Description

Technical Field

[0001] The invention relates to the technical field of mold casting, in particular to a mold steel ejection and demoulding device. Background Art

[0002] Tool steel is a type of steel specifically used to make engineering and plastic processing tools. It usually has high hardness, toughness and wear resistance to adapt to the harsh conditions required for these applications. Tool steel can be divided into many types, such as carbon structural steel, alloy tool steel and high-performance steel. A mold is a tool used to manufacture products. It is usually made of materials such as metal or plastic. It can be used to make products of various shapes and sizes, such as automotive parts, electronic products, toys and furniture. A mold is usually composed of two or more parts, each of which can be moved during the production process to create different shapes. In the injection molding process, the mold is indispensable. The mold is placed in the injection molding machine and pressurized so that it injects the plastic melt into the cavity in the mold. After cooling, the plastic solidifies and is removed from the mold. The mold can be reused after multiple uses as long as they remain intact. The quality of the mold directly affects the quality of the pressure processing process, the precision output of the product and the production cost. In addition to reasonable structural design and processing accuracy, the quality and service life of the mold are mainly affected by the mold material and heat treatment. Mold demoulding refers to the process of separating the finished product from the molding cavity during the manufacturing process.

[0003] At present, after the finished product is produced, it is usually necessary to take out the finished product from the mold, so an ejection demoulding device is required. In order to ensure stability during demoulding, the existing ejection demoulding device usually clamps and fixes the outer side of the mold base. However, during ejection demoulding, the limiting effect of the top of the mold base is poor, and the ejection demoulding will drive the mold base to move as a whole, affecting the ejection demoulding effect of the finished product. In addition, demoulding is usually performed after the product is formed. Preliminary ejection cannot be performed during the casting process of the product, which will cause the molded product to adhere to the inside of the mold. Adhesion may cause scratches, deformation or other defects on the surface of the molded product, affecting the appearance quality, and increasing the difficulty of demoulding, which may lead to an extension of the production cycle and reduce production efficiency. In addition, during strong demoulding, mechanical impact may be caused to the mold, causing deformation or damage to the mold, shortening the service life of the mold. If the adhesion is serious, it may be necessary to stop the machine for cleaning and maintenance, affecting the overall production progress. Summary of the invention

[0004] The object of the present invention is to provide a tool steel ejection and demoulding device to solve the problems raised in the above background technology.

After the product is formed, The support block is driven to move by an electric push rod, which drives the connecting plate and the demolding module to rise, and the product inside the mold base is ejected and demolded, thereby solving the problem that the existing ejection and demolding device usually clamps and fixes the outer side of the mold base to ensure stability during demolding. However, during ejection and demolding, the limiting effect of the top of the mold base is poor, and the ejection and demolding will drive the mold base to move as a whole, affecting the ejection and demolding effect of the finished product. In addition, demolding is usually performed after the product is formed, and preliminary ejection cannot be performed during the casting process of the product, which will cause the formed product to adhere to the inside of the mold, increasing the difficulty of demolding, which may lead to an extension of the production cycle and reduce production efficiency. In addition, during strong demolding, mechanical impact may be caused to the mold, resulting in deformation or damage of the mold, shortening the service life of the mold. If the adhesion is serious, it may be necessary to stop the machine for cleaning and maintenance, affecting the overall production progress. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the clamping plate 5 is slidably connected with a guide rod 24, and the outer side of the guide rod 24 is fixedly connected to the inner wall of the fixed sleeve 10. One end of the guide rod 24 is fixedly connected with a clamping block 25, and the outer side of the clamping block 25 is clamped with the inner wall of the clamping plate 5. The inner wall of the support frame 4 is fixedly connected with a fixing rod 26, and the outer side of the fixing rod 26 is slidably connected to the inner wall of the guide rod 24. The outer side of the fixing rod 26 is provided with a first spring 27. The clamping plate 5 is fixed to the mold base 2 During clamping, the clamping block 25 will contact the mold seat 2, and the support frame 4 will continue to move, which will push the guide rod 24 to slide on the inner wall of the clamping plate 5, so that the guide rod 24 slides on the outside of the fixed rod 26, and the first spring 27 contracts, so that the clamping block 25 is clamped into the inside of the clamping plate 5, and the guide rod 24 pulls the fixed sleeve 10 to move, so that the connecting rod 9 moves, and the connecting rod 9 pulls the limit frame 8 to slide inside the connecting seat 7, so that the limit frame 8 limits the top of the mold seat 2, which is convenient for subsequent ejection and demolding, and avoids the problem of lifting the mold seat 2 during ejection and demolding.

[0030] Two groups of fixing plates 28 are fixedly connected to the outer side of the connecting plate 13, and a mounting rod 29 is fixedly connected to the bottom of the fixing plate 28. The outer side of the mounting rod 29 is slidably connected to the inner wall of the box body 15, and a sliding rod 30 is slidably connected to the inner wall of the box body 15. A protrusion 31 is fixedly connected to the top of the sliding rod 30, and a limiting plate 32 is fixedly connected to the inner wall of the box body 15. A second spring 33 is fixedly connected to the bottom of the inner cavity of the box body 15, and the top of the second spring 33 is fixedly connected to the bottom of the connecting block 17. A mounting frame 34 is fixedly connected to the top of the bottom plate 11, and the inner wall of the mounting frame 34 is slidably connected to the outer side of the mounting rod 29. Pressing the protrusion 31 drives the sliding rod 30 to slide inside the box body 15, and the sliding rod 30 exerts force on the connecting block 17. The pressure drives the connecting frame 16 to rotate, causing the second spring 33 to contract, causing the connecting block 17 on the other side of the connecting frame 16 to rotate upward, driving the mounting rod 29 to move upward, driving the fixing plate 28 and the connecting plate 13 to move upward, and lifting the product inside the mold base 2 through the stripping module 14. The protrusion 31 is released, and the second spring 33 drives the connecting block 17 and the connecting frame 16 to reset. The connecting block 17 is limited by the limiting plate 32. The above process is repeated to avoid the problem of unformed products sticking to the inside of the mold base 2. After the product is formed, the electric push rod 18 is started to drive the support block 19 to move, driving the connecting plate 13 and the stripping module 14 to rise, and the product inside the mold base 2 is ejected and demolded.

[0031] Working principle: When the device is in use, the motor 61 is started to drive the threaded rod 62 to rotate, so that the threaded sleeve 63 moves, the threaded sleeve 63 drives the limit block 64 and the fixed frame 23 to move, the fixed frame 23 drives the support frame 4 to move, so that the slider 22 slides outside the limit rod 21, and the support frame 4 drives the clamping plate 5 to move, so that the two groups of clamping plates 5 clamp and fix the mold seat 2 to improve the stability of the mold seat 2. When the clamping plate 5 clamps the mold seat 2, the clamping block 25 contacts the mold seat 2, and the support frame 4 keeps moving, which will push the guide rod 24 to slide on the inner wall of the clamping plate 5, so that the guide rod 24 slides outside the fixed rod 26. The first spring 27 is moved to contract, so that the card block 25 is stuck in the clamping plate 5, the guide rod 24 pulls the fixed sleeve 10 to move, so that the connecting rod 9 moves, and the connecting rod 9 pulls the limit frame 8 to slide inside the connecting seat 7, so that the limit frame 8 limits the top of the mold seat 2, which is convenient for subsequent ejection and demoulding, and avoids the problem of lifting the mold seat 2 during ejection and demoulding. The pressing block 31 drives the slide bar 30 to slide inside the box body 15, and the slide bar 30 applies pressure to the connecting block 17, driving the connecting frame 16 to rotate, so that the second spring 33 contracts, so that the connecting block 17 on the other side of the connecting frame 16 rotates upward, driving the mounting rod 29 upward. The second spring 33 drives the connecting block 17 and the connecting frame 16 to reset, and the connecting block 17 is limited by the limiting plate 32. The above process is repeated to avoid the problem of unformed products sticking to the inside of the mold base 2. After the product is formed, the support block 19 is driven to move by the electric push rod 18, and the connecting plate 13 and the stripping module 14 are driven to rise, and the product inside the mold base 2 is ejected and demolded, which solves the problem that the existing ejection and demolding device usually moves the mold base 2 to ensure the stability during demolding. The outside is clamped and fixed, but during demolding, the limiting effect of the top of the mold base 2 is poor. Ejection and demolding will drive the mold base 2 to move as a whole, affecting the effect of finished product ejection and demolding. In addition, demolding is usually performed after the product is formed. Preliminary ejection cannot be performed during the casting process of the product, which will cause the formed product to adhere to the inside of the mold, increasing the difficulty of demolding, which may lead to an extension of the production cycle and reduce production efficiency. In addition, during strong demolding, mechanical impact may be caused to the mold, causing deformation or damage to the mold and shortening the service life of the mold. If the adhesion is serious, it may be necessary to stop the machine for cleaning and maintenance, affecting the overall production progress.
