Technical Field
[0001] The utility model relates to the field of injection molded part detection equipment, and particularly relates to a thrust detection fixture for an injection molded base. Background Art
[0002] An injection molded base is a plastic base product obtained by injection molding. The injection molded base includes an outer seat body and an inner seat body. The convex block on the inner seat body passes through the end face of the outer seat body and is exposed outside. After the processing and assembly are completed, it is necessary to detect the structural strength of the convex block part exposed on the inner seat body.
[0003] When the existing injection molded base is being detected, the injection molded base is placed in a positioning groove, and the convex block on the inner seat body is pushed by a cylinder for detection. The detection accuracy is relatively low. There are various specifications of injection molded bases, and the positions of the convex blocks on the inner seat bodies of different specifications of injection molded bases are not the same. It is difficult for the existing detection equipment to adapt to the thrust tests of different specifications of injection molded bases. Therefore, a thrust detection fixture for an injection molded base is needed. Summary of the Utility Model

Sector-shaped positioning seats and arc-shaped positioning seats are arranged at intervals on the bottom plate. Clamping cylinders are arranged on both sides of the sector-shaped positioning seats and arc-shaped positioning seats on the bottom plate. A clamping block is fixedly connected to the sliding table of each clamping cylinder. A pushing cylinder is arranged beside the arc-shaped positioning seat on the bottom plate. A lead screw and an adjusting seat are arranged on the sliding table of the pushing cylinder. The lead screw is rotationally connected to the sliding table of the pushing cylinder. The adjusting seat is slidably connected to the sliding table of the pushing cylinder. The adjusting seat is threadedly connected to the lead screw. A push plate is detachably connected to the adjusting seat.
[0006] Further, the sector-shaped positioning seats, arc-shaped positioning seats and clamping cylinders are all fixedly connected to the bottom plate. Auxiliary positioning rods are fixedly connected to the bottom plate at the sector-shaped positioning seats and arc-shaped positioning seats.
[0007] Further, a relief groove is opened on each clamping block. The relief groove is arranged corresponding to the sector-shaped positioning seat. A C-shaped groove is arranged in the middle of the clamping block.
[0008] Further, a clamping groove is opened on the adjusting seat. A magnet is fixedly connected in the clamping groove. A convex block corresponding to the clamping groove is arranged on the push plate. A profiling groove is arranged on the other side of the push plate.

[0014] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0015] Refer to Figures 1 - 3 A thrust detection fixture for an injection molding base shown in the figure, including a bottom plate 1. A sector-shaped positioning seat 2 and an arc-shaped positioning seat 3 are arranged at intervals on the bottom plate 1. Clamping cylinders 4 are arranged on both sides of the sector-shaped positioning seat 2 and the arc-shaped positioning seat 3 on the bottom plate 1. A clamping block 401 is fixedly connected to the sliding table of each clamping cylinder 4. A pushing cylinder 5 is arranged beside the arc-shaped positioning seat 3 on the bottom plate 1. A lead screw 501 and an adjusting seat 502 are arranged on the sliding table of the pushing cylinder 5. The lead screw 501 is rotatably connected to the sliding table of the pushing cylinder 5, and the rotation of the lead screw 501 can drive the adjusting seat 502 to slide and adjust along the sliding table of the pushing cylinder 5. The adjusting seat 502 is slidably connected to the sliding table of the pushing cylinder 5. The adjusting seat 502 is threadedly connected to the lead screw 501. A pushing plate 503 is detachably connected to the adjusting seat 502.
[0016] The sector positioning seat 2, the arc-shaped positioning seat 3 and the clamping cylinder 4 are all fixedly connected to the bottom plate 1. The clamping cylinder 4 is used to drive the clamping block 401 to clamp the injection molding base. An auxiliary positioning rod 6 is fixedly connected to the bottom plate 1 at the sector positioning seat 2 and the arc-shaped positioning seat 3. The auxiliary positioning rod 6 can further limit the placement of the injection molding base.
[0017] A relief groove is formed in each clamping block 401. The relief groove is arranged corresponding to the sector positioning seat 2. The relief groove gives way to the sector positioning seat 2 during the clamping process to prevent interference. A C-shaped groove is provided in the middle of the clamping block 401.
[0018] A clamping groove is formed in the adjusting seat 502. A magnet is fixedly connected in the clamping groove. The magnet can adsorb and fix the push plate 503. A convex block corresponding to the clamping groove is provided on the push plate 503. A profiling groove is provided on the other side of the push plate 503. The provision of the profiling groove can ensure that the push plate 503 completely fits the convex block part on the injection molding base, thereby improving the detection accuracy.
[0019] The working principle of the present utility model is as follows: When the present utility model is in use, the adjusting seat 502 is slidably adjusted along the sliding table of the pushing cylinder 5 by rotating the lead screw 501 to ensure that the push plate 503 corresponds to the convex block on the injection molding base. The corresponding push plate 503 can be selected according to the shape of the convex block and installed in the clamping groove of the adjusting seat 502. The push plate 503 is adsorbed and fixed by the magnet (when the pushing test is carried out, the push plate 503 is always adsorbed and fixed in the clamping groove of the adjusting seat 502). During the test, the injection molding base is placed on the bottom plate 1 along the sector positioning seat 2, the arc-shaped positioning seat 3 and the auxiliary positioning rod 6. Then, the clamping cylinder 4 drives the clamping block 401 to clamp the injection molding base. Finally, the pushing cylinder 5 drives the push plate 503 to slide towards the convex block of the injection molding base. If the convex block part does not break during the pushing process of the pushing cylinder 5, the thrust test is qualified; otherwise, it is a defective product.
[0020] The above embodiments are used to further illustrate the present utility model, but do not limit the present utility model to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be understood to be within the protection scope of the present utility model.
