Description

Technical Field

[0001] This utility model relates to the field of sponge tensile test specimen preparation technology, specifically a sponge tensile test specimen mold. Background Technology

[0002] In the process of sponge formulation and production, in order to inspect the quality of the sponge in a timely manner, it is necessary to take samples from the whole sponge and test them to check whether its various properties meet the requirements of production and use. Among them, the tensile test is an important step in determining the mechanical properties of sponge materials under uniaxial tensile load.

[0003] Current tensile tests typically involve cutting and sampling at the edge of the sponge. This not only results in variations in the size and length of the cuts, but also often leads to inaccurate measurement data.

[0004] To address the aforementioned issues, we have made improvements and proposed a sponge tensile test specimen mold. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a sponge tensile test specimen mold, including a support plate and a handle, with a sleeve connected to the lower part of the support plate;

[0007] The sleeve is configured as four;

[0008] The bottom of the sleeve is connected to a support rod, and a pressure strip is provided between two oppositely installed support rods. An anti-slip strip is provided at the bottom of the pressure strip.

[0009] The surface of the support plate is provided with several evenly distributed through slots, the bottom of which is connected to a mounting bracket, and a blade is sleeved on the outside of the mounting bracket.

[0010] The mounting bracket has mounting slots at both ends;

[0011] The blade has through holes at both ends.

[0012] As a preferred embodiment of this utility model, the bottom of the sleeve is provided with a bottom cavity, a spring is connected to the inner top surface of the bottom cavity, a sliding rod is slidably connected inside the bottom cavity, and the bottom of the spring is connected to the top of the sliding rod.

[0013] In a preferred embodiment of this invention, the top of the support rod is connected to the bottom of the sliding rod.

[0014] As a preferred embodiment of this utility model, the anti-slip strip is made of rubber and is arranged in a Z-shaped extension.

[0015] As a preferred embodiment of this utility model, the through hole is internally threaded with a fixing bolt, and the fixing bolt passes through the mounting groove and is slidably connected to the mounting groove.

[0016] In a preferred embodiment of this utility model, the handle is located on the upper part of the support plate, and the handle is fixedly connected to the support plate by bolts.

[0017] As a preferred embodiment of this utility model, the length of the sleeve is consistent with the height of the mounting bracket.

[0018] The beneficial effects of this utility model are:

[0019] 1. This type of sponge tensile test specimen mold is pressed into the middle of the sponge by pressing down the handle and the support plate. During this process, the pressure strip contacts the upper part of the sponge. The Z-shaped extended anti-slip strip can increase the friction between the pressure strip and the sponge, and prevent the mold from moving during the sampling process, so as to maintain the consistency of the specimen size.

[0020] 2. During the pressing process, the support rod drives the slide rod to slide into the bottom cavity. At this time, the spring is compressed, and the bottom of the blade contacts the sponge. When the pressure is continued until the slide rod extends into the top of the bottom cavity, the blade completes the cutting of the sponge. When the pressure is removed, the blade falls naturally along the mounting groove. When the mold is taken out, the sponge sample is taken out of the sponge block. The telescopic blade can prevent the user from being injured by accident during daily placement, thus improving the safety of the mold. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-4 As shown, a sponge tensile test specimen mold includes a support plate 1 and a handle 2, with a sleeve 3 connected to the lower part of the support plate 1.

[0029] Sleeve 3 is set to four;

[0030] The bottom of the sleeve 3 is connected to a support rod 7, and a pressure strip 4 is provided between the two support rods 7 installed opposite each other. An anti-slip strip 6 is provided at the bottom of the pressure strip 4.

[0031] The surface of the support plate 1 is provided with several evenly distributed through grooves 5, the bottom of the through grooves 5 is connected to the mounting bracket 8, and the mounting bracket 8 is fitted with a blade 9.

[0032] Mounting slots 14 are provided at both ends of the mounting bracket 8;

[0033] Through holes 15 are provided at both ends of the blade 9.

[0034] The bottom of the sleeve 3 has a bottom cavity 12, and a spring 13 is connected to the inner top surface of the bottom cavity 12. A slide rod 11 is slidably connected inside the bottom cavity 12, and the bottom of the spring 13 is connected to the top of the slide rod 11.

[0035] The top of the support rod 7 is connected to the bottom of the slide rod 11.

[0036] The anti-slip strip 6 is made of rubber and has a Z-shaped extension.

[0037] The through hole 15 is internally threaded with a fixing bolt 10. The fixing bolt 10 passes through the mounting groove 14 and is slidably connected to the mounting groove 14. The fixing bolt 10 can be removed to replace the blade 9, thus avoiding the blade 9 becoming dull and difficult to cut due to long-term use.

[0038] The handle 2 is located on the upper part of the support plate 1, and the handle 2 is fixedly connected to the support plate 1 by bolts.

[0039] The length of sleeve 3 is the same as the height of mounting bracket 8.

[0040] Working principle: In use, this sponge tensile test specimen mold is pressed into the middle of the sponge by pressing down the handle 2 and the support plate 1. During this process, the pressure strip 4 contacts the upper part of the sponge, and the Z-shaped extended anti-slip strip 6 can increase the friction between the pressure strip 4 and the sponge, preventing the mold from moving during sampling and maintaining the consistency of the specimen size. During the pressing process, the support rod 7 drives the slide rod 11 to slide into the bottom cavity 12. At this time, the spring 13 is compressed, and the bottom of the blade 9 contacts the sponge. When the pressure is continued until the slide rod 11 extends into the top of the bottom cavity 12, the blade 9 completes the cutting of the sponge. When the pressure is released, the blade 9 falls naturally along the mounting groove. When the mold is removed, the sponge specimen is taken out of the sponge block. The telescopic blade 9 can prevent the user from being injured by accidental contact during daily storage, thus improving the safety of the mold.
