Detailed Implementation

[0024] 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.

[0025] like Figure 1-4 As shown:

[0026] A mold for producing a three-way water inlet pipe for a washing machine includes a first mold 101 and a second mold 102. Guide posts are fixedly installed at the four corners of the first mold 101, and guide grooves adapted to the guide posts are formed at the four corners of the second mold 102, serving a positioning and guiding function. When the first mold 101 and the second mold 102 are closed, a cavity 103 is formed inside. The mold also includes:

[0027] First core 104, second core 105 and third core 106; the first core 104, the second core 105 and the third core 106 are all set on the second mold 102, and can form the core of the three-way water inlet pipe;

[0028] When the first mold 101 and the second mold 102 are closed, a movable cavity adapted to the first core 104, the second core 105 and the third core 106 is provided inside, and a sealing sleeve is provided inside the movable cavity to increase the sealing between the first core 104, the second core 105 and the third core 106 and the movable cavity.

[0029] A drive mechanism 2, mounted on the second mold 102, is used to drive the first core 104, the second core 105, and the third core 106 to move and reset to achieve demolding. The drive mechanism 2 includes a first hydraulic push rod 201 mounted on the second mold 102, one end of the third core 106 fixedly mounted on the output end of the first hydraulic push rod 201, and a third hydraulic push rod 203 also mounted on the second mold 102. One end of the first core 104 is fixedly mounted on the output end of the third hydraulic push rod 203, and a second hydraulic push rod 202 is mounted on the top of the second mold 102. One end of the second core 105 is fixedly mounted on the output end of the second hydraulic push rod 202. The first hydraulic push rod 201, the second hydraulic push rod 202, and the third hydraulic push rod 203 are all fixedly connected to the second mold 102 through a mounting plate.

[0030] The ejection mechanism 3, installed on the second mold 102, works in conjunction with the drive mechanism 2 to eject and unload the product. The ejection mechanism 3 includes an ejection module 301 sliding within the second mold 102 and connecting plates 302 fixed to both ends of the ejection module 301. Multiple sets of equidistant telescopic rods 304 are fixed between the connecting plates 302 and the mounting plate. Springs 303 are wound around the surface of the telescopic rods 304, with both ends of the springs 303 fixedly connected to the mounting plate and the connecting plate 302 respectively. The two sets of connecting plates 302 are connected on one side to each other. At the far end, a lever 306 is fixed. The two sets of levers 306 are symmetrically arranged and inclined. L-shaped rods 305 are fixedly installed on the output end surfaces of the third hydraulic push rod 203 and the first hydraulic push rod 201. The second mold 102 has a placement groove that matches the release module 301. The second mold 102 also has a rectangular opening that matches the connecting plate 302. The connecting plate 302 can move within the rectangular opening, and the rectangular opening is connected to the placement groove. The spring 303 is in a compressed state.

[0031] The second mold 102 has an injection port on the side away from the first mold 101.

[0032] In this embodiment: During use, one side of the mold for producing the three-way water inlet pipe of the washing machine can be connected to the drive component (hydraulic telescopic cylinder) to drive the closing or separation of the first mold 101 and the second mold 102. The second mold 102 is fixedly installed on the equipment and has a material injection port on one side. It is connected to the material injection port through a material injection device (not shown in the figure) so that material can be injected into the cavity 103 when the first mold 101 and the second mold 102 are closed.

[0033] At the same time, the first hydraulic push rod 201, the second hydraulic push rod 202 and the third hydraulic push rod 203 respectively drive the third core 106, the second core 105 and the first core 104 to be partially inserted into the cavity 103. The cavity diameter of the cavity 103 is larger than the diameter of the moving core, thereby forming a gap between the cavity 103 and the first core 104, the second core 105 and the third core 106. This gap is the shell of the three-way water inlet pipe.

[0034] After sufficient material is injected into the cavity 103 to completely fill the gap, the product is cooled by the cooling system (not shown in the figure) built into the first mold 101 and the second mold 102. After cooling is completed, the first mold 101 is driven to separate from the second mold 102. At the same time, the first hydraulic push rod 201, the second hydraulic push rod 202 and the third hydraulic push rod 203 are activated to drive the third core 106, the second core 105 and the first core 104 to reset and detach them from the product. During this process, the third core 106, the second core 105 and the first core 104 slide in the movable cavity opened in the second mold 102 and move out of the cavity 103.

[0035] As the first hydraulic push rod 201 and the third hydraulic push rod 203 retract, their output ends drive the L-shaped rod 305 to move synchronously. The L-shaped rod 305 moves into the gap between the lever 306 and the connecting plate 302. The lever 306 is set to be inclined. In this way, the L-shaped rod 305 can drive the lever 306 to move in the direction of the third hydraulic push rod 203 or the first hydraulic push rod 201.

[0036] The movement of lever 306 drives the connecting plate 302 to move, while the traction spring 303 and telescopic rod 304 are stretched, thereby driving the removal module 301 to move. The removal module 301 extends out from the placement slot in the second mold 102 and pushes the three-way water inlet pipe product out of the second mold 102, completing the unloading operation.

[0037] Subsequently, the first mold 101 is driven and re-fits with the second mold 102. At the same time, the first hydraulic push rod 201, the second hydraulic push rod 202 and the third hydraulic push rod 203 respectively drive the third core 106, the second core 105 and the first core 104 to be re-inserted into the cavity 103. During this process, the compression on the lever 306 is released, and the spring 303 resets due to its elasticity, driving the demolding module 301 and the connecting plate 302 back to their initial positions, preparing for the next demolding.

[0038] This solution employs an innovative stripping mechanism design, eliminating the need for a separate drive system. This reduces energy consumption, lowers production costs, and aligns with green manufacturing and sustainable development requirements. By eliminating additional drive units, it also reduces potential sources of mold failure, lowers the probability of downtime for maintenance, and improves production continuity and efficiency. This design significantly enhances the mold's performance.

[0039] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet (with a controller installed inside). The electrical control cabinet is installed on the equipment. During use, each piece of electrical equipment can be started and operated through the electrical control cabinet. The power connection method of each piece of electrical equipment is a mature existing technology and is well known to those in the field. It will not be described in detail here.

[0040] The controller can control the stroke trajectories of the first hydraulic push rod 201, the second hydraulic push rod 202 and the third hydraulic push rod 203 to be different, while ensuring that the drive lever 306 presses the lever 306 synchronously. The specific control design can be flexibly designed according to the actual design requirements.

[0041] Meanwhile, the contents of the cooling system not described in detail in this specification are all prior art known to those skilled in the art and can be used as a reference for the present technology. For details, please refer to CN204997876U.

[0042] Furthermore;

[0043] In an optional embodiment, a sleeve 307 is rotatably mounted on the surface of the L-shaped rod 305 via a bearing.

[0044] In this embodiment: Since a sleeve 307 is rotatably mounted on the surface of the L-shaped rod 305 via a bearing, when the L-shaped rod 305 applies pressure to the lever 306, the sleeve 307 can rotate on the surface of the L-shaped rod 305 due to friction. The sleeve 307 reduces the friction between the L-shaped rod 305 and the lever 306, making the movement of the L-shaped rod 305 smoother.

[0045] The working principle and usage process of this utility model are as follows: During use, the first mold 101 is connected to the hydraulic telescopic cylinder and driven to close with the second mold 102. The second mold 102 is provided with a material injection port. The material injection device injects material into the cavity 103 through the material injection port. The first hydraulic push rod 201, the second hydraulic push rod 202 and the third hydraulic push rod 203 respectively drive the third core 106, the second core 105 and the first core 104 to be partially inserted into the cavity 103, forming the shell gap of the three-way water inlet pipe. After the material is filled, the built-in cooling system cools the product. After cooling, the first mold 101 separates from the second mold 102. The first hydraulic push rod 201, the second hydraulic push rod 202, and the third hydraulic push rod 203 respectively drive the third core 106, the second core 105, and the first core 104 to separate from the cavity 103. At the same time, as the first hydraulic push rod 201 and the third hydraulic push rod 203 retract, their output ends drive the L-shaped rod 305 to move synchronously. The L-shaped rod 305 moves into the gap between the lever 306 and the connecting plate 302. The lever 306 is set to be inclined, so that the L-shaped rod 305 can drive the lever 306 to move in the direction of the third hydraulic push rod 203 or the first hydraulic push rod 201. The movement of the lever 306 drives the connecting plate 302 to move, and at the same time, the traction spring 303 and the telescopic rod 304 are stretched, thereby driving the demolding module 301 to move. The demolding module 301 extends out from the placement groove opened in the second mold 102, and pushes the three-way water inlet pipe product out of the second mold 102, completing the demolding operation.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
