Description

Technical Field

[0001] This utility model relates to the field of mold design, and in particular to a mold for unscrewing the threads of a fuel vehicle tee connector. Background Technology

[0002] The fuel vehicle tee connector is a key component in the fuel delivery system. Its internal structure typically includes internal threads and channels for connecting and distributing fuel lines. Current manufacturing processes for tee connectors largely rely on traditional injection molds. However, traditional mold technology has the following shortcomings regarding the molding and demolding processes of the internal threads:

[0003] Difficulty in demolding internal threads

[0004] Traditional molds typically use forced demolding to form and remove the internal threads of the product, but this method can easily lead to thread damage or product deformation, affecting the quality and precision of the finished product.

[0005] Low demolding efficiency

[0006] Forced demolding or manual intervention in the demolding process is time-consuming, which not only reduces production efficiency but also increases operational complexity, making it difficult to meet the needs of mass production.

[0007] Complex structure, difficult to maintain

[0008] Existing molds typically require additional auxiliary mechanisms and complex drive devices to achieve internal thread forming and demolding. This not only increases the complexity of mold design but also leads to higher maintenance costs in the later stages.

[0009] Therefore, the market urgently needs a tee mold for fuel vehicles that can efficiently achieve internal thread forming, quick demolding, and has a simple structure and convenient operation, in order to solve the above-mentioned problems in the existing technology and meet the growing production needs of the fuel vehicle industry.

[0025] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0026] like Figure 1-3 As shown, this utility model is a mold for unscrewing a three-way connector for fuel vehicles, comprising: a top plate 1, an upper template 2, an upper mold core 3, a lower mold core 4, a lower template 5, a first connecting plate 6, a second connecting plate 7, a support plate 8, an ejector plate 9 disposed between the support plates 8, and a bottom plate 10; the top plate 1 is connected to the upper template 2, and the upper mold core 3 is connected inside the upper template 2; the support plate 8 is connected to the bottom plate 10, the second connecting plate 7 is connected to the support plate 8, the first connecting plate 6 is connected to the second connecting plate 7, the lower template 5 is connected to the first connecting plate 6, and the lower mold core 4 is connected inside the lower template 5; the upper mold core 3 and the lower mold core 4 are used for forming the exterior of the product; an ejector plate 9 is disposed between the two support plates 8, and the ejector plate 9 has ejector pins for ejecting the product after complete demolding. This overall design ensures the stability of the mold structure and the efficient cooperation of the functions of each part, which helps to improve molding accuracy and operational reliability. Specifically:

[0027] A rotating shaft 11 is rotatably connected inside the first connecting plate 6. One end of the rotating shaft 11 passes through the lower template 5 and is placed inside the lower mold core 4. The rotating shaft 11 placed inside the lower mold core 4 has threads on its outside, which are used to form the internal threads of the tee connector product. In order to drive the rotating shaft 11, a motor 12 is installed outside the first connecting plate 6 and is connected to the rotating shaft 11 for transmission. After injection molding is completed, the motor 12 drives the rotating shaft 11 to rotate, thereby unscrewing the product. This realizes an efficient internal thread forming and demolding process, significantly reducing the difficulty of manual operation.

[0028] Multiple guide pillars 16 are provided between the lower template 5 and the first connecting plate 6, and lifting springs 17 are sleeved on the guide pillars 16. The lifting springs 17 are locked between the lower template 5 and the first connecting plate 6. When the product is rotated out, the lower template 5 and the lower mold core 4 are pushed upward by the elastic action of the spring. The restoring force of the spring is used to assist the product demolding, which improves the stability of mold operation and demolding efficiency.

[0029] After injection molding is completed, the upper mold plate 2 drives the upper mold core 3 to open and move. After the mold opens to the designated position, the motor 12 drives the rotating shaft 11 to rotate, thereby unscrewing the product. At the same time as the product is unscrewed, the lower mold plate 5 and the lower mold core 4 are pushed upward by the elastic action of the spring, so as to realize the forming and demolding of the internal thread of the product.

[0030] In this embodiment, a slider 18 is provided in the lower template 5, and a slot that fits the slider 18 is provided in the upper template 2. The end of the slider 18 is connected to an inner mold core 19, which is used to form the internal channel of the product. The slider 18 is slidably connected in the slide rail 21 in the lower template 5. The slide rail 21 has a waist-shaped hole 22 so that the slider 18 can achieve precise sliding positioning during the opening and closing of the mold. The movement of the slider 18 is achieved by the inclined guide post 20 in the upper template 2. When the upper template 2 moves, the inclined guide post 20 interacts with the slider 18, pushing the slider 18 to move along the slide rail 21, thereby driving the inner mold core 19 to complete the forming and demolding of the internal channel of the product. The movement of the slider 18 driven by the inclined guide post 20 ensures the smooth demolding of the inner mold core 19 and improves the forming accuracy.

[0031] In this embodiment, a first gear 13 is mounted on the output shaft of the motor 12, and a second gear 14 is externally connected to the rotating shaft 11. The first gear 13 and the second gear 14 are meshed and transmitted through a third gear 15. The shaft of the third gear 15 is positioned between the first connecting plate 6 and the second connecting plate 7, ensuring good support and transmission efficiency of the gear system during operation. Through the optimized design of the gear transmission structure, stable rotation of the rotating shaft 11 can be achieved, thereby improving the accuracy and efficiency of internal thread forming; the gear transmission enhances the smoothness and reliability of the rotating shaft 11 drive.

[0032] Working principle: During the mold operation, after injection molding is completed, the upper mold plate 2 drives the upper mold core 3 to move upward to open the mold. When the upper mold plate 2 moves to open the mold, the slider 18 also moves synchronously under the action of the inclined guide post 20, ensuring that the inner mold core 19 disengages from the internal channel of the product and completes the demolding process of the inner mold core 19. After the mold is opened, the motor 12 starts to run and drives the rotating shaft 11 to rotate through the gear transmission system. The thread on the rotating shaft 11 meshes with the thread inside the product, and the product is screwed out of the mold by rotation. At the same time, the lifting spring 17 lifts the lower mold plate 5 and the lower mold core 4 through elastic action, further assisting the demolding of the product.
