Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically a leak-proof injection mold for automotive sunroofs. Background Technology

[0002] A car sunroof is installed on the roof of a vehicle, which can effectively circulate air inside the car and increase the intake of fresh air. At the same time, car windows can also expand the field of vision and meet the needs of mobile photography and videography. Car sunroofs can be roughly divided into: sliding type, concealed type, concealed and tilting type, panoramic type and curtain type, etc. They are mainly installed on commercial SUVs, sedans and other models. In order to ensure the waterproof and airtightness of the sunroof, the glass and bracket are usually guaranteed to be airtight during production and installation. Water is guided out by a drain pipe installed inside the bracket.

[0003] However, because some car sunroofs have a two-section drainage pipe design, the connector at the connection point between the two ends is plugged in and is prone to coming loose, becoming a leak point, thus making leaks more likely. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a leak-proof automotive sunroof injection mold, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a leak-proof automotive sunroof injection mold, comprising an injection mold body, the injection mold body including: an upper mold and a lower mold, the upper surface of the lower mold having a die, one end of the inner side of the die having a pad groove, the other end of the inner side of the die having a slotted protrusion, both the pad groove and the slotted protrusion having ejector rods inside, the die having an inner rod inside the die near the pad groove, the side end of the inner rod having an opening rod installed, the die having a threaded inner rod inside the die near the slotted protrusion, and a connector tube being provided on the outer side between the threaded inner rod and the inner rod.

[0006] As a further embodiment of this utility model: a pad is provided on the outside of the connector tube inside the pad slot, a hanging hole is provided inside the pad on the outside of the perforated rod, a binding groove is provided on the outside of the connector tube corresponding to the slot protrusion, and an installation thread is provided at the end of the connector tube on the outside of the threaded inner rod.

[0007] As a further embodiment of this utility model: a drive motor is connected to the outer end of the threaded inner rod, a hydraulic cylinder is connected to the outer end of the inner insertion rod, a limiting groove is formed inside the mold on the outer side of the inner insertion rod, and a base is installed at the lower end of the lower pressing mold.

[0008] As a further improvement of this utility model: the upper surface of the upper mold is provided with an injection hole corresponding to the position of the mold, and the connector tube is a PVC material component.

[0009] As a further embodiment of this utility model: the pad slot and the slotted protrusion are integrally formed with the mold, and the perforated insert rod is fixedly connected to the inner insert rod.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] like Figure 1-5 As shown, this embodiment provides a leak-proof automotive sunroof injection mold, including an injection mold body 1. The injection mold body 1 includes an upper mold 2 and a lower mold 3. A mold 301 is formed on the upper surface of the lower mold 3. An upper mold of the same size as the mold 301 is formed on the lower surface of the upper mold 2. An injection hole is formed on the upper surface of the upper mold 2 corresponding to the position of the mold 301. A pad groove 306 is formed on one end of the inner side of the mold 301, and a slotted protrusion 307 is formed on the other end of the inner side of the mold 301. The pad groove 306 and the slotted protrusion 307 are integrally formed with the mold 301. An ejector rod 308 is formed inside the pad groove 306 and the slotted protrusion 307. An inner insertion rod 303 is provided inside the mold 301 on the side near the pad groove 306. An opening insertion rod 30 is installed on the side end of the inner insertion rod 303. 5. The perforated insert rod 305 is fixedly connected to the inner insert rod 303. The mold 301 is provided with a threaded inner rod 304 inside the side near the slotted protrusion 307. The outer diameter of the inner insert rod 303 is the same as that of the threaded inner rod 304. A connector tube 7 is provided on the outer side between the threaded inner rod 304 and the inner insert rod 303. The outer end of the threaded inner rod 304 is connected to a drive motor 6. The drive motor 6 can drive the threaded inner rod 304 to rotate and move as a whole, which can prevent damage to the internal threads during material removal. The outer end of the inner insert rod 303 is connected to a hydraulic cylinder 5. The mold 301 is provided with a limiting groove 302 on the outer side of the inner insert rod 303. The inner insert rod 303 is slidably connected to the limiting groove 302. A movable connecting rod is connected between the hydraulic cylinder 5 and the inner insert rod 303. A base 4 is installed at the lower end of the lower die 3.

[0018] like Figure 2-3As shown, in this embodiment, a pad 701 is provided inside the pad slot 306 on the outside of the connector tube 7. The connector tube 7 is a PVC material component. A hanging hole 702 is provided inside the pad 701 on the outside of the perforated insertion rod 305. A binding reserved groove 703 is provided on the outside of the connector tube 7 corresponding to the slotted protrusion 307. An installation thread 704 is provided at the end of the connector tube 7 on the outside of the threaded inner rod 304. The installation thread 704 inside the connector tube 7 can be used to engage with the connector of the drain pipe. After the other end of the connector tube 7 is glued and fixed to the drain pipe at the other end, the binding tape is clamped and fixed through the binding reserved groove 703 on the outside of the connector tube 7. Then, the excess binding tape is passed through the hanging hole 702 inside the pad 701 and wrapped and fixed, so that the connector tube 7 and the drain pipe can be detached.

[0019] The working principle of this utility model is as follows: During use, the hydraulic cylinder 5 controls the inner insert rod 303 to move within the limiting groove 302 inside the mold 301. Simultaneously, the hydraulic cylinder 5 controls the threaded inner rod 304 to move, thus bringing the end of the inner insert rod 303 and the threaded inner rod 304 into contact and filling the interior of the mold 301. The upper mold 2 is then moved downwards to cover the upper surface of the lower mold 3. Molten material is then injected into the mold 301 through the injection port. Once the material is formed and fixed within the mold 301 between the inner insert rod 303 and the threaded inner rod 304, the hydraulic cylinder 5 drives the inner insert rod 303 to move outwards, from the connector tube 7... After being pulled out from the inside, the threaded inner rod 304 is rotated by the hydraulic cylinder 5 to disengage from the inside of the connector tube 7. Then, the connector tube 7 is pushed out from the inside of the mold 301 by the ejector rod 308. After applying glue to the inner wall of the end of the connector tube 7 near the pad 701, it is glued to the drain pipe of the sunroof. After engaging the installation thread 704 of the connector tube 7 with another drain pipe, the binding tape is clamped and fixed from the binding groove 703 on the outside of the connector tube 7. Then, the excess binding tape is passed through the hanging hole 702 inside the pad 701 and wrapped and fixed. When the embossed joint position ages and falls off, the binding tape will hang inside the hanging hole 702 to prevent the pipe from falling off.
