Description

Technical Field

[0001] The invention relates to the technical field of die-casting technology, in particular to a die-casting die with a function of removing a slug in a die. Background Art

[0002] Die casting mold is a special tool used to manufacture metal parts, usually used in high-pressure casting process. Die casting mold is designed to quickly inject liquid or semi-liquid metal into the mold cavity under high pressure, and cool and solidify in a short time to form metal parts of the desired shape.

[0003] In die-casting molds, cleaning the sprue (usually the gate part) is an important maintenance task to ensure the continuous and efficient operation of the mold. In the existing technology, some of them clean the sprue by mechanical cutting, or workers use files, grinding wheels or other tools to remove the sprue; such methods require an additional process to clean the sprue, which undoubtedly makes the die-casting work more complicated and reduces the efficiency of the die-casting work. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a die-casting mold with a function of removing the slug in the mold in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: to provide a die-casting mold with a function of removing the slug in the mold, comprising: A fixed die assembly, on which a feed sleeve is arranged; A movable plate, which is movably arranged on the fixed mold assembly and has a pressing position and a separation position thereon, wherein the movable plate can be in the pressing position when the die-casting mold is in a closed state, and in the separation position when the die-casting mold is in an open state; A movable mold assembly, which is movably abutted against the movable plate to form a product cavity; A material channel is arranged in the movable plate, one end of the material channel is connected to the feed sleeve, and the other end is connected to the product cavity, the center line of the material channel and the center line of the feed sleeve are not in a straight line, and the material channel can be separated from the feed sleeve when the movable plate is switched from the abutting position to the separation position; A material head is formed in the feed sleeve, and a material handle is formed in the material channel. The material head and the material handle are formed integrally. The material head can be switched from the abutting position to the separation position due to the movable plate, and can be separated from the feed sleeve and rotated relative to the material handle, so as to disconnect the material handle.

[0006] In the above-mentioned die-casting mold with the function of removing the slug in the mold, the inner side wall of the feed sleeve is inclinedly provided with a plurality of inclined grooves, and the inclined grooves are used to form inclined tops in the circumferential direction of the slug. The inclined top can move along the inclined grooves due to the movable plate switching from the abutting position to the separation position, so as to rotate the slug relative to the material handle.

[0007] In the above-mentioned die-casting mold with the function of removing the material head in the mold, the diameter of one end of the material channel connected to the feed sleeve gradually decreases at a position close to the feed sleeve.

[0008] In the above-mentioned die-casting mold with the function of removing the slug in the mold, a connecting column is arranged on the fixed mold assembly, and the movable plate is movably sleeved on the connecting column.

[0009] In the above-mentioned die-casting mold with the function of removing the slug in the mold, an abutment portion is provided at one end of the connecting column away from the fixed mold assembly. The abutment portion can abut against the movable plate when the movable plate is switched from the abutting position to the separated position, so as to prevent the movable plate from being separated from the connection with the fixed mold assembly.

[0010] In the above-mentioned die-casting mold with the function of removing the slug in the mold, a guide column is arranged on the movable plate, a guide hole is arranged on the movable mold assembly, and the guide column is movably inserted in the guide hole to provide guidance for the movement of the movable mold assembly.

[0011] Compared with the prior art, the advantage of the present invention is that, by arranging a movable plate on the fixed mold assembly, when the mold is opened, the movable plate is converted from the pressing position to the separation position on the fixed mold assembly, thereby driving the material channel to separate from the feed sleeve, and the material head is driven by the material handle in the material channel to separate from the feed sleeve and rotate relative to the material handle. Since the center lines of the feed sleeve and the material channel are not on the same straight line, the rotation of the material head can disconnect the connection between it and the material handle, thereby realizing effective separation of the material head and the material handle. At this time, the material head has been completely separated from the product and can be easily taken out between the fixed mold assembly and the movable plate. The material head can be cleaned while the mold is opened. Since the material head and the material handle have been disconnected, the material head can be directly removed without adding an additional process to clean the material head. Through the automated separation and cleaning process, the time and cost of manual intervention are reduced, and the production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figures 1 to 5 As shown, a die-casting mold with a function of removing a material head in a mold of the present invention comprises: a fixed mold component 1, on which a feed sleeve 2 is arranged; a movable plate 3, which is movably arranged on the fixed mold component 1 and has a pressing position and a separation position thereon, and the movable plate 3 can be in the pressing position when the die-casting mold is in a mold closing state, and can be in the separation position when the die-casting mold is in a mold opening state; a movable mold component 4, which is movably pressed against the movable plate 3 to form a product cavity; a material channel, which is arranged in the movable plate 3, one end of the material channel is connected with the feed sleeve 2, and the other end is connected with the product cavity, the center line of the material channel is not in a straight line with the center line of the feed sleeve 2, and the material channel can be separated from the feed sleeve 2 when the movable plate 3 is switched from the pressing position to the separation position; a material head 5 is formed in the feed sleeve 2, and a material handle 6 is formed in the material channel, and the material head 5 and the material handle 6 are integrally formed, and the material head 5 can be switched from the pressing position to the separation position due to the movable plate 3, and rotate relative to the material handle 6 when separated from the feed sleeve 2, so as to disconnect the connection with the material handle 6.

[0016] The working steps of the die-casting mold in this scheme are as follows: first, the die-casting mold is closed. At this time, the movable mold component 4 is against the movable plate 3, and the movable plate 3 is pressed against the fixed mold component 1. This process ensures that the various parts of the mold are tightly fitted, providing a closed cavity space for the subsequent injection of the molten metal. Subsequently, the molten metal flows into the material channel from the feed sleeve 2, and flows into the product cavity from the material channel, filling the product cavity to form the desired product shape. After the product is formed, the molten metal is rapidly cooled and solidified in the mold cavity to form the final product. At this time, the molten metal has been completely solidified and is connected to the material head 5 and the material handle 6. After the product is formed, the die-casting mold is opened. At this time, the movable mold component 4 drives the product in the cavity to separate from the fixed mold component 1, and the movable plate 3 is driven to move relative to the fixed mold component 1 under the action of the binding force between it and the product. , switched from the tight position to the separation position, the material channel is separated from the feed sleeve 2 under the drive of the movable plate 3, and at the same time, the material head 5 is separated from the feed sleeve 2 and rotated relative to the material handle 6 under the drive of the material handle 6 in the material channel. Since the center lines of the feed sleeve 2 and the material channel are not on the same straight line, an eccentric structure is formed, and the rotation of the material head 5 can disconnect the connection between it and the material handle 6, thereby realizing the effective separation of the material head 5 and the material handle 6. At this time, the material head 5 has been completely separated from the product and can be easily taken out between the fixed mold assembly 1 and the movable plate 3. The material head 5 can be cleaned while the mold is opened. Since the material head 5 and the material handle 6 are disconnected, the material head 5 can be directly removed without adding an additional process to clean the material head 5. Through the automated separation and cleaning process, the time and cost of manual intervention are reduced, and the production efficiency is improved.

[0017] Furthermore, the inner side wall of the feed sleeve 2 is obliquely provided with a plurality of inclined grooves 7, which are used to form inclined tops 8 in the circumferential direction of the material head 5; when the mold in this scheme is opened, the movable mold assembly 4 drives the product in the cavity to separate from the fixed mold assembly 1, and due to the bonding force between the product and the movable plate 3, the movable plate 3 is driven to switch from the tight position to the separation position, thereby driving the material channel to separate from the feed sleeve 2, and the material handle 6 in the material channel drives the material head 5 integrally formed with it to move away from the feed sleeve 2. Due to the angle design of the inclined groove 7, the inclined top 8 will force the material head 5 to rotate around the axis of the material handle 6, and the center lines of the material head 5 and the material handle 6 are not on the same straight line, forming an eccentric structure. Therefore, during the rotation of the material head 5 relative to the material handle 6, the connection between the two is easier to disconnect.

[0018] Furthermore, the diameter of one end of the material channel connected to the feed sleeve 2 gradually decreases near the feed sleeve 2. The purpose of this design is to create a weakest area, namely the connection between the material head 5 and the material handle 6. Such a tapered design forms a point that is easy to break between the material head 5 and the material handle 6. By making the connection between the material head 5 and the material handle 6 the most fragile part of the entire structure, when the material head 5 rotates due to the action of the inclined top 8 during the mold opening process, the material handle 6 will not be driven by the material head 5 to rotate together. This is because the stress concentration at the weakest point causes the material head 5 to break first, rather than rotating as a whole. This avoids the possibility of the material handle 6 rotating with the material head 5, thereby simplifying the processing work after demolding, reducing the post-processing steps, and improving production efficiency.

[0019] In order to ensure a reliable connection between the movable plate 3 and the fixed mold assembly 1, a connecting column 9 is provided on the fixed mold assembly 1, and the movable plate 3 is movably mounted on the connecting column 9. This design allows the movable plate 3 to move smoothly during the mold closing and mold opening processes. Specifically, the connecting column 9 not only provides a physical connection between the movable plate 3 and the fixed mold assembly 1, but also plays a guiding and limiting role, thereby ensuring the stability and accuracy of the movable plate 3 during movement.

[0020] Furthermore, an abutment portion 10 is provided at one end of the connecting column 9 away from the fixed mold assembly 1. When the mold in this scheme is opened, the movable mold assembly 4 drives the product in the cavity away from the fixed mold assembly 1. Due to the binding force between the product and the movable plate 3, the movable plate 3 is driven to switch from the abutment position to the separation position. At this time, the abutment portion 10 contacts and provides support for the movable plate 3. Subsequently, the product continues to be driven by the movable mold assembly 4 to separate from the movable plate 3. This design ensures the stability and reliability of the movable plate 3 during the entire mold operation process.

[0021] Furthermore, a guide column 11 is provided on the movable plate 3, and a guide hole 12 is provided on the movable mold assembly 4. The guide column 11 is movably inserted in the guide hole 12 to provide guidance for the movement of the movable mold assembly 4. Specifically, the guide column 11 is designed to ensure the accurate alignment and stable operation of the movable mold assembly 4 during the mold opening and closing processes; when the mold is closed, the movable mold assembly 4 approaches the movable plate 3, and the guide column 11 on the movable plate 3 will be accurately inserted into the guide hole 12 on the movable mold assembly 4. The cooperation between the guide column 11 and the guide hole 12 not only provides precise guidance for the movable mold assembly 4, but also ensures the accurate alignment between the movable mold assembly 4 and the fixed mold assembly 1.
