Technical Field

[0001] This utility model relates to the field of molds, and in particular to a hot press mold for a faucet bend. Background Technology

[0002] Ceramic faucets are gradually becoming a replacement for metal faucets due to their corrosion resistance, but they still face technical bottlenecks in manufacturing processes. Traditional metal faucets commonly suffer from oxidation and rust defects, while ceramic faucets manufactured using slip casting processes have insufficient density in the preform due to the characteristics of the process, making them prone to damage during demolding and thus reducing their service life. Utility Model Content

[0003] The purpose of this invention is to provide a hot press mold for faucet bends that is easier to demold.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A hot-press injection mold for a faucet bend includes a mold body consisting of an upper mold and a lower mold, which can be snapped together. The mold body further includes a mold core assembly. A mold cavity adapted to the faucet bend is formed between the upper and lower molds. The mold cavity includes an arc-shaped segment and a vertical segment connected to each other. The mold body has a first inlet communicating with the free end of the arc-shaped segment and a second inlet communicating with the free end of the vertical segment. The mold core assembly includes a first mold core and a second mold core. The second mold core is adapted to the vertical segment and can be inserted into the vertical segment of the mold cavity from the second inlet. The first mold core is adapted to the arc-shaped segment and can be inserted into the arc-shaped segment of the mold cavity from the first inlet. The first and second mold cores inserted into the mold cavity are detachably connected.

[0006] By adopting the above technical solution, the first mold core and the second mold core can be detachably inserted, which makes it easier to separate the first mold core and the second mold core from the first inlet and the second inlet respectively when demolding, while ensuring the integrity of the faucet after it is made.

[0007] The first mold core includes a first end and a second end. A drawing section extending out of the mold body is formed on the first end, and an insertion hole is formed on the second end. An insertion section adapted to the insertion hole is formed on the upper end of the second mold core.

[0008] By adopting the above technical solution, when it is necessary to remove the first mold core from the mold body, the mold removal section extending outside the body can be pulled to make it easier for the first mold core to detach from the mold body. The interlocking hole and the interlocking section can cooperate to make the first mold core and the second mold core more stably connected and prevent displacement during use.

[0009] The cross-section of the first mold core is circular, and the diameter gradually decreases from the first end to the second end.

[0010] By adopting the above technical solution, the diameter gradually decreases from the first end to the second end, making it easier to detach the first mold core.

[0011] The extraction section has perforations for inserting auxiliary demolding tools.

[0012] By adopting the above technical solution, during demolding, auxiliary demolding tools such as pins can be inserted into the perforations to make the first mold core easier to demold.

[0013] It also includes a fixing base, and the lower end of the second mold core is connected to the fixing base.

[0014] By adopting the above technical solution, a fixed base is connected to the lower end of the second mold core, which makes the second mold core more stable during use and prevents it from shifting.

[0015] The cross-section of the second mold core is circular, and the diameter of the second mold core gradually decreases from the bottom to the top.

[0016] By adopting the above technical solution, the diameter of the second mold core gradually decreases from the bottom to the top, which facilitates the demolding of the second mold core and prevents it from getting stuck in the mold cavity.

[0017] The top surface of the fixed base has a plurality of positioning parts, and the mold body has positioning grooves that are adapted to the positioning parts.

[0018] By adopting the above technical solution, the positioning part and the positioning groove can be quickly aligned, shorten the mold assembly time, avoid incorrect installation direction of the fixed seat, improve production safety, and further improve the stability during use.

[0019] It also includes a third mold core, which has an axially extending clearance hole through which the drawing section passes, so that the third mold core can be fitted onto the drawing section and close the first entrance. The third mold core includes a threaded section located in the arc-shaped section of the mold cavity, and the outer peripheral surface of the threaded section has an external thread.

[0020] By adopting the above technical solution, the clearance hole can facilitate the assembly of the third mold core and the mold drawing section, while the thread forming section can give the faucet outlet a threaded structure after production, so as to facilitate the subsequent addition of interfaces.

[0021] It also includes a limiting member, on which a screw hole is formed, and the third mold core includes a fixed section that is threadedly engaged with the screw hole, and the outer peripheral surface of the fixed section is formed with an external thread that is engaged with the screw hole.

[0022] By adopting the above technical solution, the limiting component and the third mold core are fixed by threaded connection, and the displacement of the third mold core is restricted.

[0023] The upper and lower molds are provided with a plurality of oppositely arranged positioning holes and / or screw holes, which allow the upper and lower molds to be engaged relative to each other by fasteners.

[0024] By adopting the above technical solution, the positioning holes ensure the alignment of the upper and lower mold cavities, avoiding flash caused by misalignment, and the screw holes, together with the fasteners, enable quick opening and closing, improving maintenance efficiency.
