DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter die casting machine (100) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative perspective view of the subject matter die casting machine (100) is given. The subject matter invention relates to a die casting machine (100) where casting of wash-basin, shower tray and similar vitrified products are realized and which has at least one first mold (30) and at least one second mold (40) with different heights. Said die casting machine (100) comprises a casting unit (1 ) where casting is realized into said first mold (30) and said second mold (40), and at least one product transfer unit (90) which can provide transfer of the products (94) prepared in said casting unit (1 ).

In Figure 2, a representative perspective view of the casting unit (1 ) in the subject matter die casting machine (100) is given. In the casting unit (1 ), there is a chassis (10) and an upper plate (20) and a lower plate (21 ) associated with said chassis (10). There is a first upper mold (31 ) connected to the face of said upper plate (20) facing the lower plate (21 ) and there is a second lower mold (42) connected to the face of said lower plate (21 ) facing the upper plate (20). For providing movement to the upper plate (20), there is a mold press element (50) associated onto the upper plate (20). In the die casting machine (1 ), there is at least one intermediate plate (22) positioned between the upper plate (20) and the lower plate (21 ) and which can move synchronously with the upper plate (20). A first lower mold (32) is connected to the surface of said intermediate plate (22) facing the upper plate (20) and a second upper mold (41 ) is connected to the surface of said intermediate plate (22) facing the lower plate (21 ).

In Figure 3, a representative frontal view of the casting unit (1 ) in the subject matter die casting machine (100) is given. In the casting unit (1 ), the movement of the upper plate (20) and of the intermediate plate (22) which moves synchronously with the upper plate (20) is provided by means of the mold press element (50). A press plate (51 ) is provided on the surface of the mold press element (50) which contacts the upper plate (20). As seen in Figure 4, said press plate (51 ) has an inclined form and exerts pressure at a point on the upper plate (20). Since the press plate (51 ) exerts pressure at a point, the upper plate (20) can move in an inclined manner with small tolerances with respect to the press point. Thus, the mold (30, 40) faults are eliminated and the product (94) is cast with higher quality.

In the casting unit (1 ), in order to provide synchronous movement of the upper plate (20) and the intermediate plate (22), there are bearing elements (60) on the walls (1 1 ) provided at the chassis (10). Said bearing elements (60) can have shaft (60) form or a similar form. As seen in Figure 6, in the subject matter die casting machine (100), in order to provide precise movement of the upper plate (20) and the intermediate plate (22), at least one channel (12) structure is provided which extends in the orthogonal direction on at least one wall (1 1 ) of the chassis (10). There is at least one first wheel (61 ) which contacts a first edge surface (121 ) of the channel (12) and there is at least one second wheel (62) which contacts a second edge surface (122) of the channel (12) and provided in the same alignment with said channel (12) on the side surfaces (23) of the upper plate (20) and the intermediate plate (22). Thus, the upper plate (20) and the intermediate plate (22) move precisely in a compliant manner to the movement of the press plate (51 ) which has curved form.

At least one angle providing group (80) is provided which is connected onto two mutual walls (1 1 ) in the casting machine. Thanks to said angle providing group (80), the molds (30, 40) can be provided with angles up to 15 degrees and the excessive raw material existing in the mold (30, 40) can be discharged. In the die casting machine (1 ), the assembly apparatus (71 ) seen in Figure 8 is provided in pluralities of numbers and such that there is a predetermined distance in between and it is connected onto the first upper mold (31 ), the first lower mold (32), the second upper mold (41 ) and the second lower mold (42) provided at the first mold (30) and at the second mold (40). There is more than one assembly bearing (70) provided at a predetermined distance such that said assembly apparatus (71 ) can enter and provided on the surfaces of the upper plate (20), the lower plate (21 ) and the intermediate plate (22) whereto the mold is to be connected. The assembly apparatus (71 ) are engaged to said mold assembly bearings (70), the first upper mold (31 ), the second upper mold (41 ) and the first lower mold (32) and the second lower mold (42) are connected onto the lower plate (21 ) and the intermediate plate (22). Thus, the molds (30, 40) which can have different dimensions can be assembled to and disassembled from the upper plate (20), the lower plate (21 ) and the intermediate plate (22) in a rapid and safe manner.

In the die casting machine (100), the first upper mold (31 ) and the second upper mold (41 ) are opened by means of the mold press element (50) associated with the upper plate (20) in the casting unit (1 ), and the product (94) whose casting process is completed is reached. For providing transfer of the product (94) which has completed the casting process, at least one product transfer unit (90) is positioned in front of the die casting machine (100). As seen in Figure 10, in the product transfer unit (90), there is a carrier plate (921 ) in order to provide transfer of product (94) which exits the second mold (40) and the first mold (30) opened by means of the mold press element (50). There is an orthogonal movement mechanism (93) which provides upward and downward movement linearly in a direction Y (II) for providing positioning of said carrier plate (921 ) to the alignment of the first mold (30) or the second mold (40). In order to provide forward and backward movement of the carrier plate (921 ) linearly in a direction X (I), there is at least one horizontal movement mechanism (91 ).

In Figure 1 1 , a representative lateral view where the movable carrier (920) has advanced in direction which is reverse to the direction X (I) in the product transfer unit (90) in the subject matter die casting machine (100) is given. In the die casting machine (100), the carrier plate (921 ) arrives at the alignment of the related mold (30, 40) by means of the orthogonal movement mechanism (93) in order to provide transfer of the product (94), of which the casting process is completed, from the first mold (30) and from the second mold (40) positioned one above the other in the die casting machine (100). In order to provide upwardly and downwardly movement of the carrier plate (921 ) in direction Y (II), there is at least one truss foot (931 ) structure in the orthogonal movement mechanism (93). Thanks to the truss foot (931 ), the carrier plate (921 ) is moved forwardly and backwardly in direction Y (II). In the horizontal movement mechanism (91 ) provided in the product transfer unit (90), there is a movable carrier (920) comprising the carrier plate (921 ) and a lower plate (922) provided under the carrier plate (921 ). Said movable carrier (920) can move forwardly and backwardly in direction X (I) by being moved by a drive element (923). There is at least one fixed carrier (910) positioned in the same plane with the movable carrier (920) and where the movable carrier (920) is rested end to end as a result of the movement of the movable carrier (920) in the direction which is opposite to the direction X (I). There is more than one carrying element (924) positioned on the carrier plate (921 ) and which rotates in its own axis for facilitating movement of products (94) in the direction which is opposite to said direction X (I). By means of the carrying elements (924), the products (94) are transferred from the movable carrier (920) to the fixed carrier (910). In order to provide advancing of products (94), transferred from the movable carrier (920), by means of continuing the movement of said products (94) in direction which is opposite to direction X (I), there is a transfer surface (91 1 ) having pluralities of carrying elements (924) which rotate in their own axis and provided on said fixed carrier (910). Thanks to said transfer surface (91 1 ), the products (94) existing on the fixed carrier (910) can be transferred when desired without needing to carry manually.

In the horizontal movement mechanism (91 ), there is an opening (912) provided under the transfer surface (91 1 ) in the fixed carrier (910) and which has a width such that the extension of the lower plate (922) provided under the carrier plate (921 ) enters. The lower plate (922) enters into and exits said opening (912) during the forward backward movement of the movable carrier (920) in direction X (I), and the carrier plate (921 ) is rested to the transfer surface (91 1 ). As the carrier plate (921 ) is rested to the transfer surface (91 1 ), product (94) can be transferred from the movable carrier (920) onto the fixed carrier (910). Thus, in the die casting machine (100) having the first mold (30) and the second mold (40) with different heights, transfer of the products (94) whose casting process is completed is provided.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
