BACKGROUND

[0002] Iron mould coated sand casting belongs to the category of special casting, and its casting production has the advantages of green, high quality, energy saving, environmental protection and low cost, and is mainly applied to the casting production of large quantities of small and medium castings.

[0003] In recent years, with the rapid development of equipment manufacturing industry, some large equipment puts forward higher requirements for the quality of its castings. The production rate of such castings (such as: main shaft castings, planetary carrier castings and other castings in wind power castings) is not high, and they are large castings (the weight of the castings is more than 10 tons, and the maximum size is 3-6 meters). The casting mold for casting production often needs to be combined by multiple molds.

High-quality castings have become a key bottleneck for improving such equipment. Iron mould coated sand casting gradually applies to the production of these castings due to its unique rapid cooling, high casting rigidity, dense and smooth casting surface and the compensating effect of graphitization expansion during casting iron solidification. The weight of castings produced by iron mould coated sand casting has gradually expanded from several kilograms to several hundred kilograms to several tons to several tens of tons. At the same time, in terms of casting mold separation process in iron mould coated sand casting production, it has also been extended from traditional two-opening mold to three-opening mold, four-opening mold, five-opening mold and other multi-opening mold forms.

The positioning structure 22 of the moving trolley 2 is composed of four positioning pins installed on the working table surface of the trolley body 21 in a cross distribution. When the iron mold 6 and the mold 7 are placed on the working table surface of the moving trolley 2, the positioning pins of the positioning structure 22 are inserted into the corresponding positioning pin holes (see Fig. 6) on the mold base 71 to realize the positioning between the moving trolley 2 and the iron mold 6 and the mold 7. At the same time, the moving trolley 2 can drive the iron mold 6 and the mold 7 to move together when the moving trolley 2 is automatically moving.​​

[0049] As shown in the attached Figure 9 The difference between the structure of the iron mold and the mold of the through type mold stripping separation device and the common iron mold and mold structure is that: in the embodiment, the iron mold bottom surface is provided with a positioning pin hole 62, which is used for positioning the mold 7 and the iron mold 6 during mold closing, and the mutual positioning of the iron mold 6 during mold closing; the upper surface of the iron mold 6 is provided with a positioning pin 61, which is used for the mutual positioning of the iron mold 6 during mold closing; the side surface of the iron mold 6 is provided with four evenly distributed lifting rings 63, which are used for lifting the iron mold 6 away from the mold stripping separation station 5 by the lifting crane 4 after the iron mold 6 and the mold 7 are separated; the mold base 71 is provided with a cross positioning pin hole, when the iron mold 6 and the mold 7 are placed on the moving trolley 2, the cross positioning pin on the moving trolley 2 is inserted into the cross pin hole on the mold base 71, which is used for positioning the mold and the moving trolley 2 and moving the iron mold 6 and the mold 7 together by the moving trolley 2.

[0050] The iron mold and mold stripping separation operation process of the through type mold stripping separation device for multiple different cavity large iron molds in the embodiment is as follows (see the attached Figures 14-21): the lifter beam 12 in the fixed iron mold and mold lifter separation mechanism 1 is lowered to the lowest position under the action of the lifting lifter hydraulic cylinder 16, and the inclined wedge in the inclined wedge clamping mechanism 19 is laterally moved out to the outermost position under the action of the clamping pneumatic device; the moving trolley 2 on one side of the fixed iron mold and mold lifter separation mechanism 1, which is loaded with the iron mold and mold that have completed sand shooting and sand covering molding, automatically drives into the mold separation station 5 for placing the fixed iron mold and mold lifter separation mechanism 1 and then stops; the upper plane of the lifter beam 12 is below the lower plane of the iron mold lifter running edge, and the two planes do not contact each other; the lower plane of the inclined wedge clamping block in the inclined wedge clamping mechanism 19 and the upper plane of the corresponding base clamping plate 72 in the mold base 71 also do not contact each other; the inclined wedge clamping block in the inclined wedge clamping mechanism 19 is inserted laterally to the mold base 71 under the action of the clamping pneumatic device, and when the lower plane of the inclined wedge clamping block in the clamping mechanism 19 and the upper plane of the base clamping plate 72 on the mold base 71 are in complete contact and fit together, the mold and the moving trolley 2 are tightly fixed on the plane of the moving trolley track 3; then the lifting lifter hydraulic cylinder 16 is started to rise, driving the lifter beam 12 to rise, and when the upper plane of the lifter beam 12 contacts the lower plane of the iron mold running edge, the lifting lifter hydraulic cylinder 16 and the lifter beam 12 continue to rise, and under the action of the lifting force of the lifting lifter hydraulic cylinder 16, the iron mold 6 is lifted together, while the mold 7 and the moving trolley 2 are firmly fixed on the moving trolley track 3 and remain stationary under the action of the clamping force of the clamping mechanism 19, and as the lifting lifter hydraulic cylinder 16 continuously lifts the lifter beam 12, the iron mold 6 and the mold 7 gradually separate, and when the lifting lifter hydraulic cylinder 16 and the lifter beam 12 rise to the highest point, the lower plane of the iron mold is higher than the highest point of the mold, and the iron mold 6 and the mold 7 are completely separated; the lifting cable of the lifting crane 4 is tied to the iron mold, the lifting crane 4 completely receives the weight of the iron mold after the lifting crane 4 is lifted, the lifting lifter hydraulic cylinder 16 drives the lifter beam 12 to descend to the lowest position; then the iron mold 6 can be lifted away from the mold separation station 5 by the lifting crane 4 (the iron mold can be moved to the iron mold closing station), and the mold separation between the iron mold 6 and the mold 7 after molding is completed; then the inclined wedge clamping block in the inclined wedge clamping mechanism 19 is laterally moved out to the outermost position under the action of the clamping pneumatic device, and the inclined wedge clamping block and the mold base clamping plate 72 are completely separated, and the clamping mechanism 19 is released from the fixed clamping action with the mold and the moving trolley 2, and the moving trolley 2 carrying the mold can automatically and completely drive away from the iron mold and mold lifter separation station 5, thereby completing the mold separation operation between the iron mold and the corresponding mold; sequentially circulating, the mold separation operation between the iron mold and the mold of different cavity types can be completed.

[0051] The embodiment Figures 16-17 As shown, by withdrawing the chuck to position T1 and clamping the chuck to position T2, it can be seen that the specific positions of the chuck withdrawal and clamping are shown.

[0052] The present embodiment adopts iron type sand coated casting mold to cast large castings. Due to the structure, size, mold removal requirement and other casting process requirements, more than two large iron types are often needed to combine to form the iron type sand coated casting mold required for casting large castings, such as the wind power main shaft casting (see the attached Figures 1-2 ), and the iron type sand coated casting mold forming the outer contour thereof adopts multiple iron types of different shapes and sizes (generally 4 iron types along the length direction of the main wind power main shaft, each iron type having a height of about 1 meter, among which multiple iron types are straight-through type wind power main shaft outer circle casting molds, and one is a connecting flange through type casting mold). As can be seen from the attached Figure 3 , the wind power main shaft iron type sand coated casting mold is formed by coating a layer of sand on the inner cavity of each large iron type, and then stacking the corresponding wind power main shaft outer circle type cavity iron type sand coated casting molds in sequence to form a complete wind power main shaft outer circle contour type cavity iron type sand coated casting mold.

[0053] In the present embodiment, the sand of the large iron type sand coated casting mold is still hot curing phenolic resin coated sand with good fluidity, and the molding of the casting mold cavity of the iron type sand coated layer casting mold adopts the traditional sand shooting and sand coating method, that is, under the action of compressed air, the coated sand is shot into the gap between the mold and the iron type to form a sand coated layer, and under the action of heat, the sand coated layer is solidified, the mold is removed, and finally the iron type sand coated casting mold is formed. When the multiple iron types required for large castings are combined with the mold to complete the sand shooting and sand coating molding, the function of the device of the present embodiment is to sequentially complete the mold removal and separation operation between the multiple iron type casting molds and the mold on the device, so as to obtain complete iron type sand coated casting molds.

[0054] The principle of the through type mold removal device for multiple large iron types of different type cavities in the present embodiment is as follows: the weight of large cast iron castings is generally 10-30 tons, the length in the appearance size of the castings is 4-6 meters, the width size is 2-4 meters, and the height size is 2-4 meters, and the material of the castings is nodular cast iron, gray cast iron, etc. Due to the structure, size and casting process, etc., it is often difficult to form the casting mold required for casting production by using only two iron types. For example, the wind power main shaft casting, the product size of which is generally 4-6 meters in length, 2.8-3.5 meters in diameter of the connecting flange, and 1.5-2.0 meters in diameter of the main shaft neck, belongs to large nodular cast iron castings. The maximum projected diameter of these large iron types is about 5-6 meters, the height is about 1 meter, the weight of each iron type is different, and the weight of the mold is also more than 10 tons. When these castings are produced by using iron type sand coated casting, due to the product structure, size, casting process, etc., 4-5 iron type casting molds are used, and in a large pit, a crane is used to combine the iron types in sequence to form a complete casting mold (see the attached Figure 3), the traditional sand-coated iron mold casting sand-coated sand molding device is often single-station, double-station sand-coated molding machine, that is, each molding machine can complete the sand-coated molding of one iron mold or two different iron molds (lower iron mold) and the mold separation operation of the iron mold and the model. Each sand-coated molding machine includes a set of sand-coated molding device configured with one or two mold separation devices, or two sets of sand-coated molding devices configured with two sets of mold separation devices. After the sand-coated molding of the iron mold is completed, the corresponding mold separation device is used to separate the iron mold casting and the model, and then the iron mold casting is moved out through the iron mold conveying mechanism (usually an iron mold conveying roller) and conveyed to the next process, and the model is fixed in the sand-coated sand station or the mold separation station. If the casting mold of a large casting requires multiple different iron molds, for multiple large iron molds with low efficiency requirements for sand-coated iron mold molding, the above-mentioned traditional iron mold sand-coated molding equipment is not suitable in terms of equipment investment, iron mold casting forming process, iron mold casting logistics operation, and equipment use efficiency. Therefore, a new planning is needed for the sand-coated molding process of multiple different large iron molds.

[0055] The through-type mold separation device for multiple different cavity large iron molds of the present embodiment is a through-type sand-coated molding device for large iron molds. After the sand-coated molding is completed, multiple movable trolleys 2 carrying iron molds and models enter the fixed iron mold and model mold separation mechanism 1 of the present application one by one, and the mold separation operation of each iron mold casting and model is completed one by one through the mold separation operation of each actuator of the device. The separated iron mold and model are moved out of the fixed iron mold and model mold separation mechanism 1 of the present application.

[0056] The mold separation operation efficiency of multiple iron mold castings and models, the logistics direction of the iron mold castings, and the subsequent multiple iron mold casting assembly process requirements of the device can well meet the requirements of large iron mold sand-coated casting production.

[0057] Through the above description, those skilled in the art can implement it.
