Description

Technical Field

[0001] The utility model relates to the technical field of sample making moulds, in particular to a sample making mould for detecting plastic pipes. Background Art

[0002] Before testing the tensile properties of plastic pipes, dumbbell-shaped specimens are prepared. Milling is currently the primary method for preparing dumbbell specimens. Milling involves cutting the plastic pipe into sheets. The sheet is then clamped in a dumbbell-shaped specimen fixture. The fixture is then fed into a milling cutter. During this process, the worker presses the fixture against the milling cutter, milling the specimen into a shape that matches the contours of the fixture.

[0003] According to a publicly disclosed sample making machine for testing plastic pipes (Announcement No.: CN216012891U), the above application is provided with a moving block, a placement seat, a reset member, a transverse drive mechanism and a longitudinal drive mechanism, so that the sample fixed on the placement seat is adjusted to a positional relationship with the milling cutter by the longitudinal drive mechanism, and then the sample is driven to feed the milling cutter transversely by the transverse drive mechanism. The reset member can ensure that the sample is always in contact with the milling cutter during transverse feeding, so that the sample is milled into a shape consistent with the contour of the sample fixture, thereby improving work efficiency and the safety of the sample making process.

[0004] However, during the actual use of the above-mentioned equipment, when the sample is placed on the sample making machine for cutting, the four sides of the sample cannot be completely cut, and the position of the sample on the mold needs to be manually moved, which reduces the efficiency of sample making. In view of this, we propose a plastic pipe inspection sample making mold. Utility Model Content

The outer wall of the rotating shaft is rotatably connected to a push rod, and one end of the push rod close to the rotating shaft is fixedly connected to the fixing plate. The outer wall of the push rod is slidably connected to a locking block, and the outer wall of the limiting plate is provided with a locking groove.

[0010] Preferably, the upper outer wall of the base plate is fixedly connected to the lower outer wall of the lower mold, and the lower outer wall of the base plate is provided with a friction pad, so that the mold can be placed more stably on the upper outer wall of the base.

[0011] Preferably, the lower mold is the same size as the upper mold, and the lower mold fits the upper mold so that when the pipe in the middle of the mold is cut, the pipe can be cut into the required shape along the edge of the mold.

[0012] Preferably, the size of the locking block is consistent with that of the locking slot, and a spring is provided at the connection between the locking block and the push rod. When the fixing plate rotates to be parallel to the base, the locking block moves in the locking slot.

At this time, the upper and lower molds can be fixed by bolts at both ends, making the sample more stable during cutting, so that the efficiency of sample making is further improved.

[0017] 2. The plastic pipe inspection sample preparation mold can change the position of the mold by pushing the push rod, so that the mold can grind off excess samples through the grinding rod from different angles. When the push rod is rotated to make the fixed plate parallel to the base, the mold is lifted by the fixed plate, making it easier to fall off the mold sample, thereby improving the mold sample preparation efficiency.

The lower end of the bolt 55 is threadedly connected to the base plate 56. The outer wall of the cutting plate 51 is fixedly connected to the limiting plate 57. The outer wall of the base plate 56 is provided with a limiting groove 58. The limiting plate 57 is slidably connected to the inner wall of the limiting groove 58.

[0026] In one embodiment of the present utility model, a fixing assembly 6 is provided on the outer wall of the limiting plate 57, and the fixing assembly 6 includes a rotating shaft 61, which is fixedly connected to the outer wall of the limiting plate 57. The outer wall of the rotating shaft 61 is rotatably connected to a push rod 62, and one end of the push rod 62 close to the rotating shaft 61 is fixedly connected to a fixing plate 63, and the outer wall of the push rod 62 is slidably connected to a locking block 64, and the outer wall of the limiting plate 57 is provided with a locking groove 65.

[0027] In addition, the upper outer wall of the bottom plate 56 is fixedly connected to the lower outer wall of the lower mold 3, and the lower outer wall of the bottom plate 56 is provided with a friction pad, so that the mold can be placed more stably on the upper outer wall of the base 1, and the mold is not easy to shake when the grinding rod 2 is used to make the sample.

[0028] In an embodiment of the present invention, the lower mold 3 and the upper mold 4 are of the same size, and the lower mold 3 and the upper mold 4 fit together, so that when the pipe in the middle of the mold is cut, the pipe can be cut into the required shape along the edge of the mold to complete the sample making.

[0029] In the embodiment of the present utility model, the size of the locking block 64 is consistent with the size of the locking groove 65. A spring is provided at the connection between the locking block 64 and the push rod 62. When the fixing plate 63 rotates to be parallel to the base 1, the locking block 64 moves in the locking groove 65, so that the locking block 64 clamps the locking groove 65, prompting the push rod 62 to be fixed.

[0030] In an embodiment of the present invention, the slide groove 52 and the cutting groove 54 are located on the same vertical line, and the inner wall of the end of the cutting groove 54 away from the bolt 55 is flush with the inner wall of the end of the slide groove 52 away from the bolt 55.

The width and shape of the sample can be cut without changing the direction of the sample in the mold, which makes the sample making efficiency of the mold higher. At this time, the upper mold 4 and the lower mold 3 can be fixed by the bolts 55 at both ends, so that the sample is more stable during cutting. The limit plate 57 and the limit groove 58 make the upper mold 4 and the lower mold 3 easier to align, so that the efficiency of sample making is further improved.

When the push rod 62 is rotated to make the fixed plate 63 parallel to the base 1, the mold is lifted by the fixed plate 63, so that the mold sample is easier to fall off, thereby making the sample making efficiency of the mold higher.

[0033] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention.
