Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a mold clamping force strengthening mechanism and a mold. Background Art

[0002] Die casting is a metal casting process, which is characterized by applying high pressure to molten metal by using the inner cavity of a mold; injection molding, also known as injection molding, is a molding method that combines injection and molding. In these two processes, the die-casting or injection molds used will generate a mold expansion force due to the filling of materials inside the mold. When the mold expansion force exceeds the mold clamping force of the machine, the mold will be opened. At this time, a larger machine needs to be replaced to meet the requirement of the mold clamping force, but it is very inconvenient for processing and will increase the production cost of the enterprise. Although a mold clamping mechanism can be used to strengthen the mold clamping force of the machine to solve the above problems, the mold clamping force provided by the existing mold clamping mechanism is small, and the use effect is not good, and it still cannot well solve the problems faced by the enterprise. Therefore, a mechanism that can provide a larger mold clamping force is needed. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, one of the purposes of the utility model is to provide a mold clamping force strengthening mechanism, which uses a driving device and cooperates with inserts inserted into the mold to lock the upper and lower templates of the mold, so as to supplement and strengthen the insufficient mold clamping force of the machine. This mechanism can provide sufficient mold clamping force for a die-casting machine or an injection molding machine, so that a machine with a smaller mold clamping force can be used during product processing, and there is no need to replace the machine, thus saving costs.

[0004] The utility model provides a mold clamping force strengthening mechanism, which includes inserts and a driving device. The inserts include a connecting piece, a fixing piece and a locking piece;

[0005] The connecting piece is inserted into the A plate and the B plate of the mold, and two connecting holes adapted to the fixing piece and the locking piece are opened. A first socket is arranged on the A plate, and a second socket is arranged on the B plate. The first socket and the second socket respectively correspond to one of the connecting holes; the fixing piece penetrates through the first socket and is inserted into the connecting hole, and the locking piece penetrates through the second socket and is inserted into the connecting hole;

[0006] The driving device is located on one side of the B plate and is used to drive the locking piece to insert and pull out the second socket;

[0007] The locking member is fixed on the driving rod of the driving device. In this mechanism, the A plate is the moving template of the mold, and the B plate is the fixed template of the mold. The connecting member serves to connect the A plate and the B plate. One end of it is located in the A plate, and the opposite end is located in the B plate. By inserting the fixing member into the corresponding connecting hole and clamping it on the first socket of the A plate, the connection to the A plate is achieved indirectly, and the fixing member clamps one end of it in the A plate, preventing it from falling off. After inserting the opposite end of the connecting member into the B plate and fully closing the mold, another connecting hole on the connecting member is aligned with the second socket on the B plate for the subsequent entry of the locking member. Subsequently, under the action of the driving device, one end of the locking member is inserted into the second socket and clamped in the corresponding connecting hole. Combining the clamping and connecting effects of the connecting member and the fixing member, the A plate and the B plate of the mold are tightly combined, thereby enhancing the clamping force of the machine.

[0008] In a preferred technical solution of the present utility model, the fixing member is provided with a fixing plate for fixing the fixing member on the A plate. An adhesive can be attached to this fixing plate. With the assistance of this fixing plate, when the fixing member is clamped in the first socket, the fixing plate at one end of it is fixed at the first socket of the A plate, further ensuring the reliability of the connection between the connecting member and the A plate.

[0009] In a preferred technical solution of the present utility model, an installation seat with an opening is sleeved on the driving rod. The installation seat is fixed on the B plate, and the opening corresponds to the second socket; the driving device is fixed at one end of the installation seat relative to the opening, the locking member is fixed at the end of the driving rod and is located at the opening, and the locking member enters and exits the second socket through the opening. The end of the installation seat with the opening is located at the second socket of the B plate, and the two protruding ends at the opening are fixed on the opposite sides of the second socket, such as extending plate edges that can be fixed on the contact surface with the B plate and then using screws to fix, so that the opening and the second socket are aligned. The other end of the installation seat relative to the opening is fixed with the driving device, and the driving rod on the driving device passes through the installation seat, and the locking member is fixed at the end of the driving rod. In the subsequent use of the mold, the driving device does not need to be repeatedly installed, making production more efficient. In this way, when the driving device drives, it can easily make the locking member accurately aligned with the second socket, reducing the time for manual alignment and improving the alignment accuracy; on the other hand, the driving device is easily installed on this installation seat, and the design around this installation seat can facilitate the confirmation of the situation during a failure, and then promptly repair and replace.

[0010] In a preferred technical solution of the present utility model, a first mounting hole is provided at the top of the connecting member, and the connecting member is fixed to the A plate through the first mounting hole. The first mounting hole is a strip-shaped blind hole, and long-strip fixing components such as screws can be used to install the connecting member in the A plate. At the same time, strip-shaped fixing components can be pre-set in the A plate, and then fixing parts are used to connect the A plate and the connecting member, making the installation of the connecting member more convenient.

[0011] The second object of the present utility model is to provide a mold, including the A plate and the B plate, the A plate is located on the B plate, and the mold clamping force strengthening mechanism described in any one of the above is provided in the A plate and the B plate. This mold uses the mold clamping force strengthening mechanism described in any one of the above, has a large mold clamping force during mold closing processing, can be used with a machine with a relatively small mold clamping force, and greatly improves the usability, meeting the production requirements of different products by enterprises under relatively limited equipment conditions and reducing the procurement cost.

[0012] In a preferred technical solution of the present utility model, a receiving cavity for inserting the connecting member is provided between the A plate and the B plate, and a second mounting hole is provided at the top of the receiving cavity. The shape of the receiving cavity is the same as that of the connecting member, and its internal size is slightly larger than that of the connecting member, aiming to ensure that the connecting member does not move during product processing and ensure stability. The design of providing a second mounting hole at the top of the receiving cavity allows a fixing component to pass through the hole of the second mounting hole and fix one end of it to the top of the connecting member, facilitating the preliminary fixing of the connecting member before using the fixing part to fix it.

[0013] In a preferred technical solution of the present utility model, a wear-resistant plate is provided in the second socket and is fixed to the upper and lower surfaces of the second socket by screws. The wear-resistant plate is provided on the contact surface between the second socket and the locking member, protecting the second socket and the locking member during the insertion and extraction of the locking member, and avoiding the wear of the B plate and the locking member caused by long-term use.

[0014] In a preferred technical solution of the present utility model, a fixing groove is provided at the second socket, and the fixing plate is fixed in the fixing groove. The size of the fixing groove matches the fixing plate on the fixing part, and an installation hole channel is also provided in the fixing groove, and corresponding fixing holes are also provided on the fixing plate, so that the fixing plate can be easily installed in the fixing groove during the installation process, saving installation time, and this disassembly and assembly method is more convenient and practical than the bonding method.

[0015] The specific implementation process is as follows: One end of the connecting piece is inserted into the A plate of the mold. The connecting piece is provided with connecting holes corresponding to the fixing piece and the locking piece for insertion. The position of the upper connecting hole corresponds to the position of the first socket on the A plate. One end of the fixing piece passes through the first socket on the A plate and through the upper connecting hole, and the opposite end is fixedly connected to the A plate outside the connecting hole, realizing the fixation of the whole connecting piece and the fixing piece to the A plate. When the mold is closed, the opposite end of the connecting piece is inserted into the B plate. After the mold is fully closed, the position of the lower connecting hole corresponds to the position of the second socket on the B plate. At the same time, a locking piece is fixed on the driving rod of the driving device. Through the driving action of the driving device, one end of the locking piece passes through the second socket and enters the lower connecting hole, and the opposite end is connected to the driving rod and stays outside the connecting hole; when the mold is opened, the driving device drives the locking piece to be pulled out from the second socket, and then the subsequent separation of the templates can be carried out. In this way, the A plate and the B plate can be locked when the mold is closed and can be easily separated when the mold is opened.

[0016] The beneficial effects of the present utility model at least include:

[0017] A mold clamping force strengthening mechanism provided by the present utility model includes an insert and a driving device. The insert includes a connecting piece, a fixing piece and a locking piece. The connecting piece is inserted into the A plate and the B plate of the mold and is provided with two connecting holes adapted to the fixing piece and the locking piece. The A plate is provided with a first socket, and the B plate is provided with a second socket. The first socket and the second socket respectively correspond to one of the connecting holes; the fixing piece penetrates through the first socket and is inserted into the connecting hole, and the locking piece penetrates through the second socket and is inserted into the connecting hole; the driving device is located on one side of the B plate and is used to drive the locking piece to insert and pull out the second socket; the locking piece is fixed on the driving rod of the driving device. This mechanism uses the connecting piece and the fixing piece to be inserted into the A plate first, and then through the cooperation of the driving device and the locking piece to be inserted into the B plate after the mold is fully closed, and uses the interaction between the inserts to lock the A and B plates inside the mold. Its structure is stable, can provide sufficient mold clamping force for a die-casting machine or an injection molding machine, prevent the phenomenon that the mold is pushed open by the swelling force during the processing, and enable a machine with a smaller mold clamping force to be used during product processing without replacing the machine, thus saving costs.

[0030] Embodiment 1

[0031] Refer to Figures 1 to 3 As shown, the present application provides a clamping force strengthening mechanism, including an insert 1 and a driving device 2. The insert 1 includes a connecting member 11, a fixing member 12 and a locking member 13;

[0032] The connecting member 11 is inserted into the A plate 3 and the B plate 4 of the mold, and is provided with two connecting holes 111 adapted to the fixing member 12 and the locking member 13. A first socket 31 is provided on the A plate 3, and a second socket 41 is provided on the B plate 4. The first socket 31 and the second socket 41 respectively correspond to one of the connecting holes 111. The fixing member 12 passes through the first socket 31 and is inserted into the connecting hole 111, and the locking member 13 passes through the second socket 41 and is inserted into the connecting hole 111.

[0033] The driving device 2 is located on one side of the B plate 4 and is used to drive the locking member 13 to insert and remove the second socket 41.

[0034] The locking member 13 is fixed on the driving rod 21 of the driving device 2.

[0035] In the above-mentioned mold clamping force strengthening mechanism, the A plate 3 is the moving template of the mold, and the B plate 4 is the fixed template of the mold. The mechanism includes a connecting member 11 and a fixing member 12. One end of the connecting member 11 is inserted into the A plate 3 of the mold, and the connecting member 11 is provided with a connecting hole 111 for the corresponding insertion of the fixing member 12 and the locking member 13. The position of the upper connecting hole 111 corresponds to the position of the first socket 31 on the A plate 3. One end of the fixing member 12 passes through the first socket 31 on the A plate 3 and passes through the upper connecting hole 111, and the opposite end is fixedly connected to the A plate 3 by a fixing screw outside the connecting hole 111, realizing the fixation of the connecting member 11 and the fixing member 12 as a whole to the A plate 3. When the mold is closed, the opposite end of the connecting member 11 is inserted into the B plate 4. After the mold is fully closed, the position of the lower connecting hole 111 corresponds to the position of the second socket 41 on the B plate 4. The locking member 13 is fixed on the driving rod 21 of the driving device 2. Through the driving action of the driving device 2, one end of the locking member 13 passes through the second socket 41 and the lower connecting hole 111, and the opposite end is connected to the driving rod 21 and stays outside the connecting hole 111. In this way, the A plate 3 and the B plate 4 are locked together to reach a stable state. During die casting or injection molding, the A and B plates 4 will be firmly locked together to prevent the mold from being pushed open by the internal pressure. This mechanism enables the corresponding process to increase a large mold clamping force after adding a few simple operations, and has a simple structure. The insert 1 is convenient to replace, which can improve the maintenance efficiency.

[0036] Further, the fixing member 12 is provided with a fixing plate 121 for fixing the fixing member 12 to the A plate 3. Specifically, the fixing plate 121 is provided at one end of the fixing member 12 and is close to the outer surface of the A plate 3 when the fixing member 12 is inserted. After being completely inserted, it abuts against the A plate 3. The fixing plate 121 is provided with two fixing holes around the corresponding connection hole 111 of the fixing member 12. A fastening screw can be used to pass through the two fixing holes to make the fixing plate 121 closely adhere to the surface of the A plate 3, thereby fixing the connecting member 11 and the A plate 3 by the fixing member 12. Further, a bottom hole can be opened at the position of the A plate 3 corresponding to the fixing hole, and a tap can be used for tapping threads, and then the fixing plate 121 can be more stably connected to the fixing member 12 and the A plate 3 through a screw, further fixing the connecting member 11. The fixing plate 121 connects the fixing member 12 to the A plate 3 and the connecting member 11, thereby preventing the connecting member 11 from falling off the A plate 3 and injuring people, and ensuring the safety of the staff.

[0037] Further, a mounting seat 5 with an opening 51 is sleeved on the driving rod 21. The mounting seat 5 is fixed to the B plate 4, and the opening 51 corresponds to the second socket 41; the driving device 2 is fixed to one end of the mounting seat 5 relative to the opening 51, and the locking member 13 is fixed to the end of the driving rod 21 and is located at the opening 51. The locking member 13 enters and exits the second socket 41 through the opening 51.

[0038] Specifically, one end of the mounting seat 5 has an opening 51. This end can be fixed to the surface of the B plate 4 by screws. The position of its opening 51 corresponds to the position of the second socket 41, that is, the central axis of the opening 51 is on the same axis as the central axes of the second socket 41 and the connection hole 111 below the connecting member 11; the driving device 2 is fixed to the other end relative to the opening 51, and the driving rod 21 extends through the mounting seat 5 from the driving device 2 and is on the central axis of the opening 51. The center of one end of the locking member 13 is fixed to the end of the driving rod 21 and is located at the position corresponding to the second socket 41 at the opening 51. The opening 51 is larger than the locking member 13. In this way, when the driving device 2 pushes and pulls the driving rod 21, the locking member 13 can move at the opening 51, and by using the corresponding relationship with the positions of the second socket 41 and the connection hole 111 below the connecting member 11, the other end of the locking member 13 opposite to it passes through the second socket 41 and the connecting member 11. The mounting seat 5 plays a role in fixing the driving device 2, and the driving device 2 can be conveniently replaced to adapt to different working conditions.

[0039] Further, a first mounting hole 112 is provided at the top of the connecting member 11, and it is fixed to the A plate 3 through the first mounting hole 112. Specifically, one end of the connecting member 11 provided with the first mounting hole 112 is inserted into the A plate 3, and a screw penetrates the A plate 3 on the upper surface of the A plate 3, and then the connecting member 11 and the A plate 3 are connected in cooperation with the first mounting hole 112. The first mounting hole 112 enables the connecting member 11 to be fixed first after being inserted into the A plate 3, and then the fixing member 12 is used for secondary fixing, improving the structural stability.

[0040] Embodiment 2

[0041] See Figure 4 and Figure 5 As shown, this embodiment provides a mold, which includes an A plate 3 and a B plate 4. The A plate 3 is located on the B plate 4, and a receiving cavity 6 for inserting the connecting member 11 is provided between the A plate 3 and the B plate 4, and a second mounting hole 61 is provided at the top of the receiving cavity 6. The A plate 3 and the B plate 4 are provided with the clamping force strengthening mechanism as described in any one of the above.

[0042] Specifically, the A plate 3 of this mold is located on the B plate 4 and combines with the B plate 4 to form the whole mold, and a cavity is formed in the A plate 3 and the B plate 4 for accommodating molten material to cool and form therein. A clamping force strengthening mechanism is provided on one side of the cavity, and a receiving cavity 6 is provided at the position where this mechanism is located. The connecting member 11 is inserted into the receiving cavity 6, one end of which is located in the A plate 3 and the opposite end is located in the B plate 4. The receiving cavity 6 is provided with a first socket 31 and a second socket 41 communicating with the outside at the position corresponding to the connecting hole 111, and a second mounting hole 61 is provided at the top of the receiving cavity 6. A screw can be provided in this second mounting hole 61, and the nut end of the screw faces upward and corresponds downward to the first mounting hole 112 for fixing the connecting member 11. This mold can supplement the lacking clamping force of the machine, thus achieving the effect of strengthening the clamping force. It is convenient to install during use, can save time and improve production efficiency.

[0043] Further, a wear-resistant plate 7 is provided in the second socket 41 and is fixed on the upper and lower surfaces of the second socket 41 by screws. Specifically, a plurality of screw holes through which screws pass are provided on the B plate 4, and the wear-resistant plate 7 is fixed by these screw holes using screws so that it is distributed on the top and bottom of the second socket 41. It can be understood that the wear-resistant plate 7 uses steel material with relatively high hardness, such as HRC46 - 52. The wear-resistant plate 7 can protect the material surface of the B plate 4 at the second socket 41 when the locking member 13 is inserted into the second socket 41, greatly reducing the loss during use, reducing the replacement frequency of the B plate 4, and reducing the expenditure cost.

[0044] Furthermore, a fixing groove 8 is provided at the second socket 41, and the fixing plate 121 is fixed in the fixing groove 8. Specifically, the fixing groove 8 is provided on the outer surface of the second socket 41 of the B plate 4. The fixing groove 8 is larger than the fixing plate 121 and is provided with a duct corresponding to the fixing hole, which facilitates installation.

[0045] Embodiment 3

[0046] Refer to Figure 6 and Figure 7 As shown, this embodiment provides a mold, which includes an A plate 3 and a B plate 4. The A plate 3 is located on the B plate 4. One side of the A plate 3 has a convex portion 9, and a concave groove 10 is correspondingly provided on the B plate 4. The convex portion 9 and the concave groove 10 are matched, and locking holes and locking grooves are provided at corresponding positions on the convex portion 9 and the concave groove 10. The mold further includes a driving device 2 and a locking member 13. The end of the driving rod 21 of the driving device 2 is installed with the locking member 13. The driving device 2 uses the driving rod 21 to drive one end of the locking member 13 to pass through the locking hole and enter the locking groove. In this way, the A plate 3 and the B plate 4 can be locked together to enhance the clamping force of the machine. The mold simplifies the structure and operation steps, shortens the processing time, and reduces the workload of the staff.

[0047] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
