Description

Technical Field

[0001] This utility model relates to the field of demolding technology, and in particular to a device for measuring the demolding force of a demolding agent. Background Technology

[0002] The device for measuring the release force of a release agent is usually called a release force tester or release force measuring device. It is a device specifically used to quantitatively measure the release resistance (i.e., release force) generated by the release agent during the molding process (such as injection molding, die casting, composite material molding, etc.).

[0003] In existing technologies, testing the release force of release agents typically requires placing the release device under test (e.g., a mold and molded part coated with release agent) on a test bench, using a traction device to perform release and measure the required force value. However, existing testing equipment often has only one fixed testing station. After completing one test, the operator needs to wait for the current test to finish completely, remove the tested device, and then install the next device under test. This process leads to interruptions in the testing process and waiting time, resulting in low overall testing efficiency. Therefore, it is necessary to design a release force measuring device that can improve the continuity and efficiency of testing. Utility Model Content

[0004] Therefore, it is necessary to provide a mold release force measuring device for mold release agents to address the aforementioned technical problems. By setting up a rotatable first and second test platform, along with an angle adjustment unit, rapid switching of the testing station is achieved. While the device on the first test platform is undergoing mold release force testing, the operator can simultaneously install and prepare the next device to be tested on the second test platform. After the first test platform completes its test, the second test platform can be quickly rotated to the working position for the next round of testing, thereby reducing equipment waiting and idle time and greatly improving overall testing efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A mold release force measuring device for a mold release agent includes a test position and a test frame fixed on the test position. The test frame is provided with a traction mold release unit inside, and a support platform fixed to the surface of the test position is provided below the traction mold release unit.

[0007] Guide rails are fixed on both sides of the top of the support platform, and a connecting plate is connected between the two guide rails. A first test platform is slidably assembled below the connecting plate. A connecting seat is fixed at one end of one side of the first test platform. A connecting block is hinged in the connecting seat, and a second test platform is fixed on the surface of the connecting block.

[0008] An angle adjustment unit is provided between the first test stand and the second test stand.

[0009] Furthermore, the angle adjustment unit includes a guide ring fixed inside the second test platform and an arc-shaped ring slidably disposed inside the guide ring, with one end of the arc-shaped ring extending outward and connected and fixed to the side of the first test platform.

[0010] Furthermore, an adjusting bolt is threadedly connected to the top of the guide ring, and one end of the adjusting bolt abuts against the surface of the arc-shaped ring.

[0011] Furthermore, the second test platform and the first test platform have the same length, width, and height.

[0012] Furthermore, sliding blocks are slidably provided at both ends of the guide rail near the adjusting bolt, and a positioning block is fixed at one end of the sliding block, with a positioning bolt threaded onto the surface of the positioning block.

[0013] Furthermore, a spring is connected to the other end of the sliding block, and one end of the spring is fixedly connected to the side wall of the guide rail.

[0014] Furthermore, the traction demolding unit includes a traction plate slidably disposed inside the test frame, a tension sensor connected to the bottom of the traction plate, and a traction ring connected to the end of the tension sensor.

[0015] Furthermore, an electric telescopic rod is fixed to the top of the test frame, and the output end of the electric telescopic rod is connected to the surface of the traction plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The mold release force measuring device for mold release agents provided by this utility model achieves rapid switching of testing positions by setting up a rotatable first test platform and a second test platform, in conjunction with an angle adjustment unit. While the device on the first test platform is undergoing mold release force testing, the operator can simultaneously install and prepare the next device to be tested on the second test platform. After the first test platform completes its test, the second test platform can be quickly rotated to the working position for the next round of testing, thereby reducing equipment waiting and idle time and greatly improving overall testing efficiency.

[0018] The guide rails, sliding blocks, and spring structure designed in the device facilitate the overall movement and positioning of the test platform. The angle adjustment unit, through the cooperation of guide rings, arc rings, and adjusting bolts, can adjust and reliably lock the angle of the second test platform relative to the first test platform, making the station switching process smooth and accurate, and adaptable to the needs of different operating spaces.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] Example 1

[0034] Please refer to Figures 1-6 As shown, a mold release force measuring device for a mold release agent includes a test position 1 and a test frame 2 fixed on the test position 1. The test frame 2 is provided with a traction mold release unit 5 inside, and a support platform 3 fixed to the surface of the test position 1 is provided below the traction mold release unit 5.

[0035] The support platform 3 has guide rails 31 fixed on both sides of its top. A connecting plate 32 is connected between the two guide rails 31. A first test platform 33 is slidably assembled below the connecting plate 32. A connecting seat 34 is fixed to one end of one side of the first test platform 33. A connecting block 35 is hinged inside the connecting seat 34. A second test platform 36 is fixed to the surface of the connecting block 35.

[0036] An angle adjustment unit 4 is provided between the first test platform 33 and the second test platform 36.

[0037] Because the release force measuring device for the release agent of this utility model has the above structure, it includes a first test platform 33 and a second test platform 36 that can move and rotate relative to each other along the guide rail 31. When the first test platform 33 is in the measuring position, the second test platform 36 can be rotated to the outside of the equipment through the hinge structure of the connecting seat 34 and the connecting block 35 to form a preparatory position. This allows the operator to complete the clamping preparation work of another position within one testing cycle, realizing the parallel operation of "test-preparation" and laying a structural foundation for subsequent rapid position switching and improved testing efficiency.

[0038] Meanwhile, once the first test bench 33 has completed its test, the clamping of the device to be tested on the second test bench 36 has also been completed. Therefore, the first test bench 33 can be pushed outwards, and the second test bench 36 can be moved to the inside of the guide rail 31 to form a test state, thus not affecting the disassembly of the demolding device on the first test bench 33 after the test is completed.

[0039] Example 2

[0040] The release force measuring device for the release agent provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, the angle adjustment unit 4 includes a guide ring 41 fixed in the second test platform 36 and an arc ring 42 slidably disposed in the guide ring 41. One end of the arc ring 42 extends outward and is connected and fixed to the side of the first test platform 33.

[0041] The top of the guide ring 41 is threaded with an adjusting bolt 43, one end of which abuts against the surface of the arc-shaped ring 42.

[0042] The second test platform 36 and the first test platform 33 have the same length, width and height.

[0043] Because the release force measuring device for the release agent of this utility model has the above structure, the design of the angle adjustment unit 4 allows for precise control and stable locking of the rotation angle of the second test platform 36 relative to the first test platform 33. Specifically, by tightening the adjusting bolt 43 so that its end abuts against the surface of the arc-shaped ring 42, sufficient friction can be generated within the guide ring 41, thereby fixing the second test platform 36 at any angle after its rotation and unfolding, facilitating clamping operations by the operator at the preparatory station. Simultaneously, the first and second test platforms are of the same size, ensuring consistency of testing conditions and ease of station interchangeability.

[0044] Example 3

[0045] The release force measuring device for the release agent provided in Example 1 or 2 is further optimized, such as... Figure 6 As shown, sliding blocks 310 are slidably provided at both ends of the guide rail 31 near the adjusting bolt 43. A positioning block 311 is fixed at one end of the sliding block 310, and a positioning bolt 312 is threadedly connected to the surface of the positioning block 311.

[0046] The other end of the sliding block 310 is connected to a spring 313, and one end of the spring 313 is fixedly connected to the side wall of the guide rail 31.

[0047] Because the release force measuring device for the release agent of this utility model has the above structure, the sliding block 310, spring 313 and positioning block 311 set at both ends of the guide rail 31 constitute an elastic positioning mechanism. For example, when the first test platform 33 is subjected to traction test, the positioning block 311 can be pushed to slide towards the first test platform 33, so that the second test platform 36 can be rotated smoothly without forming a relative motion resistance. At the same time, the rotating positioning bolt 312 achieves the positioning function of the second test platform 36 when the second test platform 36 is in a parallel state with respect to the first test platform 33 (without rotation).

[0048] Example 4

[0049] The release force measuring device for the release agent provided in Example 3 has been further optimized, such as... Figure 1 As shown, the traction demolding unit 5 includes a traction plate 51 slidably disposed inside the test frame 2, a tension sensor 52 connected to the bottom of the traction plate 51, and a traction ring 53 connected to the end of the tension sensor 52.

[0050] The top of the test frame 2 is fixed with an electric telescopic rod 54, and the output end of the electric telescopic rod 54 is connected to the surface of the traction plate 51.

[0051] Because the release force measuring device of this invention has the above structure, the electric telescopic rod 54 serves as the power source, driving the traction plate 51 and the tension sensor 52 and traction ring 53 connected thereto to move vertically to simulate the demolding action. The tension sensor can measure the force value required during the demolding process in real time and accurately, and output the data. Combined with a dual-station test stand that can be quickly switched, the entire device achieves efficient and continuous operation from sample preparation, positioning, demolding, measurement to data acquisition.

[0052] like Figure 1 At this time, the first test platform 33 is located below the traction demolding unit 5. The demolding device to be tested can be installed on the first test platform 33, and then connected to the upper traction ring 53. The demolding force can be detected by the data of the tension sensor 52 through the electric telescopic rod 54 for traction.

[0053] During this process, the demolding force device to be tested can be installed on the second test bench 36 located on the outside. During installation, the positioning block 311 near the second test bench 36 can be pushed to slide towards the first test bench 33. This allows the second test bench 36 to rotate along the position of the connecting seat 34 without creating relative movement resistance. After rotation, the adjusting bolt 43 can be rotated to position the arc ring 42. This allows the second test bench 36 to be moved to one side for better installation of the next testing device.

[0054] After the test on the first test bench 33 is completed, the installation operation on the second test bench 36 is also finished. Now, press the positioning block 311 again, then rotate the second test bench 36 to reset it so that it is parallel to the first test bench 33. Then release the positioning block 311 and push the second test bench 36 to move it below the traction demolding unit 5, causing the first test bench 33 to move externally and ultimately form the desired shape. Figure 2 The state shown;

[0055] In this state, the positioning block 311 near the first test stage 33 can be pushed to rotate the first test stage 33 and adjust its angle (e.g., ...). Figure 3 As shown in the figure, this facilitates the disassembly of the demolding device after the previous test is completed, thus improving the overall operating efficiency. In practical applications, the surfaces of the first test platform 33 and the second test platform 36 can be equipped with multiple mounting brackets or mounting bolt holes (not shown in the figure), and the surface of the connecting plate 32 can also be equipped with bolts (not shown in the figure) for testing and positioning of the first test platform 33 and the second test platform 36.
