Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of palm-shaped model manufacturing, in particular to a die casting die. BACKGROUND

[0002] In the prior art, the preparation of a palm-shaped model usually needs to use a palm-shaped inner row position assembly (usually drivenly connected with a core-pulling module) to assist the casting forming of the palm-shaped model. Accordingly, the installation of the palm-shaped inner row position assembly is involved in the preparation process of the palm-shaped model. However, the existing die casting die has an unreasonable structure design, so that the installation space of the palm-shaped inner row position assembly (usually assembled by a main row position and long and short row position inserts located on both sides of the main row position) is relatively limited, which leads to the problem of inconvenient assembly of the palm-shaped inner row position assembly in the die casting die, and further affects the production efficiency of the palm-shaped model. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to provide a die casting die which has the advantage of facilitating the assembly of a palm-shaped inner row position assembly, thereby helping to improve the production efficiency of the palm-shaped model.

The movable die is oppositely distributed with the fixed die, and the movable die comprises a movable die frame and a movable die core. The movable die frame comprises a movable die front mold plate and a movable die rear mold plate which are overlapped and distributed, and the movable die front mold plate is located on the side close to the fixed die. The movable die core comprises a movable die inner mold core and a movable die outer mold core which is peripherally arranged around the movable die inner mold core. The movable die outer mold core is embedded in the movable die front mold plate and can move synchronously with the movable die front mold plate.

The movable die inner mold core penetrates through the movable die front mold plate and the movable die outer mold core, and the movable die inner mold core has a movable die cavity. The driving module is used to be drivingly connected with the movable die plate of a die casting machine, and the driving module is drivingly connected with the movable die front mold plate and the movable die rear mold plate, so as to make the movable die front mold plate and the movable die rear mold plate move relatively to make the movable die present an open die state and a closed die state. When the movable die is in the open die state, there is a height difference between the movable die inner mold core and the movable die outer mold core, so as to install the palm-shaped inner row position assembly.

The open mold ejector pin 320 comprises a first open mold ejector pin 321, a second open mold ejector pin 322 and a third open mold ejector pin 323; the upper end of the first open mold ejector pin 321 penetrates the first ejector pin plate 311 and the first ejector pin over-plate 312 and abuts against the second ejector pin plate 313, and the other end is drivingly connected with the die casting machine movable mold plate; the upper end of the second open mold ejector pin 322 penetrates the first ejector pin over-plate 312, the second ejector pin plate 313, the second ejector pin over-plate 314 and the movable mold back plate 212 and abuts against the movable mold front plate 211, and the other end abuts against the first ejector pin plate 311; the lower end of the third open mold ejector pin 323 penetrates the second ejector pin over-plate 314 and abuts against the second ejector pin plate 313, and the upper end of the third open mold ejector pin 323 penetrates the movable mold back plate 212 and can selectively protrude the movable mold front plate 211. The lower end of the close mold return pin 330 penetrates the movable mold front plate 211, the movable mold back plate 212 and the second ejector pin over-plate 314 and abuts against the second ejector pin plate 313, and the other end can selectively protrude the movable mold front plate 211.In the mold opening process, the movable mold front plate 211 can be driven by the movable mold plate of the die casting machine, the first mold opening pin 321 and the second mold opening pin 322 to move towards the side of the fixed mold 100, so that the movable mold 200 moves to the mold opening state, at this time, the movable mold inner core 221 and the movable mold outer core 222 have a height difference, the locking assembly 315 is in the disengaged state, the third mold opening pin 323 protrudes from the movable mold front plate 211 and abuts against the palm-shaped model, the mold closing return pin 330 protrudes from the movable mold front plate 211, and the top end of the mold closing return pin 330 is higher than the top end of the third mold opening pin 323; in the mold closing process, the movable mold 200 can be driven by the movable mold plate of the die casting machine to move towards the side of the fixed mold 100, so that the upper end of the mold closing return pin 330 abuts against the fixed mold 100, and then the fixed mold 100 can apply a counter thrust force to the movable mold front plate 211 through the mold closing return pin 330 to drive the movable mold front plate 211 to move towards the movable mold rear plate 212, so that the movable mold 200 moves to the mold closing state, at this time, the movable mold outer core 222 surrounds the periphery of the movable mold inner core 221 and the inner mold faces of the two are flush, and the locking assembly 315 is in the locked state.

[0055] In this embodiment, the driving module 300 is arranged in a specific form, which has the advantages of reasonable structure layout, so that the die casting mold 10 has the characteristics of compact structure, convenient operation and high movement stability.

[0056] It should be noted that the form in which the third mold opening pin 323 protrudes from the movable mold front plate 211 and abuts against the palm-shaped model is not limited, for example, it can directly abut against the palm-shaped model, or indirectly abut against the palm-shaped model (i.e., abut against the ladle formed integrally with the palm-shaped model), and in the embodiments of the present application, the indirect abutment against the palm-shaped model is taken as an example.

[0057] Referring to Figure 4 and Figure 7 , in order to better understand the technical solutions, the relative positional relationship between the ladle groove 2221 (most part of the ladle formed in the die casting process) and the flow channel 2222 (small part of the ladle formed in the die casting process) is exemplarily described in combination with the exhaust valve 2113 (a structure commonly used in the die casting mold 10 for exhaust during the die casting process).

[0058] Referring to Figure 4 and Figure 7 , as an example, the movable mold outer core 222 is provided with the ladle groove 2221 and the flow channel 2222 corresponding to the palm-shaped model on the side close to the fixed mold 100, the ladle groove 2221 and the flow channel 2222 are communicated and communicated with the exhaust groove on the exhaust valve 2113, and the exhaust valve 2113 is embedded on the side of the movable mold front plate 211 close to the fixed mold 100.

[0059] It should be noted that the exhaust groove on the exhaust valve 2113 can not only be used for exhaust during the die casting process, but also can effectively prevent the slurry from leaking, so the exhaust groove may also form a part of the slag ladle during the die casting process. Therefore, in order to more easily disassemble the palm-shaped model during mold opening, a third mold opening pin 323 can be further added, that is, the third mold opening pin 323 is also arranged at the corresponding area of the exhaust valve 2113 (for details, please refer to Figure 7 ), so that after the mold is opened, the third mold opening pin 323 can also protrude from the exhaust valve 2113 and abut against the slag ladle therein, thereby assisting in disassembling the palm-shaped model. It should be noted that the relative position relationship between the locking assembly 315 and the top plate is not limited, as long as the locking assembly 315 can realize the corresponding function, for example, the top plate is a cuboid, and both ends of the length direction of the top plate are provided with the locking assembly 315.

[0060] It should be noted that the number of various pin elements is not limited and can be adaptively adjusted according to actual needs, for example, the number of each pin element is 2-8.

[0061] Referring to Figure 8 and Figure 9 , as an example, the locking assembly 315 includes a bearing seat 3151, a support column 3152, a spring block 3153, a limiting block 3154, and a recovery cone 3155. The support column 3152 is protruded on the bearing seat 3151 and extends towards one side of the fixed mold 100. The first pin plate 311, the first pin over plate 312, the second pin plate 313, and the second pin over plate 314 are sequentially carried on the circumferential edge of the bearing seat 3151 and are all movably connected with the support column 3152. A through hole penetrating through the support column 3152 is horizontally formed in the side wall of the support column 3152. The spring block 3153 detachably blocks one end of the through hole. The limiting block 3154 is arranged in the through hole. An elastic element is arranged between the limiting block 3154 and the spring block 3153, so that the limiting block 3154 can be popped out from the other end of the through hole. A channel communicating with the through hole is formed in the top of the support column 3152. Part of the recovery cone 3155 is accommodated in the channel. The limiting block 3154 is provided with a plug-in groove for plug-in cooperation with the bottom of the recovery cone 3155. The limiting block 3154 can be switched between the popped-out state and the retracted state. The recovery cone 3155 inserted into the plug-in groove can make the locking assembly 315 in the disengaged state. At this time, the limiting block 3154 is in the retracted state, and the elastic element is in the compressed state. The recovery cone 3155 disengaged from the plug-in groove can make the locking assembly 315 in the locked state. At this time, the limiting block 3154 is in the popped-out state, and the bottom of the limiting block 3154 abuts against the top of the second pin plate 313, so that the first pin plate 311 is locked together with the first pin over plate 312 and the second pin plate 313.

[0062] In this embodiment, the locking assembly 315 comprises a bearing seat 3151, a support column 3152, a spring block 3153, a limiting block 3154 and a recovery cone 3155. Specifically, the recovery cone 3155 is inserted into the insertion slot, so that the locking assembly 315 is in a disengaged state, at this time, the limiting block 3154 is in a retracted state, and the elastic member is in a compressed state. The recovery cone 3155 is separated from the insertion slot, so that the locking assembly 315 is in a locked state, at this time, the limiting block 3154 is in a pop-up state, and the bottom of the limiting block 3154 abuts against the top of the second needle plate 313, so that the first needle plate 311 is locked together with the first needle plate 312 and the second needle plate 313. The locking assembly 315 in this operation mode has the advantages of simple structure and smooth state switching.

[0063] Referring to Figure 10 As an example, the limiting block 3154 comprises a fixed portion 3154a and an insertion portion 3154b, the size of the fixed portion 3154a is larger than the size of the insertion portion 3154b, so that the fixed portion 3154a is limited in the through hole, and the insertion portion 3154b can be selectively separated from the through hole to abut against the top of the second needle plate 313.

[0064] In this embodiment, the limiting block 3154 comprises a fixed portion 3154a and an insertion portion 3154b, and the size of the fixed portion 3154a is larger than the size of the insertion portion 3154b, so that the fixed portion 3154a is limited in the through hole, so that the limiting block 3154 cannot be completely separated from the through hole, thereby facilitating the adaptation and insertion cooperation of the bottom of the recovery cone 3155.

[0065] Referring to Figure 4 and Figure 11As an example, the core-pulling module 400 includes a fixed frame 410a and a core-pulling assembly 410b, the fixed frame 410a is fixedly connected with the movable die front plate 211, the core-pulling assembly 410b is movably connected with the fixed frame 410a, one end of the core-pulling assembly 410b is connected with the main row position 510, the core-pulling assembly 410b can form a mold cavity for casting a palm-shaped model with the fixed mold cavity and the movable mold cavity after the mold is closed, and the main row position 510 can be taken out from the palm-shaped model through the core-pulling assembly 410b after the mold is opened; wherein the size of the palm-shaped mold cavity in the extension direction of the main row position (510) is 110-280 mm, for example but not limited to any one of the point values of 110 mm, 150 mm, 200 mm, 230 mm, 260 mm and 280 mm or a range value between any two of them; the die casting mold 10 further includes a left row position 420 and a right row position 430 located on both sides of the core-pulling module 400, the movable die front plate 211 is provided with a left row position recess 2111 and a right row position recess 2112 corresponding to the left row position fixed seat in the left row position 420 and the right row position fixed seat in the right row position 430, respectively, in the palm-shaped inner row position assembly 500, the long row position insert 520 and the short row position insert 530 located on both sides of the main row position 510 correspond to the left row position 420 and the right row position 430, respectively, and in the extension direction of the main row position 510, the size of the left row position recess 2111 is not less than the length of the long row position insert 520, and the size of the right row position recess 2112 is not less than the length of the short row position insert 530; wherein the length of the long row position insert 520 is 100-250 mm, for example but not limited to any one of the point values of 100 mm, 150 mm, 200 mm and 250 mm or a range value between any two of them; the length of the short row position insert 530 is 80-220 mm, for example but not limited to any one of the point values of 80 mm, 100 mm, 150 mm, 200 mm and 220 mm or a range value between any two of them.

[0066] In this embodiment, the die casting mold 10 further includes a left row position 420 and a right row position 430 located on both sides of the core-pulling module 400, the movable die front plate 211 is provided with a left row position recess 2111 and a right row position recess 2112 corresponding to the left row position fixed seat in the left row position 420 and the right row position fixed seat in the right row position 430, respectively, and in the extension direction of the main row position 510, the size of the left row position recess 2111 is not less than the length of the long row position insert 520, and the size of the right row position recess 2112 is not less than the length of the short row position insert 530, in the mold opening state, a larger assembly space can be provided for the assembly of the main row position 510 and the long and short row position inserts 530, thereby being more conducive to the assembly of the palm-shaped inner row position assembly 500; at the same time, the arrangement of the left row position 420 and the right row position 430 also helps to improve the problem that the palm-shaped mold is prone to deformation during the core-pulling process, thereby obtaining a high-quality palm-shaped model.

[0067] It should be noted that the size of the palm-shaped cavity in the extension direction of the main row position (510) corresponds to the actual length of the prepared palm-shaped model.

[0068] It should be noted that the setting form of the core pulling module 400, the left row position 420 and the right row position 430 in the embodiments of the present application is not limited, and can be set according to conventional selection in the art as long as it has the corresponding function.

[0069] Referring to Figure 12 and Figure 13 , as an example, the two side surfaces of the main row position 510 are provided with limiting clamping columns 511 extending in the axial direction of the main row position 510, and the long row position insert 520 and the short row position insert 530 are both provided with limiting clamping grooves 540 (the position of the limiting clamping groove 540 is described in combination with the structure of the long row position insert 520 in the embodiments of the present application) which are matched with the corresponding limiting clamping columns 511.

[0070] In this embodiment, limiting clamping columns 511 are additionally provided on both sides of the main row position 510, and corresponding limiting clamping grooves 540 are respectively provided in the corresponding regions of the long row position insert 520 and the short row position insert 530. Through the matching mode, the problem that the long row position insert 520 and the short row position insert 530 are pushed open when the aluminum material is filled under high pressure, which leads to the problem of row position clamping and batch edge running and makes it impossible to assemble the inserts subsequently, can be effectively solved.

[0071] It should be noted that the shape of the limiting clamping column 511 is not limited, and can be adaptively adjusted according to actual needs, as long as it can be matched with the long row position insert 520 and the short row position insert 530, for example, it can be circular, oval, prismatic or square, etc.

[0072] It should be noted that the size of the limiting clamping column 511 is not limited, and can be adaptively adjusted according to actual needs. Taking the circular limiting clamping column 511 as an example, the maximum outer diameter of the limiting clamping column 511 is 0.5-6mm, and the axial length of the limiting clamping column 511 is 1-100mm.

[0073] Referring to Figure 12 , Figure 13 and Figure 14 , as an example, two limiting clamping columns 511 are provided between the main row position 510 and the long row position insert 520, and between the main row position 510 and the short row position insert 530.

[0074] In this embodiment, two limiting clamping columns 511 are arranged between the main row position 510 and each insert, that is, two clamping and matching areas are provided, which can improve the assembly stability between the main row position 510 and the corresponding insert, thereby better solving the problem that the long row position insert 520 and the short row position insert 530 are pushed open during high-pressure filling of aluminum material, causing clamping of the row position and running of the batch edge, thereby causing subsequent assembly of the insert to fail.

[0075] In other possible embodiments, three or four limiting clamping columns 511 can be arranged between the main row position 510 and the long row position insert 520, and between the main row position 510 and the short row position insert 530.

[0076] Referring to Figure 13 For example, the wall thickness of the region of the long row position insert 520 and the short row position insert 530 provided with the limiting clamping slot 540 is 0.3-6 mm, such as but not limited to any one of 0.3 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm, or a range value between any two of them.

[0077] In this embodiment, the wall thickness of the region of the long row position insert 520 and the short row position insert 530 provided with the limiting clamping slot 540 is limited within a certain range, so that the row position insert is not easily damaged or even cracked during use, thereby having a longer service life; at the same time, it also has the advantage of facilitating assembly of the palm-shaped inner row position assembly 500.

[0078] Referring to Figures 12 to 15 For example, the limiting clamping column 511 has an insertion end 5111 and a closed end 5112 that are oppositely distributed, the insertion end 5111 is located on the side away from the driving part of the main row position 510 (i.e., the side close to the core pulling assembly 410b), and the end corresponding to the closed end 5112 of the long row position insert 520 and the short row position insert 530 is respectively inserted and matched with the corresponding region of the main row position 510, so that the long row position insert 520 and the short row position insert 530 are respectively locked together with the main row position 510.

[0079] In this embodiment, the end corresponding to the closed end 5112 of the long row position insert 520 and the short row position insert 530 is respectively inserted and matched with the corresponding region of the main row position 510, so that the long row position insert 520 and the short row position insert 530 are respectively locked together with the main row position 510, which can better solve the problem that the long row position insert 520 and the short row position insert 530 are pushed open during high-pressure filling of aluminum material, causing clamping of the row position and running of the batch edge, thereby causing subsequent assembly of the insert to fail.

[0080] Referring to Figure 14 and Figure 15As an example, the main row position 510 is provided with a limiting groove 512 corresponding to the closed end 5112, which matches the end of the long row position insert 520 and the end of the short row position insert 530.

[0081] In this embodiment, the main row position 510 is provided with a limiting groove 512 corresponding to the closed end 5112, which matches the end of the long row position insert 520 and the end of the short row position insert 530. In this way, plug-in cooperation is achieved, and the structure is reasonably designed.

[0082] As an example, the depth of the limiting groove 512 is 0.2-10mm, such as but not limited to any one of 0.2mm, 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm, or a range value between any two of them.

[0083] In this embodiment, the depth of the limiting groove 512 is limited within a certain range, so that the region of the main row position 510 corresponding to the closed end 5112 can be more closely and stably combined with the end of the long row position insert 520 and the end of the short row position insert 530.

[0084] It should be noted that the structure or functional units not specifically described or limited in the die casting mold 10 can be set according to the conventional selection in the art.

[0085] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
