Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold that uses one slide to drive the movement of multiple different slides. Background Technology

[0002] Molds refer to various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded.

[0003] Injection molds are the molds used in injection molding processes. Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and shapes, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0004] Generally, a single slide seat can only drive slide inserts at two or three angles. Requires two or more slide seats, making the structural processing more complex, resulting in longer mold design time and processing cycles, leading to increased design costs. More slide seats also require more time for mold fitting, maintenance, and upkeep, further extending the production cycle, reducing production efficiency, and causing defects and other issues. Therefore, this does not meet current needs. To address this, we propose an injection mold that uses one slide to drive the movement of multiple different slides. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold that uses one slide to drive multiple different slides, in order to solve the problems mentioned in the background art, which generally only drive two or three slide inserts at different angles through one slide seat, requiring two or more slide seats, making the structure and processing more complex, resulting in longer mold design time and processing cycle, leading to higher design costs, and requiring more time for mold matching, maintenance and upkeep when there are more slide seats, thus leading to longer production cycle, reduced production efficiency, defective products and other factors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold using one slide to drive multiple different slide movements, including a moving mold plate and a fixed mold plate. The moving mold plate and the fixed mold plate are connected by mold guide pillars and guide sleeves. The bottom of the moving mold plate is inlaid with multiple inclined guide pillars. The upper surface of the fixed mold plate is detachably mounted with a core. The surface of the core is provided with an injection cavity. Two symmetrically distributed slide blocks are slidably mounted on both sides of the core. A connecting slider is installed between two adjacent slide blocks at their ends. The connecting slider drives the slide blocks to slide on the surface of the core. Multiple slide inserts are slidably engaged on the side of the slide blocks facing the injection cavity. The slide inserts slide in contact with the core and one end extends into the inside of the injection cavity.

[0007] Preferably, the surface of the sliding block is provided with a plurality of oblique guide post holes, and the oblique guide post holes are vertically aligned with the oblique guide post positions.

[0008] Preferably, multiple insert sliding grooves are provided on both sides of the injection molding cavity, and the sliding insert is slidably installed inside the insert sliding groove.

[0009] Preferably, a sliding insert pressure plate is provided above the insert sliding groove, and the sliding insert pressure plate is connected to the core by screws.

[0010] Preferably, the side of the sliding block that connects to the sliding insert is provided with a sliding guide groove, and the bottom of the end of the sliding insert that connects to the sliding block is provided with a sliding snap groove.

[0011] Preferably, the sliding engagement groove at the bottom of the end of the sliding insert is engaged with the edge of the sliding guide groove, and the end of the sliding engagement groove is engaged with the inside of the sliding guide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a sliding block to drive the sliding insert to move linearly along the length of the sliding insert, thereby enabling multiple sliding inserts to move simultaneously. The movement distance of the sliding block is limited by the limiting ball screw. This eliminates the need to install multiple sliding blocks, simplifies mold components, optimizes mold design and manufacturing costs, reduces mold component maintenance costs, and ensures product production stability. It also significantly shortens the product injection molding cycle, reduces product defect rate, and improves overall product quality and production stability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, an injection mold that uses one slide to drive multiple different slides includes a moving platen 1 and a fixed platen 2. The moving platen 1 and the fixed platen 2 are connected by mold guide pillars and guide sleeves. Multiple inclined guide pillars 3 are embedded in the bottom of the moving platen 1. A core 5 is detachably installed on the upper surface of the fixed platen 2. The surface of the core 5 is provided with an injection cavity 11. Two symmetrically distributed slide blocks 6 are slidably installed on both sides of the core 5. The surface of the slide block 6 is provided with multiple inclined guide pillar holes 10. The inclined guide pillar holes 10 are vertically aligned with the inclined guide pillars 3. The inclined guide pillars 3 and the inclined guide pillar holes 10 are used to position the slide blocks 6 when the mold is closed, thereby ensuring that the mold slide insert 8 moves into place.

[0021] A connecting slider 9 is installed between two adjacent sliding blocks 6 at the ends. The connecting slider 9 drives the sliding blocks 6 to slide on the surface of the core 5. Multiple sliding inserts 8 are slidably engaged on the side of the sliding blocks 6 facing the injection cavity 11. The sliding inserts 8 slide in contact with the core 5 and one end extends into the inside of the injection cavity 11. The sliding blocks 6 drive the sliding inserts 8 to make linear displacement along the length direction of the sliding inserts 8, thereby realizing the simultaneous movement of multiple sliding inserts 8.

[0022] Multiple insert sliding grooves 14 are provided on both sides of the injection cavity 11. The sliding insert 8 is slidably installed inside the insert sliding groove 14. A sliding insert pressure plate 4 is provided above the insert sliding groove 14. The sliding insert pressure plate 4 is connected to the core 5 by screws. The sliding insert pressure plate 4 is used to restrict the position of the sliding insert 8 to prevent the sliding insert 8 from falling out of the insert sliding groove 14.

[0023] The side of the sliding block 6 connected to the sliding insert 8 is provided with a sliding guide groove 12. The bottom of the end of the sliding insert 8 connected to the sliding block 6 is provided with a sliding engagement groove 13. The sliding engagement groove 13 at the bottom of the end of the sliding insert 8 engages and slides above the edge of the sliding guide groove 12, and the end of the sliding engagement groove 13 slides and engages inside the sliding guide groove 12. The sliding engagement groove 13 ensures that the sliding block 6 can drive the sliding insert 8 to move simultaneously when it moves, and the existence of the sliding guide groove 12 ensures that the sliding block 6 will not interfere with the sliding insert 8 when it moves.

[0024] During injection molding, the mold is first closed. As the mold closes, the moving platen 1 moves closer to the fixed platen 2. During this process, the bottom end of the inclined guide post 3 first enters the inclined guide post hole 10. After entering the inclined guide post hole 10, the inclined guide post 3 slides and compresses with the sliding block 6. At this time, the sliding block 6 moves towards the injection cavity 11, and pushes the sliding insert 8 to slide inside the insert sliding groove 14. Simultaneously, the end of the sliding insert 8 connected to the sliding block 6 through the sliding locking groove 13 slides along the length of the sliding guide groove 12. When the moving template 1 and the fixed template 2 are closed, the raw material is extruded and injected into the injection cavity 11. After the product cools and solidifies, the moving template 1 moves upward. After the moving template 1 moves upward, the sliding block 6 loses the extrusion of the inclined guide post 3. At this time, the sliding block 6 resets and drives the sliding insert 8 to reset, separating the sliding insert 8 from the product. Multiple sliding inserts 8 can be moved simultaneously by one sliding block 6, and the sliding block 6 and the sliding insert 8 will not interfere with each other. This simplifies the optimization of mold components, reduces mold design and manufacturing costs, and reduces mold component maintenance costs.
