Problems solved by technology

[0004] Aiming at the problem in the prior art that the weak part of the cantilever connection of the 3D printing sand core is easy to break due to stress concentration during hoisting, the invention provides a semi-cantilever structure sand core lifting tool, which can be lifted by changing the sand core product. The stress-bearing part during transportation, so as to avoid the weak part connected by the cantilever wall of the sand core from breaking due to stress concentration during transportation

Embodiment 1

[0019] Such as figure 2 Shown is the hanger for the sand core of the semi-cantilever structure of the present invention, comprising a rectangular frame connected by section steel, which is vertically arranged, and the rectangular frame includes an upper beam 1, a lower beam 2 and connecting the upper beam 1 and The two columns 3 of the lower beam 2, the upper beam 1 is horizontally connected with two upper beams 4, the lower beam 2 is horizontally connected with two lower beams 5, and the upper beam 4 and the lower beam 5 are located on the same side of the rectangular frame. On the side, the lifting beam 6 is also connected between the upper support beams 4, and the upper side of the lifting beam 6 is provided with lifting lugs 7. In order to facilitate the installation and connection of the parts of the spreader and ensure the connection strength and rigidity, the upper beam, lower beam, column, upper support beam, lower support beam, lifting beam and pull rod in the spread...

Embodiment 2

[0023] Take the example image 3 Take the sand core structure as an example, describe in detail the method for lifting the sand core with a hanger for the semi-cantilever structure sand core of the above-mentioned embodiment 1, image 3 The sand core product shown is a 3D printed sand core for an internal combustion engine body. In this sand core structure, the weight of the main body of the sand core is located in the core part inside the sand core. The core part and the external core structure are in a semi-hanging state. In the prior art, during the lifting process of the sand core assembly, the lifting handle is used to hang the outer side of the sand core. After the sand core is lifted, the internal molding sand is prone to stress concentration due to the action of gravity And break, causing damage to the sand core. When the sand core is hoisted with the spreader in Example 1, the occurrence of the above-mentioned damage problem is completely avoided. The specific proces...

Abstract

The invention relates to the technical field of assisting devices of 3D printing sand core products, and relates to a lifting appliance for a semi-suspension wall structure sand core and a lifting method thereof. The lifting appliance for the semi-suspension wall structure sand core comprises a rectangular framework, wherein the rectangular framework is formed by connecting structural steels, therectangular framework is arranged vertically and comprises an upper cross beam, a lower cross beam and two stand columns, the two stand columns are used for connecting the upper cross beam with the lower cross beam, the upper cross beam is horizontally connected with two upper support beams, the lower cross beam is horizontally connected with two lower support beams, the upper support beams and the lower support beams are located at the same side of the rectangular framework, a lifting beam is further connected between the upper support beams, and lifting lugs are arranged on the upper side ofthe lifting beam. According to the lifting appliance structure, the rectangular framework formed by connecting the structural steels is connected with the upper support beams and the lower support beams to form a C-shaped structure with a lateral opening, the C-shaped structure is used for matching with a main body part of the lifting sand core, the direct lifting mode during lifting of a productis changed, so that the problem that the suspension wall part is broken due to stress concentration during the lifting of the semi-suspension wall structure sand core is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of laying aids for 3D printing sand core products, in particular to a lifting tool for sand cores with a semi-cantilever structure and a lifting method thereof. Background technique [0002] In view of the superiority of 3D printing technology, it has become more and more common in casting in recent years. It is used in complex castings such as cylinder heads, large machine tool parts and internal combustion engine bodies. In sand casting, 3D printing sand cores and sand molds replace traditional casting molds, which can be integrated without mold removal and material removal, and even the whole core casting method is proposed, which greatly simplifies the operation process and improves production efficiency. However, 3D printing also has its unique shortcomings. For example, the inside of the sand core cannot be printed together with the mandrel, which makes the connection strength between the connection p...
