Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a multi-cavity mold. Background Technology

[0002] Multi-cavity molds are industrial equipment that can simultaneously mold multiple products using a single mold, mainly used to improve production efficiency and reduce unit costs.

[0003] Chinese utility model patent CN222919607U discloses a multi-cavity die-casting mold, including a demolding assembly. The demolding assembly includes an upper mold base, upper mold cavities, a top groove, a top frame, a top rod, a top plate, a gate, a sprue, a sliding hole, an upper shell, and a spring. Multiple upper mold cavities are formed on the lower surface of the upper mold base. This utility model, by having multiple upper and lower mold cavities corresponding to both the upper and lower mold bases, allows for the simultaneous production of multiple die-casting parts in a single die-casting process. During the upward movement of the upper mold base, the spring force automatically pushes the top plate downward, causing the top frame to eject the die-casting part from the upper mold cavity. Furthermore, an electric cylinder drives the push rod and the push plate, enabling rapid ejection of the die-casting part from the lower mold cavity. This reduces manual operation and improves the degree of automation and production efficiency. Simultaneously, the top frame and push plate clean the inner walls of the upper and lower mold cavities, increasing the cleaning speed and further improving production efficiency.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1 Please see Figure 1 - Figure 8 A multi-cavity mold, comprising: Base 1; The lower mold base 2 is fixedly installed on the top of the base 1; Lifting component 3 is mounted on base 1; The upper mold base 4 is fixedly installed on the inner top wall of the lifting assembly 3; Multiple rows of mounting cavities 5 are respectively opened on the lower mold base 2 and the upper mold base 4; Mold cores 6 are respectively set in multiple rows of mounting cavities 5; Two square holes 7 are symmetrically opened on both sides of the mold core 6; Multiple T-slots are respectively opened on the lower mold base 2 and the upper mold base 4; And multiple fixing components 8 are provided in the T-shaped groove, and one end of the fixing component 8 is inserted into the square hole 7.

[0023] This utility model provides a multi-cavity mold. In use, by manually moving the fixing component 8 at the corresponding position and removing one end of it from the square hole 7, a single damaged mold core 6 can be removed from the mounting cavity 5 on the lower mold base 2 or the upper mold base 4. Then, a new mold core 6 is inserted into the mounting cavity 5, and the corresponding fixing component 8 is moved so that one end of it is reinserted into the square hole 7 for fixation. Thus, if a single cavity is damaged due to wear, impact, corrosion, or accidental molding, it is not necessary to replace or disassemble the entire mold plate. Only the damaged single insert needs to be removed for repair or replacement.

[0024] Furthermore, the fixing component 8 includes multiple pairs of connecting rods 81 disposed in the T-shaped groove. Each pair of connecting rods 81 has a pair of T-shaped rods 82 disposed on its outer side wall. One end of the T-shaped rod 82 is inserted into the square hole 7. One end of the T-shaped rod 82 is provided with a magnetic attraction mechanism 83. The T-shaped rod 82 is attracted and fixed to the mold core 6 through the magnetic attraction mechanism 83.

[0025] Specifically, by manually moving the T-shaped rod 82 on the connecting rod 81 and removing one end of it from the square hole 7, the corresponding mold core 6 can be removed. Then, the new mold core 6 is inserted into the mounting cavity 5. Then, the T-shaped rod 82 on the connecting rod 81 is moved so that one end is reinserted into the square hole 7. With the cooperation of the magnetic attraction mechanism 83, the new mold core 6 can be stably fixed in the mounting cavity 5.

[0026] Furthermore, the magnetic attraction mechanism 83 includes a magnet one fixedly installed at one end of the T-shaped rod 82, a magnet two provided inside the square hole 7, and the magnet two fixedly installed on the mold core 6, with the magnet one and the magnet two adsorbing each other.

[0027] Specifically, when the T-shaped rod 82 is inserted into the square hole 7, magnet one and magnet two attract each other, so that the T-shaped rod 82 can be stably inserted and fixed in the square hole 7, thereby ensuring the stability of the mold core 6.

[0028] Furthermore, a plurality of cross posts 9 are provided between the lower mold base 2 and the upper mold base 4, and the upper and lower ends of the cross posts 9 are respectively inserted into the T-shaped grooves on the lower mold base 2 and the upper mold base 4.

[0029] Specifically, the cross post 9 can both protect the fixing component 8 and ensure the alignment accuracy of the upper mold base 4 and the lower mold base 2.

[0030] Furthermore, the lifting assembly 3 includes two cylinders 31 symmetrically fixedly installed on the base 1, and a connecting plate 32 is fixedly installed on the top of the two cylinders 31, and the upper mold base 4 is fixedly installed on the bottom of the connecting plate 32.

[0031] Specifically, the retracting cylinder 31 drives the connecting plate 32 to descend, thereby enabling the upper mold base 4 to fit against the lower mold base 2.

[0032] Furthermore, through holes are provided on the connecting plate 32, the upper mold base 4, and the mold core 6 located in the upper mold base 4. An injection pipe 13 is provided in the through hole connecting the connecting plate 32, the upper mold base 4, and the mold core 6, and the injection pipe 13 is fixedly installed on the upper mold base 4.

[0033] Specifically, liquid can be injected into the mold core 6 for molding through the injection tube 13 in the connecting hole.

[0034] Furthermore, four limiting rods 14 are fixedly installed on the top of the base 1 in a rectangular arrangement, and the connecting plate 32 is located on the limiting rods 14.

[0035] Specifically, the limiting rod 14 ensures the stability of the cylinder 31 in raising and lowering the connecting plate 32.

[0036] Example 2 Based on Embodiment 1, in this embodiment: grooves are provided on both sides of the lower mold base 2 and the upper mold base 4, and a buffer shell 10 is provided on the inner side of the groove. Two elastic components 11 are symmetrically arranged on the inner top wall of the buffer shell 10, and the bottom of the elastic component 11 is fixedly connected to the lower mold base 2.

[0037] The technical solution provided in this embodiment is as follows: when the upper mold base 4 descends and fits with the lower mold base 2, the upper mold base 4 will first press the buffer shell 10 on the elastic component 11, and then the impact energy of the upper mold base 4 can be absorbed through the elastic component 11, thereby effectively reducing the collision and wear between the lower mold base 2 and the upper mold base 4.

[0038] Furthermore, the elastic component 11 includes an inverted T-shaped cylinder 1101 fixedly installed on the lower mold base 2, an inverted T-shaped rod 1102 is provided on the inner side of the inverted T-shaped cylinder 1101, and the top of the inverted T-shaped rod 1102 is fixedly connected to the inner top wall of the buffer shell 10. A spring is provided on the outer side of the inverted T-shaped cylinder 1101, and the spring is located between the lower mold base 2 and the buffer shell 10.

[0039] Specifically, the inverted T-tube 1101 and inverted T-rod 1102 ensure the stability of the buffer shell 10 during descent. Then, with the help of the spring, the impact energy of the upper mold base 4 can be absorbed, thereby effectively reducing the collision and wear between the lower mold base 2 and the upper mold base 4.

[0040] Furthermore, a rubber pad 12 is fixedly installed on the top of the buffer shell 10.

[0041] Specifically, the rubber pad 12 can not only prevent hard contact between the buffer shell 10 and the upper mold base 4, which would cause significant wear, but also further improve the impact energy absorption effect.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
