Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a mold structure for embedding a copper busbar into a DC terminal block. Background Technology

[0002] The DC terminal block embedding copper busbar insert mold structure is used to realize one-time embedding of copper busbar and one-piece molding of insulating plastic shell. The copper busbar can form an inseparable whole with the plastic shell without secondary assembly, eliminating multiple stations such as subsequent insertion, riveting, and screw tightening. The cycle time of a single piece is shortened by more than 30%. Moreover, the copper busbar is completely covered by the plastic shell, eliminating the failure risk caused by loosening, corrosion or electric arc of traditional terminal blocks, and greatly improving electrical performance and mechanical life.

[0003] Although existing mold structures utilize sliding mechanisms to avoid interference with demolding, some sliding parts require additional hydraulic cylinders for driving, necessitating multiple components such as traditional inclined guide pillars, wedge blocks, and pressure bars. This increases the thickness of the mold and raises manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to provide a mold structure for embedding copper busbars into DC terminals, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A DC terminal block embedded copper busbar insert mold structure includes an upper fixed plate connected to an injection molding machine. A female template is fixedly connected to the lower surface of the upper fixed plate. Guide pillars are fixedly connected to the lower surface of the upper fixed plate near the four corners. A male template is slidably connected to the outer surface of the guide pillars. An ejector mechanism mounting plate is fixedly connected to the lower surface of the male template. A mold foot is fixedly connected to the lower surface of the ejector mechanism mounting plate. A lower fixed plate is fixedly connected to the lower surface of the mold foot.

[0007] The upper surface of the male template is movably connected to a sliding mechanism, which includes a limiting column, a connecting block, and a buffer pad. The limiting column is fixedly connected to the upper surface of the male template, and a slider is slidably connected to the lower surface of the limiting column. The connecting block is fixedly connected to the side surface of the slider, and the buffer pad is fixedly connected to the upper surface of the connecting block. The lower surface of the female template is fixedly connected to a guiding mechanism, which includes an mounting block and a guide post. The mounting block is fixedly connected to the lower surface of the female template, and the guide post is embedded in the lower surface of the mounting block.

[0008] Furthermore, the lower surface of the female template is embedded with a female mold core, and the upper surface of the male template is embedded with a male mold core.

[0009] Furthermore, the upper surface of the slider is provided with a guide hole, the guide post and the guide hole are slidably connected, the outer surface of the buffer pad is embedded with a bolt, and the buffer pad, the slider and the connecting block are connected by bolts.

[0010] Furthermore, a first side mold is slidably connected to the upper surface of the male template near one side, and a second side mold is slidably connected to the upper surface of the male template near the other side.

[0011] Furthermore, the outer surface of the guide post is provided with a slot, and the side surface of the mounting block is embedded with a socket, which passes through the slot.

[0012] Furthermore, the side surface of the socket is threaded with a first bolt, and the lower surface of the mounting block is threaded with a second bolt.

[0013] Furthermore, the mounting block is fixedly connected to the mother template by a second bolt, and the planar positions of the second bolt and the first bolt are in contact.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During the process of the sliding block moving downward with the help of the template and the limiting column, the guide column and the guide hole move relative to each other, applying an outward component force to the sliding block. This component force drives the sliding block and the connecting block to move outward, eliminating the need for hydraulic cylinder drive and avoiding interference between the first side mold and the second side mold for the subsequent ejection of the plastic part. The guide column also serves as a positioning pin, drive pin and anti-rotation pin, eliminating the need for traditional inclined guide columns, wedge blocks, pressure strips and other parts, reducing the overall thickness of the mold.

[0016] 2. One end of the socket is inserted into the slot. The first bolt is used to install the socket and the mounting block together to prevent the guide post from rotating. The first bolt and the second bolt abut against each other to prevent the second bolt from rotating. During the use of the mold, the second bolt is prevented from being loosened by vibration.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 In this embodiment of the utility model, the DC terminal block embedded copper busbar insert mold structure includes an upper fixing plate 1 connected to an injection molding machine. A female template 2 is fixedly connected to the lower surface of the upper fixing plate 1. Guide pillars 101 are fixedly connected to the lower surface of the upper fixing plate 1 near the four corners. A male template 3 is slidably connected to the outer surface of the guide pillars 101. An ejector mechanism mounting plate 402 is fixedly connected to the lower surface of the male template 3. A mold foot 401 is fixedly connected to the lower surface of the ejector mechanism mounting plate 402. A lower fixing plate 4 is fixedly connected to the lower surface of the mold foot 401.

[0025] A sliding mechanism 5 is movably connected to the upper surface of the male template 3. The sliding mechanism 5 includes a limiting column 506, a connecting block 503, and a buffer pad 504. The limiting column 506 is fixedly connected to the upper surface of the male template 3. A slider 501 is slidably connected to the lower surface of the limiting column 506. The connecting block 503 is fixedly connected to the side surface of the slider 501. The buffer pad 504 is fixedly connected to the upper surface of the connecting block 503. A guide mechanism 8 is fixedly connected to the lower surface of the female template 2. The guide mechanism 8 includes an mounting block 801 and a guide post 802. The mounting block 801 is fixedly connected to the lower surface of the female template 2. The guide post 802 is embedded in the lower surface of the mounting block 801.

[0026] Specifically, the upper fixed plate 1 is locked to the fixed template of the injection molding machine via a positioning ring, and the lower fixed plate 4 is locked to the moving template of the machine. The female template 2 is fixed to the lower surface of the upper fixed plate 1, and the male template 3 slides along the guide post 101. The copper busbar body 701 is first placed on the male mold core 301 on the male template 3. After the mold opens, the slider 501 moves laterally, and then the ejector mechanism mounting plate 402 drives the ejector pin to eject the finished product. The mold foot 401 provides movement space for the ejector mechanism. The entire mold completes one injection cycle. The injection-molded product, the connector body 7, is as follows: Figure 3 As shown, when the slider 501 moves along the limiting column 506, it simultaneously drives the connecting block 503 to move.

[0027] Example 1

[0028] like Figure 1-5 As shown, a female mold core 201 is embedded and connected to the lower surface of the female mold 2, and a male mold core 301 is embedded and connected to the upper surface of the male mold 3.

[0029] In this embodiment, the female mold core 201 and the male mold core 301 are used to form the cavity of the plastic part. For the slots on the side surface, the first side mold 6 and the second side mold 601 are used for shaping.

[0030] like Figure 1-5 As shown, a first side mold 6 is slidably connected to the upper surface of the male template 3 near one side, and a second side mold 601 is slidably connected to the upper surface of the male template 3 near the other side. There are two connecting blocks 503, one of which is fixedly connected to the first side mold 6, and the other is fixedly connected to the second side mold 601.

[0031] In this embodiment, based on the shaping by the first side mold 6 and the second side mold 601, the first side mold 6 and the second side mold 601 can be moved outward to avoid interference with the ejection of the plastic part later.

[0032] Example 2

[0033] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to apply the force required for sliding out of slider 501 in Embodiment 1.

[0034] like Figure 1-4 As shown, a guide hole 502 is provided on the upper surface of the slider 501, the guide post 802 is slidably connected to the guide hole 502, and a bolt is embedded in the outer surface of the buffer pad 504. The buffer pad 504, the slider 501 and the connecting block 503 are connected by bolts.

[0035] In this embodiment, during the process of the male template 3 moving the slider 501 downward with the help of the limiting column 506, the guide column 802 and the guide hole 502 move relative to each other, applying an outward component force to the slider 501. This component force drives the slider 501 and the connecting block 503 to move outward. The buffer pad 504 is used to avoid the rigid connection between the mounting block 801 and the connecting block 503, making the sliding mechanism simpler and further reducing the thickness of the mold.

[0036] like Figure 1-5 As shown, the outer surface of the guide post 802 is provided with a slot 803, and the side surface of the mounting block 801 is embedded with a socket 804. The socket 804 passes through the slot 803, and the side surface of the socket 804 is threaded with a first bolt 805. The lower surface of the mounting block 801 is threaded with a second bolt 806. The mounting block 801 is fixedly connected to the mother template 2 by the second bolt 806. The plane positions of the second bolt 806 and the first bolt 805 are in contact.

[0037] In this embodiment, after the guide post 802 is installed on the mounting block 801, one end of the socket 804 is inserted into the slot 803. The first bolt 805 is used to install the socket 804 and the mounting block 801 together, which can prevent the guide post 802 from rotating. The first bolt 805 and the second bolt 806 abut against each other to prevent the second bolt 806 from rotating. During the use of the mold, the second bolt 806 is prevented from being loosened by vibration. Therefore, the guide post 802 can only be pulled out and disassembled and replaced after the first bolt 805 is removed and the socket 804 is taken out.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
