Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold device for a centralized water supply facility. Background Technology

[0002] In modern molding and processing fields such as plastic injection molding and metal die casting, mold temperature control is one of the key factors that determine product quality, production efficiency and mold life. In order to effectively remove the huge amount of heat generated during the molding process and ensure that the mold works at a stable and suitable temperature, the mold is usually designed with a complex cooling water channel system.

[0003] Traditional mold cooling systems often employ a decentralized connection method, where external cooling water sources are connected one by one to the inlets and outlets of the cooling water channels in the upper and lower molds via multiple independent hoses or metal pipes. However, this decentralized cooling connection method has many significant drawbacks. For large or complex molds with numerous cooling loops, dozens of water pipes need to be connected. During on-site installation, operators need to identify and connect the inlets and outlets one by one, a cumbersome and time-consuming process that is prone to misconnection. Therefore, a mold forming device with a centralized water supply facility is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A molding device for a centralized water supply facility, comprising: Lower mold; The upper mold is positioned above the lower mold; Multiple sets of water collection valves are respectively installed on the upper mold and the lower mold, and are used to connect the water inlet or outlet of the cooling channel of the upper mold or the lower mold respectively. Each water collection valve includes a valve body, a main pipe connected to one end of the valve body, and multiple water distribution pipes connected to the valve body. The water distribution pipes are connected to the water inlet or outlet of the upper mold or the lower mold.

[0005] As an improvement to the above solution, a regulating valve is installed on the main pipe.

[0006] As an improvement to the above solution, multiple sets of threaded rods are movably inserted into the valve body, and the end of the threaded rod away from the valve body is threadedly connected to the upper or lower mold.

[0007] As an improvement to the above solution, a plug is threaded into the end of the valve body away from the main pipe.

[0008] The beneficial effects of this utility model are: By setting water inlet and outlet valves on the upper and lower molds respectively, and using the main pipe of the water inlet valves to achieve the main connection with the external cooling system, the number of scattered connection points that could originally be as many as dozens is drastically reduced. This greatly simplifies the connection operation between the mold and the cooling system, making the installation and disassembly process extremely quick and convenient, effectively avoiding the risk of misconnection, significantly shortening the mold change time, and significantly improving the flexibility and production efficiency of the production line.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] A molding device for a centralized water supply facility, comprising: Lower mold 10; Upper mold 20 is disposed above the lower mold; Multiple sets of water collection valves 30 are respectively installed on the upper mold 20 and the lower mold 10, and are used to connect to the water inlet or outlet of the cooling channel of the upper mold 20 or the lower mold 10 respectively. Each water collection valve 30 includes a valve body 31, a main pipe 35 connected to one end of the valve body 31, and multiple water distribution pipes 34 connected to the valve body 31. The water distribution pipes 34 are connected to the water inlet or outlet of the upper mold or the lower mold.

[0013] Specifically, during mold closing, the upper mold 20 and lower mold 10 close together to form a complete cavity. During mold opening, the upper mold moves with the moving template to achieve demolding. Four sets of water collection valves 30 are provided: two sets on the upper mold 20 and two sets on the lower mold 10. One set of water collection valves 30 is used for water inlet to the cooling channel, and the other set is used for water outlet to the cooling channel. Each water circuit contains a complete loop of "water inlet water collection valve 30 - cooling channel - water outlet water collection valve 30". When the water collection valve 30 is used for water inlet, the main pipe 35 of the valve body 31... The multi-component water pipes 34 are connected to the outlet of the external chiller and correspond one-to-one with the inlet of the cooling channel. When the water collection valve is used for water discharge, the main pipe 35 of the valve body 31 is connected to the return water port of the external chiller. The multi-component water pipes 34 correspond one-to-one with the outlet of all cooling channels of the upper mold 20 or the lower mold 10. The low-temperature cooling water in the cooling channels of the upper mold 20 and the lower mold 10 absorbs the heat from the outer wall of the cavity through heat exchange. As the heat is continuously carried away, the temperature of the molten material in the cavity drops rapidly, gradually solidifying from a softened state, and finally shaping into a product that is completely consistent with the shape of the cavity. The main pipe 35 of the water collection valve is used to realize the main connection with the external system, and the multi-component water pipes are used to realize the connection with the numerous cooling circuits inside the mold, which greatly simplifies the on-site pipeline layout and reduces the risk of confusion and incorrect connection.

[0014] In one embodiment, a regulating valve 36 is installed on the main pipe 35, enabling the operator to independently regulate the water inflow and return back pressure of the upper mold 20 and the lower mold 10, which is the basis for achieving uniform and stable control of the mold temperature field.

[0015] In one embodiment, multiple sets of threaded rods 32 are movably inserted into the valve body 31. The end of the threaded rod 32 away from the valve body 31 is threadedly connected to the upper mold 20 or the lower mold 10. During the mold assembly stage, the threaded rod 32 of the water collecting valve 30 is aligned with the threaded hole reserved on the upper mold 20 or the lower mold 10, and the threaded rod 32 is screwed into the threaded hole of the upper mold 20 or the lower mold 10 and tightened, thereby firmly and detachably fixing the water collecting valve 30 to the designated position of the upper mold 20 or the lower mold 10. When cleaning, maintenance or replacement of the water collecting valve is required, the threaded rod 32 can be unscrewed to easily remove the entire water collecting valve 30 from the mold, making maintenance extremely convenient. The water collecting valve 30 becomes a complete module that includes fixing, connecting and adjusting functions. When designing the mold, only standard threaded hole positions and cooling water inlets need to be reserved to quickly integrate this module, which greatly improves the standardization of mold design and manufacturing efficiency.

[0016] In one embodiment, a plug 33 is threaded onto the end of the valve body 31 away from the main pipe 35. The threaded design of the plug 33 makes it a removable access port. When it is necessary to clean the internal flow channel of the water collection valve 30, such as to remove scale, impurities, or for inspection, simply unscrew the plug 33 from the valve body 31. After opening this port, special tools can be used to thoroughly clean and inspect the flow channel of the valve body 31, the connection of the water distribution pipe 34, and even the area near the main pipe 35 from the inside. This is crucial for ensuring the long-term smooth flow of the cooling water circuit, preventing blockages, and maintaining optimal cooling efficiency. After maintenance, simply tighten the plug 33 again.

[0017] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
