Description

Technical Field

[0001] This utility model relates to the field of die-casting machine crucible technology, specifically to a die-casting machine crucible structure with a replaceable pressure cup. Background Technology

[0002] A die-casting machine crucible is a container used to hold and heat molten metal. It is usually made of refractory material to ensure the smooth progress of the die-casting process. During the melting process of the material in the crucible, additional auxiliary materials (flux, deoxidizer, impurity remover) are usually added. Therefore, the feeding is assisted by a pressure cup connected to the melting chamber.

[0003] In the existing die-casting machine crucibles, the pressure cup is usually cast as a single piece with the crucible, and it is connected to the upper part of the crucible's processing cavity. However, due to long-term use, heating, and continuous feeding, the pressure cup is prone to blockage caused by residual cooled material inside. Since it is cast as a single piece, it cannot be replaced separately, which affects the service life of the crucible and increases the frequency of replacement.

[0004] Therefore, we propose a die-casting machine crucible structure with a replaceable pressure cup to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a replaceable pressure cup crucible structure for a die casting machine. In the process of using existing die casting machine crucibles, the pressure cup is usually integrally cast with the crucible and is connected to the upper part of the processing cavity of the crucible. However, due to long-term use, the pressure cup is heated and continuously fed, which can easily lead to blockage caused by residual cooled material inside. However, because it is integrally cast, it cannot be replaced separately, which affects the service life of the crucible and increases the replacement frequency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-casting machine crucible structure with a replaceable pressure cup, including a crucible body and a guide cone tube obliquely installed at the right end of the crucible body, and a molten material chamber is fixedly installed on the right side of the interior of the crucible body;

[0008] A replacement mechanism is provided above the crucible body, and the replacement mechanism includes a clamping locking ring, and a through slot is provided at the center of the inside of the clamping locking ring.

[0009] Preferably, the cup sleeve body of the cup pressing mechanism is movably installed in the melting cavity opened inside the crucible body, and the cup sleeve body is interconnected with the melting cavity through the feed groove opened at the bottom.

[0010] Preferably, the cup pressing mechanism includes a pressing cup body, which is slidably installed at the center of the cup sleeve body. The connection between the pressing cup body and the cup sleeve body is a conical structure for inlay installation, and the pressing cup body and the cup sleeve body are connected through each other.

[0011] Preferably, the cup pressing mechanism includes a positioning stop ring, which is fixedly installed on the upper outer side of the cup pressing body. The positioning stop ring has an unlocking guide groove at an equal angle on the outer side away from the cup pressing body, and a positioning guide groove at an equal angle on the outer side away from the cup pressing body.

[0012] Preferably, the middle part of the unlocking guide groove and the end of the positioning guide groove in the cup pressing mechanism are connected to each other, and the outer end of the unlocking guide groove passes through the upper and lower sides of the positioning stop ring. The unlocking guide groove and the positioning guide groove are combined to form an inverted "T" shaped structure.

[0013] Preferably, the replacement mechanism includes a locking positioning rod, the top end of which slides through the inside of the clamping locking ring, and the top ends of the locking positioning rods, which are set at equal angles, are all fixedly connected to the bottom surface of the guide rotating disk, and the bottom end of the locking positioning rod is slidably inserted into the inside of the unlocking guide groove and the positioning guide groove.

[0014] Preferably, the replacement mechanism includes a clamping locking ring that is sleeved on the top of the pressure cup body through an internally opened through slot, and a positioning stop ring on the outside of the pressure cup body is attached to the top surface of the clamping locking ring. The replacement mechanism also includes a locking positioning rod for locking the clamping locking ring to the pressure cup body, and the clamping locking ring is fixedly installed above the melting chamber inside the crucible body by bolts.

[0015] Preferably, the replacement mechanism includes a positioning pressure rod, the top end of which is slidably inserted into the bottom end of the live joint sleeve, and the bottom end of the positioning pressure rod can be raised and lowered to abut against the top end of the pressing cup body, so as to realize the input and processing of molten material.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This is a replaceable pressure cup crucible structure for a die-casting machine. The cup sleeve body inside the crucible body is connected to the pressure cup body via a clamping locking ring. Locking and unlocking are completed simply by rotating the locking positioning rod within the unlocking guide groove and the positioning guide groove. This allows for the replacement of the pressure cup body without disassembling other components inside the crucible body. The specific details are as follows:

[0017] 1. The cup sleeve body is installed in the melting chamber, the pressure cup body is inserted into the inside of the cup sleeve body, and then the clamping locking ring is installed on the top of the pressure cup body through the through slot.

At the same time, the bottom end of the positioning pressure rod is inserted into the top of the pressure cup body to complete the overall installation and process the die casting material.

[0018] The die-casting material is fed into the interior of the pressure cup body. The die-casting material moves downward into the interior of the cup sleeve body that is connected through it, and is heated and melted in the melting chamber. After melting, it flows through the feed slot at the bottom of the cup sleeve body into the interior of the guide cone tube so that it can be discharged to the outside for use.

[0019] 2. The bottom end of the locking positioning rod is inserted into the unlocking guide groove opened on the outside of the positioning stop ring. Then, the rotating guide disc drives the locking positioning rod to move towards the positioning guide groove so that the locking positioning rod enters the positioning guide groove to achieve locking.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] Example 1: To solve the problem of replacing the pressure cup in existing die-casting machine crucibles, this example provides a die-casting machine crucible structure with a replaceable pressure cup, comprising a crucible body 1 and a guide cone 2 obliquely installed at the right end of the crucible body 1, and a molten material cavity 3 fixedly installed inside the right side of the crucible body 1; a pressure cup mechanism is provided inside the crucible body 1, and the pressure cup mechanism includes a cup sleeve body 4, and a feed groove hole 5 is opened at the bottom right side of the cup sleeve body 4; the cup sleeve body 4 included in the pressure cup mechanism is movably installed in the molten material cavity 3 opened inside the crucible body 1, and the cup sleeve body 4 is interconnected with the molten material cavity 3 through the feed groove hole 5 opened at the bottom end.

[0032] The cup pressing mechanism includes a pressing cup body 8, which is slidably installed at the center of the cup sleeve body 4. The connection between the pressing cup body 8 and the cup sleeve body 4 is a conical structure for inlay installation, and the pressing cup body 8 and the cup sleeve body 4 are connected through each other.

[0033] A replacement mechanism is provided above the crucible body 1, and the replacement mechanism includes a clamping locking ring 6. A through slot 7 is provided at the center of the inside of the clamping locking ring 6. The clamping locking ring 6 is fixedly installed above the melting chamber 3 inside the crucible body 1 by bolts. The replacement mechanism includes a positioning pressure rod 14, and the top end of the positioning pressure rod 14 is slidably inserted into the bottom end of the live joint sleeve 15. The bottom end of the positioning pressure rod 14 can be raised and lowered to abut against the top end of the pressure cup body 8 so as to realize the input and processing of molten material.

[0034] like Figures 1-3As shown, the cup sleeve body 4 is inserted and installed into the melting cavity 3 inside the crucible body 1. Then, the bottom end of the pressure cup body 8 is inserted into the upper part of the cup sleeve body 4. The connection between the cup sleeve body 4 and the pressure cup body 8 is a conical structure for fitting. Then, the clamping locking ring 6 is sleeved and installed above the positioning stop ring 9 on the outside of the pressure cup body 8 through the through slot 7. The clamping locking ring 6 is locked to the crucible body 1 with bolts. At the same time, the bottom end of the positioning pressure rod 14 is inserted and installed at the top of the pressure cup body 8 to complete the overall installation and process the die casting material.

[0035] Furthermore, by injecting the die-casting material into the interior of the pressure cup body 8, the die-casting material inside the pressure cup body 8 moves downward to the interior of the cup sleeve body 4 that is connected through it, and is heated and melted in the melting chamber 3. After melting, it flows through the feed slot 5 opened at the bottom of the cup sleeve body 4 to the interior of the guide cone tube 2, so as to be discharged to the outside for use.

[0036] Example 2: To solve the problem of replacing the pressure cup of the existing die-casting machine crucible, this example adopts the following technical solution: The pressure cup mechanism includes a positioning stop ring 9, which is fixedly installed on the upper part of the pressure cup body 8. The positioning stop ring 9 has an unlocking guide groove 10 at an equal angle on the side away from the pressure cup body 8, and a positioning guide groove 11 at an equal angle on the side away from the pressure cup body 8. The middle part of the unlocking guide groove 10 and the end of the positioning guide groove 11 are interconnected, and the outer end of the unlocking guide groove 10 passes through the upper and lower sides of the positioning stop ring 9. The unlocking guide groove 10 and the positioning guide groove 11 are combined to form an inverted "T" shaped structure.

[0037] The replacement mechanism includes a locking positioning rod 12, the top end of which slides through the inside of the clamping locking ring 6. The top ends of the locking positioning rods 12, which are set at equal angles, are fixedly connected to the bottom surface of the guide rotating disk 13. The bottom end of the locking positioning rod 12 is slidably inserted into the inside of the unlocking guide groove 10 and the positioning guide groove 11. The clamping locking ring 6 included in the replacement mechanism is sleeved on the top end of the pressing cup body 8 through the through slot 7 opened inside. The positioning stop ring 9 on the outside of the pressing cup body 8 is attached to the top surface of the clamping locking ring 6. The locking positioning rod 12 included in the replacement mechanism is used to lock the clamping locking ring 6 and the pressing cup body 8.

[0038] like Figures 5-7As shown, during the locking and positioning process of the pressing cup body 8, the pressing and locking ring 6 drives the internally slidingly connected guide rotating disk 13 and locking positioning rod 12 to descend synchronously, so as to be sleeved on the outside of the positioning stop ring 9 outside the pressing cup body 8. Then, the bottom end of the locking positioning rod 12 is inserted into the unlocking guide groove 10 opened on the outside of the positioning stop ring 9. Then, the guide rotating disk 13 is manually rotated to drive the locking positioning rod 12 to move towards the positioning guide groove 11, so that the locking positioning rod 12 enters the positioning guide groove 11 to lock, thus preventing the pressing cup body 8 and the positioning stop ring 9 from loosening and falling off during the heating and melting process.

[0039] Furthermore, when it is necessary to replace the pressing cup body 8, the guide rotating disk 13 set on the top surface of the clamping locking ring 6 is manually rotated, so that the guide rotating disk 13 drives the locking positioning rod 12 fixedly connected at the bottom to slide in the positioning guide groove 11. After the locking positioning rod 12 slides into the unlocking guide groove 10, the pressing cup body 8 and the positioning stop ring 9 can be lifted upwards by hand, so that the pressing cup body 8 can be replaced without disassembling other components inside the crucible body 1.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
