Technical Field

[0001] This utility model relates to the field of sand core manufacturing technology, and in particular to an inorganic mold preheating station. Background Technology

[0002] In the field of inorganic core making in the foundry industry, inorganic core making equipment is used with inorganic molds for the production of inorganic sand cores. The inorganic process uses heating to dehydrate and harden the molding sand. Oil heating is a common method for heating inorganic molds, and the mold temperature needs to be heated to the range of 150-250℃ during normal production. Before starting production each day, the mold needs to be installed on the core making machine in advance, and then production can begin after the mold has been heated to the set process temperature.

[0003] In actual production, it generally takes more than an hour from mold installation to heating to the set temperature. During this time, the core-making equipment is idle and cannot produce products. The excessively long production preparation process affects the efficiency of equipment use and overall production efficiency. Utility Model Content

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] Example 1

[0026] like Figure 1 As shown, an inorganic mold preheating station is located on one side of a core-making machine, close to the machine, or in a centralized mold hoisting area for easy handling. The preheating station includes an oil temperature controller 1, a fixed base 2, a connecting hose 3, and a protective mechanism 4. The fixed base 2 is used to place the mold 5. The oil temperature controller 1 is located on one side of the fixed base 2, with an inlet pipe 11 and an outlet pipe 12 on one side. The inlet pipe 11 and outlet pipe 12 are respectively connected to the upper and lower molds of the mold 5, or the inlet pipe 11 and outlet pipe 12 can be connected to the lower and upper molds of the mold 5, forming a circulation loop between the upper and lower molds. The two ends of the connecting hose 3 are also connected to the upper and lower molds of the mold, respectively. The inlet pipe 11, outlet pipe 12, mold 5, and connecting hose 3 form a preheating circulation loop. The protective mechanism 4 is arranged around the oil temperature controller 1 to protect it and improve the safety of the operator.

[0027] like Figure 1 As shown, gate valves 13 are installed on both the inlet pipe 11 and the outlet pipe 12 to control the inflow and outflow of oil. Furthermore, the connection ends of the inlet pipe 11, the outlet pipe 12, and the connecting hose 3 to the mold are all equipped with self-sealing quick-connect fittings 31. These quick-connect fittings 31 provide good sealing and are convenient and quick to connect; for example, a fitting with model number 1-11-012-0-WR526-AAAG. In addition, in this embodiment, all pipes and hoses are wrapped with heat-insulating protective sleeves.

[0028] The protective mechanism 4 includes a guardrail that fully or partially surrounds the oil temperature controller 1. In this embodiment, as shown... Figure 1 As shown, the guardrail partially surrounds the oil temperature controller 1, and surrounds the oil inlet and outlet sides of the oil temperature controller 1.

[0029] like Figure 1As shown, the guardrail is provided with inspection doors 41 on both sides near the oil inlet and outlet of the oil temperature controller 1. The inspection doors 41 can be opened and are locked for easy maintenance. The guardrail is provided with a baffle 42 on the side near the fixed base 2 to prevent the risk of burns caused by oil leakage.

[0030] The guardrail is also equipped with a placement seat 43, specifically located on the outside of the baffle 42. The placement seat 43 has multiple connector sockets 44 that mate with quick-connect connectors 31. The quick-connect connectors 31 at the connection ends of the liquid inlet pipe 11, the liquid outlet pipe 12, and the connection end of the connecting hose 3 can all be connected to the connector sockets 44, thereby hanging them on the placement seat 43, making the pipes neat and tidy, and facilitating the disassembly and assembly of the pipes during heating.

[0031] like Figure 1 As shown, a plurality of limiting members 21 are provided above the fixed base 2, and the plurality of limiting members 21 are arranged around the periphery of the mold 5 to limit the position of the mold. In this embodiment, the limiting members 21 are angle irons, arranged around the four corners of the mold 5.

[0032] Example 2

[0033] Based on the structure of Example 1, such as Figure 2 As shown, there are multiple connecting hoses 3, which are connected to multiple molds 5 one by one; the liquid inlet pipe 11 and the liquid outlet pipe 12 are connected to the upper mold and lower mold of the mold 5 through a flow divider assembly, which includes a multi-way valve 61 and multiple flow divider pipes 62.

[0034] Before production, the mold to be produced is moved to the fixed base 2, and the connecting ends of the liquid inlet pipe, the liquid outlet pipe, and the connecting ends of the connecting hose 3 are connected to the interfaces of the upper and lower molds to form a preheating circulation loop. The oil temperature controller is turned on to heat the mold 5. Generally, the preheating temperature is set to about 80°C to avoid burns to the operators during the transfer of the high-temperature mold to the core-making machine. After heating to the set temperature, the quick-connect plugs of the liquid inlet pipe, the liquid outlet pipe, and the connecting hose are disconnected and placed on the placement seat. Then, the mold is hoisted to the core-making machine.

[0035] In summary, this utility model has a simple structure and is easy to operate; the mold is preheated to a certain temperature in advance, which does not occupy production time. During production, it is only necessary to heat from the preheating temperature to the process temperature, which shortens the heating time, saves the mold heating waiting time, and improves the utilization rate of equipment and production capacity. In addition, this utility model can realize the preheating of multiple molds at one time by configuring multiple sets of pipelines, and can be adapted to one or more mechanical core machines. At the same time, this utility model is also suitable for the hot mold matching needs of molds.
