Problems solved by technology

[0003] At present, most of the existing core shooting machines are designed in one piece, and it is difficult to realize complete automation of core shooting, curing, demoulding and other processes; the structural design of the mold makes the mold clamping accuracy of the mold poor after the core is demoulded, which affects the core. Quality; the traditional demoulding process cannot use cores with complex shapes and structures, and the cores are often damaged and cannot be used when demoulding; receiving cores is also manual, so the degree of automation is low, and the demand for manpower is large. high cost

Embodiment Construction

[0024] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings.

[0025] The automatic core shooter of this embodiment, through the PLC (programmable logic controller) control system, automatically controls the drive motor of each device and the air pressure valve of the air pressure system to complete the operation of the whole machine.

[0026] Such as Figure 1 to Figure 7 The fully automatic core shooting machine shown in this embodiment includes a hopper 11, a mold and a core shooting device 2 for injecting core sand into the mold. The mold is divided into an upper mold 301, a middle mold 302 and a lower mold 303. The mold The opposite sides are provided with a locking mechanism that controls the opening and closing of the middle mold 302 and the lower mold 303; the automatic core shooter also includes: a curing device, which includes a curing frame 401, an air blowing mechanism 404 and a mold splitting mechanism...

Abstract

The invention relates to a fully automatic core shooting machine, which includes a mold and a core shooting device for injecting core sand into the mold. The mold is divided into an upper mold, a middle mold and a lower mold. The locking mechanism for the opening and closing of the middle mold and the lower mold. The fully automatic core shooter also includes: a curing device, which includes a curing frame, an air blowing mechanism and a parting mechanism; a demoulding device, which includes a demoulding frame, a lifting mechanism for lifting the mold, and flipping the lifted mold The overturning mechanism and the ejection mechanism for demoulding the core in the mold; the moving device, which is driven by a servo motor, makes the mold accurately position or move back and forth horizontally in the positions of the core shooting device, curing device, and demoulding device; A material receiving device, which is used to automatically transport the core obtained from the demoulding device; a PLC control system, which controls each drive in the core shooting device, curing device, demoulding device, moving device, and material receiving device Motor and cylinder for automatic operation.

Description

technical field [0001] The invention relates to the field of molding equipment for casting molding, in particular to a fully automatic core shooter for manufacturing cores with cold boxes. Background technique [0002] Core shooters are widely used in the foundry industry and are suitable for both hot and cold core boxes. The working principle of the core shooting machine is to shoot the core sand mixture with liquid or solid thermosetting resin as the binder into the core box mold, and take out the core sand after hardening in the mold to obtain the core. At room temperature, the core-making method in which the sand core is rapidly hardened and formed in the core box by blowing air is called the cold box method. Cold box is a high-efficiency manufacturing process for sand cores. It has the advantages of high efficiency, energy saving, and good working conditions. It has been widely used in foundry production. [0003] At present, most of the existing core shooting machine...
