Description

Technical Field

[0001] This utility model relates to the field of compression molding technology, and in particular to a high-efficiency device for discharging block compression molding materials. Background Technology

[0002] Compression molding, also known as compression molding, is a process where block plastic or rubber materials are heated and pressed into a finished product within a closed mold cavity. This plastic processing method typically involves placing powdered, granular, agglomerated, or flake-shaped preforms, or those similar in shape to the desired product, into a heated mold cavity, then closing the mold and applying pressure to shape and cure or vulcanize it. The finished product is then obtained through demolding. This process is particularly suitable for molding thermosetting plastics.

[0003] For example, Chinese utility model patent (CN219789026U) discloses a high-efficiency device for discharging block compression molding materials. It describes: "By rotating a crank rocker arm, a second gear is driven to rotate. The second gear meshes with a first gear. A rotating rod at the center of the first gear drives a turntable to rotate. By placing the material in another fixed mold on top of the turntable for compression molding, the molded product is removed during the compression molding process, which facilitates efficient material discharge and improves processing efficiency." It also describes the technical problem: "However, in the process of molding block compression molding products, existing devices typically use a pressure plate to extrude the block plastic placed in the fixed mold. After the molded part cools, the pressure plate moves upward to remove the product from the fixed mold. The product, subjected to significant extrusion force from the pressure plate, may adhere tightly to the fixed mold and be difficult to remove, delaying secondary material discharge time and resulting in low processing efficiency."

[0004] In summary, existing technologies utilize a turntable to move a fixed mold placed on it, with the fixed mold located below the pressure plate performing compression molding. The molded product is then removed during the compression molding process. However, this method has the following technical problems: the aforementioned device lacks a restraining structure for the fixed mold on the turntable. When the turntable rotates, the fixed mold may move relative to the turntable. When the moved fixed mold performs compression molding, the pressure plate and the fixed mold may become misaligned, requiring readjustment of the fixed mold's position, resulting in relatively low compression molding efficiency. Therefore, this application proposes a high-efficiency block compression molding and unloading device, providing a new technical solution to address the technical problems mentioned in the aforementioned patent. Utility Model Content

[0005] Based on this, it is necessary to provide a high-efficiency block compression molding feeding device to address the aforementioned technical problems. By pulling the U-shaped pull rod, the U-shaped pull rod can be disengaged from the groove on the fixed shell that matches the cross-shaped limiting block, allowing the cross-shaped limiting block on the mold to be inserted into the fixed shell, thus initially restricting the position of the mold. Subsequently, releasing the U-shaped pull rod allows it to be inserted into the cross-shaped limiting block for secondary restriction. This reduces the possibility of displacement of the mold relative to the receiving plate during subsequent rotation of the receiving plate, reduces the possibility of misalignment between the central axis of the mold and the central axis of the pressure plate during subsequent compression molding, and reduces the need for readjustment of the mold position before compression molding, ensuring compression molding efficiency. Furthermore, the guide between the groove inside the fixed shell and the cross-shaped limiting block facilitates the operator in placing the mold in the appropriate position, improving the ease of operation of the device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A high-efficiency device for discharging block compression molding materials, which is applied to block compression molding.

[0008] The high-efficiency block compression molding material discharging device specifically includes:

[0009] The device housing has a support frame fixedly connected to its top, a cylinder body fixedly mounted on the top of the support frame, an installation rod fixedly connected to the output end of the cylinder body, a pressure plate detachably connected to the bottom end of the installation rod via a thread, a receiving mechanism and a limiting mechanism provided on the device housing.

[0010] The receiving mechanism includes a receiving plate, a T-shaped rail, a positioning component, and a plug-in component. The bottom of the receiving plate is fixedly connected to the T-shaped rail, which is rotatably connected to the inner wall of the device housing. The device housing is provided with multiple positioning components, and each of the multiple positioning components is provided with a plug-in component.

[0011] In a preferred embodiment of the block compression molding and feeding high-efficiency device provided by this utility model, the positioning component includes a mold, a connecting block is fixedly connected to the bottom of the mold and located at the center, a cross-shaped limiting block is fixedly connected to the bottom of the connecting block, a fixed shell is fixedly connected to the top of the device housing, and the cross-shaped limiting block is movably inserted into the fixed shell.

[0012] In a preferred embodiment of the block compression molding and feeding high-efficiency device provided by this utility model, the plug-in assembly includes a U-shaped pull rod. The U-shaped pull rod is slidably connected to the inner wall of the fixed shell. Both ends of the U-shaped pull rod are movably inserted into the cross-shaped limiting block. Fixed rings are fixedly connected to the outer wall of the U-shaped pull rod near both ends. Two first springs are sleeved on the outside of the U-shaped pull rod. The two ends of the first springs are fixedly connected to the outer wall of the fixed ring and the inner wall of the fixed shell, respectively.

[0013] As a preferred embodiment of the block compression molding material feeding high-efficiency device provided by this utility model, the limiting mechanism includes a limiting shell, insertion holes, a first pulling component, and a second pulling component. The limiting shell is fixedly connected to the top of the device housing, and multiple insertion holes are provided on the receiving plate.

[0014] In a preferred embodiment of the block compression molding and feeding high-efficiency device provided by this utility model, the first pulling component includes a T-shaped insert. The T-shaped insert is slidably connected to the inner wall of the limiting shell. The T-shaped insert is movably inserted into the insertion hole. A handle is fixedly connected to the outer wall of the T-shaped insert. The handle is slidably connected to the inner wall of the limiting shell. A second spring is fixedly connected to the outer wall of the T-shaped insert. The outer wall of the second spring is fixedly connected to the inner wall of the limiting shell.

[0015] In a preferred embodiment of the block compression molding and feeding high-efficiency device provided by this utility model, the second pulling component includes a pulling block, and a plurality of pulling blocks are fixedly connected to the top of the receiving plate.

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

[0017] The block compression molding high-efficiency feeding device provided by this utility model allows the U-shaped pull rod to be pulled away from the groove on the fixed shell that matches the cross-shaped limiting block, allowing the cross-shaped limiting block on the mold to be inserted into the fixed shell, thus initially restricting the position of the mold. Then, releasing the U-shaped pull rod allows it to be inserted into the cross-shaped limiting block for secondary restriction. This reduces the possibility of mold displacement relative to the receiving plate during subsequent rotation of the receiving plate, reduces the possibility of misalignment between the mold's central axis and the pressure plate's central axis during compression molding, and reduces the need for readjustment of the mold's position before compression molding, ensuring compression molding efficiency. Furthermore, the guide between the groove inside the fixed shell and the cross-shaped limiting block facilitates the operator in placing the mold in the appropriate position, improving the ease of operation of the device.

[0018] The efficient block compression molding feeding device provided by this utility model allows the T-shaped insert to leave the insertion hole by pulling the handle. Then, pulling the pull block will cause the receiving plate to rotate, thereby changing the mold located below the pressure plate. When the next mold is below the pressure plate, there is an insertion hole directly opposite the T-shaped insert. Releasing the handle allows the T-shaped insert to be inserted into the insertion hole. The structure for rotating and restricting the receiving plate and the structure for changing the mold are both set on the outer shell of the device, reducing the frequency of bending over when the operator is working, reducing operator fatigue, and improving the practicality of the device.

[0027] 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.

[0028] As described in the background art, the above-mentioned device lacks a limiting structure for the fixed mold on the turntable. When the turntable rotates, the fixed mold may move relative to the turntable. When the moved fixed mold is used for compression molding, the pressure plate and the fixed mold may become misaligned, and the position of the fixed mold needs to be readjusted, resulting in relatively low compression molding efficiency.

[0029] To solve this technical problem, this utility model provides a high-efficiency device for discharging block compression molding materials, which is applied to block compression molding.

[0030] For details, please refer to Figures 1-2 The high-efficiency device for discharging block compression molding materials specifically includes:

[0031] The device housing 1 has a support frame 2 fixedly connected to its top. A cylinder body 3 is fixedly installed on the top of the support frame 2. An installation rod 4 is fixedly connected to the output end of the cylinder body 3. A pressure plate 5 is detachably connected to the bottom end of the installation rod 4 via a thread. A receiving mechanism 6 and a limiting mechanism 7 are provided on the device housing 1.

[0032] The receiving mechanism 6 includes a receiving plate 8, a T-shaped rail 9, a positioning component, and a plug-in component. The bottom of the receiving plate 8 is fixedly connected to the T-shaped rail 9, which is rotatably connected to the inner wall of the device housing 1. Multiple positioning components are provided on the device housing 1, and each positioning component is equipped with a plug-in component.

[0033] The specific structure and working principle of the cylinder body 3 in this application are the same as those of the cylinders in the prior art mentioned in the background art.

[0034] The efficient block compression molding feeding device provided by this utility model allows the U-shaped pull rod 14 to be pulled away from the groove on the fixed shell 10 that matches the cross-shaped limiting block 13, allowing the cross-shaped limiting block 13 on the mold 11 to be inserted into the fixed shell 10, thus initially restricting the position of the mold 11. Then, releasing the U-shaped pull rod 14 allows it to be inserted into the cross-shaped limiting block 13 for secondary restriction. This reduces the possibility of displacement of the mold 11 relative to the receiving plate 8 during subsequent rotation, reduces the possibility of misalignment between the central axis of the mold 11 and the central axis of the pressure plate 5 during subsequent compression molding, and reduces the need to readjust the position of the mold 11 before compression molding, ensuring compression molding efficiency. Furthermore, the guide between the groove inside the fixed shell 10 and the cross-shaped limiting block 13 facilitates the operator in placing the mold 11 in the appropriate position, improving the ease of operation of the device.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 1-4 A high-efficiency device for discharging block-shaped compression molding materials, comprising:

[0038] The device housing 1 has a support frame 2 fixedly connected to its top. A cylinder body 3 is fixedly installed on the top of the support frame 2. An installation rod 4 is fixedly connected to the output end of the cylinder body 3. A pressure plate 5 is detachably connected to the bottom end of the installation rod 4 via a thread. A receiving mechanism 6 and a limiting mechanism 7 are provided on the device housing 1.

[0039] The receiving mechanism 6 includes a receiving plate 8, a T-shaped rail 9, a positioning component, and a plug-in component. The bottom of the receiving plate 8 is fixedly connected to the T-shaped rail 9, which is rotatably connected to the inner wall of the device housing 1. Multiple positioning components are provided on the device housing 1, and each positioning component is equipped with a plug-in component.

[0040] The positioning component includes a mold 11, a connecting block 12 fixedly connected to the bottom and center of the mold 11, a cross-shaped limiting block 13 fixedly connected to the bottom of the connecting block 12, and a fixed shell 10 fixedly connected to the top of the device housing 1. The cross-shaped limiting block 13 is movably inserted into the fixed shell 10. The positioning component is used to guide the mold 11 to a suitable position within the fixed shell 10. After the cross-shaped limiting block 13 is inserted into the fixed shell 10, the central axis of the mold 11 and the fixed shell 10 are collinear. When producing the mold 11, the connecting block 12, and the cross-shaped limiting block 13, the dimensions of the connecting block 12 and the cross-shaped limiting block 13 can be set to be the same. The mold 11 can be set to different sizes according to the actual compression molding requirements. After welding and assembly, positioning components with different mold 11 sizes but the same dimensions of the connecting block 12 and the cross-shaped limiting block 13 can be obtained to adapt to various compression molding requirements. Correspondingly, various pressure plates 5 with the same size as the mold 11 can be set, all of which are detachably installed on the mounting rod 4 through the same thread.

[0041] The plug-in assembly includes a U-shaped pull rod 14, which is slidably connected to the inner wall of the fixed shell 10. Both ends of the U-shaped pull rod 14 are movably plugged into the cross-shaped limiting block 13. The outer wall of the U-shaped pull rod 14 and near both ends are fixedly connected to fixing rings 15. Two first springs 16 are sleeved on the outside of the U-shaped pull rod 14. The two ends of the first springs 16 are fixedly connected to the outer wall of the fixing rings 15 and the inner wall of the fixed shell 10, respectively. The plug-in assembly can improve the stability of the cross-shaped limiting block 13 installed in the fixed shell 10. Holes that match the U-shaped pull rod 14 are opened in the front, back, left and right sides of the cross-shaped limiting block 13, so that when the cross-shaped limiting block 13 is placed in the groove inside the fixed shell 10, it is only necessary to put the cross-shaped limiting block 13 into the corresponding groove on the fixed shell 10 without considering the specific orientation of the cross-shaped limiting block 13, which improves the convenience of device operation.

[0042] Through the above structural design, when compression molding is required, the mold 11 to be processed is moved directly below the pressure plate 5 with the assistance of the limiting mechanism 7. Then, the cylinder body 3 is controlled to drive the mounting rod 4 and the pressure plate 5 to descend, thereby squeezing the mold 11. During this process, the compressed mold 11 can be disassembled. By pulling the U-shaped pull rod 14, the U-shaped pull rod 14 can be disengaged from the groove on the fixed shell 10 that matches the cross limit block 13, causing the fixing ring 15 to slide relative to the fixed shell 10, so that the corresponding two first The spring 16 deforms accordingly, removing the processed mold 11, its corresponding connecting block 12, and the cross-shaped limiting block 13 from the fixed shell 10. Then, the unprocessed mold 11 with the material is removed, and the cross-shaped limiting block 13 on the unprocessed mold 11 is inserted into the fixed shell 10 to initially restrict the position of the mold 11. Then, the U-shaped pull rod 14 is released, so that the U-shaped pull rod 14 is inserted into the cross-shaped limiting block 13 under the action of the elastic force of the first spring 16, thus providing a secondary restriction on the cross-shaped limiting block 13.

[0043] Example 2:

[0044] The efficient block compression molding discharge device provided in Example 1 is further optimized, specifically, as follows: Figure 2 and Figure 5 As shown, the limiting mechanism 7 includes a limiting shell 17, a socket 20, a first pulling component, and a second pulling component. The limiting shell 17 is fixedly connected to the top of the device housing 1. The receiving plate 8 has multiple sockets 20, and the positions of the sockets 20 correspond to the positions of the fixed shell 10.

[0045] The first pulling assembly includes a T-shaped insert 18. The T-shaped insert 18 is slidably connected to the inner wall of the limiting shell 17. The T-shaped insert 18 is movably inserted into the socket 20. A handle 22 is fixedly connected to the outer wall of the T-shaped insert 18. The handle 22 is slidably connected to the inner wall of the limiting shell 17. A second spring 19 is fixedly connected to the outer wall of the T-shaped insert 18. The outer wall of the second spring 19 is fixedly connected to the inner wall of the limiting shell 17. The first pulling assembly can control the T-shaped insert 18 to be inserted into or removed from the socket 20, that is, to restrict the rotation of the receiving plate 8 and release the rotation restriction of the receiving plate 8. When the T-shaped insert 18 is inserted into the socket 20, there is a central axis of the fixed shell 10 on the receiving plate 8 that is collinear with the central axis of the pressure plate 5.

[0046] The second pulling component includes a pull block 21. Multiple pull blocks 21 are fixedly connected to the top of the receiving plate 8. The second pulling component allows the operator to rotate the receiving plate 8.

[0047] With the above structural design, when it is necessary to rotate the receiving plate 8 to change the mold 11 on the receiving plate 8 corresponding to the pressure plate 5, pulling the handle 22 will cause the T-shaped insert 18 to slide inside the limiting shell 17, causing the second spring 19 to deform. Then, the operator can pull the pull block 21 to make the receiving plate 8 rotate by the T-shaped rail 9, so that the next unprocessed mold 11 is below the pressure plate 5. At this time, there is an insertion hole 20 aligned with the T-shaped insert 18. Then, releasing the handle 22 will allow the T-shaped insert 18 to be inserted into the insertion hole 20 under the elastic force of the second spring 19, thus restricting the rotation of the receiving plate 8. Then, the control cylinder body 3 will drive the mounting rod 4 and the pressure plate 5 to descend for compression molding.
