Technical Field
[0001] This utility model relates to the field of casting molds, specifically to a casting mold for electronic connector housings. Background Technology
[0002] An electronic connector is a conductor device that bridges two conductors in a circuit, allowing current or signals to flow from one conductor to the other. It has an external housing for protection and to facilitate wiring. The electronic connector housing has an opening on one side and a cover on the opening side.
[0003] Electronic connector housings are generally made of metal and formed using casting molds. However, some existing electronic connector housings enlarge the side furthest from the opening to increase the wiring space for the cable (as shown in the attached image). Figure 1 As shown in the figure, this makes it difficult for the mold core to be removed from the small opening of the electronic connector housing after the existing casting mold has been cast. If the mold core is forcibly removed, it will easily damage the electronic connector housing. There is a technical problem that it is difficult to demold smoothly, and the production adaptability of the casting mold is low.
[0004] Therefore, the research objective of this utility model is to design a highly adaptable casting mold for electronic connector housings to address the problems existing in the prior art. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a casting mold for electronic connector housings, which can effectively solve the problems existing in the prior art.
[0006] The technical solution of this utility model is:
[0007] A casting mold for an electronic connector housing, comprising:
[0008] A first mold base and a second mold base are driven by a pressure mold driving device to close the mold in opposite directions. The first mold base and the second mold base are respectively provided with a first mold core and a second mold core forming a mold cavity between them. The opening on one side of the mold cavity is provided to form an opening side corresponding to the opening of the electronic connector housing. A pouring channel connecting the mold cavity and the outside is formed between the first mold base and the second mold base.
[0009] The demolding mechanism includes a drive seat with a first demolding part at one end, two drive members with a second demolding part at one end, and a demolding drive mechanism for driving the drive seat and drive members to move. The two second demolding parts are detachably disposed on both sides of the first demolding part and together form a mold core located in the mold cavity. The drive seat is blocked on the opening side. A molding cavity adapted to the electronic connector housing is formed between the outer wall of the mold core and the inner wall of the mold cavity. The demolding drive mechanism is used to drive the first demolding part and the two second demolding parts to move outward sequentially for demolding after the mold is opened.
[0010] Furthermore, the demolding drive mechanism includes a telescopic end connected to the drive seat and a movable seat movably arranged along the telescopic direction of the telescopic end. The other ends of the two drive members are movably connected to the movable seat. The two drive members are inclined and the distance between them gradually increases from one end to the other end. The drive seat is slidably sleeved on the two drive members and the first demolding part is located between the two drive members. When the telescopic end drives the drive seat to move towards the other end of the two drive members, the first demolding part disengages from the two second demolding parts, and the two drive members are pressed and drive the two second demolding parts to move towards each other until they abut each other. Then, the drive seat pulls the two drive members together to move until the two abutting second demolding parts disengage from the mold cavity.
[0011] Furthermore, the first mold base and the second mold base are distributed vertically. The demolding drive mechanism also includes a fixed base installed on the top of the second mold base, a hydraulic cylinder disposed on the fixed base and including the telescopic end, the movable seat is laterally slidably disposed in the fixed base, the telescopic end is laterally slidably disposed through the movable seat and connected to the drive seat, the drive seat is laterally slidably disposed in the fixed base and located between the opening side and the movable seat, the movable seat is recessed on the side near the drive seat and has a vertically extending sliding groove, and the other ends of the two drive members are vertically limited and slidably disposed in the sliding groove.
[0012] Furthermore, the two second demolding parts protrude outward from the opposite side away from the opening side to form an outward expansion part. The upper and lower sides of the drive seat are respectively provided with elongated sliding holes. The sidewalls of the two sliding holes extend to form a blocking part for blocking the opening side. The two drive members are configured as plates with wide surfaces facing each other and respectively adapted to be inclined through the two sliding holes. The included angle between the opposite sides of the two second demolding parts, the included angle between the upper and lower sides of the first demolding part, and the included angle between the two drive members are the same.
[0013] Furthermore, the two driving components and the two second demolding parts are provided with a plurality of limiting ribs on opposite sides, and the first demolding part and the sliding hole are provided with limiting grooves adapted to the plurality of limiting ribs. The groove width of the limiting grooves on the upper and lower sides gradually decreases in opposite directions, and the plurality of limiting ribs are respectively slidably embedded in the plurality of limiting grooves along the axial direction.
[0014] Furthermore, the fixed base is recessed with a plurality of first positioning grooves located on the outer side of the opening and second positioning grooves located on both sides. The bottom of the first mold base is provided with a plurality of first positioning posts and a plurality of second positioning posts corresponding to the plurality of first positioning grooves and second positioning grooves. The plurality of first positioning posts are used to be inserted into the plurality of first positioning grooves and limited to abutting against the outer side of the drive base when the mold is closed and the drive base is blocked on the opening side.
[0015] Furthermore, the second mold base and the second mold core are vertically provided with a plurality of first demolding channels and a plurality of second demolding channels corresponding to the pouring channel and the mold cavity, respectively. A first demolding rod and a second demolding rod, which are driven to extend upward by the upper push driving mechanism, are respectively inserted into the plurality of first demolding channels and the plurality of second demolding channels.
[0016] Furthermore, the first mold base and the second mold base each have a plurality of guide pillars and guide holes corresponding to each other.
[0017] Therefore, the beneficial effects of this utility model are:
[0018] 1. By adding a demolding mechanism, not only can the mold core be formed through the first and second demolding parts during mold closing, and a molding cavity for casting the electronic connector housing be formed between the outer wall of the mold core and the inner wall of the mold cavity, but also after mold opening, the first demolding part and the two second demolding parts can be driven outward sequentially by the demolding drive mechanism to demold. Thus, when the inner diameter of the inner end of the electronic connector formed in the molding cavity is larger than the opening side, the drive seat can be driven to move to the first demolding part to disengage from the two second demolding parts, freeing up demolding space, and then the two second demolding parts can be driven to move towards the opposite side and then outward to demold. This allows the casting mold to demold smoothly for different types of electronic connector housings without damaging the electronic connector housing, thus improving the adaptability of the casting mold.
[0019] 2. During the demolding process after mold opening, when the drive seat is driven to move towards the other end of the two drive components by the telescopic end of the demolding drive mechanism, the first demolding part disengages from the two second demolding parts, and the two drive components are pressed and driven to move towards each other until they abut each other. Then, the drive seat pulls the two drive components together to move to the two abutting second demolding parts to disengage from the mold cavity, thus completing the demolding action. The sequential movement, linkage movement, and opposite movement of the drive seat and the two drive components are realized by a single drive mechanism, which greatly reduces the drive cost, thereby reducing the overall production cost of the casting mold, reducing the space ratio of the casting mold, and improving its installation adaptability.
[0020] 3. The fixed seat improves the stability of the lateral movement of the drive seat and the lateral movement of the movable seat. The sliding groove improves the stability of the two drive components moving in opposite directions or in opposite directions, thereby improving the overall drive stability of the demolding drive mechanism.
[0021] 4. By setting the included angle between the opposite sides of the two second demolding parts, the included angle between the upper and lower sides of the first demolding part, and the included angle between the two driving parts to be the same, and by cooperating with a number of limiting ribs and a number of limiting grooves, the driving seat and the first demolding part are made to slide in a limited manner along the front and rear axial direction with the two driving parts and the two second demolding parts. Furthermore, by limiting the driving seat and the first demolding part to be embedded in the limiting groove, the upper and lower limits and the left and right limits can be generated between the driving seat and the first demolding part and the two driving parts and the two second demolding parts, so as to avoid displacement or slippage and improve the stability of the sliding fit between the two driving parts and the driving seat.

[0029] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:
[0030] refer to Figure 1-7 A casting mold for an electronic connector housing, comprising:
[0031] A first mold base 1 and a second mold base 2 are driven to close in opposite directions by a pressure mold driving device. The first mold base 1 and the second mold base 2 are respectively provided on opposite sides to form a mold cavity 3. The mold cavity 3 has an opening on one side to form an opening side 31 corresponding to the opening of the electronic connector housing 8. A pouring channel 4 is formed between the first mold base 1 and the second mold base 2 to connect the mold cavity 3 and the outside.
[0032] The demolding mechanism 5 includes a drive seat 51 with a first demolding part 52 at one end, two drive members 53 with a second demolding part 54 at one end, and a demolding drive mechanism for driving the drive seat 51 and drive members 53 to move. The two second demolding parts 54 are detachably disposed on both sides of the first demolding part 52 and together form a mold core 6 located in the mold cavity 3. The drive seat 51 is blocked on the opening side 31. A molding cavity 7 adapted to the electronic connector housing 8 is formed between the outer wall of the mold core 6 and the inner wall of the mold cavity 3. The demolding drive mechanism is used to drive the first demolding part 52 and the two second demolding parts 54 to move outward sequentially after the mold is opened for demolding.
[0033] The above structure, through the addition of the demolding mechanism 5, not only allows the mold core 6 to be formed through the first demolding part 52 and the second demolding part 54 during mold closing, and the outer wall of the mold core 6 to form a molding cavity 7 for casting the electronic connector housing 8 between the inner wall of the mold cavity 3, but also allows the first demolding part 52 and the two second demolding parts 54 to be driven outward sequentially for demolding after mold opening by the demolding drive mechanism. Thus, when the inner diameter of the inner end of the electronic connector formed in the molding cavity 7 is larger than the opening side 31, the drive seat 51 can be driven to move until the first demolding part 52 disengages from the two second demolding parts 54, freeing up demolding space, and then the two second demolding parts 54 can be driven to move towards the opposite side and then be driven outward for demolding. This allows the casting mold to be successfully demolded for different types of electronic connector housings 8 without damaging the electronic connector housing 8, thus improving the adaptability of the casting mold.
[0034] To reduce driving costs, the demolding drive mechanism includes a telescopic end 571 connected to the drive seat 51 and a movable seat 55 movably disposed along the telescopic direction of the telescopic end 571. The other ends of the two drive members 53 are movably connected to the movable seat 55. The two drive members 53 are inclined and the distance between them gradually increases from one end to the other. The drive seat 51 is slidably sleeved on the two drive members 53, and the first demolding part 52 is located between the two drive members 53. Thus, during the demolding process after mold opening, the telescopic end 571 of the demolding drive mechanism drives the drive seat 51 to move towards the two drive members 53. When one end moves, the first demolding part 52 disengages from the two second demolding parts 54, and the two driving members 53 are pressed and driven to move towards each other until they abut each other. Then, the driving seat 51 pulls the two driving members 53 together to move away from the mold cavity 3, thus completing the demolding action. The sequential movement, linkage movement, and opposite movement of the driving seat 51 and the two driving members 53 are realized through a single driving mechanism, which greatly reduces the driving cost, thereby reducing the overall production cost of the casting mold, reducing the space ratio of the casting mold, and improving its installation adaptability.
[0035] To improve the stability of the demolding drive mechanism, the first mold base 1 and the second mold base 2 are distributed vertically. The demolding drive mechanism also includes a fixed base 56 installed on the top of the second mold base 2, and a hydraulic cylinder 57 disposed on the fixed base 56 and including the telescopic end 571. The movable seat 55 is laterally slidably disposed in the fixed base 56. The telescopic end 571 is laterally slidably disposed through the movable seat 55 and connected to the drive seat 51. The drive seat 51 is laterally slidably disposed in the fixed base 56 and located between the opening side 31 and the movable seat 55. The movable seat 55 is recessed on the side near the drive seat 51 and has a vertically extending sliding groove 551. The other ends of the two drive members 53 are vertically limited and slidably disposed in the sliding groove 551. Specifically, the pressing drive device can be configured as a hydraulic cylinder 57 that drives the first mold base 1 to press downwards onto the second mold base 2. The above structure improves the stability of the lateral movement of the drive seat 51 and the movable seat 55 by setting the fixed seat 56, and improves the stability of the two drive components 53 moving towards or away from each other by setting the sliding groove 551, thereby improving the overall driving stability of the demolding drive mechanism.
[0036] Specifically, the two second demolding parts 54 protrude outward from the opposite side away from the opening side 31 to form an expansion part 541. The upper and lower sides of the drive seat 51 are respectively provided with elongated sliding holes 511. The sidewalls of the two sliding holes 511 extend to form a blocking part 512 for blocking the opening side 31. The two drive members 53 are plate-shaped with their wide surfaces facing each other and respectively adapted to be inclined through the two sliding holes 511. The included angle between the opposite sides of the two second demolding parts 54, the included angle between the upper and lower sides of the first demolding part 52, and the included angle between the two drive members 53 are the same.
[0037] To improve the stability of the sliding fit between the two driving components 53 and the driving seat 51, a plurality of limiting ribs 58 are raised on the opposite sides of the two driving components 53 and the opposite sides of the two second demolding parts 54. The upper and lower sides of the first demolding part 52 and the sliding hole 511 are recessed together with limiting grooves 59 that are adapted to the plurality of limiting ribs 58. The groove width of the limiting grooves 59 on the upper and lower sides gradually decreases in opposite directions. The plurality of limiting ribs 58 are respectively slidably embedded in the plurality of limiting grooves 59 along the axial direction. Specifically, the limiting grooves 59 are set as dovetail grooves. In other embodiments, they can also be set as other limiting shapes. The above structure sets the included angle between the two opposite sides of the two second demolding parts 54, the included angle between the upper and lower sides of the first demolding part 52, and the included angle between the two driving members 53 to be the same. Through the cooperation between a number of limiting ribs 58 and a number of limiting grooves 59, the driving seat 51 and the first demolding part 52 are connected to the two driving members 53 and the two second demolding parts 54 in a limited sliding connection along the front and rear axis. Furthermore, the limiting ribs 58 are embedded in the limiting grooves 59 to limit the upper and lower and left and right sides of the driving seat 51 and the first demolding part 52 and the two driving members 53 and the two second demolding parts 54, thereby preventing displacement or slippage and improving the stability of the sliding cooperation between the two driving members 53 and the driving seat 51.
[0038] To improve casting stability, the fixed base 56 is recessed with a plurality of first positioning grooves 561 located outside the opening side 31 and second positioning grooves 562 located on both sides. The bottom of the first mold base 1 is provided with a plurality of first positioning posts 12 and a plurality of second positioning posts 13 corresponding to the plurality of first positioning grooves 561 and second positioning grooves 562. The plurality of first positioning posts 12 are used to be inserted into the plurality of first positioning grooves 561 and limited to abutting against the outside of the drive seat 51 when the mold is closed and the drive seat 51 is blocked at the opening side 31. Thus, through the cooperation between the first positioning posts 12 and the first positioning grooves 561, the drive seat 51 is stably blocked at the opening side 31 of the mold cavity 3 after the mold is closed, and the fixed base 56 is pressed and fixed through the cooperation between the second positioning posts 13 and the second positioning grooves 562, thereby improving the stability of the fixed base 56 after the mold is closed.
[0039] To further facilitate demolding of the electronic connector housing 8 after molding, the second mold base 2 and the second mold core 21 are vertically provided with a plurality of first demolding channels 22 and a plurality of second demolding channels 23 corresponding to the pouring channel 4 and the mold cavity 3, respectively. A first demolding rod 24 and a second demolding rod 25, which are driven to extend upward by the upper push driving mechanism, are respectively inserted into the plurality of first demolding channels 22 and the plurality of second demolding channels 23.
[0040] In order to guide the mold closing between the first mold base 1 and the second mold base 2, the first mold base 1 and the second mold base 2 are respectively provided with a number of vertically corresponding guide pillars 14 and guide holes 26.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
