CN201128278Y - Laser marking system for casting sand core - Google Patents

Abstract

The utility model discloses a cast sand core laser marking machine which includes a laser marking machine, a sand core and a work bench; the sand core is arranged on the work bench; the positioned on the sand core to be marked is aligned with the laser radiating position of the laser marking machine. During use, the sand core is first arranged on the work bench; and then the laser marking machine is set, the current is increased, a marking button is pressed, the laser marking machine emits large-power laser beams, the laser beams are radiated on the sand core, to burn and sand and resin on the sand core which then fly up and form characters or patterns in a pit. The sand core is taken as a mould and cast into protruded characters or patterns needed. The cast sand core laser marking machine of the utility model has the advantages of high automation degree, very high speed, clear font, neatness, completeness, elegance, standardization, etc., and can greatly reduce the labor intensity and improves the production efficiency.

Description

The casting sand core laser marking system

Technical field

The utility model relate to a kind of on casting sand core the system of engraving character or pattern, particularly adopt the system of laser marking machine engraving character or pattern on casting sand core.

Background technology

Need cast out literal or pattern in many casting techniques on foundry goods, at present, casting technique casts out literal on foundry goods or pattern all is to adopt mould or hand engraving to form concave sections to obtain moulding, forms literal or the pattern that protrudes at cast(ing) surface.Formed in mould shortcoming is: adopt mould molding literal or pattern to be difficult to change, flexibility is bad, and incompatibility is used for foundry goods and forms casting number (serial number); The shortcoming of offhand is: font or dim design, irregular, imperfect, not attractive in appearance, lack of standardization, carve mistake easily, difficult location, labour intensity height.

Laser marking machine is extensive in sector applications such as five metals, electronics, instrument, medicine, can be used for meticulous mark, pattern, literal and the half-tone etc. of engraving on the materials such as metal, plastics, rubber, timber, glass, marble, leather, seal.But because sand hardness height, the fusing point height (far above the fusing point of iron) of casting sand core are not used for casting field with laser marking machine before the application.

Summary of the invention

The utility model provides a kind of casting sand core laser marking system, utilizes laser marking machine engraving character or pattern on casting sand core, has overcome the deficiency of present mould or hand engraving mode.

The utility model casting sand core laser marking system comprises laser marking machine, core and workbench, and core is arranged on the workbench, and core needs the laser beam irradiation position of the position alignment laser marking machine of mark.

In the technical solution of the present utility model, mainly (main chemical compositions is SiO by sand owing to casting sand core ₂) and the resin composition, therefore hardness height, intensity height, fusing point height need to adopt high power laser mark machine, and electric current generally needs 10～25A.Laser marking machine generally comprises the computer operation control system.Utilize high energy laser beam that powerful laser marking machine sends the resin scaling loss on the core, discrete font or the pattern that flies out and afterwards forms pit of this position sand done mould and poured into a mould with carving core well, casts out the literal or the pattern of protrusion moulding.

The beneficial effects of the utility model are: automaticity height, speed are very fast, and font is clear, neat, complete, attractive in appearance, standard.Greatly reduce labour intensity, improved production efficiency.Can be applied to casting techniques such as foundry machinery part, casting technique product.

Description of drawings

Fig. 1 is the utility model casting sand core laser marking system structure chart.

In the accompanying drawing: 1-core, 2-workbench, 3-laser marking machine.

The specific embodiment

Further specify the utility model structure and using method below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model casting sand core laser marking system comprises core 1, workbench 2 and laser marking machine 3.During use, at first core 1 is placed on the workbench 2, sets laser marking machine 3 then, electric current is transferred greatly, and by the mark button, laser marking machine 3 sends powerful laser beam, laser beam is got on the core 1, sand on the core and resin scaling loss and fly out, forms the font or the pattern of pit.This core is done the mould cast, casts out the literal or the pattern of required protrusion moulding.

Claims (4)

1, a kind of casting sand core laser marking system is characterized in that: comprise laser marking machine, core and workbench, core is arranged on the workbench, and core needs the laser beam irradiation position of the position alignment laser marking machine of mark.

2, according to the described casting sand core laser marking system of claim 1, it is characterized in that: casting sand core mainly is made up of sand and resin.

3, according to claim 1 or 2 described casting sand core laser marking systems, it is characterized in that: the electric current of laser marking machine is 10～25A.
