Description

Technical Field

[0001] This utility model relates to the technical field of mold ejection mechanisms, and in particular to a linkage-type faucet ejection mechanism. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping.

[0003] When the faucet body is injection molded, the ejection method of the transmission mold is supported and moved from below the mold. However, since the faucet body has a certain tilt angle and the lower end of the faucet needs to be machined with installation threads, placing both the faucet part and the ejection part at the bottom can easily cause the stroke to overlap, affecting the accuracy of product molding. In addition, the existing injection molding stations are few, which limits the number of products that can be molded in a single injection.

[0004] Therefore, we provide a linkage-type faucet ejection mechanism. Utility Model Content

[0012] Preferably, the two ejector plates are located between the two forming support blocks, and the ejector plates move along the arcuate edge of the adjacent forming support blocks.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Example 1: A linkage-type faucet ejection mechanism, such as Figures 1-5 As shown, it includes a lower mold body 1, an upper mold body 2, a molded product 9, and a molding auxiliary mechanism and an ejection mechanism disposed above the lower mold body 1.

[0034] The molding auxiliary mechanism includes an injection tube 3 for guiding the injection molding process and a molding fastener 4 for fixing and supporting the molding process.

[0035] The ejection mechanism includes a vertical toothed section and a horizontal ejection section.

[0036] The vertical coiling section includes a coiling cylinder 6, a driven gear 7, and a transmission rod 8. There are several coiling cylinders 6, and each coiling cylinder 6 is connected to a driven gear 7. Several driven gears 7 are simultaneously engaged with the transmission rod 8, and the coiling cylinder 6 is located at the lower end of the forming fixing part 4.

[0037] The horizontal ejection section includes ejection plates 10 and guide rods 11. There are at least two ejection plates 10, and the two ejection plates 10 are stacked together. Guide rods 11 are installed on both sides of the ejection plates 10, and the two guide rods 11 on the same side move in opposite directions.

[0038] When the device is in use, under the injection guide of the injection tube 3, injection is performed simultaneously from above multiple molding fixtures 4, achieving the effect of simultaneous injection molding at multiple stations. When demolding, the upper mold body 2 is removed, and then the existing drive motor on the machine tool is started. The gear on the transmission rod 8 is driven to rotate through the chain, so that the gear on the transmission rod 8 meshes with multiple driven gears 7 on the side at the same time, and the multiple threaded cylinders 6 rotate at the same time, so as to perform threading treatment on the molded product 9. Then the horizontal ejection part is started, so that the two ejection plates 10 move synchronously upwards and diagonally in a symmetrical manner under the guidance of the guide rods 11 on both sides, so that the molded products 9 on both sides are pushed open synchronously upwards and diagonally, so as to eject the molded product 9 at the same time. By setting the ejection movement path to be consistent with the overall specifications of the molded product 9, the accuracy of the ejection mechanism's path and mode during operation is ensured, and the safety of the molded product 9 after molding is improved.

[0039] like Figures 1-5As shown, the molding auxiliary mechanism also includes two symmetrically distributed molding support blocks 5. The surfaces of the two molding support blocks 5 adjacent to each other are provided with guide grooves that can be inserted into the molding fixing parts 4. The molding support blocks 5 and the molding fixing parts 4 are used to limit the molding of the product 9, and several injection ports are provided below the injection tube 3.

[0040] The two ejector plates 10 are located between the two forming support blocks 5, and the ejector plates 10 move along the arc-shaped edge of the adjacent forming support block 5.

[0041] Based on the combined limiting of the molding support block 5 and the molding fixing part 4, the stability of the injection molding specifications of the device is ensured. With the simultaneous support of multiple injection ports on the injection tube 3, multiple molding positions can be injected synchronously, increasing the number of products molded at one time and improving its production efficiency. Under the limitation of the surface specifications of the molding support block 5, the stability and reliability of the angle of the two ejector plates 10 during relative movement are further ensured. By setting the molding fixing part 4 to beryllium copper material, its heat dissipation stability can be ensured while improving its molding support specifications.

[0042] Example 2: A linkage-type faucet ejection mechanism, such as Figures 1-5 As shown, the horizontal ejection part also includes a support block 12 and a movable plate 13. The support block 12 is fixedly installed inside the lower mold body 1, and two symmetrically distributed limiting tracks 14 are provided through the support block 12. The movable plate 13 is slidably connected, and two symmetrically distributed pushing tracks 15 are opened on the inner side of the movable plate 13.

[0043] Two guide rods 11 pass through the limiting rail 14 respectively, and the guide rods 11 are inserted into the push rail 15, and the limiting rail 14 is connected to the push rail 15.

[0044] First, guided by the limiting rails 14 within the support blocks 12 on both sides, the two guide rods 11 on the same side move along opposite inclined paths when pulled. Under the synchronous limiting of the pushing rails 15 by the moving plates 13 on both sides, the direction of movement of the guide rods 11 is limited. Under the moving thrust of the moving plates 13, the pushing rails 15 forcefully push the guide rods 11 to move obliquely upward. Thus, under the combined use of the limiting rails 14 and the pushing rails 15, the two ejector plates 10 move in opposite inclined directions, causing the ejector plates 10 on both sides to open in two directions. This achieves the effect of opening and moving the molded products 9 on both sides to the sides, thereby adapting the ejection method of the device to the structure of the molded product 9 itself, ensuring the stability and safety of the molded product 9 itself during the ejection operation of the device.

[0045] like Figures 1-5 As shown, both sides of the movable plate 13 are simultaneously connected to the pull plate 17. The upper outer side of the pull plate 17 is provided with a limit groove. A forming fixing part 4 is slidably arranged in the limit groove. The forming fixing part 4 is installed in the lower mold body 1.

[0046] A drive cylinder 18 is installed at the rear end of the pull plate 17. The drive cylinder 18 is used for drive support of the horizontal ejection part.

[0047] Driven by the drive cylinder 18, the pull plate 17 moves synchronously. With the pull plate 17 synchronously engaging with the two side moving plates 13, the movement of the two side moving plates 13 is ensured to be stable and accurate. With the positioning rod 16 limiting the movement of the moving plates 13, the position of the moving plates 13 is ensured to be accurate during mold closing movement, thus ensuring the stability and efficiency of the device in ejection movement and mold closing movement.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
