Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a molding mold for an integrally formed faucet. Background Technology

[0002] A mold, also called a "mold" or "tool," is a precision tool used for mass production of products of specific shapes and sizes. It acts like a "master template," determining the final product's shape, structure, and appearance. A mold typically consists of two (or more) parts forming a cavity. Molten material (such as plastic or metal) or solid material is injected into or placed into this cavity, and then pressure is applied to fill the entire cavity. The material is then allowed to cool and solidify or directly set. Opening the mold yields the finished product, and closing it allows for the next production run. This process can be repeated at high speed, enabling efficient, large-scale production, making it an indispensable core tool for industrialized, large-scale manufacturing.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When the existing faucets are produced, they have multiple channels inside, so it is often necessary to manufacture a sand core that matches the internal structure of the inner core in advance. Then, the hot molten metal is poured into the sand core and cooled and shaped. Then, a sand-knocking process is carried out to remove the sand core and form a cavity. This production method requires the production of a sand core first, which has a high production cost. In addition, sand knocking is required after casting, which involves many steps. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a molding mold for an integrated faucet with fewer molding steps and a simpler process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a molding mold for an integrally formed faucet, comprising an outer mold and an inner mold detachably installed within the outer mold. The outer mold has an integrally formed first injection port, and a connecting frame is installed on one side of the outer mold. A tension frame that slidably engages with the inner mold is provided on the connecting frame. The inner mold comprises an upper mold and a lower mold. The upper mold has an integrally formed second injection port aligned with the first injection port. A pull rod hook structure that engages with the tension frame is provided on one side of the lower surface of the upper mold and one side of the upper surface of the lower mold. The upper surface of the lower mold has an integrally formed faucet-shaped injection groove. The upper surface of the lower mold also has a connecting groove connecting the second injection port and the injection groove. A valve core seat insert with its top aligned with the valve core seat position of the injection groove is detachably provided on the lower surface of the lower mold.

[0006] A further improvement is that the pull rod hook structure consists of two pull rod structures symmetrically distributed on both sides of the upper surface of the lower mold. The pull rod structure includes a swing rod that is movably engaged with one side of the upper surface of the lower mold in the middle section and a pull rod that is movably engaged with one end of the swing rod. The other end of the swing rod is also provided with a hook that can extend into the injection groove.

[0007] A further improvement is that the lower mold can also be detachably equipped with a second water outlet insert, the top of which is aligned with the middle section of the water outlet pipe in the injection molding groove.

[0008] A further improvement is that both the upper and lower molds are provided with fixing holes.

[0009] A further improvement is that the upper mold sidewall is provided with several upper mold mounting holes.

[0010] A further improvement is that the lower mold sidewall is provided with several lower mold mounting holes.

[0011] A further improvement is that a water outlet insert is provided on one side of the lower mold, extending to the end of the water outlet pipe in the injection molding tank.

[0012] A further improvement is that the lower mold has a first slag discharge port on both sides of the faucet body in the injection molding tank, which penetrates the lower mold at the bottom.

[0013] A further improvement is that the lower mold is provided with a second slag discharge port on both sides of the water outlet pipe located in the injection tank, with the bottom penetrating the lower mold.

[0014] A further improvement is that a base is also provided on the lower surface of the outer mold.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, it is only necessary to close the upper mold and the lower mold and fix them with bolts. Its inner cavity will be in the shape of a dragon head. Then, it is installed into the outer mold, so that the first injection port and the second injection port are aligned. The valve core seat insert is installed at its bottom, and a tensioning device is connected to the tensioning frame. The tensioning device pulls the tensioning frame outward, thereby causing the tension rod to swing. Then, the swing rod presses the hook inward, moving it to the position of the valve core seat insert. Then, it is inserted from the first injection port. Hot-melt plastic is injected into the inner mold, filling the injection groove to form a faucet shape. Under the action of the hook and valve core insert, the valve core seat and the curved water channel connected to the valve core seat are formed. After cooling, the hook is pulled back, and the inner and outer molds are removed. The upper and lower molds are opened to obtain the faucet part. Then, holes are drilled in the water outlet pipe of the faucet part and the edges are ground to obtain the finished product. There is no need to use a sand core to form the faucet and its internal water channel. The molding steps are fewer, the production cost is lower, and there is no need for additional processes such as sandblasting after molding, making the molding process faster and simpler.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figure 1-7As shown, the technical solution adopted in this specific embodiment is: a molding mold for an integrally formed faucet, including an outer mold 1 and an inner mold 3 detachably installed in the outer mold 1. The outer mold 1 has a first injection port 2 integrally formed on it. A connecting frame 5 is installed on one side of the outer mold 1. A tension frame 51 that is slidably provided on the connecting frame 5 and is movably engaged with the inner mold 3 is provided. The inner mold 3 includes an upper mold 31 and a lower mold 32. The upper mold 31 has a second injection port 33 integrally formed on it, aligned with the first injection port 2. A pull rod hook structure 34 that is movably engaged with the tension frame 51 is provided on one side of the lower surface of the upper mold 31 and one side of the upper surface of the lower mold 32. A faucet-shaped injection groove 52 is integrally formed on the upper surface of the lower mold 32. The upper surface of the lower mold 32 is also provided with A connecting groove 53 connects the second injection port 33 and the injection groove 52. A valve core seat insert 39, with its top end aligned with the valve core seat position in the injection groove 52, is detachably provided on the lower surface of the lower mold 32. The pull rod hook structure 34 consists of two pull rod structures symmetrically distributed on both sides of the upper surface of the lower mold 32. Each pull rod structure includes a swing rod 342 whose middle section is movably engaged with one side of the upper surface of the lower mold 32, and a pull rod 341 movably engaged with one end of the swing rod 342. The other end of the swing rod 342 is also provided with a hook 343 that can extend into the injection groove 52. In use, the mold is first placed on a flat platform. Then, the pull rod hook structure 34 is first installed on the lower mold 32, and the middle section of the swing rod 342 is movably engaged with the upper surface of the lower mold 32. Finally, the hook 343 is installed. One end of the swing rod 342 is inserted into the injection groove 52, while the other end is fitted with the pull rod 341. Then, the upper mold 31 and lower mold 32 of the inner mold 3 are closed and installed into the outer mold 1, aligning the first injection port 2 on the outer mold 1 with the second injection port 33 on the inner mold 3. The tension frame 51 is then movably engaged with the pull rod 341, and the tension frame 51 is connected to an external tension device, allowing it to be pulled by the tension device and slide along the connecting frame 51. Simultaneously, the valve core seat insert 39 is inserted below the lower mold 32. After the outer mold 1 and inner mold 3 are installed, the tension frame 51 is pulled back and forth by the tension device to pull the pull rod 341, thereby... Under the action of the lever 342, the hook 343 extends into the injection groove 52, and then hot melt plastic is injected from the first injection port 2. The hot melt plastic enters the second injection port 33 along the first injection port 2, and is guided by the connecting groove 53 to fill the injection groove 52. After the injection groove 52 is filled with hot melt plastic, since the injection groove 52 is shaped like a faucet, the injected hot melt plastic will also form a faucet shape. Under the action of the hook 343 and the valve core insert 39, a valve core seat and a curved water channel connected to the valve core seat are formed. After cooling, the pull rod 341 is pushed back and forth by an external pulling device to pull the hook 343, and the inner mold 3 and outer mold 1 are removed. The faucet part can be obtained by opening the upper mold 31 and the lower mold 32.The finished product is then obtained by drilling holes in the faucet's outlet pipe and grinding the edges. This eliminates the need for a sand core to shape the faucet and its internal water channels, resulting in fewer molding steps, lower production costs, and no additional sanding or other processing after molding. The molding process is therefore faster and simpler.

[0026] The lower mold 32 can also be detached and equipped with a second water outlet insert 35 with its top end aligned with the middle section of the water outlet pipe. This facilitates the rapid formation of the second water outlet in the middle section of the faucet's water outlet pipe through the second water outlet insert 35, giving the faucet a second water outlet and making it more functional.

[0027] Both the upper mold 31 and the lower mold 32 are provided with fixing holes 38, which facilitates the insertion of bolts and nuts through the fixing holes 38 to improve the connection between the upper mold 31 and the lower mold 32, and makes it less likely to generate gaps during injection molding, thus affecting the processing accuracy;

[0028] The upper mold 31 has several upper mold mounting holes 37 on its side wall, which makes it easier to quickly fix the upper mold 31 to the outer mold 1 by using bolts through the upper mold mounting holes 37. The fixing effect is better and it is not easy to shake or fall off.

[0029] The lower mold 32 has several lower mold mounting holes 321 on its side wall, which makes it easier to quickly fix the lower mold 32 to the outer mold 1 by using bolts through the lower mold mounting holes 321. The fixing effect is better and it is not easy to shake or fall off.

[0030] The lower mold 32 is also provided with an outlet insert 56 extending to the end of the outlet pipe of the injection tank 52;

[0031] The lower mold 32 is provided with a first slag discharge port 54 on both sides of the faucet body of the injection tank 52. This facilitates the discharge of excess hot melt plastic through the first slag discharge port 54. During injection, air in the injection tank 52 can be squeezed out through the first slag discharge port 54, thereby avoiding air bubbles in the finished product. It also reduces the pressure on the upper mold 31 and the lower mold 32 during injection, making it less likely for gaps to form between them during the injection process, which would affect the injection accuracy.

[0032] The lower mold 32 is provided with a second slag discharge port 55 on both sides of the water outlet pipe of the injection tank 52, which penetrates the lower mold 32 at the bottom. This helps to squeeze out the air in the injection tank 52 at the water outlet pipe during the injection process, thereby further avoiding air bubbles and improving the yield.

[0033] The lower surface of the outer mold 1 is also provided with a base 4. The bottom of the base 4 can be connected and fixed to the worktable by bolts, which helps to make the mold more stable when placed after it is closed, and it is not easy to cause skewing during injection molding.

[0034] The working principle of this utility model is as follows: First, the mold is placed on a flat platform. Then, a pull rod hook structure 34 is installed on the lower mold 32, and the middle section of the swing rod 342 is movably engaged with the upper surface of the lower mold 32. Next, a hook 343 is installed on one end of the swing rod 342, allowing it to extend into the injection groove 52. The other end of the swing rod 342 is inserted into the pull rod 341. Then, the upper mold 31 and lower mold 32 of the inner mold 3 are closed and inserted into the outer mold 1. In the inner mold, align the first injection port 2 on the outer mold 1 with the second injection port 33 on the inner mold 3, and connect the tension frame 51 and the pull rod 341 in a movable engagement. Connect the tension frame 51 to an external tension device so that it can be pulled by the tension device and slide along the connecting frame 51. Simultaneously, insert the valve core seat 39 below the lower mold 32. After the outer mold 1 and inner mold 3 are installed, first use the tension device to pull the tension frame 51 back and forth, causing it to pull the pull rod 341. 1. Then, under the action of the lever 342, the hook 343 extends into the injection groove 52, and then hot melt plastic can be injected from the first injection port 2, and the hot melt plastic enters the second injection port 33 along the first injection port 2. Through the guide of the connecting groove 53, the hot melt plastic fills the injection groove 52. After the injection groove 52 is filled with hot melt plastic, since the injection groove 52 is shaped like a dragon's head, the injected hot melt plastic will also form a dragon's head shape, and under the action of the hook 343 and the valve core seat insert 39... The valve core seat and the curved water channel connected to the valve core seat are formed. After cooling, the pull rod 341 is pushed back and forth to pull the hook 343 by the external pulling device, and the inner mold 3 and the outer mold 1 are removed. The faucet part can be obtained by opening the upper mold 31 and the lower mold 32. Then, the water outlet pipe of the faucet part is drilled and the edge is ground to obtain the finished product. There is no need to use a sand core to form the faucet and its internal water channel. The forming steps are few, the production cost is low, and there is no need for additional processes such as sanding after forming. The forming is faster and simpler.
