Technical Field
[0001] The utility model relates to the technical field of measuring fixtures, in particular to a measuring fixture for injection molded parts. Background Art
[0002] Injection molded parts are plastic parts manufactured using the injection molding process, a process in which molten plastic material is injected into a mold and the desired shape and structure is formed after cooling and solidification. The three-dimensional coordinate measuring machine can measure the key dimensions of the injection mold, such as length, width, height, diameter, shape characteristics of the injection mold, surface quality, hole diameter and hole spacing. By comparing with the dimensions required by the design, the accuracy of the mold can be determined and whether there is dimensional deviation can be checked.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figure 1-Figure 5 As shown, the utility model proposes an injection molded part measuring fixture, including a fixed plate 1, a mounting frame 4, a mounting tube 6, a suction tube 7, a motor 12 and a push plate 16, a mounting frame 4 is arranged above the fixed plate 1, support rods 2 are arranged at the four corners of the lower end of the mounting frame 4, the lower end of the support rod 2 is connected to the upper end of the fixed plate 1, a placement groove 10 is opened inside the mounting frame 4, a collecting box 5 is arranged inside the placement groove 10, and limiting blocks 9 are arranged at both ends of the collecting box 5, a mounting tube 6 is arranged at the upper end of the mounting frame 4, a negative pressure pump 3 is arranged on one side of the mounting frame 4, and the suction end of the negative pressure pump 3 observes the mounting tube 6, and the upper end of the mounting tube 6 is provided with equidistantly distributed suction tubes 7, and a placement ring 8 is arranged on the outer wall of the upper end of the suction tube 7, and the placement ring 8 is at the same horizontal height as the upper end of the suction tube 7, and a pressure compensation valve 11 is arranged at one end of the mounting tube 6.
[0022] The implementation steps based on Example 1 are as follows: the fixing plate 1 is installed and placed on the workbench of the three-dimensional coordinate measuring machine, the injection molded part is placed on the suction tube 7, and the injection molded part is supported by the placement ring 8. The negative pressure pump 3 generates a suction force, and the suction force causes a negative pressure to be generated inside the mounting tube 6. The suction force is diverted through the suction tube 7, and the suction force acts on the injection molded part to fix the injection molded part and fix the injection molded part during the process. The three-dimensional coordinate measuring machine detects multiple injection molded parts at the same time. It is worth noting that only the flat position of the injection molded part can be sucked to avoid leakage of the suction force caused by the concave and convex parts of the injection molded part. When it is necessary to adsorb one side of the uneven injection molded part, a high-power negative pressure pump 3 is required, and the injection molded part avoids being clamped by the fixture, so it is easy to fix the injection molded part during inspection.
[0023] like Figure 1-Figure 5 As shown, compared with the first embodiment, the injection molded part measuring fixture proposed by the utility model further includes: a rotating block 17 is arranged inside the upper end of the suction tube 7, a push plate 16 is arranged on one side of the upper end of the rotating block 17, and an inclined surface 18 is arranged on the upper end of the push plate 16; a motor 12 is arranged on one side above the mounting tube 6, and a rotating shaft 13 is arranged at one end of the motor 12; sealing rings 15 are embedded and installed inside both ends of the suction tube 7, and the rotating shaft 13 is rotatably inserted in the sealing ring 15, the rotating shaft 13 passes through the rotating block 17 and is fixedly connected to the rotating block 17; a bearing bracket 14 is arranged on one side of the upper end of the mounting tube 6, and one end of the rotating shaft 13 is rotatably inserted in the bearing bracket 14.
[0024] In this embodiment, after the detection, the pressure-replenishing valve 11 is passed to supplement the internal pressure of the installation tube 6, and the suction tube 7 loses the suction fixation on the injection molded part. The motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the rotating block 17 to rotate inside the suction tube 7, driving the push plate 16 to rotate with the rotating shaft 13 as the axis. The push plate 16 lifts the injection molded part at the upper end, and the injection molded part slides to the lower part of the inclined surface 18 through the inclined surface 18. After the push plate 16 passes through the suction tube 7, the injection molded part after detection is pushed into the collection box 5, avoiding the injection molded part being clamped by the clamp, and the manual loosening of the clamp by the staff is cumbersome. The injection molded part after detection is automatically unloaded, thereby optimizing the injection molded part detection process.

Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
