Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to an opening and closing mechanism and a molding device. Background Art

[0002] In mold manufacturing and injection molding processes, precise control of the mold opening and closing sequence is crucial. The correct opening and closing sequence helps prevent mold damage, ensure product quality, and improve production efficiency. Traditional mold openers and closers are often limited to a single opening and closing function and cannot flexibly control the specific order of mold opening and closing. In order to achieve specific opening and closing sequence requirements, such as first opening the male mold and the springboard located on the side of the male mold facing away from the female mold during the mold opening process, and then opening the male mold and female mold, and first closing the male mold and female mold before closing the springboard and male mold during the mold closing process, additional mechanical control devices or complex electronic control systems are usually required to control the mold opening and closing sequence, which not only increases manufacturing costs, but may also affect the operating efficiency and reliability of the mold. Utility Model Content

[0003] In view of the above situation, it is necessary to provide an opening and closing mechanism and a molding device to control the opening and closing sequence of the female mold, the male mold and the springboard and reduce the equipment cost.

[0004] The present application provides an opening and closing mechanism for use in a molding die having a female mold, a male mold, and a springboard stacked therein. The opening and closing mechanism includes:

[0005] A limiting assembly, wherein the front end of the limiting assembly is fixed to a side surface of the female mold, the rear end of the limiting assembly is movably extended toward a side surface of the male mold, and the limiting assembly is provided with a receiving groove;

[0006] A locking assembly, wherein the front end of the locking assembly is fixed to a side surface of the springboard, the rear end of the locking assembly is slidably connected to the limiting assembly, and a supporting groove is formed between the two ends of the locking assembly;

[0007] a first elastic component, one end of which is movably inserted into the male mold, and the other end of which extends out of the male mold and is inserted into the receiving groove and the supporting groove when the mold is closed;

[0008] a second elastic component, one end of the second elastic component being movably inserted into the male mold at a distance from the first elastic component, and the other end surface of the second elastic component movably abutting against the front end of the locking component when the mold is closed;

[0009] During mold opening, the locking assembly moves along the mold opening direction driven by the springboard to push the first elastic component to retract from the receiving groove and the abutting groove into the male mold to release the limiting component and the female mold, and the end face of one end of the second elastic component slides into the abutting groove from the front end of the locking assembly to lock the locking assembly and the springboard;

[0010] During mold closing, the limiting component moves along the mold closing direction driven by the female mold, and pushes the second elastic component to retract from the abutting groove into the male mold to release the locking assembly and the springboard.

[0078] The following will detail some embodiments of the present application with reference to the drawings.

[0079] Please refer to Figure 1 and Figure 2, an embodiment of the present application provides a molding device 300, which includes a mold opening and closing mechanism 100 and a molding die 200. The mold opening and closing mechanism 100 is applied to the molding die 200 and includes a limiting component 10, a locking component 20, a first elastic component 30, and a second elastic component 40. The molding die 200 includes a female mold 201, a male mold 202, and a springboard 203 that are sequentially stacked and opened and matched. The mold opening and closing mechanism 100 can cooperate with a power source to control the opening and closing sequence of the female mold 201, the male mold 202, and the springboard 203, so as to realize opening the male mold 202 and the springboard 203 first during the mold opening process, and then opening the male mold 202 and the female mold 201. During the mold closing process, the male mold 202 and the female mold 201 are closed first, and then the male mold 202 and the springboard 203 are closed.

[0080] Please refer to Figure 2 and Figure 3 , the front end of the limiting component 10 is fixed to one side of the female mold 201, the end of the limiting component 10 extends movably toward one side of the male mold 202, and a receiving groove 11 is formed on the side of the limiting component 10 facing the male mold 202. The front end of the locking component 20 is fixed to one side of the springboard 203, the end of the locking component 20 is slidably connected to the limiting component 10, and a resisting groove 21 is formed between the two ends of the locking component 20.

[0081] Please refer to Figure 2 , Figure 4 and Figure 5 , one end of the first elastic component 30 is movably inserted into the male mold 202, and the other end of the first elastic component 30 extends out of the male mold 202 and is inserted into the receiving groove 11 and the resisting groove 21 during mold closing. One end of the second elastic component 40 and the first elastic component 30 are spaced apart and movably inserted into the male mold 202, and the end face of the other end of the second elastic component 40 movably abuts against the front end of the locking component 20 during mold closing.

[0082] During mold opening, the locking component 20 moves along the mold opening direction driven by the springboard 203, pushing the first elastic component 30 to retract from the receiving groove 11 and the resisting groove 21 into the male mold 202 to release the limiting component 10 and the female mold 201. At this time, the female mold 201 is not locked by the interaction of the first elastic component 30, the locking component 20, and the limiting component 10, and it can be opened in the mold opening direction to take out the workpiece formed in the molding die 200. The locking component 20 moves along the mold opening direction driven by the springboard 203, and one end face of the second elastic component 40 slides from the side of the front end of the locking component 20 and is inserted into the resisting groove 21 to lock the locking component 20 and the springboard 203, preventing a large distance from being opened between the springboard 203 and the male mold 202.

[0083] During mold clamping, the limiting component 10 moves along the mold clamping direction driven by the female mold 201. The end of the limiting component 10 abuts against and pushes the second elastic component 40 to retract from the abutting groove 21 into the male mold 202 to release the locking component 20 and the springboard 203. The released locking component 20 moves along the mold clamping direction driven by the springboard 203, so that the first elastic component 30 retracted into the male mold 202 extends into the receiving groove 11 and the abutting groove 21 to lock the limiting component 10 and the female mold 201.

[0084] After the molding die 200 is clamped, the first elastic component 30 is inserted into the receiving groove 11 and the abutting groove 21 and locks the limiting component 10 and the female mold 201, thereby limiting the male mold 202 and the female mold 201 to prevent the male mold 202 and the female mold 201 from opening prior to the male mold 202 and the springboard 203 during the mold opening process; during the mold opening process, the springboard 203 drives the locking component 20 to move synchronously in the direction away from the male mold 202 to first open the male mold 202 and the springboard 203, and the side surface of the end of the locking component 20 abuts and pushes the first elastic component 30 to retract into the male mold 202, so that the first elastic component 30 releases the limiting component 10 and the female mold 201. Then the springboard 203 continues to drive the locking component 20 to slide away from the front side surface 232 of the outer end surface of the second elastic component 40. As the springboard 203 drives the locking component 20 to continue to move in the direction away from the male mold 202, the released second elastic component 40 slides into the abutting groove 21 from the front side surface 232 of the locking component 20 and locks the locking component 20 and the springboard 203, thereby limiting the springboard 203 and the male mold 202 to prevent the springboard 203 and the male mold 202 from closing prior to the male mold 202 and the female mold 201 during the mold clamping process. Finally, the female mold 201 drives the limiting component 10 to move in the direction away from the male mold 202 to open the male mold 202 and the female mold 201 later, so as to take out the workpiece formed in the molding die 200.

[0085] During the mold clamping process, the female mold 201 drives the limit component 10 to move in the direction close to the male mold 202 to first close the male mold 202 and the female mold 201. At the same time, the end side of the limit component 10 is driven by the female mold 201 to push the second elastic component 40 to retract into the male mold 202, so that the second elastic component 40 releases the locking component 20 and the springboard 203. Then, the springboard 203 drives the locking component 20 to move in the direction close to the male mold 202 to close the male mold 202 and the springboard 203. At the same time, the front side 232 of the locking component 20 abuts against the second elastic component 40 retracted into the male mold 202, and the end side of the locking component 20 is separated from the first elastic component 30, so that the separated first elastic component 30 slides into the receiving groove 11 and the abutting groove 21 from the end side of the locking component 20 and locks the limit component 10 and the female mold 201. In this way, the mold opening and closing mechanism 100 and the molding device 300 cooperate with each other through the locking component 20, the limit component 10, the first elastic component 30, and the second elastic component 40, and can control the opening and closing sequence of the female mold 201, the male mold 202, and the springboard 203, realizing that the male mold 202 and the springboard 203 are first opened during the mold opening process, then the male mold 202 and the female mold 201 are opened, and during the mold clamping process, the male mold 202 and the female mold 201 are first closed, and then the male mold 202 and the springboard 203 are closed. Moreover, the mechanical structure of the mold opening and closing mechanism 100 is simple, without the need to use complex mechanical control devices or electronic control systems, reducing the equipment cost.

[0086] Please refer to Figure 2 and Figure 3 In some embodiments, two mounting holes 2021 are provided in the male mold 202 to respectively mount the first elastic component 30 and the second elastic component 40. Both the first elastic component 30 and the second elastic component 40 include an elastic member 31 and a sliding member 32. The elastic member 31 is disposed in the mounting hole 2021, and the sliding member 32 is disposed in the mounting hole 2021. One end of the sliding member 32 of the first elastic component 30 presses the elastic member 31 in the mounting hole 2021. The other end face of the sliding member 32 of the first elastic component 30 abuts against the end side of the locking component 20 during mold opening and inserts into the receiving groove 11 during mold clamping. One end of the sliding member 32 of the second elastic component 40 presses the elastic member 31 in the mounting hole 2021. The end face of the other end of the sliding member 32 of the second elastic component 40 inserts into the abutting groove 21 during mold opening and abuts against the front side 232 of the locking component 20 during mold clamping. Exemplarily, the elastic member 31 can be a spring.

[0087] Thus, when the slider 32 is subjected to the driving force applied by the corresponding limiting component 10 or locking component 20, the elastic member 31 is compressed into the male mold 202 under the pushing of the slider 32. During mold closing, the elastic member 31 of the first elastic component 30 provides elastic force and drives the corresponding slider 32 to move and insert into the receiving groove 11 to lock the limiting component 10 and the female mold 201. During mold opening, the elastic member 31 of the second elastic component 40 provides elastic force to drive the corresponding slider 32 to move and insert into the abutting groove 21 to lock the locking component 20 and the springboard 203, thereby realizing locking of different components during mold opening and mold closing respectively, and controlling the sequence of mold opening and closing in this way.

[0088] Please refer to Figure 3 , in some embodiments, the slider 32 includes a sliding boss 321 and a sliding abutting plate 322. The sliding boss 321 movably presses the elastic member 31 against the bottom wall of the mounting hole 2021. The sliding boss 321 protrudes from the sliding abutting plate 322. The sliding abutting plate 322 of the first elastic component 30 movably abuts against the end of the locking component 20 during mold opening and movably inserts into the receiving groove 11 and the abutting groove 21 during mold closing; the sliding abutting plate 322 of the second elastic component 40 movably inserts into the abutting groove 21 during mold opening and movably abuts against the front end of the locking component 20 during mold closing.

[0089] In some embodiments, the sliding abutting plate 322 has a sliding surface 3221 and an abutting inclined surface 3222 that is inclinedly connected to the sliding surface 3221. The abutting groove 21 has a pushing inclined surface 211, and the pushing inclined surface 211 slidably abuts against the abutting inclined surface 3222 of the first elastic component 30 to push the first elastic component 30 to retract from the receiving groove 11 into the male mold 202. The end of the limiting component 10 has a pressing inclined surface 12, and the pressing inclined surface 12 slidably abuts against the abutting inclined surface 3222 of the second elastic component 40 to push the second elastic component 40 to retract from the abutting groove 21 into the male mold 202.

[0090] Thus, when the mold is opened, the pushing inclined surface 211 slides and abuts against the abutting inclined surface 3222 of the first elastic component 30 to push the first elastic component 30 to retract from the receiving groove 11 and the abutting groove 21 into the male mold 202, so that the first elastic component 30 releases the limiting component 10 and the female mold 201. When the mold is closed, the pressing inclined surface 12 slides and abuts against the abutting inclined surface 3222 of the second elastic component 40 to push the second elastic component 40 to retract from the abutting groove 21 into the male mold 202, so that the second elastic component 40 releases the locking component 20 and the springboard 203, thereby controlling the opening and closing sequence of the molding die 200. In addition, by providing the above-mentioned sliding surface 3221, the locking component 20 can form a planar contact with the second elastic component 40 through the sliding surface 3221 during mold closing and stably compress the second elastic component 40 to retract into the male mold 202, and the locking component 20 can also form a planar contact with the second elastic component 40 through the sliding surface 3221 during mold opening and stably compress the first elastic component 30 to retract into the male mold 202.

[0091] Please refer to Figure 3 , Figure 4 and Figure 5 , in some embodiments, the closer mechanism 100 further includes a stop component 50, the stop component 50 includes two stop members 51, the two stop members 51 are spaced apart on one side surface of the male mold 202 and form a sliding space 511, and the limiting component 10 slides in the sliding space 511.

[0092] Thus, the limiting component 10 is received through the sliding space 511 formed by the two stop members 51, and the sliding space 511 can limit the movement direction of the limiting component 10 to prevent the direction of the limiting component 10 from shifting, thereby improving the mold opening and closing accuracy.

[0093] In some embodiments, a receiving groove 512 is provided on one side of each stop member 51 facing the male mold 202, the receiving groove 512 is respectively communicated with the receiving groove 11 and the abutting groove 21, and when the sliding abutting plate 322 is inserted into the receiving groove 11 and / or the abutting groove 21 during mold opening or closing, both ends of the sliding abutting plate 322 slide in the receiving grooves 512 of the two stop members 51.

[0094] Thus, by the bottom of the receiving groove 512 abutting against the sliding abutting plate 322 of the first elastic component 30 inserted into the receiving groove 11 and the abutting groove 21 during mold closing and abutting against the sliding abutting plate 322 of the second elastic component 40 inserted into the abutting groove 21 during mold opening, the stop member 51 can limit the distance of the sliding member 32 protruding from the male mold 202, preventing the sliding member 32 from moving too far in the direction away from the elastic member 31 under the drive of the elastic member 31 and disengaging from the male mold 202, so that one end of the sliding member 32 adjacent to the elastic member 31 always penetrates into the male mold 202, facilitating the sliding member 32 to repeatedly perform locking operations and release operations.

[0095] Please refer to Figure 3 Figure 3 , in some embodiments, the locking assembly 20 includes a connecting block 22 and a locking rod 23. The connecting block 22 is fixed to one side of the springboard 203. The locking rod 23 protrudes from the connecting block 22 and is slidably connected to the limiting assembly 10, and an abutting groove 21 is formed on one side of the locking rod 23 facing the first elastic assembly 30.

[0096]

[0096] In this way, by setting the specific structure of the above-mentioned locking assembly 20, the locking rod 23 can correspond to the first elastic assembly 30 and the second elastic assembly 40. When the springboard 203 drives the locking rod 23 to move synchronously through the connecting block 22, the locking rod 23 stably acts on the corresponding first elastic assembly 30 and second elastic assembly 40, so that the first elastic assembly 30 and the second elastic assembly 40 can stably perform locking operations or unlocking operations, improving the stability of mold opening and closing.

[0097] In some embodiments, both ends of the locking rod 23 have a rear end side surface 231 and a front end side surface 232. Both sides of the abutting groove 21 are respectively connected to the rear end side surface 231 and the front end side surface 232. Further, the pushing inclined surface 211 of the abutting groove 21 is connected to the rear end side surface 231, and the rear end side surface 231 abuts against the sliding abutting plate 322 of the first elastic assembly 30 during mold opening, and the front end side surface 232 abuts against the sliding abutting plate 322 of the second elastic assembly 40 during mold closing. Among them, the rear end side surface 231, the abutting groove 21 and the front end side surface 232 are located on the same side of the locking rod 23 and are arranged in sequence along the direction from the female mold 201 to the male mold 202.

[0098] In this way, by setting the above-mentioned rear end side surface 231 and front end side surface 232, the locking rod 23 can abut against the sliding abutting plate 322 of the first elastic assembly 30 through the rear end side surface 231 during mold opening, and abut against the second elastic assembly 40 through the front end side surface 232 during mold closing, so that the locking assembly 20 forms a planar contact with the sliding abutting plate 322 of the first elastic assembly 30 or the sliding abutting plate 322 of the second elastic assembly 40. Furthermore, the locking rod 23 stably abuts against the sliding abutting plate 322 of the first elastic assembly 30 or the sliding abutting plate 322 of the second elastic assembly 40, so that the locking rod 23 stably applies a driving force to the sliding abutting plate 322 of the first elastic assembly 30 or the sliding abutting plate 322 of the second elastic assembly 40 along the direction from the sliding member 32 to the elastic member 31, so that the first elastic assembly 30 or the second elastic assembly 40 stably maintains the state of being retracted into the male mold 202.

[0099] Please refer to Figure 3, in some embodiments, the limiting component 10 includes a limiting bottom plate 13, two limiting protrusions 14 and two fixing protrusions 15. The two limiting protrusions 14 are spaced apart on the limiting bottom plate 13 to form a limiting groove 141. The locking component 20 slides in the limiting groove 141 during mold opening and closing. A pressing inclined surface 12 is formed at the end of the limiting protrusion 14. A receiving groove 11 is opened in the limiting protrusion 14 and communicated with the limiting groove 141. The two fixing protrusions 15 are respectively arranged at one end of the two limiting protrusions 14 to be fixedly connected to one side of the female mold 201.

[0100] In this way, by connecting the limiting bottom plate 13 with the two limiting protrusions 14, the limiting bottom plate 13 and the two limiting protrusions 14 can cooperate with each other to enclose and form the limiting groove 141. Thereby, the locking component 20 is received and limited through the limiting groove 141 after mold closing, and further, the locking component 20 moves along the extending direction of the limiting groove 141 during mold opening and closing, improving the stability of mold opening and closing.
