] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0050] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0051] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0052] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0053] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0054] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0055] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0056] Please see Figures 1 to 3 This embodiment provides a centering adjustment device for adjusting the relative position of the injection station 100 and the mold 200, so that the nozzle of the injection station 100 aligns with the gate of the mold 200. The centering adjustment device includes a mounting component 1, a vertical translation mechanism 2, and a front-to-back translation mechanism 3. The mounting component 1 is used to connect with the fixed platen of the mold 200. The vertical translation mechanism 2 is mounted on the mounting component 1 and is used to drive the injection station 100 to move vertically to adjust the position of the nozzle in the vertical direction. The front-to-back translation mechanism 3 is mounted on the mounting component 1 and is used to drive the injection station 100 to move forward and backward to adjust the position of the nozzle in the forward and backward direction.

[0057] With this configuration, mounting component 1 is connected to the fixed platen of mold 200, creating a relatively fixed connection between the entire adjustment device and mold 200. Vertical translation mechanism 2 is mounted on mounting component 1 and drives injection stage 100 to move vertically, thereby adjusting the position of the nozzle in the vertical direction. Similarly, forward and backward translation mechanism 3 is mounted on mounting component 1 and drives injection stage 100 to move forward and backward, thereby adjusting the position of the nozzle in the forward and backward direction. Through the coordinated action of vertical translation mechanism 2 and forward and backward translation mechanism 3, the nozzle is successfully connected to the gate of mold 200.

[0058] Understandably, the vertical translation mechanism 2 and the front-to-back translation mechanism 3 can drive the injection table 100 to move automatically in the vertical and front-to-back directions, thereby realizing the automatic adjustment of the nozzle position. This eliminates the need for manual adjustment of the injection unit or the installation position of the mold 200, replacing manual operation and solving the problem of relying on cumbersome manual adjustment.

[0059] It is also understandable that the vertical translation mechanism 2 and the front and rear translation mechanism 3 can drive the injection stage 100 to move during the mold closing process. Moreover, the mechanical drive adjustment method is more stable in position control than manual adjustment, which can automatically align the nozzle and the gate during the mold closing process, thus achieving automatic and precise alignment during the mold closing process.

[0060] In addition, when the nozzle or mold 200 shifts position due to factors such as thermal expansion and mechanical stress, the vertical translation mechanism 2 and the front and rear translation mechanism 3 can automatically compensate for the offset by driving the injection table 100 to move. This eliminates the need for repeated manual adjustments, thereby reducing the time spent on adjustments and improving production efficiency.

[0061] Specifically, the front-to-back translation mechanism 3 includes a front-to-back guide assembly 31 and a front-to-back drive assembly 32. The front-to-back guide assembly 31 includes a front-to-back guide rail 311 arranged in the front-to-back direction and a front-to-back sliding member 312 that slides in cooperation with the front-to-back guide rail 311. The front-to-back drive assembly 32 is used to drive the front-to-back sliding member 312 to slide along the front-to-back guide rail 311. The front-to-back guide rail 311 and the front-to-back sliding member 312 in the front-to-back guide assembly 31 form a sliding cooperation, which can provide stable guiding constraints for the front-to-back movement of the injection station 100, reduce the offset or shaking during the movement, and ensure that the injection station 100 moves accurately in the preset front-to-back direction. This helps to improve the accuracy of the nozzle position adjustment in the front-to-back direction, and thus improves the accuracy of the nozzle docking with the mold 200 gate. This solves the problem that it is difficult to achieve precise alignment by manual adjustment in the prior art.

[0062] Similarly, the vertical translation mechanism 2 includes a vertical guide assembly 21 and a vertical drive assembly 22. The vertical guide assembly 21 includes a vertical guide rail 211 arranged in the vertical direction and a vertical sliding member 212 that slides in cooperation with the vertical guide rail 211. The vertical drive assembly 22 is used to drive the vertical sliding member 212 to slide along the vertical guide rail 211. The sliding cooperation formed between the vertical guide rail 211 and the vertical sliding member 212 in the vertical guide assembly 21 provides a clear directional constraint for the vertical movement of the injection stage 100, reduces possible swaying or misalignment during movement, and ensures that the injection stage 100 moves stably along the preset vertical direction. This helps to improve the accuracy of the nozzle's vertical position adjustment, thereby ensuring the vertical docking accuracy between the nozzle and the mold 200 gate, and correspondingly solves the problem that manual adjustment is difficult to achieve precise alignment in the prior art.

[0063] Different injection molding machines have different structural layouts and mold 200 installation spaces. Some machines may have more space reserved in the front-to-back direction, while others have stricter space constraints in the vertical direction. Therefore, to improve the applicability of the centering adjustment device, the front and rear guide rails 311 are set on the mounting part 1, the front and rear sliding parts 312 are connected to the vertical guide rail 211, and the vertical sliding parts 212 are connected to the injection stage 100; or, the vertical guide rail 211 is set on the mounting part 1, the vertical sliding parts 212 are connected to the front and rear guide rails 311, and the front and rear sliding parts 312 are connected to the injection stage 100.

[0064] With this configuration, the installation relationship between the front and rear guide rails 311 and the vertical guide rail 211 can be flexibly selected, allowing the device to adjust its structural layout according to the actual space conditions of the equipment. This avoids the inability of a single fixed installation method to adapt to the space limitations of specific equipment, thereby expanding the device's adaptability to injection molding equipment of different specifications and structures.

[0065] In this embodiment, the installation method corresponding to the front and rear guide rails 311 being set on the mounting component 1 is used as an example. Specifically, the mounting component 1 is fixedly connected to the fixed template of the mold 200, serving as the basic load-bearing structure of the entire centering adjustment device. The front and rear guide rails 311 are fixedly installed on the mounting component 1 along the front-rear direction (i.e., the direction in which the injection stage 100 approaches or moves away from the mold 200). The front and rear sliding components 312 form a sliding fit with the front and rear guide rails 311, allowing them to slide stably along the extension direction of the front and rear guide rails 311. The front and rear drive assembly 32 is connected to the front and rear sliding components 312 and is used to drive the front and rear sliding components 312 to move along the front and rear guide rails 311.

[0066] Meanwhile, the vertical guide rail 211 is fixedly connected to the front and rear sliding members 312 (i.e., the front and rear sliding members 312 and the vertical guide rail 211 form a transmission connection), and the vertical sliding member 212 and the vertical guide rail 211 form a sliding engagement, allowing stable sliding along the extension direction of the vertical guide rail 211 (i.e., the vertical direction on the top side). The vertical drive assembly 22 is connected to the vertical sliding member 212 and is used to drive the vertical sliding member 212 to move along the vertical guide rail 211. The shooting platform 100 is fixedly connected to the vertical sliding member 212 and moves synchronously with the movement of the vertical sliding member 212.

[0067] When the position of the nozzle in the front-to-back direction needs to be adjusted, the front-to-back drive assembly 32 drives the front-to-back sliding member 312 to move along the front-to-back guide rail 311. Since the vertical guide rail 211, the vertical sliding member 212, and the firing platform 100 are all associated with the front-to-back sliding member 312, they will move synchronously in the front-to-back direction with the front-to-back sliding member 312, thereby achieving the position adjustment of the nozzle in the front-to-back direction. When the position of the nozzle in the vertical direction needs to be adjusted, the vertical drive assembly 22 drives the vertical sliding member 212 to move along the vertical guide rail 211, and the firing platform 100 moves synchronously in the vertical direction with the vertical sliding member 212, thereby achieving the position adjustment of the nozzle in the vertical direction.

[0068] In this embodiment, to further improve the stability and load-bearing capacity of the firing platform 100 during movement, two front and rear guide rails 311 are arranged in parallel. The two front and rear guide rails 311 are spaced apart along the width direction of the mounting component 1 (i.e., the horizontal direction perpendicular to the front and rear direction), and their extension directions are strictly consistent along the front and rear direction. Correspondingly, the front and rear sliding member 312 is a frame structure adapted to the two front and rear guide rails 311. Its bottom sides are respectively provided with sliding parts that correspond to the two front and rear guide rails 311. Through the sliding parts forming sliding engagement with the two front and rear guide rails 311 respectively, the front and rear sliding member 312 can slide synchronously and smoothly along the two front and rear guide rails 311 under the drive of the front and rear drive assembly 32, effectively avoiding the skew or sway that may occur in a single guide rail layout, and improving the rigidity of the front and rear movement.

[0069] Similarly, two vertical guide rails 211 are also arranged in parallel. The two vertical guide rails 211 are distributed at intervals along the length direction (i.e., the front-to-back direction) of the front-to-back sliding member 312, and their extension directions are strictly consistent along the vertical direction, and they are vertically fixed to the top of the front-to-back sliding member 312. Correspondingly, the vertical sliding member 212 is also a frame structure, with sliding parts (such as sliders) on both sides that correspond to and cooperate with the two vertical guide rails 211. The two sliding parts form sliding cooperation with the two vertical guide rails 211 respectively, so that the vertical sliding member 212 can slide synchronously and stably along the two vertical guide rails 211 under the drive of the vertical drive component 22. This avoids the side tilt that may occur when moving in the vertical direction in a single guide rail layout, and is especially suitable for the load-bearing requirements brought about by the weight of the firing table 100 itself, thus improving the stability of vertical movement.

[0070] Furthermore, in this embodiment, both the front and rear drive components 32 and the vertical drive component 22 are hydraulically driven to adapt to larger load requirements and improve the stability of power output. In other embodiments, the front and rear drive components 32 and the vertical drive component 22 may also employ any other linear drive structure from the prior art, which will not be elaborated upon here.

[0071] To further improve the accuracy of the adjustment, the centering adjustment device also includes a position detection component 4, which is configured to detect the movement position of the injection stage 100 in the vertical and forward / backward directions. As can be seen, the position detection component 4 can provide real-time and accurate feedback on the specific position of the injection stage 100 in both directions, providing a quantitative basis for the adjustment of the forward / backward translation mechanism 3 and the vertical translation mechanism 2. This allows the adjustment process to be based on clear position parameters, avoiding the ambiguity of manual judgment and thus improving the accuracy of the nozzle-sprue bushing connection.

[0072] Specifically, the position detection component 4 includes a vertical position electronic ruler 41 and a front-rear position electronic ruler 42. The vertical position electronic ruler 41 cooperates with the vertical translation mechanism 2 to detect the vertical movement of the firing platform 100. The front-rear position electronic ruler 42 cooperates with the front-rear translation mechanism 3 to detect the front-rear movement of the firing platform 100.

[0073] With this setup, the electronic ruler (such as an optical scale or magnetic scale) is itself a high-precision linear position detection element. It can convert electrical signals through continuous displacement and output position data with micron-level or even higher precision. Addressing the alignment requirements between the injection stage 100 and the mold 200's sprue bushing (where minute deviations can lead to material leakage, wear, etc.), the vertical position electronic ruler 41 and the front-rear position electronic ruler 42 independently detect vertical and front-rear directions respectively. This accurately captures positional changes in each direction, providing precise feedback for subsequent adjustments and ensuring alignment accuracy.

[0074] It should be noted that the electronic ruler consists of a fixed end and a moving end. The fixed end is connected to a guide rail or other fixed structure, while the moving end is connected to a sliding component and moves with it. During detection, the relative displacement between the two is sensed and converted into an electrical signal, thereby accurately reflecting the real-time position of the mapping stage 100 in the corresponding direction. The electronic ruler is existing technology, and this implementation does not make any improvements to its structure and working principle, so it will not be described in detail here.

[0075] In this embodiment, the fixed end of the front and rear position electronic ruler 42 is connected to the mounting component 1 (fixed relative to the front and rear guide rails 311), and the moving end is connected to the front and rear sliding component 312. When the front and rear sliding component 312 moves, it senses the relative displacement and converts it into an electrical signal, indicating the front and rear position of the anti-mapping stage 100 (because the vertical component and the shooting stage 100 move synchronously with it). The fixed end of the vertical position electronic ruler 41 is connected to the vertical guide rail 211, and the moving end is connected to the vertical sliding component 212. Its sensed displacement is converted into an electrical signal, indicating the vertical position of the anti-mapping stage 100.

[0076] To further improve the stability of movement, the centering adjustment device also includes a jetting bracket 5. The jetting bracket 5 is used to connect the front and rear sliding members 312 to the vertical guide rail 211, or to connect the vertical sliding members 212 to the front and rear guide rails 311.

[0077] When the front and rear sliding member 312 is fixedly connected to the shooting bracket 5, the shooting bracket 5 is provided with a vertical guide rail 211, and the vertical sliding member 212 is connected to the shooting platform 100, so that the front and rear sliding member 312 drives the vertical guide rail 211 to move synchronously through the shooting bracket 5, and the vertical sliding member 212 drives the shooting platform 100 to move along the vertical guide rail 211. When the vertical sliding member 212 is fixedly connected to the shooting bracket 5, the shooting bracket 5 is provided with a front and rear guide rail 311, and the front and rear sliding member 312 is connected to the shooting platform 100, so that the vertical sliding member 212 drives the front and rear guide rail 311 to move synchronously through the shooting bracket 5, and the front and rear sliding member 312 drives the shooting platform 100 to move along the front and rear guide rail 311.

[0078] Understandably, the injection support 5 optimizes the force transmission path by fixing the front and rear sliding parts 312 to the vertical guide rail 211 or the vertical sliding parts 212 to the front and rear guide rails 311, reducing stress concentration and shaking during movement. This makes the injection table 100 move more smoothly in the front-to-back and vertical directions, improving adjustment stability and facilitating precise docking between the nozzle and the gate. Furthermore, the two connection methods further expand the selection space for the device's structural layout, allowing for flexible adaptation to the spatial constraints of different injection molding equipment and enhancing the device's applicability to diverse equipment.

[0079] In this embodiment, the front and rear guide rails 311 include a base block 3111, multiple shims 3112, and wear-resistant blocks 3113. The base block 3111 is mounted on the mounting member 1 via the shims 3112, and the wear-resistant blocks 3113 are fixed to the top surface of the base block 3111 to form a sliding groove that extends through the front and rear directions. The front and rear sliding members 312 slide and engage with the sliding groove. The height of the sliding groove formed by the base block 3111 and the wear-resistant blocks 3113 can be adjusted by increasing or decreasing the number of shims 3112, thereby adjusting the fit clearance between the front and rear sliding members 312 and the sliding groove.

[0080] In injection molding production, the front and rear sliding parts 312 slide relative to the slide groove at high frequency for a long time. Due to wear, the mating clearance is prone to increase, causing sliding wobbling, reduced positioning accuracy, and affecting nozzle alignment. By adding or removing shims 3112 to adjust the height of the slide groove, the wear clearance can be easily compensated without replacing the entire guide rail. This meets the precision maintenance needs after long-term use and reduces equipment downtime for maintenance.

[0081] Furthermore, there may be slight deviations in the installation references of different injection molding equipment, or the fitting accuracy needs to be recalibrated after replacing the wear-resistant block 3113 or the sliding component. The addition or removal of the gasket 3112 does not require complex processing, and the tightness of the fit between the slide and the sliding component can be quickly adjusted on-site to accommodate the installation errors of different equipment or the accuracy calibration after component replacement, thereby improving the installation flexibility of the device.

[0082] It is worth noting that the wear-resistant block 3113 is in direct contact with the sliding parts and can be made of high-hardness wear-resistant materials (such as hardened steel or engineering ceramics), while the base block 3111 can be made of ordinary materials, reducing the overall manufacturing cost. Furthermore, the wear-resistant block 3113 can be replaced individually after wear, and the clearance accuracy can be restored by adjusting it with the shim 3112, avoiding the need to replace the entire guide rail, significantly reducing long-term operating costs and meeting the economic requirements of injection molding production.

[0083] This embodiment also provides a top-side injection molding machine, which includes a mold 200, an injection stage 100, and the aforementioned centering adjustment device. The centering adjustment device is disposed between the mold 200 and the injection stage 100, and is used to adjust the relative position of the injection stage 100 and the mold 200 so that the nozzle of the injection stage 100 aligns with the gate of the mold 200. It is understood that, compared to the traditional method of relying on manual adjustment of the injection unit or mold 200 position, the top-side injection molding machine including the aforementioned centering adjustment device reduces the tediousness of manual operation and meets the needs of cost reduction and efficiency improvement in large-scale production.

[0084] Further, the injection unit 100 includes a support member 110, a feeding assembly 120, a plasticizing assembly 130, and an injection assembly 140.

The hopper 1201 communicates with the plasticizing assembly 130 through the hopper seat 1202 to supply raw materials. The plasticizing assembly 130 is disposed on the support member 110 and includes a melt motor 1301 and an injection screw 1302. The melt motor 1301 drives the injection screw 1302 to rotate to melt the raw materials. The injection assembly 140 is mounted on the support member 110. The injection assembly 140 includes an injection head plate 1401, an injection tail plate 1402, and an injection cylinder 1403. The injection head plate 1401 and the injection tail plate 1402 are arranged opposite to each other. The injection cylinder 1403 is connected between the injection head plate 1401 and the injection tail plate 1402 and is used to drive the injection screw 1302 to move axially to complete the injection action.

[0085] With this configuration, the feeding component 120 is precisely connected to the plasticizing component 130 via the hopper seat 1202, ensuring a stable raw material supply path. The melting motor 1301 of the plasticizing component 130 drives the injection screw 1302 to efficiently melt the raw material, and the injection cylinder 1403 of the injection component 140 drives the screw to move axially to complete the injection. The various links are closely connected, reducing raw material transport losses and time waste, and improving injection molding efficiency. In addition, the plasticizing component 130, injection component 140, and feeding component 120 are integrated into the support component 110, resulting in a clear structure that facilitates individual disassembly and maintenance, reducing maintenance difficulty.
