Description

Technical Field

[0001] The invention belongs to the technical field of core shooting machines, and in particular relates to a manual mold core shooting integrated machine. Background Art

[0002] Core shooters are widely used in the foundry industry. The cores made by core shooters are accurate in size and smooth in surface. The working principle of core shooters is to shoot the core sand mixture with liquid or solid thermosetting resin as binder into the heated core box. The sand core is preheated in the core box and quickly hardens to a certain thickness before being taken out, forming a high-quality sand core product with smooth surface and accurate size.

[0003] Core shooting machines have been widely used in recent years because they can reduce the waste of pouring heads by stacking multiple boxes for casting. The coated sand after casting has good disintegration properties, which is conducive to sand cleaning. The sand mold size is precise, which can appropriately reduce the processing volume. The operation is easy and the casting yield is high, so more foundries prefer to use core shooting machines for molding.

[0004] In the prior art, the core shooting machine does not have an automatic unloading function, and the unloading speed is slow, which seriously affects the core making efficiency.

[0005] In Chinese patent literature, there is a patent document with the publication number CN 212144420 U, named core shooting machine, which solves the above problems. The utility model discloses a core shooting machine, including a core shooting machine body, a lower mold is arranged on the working table of the core shooting machine body, and a sand shooting mechanism is arranged on both sides of the lower mold. The upper mold moves up and down with the push plate to approach or move away from the lower mold; it also includes a lifting mechanism and a conveying mechanism; the lifting mechanism includes a base, a driving device, a lifting platform and a four-link, the base is arranged on the side of the core shooting machine body, the upper and lower ends of the four-link are respectively hinged to the lifting platform and the base, one end of the driving device is hinged to the base, and the other end is hinged to the side of the four-link away from the core shooting machine body, when the driving device pushes the four-link to the limit position, the lifting platform is located above the lower mold, and when the driving device pulls the four-link to the limit position, the lifting platform is located and moves downward and toward the outside of the core shooting machine body. The utility model has the function of automatic unloading, speeds up the unloading speed, and greatly improves the efficiency of core making.

[0006] However, the above patent documents require other heating equipment to heat the mold. After the mold is heated, the transfer temperature is likely to drop, which not only causes energy loss, but also affects the quality and efficiency of sand injection molding. How to quickly transfer to ensure that the temperature of the mold does not drop, improve the quality of the sand mold, reduce the molding time, and reduce energy loss, this is a technical problem that we urgently need to solve.

[0031] Preferably, a circulating water tank 12 for circulating water to the water-cooling track 3 is provided at the lower rear side of the water-cooling track 3 .

[0032] During operation, the water supply valve of the circulating water tank 12 of the water-cooling track 3 is started to allow cold water to circulate in the water-cooling track 3 to ensure that the temperature of the water-cooling track 3 does not rise excessively when the mold 1 is heated; the mold 1 including the upper mold or the lower mold is lifted by a forklift or a lifting machine to the preparatory position of the water-cooling track 3, the ignition switch of the gas heating burner 5 is started, and it is ensured that the gas is continuously supplied, and the gas heating burner 5 heats the mold 1; at the same time, the electric heating device of the mold electric heating plate 2 is started to ensure that the temperature of the mold electric heating plate 2 rises to a predetermined temperature; when the mold 1 is heated to the predetermined temperature, the gas heating burner 5 stops heating, and the moving device of the mold 1 is started to move the mold 1 to the sand shooting position, the mold closing cylinder 6 is started, the mold electric heating plate 2 is pushed upward to position and close the mold with the mold 1, the cylinder 10 is started, and the sand shooting tube 4 on the moving plate 9 is moved from the sand injection position to the sand shooting position.
