Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to mold bonding structures and molds thereof. Background Technology

[0002] Mold fitting structure refers to the structure in a mold used to tightly connect and fit two or more components to achieve a specific molding function. Positioning pins and positioning holes are common mold fitting structures, consisting of positioning pins and positioning holes. Positioning pins are typically installed on one component of the mold, while positioning holes are located on the other component that it mates with. During mold closing, the positioning pins are inserted into the positioning holes, playing a role in precise alignment and positioning. This ensures that the upper and lower molds or other related components of the mold can accurately fit together during the mold closing process, preventing misalignment and thus ensuring the dimensional accuracy and quality of the molded product. This structure has high positioning accuracy, effectively improving the service life and production efficiency of the mold, and is widely used in various injection molds, die-casting molds, etc.

[0003] In the actual process of assisting mold fitting through the cooperation of positioning pins and positioning holes, if residual molten metal, molding sand and other debris on the mold surface are not cleaned in time after molding, these debris will be stuck between the upper and lower molds during the next mold closing, causing gap differences in the mold after fitting and affecting the mold's processing quality of the product. Therefore, we propose a mold fitting structure and its mold. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention. Example

[0018] Please see Figures 1-8 The mold shown in the figure includes a lower mold 101 and an upper mold 102. Guide posts 103 for assisting the lifting and lowering of the upper mold 102 are provided between the four corners of the upper mold 102 and the lower mold 101. Lifting components for assisting the lifting and lowering of the upper mold 102 are provided on the upper mold 102.

[0019] The mold bonding structure includes mounting plates 201 fixed to the four sides of the upper mold 102, and the mounting plates 201 are evenly distributed on the upper mold 102. The lower end of the mounting plate 201 is fixed with a positioning pin 202. Multiple sets of mounting boxes 203 are evenly distributed around the outer perimeter of the lower mold 101. Each set of mounting boxes 203 is matched with each set of mounting plates 201. The upper end of the mounting box 203 is provided with a positioning hole 204 for positioning with the positioning pin 202. The positioning hole 204 communicates with the inner side of the mounting box 203. Identification components for status recognition during the positioning bonding process are provided at the corners of the lower mold 101. The identification components are centrally located between two adjacent sets of mounting boxes 203. It should be noted that during the process of driving the upper mold 102 to move towards the lower mold 101 under force, the movement of the upper mold 102 drives the synchronous movement of each set of mounting plates 201 and positioning pins 202. During the movement of the mounting plates 201 and positioning pins 202, the front ends of each set of positioning pins 202 are inserted into the positioning holes 204 of each set of mounting boxes 203. Through the insertion of the positioning pins 202 and the positioning holes 204, the positioning pins 202 play a role in precise alignment and positioning during the mold closing process, ensuring that the upper and lower molds or other related components of the mold can accurately fit together during the mold closing process, preventing misalignment, and thus ensuring the dimensional accuracy and quality of the molded product.

[0020] Preferably, the identification component includes a mounting bracket 301 fixed at the corner of the lower mold 101, a rotating shaft 302 rotatably connected to the mounting bracket 301, a pointer 303 fixed on the rotating shaft 302, a scale 304 for identifying the rotation amplitude of the pointer 303 on the mounting bracket 301, a rotating component for rotating the rotating shaft 302 on the lower mold 101, elastic components for assisting in the elastic pushing of the rotating shaft 302 symmetrically arranged on both sides of the rotating component, and a transmission component for transmitting the elastic components on the mounting box 203; It should be noted that during the actual process of driving the upper mold 102 to move towards the lower mold 101 under force, due to the presence of sand and debris on the mold, gap differences will occur at the four corners of the upper mold 102 and lower mold 101 after they are joined. This gap difference will cause the push plates 701 at different positions to be pushed down to different degrees. Because of the different descent distances of the push plates 701, during the transmission process between the pushing and transmission components, the distances that the transmission rods 602 are pushed outward will differ, further causing different elastic components to exert different forces on the connecting plate 402. The elastic force of the connecting plate 402 is such that the elastic force pushing force of the connecting plate 402 on both sides of the connecting plate 402 is deviated, causing the connecting plate 402 and the rotating shaft 302 to rotate under force. The rotation of the rotating shaft 302 drives the pointer 303 to rotate. Therefore, in the process of driving the upper mold 102 to move towards the lower mold 101 under force, by identifying whether each group of pointers 303 deflects and the magnitude of the deflection, it is possible to determine whether there is a gap difference and the size of the gap difference at the four corners of the upper mold 102 and the lower mold 101 after bonding, which further facilitates high-quality processing operations after mold bonding.

[0021] Preferably, the rotating assembly includes a support frame 401 fixed at the corner of the lower mold 101, the support frame 401 is located below the mounting frame 301, the rotating shaft 302 is rotatably connected to the support frame 401, and a connecting plate 402 for auxiliary transmission is fixed on the rotating shaft 302. It should be noted that the support frame 401 and the connecting plate 402 facilitate the rotation of the rotating shaft 302.

[0022] Preferably, the elastic component includes a first sleeve 501, a first slide rod 502 slidably connected to the first sleeve 501, a rectangular plate 503 fixed to one end of the first slide rod 502, a connecting block 504 rotatably connected to one side of the rectangular plate 503 via a pin, the connecting block 504 slidably connected to one side of the connecting plate 402, a baffle 505 fixed to the end of the first sleeve 501 away from the first slide rod 502, and a first spring 506 sleeved on the outside of the first sleeve 501, with the two ends of the first spring 506 respectively abutting against the rectangular plate 503 and the baffle 505; It should be noted here that: the connecting plate 402 is elastically compressed by the elastic force of the first spring 506 and the connecting action of the rectangular plate 503 and the connecting block 504. During the normal compression process, since the elastic force of the elastic components on both sides of the connecting plate 402 is the same, the connecting plate 402 and the rotating shaft 302 do not rotate. During the compression process, through transmission, the first slide rod 502 is forced to slide on the first sleeve 501 and the first spring 506 is deformed to generate a greater elastic force, thereby realizing the adjustment of the elastic force.

[0023] Preferably, the transmission assembly includes a transmission plate 601 disposed inside the mounting box 203, a transmission rod 602 slidably connected to the mounting box 203, the two ends of the transmission rod 602 being fixed to the transmission plate 601 and the baffle 505 respectively, a pushing assembly for pushing the transmission plate 601 is disposed inside the mounting box 203, and a guiding assembly for guiding the transmission plate 601 during the transmission process is disposed inside the mounting box 203; It should be noted here that: through transmission, the transmission plate 601, after being subjected to force, moves towards the outside of the mounting box 203. During the movement of the transmission plate 601, the first sleeve 501 is pushed by the connecting transmission action of the transmission rod 602. During the pushing process, the first slide rod 502 is subjected to force and slides on the first sleeve 501, and the first spring 506 is deformed by force to generate greater elastic force. Through the elastic force of the first spring 506 and the connecting action of the rectangular plate 503 and the connecting block 504, the connecting plate 402 is elastically squeezed.

[0024] Preferably, the pushing component includes a push plate 701 disposed inside the mounting box 203 for abutting and driving against the positioning pin 202. The mounting box 203 is provided with a pressing component for elastically pressing the push plate 701. Under the pressing and pushing of the pressing component, the push plate 701 abuts against the inner side of the mounting box 203. A connecting plate 702 for transmission is provided between the push plate 701 and the transmission plate 601. The two ends of the connecting plate 702 are rotatably connected to the transmission plate 601 and the push plate 701 respectively by a pin. It should be noted that when the front end of the positioning pin 202 is inserted into the positioning hole 204 of the mounting box 203, the front end of the positioning pin 202 abuts against the push plate 701 inside the mounting box 203. During the abutment process, the push plate 701 is pushed to move under force. During the movement of the push plate 701, the sliding guide action of the two sets of third sleeves 901 and the two sets of third slide rods 902 causes the pushed plate 701 to move downward inside the mounting box 203. During the movement of the push plate 701, the connecting transmission action of the connecting plate 702 pushes the transmission plate 601 to move under force. During the movement of the transmission plate 601, the guiding action of the guiding component causes the transmission plate 601 to move towards the outside of the mounting box 203.

[0025] Preferably, the guide assembly includes multiple sets of second sleeves 801 fixed inside the mounting box 203, and a second slide rod 802 is slidably connected to each set of second sleeves 801. One end of the second slide rod 802 is fixed to one side of the transmission plate 601. It should be noted here that the multiple sets of second sleeves 801 and second slide rods 802 facilitate the guidance of the transmission plate 601 after it is subjected to force.

[0026] Preferably, the extrusion assembly includes two sets of third sleeves 901 fixed inside the mounting box 203, and the two sets of third sleeves 901 are arranged symmetrically. A third slide rod 902 is slidably connected to the third sleeve 901. One end of the third slide rod 902 is fixed to the push plate 701. A second spring 903 is sleeved on the outside of the third sleeve 901. The two ends of the second spring 903 are respectively abutted against the inner wall of the mounting box 203 and the push plate 701. It should be noted here that the extension and retraction of the push plate 701 after being subjected to force is guided by two sets of third sleeves 901 and third slide rods 902. The elastic force of the second spring 903 facilitates the push plate 701 to be pushed and kept against the inner wall of the mounting box 203.

[0027] In this solution, the mold bonding structure includes the following steps: During the mold processing, the upper mold 102 moves toward or away from the lower mold 101 through the telescopic guidance of the lifting component and multiple sets of guide pillars 103. The opening and closing operations of the mold are realized through the movement of the upper mold 102. During the process of driving the upper mold 102 to move towards the lower mold 101 under force, the movement of the upper mold 102 drives the synchronous movement of each set of mounting plates 201 and positioning pins 202. During the movement of the mounting plates 201 and positioning pins 202, the front ends of each set of positioning pins 202 are inserted into the positioning holes 204 of each set of mounting boxes 203. Through the insertion of the positioning pins 202 into the positioning holes 204, precise alignment and positioning are achieved during mold closing, ensuring accurate fitting of the upper and lower molds or other related components during mold closing, preventing misalignment, and thus ensuring the dimensional accuracy and quality of the molded product. When the front end of the positioning pin 202 is inserted into the positioning hole 204 of the mounting box 203, it abuts against the push plate 701 inside the mounting box 203. During this abutment, the push plate 701 is pushed and moved under force. During the process, the sliding guide action of the two sets of third sleeves 901 and the two sets of third slide rods 902 causes the force-bearing push plate 701 to move downward inside the mounting box 203. During the movement of the push plate 701, the connecting plate 702 drives the transmission plate 601 to move under force. During the movement of the transmission plate 601, the guiding component guides the force-bearing transmission plate 601 towards the outside of the mounting box 203. During the movement of the transmission plate 601, the connecting rod 602 pushes the first sleeve 501. During this pushing process, the first slide rod 502 slides on the first sleeve 501 under force, causing the first spring 506 to deform and generate greater elastic force. Through the elastic force of the first spring 506 and the connecting action of the rectangular plate 503 and the connecting block 504, the connecting plate 402 is elastically compressed (see...). Figure 5Since the elastic components on both sides of the connecting plate 402 exert the same force on it, the connecting plate 402 and the rotating shaft 302 do not rotate at this time. In the actual process of driving the upper mold 102 to move towards the lower mold 101 under force, due to the presence of sand and debris on the mold, gap differences will occur at the four corners of the upper mold 102 and lower mold 101 after they are joined. Because of these gap differences, the push plates 701 at different positions will be pushed down to different degrees. Furthermore, due to the different descent distances of the push plates 701, during the transmission process between the pushing and transmission components, the outward pushing distances of each set of transmission rods 602 will differ, further causing each set of elastic components to generate different elastic forces on the connecting plate 402. Because of the deviation in the elastic pushing force of the elastic components on both sides of the connecting plate 402, the connecting plate 402 and the rotating shaft 302 are rotated due to the force. The rotation of the rotating shaft 302 drives the pointer 303 to rotate. Therefore, during the process of driving the upper mold 102 to move towards the lower mold 101 under force, by identifying whether each set of pointers 303 deflects and the magnitude of the deflection, it is possible to determine whether there is a gap difference at the four corners of the upper mold 102 and the lower mold 101 after bonding and the size of the gap difference. This further facilitates high-quality processing operations after the mold is bonded.
