Description

A space-saving row structure Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a sliding structure that saves a lot of space. Background Technology

[0002] In daily life, there are many times when the product structure is quite complex, and it is generally impossible to produce with a mold. In most cases, it is produced by breaking it down into multiple small parts and then assembling them. As shown in Figure 1, this part consists of an upper arc surface a, a bottom support column b, and a hemispherical pressure head c. The diameter of the pressure head c is smaller than the diameter of the support column b. The pressure head c can be used to assemble this part with another part. However, when producing this part with a mold, the pressure head c requires a sliding mechanism for demolding, and it is not suitable for demolding with a slanted ejector. Although it is possible to produce this part with a traditional mold structure, when producing multiple parts in one mold, the mold size becomes larger and the machine weight increases accordingly, thus greatly increasing the cost and the machine footprint. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a space-saving sliding structure to solve the technical problem that when producing this part with existing molds, the mold size is large, the machine weight is also heavy, the production cost will be greatly increased, and the machine footprint will be large.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A space-saving sliding structure includes a mold body, which includes an upper mold and a lower mold connected by guide pillars. The upper mold includes a top plate, an upper template, and an upper mold base. The lower mold includes a bottom plate, two push plates, two support plates, and a lower mold base. An upper mold core is bolted to the middle of the bottom end of the upper mold base, and a lower mold core is bolted to the middle of the upper end of the lower mold base. A driving mechanism is provided inside the bottom end of the upper mold base and at both ends of the upper mold core. A sliding mechanism is provided inside the upper end of the lower mold base and between both ends of the lower mold core. The top end of the sliding mechanism extends into the bottom end of the upper mold base, and the driving mechanism and the sliding mechanism on the same side cooperate with each other.

[0006] Furthermore, the lower mold core has a mating groove at the top center, and both ends of the lower mold core have lower mold cavities with a depth greater than the mating groove. The lower mold cavity is connected to the mating groove. A forming plate is integrally formed on the inner bottom wall of the mating groove and at the center of one end near the lower mold cavity. An upper forming part is provided in the center of the lower mold cavity, and a forming hole is provided in the center of the upper forming part.

[0007] Furthermore, both of the aforementioned drive mechanisms include a mounting block, which is bolted to the inside of the upper mold base and close to the side of the upper mold core. A slanted rod is inserted into the middle of the mounting block, and a slanted plate is provided in the middle of the side of the mounting block away from the upper mold core. The slanted plate is bolted to the inside of the upper mold core, and a first inclined surface is provided at the bottom end of the slanted plate close to the mounting block. The centerline of the slanted rod is parallel to the centerline of the first inclined surface.

[0008] Furthermore, both of the sliding mechanisms include two L-shaped limiting seats. The two L-shaped limiting seats on the same side are respectively bolted to the inside of the lower mold base and close to the lower mold core. A movable plate is slidably connected between the two L-shaped limiting seats on the same side. A second inclined surface is provided on the side of the movable plate away from the lower mold core. The second inclined surface is slidably connected to the first inclined surface. An inclined hole that cooperates with the inclined rod is provided at the top center of the movable plate, and the bottom end of the inclined rod is slidably connected in the inclined hole.

[0009] Furthermore, a mounting plate is bolted to the middle of the side of the movable plate near the lower mold core. The two ends of the mounting plate are provided with opposing second sliding plates, and a plurality of first sliding plates are provided in the middle of the mounting plate and between the two second sliding plates.

[0010] Furthermore, the cross-section of the end of the first positioning plate away from the mounting plate is an isosceles trapezoid, and the cross-section of the end of the second positioning plate away from the mounting plate is a right-angled trapezoid, with its right-angled hypotenuse close to the side of the first positioning plate.

[0011] Furthermore, the first positioning plate has dovetail blocks on both sides of the end away from the mounting plate, and the second positioning plate has dovetail blocks on the side of the end away from the mounting plate and close to the first positioning plate. Each dovetail block is slidably connected to a pressure head forming plate with a dovetail groove.

[0012] Furthermore, the pressure head forming plate is rectangular in shape, and each of the two adjacent pressure head forming plates has a pressure head forming groove on the upper end of the side that is close to each other. The two pressure head forming grooves are joined together to form a pressure head forming cavity.

[0013] Furthermore, both ends of the bottom of the lower mold core are provided with grooves that are adapted to the first sliding plate. The mounting plate is located below the grooves. The inner top wall of the grooves and the middle part of the lower mold base are provided with guide grooves that cooperate with the pressure head forming plate.

[0014] Furthermore, one side of the inner wall of the groove is integrally formed with multiple triangular guide portions, the two sides of the triangular guide portions are slidably connected between two adjacent dovetail blocks, and the guide groove passes through the middle of the triangular guide portions.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a driving mechanism and a sliding mechanism that cooperate with each other at both ends of the upper mold core and the lower mold core, respectively. The driving mechanism drives the sliding mechanism to move. A first sliding plate and a second sliding plate are mounted on a movable plate via a mounting plate. The movable plate can reciprocate under the drive of the driving mechanism, causing the first and second sliding plates to reciprocate and move towards or away from each other via dovetail blocks. This allows the mold forming groove of the mold to be closed and demolded, facilitating the demolding of the mold head a. This sliding structure is compact, facilitates multiple production runs from a single mold, improves production efficiency, and greatly reduces the size of the mold, thereby reducing the weight of the machine.

[0030] Please refer to Figures 1-7. A space-saving sliding structure includes a mold body 1, which comprises an upper mold 1 and a lower mold 2 connected by guide pillars. The upper mold 1 includes a top plate 101, an upper template 102, and an upper mold base 103. The lower mold 2 includes a bottom plate 201, two push plates 202, two support plates, and a lower mold base 203. An upper mold core 3 is bolted to the middle of the bottom end of the upper mold base 103, and a lower mold core 4 is bolted to the middle of the upper end of the lower mold base 203. A drive mechanism is provided inside the bottom end of the upper mold base 103 and at both ends of the upper mold core 3. A drive mechanism is provided inside the upper end of the lower mold base 203 and at both ends of the upper mold core 3. A sliding mechanism is provided between both ends of the lower mold core 4. The top of the sliding mechanism extends to the bottom of the upper mold base 103 and cooperates with the driving mechanism on the same side. The top plate 101, the upper template 102 and the upper mold base 103 are connected by bolts, and the bottom plate 201, the two push plates 202, the two support plates and the lower mold base 203 are connected by screws. The upper mold 1 and the lower mold 2 are connected in the existing structure. There are two ejector pins at one end between the two push plates 202, and the top of the ejector pins penetrates the lower mold base 203 and the lower mold core and is flush with the lower mold cavity 402, which is used to eject the product.

[0031] During production, the injection molding machine can drive the lower mold 2 and the upper mold 1 to close the mold. During the mold closing process, the lower mold base 203 drives the lower mold base 203 and the upper mold base 103 to close the mold, and can drive the lower mold core 4 and the upper mold core 3 to close the mold. At the same time, the sliding mechanism can contact the driving mechanism, so that the driving mechanism drives the sliding mechanism into the lower mold core 4. When the mold is fully closed, the sliding mechanism, the lower mold 4 and the upper mold 1 cooperate to form the cavity structure of the part.

[0032] Specifically, as shown in Figures 3, 4, and 5, the lower mold core 4 has a mating groove 401 at the top center. Both ends of the lower mold core 4 have lower mold cavities 402 with a depth greater than the mating groove 401. The lower mold cavities 402 are connected to the mating groove 401. A forming plate 403 is integrally formed on the inner bottom wall of the mating groove 401 and at the center of one end near the lower mold cavity 402. An upper forming part 404 is provided in the center of the lower mold cavity 402, and a forming hole 405 is provided in the center of the upper forming part 404. The bottom end of the upper mold core 3 has a boss that mates with the mating groove 401 and an upper mold cavity that mates with the lower mold cavity 402. Both ends of the boss have forming grooves that mate with the forming plate 403. A forming punch that mates with the upper forming part 404 is provided in the upper mold cavity. The upper forming part 404 and the forming punch mate to form an upper arc surface a structure. The forming hole 405 can form a support column b structure.

[0033] Specifically, as shown in Figure 3, both drive mechanisms include mounting blocks 7. Mounting blocks 7 are bolted to the inside of the upper mold base 103 and close to the side of the upper mold core 3. An inclined rod 8 is inserted in the middle of the mounting block 7. An inclined plate 9 is provided in the middle of the side of the mounting block 7 away from the upper mold core 3. The inclined plate 9 is bolted to the inside of the upper mold core 3. The bottom end of the inclined plate 9 is provided with a first inclined surface on the side close to the mounting block 7. The center line of the inclined rod 8 is parallel to the center line of the first inclined surface. The top of the lower mold base 203 is provided with a corresponding clearance groove at the position corresponding to the inclined rod 8 and the inclined plate 9.

[0034] Specifically, as shown in Figures 4 and 5, both sliding mechanisms include two L-shaped limiting seats 5. The two L-shaped limiting seats 5 on the same side are respectively bolted to the inside of the lower mold base 203 and close to the lower mold core 4. A movable plate 6 is slidably connected between the two L-shaped limiting seats 5 on the same side. The movable plate 6 has a second inclined surface on the side away from the lower mold core 4. The second inclined surface is slidably connected to the first inclined surface. The top center of the movable plate 6 has an inclined hole that cooperates with the inclined rod 8, and the bottom end of the inclined rod 8 is slidably connected in the inclined hole. When the mold is closed, the lower mold base 203 drives the L-shaped limiting seats 5 and the movable plate 6 to move closer to the inclined rod 8 and the inclined plate 9. The inclined rod 8 can enter the inclined hole and drive the movable plate 6 to slide in the L-shaped limiting seat 5. At the same time, the movable plate 6 can move closer to the lower mold core 4. Conversely, when the mold is opened, the inclined rod 8 can gradually disengage from the inclined hole and drive the movable plate 6 away from the lower mold core 4.

[0035] Specifically, as shown in Figures 3 and 5, a mounting plate 601 is bolted to the middle of the side of the movable plate 6 near the lower mold core 4. The two ends of the mounting plate 601 are provided with opposing second sliding plates 603. In the middle of the mounting plate 601 and between the two second sliding plates 603, there are multiple first sliding plates 602. When the movable plate 6 moves closer to or away from the lower mold core 4, it can drive the first sliding plates 602 and the second sliding plates 603 to move at the bottom end of the lower mold core 4 through the mounting plate 601.

[0036] Specifically, as shown in Figure 5, the cross-section of the first row plate 602 away from the mounting plate 601 is an isosceles trapezoid, and the cross-section of the second row plate 603 away from the mounting plate 601 is a right-angled trapezoid, with its right-angled hypotenuse close to the side of the first row plate 602; the two second row plates 603 and the adjacent first row plates 602, as well as the middle adjacent first row plates 602, form an installation space, which not only allows for multiple molds to be produced from one mold, but also greatly reduces the space occupied by the row mechanism.

[0037] Specifically, as shown in Figure 5, the first row plate 602 has dovetail blocks 604 on both sides of the end away from the mounting plate 601, and the second row plate 603 has dovetail blocks 604 on the end away from the mounting plate 601 and the side close to the first row plate 602. Each dovetail block 604 is slidably connected to a pressure head forming plate 605 with a dovetail groove. When the movable plate 6 moves, the first row plate 602 and the second row plate 603 can be moved by the mounting plate 601. At the same time, when the first row plate 602 and the second row plate 603 move, the pressure head forming plates 605 on them can move closer to each other or further away from each other by the dovetail blocks 604 on them.

[0038] Specifically, as shown in Figure 5, the pressure head forming plate 605 is rectangular in shape. The upper end of the side of two adjacent pressure head forming plates 605 that are close to each other is provided with a pressure head forming groove 606. The two pressure head forming grooves 606 are joined together to form a pressure head forming cavity. When the adjacent pressure head forming plates 605 are far apart, the two pressure head forming grooves 606 separate from each other, so that the two release the pressure head a formed in the pressure head forming cavity. Then, the ejector pin pushes the pressure head a upward, so that the part can be demolded.

[0039] Specifically, as shown in Figures 3 and 7, both ends of the bottom of the lower mold core 4 are provided with grooves 406 that are adapted to the first sliding plate 602. The mounting plate 601 is located below the grooves 406. The inner top wall of the grooves 406 and the middle part of the lower mold base 203 are provided with guide grooves that cooperate with the pressure head forming plate 605. The top and bottom ends of the pressure head forming plate 605 are slidably connected in the corresponding guide grooves, and the pressure head forming cavity corresponds to the forming hole 405. The grooves 406 can form a clearance between the first sliding plate 602 and the second sliding plate 603, so that the first sliding plate 602 and the second sliding plate 603 can move in the grooves 406 without interference. At the same time, the guide grooves can limit and guide the pressure head forming plate 605, so that when the first sliding plate 602 and the second sliding plate 603 move, the dovetail block 604 can drive the pressure head forming plate 605 to move in the guide groove, improving the stability of the pressure head a demolding.

[0040] Specifically, as shown in Figure 7, a plurality of triangular guide portions 407 are integrally formed on one side of the inner wall of the groove 406. The two sides of the triangular guide portion 407 are slidably connected between two adjacent dovetail blocks 604, and the guide groove passes through the middle of the triangular guide portion 407. The triangular guide portion 407 can guide and limit the dovetail block 604 to ensure the stability of the movement of the dovetail block 604.

[0041] In summary, compared with the prior art, this mold with a base has at least the following beneficial effects: This invention sets a driving mechanism and a sliding mechanism that cooperate with each other at both ends of the upper mold core 3 and the lower mold core 4, respectively. The driving mechanism can drive the sliding mechanism to move. A first sliding plate 602 and a second sliding plate 603 are mounted on the movable plate 6 via a mounting plate 601. The movable plate 6 can reciprocate under the drive of the driving mechanism, causing the first sliding plate 602 and the second sliding plate 603 to reciprocate and move, and through the dovetail block 604, drive the adjacent pressure head forming plates 605 to move closer or further apart, thereby enabling the pressure head forming groove 606 to close and release the mold, facilitating the demolding of the pressure head a. Simultaneously, this sliding structure is compact, allowing for rapid multi-mold production, improving production efficiency, and significantly reducing the size of the mold, thus reducing the weight of the machine.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
