[0002] Engineering plastics are a class of plastic materials with high mechanical strength, heat resistance, chemical corrosion resistance, and other excellent physical properties. They are widely used in the automotive, electronics, aerospace, construction, and medical device industries.

[0003] In practical applications of engineering plastics, flowability is an extremely critical property. Flowability directly affects the filling capacity of the plastic during the molding process and the quality of the final product. Good flowability means that the plastic can fill every corner of the mold more evenly during injection molding or compression molding, thereby reducing defects such as bubbles and shrinkage cavities, and ensuring a smooth and flawless surface of the finished product. Therefore, testing the flowability of engineering plastics is particularly important to ensure product quality and optimize production processes.

[0004] However, in traditional testing methods, plastic samples typically need to be manually removed after testing. This process is arduous for operators, especially when multiple tests need to be performed quickly and consecutively; manually removing each plastic sample significantly increases the workload. Manual operation is not only time-consuming but also inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a quick-installation and quick-disassembly engineering plastic flow test mold. By using this device, the problem of long time and low efficiency in manually removing plastic samples after testing is solved in the existing technology.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a quick-assembly and quick-disassembly engineering plastic flow test mold, including a lower mold body and an upper mold body disposed above the lower mold body. The top of the lower mold body is provided with a groove, and a middle mold body is disposed inside the groove. The top of the middle mold body is provided with a test groove, and a cavity is provided inside the middle mold body. A lifting component is disposed inside the cavity.

[0007] The lifting assembly includes a motor installed at the bottom of the cavity, a threaded rod fixedly connected to the output end of the motor, a sleeve rod threadedly connected to the outer surface of the threaded rod, a fixing plate fixedly connected to the top of the sleeve rod, and a top rod fixedly connected to the top of the fixing plate. The bottom of the inner wall of the test slot has an opening with the diameter of the opening equal to the diameter of the top rod. The opening, the test slot, and the cavity are all connected.

[0008] Furthermore, a groove is provided on the inner wall of the cavity, and a slider is fixedly connected to one side of the fixed plate, with the slider slidably connected to the groove.

[0009] Furthermore, a cooling box is fixedly connected inside the groove. A first air inlet is opened on one side of the cooling box, and a second air inlet is opened on one side of the lower mold body. The first air inlet and the second air inlet are connected to each other, and the second air inlet is connected to an external cold source device.

[0010] Furthermore, a first exhaust port is provided on the outer surface of the cooling box, a connecting plate is provided on one side of the middle mold body, and a second exhaust port is provided on the outer surface of the connecting plate. The first exhaust port, the second exhaust port, the groove and the cavity are all connected.

[0011] Furthermore, a positioning plate is fixedly connected to one side of the middle mold body, and a positioning groove is opened at the top of the lower mold body. The positioning groove is connected to the groove, and the positioning plate is set in correspondence with the positioning groove.

[0012] Furthermore, a first threaded hole is provided on the outer surface of the positioning plate, and a second threaded hole is provided at the top of the positioning groove. A locking bolt is threadedly connected between the first threaded hole and the second threaded hole.

[0013] Compared with the prior art, the beneficial effects of this utility model include: the motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the sleeve rod connected to its outer surface to move upward, thereby driving the fixed plate and the push rod to move upward.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] According to one embodiment of the present invention, in conjunction with Figures 1-6 The diagram shows a quick-assembly and quick-disassembly engineering plastic flow test mold, including a lower mold body 1 and an upper mold body 2 disposed above the lower mold body 1. The top of the lower mold body 1 has a groove 11, and a middle mold body 3 is disposed inside the groove 11. The top of the middle mold body 3 has a test groove 32, and a cavity 33 is disposed inside the middle mold body 3. A lifting component 5 is disposed inside the cavity 33.

[0024] In this embodiment, the lifting assembly 5 includes a motor 51 installed at the bottom of the cavity 33, a threaded rod 52 fixedly connected to the output end of the motor 51, a sleeve rod 53 threadedly connected to the outer surface of the threaded rod 52, a fixing plate 54 fixedly connected to the top end of the sleeve rod 53, and a top rod 55 fixedly connected to the top end of the fixing plate 54. The bottom end of the inner wall of the test groove 32 is provided with a through-hole 321, the diameter of the through-hole 321 is equal to the diameter of the top rod 55, and the through-hole 321, the test groove 32 and the cavity 33 are all connected. In the initial state, the push rod 55 is located inside the opening 321. At this time, the highest point of the push rod 55 and the highest point of the opening 321 are at the same horizontal line. The plastic is placed in the test tank 32 and solidified. The operator observes the solidified plastic to judge its fluidity. The motor 51 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the sleeve 53, which is threaded to its outer surface, to move upward, thereby driving the fixed plate 54 and the push rod 55 to move upward. The push rod 55 moves upward and extends out of the opening 321, making it easier to push out the solidified plastic inside the test tank 32. This reduces the time for manually removing the sample and ensures the convenience of preparation and completion of each experiment, which is conducive to conducting multiple tests continuously.

[0025] A groove 331 is provided on the inner wall of the cavity 33. A slider 541 is fixedly connected to one side of the fixed plate 54, and the slider 541 is slidably connected to the groove 331. When the threaded rod 52 rotates, it drives the fixed plate 54 and the push rod 55 to move upward. The slider 541 moves upward along the groove 331, which plays a guiding role and prevents the sleeve rod 53 from rotating, making the entire lifting process more stable and ensuring the linearity of the push rod 55's movement.

[0026] A cooling box 6 is fixedly connected inside the groove 11. A first air inlet is located on one side of the cooling box 6, and a second air inlet 12 is located on one side of the lower mold body 1. The first air inlet and the second air inlet 12 are connected, and the second air inlet 12 is connected to an external cooling source device. The external cooling source device provides cooling gas at a certain pressure. The cooling box 6 is made of a metal material with good heat transfer properties to significantly improve cooling efficiency; stainless steel and alloy steel are preferred. By introducing cooling gas at a certain pressure into the cooling box 6, the solidification speed of the plastic sample is accelerated, which is faster and more efficient than traditional natural cooling methods, helping to shorten the experimental cycle and improve work efficiency.

[0027] The cooling box 6 has a first exhaust port 61 on its outer surface, and a connecting plate 31 is provided on one side of the central mold body 3. The connecting plate 31 has a second exhaust port 311 on its outer surface. The first exhaust port 61, the second exhaust port 311, the groove 11, and the cavity 33 are all connected. The cooling gas forms a flow path, flowing from the cooling box 6 through the first exhaust port 61 and the second exhaust port 311 and finally into the cavity 33, which facilitates the improvement of the cooling effect on the plastic inside the test tank 32.

[0028] A positioning plate 4 is fixedly connected to one side of the middle mold body 3, and a positioning groove 13 is opened at the top of the lower mold body 1. The positioning groove 13 is connected to the groove 11, and the positioning plate 4 is correspondingly set with the positioning groove 13. Through the precise cooperation of the positioning plate 4 and the positioning groove 13, it is easy to ensure that the middle mold body 3 is accurately placed in the same position each time, making the installation process of the middle mold body 3 simpler and faster.

[0029] The outer surface of the positioning plate 4 has a first threaded hole 41, and the top of the positioning groove 13 has a second threaded hole 131. A locking bolt 7 is threadedly connected between the first threaded hole 41 and the second threaded hole 131. The locking bolt 7 facilitates the fixing of the positioning plate 4 and the positioning groove 13, thereby facilitating the fixing of the middle mold 3 and the lower mold 1. When it is necessary to clean, maintain or replace the middle mold 3, simply loosen the locking bolt 7 to easily remove the middle mold 3, making it easy to clean any residual plastic materials or other impurities after the experiment.

[0030] In use, initially, the push rod 55 is located inside the opening 321, with the highest point of the push rod 55 and the highest point of the opening 321 at the same horizontal level. Plastic is placed in the test chamber 32 and solidifies. The operator observes the solidified plastic to determine its flowability. Cooling gas with a certain pressure is introduced into the cooling box 6, forming a flow path that passes from the cooling box 6 through the first exhaust port 61 and the second exhaust port 311, finally entering the cavity 33. This improves the cooling effect on the plastic inside the test chamber 32, accelerating the solidification speed of the plastic sample. This method is faster and more efficient than traditional natural cooling. This helps to shorten the experimental cycle and improve work efficiency. After the test is completed, the motor 51 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the sleeve rod 53, which is threaded to its outer surface, to move upward, thereby driving the fixed plate 54 and the push rod 55 to move upward. The push rod 55 moves upward and extends out of the through-hole 321, which makes it easy to push out the solidified plastic inside the test groove 32. This reduces the time for manually removing the sample and ensures the convenience of preparation and finishing work for each experiment. It is also conducive to conducting multiple tests continuously. Loosening the locking bolt 7 allows the middle mold 3 to be easily removed, making it easy to clean up any plastic materials or other impurities that may remain after the experiment.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
