Abstract
The utility model relates to an x-ray conformal chock block moulding mould, which is used for manufacturing a medical X-ray conformal lead chock block and is mainly composed of a bottom plate and a steel manufacture moulding template. The utility model is characterized in that the template is designed into four blocks, four blocks of templates enclose into a vertical type moulding hollow cavity on the bottom plate, a press plate is arranged on the moulding hollow cavity in a slide mode and each template is also provided with a positioning slide block. When moulding is conducted, a medical lead chock block of a needed shape can be manufactured combining with a foam mould core, the templates are mutually adsorbed, combination is tight, clamping assembly is firm without split and reverse plate phenomena, the quality of the manufactured lead chock block is reliable and stable and the displacement phenomenon of the mould core and a conformal figure is prevented from occurring. The utility model has the effects of simple structure, convenient use and high manufacture efficiency and product rate.
Description
Technical field
The utility model belongs to medical apparatus, particularly a kind of X line radiotherapy making mould of suitable shape lead block.
Background technology
Radiotherapy is the important means of treatment malignant tumor patient, tumour occurs and do not control or recur and accept the about 30%-50% of radiocurable patient, its main cause is that the exposure dose of tumour is subjected to the influence of surrounding tissue or organ and can not brings up to the lethal dose of tumour cell.In recent years, 3 D stereo conformal therapy technology is progressively carried out in each hospital, its principle is to utilize computer that the profile in patient's image, tumour and adjacent organs are carried out three-dimensional reconstruction, on 360 ° of circumference that with the tumour are the center, 2-6 irradiation field is set, make shape, the size of every open country consistent with tumor shape, the size of this angle, avoid normal surrounding tissue or organ to greatest extent, the radiotherapy dosage of tumour can further improve like this.General now lead block method or the multi-diaphragm collimator method of adopting of 3 D stereo conformal therapy, promptly the shape that interior shape or multi-diaphragm collimator surrounded of lead is consistent with this angle tumor shape, and the making that therefore keeps off lead becomes the important step that this technology realizes.But domestic existing making mould exists template easily to open, easily fall phenomenon in casting, cause molten plumbous outflow, foam core and suitable shape paper to scrap, particularly the outflow of molten lead causes the volatilization of a large amount of lead steams, fixing not firm to staff's the health other core rod pressing plate that works the mischief, cause core rod and the suitable shape figure dislocation under it during operation easily, had a strong impact on efficient and quality that lead stamp is made.
Summary of the invention
The purpose of this utility model is to provide a kind of suitable shape block casting die of the X line of making the suitable shape lead block of X line that is exclusively used in.
The utility model is achieved in that
The X line is fitted shape block casting die, mainly is made up of base plate and steel casting template, and it is characterized in that: above-mentioned stencil design is four, and four templates surround a vertical casting cavity on base plate, be movably installed with a pressing plate above the casting cavity; On every template, also be provided with a positioning sliding block.
After the utility model adopts said structure, absorption mutually between the casting template, in conjunction with closely, clamp firmly, accurate positioning, there are not cracking, a kind of rhyme scheme in Chinese operas serving as the prelude to a complete score for voices phenomenon, can produce the medical lead block of required form during casting in conjunction with the foam core rod, the lead block reliable in quality that is made is stable, shape, big or small corresponding, avoid the generation of core rod and suitable shape figure inconsistent phenomenon, had effect simple in structure, easy to use, that make efficiency is high, yield rate is high.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
In the accompanying drawing, 1 is that base plate, 2 is that template, 3 is that casting cavity, 4 is that pressing plate, 5 is that positioning sliding block, 6 is that guide groove, 7 is that bayonet lock, 8 is locating hole.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
The utility model is a kind of medical X-ray radiotherapy casting die with suitable shape lead block, mainly is made up of square floor 1, vertically on the base plate 1 is provided with four casting templates 2, and casting template 2 is steel or corresponding material making, generally is designed to 195 * 80 * 20mm.Above-mentioned four templates 2 surround a vertical casting cavity 3 on base plate 1, vertical mutually between adjacent two templates 2, make casting cavity 3 form the cuboid or the square bodily form.The contact end face of every template 2 is provided with magnet, can be adsorbed on the medial surface of adjacent forms 2, guarantees tight connecting between the template 2.Be provided with a T shape guide groove 6 on the upper surface of every template 2 and lateral surface, be installed with a positioning sliding block 5 on this guide groove 6, this positioning sliding block 5 can move forward and backward along guide groove 6; Also be provided with the location on the positioning sliding block 5 with a butterfly screw, be used for fixing between positioning sliding block 5 and the template 2.Also be provided with a bayonet lock 7 on each positioning sliding block 5, be provided with a locating hole 8 that cooperates with bayonet lock 7 at the lateral surface of adjacent forms 2; Behind template 2 location, slip positioning sliding block 5 is installed in the locating hole 8 bayonet lock 7, guarantees to combine closely, fixedly secure between the template 2.Also be provided with casting pressing plate 4 on casting cavity 3, above-mentioned pressing plate 4 is movably arranged in two guide grooves 6 on the template 2; Interfix by screw between pressing plate 4 and the template 2, screw can move forward and backward in the pressing plate groove, and is installed in the guide groove 6 of template 2.
Hand for alleviating template 2 weight and being beneficial to when operating, the lateral surface of every template 2 is provided with arc groove.Also be provided with the base angle on base plate 1 lower surface and adjust screw, to guarantee the horizontal positioned of base plate 1.
Operating process is: the block pallet that will post suitable shape figure is put on the base plate 1, adjusts the base angle screw and makes its level, places template 2 in the periphery of figure, vertically surrounds a square casting cavity 3 between the adjacent forms 2 mutually.Magnet on it is adsorbed on the template 2, effectively reduced between the template 2 in conjunction with the slit.Again positioning sliding block 5 is shifted to corresponding template 2, the bayonet lock 7 on it is inserted in the locating hole 8 of corresponding templates 2, and screws the butterfly screw lock template 2 on it.This moment, every template 2 interfixed, and put into core rod then, pressed core rod pressing plate 4 and fixing by screw, can cast.After molten lead solidifies cooling, unclamp the lead block that pressing plate 4 and template 2 can be taken out required form.
