Description

Technical Field

[0001] The utility model relates to the field of injection molding devices, and particularly relates to a support structure for a base. Background Art

[0002] With the development of production and the progress of technology, the application of injection molding machines has become increasingly important in the manufacturing industry. Injection molding machines are mainly used to produce plastic products, and usually require efficient and precise operation. Generally, a horizontal injection molding machine places the mold on the base, and then sets the injection head on one side of the mold. Thus, during the operation of the injection molding machine, if the base is unstable, it may be inclined or displaced, which will not only damage the equipment, but also may cause production accidents. Therefore, there are extremely high requirements for the stability of the base supporting the operation of the injection molding machine; since different production tasks may require the use of molds of different heights, and since the position of the injection head cannot be adjusted, for molds of different heights, generally, the height of the base needs to be finely adjusted to align the molds of different heights with the injection head. Therefore, while the injection molding machine requires a stable base, it also needs an easily operable adjustment device to enable the injection molding machine to quickly adapt to molds of different heights by adjusting the base.

[0003] For example, in the patent document with the patent application number 202020442012.0 and the publication date of December 22, 2020, which discloses a technical field of a structurally stable injection molding machine frame, and discloses a structurally stable injection molding machine frame, including a base, the upper surface of the base is fixedly welded with a chassis, the front surface of the base is fixedly welded with a fixed seat, a cavity is opened inside the fixed seat, a support rod is arranged inside the cavity, the support rod is fixedly connected with the fixed seat through a first connecting bolt, a support foot is arranged at the bottom of the support rod, the support foot is detachable from the support rod, the front surface of the chassis is fixedly welded with a mounting seat, and a connecting rod is arranged inside the mounting seat. By setting the support rod, the fixed seat, the first connecting bolt, the mounting seat and the connecting rod, it has the functions of adjusting the height and facilitating handling, which is convenient for adjusting the height in the case where the ground height of the frame is uneven, and at the same time increases the convenience of the machine during handling.

[0004] In the above literature, an adjustable device is provided on the injection molding machine frame to make the injection molding mechanism adjustable, which facilitates the handling of the injection molding machine. During use, according to the stability of the frame, the slightly swaying support rod can be pulled downward and fixed to the fixed seat through the first connecting bolt, so that the support feet are closely attached to the ground until the frame stops swaying. After use, loosen the first connecting bolt and move the support rod and the support feet upward. When the casters contact the ground, fix the first connecting bolt again. It can be seen that during the use of the injection molding machine, there is no auxiliary support, and it only relies on the contact between the support feet and the ground to maintain stability. Moreover, the support feet are located on the four sides of the support frame. For heavy objects, the gravity is mainly concentrated in the middle, resulting in excessive pressure at the position of the support feet. And the support feet are connected to the support frame by a rod, and the contact area between the rod and the support feet is small, so it is easy to bend or break at the position of the rod and the support feet, resulting in poor connection reliability at the connection of the support feet. And when adjusting the height, it is still necessary to rely on an external support device to support the middle of the support frame, otherwise it is impossible to ensure the connection position between the rod and the support frame, and thus it is impossible to ensure the reliability of the adjustment, and the operation is complex. Summary of the Invention

[0005] The utility model provides a support structure for a base, which is simple to operate, convenient to use, and has a long service life.

[0006] To achieve the above object, a technical solution of one aspect of the utility model is: a support structure for a base, including a base main body, the base main body includes a reinforcing plate and an auxiliary support device, the reinforcing plate is arranged in the middle of the base main body, the reinforcing plate is fixedly provided with more than two auxiliary support devices, the auxiliary support device includes an upper support plate, a lower support plate and a support assembly, the reinforcing plate is located between the upper support plate and the lower support plate, the upper support plate is fixedly connected to the upper side surface of the reinforcing plate, the support assembly includes a support rod and a guide rod, one end of the support rod passes through the upper support plate and the reinforcing plate and then abuts against the lower support plate, the support rod is slidably connected to the upper support plate, a fastener is arranged at one end of the support rod close to the upper support plate, the guide rods are located on both sides of the support rod, and the guide rods are detachably connected to the upper support plate and the lower support plate.

[0007] With the above settings, a reinforcing plate and an auxiliary support are provided at the bottom of the base body to improve the stability of the base body. The upper support plate is fixedly connected to the reinforcing plate. Through the fixed connection of the support rod to the lower support plate, when it is necessary to increase the height of the entire base, the lower support plate is placed corresponding to the upper support plate, and then the fastener is unscrewed. After the support rod moves downward to a determined position and the lower end of the support rod is connected to the lower support plate and the upper end of the support rod is locked by the fastener, the height position adjustment of the base is realized. At the same time, the guide rod is placed in the upper support plate and the lower support plate to play a guiding role, and then after reaching the required height, the guide rod is fixed to the upper support plate and the lower support plate, thereby strengthening the strength of the lower support plate fixed to the reinforcing plate. The lower support plate is in contact with the ground, and then the base is lifted by the height of the support rod. When it is not necessary to increase the height of the entire base, the fastener is unscrewed, and after the support rod moves upward to a determined position, the support rod is separated from the ground, so that the support rod does not support the base. Since the auxiliary support device is provided on the reinforcing plate located in the middle of the base, the support effect on the base can be increased. At the same time, since one end connected to the support rod is provided with a lower support plate, the support area of the auxiliary support device is increased. The other end of the support rod is locked by a fastener, so that the force of the support rod acts on the upper support plate, increasing the support force at the upper end of the support rod and ensuring the support effect. The height of the support rod can be adjusted according to different usage situations, providing the adaptability of the injection molding machine in different scenarios.

[0008] Further, one end of the support rod passes through the upper support plate and the reinforcing plate and abuts against the lower support plate.

[0009] With the above settings, by abutting one end of the support rod against the lower support plate, when it is necessary to increase the height of the entire base, the lower support plate is placed on the ground corresponding to the upper support plate, and then the fastener is unscrewed. After the support rod moves downward to a determined position and the lower end of the support rod abuts against the lower support plate and the upper end of the support rod is locked by the fastener, the height position adjustment of the base is realized. At the same time, the guide rod is placed in the upper support plate and the lower support plate to play a guiding role, and then after reaching the required height, the guide rod is fixed to the upper support plate and the lower support plate, thereby strengthening the strength of the lower support plate fixed to the reinforcing plate. When it is not necessary to increase the height of the entire base, the lower support plate is placed on the ground corresponding to the upper support plate, and the fastener is unscrewed. After the support rod moves upward to a determined position, one end of the support rod is separated from the lower support plate, so that the lower support plate is not fixed to the base, reducing the weight of the base.

[0010] Further, one end of the support rod passes through the upper support plate and the reinforcing plate and is fixedly connected to the lower support plate.

[0011] With the above settings, one end of the support rod is fixedly connected to the lower support plate. When it is necessary to increase the height of the entire base, the fastener is unscrewed so that the support rod moves downward to a determined position and the lower end of the support rod drives the lower support plate to abut against the ground. Then, the upper end of the support rod is locked through the fastener, thereby realizing the adjustment of the height position of the base. At the same time, the guide rod is placed inside the upper support plate and the lower support plate to play a guiding role. Then, after reaching the required height, the guide rod is fixed to the upper support plate and the lower support plate, thereby strengthening the strength of the lower support plate fixed on the reinforcement plate. When it is not necessary to increase the height of the entire base, the lower support plate is placed on the corresponding ground of the upper support plate, and the fastener is unscrewed so that the support rod moves upward to a determined position. Then, one end of the support rod is disengaged from the lower support plate, and the support rod drives the lower support plate to disengage from the ground. Since the auxiliary support device is arranged on the reinforcement plate located in the middle of the base, the support effect on the base can be increased. At the same time, since a lower support plate is arranged at one end connected to the support rod, the support area of the auxiliary support device is increased. And the other end of the support rod is locked through the fastener, so that the force of the support rod acts on the upper support plate, increasing the support force at the upper end of the support rod and ensuring the support effect. The height of the support rod can be adjusted according to different usage situations, providing the adaptability of the injection molding machine in different scenarios.

[0012] Further, the axis of the support rod and the axis of the guide rod are located on the same straight line.

[0013] With the above settings, the axes of the support rod and the guide rod are located on the same straight line, making the entire structure more stable and rigid, reducing bending and deformation under load, and helping to disperse the load and reduce local stress.

[0014] Further, two or more of the above-mentioned auxiliary support devices are arranged on the reinforcement plate in a straight line.

[0015] With the above settings, the auxiliary support devices arranged in a straight line can distribute the support force more evenly, improving the overall stability of the base during the operation of the injection molding machine.

[0016] Further, the upper support plate and the lower support plate are provided with fixing holes for the guide rod to match.

[0017] With the above settings, the guide rod of the upper support plate passes through the reinforcement plate and is detachably connected to the lower support plate through the fixing hole. When the base is raised, the lower support plate is placed on the ground, and then when the support rod is adjusted to abut against the lower support plate, the guide rod is inserted into the fixing hole to realize the fixed connection between the upper support plate and the lower support plate, making the connection between the upper support plate and the lower support plate firm and effectively preventing displacement or inclination under external force.

[0018] Further, the fastener is a head, the support rod is a screw rod, and when the base is adjusted to a fixed height, the fastener locks the support rod and the fastener abuts against the upper surface of the upper support plate.

[0019] With the above arrangement, the fastener on the support rod abuts against the upper surface of the lower support plate to effectively support the base, and the support rod is locked by the fastener. At the same time, the fastener can also act on the upper support plate to ensure the supporting effect of the support rod on the upper support plate.

[0020] Further, a through hole matching the support rod is provided on the upper support plate, and the support rod passes through the through hole and the reinforcement plate and abuts against the upper end surface of the lower support plate.

[0021] With the above arrangement, by providing a through hole on the upper support plate, it is convenient for the support rod to be connected to the upper support plate.

[0022] Further, a limiting plate is provided at one end of the guide rod close to the upper support plate, and the limiting plate abuts against the upper support plate.

[0023] With the above arrangement, the guide rod realizes the limit of the movement of the guide rod in the fixing hole through the limiting plate, ensuring that the guide rod is reliably limited in the fixing hole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0031] Embodiment 1.

[0032] AsFigures 1 to 4 As shown in the figure, a support structure for a base includes a base main body 1, the base main body 1 includes a reinforcing plate 11, an auxiliary support device 2, and a support column 12. The reinforcing plate 11 is fixedly provided with the auxiliary support device 2. The reinforcing plate 11 is arranged in the middle of the base main body 1. The auxiliary support device 2 includes an upper support plate 23, a lower support plate 24, and a support assembly. The upper support plate 23 is fixedly connected to the reinforcing plate 11. The support assembly includes a support rod 21, a guide rod 22, and a fastener. The support rod 21 is detachably connected to the fastener. The support rod 21 is slidably connected to the upper support plate 23. One end of the support rod 21 passes through the upper support plate 23 and is fixedly connected to the lower support plate 24. The guide rod 22 is arranged on both sides of the support rod 21. The guide rod 22 is slidably connected to the upper support plate 23. The guide rod 22 passes through the upper support plate 23 and is detachably connected to the lower support plate 24. A reinforcing plate 11 and an auxiliary support are arranged at the bottom of the base main body 1 to improve the stability of the base main body 1. The upper support plate 23 is fixedly connected to the reinforcing plate 11. The support of the upper support plate 23 is completed by the abutment of the support rod 21 against the lower support plate 24 and the detachable connection of the guide rod 22 to the lower support plate 24. Since the guide rod 22 and the support rod 21 are detachably connected to the upper support plate 23, the height of the support rod 21 can be adjusted according to different usage situations, providing the adaptability of the injection molding machine in different scenarios.

[0033] As Figures 1 - 2 shown in the figure, the axes of the support rod 21 and the guide rod 22 are located on the same straight line, and the axes of the support rod 21 and the guide rod 22 are arranged in parallel, making the whole structure more stable and rigid, reducing bending and deformation under load, and helping to disperse the load and reduce local stress.

[0034] In this embodiment, three auxiliary support devices are provided. The three auxiliary support devices are located on the reinforcing plate and are on the same straight line. The auxiliary supports arranged in a straight line can distribute the supporting force more evenly, improving the overall stability of the base during the operation of the injection molding machine.

[0035] As Figure 2 shown in the figure, the support column 12 is fixedly provided with a table foot seat 13. The table foot seat 13 is rotatably connected to the table foot. By providing the table foot seat 13 on the base, the height of the table foot can be adjusted through the table foot seat 13, which is the same as the adjustable-height support foot structure disclosed in Patent Application No. 202020442012.0. Its specific structure is prior art and will not be elaborated here.

[0036] As Figures 3 - 4As shown, the lower support plate 24 is provided with a fixing hole 241, and the guide rod 22 of the upper support plate 23 passes through the reinforcing plate 11 and is then detachably connected to the lower support plate 24 through the fixing hole 241. The fixing hole is a pin hole or a threaded hole, and the guide rod 22 is a pin or a screw. The upper support plate 23 is provided with a through hole 210 corresponding to the support rod 21, and the support rod 21 is provided with a screw portion 211, and the fastener is a head. The support rod 21 and the fastener form a bolt, and after moving to a suitable height, the fastener locks the support rod 21 and the bottom of the fastener abuts against the upper end surface of the upper support plate, thereby ensuring the reliability of the connection. In addition, a limiting plate 221 is provided at one end of the guide rod 22, and the limiting plate 221 is vertically arranged with the guide rod 22.

[0037] The working principle of the utility model is as follows: when the base is lowered, the lower support plate 24 is suspended above the ground. When the base needs to be raised, the fasteners can be unscrewed and the support rod 21 can be moved to make the lower support plate 24 descend and contact the ground, thereby completing the movement of the lower support plate 24. At the same time, the guide rod 22 can be placed in the fixing hole 241, so that the fixing hole 241 and the guide rod 22 can be used to guide the movement of the lower support plate 24. When moving to the required height, the guide rod can be used to firmly connect the upper support plate 23 and the lower support plate 24, thereby effectively preventing displacement or tilting under the action of external force.

[0038] The support rod 21 extends out of the upper support plate 23 and is fixedly connected to the upper surface of the lower support plate 24. The support rod 21 is connected to the upper surface of the lower support plate 24 to effectively support the base.

[0039] When the support height needs to be lowered, the fixing effect of the guide rod on the upper support plate and the lower support plate is loosened. It is only necessary to unscrew the fasteners and then move the support rod 21 upward so that the support rod 21 drives the lower support plate to move upward so that the lower support plate is off the ground.

[0040] Embodiment 2.

[0041] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, the other end of the support rod 21 is in contact with the lower support plate 24 instead of being fixedly connected.

[0042] Working principle of the utility model: When it is necessary to increase the height of the entire base, place the lower support plate 24 on the corresponding ground of the upper support plate 23, and then unscrew the fastener so that the support rod 21 moves downward to a determined position and the lower end of the support rod 21 abuts against the lower support plate 24 and the upper end of the support rod 21 is locked by the fastener, thereby realizing the adjustment of the height position of the base. At the same time, place the guide rod into the upper support plate and the lower support plate to play a guiding role, and then fix the guide rod 22 on the upper support plate and the lower support plate after reaching the required height, thereby strengthening the strength of the lower support plate fixed on the reinforcement plate. When it is not necessary to increase the height of the entire base, place the lower support plate 24 on the corresponding ground of the upper support plate, unscrew the fastener, and when the support rod 21 moves upward to a determined position, one end of the support rod is separated from the lower support plate, thereby realizing that the support rod drives the lower support plate not to contact the ground.
