The connection relationship of the above components will be described in detail below.
The guide rod mounting portion 100 is formed with a guide rod mounting hole 110 penetrating therethrough, and in the present embodiment, the guide rod mounting portion 100 may be approximately cylindrical in shape. First and second ears 200 and 300 are formed on both sides of the guide bar mounting part 100, respectively, that is, the first and second ears 200 and 300 are respectively located on both sides of the axis of the guide bar mounting hole 110, and first and second ears 200 and 300 are respectively formed with first and second tie bar mounting holes 210 and 310.
In this embodiment, the guide rod mounting hole 110 is penetrated by a guide rod (not shown) of the injection molding machine when the injection platen back plate is mounted on the injection molding machine (not shown), and the first tie bar mounting hole 210 and the second tie bar mounting hole 310 are penetrated by a first tie bar (not shown) and a second tie bar (not shown) when mounted on the injection molding machine.
In this embodiment, the rear plate of the injection platform may have a symmetrical structure with respect to the central axis. That is, the guide bar mounting holes 110 are symmetrical with respect to the central axis plane of the back plate of the injection table, and the first and second ears 200 and 300, the first and second tie bar mounting holes 210 and 310 are also symmetrical with respect to the central axis plane of the back plate of the injection table. The central axis plane of the back plate of the injection table referred to herein means a plane passing through the axis of the guide rod installation hole 110 and perpendicular to the horizontal plane. The symmetrical arrangement ensures that the injection platform rear plate achieves standardization to a certain extent, thereby ensuring the matching precision of the injection platform rear plate and the injection platform, the guide rod, the first pull rod and the second pull rod to a certain extent.
In addition, the guide rod mounting hole 110, the first pull rod mounting hole 210 and the second pull rod mounting hole 310 may be respectively formed along outer peripheries thereof with a plurality of fastening through holes (not shown) penetrating the guide rod mounting portion 100, the first ear portion 200 and the second ear portion 300, and fastening screws respectively penetrate the fastening through holes to be matched with female screw fastening holes reserved on the injection table, so as to mount the injection table rear plate on the injection table.
According to the state of the injection table back plate mounted on the injection table described above, with reference to the injection table, in the axial direction of the guide rod mounting portion 100, the side of the injection table back plate facing the injection table is defined as the mounting side, and the side of the injection table back plate away from the injection table is defined as the non-mounting side. Thus, fig. 1 shows a schematic view of the mounting side of the shooting table backplate; FIG. 2 shows a schematic view of the unassembled side of the shooting table backplate; the left side in fig. 3 is the mounting side of the injection stage rear plate, and the right side is the non-mounting side of the injection stage rear plate.
The above definitions of the mounting side and the non-mounting side are for convenience of description of the drawings and features described below, and do not mean that the side of the injection platen back plate away from the injection platen is not provided with other components related to the injection molding machine.
In this embodiment, as shown in fig. 1, a first concave portion and a second concave portion are formed on the fitting side of first ear 200 and second ear 300, and first tie rod mounting hole 210 and second tie rod mounting hole 310 are respectively formed in the first concave portion and the second concave portion. The purpose of providing two recesses is to reduce the overall weight of the shooting table backplate.
The injection platform back plate in the embodiment can be obtained by casting a blank and then machining the blank. Specifically, the material of the injection platform back plate can be cast iron, and machining allowance is reserved for a blank obtained by casting so as to facilitate subsequent machining.
Based on the above-described features, when the injection platform rear plate is installed on the injection platform and the injection molding machine is operated, the first pull rod and the second pull rod respectively apply pulling forces to the first lug part 200 and the second lug part 300, and the direction of the pulling forces is along the extending direction of the pull rods and is directed from the non-assembly side to the assembly side of the injection platform rear plate. In this case, since cast iron has poor tensile properties, breakage may occur at portions where first and second ears 200 and 300 are continuous with guide bar attaching portion 100.
Therefore, as shown in fig. 1, in the present embodiment, on the fitting side of the injection stand rear plate, a first reinforcing portion 220 and a second reinforcing portion 320 are provided at continuous portions of the first ear portion 200 and the second ear portion 300 and the guide bar attaching portion 100, respectively. Because the two reinforcing parts can also be integrally formed with the injection platform rear plate through casting, the material can also be cast iron, according to the stress conditions of the first lug part 200 and the second lug part 300 in the working process of the injection molding machine, the stress borne by the two reinforcing parts is pressure, and because the compression resistance of the cast iron is better, the arrangement effectively improves the stress concentration conditions of the two parts, so that the reliability of connection between the continuous parts of the first lug part 200 and the second lug part 300 and the guide rod installation part 100 is effectively ensured, and the tensile property of the injection platform rear plate is enhanced.
However, not limited thereto:
first, even on the non-mounting side of the injection stage rear plate, reinforcing portions may be provided at the connecting portions between the first and second lug portions 200 and 300 and the guide bar attaching portion 100, and the reliability of connection can be further increased to some extent although the forces applied to the reinforcing portions at these two portions are mainly tensile forces.
Secondly, in the present embodiment, the size and shape of the two reinforcing portions are not particularly limited as long as the reinforcing portions can sufficiently receive the force applied to the first and second ear portions 200 and 300 in the extending direction of the tie bar, and do not interfere with the first and second tie bar mounting holes 210 and 310.
Third, as shown in fig. 3, in the present embodiment, the connection reliability can be further increased by increasing the areas of the continuous portions of the first and second ears 200 and 300 and the guide bar mounting portion 100.
The injection table back plate in this embodiment further includes a first guide sleeve 400 and a second guide sleeve 500 connected to the guide bar mounting part 100 through a first leg 420 and a second leg 520, respectively, the first guide sleeve 400 and the second guide sleeve 500 are disposed below the first ear 200 and the second ear 300, respectively, and the first guide sleeve 400 and the second guide sleeve 500 are further formed with a first guide groove 410 and a second guide groove 510 extending in the extending direction thereof, respectively. The first guide groove 410 and the second guide groove 510 are respectively sleeved on a first guide rail and a second guide rail of an injection molding machine, which will be described below, so that the injection table back plate can slide along the first guide rail and the second guide rail.
In this embodiment, the first guide rail and the second guide rail of the injection molding machine are arranged in parallel, and the shapes of the first guide rail and the second guide rail can be cylindrical, so the first guide groove 410 and the second guide groove 510 can be arranged in parallel, in addition, the inner side surfaces of the first guide groove 410 and the second guide groove 510, which are respectively matched with the first guide rail and the second guide rail, can be arc surfaces, and in order to prevent the guide grooves from being separated from the guide rails along the radial direction of the guide rails, when the arc surfaces of the guide grooves are observed along the axes of the guide grooves, the arcs of the corresponding arc surfaces can be major arcs.
In this embodiment, based on the above installation manner, the first guide sleeve 400 and the second guide sleeve 500, the first leg 420 and the second leg 520, and the first guide groove 410 and the second guide groove 510 may also be symmetrical about the central axis plane, so as to ensure the accuracy in the installation and matching process, and to make the quality of the back plate of the injection table uniform, and further make the back plate slide smoothly.
In addition, a lubricating sleeve can be arranged between the first guide groove 410 and the first guide rail, and a lubricating sleeve can be arranged between the second guide groove 510 and the second guide rail, so that the back plate of the injection platform can slide smoothly. In the present embodiment, the lubricating sleeves as described above are mounted on both ends of the first guide groove 410 and the second guide groove 510 in their respective extending directions.
In this embodiment, as shown in fig. 1 and 2, an end edge of a surface of the first guide sleeve 400 facing the first ear portion and an end edge of a surface of the second guide sleeve 500 facing the second ear portion may be respectively formed in rounded corners to further reduce the weight of the back plate of the shooter. In addition, a plurality of first reinforcing protrusions 430 may be formed at both ends of the rounded portion of the first guide sleeve 400 in the extending direction of the first guide sleeve 400, and a plurality of second reinforcing protrusions 530 may be formed at both ends of the rounded portion of the second guide sleeve 500 in the extending direction of the second guide sleeve 500, so as to increase the rigidity of the first guide sleeve 400 and the second guide sleeve 500 and prevent both from being deformed during sliding.
Further, in the present embodiment, as shown in fig. 1 and 2, both wall portions of the first guide bush 400 forming the first guide groove 410 may be formed with hole portions 600 communicating with the first guide groove 410; both wall portions of the second guide sleeve 500 forming the second guide groove may be formed with hole portions 600 communicating with the second guide groove 510 to further reduce the overall weight of the shooter rear plate.
However, not limited thereto:
first, although the hole portions 600 respectively provided on the first guide bush 400 and the second guide bush 500 in the present embodiment communicate with the first guide groove 410 and the second guide groove 510, respectively, both wall portions of the first guide bush 400 forming the first guide groove 410 may be formed with a recessed portion recessed toward the first guide groove 410, and both wall portions of the second guide bush 500 forming the second guide groove may be formed with a recessed portion recessed toward the second guide groove 510; secondly, based on the first, in the present embodiment, the size, shape, and number of the concave portions or the hole portions 600 are not limited, and a combination of the concave portions and the hole portions 600 may be provided on the same guide bush;
fourthly, as for the positions of the concave portion and the hole portion 600, as long as it is satisfied that the lubricating sleeve is not exposed or the fitting of the first guide groove 410 and the second guide groove 510 with the first guide rail and the second guide rail is not affected, it is preferable that the weight-reduced portions formed by the first guide groove 410 and the second guide groove 510 (i.e., the concave portion and the hole portion 600) may be symmetrical with respect to the central axis to prevent the difference in deformation amount due to the difference in the removed material position at both sides, thereby causing stress concentration and affecting the life of the stage back plate.
Fifthly, the injection platform back plate in this embodiment may further include a first reinforcing rib connecting the first ear portion 200 and the first guide sleeve 400 and a second reinforcing rib connecting the second ear portion 300 and the second guide sleeve 500, so as to increase the overall rigidity of the injection platform back plate to a certain extent.
The embodiment further provides an injection molding machine, which includes the injection table back plate and the injection table, and further includes a first guide rail and a second guide rail, and the installation manner of the injection table back plate installed on the injection molding machine is mentioned in the above description, and is not described herein again.
