Description
Technical Field
The utility model relates to a roll child foundry goods psammitolite core bone.
Background
Most of the roller tire sand cores are cylindrical, the conventional sand core ribs are manufactured by welding round steel or steel pipes, the integral structure of the conventional sand core ribs is prone to serious deformation after repeated use, and the welding spots are prone to cracking and desoldering, so that the lifting safety of the sand core is seriously affected. In addition, the roller tire sand core manufactured by using the conventional sand core frame is completely compact and integral, so that the exhaust of the sand core during casting is not facilitated, and the sand consumption for molding is excessive.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a roll child foundry goods psammitolite core bone to solve prior art well psammitolite core bone fracture and desolder easily, and the great problem of molding sand consumption.
The core rod of the sand core of the roller tire casting comprises a bone cylinder, a supporting device and round steel, wherein the supporting device comprises reinforcing ribs and an apron plate, the apron plate is fixedly connected with the bottom of the bone cylinder, the apron plate is evenly distributed along the circumferential direction of the bone cylinder, the reinforcing ribs are fixedly connected between the apron plate and the bone cylinder, the bottom of the round steel transversely penetrates through the bone cylinder, and the top of the round steel is higher than the top of the bone cylinder.
Preferably, the round steel includes ear of hanging and insertion portion, ear of hanging is the type of falling U structure, insertion portion has two L type pipes to constitute, two the top of L type pipe with ear of hanging portion fixed connection, two the bottom of L type pipe transversely runs through the bone section of thick bamboo.
Preferably, the round steel is evenly arranged along the circumferential direction of the bone cylinder.
Preferably, the reinforcing ribs are uniformly distributed on the apron board along the circumferential direction of the bone drum.
Preferably, the skirt plate is of a fan-shaped structure and is perpendicular to the bone cylinder.
The utility model has the advantages that: the device can pass through the skirtboard, the setting of the extension of strengthening rib and round steel, make the device can provide certain holding power to the psammitolite at the handling in-process, lift by crane security greatly increased, the device can also pass through the tubular structure of bone section of thick bamboo, the holistic structural strength of core bone has been increased, reuse number of times has been improved, and the cracked safety problem of lug position desoldering can not appear, and the tubular structure can improve the inside exhaust problem of psammitolite effectively, when reducing the risk of foundry goods surface gas defect, the quantity of molding sand also significantly reduces, to a great extent has reduced the comprehensive cost.

Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.
As shown in fig. 1-3, the utility model provides a roller casting psammitolite core bone, including bone section of thick bamboo 1, strutting arrangement and round steel 2, strutting arrangement includes strengthening rib 3 and skirtboard 4, skirtboard 4 and bone section of thick bamboo 1's bottom fixed connection, and skirtboard 4 evenly arranges along 1 circumference of bone section of thick bamboo, fixedly connected with strengthening rib 3 between skirtboard 4 and the bone section of thick bamboo 1, and bone section of thick bamboo 1 is transversely run through to the bottom of round steel 2, and the top of round steel 2 is higher than the top of bone section of thick bamboo 1.
The round steel 2 is evenly distributed along the circumference of the bone tube 1.
The reinforcing ribs 3 are uniformly distributed on the skirt board 4 along the circumferential direction of the bone barrel 1.
The skirt board 4 is of a fan-shaped structure and is perpendicular to the bone barrel 1.
When casting work is required, firstly, a part of sand is placed in a sand mold cavity, then the device is placed, sand is continuously injected into the sand mold cavity until the sand mold cavity is filled, a groove is dug from the top after tamping, the lifting lug part of the round steel 2 in the groove is required to be exposed, so as to complete the subsequent hoisting work, the apron board 4, the reinforcing ribs 3 and the extending parts of the round steel 2 can provide certain supporting force for the sand core in the hoisting process, the hoisting safety is greatly increased, the device can also increase the integral structural strength of the core bar and improve the reuse times through the cylindrical structure of the bone tube 1, and the cracked safety problem of lug position desoldering can not appear to tubular structure can improve the inside exhaust problem of psammitolite effectively, when reducing the risk of foundry goods surface gas defect, the quantity of molding sand also significantly reduces, and to a great extent has reduced the comprehensive cost.
The present invention has been described in detail with reference to the accompanying drawings, and it is apparent that the present invention is not limited by the above embodiments, and various insubstantial modifications of the inventive concept and technical solutions of the present invention or direct application of the inventive concept and technical solutions to other applications without modification are within the scope of the present invention.
