[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the vertical injection molding machine upper and lower material feeding secondary positioning mechanism more clear and understandable, the vertical injection molding machine upper and lower material feeding secondary positioning mechanism will be further described in detail below in combination with the accompanying drawings and embodiments.
[0029] It should be noted that, in the embodiments of the vertical injection molding machine upper and lower material feeding secondary positioning mechanism, all directional indications (such as up, down, left, right, front, back, etc.) are used only to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the accompanying drawings), and if the specific posture changes, the directional indications will also change accordingly.
[0030] In addition, the description of "first", "second" and the like in the embodiments of the utility model is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.
[0031] The vertical injection molding machine feeding and discharging secondary positioning mechanism provided in the embodiment can position a workpiece twice after the workpiece is taken off from an injection mold, thereby ensuring that the workpiece can be accurately loaded onto a next processing position for subsequent processing and production.
[0032] Specifically, as shown in the drawings, the vertical injection molding machine feeding and discharging secondary positioning mechanism provided in the embodiment includes a positioning seat 100, a fixed part 200, a movable part 300, and a driving device 320. Figs. 1-3 The positioning seat 100 is used to support a workpiece to be positioned. The fixed part 200 is arranged side by side along a first predetermined direction and is provided with two parts for positioning the first predetermined direction. The movable part 300 is arranged side by side along a second predetermined direction and is provided with two parts for positioning the second predetermined direction. The two fixed parts 200 and the two movable parts 300 define a positioning area 101. The driving device 320 is arranged below the fixed part 200 and is in transmission connection with the two movable parts 300.
[0033] In the process of clamping and positioning the workpiece, the workpiece is placed in the positioning area 101 and is limited by the two fixed parts 200 in the first predetermined direction, which is the horizontal direction in this embodiment. At this time, the movable part 300 moves towards each other under the drive of the driving device 320, thereby clamping and positioning the workpiece in the second predetermined direction, which is the vertical direction in this embodiment. Through the clamping of the movable part 300 in the vertical direction, the workpiece is positioned in the horizontal and vertical directions, which can conveniently realize the positioning operation of the workpiece, thereby ensuring that the workpiece is in a determined position when it is grabbed again. Through the technical scheme provided in this embodiment, the workpiece can be quickly positioned, and the structure of the positioning mechanism is relatively simple, without the need to open a positioning slot. Moreover, it can adapt to different sizes of workpieces for positioning operation, and has higher practicality.
[0034] In this embodiment, in order to make the positioning seat 100 and the driving device 320 more convenient to install, an installation frame 304 is arranged below the positioning seat 100, and the driving device 320 is fixedly arranged on the installation frame 304. Meanwhile, two supports 110 are arranged on the positioning seat 100, and the two supports 110 are fixedly arranged at both ends of the positioning seat 100 and suspend the positioning seat 100 above the driving device 320. The positioning seat 100 is suspended by the supports 110, which can make the driving device 320 arranged below the positioning seat 100 through the installation frame 304, and the movable part 300 moves along the second predetermined direction to realize the clamping or loosening action.
[0035] In this embodiment, a positioning part 102 is arranged on the positioning seat 100, the positioning part 102 protrudes upwards, and a curved surface 104 with one end high and the other end low is arranged along the first predetermined direction. The two fixed parts 200 are arranged at the high end and the low end of the curved surface 104, and the movable part 300 is located above the curved surface 104 and reciprocates along the second predetermined direction.
[0036] In the process of positioning, the bottom of the positioning area 101 defined by the movable part 300 and the fixed part 200 is a curved surface with a high end and a low end. When the workpiece is placed in the positioning area 101, it can slide along the curved surface 104 towards the low end, so that one end of the workpiece abuts against the fixed part 200 at the low end of the positioning area 101. At this time, the movable part 300 clamps the workpiece in the second predetermined direction, thereby ensuring more accurate positioning of the workpiece. It is worth noting that the positioning area 101 is arranged as a curved surface 104 instead of a simple inclined surface, in order to avoid the workpiece moving quickly in the positioning area 101, thereby affecting the stability of the workpiece when placed in the positioning area 101.
[0037] In this embodiment, the movable component 300 includes a base 301 and a rod 302. The base 301 includes two rods arranged side by side along a second predetermined direction and connected to the driving device 320 respectively. The driving device 320 drives the rods to move back and forth in opposite directions along the second predetermined direction. The two rods are fixedly mounted on the base 301 and extend upward. The positioning seat 100 is provided with a limiting groove 103 for the rods to extend out and be limited in its movement.
[0038] The above technical solution enables the drive device 320 and the base to be positioned below the positioning seat 100, and avoids the need to set a sliding connection structure between the rod 302 or the base 301 and the positioning seat 100. Therefore, it can reduce the production process and cost, but does not affect the positioning accuracy.
[0039] In this embodiment, the driving device 320 is a finger cylinder, and the two bases are respectively connected to the two fingers of the finger cylinder.
[0040] During the installation of rod 302 and base 301, in order to facilitate the adjustment of the position of rod 302, such as... Fig. 2 As shown, the rod body has an elliptical cross-section mounting hole 303 along its axial direction, and a mounting groove extending in a second predetermined direction is provided at the bottom of the mounting hole. The fastener tube passes through the mounting groove to connect the rod body to the base 301. That is to say, the fastener can move within the mounting groove, thereby adjusting the position of the rod 302, so as to facilitate the adjustment of the distance between the two rods 302, thus enabling more adaptation to different workpiece positioning operations.
[0041] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
