Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine technology, specifically relating to a rodless guide plate support structure. Background Technology

[0002] In the field of precision injection molding technology, high-precision injection molding machines are key equipment for manufacturing high-precision plastic products. One of its core components, the design of the two-platen structure, directly affects the clamping accuracy, mold life, and overall performance of the injection molding machine. Traditional high-precision injection molding machines generally use linear rolling guide pairs as the support structure at the bottom of the two-platen. This design aims to reduce friction through rolling contact, improve motion accuracy and efficiency, and simultaneously distribute the weight load of the two-platen and the mold, ensuring stability and reliability during the injection molding process.

[0003] However, the existing linear rolling guide pair installation scheme has several limitations. Specifically, the linear rolling guide pair is usually directly and fixedly installed on the bottom of the second plate without the necessary adjustment mechanism. This means that the perpendicularity between the bottom of the second plate and the code mold surface depends entirely on the machining accuracy. Therefore, even under strict machining conditions, there may still be some deviation in the perpendicularity between the bottom of the second plate and the code mold surface.

[0004] Furthermore, since the second platen needs to bear the weight of the mold and injection material during the injection molding process and reciprocates along the tie rod guide within the frame, its load is extremely high. Although the linear rolling guide pair can effectively share this load, if the perpendicularity deviation caused by processing errors is not corrected, it will directly affect the parallelism between the second platen and the head platen. The deviation in parallelism will not only reduce the accuracy and stability of the clamping mechanism, but may also cause problems such as accelerated mold wear and increased defects in injection molded products, seriously affecting the overall performance and product quality of the injection molding machine.

[0005] Therefore, a two-plate support structure without pull-down guidance is needed to solve the precision problem in the injection molding process. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a rodless guide two-plate support structure, which solves the problem of precision errors during existing two-plate injection molding.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A rodless guide plate support structure includes a fixed base, a transition adjustment block, a slider, and a guide rail disposed at the bottom of the two plates. Vertically, from the top to the bottom of the two plates, the fixed base, transition adjustment block, slider, and guide rail are arranged sequentially. The fixed base has through-screw holes on both sides, and an adjustment rod is installed in any of the through-screw holes. The adjustment rod is used to indirectly adjust the vertical height of the slider. The fixed base has an abutment portion, and one side of the transition adjustment block abuts against the abutment portion. The bottom of the transition adjustment block has a downward-opening positioning groove, and the slider is installed in the positioning groove and the guide rail, with the bottom of the slider and the bottom of the guide rail located on the same horizontal plane. The abutment portion and the positioning groove are used to adjust the horizontal distance between the transition adjustment block and the slider.

[0009] Preferably, there are two sliders, symmetrically arranged on the transition adjustment block, and mounted on the transition adjustment block by a first screw.

[0010] Preferably, the transition adjustment block is mounted on the fixed base by a second screw, and there are several second screws, all located between the sliders on both sides.

[0011] Preferably, the adjusting rod is hollow inside and a first bolt is installed thereon, the first bolt being used to fix and lock the adjusting rod.

[0012] Preferably, the fixing base is further provided with a side pressure block, which is installed on the fixing base by a third screw. The side pressure block is located on the side of the fixing base away from the abutment portion and forms the installation space of the transition adjustment block with the abutment portion. The side pressure block is used to adjust the horizontal position of the transition adjustment block.

[0013] Preferably, the fixing base is integrally formed with the two plates.

[0014] The beneficial effects of this utility model are as follows:

[0015] The proposed solution, by introducing components such as adjusting rods and transition adjusting blocks, enables precise adjustment of the vertical height and horizontal distance of the bottom of the second plate even without tie rod guidance. This adjustment method not only improves the verticality accuracy between the bottom of the second plate and the code mold surface, but also enhances the stability and load-bearing capacity of the entire structure.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figures 1-3 As shown, a rodless guide plate support structure includes a fixed seat 1, a transition adjustment block 2, a slider 3, and a guide rail 4 disposed at the bottom of the two plates; in the vertical direction, from the top to the bottom of the two plates, the fixed seat 1, the transition adjustment block 2, the slider 3, and the guide rail 4 are arranged in sequence, and the vertical layout ensures the stability and support of the structure.

[0023] The fixed base 1 has through screw holes on both sides, and an adjusting rod 5 is installed in either through screw hole. The adjusting rod 5 is used to indirectly adjust the vertical height of the slider 3. The fixed base 1 has an abutment part 11, and one side of the transition adjusting block 2 abuts against the abutment part 11. The bottom of the transition adjusting block 2 has a downward-opening positioning groove 21. The slider 3 is installed in the positioning groove 21 and the guide rail 4, with the bottom of the slider 3 and the bottom of the guide rail 4 on the same horizontal plane. The abutment part 11 and the positioning groove 21 are used to adjust the horizontal distance between the transition adjusting block 2 and the slider 3. When it is necessary to adjust the vertical height of the bottom of the two plates, the position of the adjusting rod 5 in the through screw hole can be changed by rotating it. The up and down movement of the adjusting rod 5 will push or pull the transition adjusting block 2, thereby changing the vertical position of the slider 3 relative to the guide rail 4. This adjustment method can achieve precise adjustment of the vertical height of the bottom of the two plates. By changing the position of the adjusting rod 5 in the through screw hole and utilizing the flexibility of the positioning groove 21, the horizontal distance between the transition adjusting block 2 and the slider 3 can be finely adjusted. This adjustment method helps optimize the perpendicularity of the bottom of the second plate to the code mold surface and reduce errors caused by processing deviations. During the movement of the second plate, the slide rail is responsible for sharing the load and ensuring the smooth movement of the second plate on the frame. At the same time, the stability and reliability of the entire structure can be further improved through the cooperation of the adjusting rod 5 and the transition adjusting block 2.

[0024] In summary, the solution proposed in this application, by introducing components such as the adjusting rod 5 and the transition adjusting block 2, enables precise adjustment of the vertical height and horizontal distance of the bottom of the two plates even without the guide rod. This adjustment method not only improves the perpendicularity accuracy between the bottom of the two plates and the code mold surface, but also enhances the stability and load-bearing capacity of the entire structure.

[0025] In one embodiment, there are two sliders 3, symmetrically arranged on the transition adjustment block 2 and mounted on the transition adjustment block 2 by a first screw. This symmetrical layout ensures the balance and uniform distribution of force, which helps to reduce wear or damage caused by uneven force. The sliders 3 are firmly mounted on the transition adjustment block 2 by the first screw to ensure that they will not loosen or shift during operation. When it is necessary to adjust the position or angle of the two plates, the sliders 3 are moved to slide on the slide rail, thereby realizing the fine adjustment or precise positioning of the two plates.

[0026] In one embodiment, the transition adjustment block 2 is mounted on the fixed base 1 by a second screw, and there are several second screws, all located between the sliders 3 on both sides.

[0027] In one embodiment, the adjusting rod 5 is hollow inside and a first bolt 6 is installed thereon. The first bolt 6 is used to fix and lock the adjusting rod 5 inside the adjusting rod 5. When it is necessary to adjust the position or angle of the adjusting rod 5, the first bolt 6 can be loosened so that the adjusting rod 5 can move within the allowable range. Once the desired position or angle is adjusted, the first bolt 6 is tightened to fix and lock the adjusting rod 5, ensuring that it will not move or deform due to external force during use.

[0028] In one embodiment, the mounting base 1 is further provided with a side pressure block 7. The side pressure block 7 is mounted on the mounting base 1 by a third screw. The side pressure block 7 is located on the side of the mounting base 1 away from the abutment portion 11, and together with the abutment portion 11, forms the installation space for the transition adjustment block 2. The side pressure block 7 is used to adjust the horizontal position of the transition adjustment block 2. The side pressure block 7 and the abutment portion 11 of the mounting base 1 together form a closed space, which is just enough to install the transition adjustment block 2. The design of the transition adjustment block 2 allows for fine adjustment of its horizontal position within a certain range to adapt to different connection or support requirements. Horizontal position adjustment: When it is necessary to adjust the horizontal position of the transition adjustment block 2, the third screw can be loosened, allowing the side pressure block 7 to move slightly on the mounting base 1. By precisely adjusting the position of the side pressure block 7, the horizontal position of the transition adjustment block 2 can be indirectly changed. Once the desired position is reached, the third screw is tightened to fix the side pressure block 7 and the transition adjustment block 2 in the current position.

[0029] In one embodiment, the fixing base 1 and the second plate are integrally formed. The integral forming design ensures that there are no gaps at the connection between the fixing base 1 and the second plate, thereby avoiding performance degradation caused by loosening or wear of the connecting parts. During the forming process, the fixing base 1 and the second plate can be processed in the same process, reducing the errors caused by multiple processing and assembly.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
