Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a casting mold for an engine bracket of a circulating water cooling mechanism. Background Art

[0002] A casting mold is a model used to create a qualified part. Ordinary hand-molding models often use wooden or plastic models, while mechanical models often use metal models, such as aluminum or iron. A casting mold is a pre-molded material made of other easily moldable materials to achieve the part's structural shape. The mold is then placed in a sand mold, creating a cavity with the same dimensions as the part's structure. A fluid liquid is then poured into this cavity, which, after cooling and solidifying, forms a part with the exact same shape and structure as the mold. With the development of the mold industry, more and more workpieces are being produced using casting processes. For example, engine parts and engine brackets are produced using casting molds. However, existing casting molds still present some problems.

[0003] There is an existing casting mold with good stability, such as the Chinese patent application number CN202120183273.X, in which a mounting top plate is arranged on the upper side of the operating platform, and a mounting bottom plate is arranged on the lower side of the operating platform. The mounting top plate and the mounting bottom plate are dynamically connected to the driving mechanism, an upper casting mold is fixed on the lower surface of the mounting top plate, a middle casting mold is fixed on the operating platform, and a lower casting mold is fixed on the upper surface of the mounting bottom plate, and the upper casting mold, the middle casting mold, and the lower casting mold are combined to form a casting cavity; a nesting clamping mechanism is installed on the lower side of the upper casting mold and the upper side of the lower casting mold, and a nesting groove is provided on the upper side and the lower side of the middle casting mold. When the upper casting mold, the lower casting mold and the middle casting mold are matched and combined, the clamping mechanism is nested and clamped in the nesting groove; however, the existing casting mold mainly relies on natural cooling when in use, but the efficiency of natural cooling is low, resulting in a long overall demoulding time, which leads to a relatively low overall production efficiency of the engine bracket.

[0004] Therefore, we propose an engine bracket casting mold for a circulating water cooling mechanism to solve the problems raised above. Utility Model Content

[0005] The purpose of the utility model is to provide an engine bracket casting mold with a circulating water cooling mechanism to solve the problem proposed in the above background technology that the existing casting mold relies on natural cooling and has low demoulding efficiency, resulting in relatively low production efficiency of the engine bracket.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a casting mold for an engine bracket of a circulating water cooling mechanism, comprising a base plate, a lower mold, and an upper mold:

[0007] A lower mold is fixed to the upper end of the bottom plate, and an upper mold is provided on the upper end of the lower mold, and the upper mold and the lower mold form a clamping structure, a circulation groove is provided on the inner wall of the lower mold, and a liquid storage tank is provided at the lower end of the lower mold, a first conduit is conductively connected between the upper end of the right side of the liquid storage tank and the circulation groove, and a second conduit is conductively connected between the upper end of the left side of the liquid storage tank and the circulation groove;

[0008] A sealing tube is provided inside the liquid storage tank, a piston is slidably connected inside the sealing tube, and a liquid outlet one-way valve is connected between the left side of the sealing tube and the second conduit;

[0009] An air guide groove is provided at the bottom end of the lower mold, an air guide plate is fixed inside the right side of the air guide groove, and an impeller is rotatably installed in the middle of the right side of the air guide groove.

[0010] Preferably, telescopic rods are fixed at the four corners of the upper end of the bottom plate, and the upper ends of the telescopic rods are fixedly connected to positioning plates, and the positioning plates are fixed to the outer wall of the upper mold.

[0011] By adopting the above technical solution, the upper mold can be supported by multiple sets of telescopic rods, and the accuracy of the engagement between the upper mold and the lower mold during casting can be improved.

[0012] Preferably, the circulation groove is opened around the outer wall of the lower mold, and the circulation groove is rectangular in design. The internal array of the circulation groove is provided with partitions, and the partitions are fixedly connected to the inner wall of the circulation groove, and conductive holes are symmetrically opened at the upper and lower ends of the partitions.

[0013] By adopting the above technical solution, the design of the circulation groove can facilitate the flow of internal liquid, thereby completing the heat dissipation and cooling of the mold, and the design of the partition can ensure the uniformity of the internal liquid flow.

[0014] Preferably, a reciprocating screw is rotatably connected inside the sealing tube, and the reciprocating screw is threadedly connected to the piston, a power motor is fixed inside the right end of the sealing tube, and the right end of the reciprocating screw is fixedly connected to the power motor, and a liquid inlet one-way valve is connected to the left end of the sealing tube, and the liquid inlet one-way valve is communicated with the inside of the liquid storage tank.

[0015] By adopting the above technical solution, through the cooperation between the reciprocating screw and the piston, the piston can be driven to reciprocate inside the sealing tube when it rotates, and during the movement, the liquid inside the liquid outlet tank is sucked into the sealing tube by the liquid inlet one-way valve, and then the liquid inside the sealing tube is transported to the circulation tank through the liquid outlet one-way valve.

[0016] Preferably, the air guide plates are symmetrically distributed on both sides of the impeller, and the upper end of the impeller is connected to a bevel gear set, and the upper end of the bevel gear set is fixedly connected to the reciprocating screw.

[0017] By adopting the above technical solution and designing the bevel gear set, the impeller can be driven to rotate synchronously with the rotation of the reciprocating screw, thereby increasing the air flow speed inside the air guide groove.

[0018] Preferably, filters are mounted on both ends of the air guide groove, and heat exchange plates are fixed to the inner wall of the upper end of the air guide groove, and the heat exchange plates are distributed in an equidistant array.

[0019] By adopting the above technical solution, the filter design prevents debris from entering the air guide groove, and the design of the heat exchange plate can take away heat when the air flows, thereby accelerating the heat dissipation of the liquid inside the liquid storage tank.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the engine bracket casting mold of the circulating water cooling mechanism;

[0021] 1. The water circulation structure can continuously cool the mold using the circulating liquid, thereby increasing the overall cooling rate, indirectly improving the demoulding and production efficiency of the engine bracket during the casting process. The air cooling structure is also used to accelerate the heat dissipation of the coolant, further accelerating the cooling effect of the mold.

[0022] 2. By connecting the water circulation structure and the impeller, the impeller can be used to drive the air to flow at high speed inside the air guide groove while supplying water to the water circulation structure, thereby accelerating the heat dissipation of the liquid inside the liquid storage tank. The design of a single power source not only reduces costs, but also reduces the failure rate of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS
