Description

Technical Field

[0001] This utility model relates to the technical field of a mold release structure, specifically a high-efficiency mold release structure for a notebook connector mold. Background Technology

[0002] As connectors for data transmission and functional expansion in laptops, the traditional USB Type-A interface continues to serve peripheral connections thanks to its wide compatibility. USB Type-C, with its reversible plug, up to 40Gbps bandwidth (such as the USB4 protocol), and PD fast charging capabilities, has become a standard feature in mainstream models, supporting simultaneous data transmission, video output, and power delivery of over 65W. It can even achieve multi-screen 4K display and gigabit network access via docking stations. While HDMI and DisplayPort interfaces face pressure from Type-C integration, they remain reliable choices for connecting external monitors and projectors. DisplayPort 2.0, in particular, supports 8K@60Hz high-resolution output. The Thunderbolt 4 interface further increases bandwidth to 40Gbps and supports PCIe... 4.0 direct connection and dynamic bandwidth allocation, combined with daisy-chain topology, can connect multiple devices to meet the high bandwidth requirements of professional creation, VR devices, etc. In terms of audio interfaces, although the 3.5mm headphone jack has been removed from some thin and light laptops due to the trend of integration, high-fidelity audio transmission can still be maintained through the Type-C audio adapter, while the built-in digital microphone interface optimizes the voice recognition and conference call experience. As a key interface for storage expansion, the SD / TF card slot will be replaced in some wired connection scenarios with the maturity of wireless technologies such as Wi-Fi 6 and UWB, but the advantages of wired connection in high-speed transmission, low latency, and stable power supply are still irreplaceable.

[0003] In the connector pin soldering process, traditional manual soldering of connectors has low soldering precision, low efficiency, and poor product performance consistency, and cannot control the generation of problems such as soldering cracks and cold solder joints. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a highly efficient demolding structure for a notebook connector mold. The second hydraulic cylinder in the positioning assembly drives the positioning guide pin to extend from the positioning plate, which, together with the locking strip on the positioning plate and the lower receiving cavity of the mold base, forms a limit on the connector, thereby improving the welding position accuracy. Through the linkage between the drive cylinder and the first hydraulic cylinder in the demolding mechanism, and the sliding connection between the guide groove and the mold cover, the problems of low efficiency and mold movement deviation in traditional manual welding are solved. When the drive cylinder retracts, it simultaneously lowers the mold cover and presses in the first hydraulic cylinder. The piston rod of the first hydraulic cylinder synchronously drives the positioning guide pin at the output end of the second hydraulic cylinder to extend. At the same time, the guide groove guides the mold cover to move along a fixed path. In conjunction with the auxiliary limiting connector of the rib on the side wall of the receiving cavity, it solves the problems of poor weld point accuracy and false weld caused by the inaccuracy of traditional manual welding, thereby improving welding efficiency and weld point consistency. Through the rebound action of the first hydraulic cylinder and the auxiliary spring, the auxiliary spring provides a reset elastic force to buffer the impact force of the mold, solving the problem of product damage caused by mechanical stress concentration during assembly. This protects the connector from mechanical stress damage and improves product yield and quality stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency demolding structure for a notebook connector mold includes a mold base, a demolding mechanism on one side of the mold base, and a mold cover on the mold base. The mold cover is fixedly connected to the demolding mechanism, which drives the mold cover to detach from the mold base. The demolding mechanism includes a demolding box fixedly connected to the mold base, a drive cylinder on each side of the demolding box, a connector at the output end of the two drive cylinders, a first hydraulic cylinder between the two drive cylinders, and a connection between the mold base and the mold cover. The positioning assembly includes a drive cylinder that provides driving force to move the mold cover via a connector. One side of the connector is fixedly connected to one end of the piston rod of the first hydraulic cylinder. The positioning assembly includes a positioning plate fixedly connected to the mold base, two second hydraulic cylinders disposed within the positioning plate, and a positioning guide pin disposed at the output end of the second hydraulic cylinders. The two second hydraulic cylinders are connected to the first hydraulic cylinder via hydraulic oil pipes. The second hydraulic cylinders are used to push the positioning guide pin out of the positioning plate. The positioning plate is used to position the connector via the positioning guide pin.

[0007] An auxiliary spring is installed on the piston rod of the first hydraulic cylinder. One end of the auxiliary spring is fixedly connected to the demolding box, and the other end of the auxiliary spring is provided with a contact plate. The auxiliary spring is used to assist the resetting of the connecting parts.

[0008] The demolding box has two guide grooves on one side, which are used to slide and connect the mold cover.

[0009] The mold cover includes a cover body and a mounting block located on one side of the cover body. The mounting block is fixedly connected to one end of the connector.

[0010] The upper cover body has an upper receiving cavity, and the side wall of the receiving cavity has several ribs. The upper receiving cavity is used to receive the connector, and the ribs are used to assist in limiting the connector.

[0011] The mold base is provided with a lower receiving cavity that matches the length and width of the receiving cavity on the upper cover body. The lower receiving cavity is used to accommodate the connector in conjunction with the upper receiving cavity.

[0012] The connector includes a square connecting block fixedly connected to the output end of each of the two drive cylinders, a hydraulic cylinder connecting block disposed between the two square connecting blocks, and an upper mold connecting block fixedly connected to the upper cover of the mold.

[0013] The positioning plate is provided with an assembly cavity for assembling the second hydraulic cylinder.

[0014] The positioning plate is provided with a locking strip, which is used to assist in limiting the connector.

[0015] The mold base is provided with several mounting holes, which are used to mate with bolts to install the mold base onto the equipment that produces connectors.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The positioning guide pin is driven to extend out of the positioning plate by the second hydraulic cylinder in the positioning assembly. It works with the locking strip on the positioning plate to form the limit of the connector with the lower receiving cavity of the mold base, thereby improving the welding position accuracy.

[0018] 2. Through the linkage between the drive cylinder and the first hydraulic cylinder in the demolding mechanism and the sliding connection between the guide slide and the mold cover, when the drive cylinder retracts, it simultaneously drives the mold cover to descend and press into the piston rod of the first hydraulic cylinder, and simultaneously drives the positioning guide pin at the output end of the second hydraulic cylinder to extend. At the same time, the guide slide guides the mold cover to move along a fixed path. With the auxiliary limiting connector of the rib on the side wall of the receiving cavity, the welding efficiency and weld consistency are improved.

[0019] 3. Through the rebound action of the first hydraulic cylinder and the auxiliary spring, the auxiliary spring provides a reset spring force to buffer the impact force of the mold, thereby protecting the connector from mechanical stress damage and improving product yield and quality stability.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figure 1-9As shown, this utility model relates to an efficient demolding structure for a mold used in a notebook connector. It includes a mold base 1 with several mounting holes 10 for mounting the mold base 1 onto a connector manufacturing device using bolts. A demolding mechanism 2 is located on one side of the mold base 1. A mold cover 3 is mounted on the mold base 1 and is fixedly connected to the demolding mechanism 2. The demolding mechanism 2 drives the mold cover 3 to detach from the mold base 1. The demolding mechanism 2 includes a demolding box 20 fixedly connected to the mold base 1, a drive cylinder 21 on each side of the demolding box 20, a connector 22 at the output end of the two drive cylinders 21, and a first hydraulic cylinder 23 between the two drive cylinders 21. The positioning assembly 24 is located between the mold base 1 and the mold cover 3. The drive cylinder 21 is used to drive the mold cover 3 to move via the connector 22. One side of the connector 22 is fixedly connected to one end of the piston rod 230 of the first hydraulic cylinder 23. The piston rod 230 includes a first piston rod and a second piston rod slidably connected via an adjustment bracket. The top end of the second piston rod is connected to the connector. The first piston rod passes through the cylinder of the first hydraulic cylinder 23. The adjustment bracket is used to adjust the effective hydraulic stroke of the first hydraulic cylinder 23 to ensure the hydraulic power of the second hydraulic cylinder 241. The adjustment bracket has several sliding sleeve holes. The end plate at one end of the second piston rod is provided with a sliding optical shaft passing through the sliding sleeve hole. When the drive... When cylinder 21 drives connector 22 to move downward, connector 22 drives the second piston rod to move downward. At this time, the sliding optical shaft slides in the sliding sleeve hole. After moving downward to the adjustment stroke (the upper limit plate of the adjustment frame abuts against the first piston rod), the adjustment frame drives the first piston rod to compress the hydraulic oil in the cylinder of the first hydraulic cylinder 23. An auxiliary spring 25 is installed on the piston rod 230 of the first hydraulic cylinder 23. One end of the auxiliary spring 25 is fixedly connected to the demolding box 20, and the other end of the auxiliary spring 25 is provided with a contact plate 250. The contact plate 250 is provided with a sliding hole for assembling the piston rod 230. The contact plate 250 is used to abut against connector 22 when the mold cover 3 moves downward. The auxiliary spring 25 is used to assist connector 22 to return to its original position and prevent the mold from moving downward. When the upper cover 3 moves down and closes with the mold base 1, the mechanical pressure is too great and damages the connector. The demolding box 20 has two guide slides 200 on one side. The two guide slides 200 are arranged in parallel and opposite to each other. The guide slides 200 are used to slide and connect the upper cover 3 of the mold. The demolding box 20 has a first mounting cavity 201 of the drive cylinder 21 on both sides and a second mounting cavity 202 of the first hydraulic cylinder 23 in the middle. The connecting piece 22 includes a square connecting block 220 fixedly connected to the output end of the two drive cylinders 21, a cylinder connecting block 221 disposed between the two square connecting blocks 220, and an upper mold connecting block 222 fixedly connected to the upper cover 3 of the mold. The square connecting block 220, the cylinder connecting block 221 and the upper mold connecting block 222 are all provided with several threaded assembly holes.The positioning assembly 24 includes a positioning plate 240 fixedly connected to the mold base 1, two second hydraulic cylinders 241 disposed within the positioning plate 240, and a positioning guide pin 242 disposed at the output end of the second hydraulic cylinders 241. The two second hydraulic cylinders 241 are connected to a first hydraulic cylinder 23 via hydraulic oil pipes 26. The second hydraulic cylinders 241 are used to push the positioning guide pin 242 out of the positioning plate 240. The positioning plate 240 is used to position the connector via the positioning guide pin 242. The positioning plate 240 has an assembly cavity 2400 for assembling the second hydraulic cylinders 241. The positioning plate 240 also has a locking strip 2401 for assisting in limiting the connector.

[0033] like Figure 1-6 As shown, the mold cover 3 includes a cover body 30 and a mounting block 31 located on one side of the cover body 30. The mounting block 31 is fixedly connected to one end of the connector 22. The cover body 30 has an upper receiving cavity 300. The upper receiving cavity 300 has several ribs 301 on its side wall. The upper receiving cavity 300 is used to receive the connector, and the ribs 301 are used to assist in limiting the connector. The mold base 1 has a lower receiving cavity 11 that matches the length and width of the upper receiving cavity 300 of the cover body 300. The lower receiving cavity 11 is used to cooperate with the upper receiving cavity 300 to receive the connector.

[0034] like Figure 1-9 As shown, during assembly, firstly, the second hydraulic cylinder 241 is installed in the assembly cavity 2400 of the positioning plate 240. Then, the positioning plate 240 is installed on the bottom surface of the lower receiving cavity 11 of the mold base 1 using bolts. Next, the first hydraulic cylinder 23 is installed in the second mounting cavity 202 of the demolding box 20. At the same time, the drive cylinders 21 are respectively installed in the first mounting cavities 201 on both sides of the demolding box 20. The auxiliary spring 25 is sleeved on the piston rod 230 of the first hydraulic cylinder 23, and its lower part is fixed to the demolding box 20 by bolts. The connecting piece 22 is connected to the piston rod 230 and the drive cylinder 21 by bolts. Rod 210 is fixedly connected, and hydraulic oil pipe 26 is laid along the pipeline in the demolding box 20 and the positioning plate 240. The first hydraulic cylinder 23 and the second hydraulic cylinder 241 are connected through a three-way valve. The demolding box 20 and the mold base 1 are fixedly connected by bolts. Then, the mounting block 31 of the mold cover 3 is brought into contact with the guide slide groove 200 on both sides of the demolding box 20. It is fixedly connected to the upper mold connecting block 222 by bolts. The drive cylinder 21 is connected to the external air source equipment. Initially, the drive rod 210 of the drive cylinder 21 is in the extended state, and the mold cover 3 and the mold base 1 are in the open state.

[0035] like Figure 1-9As shown, during use, when the robotic arm transfers the connector onto the mold base 1, the drive cylinder 21 activates the retraction drive rod 210, causing the connector 22 to move downwards. The connector 22 then causes the mold cover 3 to descend synchronously, covering the connector within the upper receiving cavity 300 of the mold cover 3. Simultaneously, the connector 22 presses down on the piston rod 230 of the first hydraulic cylinder 23. The piston rod 230 forces the hydraulic oil in the cylinder into the cylinder of the second hydraulic cylinder 241 through the hydraulic oil pipe 26. The second hydraulic cylinder 241 drives the positioning guide pin 242 at the output end to extend out of the positioning plate 240. As the drive cylinder 21 continues to move the mold cover 3 downwards, the connector moves along the positioning guide pin 242 to contact the mold base. When the lower receiving cavity 11 of seat 1 is closed, and the upper cover 3 of the mold is closed with the mold base 1, the drive cylinder 21 stops working, the welding equipment works, and after the welding of the connector pins is completed, the drive cylinder 21 starts again, and the reverse drive rod 210 extends out of the cylinder, lifting the upper cover 3 and separating it from the mold base 1. At the same time, the piston rod 230 of the first hydraulic cylinder 23 returns to its original position, and the hydraulic oil in the second hydraulic cylinder 241 is drawn back into the first hydraulic cylinder 23 through the hydraulic oil pipe 26, so that the positioning guide pin 242 retracts into the positioning plate 240, completing the efficient separation of the upper cover 3 from the mold base 1. The robot then transfers the connector and performs the next action.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
