Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting moulds, in particular to a casting mold from which castings can be automatically separated. Background Art
[0002] Demolding is an important step in metal casting. There are many casting methods, so the process is also different. Simply put, it generally goes through model making - injecting molten metal into the model - condensation of molten metal, molding - demolding - casting processing (including grinding, heat treatment, chemical treatment, etc.), and the demolding process is to make the casting better removed from the model and improve casting efficiency and quality.
[0003] At present, the demoulding method of castings is still mostly manual demoulding. The manual demoulding method is generally suitable for composite products with simpler shapes, and its adhesion and adsorption forces are relatively small. Usually, the mold is hit with a wooden hammer or a rubber hammer first. During the hitting process, the mold itself may be damaged to a certain extent. At the same time, the knocking vibration may cause the composite material inside the mold to rupture. When demoulding a mold that is too large, it cannot be separated by knocking and vibration alone. The main method of mechanical demoulding relies on flipping the mold and vibrating the mold to separate the mold from the composite material. However, the surface of the mold cavity is rough. If there are gouges, marks, and other surface defects in the mold cavity and runner, the plastic part is easy to adhere to the mold, resulting in difficulty in demoulding. Over time, the mold will be damaged, causing the casting accuracy error to be too large. Utility Model Content

[0026] like Figure 1 and Figure 3 As shown, the automatic demoulding mechanism includes a first slide 6, a mold 7, a movable bottom plate 14 and a first baffle 13. The first baffle 13 is arranged on the upper end surface of the main body 1. The first slide 6 is opened at the central position of the inner wall of the first baffle 13, and the scraper 5 can slide left and right along the first slide 6. The movable bottom plate 14 is arranged at the output end of the hydraulic ejector 9. The mold 7 is arranged at the upper end of the movable bottom plate 14, and the movable bottom plate 14 can move back and forth repeatedly inside the mold 7. A cooling mechanism that can quickly cool down the mold 7 is arranged on the outer side of the first baffle 13. The article inside the mold 7 has been changed into a finished product after the plasticity of the mold 7. The mold 7 separates the finished product inside the mold 7 from the mold through the movable bottom plate 14 at the bottom. 7, the movable bottom plate 14 moves upward under the drive of the hydraulic push rod 9, and the finished product inside the mold 7 is separated from the inside of the mold 7 by the movement of the movable bottom plate 14. At the same time, the movable bottom plate 14 is lifted to the highest point flush with the top surface of the mold 7 under the drive of the hydraulic push rod 9. At the same time, the scraper 5 moves along the first slide groove 7 opened in the first baffle 13 under the drive of the push rod 4. Under the drive of the push rod 4, the scraper 5 pushes the finished product lifted by the movable bottom plate 14 forward through the first slide groove 6, so that the cast product is completely separated from the mold 7.

The coolant spraying rods 12 spray out the coolant for rapid cooling of the mold 7. The second baffle 19 can control the reciprocating motion of the scraper 5. The push rod 4 is driven by the electric push rod 3. The push rod 4 penetrates the second baffle 19 to drive the scraper 5. The push rod 4 drives the scraper 5 during the reciprocating movement of the electric push rod 3. The scraper 5 moves to the surface of the second baffle 19 during the movement process because the second baffle 19 is fixedly connected to the first baffle 13 and does not move. Therefore, the second baffle 1 9 can control the moving position of the scraper 5 so that it cannot be separated from the main body. The surface of the coolant spraying rod 12 is provided with a plurality of nozzles for spraying the coolant in the coolant spraying rod 12. After the coolant is sprayed out by the coolant spraying rod 12, the coolant is quickly discharged by a plurality of fans 15 fixed on the surface of the first baffle 13 when it is discharged from the inside of the main body 1. At the same time, the coolant spraying rod 12 and the fan 15 form a reflux inside the main body 1 to accelerate the circulation of air on the surface of the mold 7. The coolant spraying rod 12 and the fan 15 quickly cool down the mold 7, and cooperate with the automatic demoulding mechanism to achieve automatic casting demoulding.

A synchronization rod 17 is provided on one side of the fixing buckle 10, and one side of the synchronization rod 17 is fixedly connected to the fixing buckle 10, and the other side is fixedly connected to the hydraulic push rod 9. A groove is provided on the outer surface of the fixing buckle 10, and mold fixing buckles 18 are provided at both ends of the outer surfaces of the two groups of fixing buckles 10. The outer walls of molds 7 of different models can be placed in the grooves of the fixing buckles 10, and the mold fixing buckles 18 are used to connect the mold 7 to the fixing buckle 10.
[0029] like Figure 1-3As shown, a casting mold main body 1 from which a casting can be automatically detached has two sets of slide bars 11 fixedly and symmetrically arranged inside, and the slide bars 11 are connected to the fixed buckles 10 for sliding left and right movement, a second slide groove 16 is provided on the other side of the hydraulic ejector 9 away from the movable bottom plate 14, a material receiving rack 8 is fixedly arranged on the outer side of the front end of the main body 1, the second slide groove 16 is connected to the hydraulic ejector 9 for sliding left and right movement, a movable bottom plate 14 is slidingly arranged at the bottom of the mold 7, and a hydraulic ejector 9 fixedly connected to the movable bottom plate 14 is arranged on one side of the movable bottom plate 14, and the movable bottom plate 14 moves back and forth inside the mold 7 under the push of the hydraulic ejector 9, so as to move the composite material in the mold 7 to the mold 7. The object is pushed out, and the fixed buckle 10 reciprocates along the sliding rod 11. At the same time, one side of the fixed buckle is connected through the synchronous rod 17. One side of the synchronous rod 17 is connected to the fixed buckle 10, and the other side is connected to the hydraulic push rod 9. When the fixed buckle 10 reciprocates through the sliding rod 11, it drives the synchronous rod 17, and the synchronous rod 17 is connected to the hydraulic push rod 9. The synchronous rod 17 drives the hydraulic push rod 9 to reciprocate. The second slide 16 is connected to the hydraulic push rod 9 for sliding left and right, so that the hydraulic push rod 9 reciprocates within a certain range in the second slide 16. The coolant spray rod 12 makes it cool down quickly and cooperates with the movable bottom plate 14 and the scraper 5 to separate the objects or parts and then drop them into the receiving rack 8.
[0030] Working principle: A casting mold with automatic detachable castings. The compound to be molded is heated into a fluid and then introduced into the mold 7 inside the main body 1. Two sets of slide bars 11 are installed inside the main body 1. The two sets of slide bars 11 are slidably installed with fixing buckles 10. The mold 7 is buckled in the slide groove of the fixing buckle 10 through the mold fixing buckle 18. At the same time, several sets of coolant spraying rods 12 are installed inside the main body 1. When the slide bar 11 drives the mold 7 through the fixing buckle 10, the synchronous rod 17 drives the hydraulic ejector 9 to reciprocate in the second slide groove 16. At the same time, the mold 7 is also driven by the synchronous rod 17. A first baffle 13 is fixedly provided on the upper surface of the main body 1. Several sets of fans 15 are fixedly installed on one side surface of the first baffle 13. The fans 15 and several sets of coolant spraying rods 12 inside the main body 1 form a reciprocating mechanism. The coolant is transported to the coolant spray rod 12 through the pipeline, and sprayed out through the coolant spray rod 12 to accelerate the rapid cooling of the compound inside the mold 7. At the same time, the electric push rod 3 on the upper outer side of the main body 1 drives the push rod 4 to drive the scraper 5 to reciprocate along the first slide groove 6 inside the first baffle 13. During the movement, the second baffle 19 can prevent the push rod 4 from moving too far and damaging the mold 7. When the mold 7 moves through the slide rod 11 and the fixed buckle 10, the hydraulic push rod 9 driven by the synchronization rod 17 lifts the movable bottom plate 14 at the bottom of the mold 7 to push the compound inside the mold 7 out of the mold 7. At the same time, the scraper 5, in cooperation with the electric push rod 3 and the push rod 4, pushes the hydraulic push rod 9 and the sliding bottom plate out of the mold 7. The compound is pushed by the scraper 5 to the receiving rack 8 to complete the automatic demolding of the casting.
