Description

Technical Field

[0001] This utility model relates to the technical field of production applications, specifically to a mold guide structure with anti-misalignment features. Background Technology

[0002] The mold guide structure has an anti-misalignment function, which mainly ensures that key components such as the mold core and cavity can be precisely aligned during the mold opening and closing process, avoiding product defects caused by misalignment.

[0003] When dealing with products that require misalignment of upper and lower cavities, the conventional approach to ensure the required amount of misalignment is to add a mold position guide structure during mold design. However, this method has certain limitations. If the mold is misaligned during on-site mold assembly, the risk of producing defective products is very high. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mold guide structure with anti-misalignment features, which solves the problem that conventional mold structures require checking the relative position of the mold when assembling disc-shaped parts with mold misalignment requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold guide structure with anti-misalignment, including a punch and a die, a guide sleeve is provided below the punch, and the bottom surface of the guide sleeve is in contact with and fixedly connected to the top surface of the die. Guide keyways are provided inside both ends of the bottom surface of the guide sleeve and the top surface of the die. The bottom surface of the guide sleeve and the guide keyways on the die are fixedly in contact with each other and perpendicular to each other.

[0006] Preferably, an ejector is placed inside the die cavity. The width of the ejector is greater than the inner diameter of the guide sleeve, and the inner diameter of the guide sleeve is smaller than the width of the die cavity. A die core is fixedly installed inside the ejector, and the upper end of the die core passes through the inside of the ejector to the top of the ejector. A punch mandrel is fixedly installed inside the punch, and a punch filler is placed inside the top surface of the punch mandrel. The workpiece is placed inside the die cavity and above the die core, thereby facilitating the stamping of the workpiece by the punch head and the ejector.

[0007] Preferably, the positions of the adjacent guide keyways inside the bottom surface of the guide sleeve and the top surface of the die are arranged differently, which can effectively prevent the die from misalignment during use.

[0008] Preferably, the shape of the punch consists of three 90-degree straight edges and a circle, and the shape of the guide sleeve consists of three 90-degree straight edges and a circle. When the punch and the guide sleeve are connected, the three 90-degree straight edges and the circle are connected to each other, so that the punch and the guide sleeve are locked by shape when working and will not be misaligned.

[0009] Preferably, the diameter of the punch is matched with the inner diameter of the guide sleeve, so that the punch can be positioned stably during use.

[0010] This utility model provides a mold guide structure with anti-misalignment features. It has the following beneficial effects:

[0011] 1. The mold guide structure with anti-misalignment, when using the mold guide structure with anti-misalignment, anti-misalignment is achieved by changing the position arrangement of the guide keyway on the guide sleeve and the mold.

[0012] 2. This mold guide structure with anti-misalignment means that when using the mold guide structure with anti-misalignment, the original common guide keyway positions are adjusted to ensure that the mold is not misaligned during assembly. Attached Figure Description

[0018] 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. Example 1

[0019] Please see Figure 1-4This utility model provides a mold guide structure with anti-misalignment, including a punch 3 and a die 7. A guide sleeve 4 is provided below the punch 3, and the bottom surface of the guide sleeve 4 is in contact with and fixedly connected to the top surface of the die 7. Guide keyways 5 are provided inside both ends of the bottom surface of the guide sleeve 4 and the top surface of the die 7. The bottom surface of the guide sleeve 4 and the guide keyways 5 on the die 7 are fixedly in contact with each other and perpendicular to each other. The positions of adjacent guide keyways 5 inside the bottom surface of the guide sleeve 4 and the top surface of the die 7 are different. The diameter of the punch 3 matches the internal diameter of the guide sleeve 4. The punch 3 and the guide sleeve 4 are locked by shape during operation and will not misalign. The connection between the guide sleeve 4 and the die 7 is locked by the vertical guide keyways 5 and will not misalign. At the same time, the different positions of adjacent guide keyways 5 on the same surface can effectively improve the misalignment phenomenon during operation. Example 2

[0020] To facilitate stable stamping of workpiece 6, in this embodiment, as follows: Figure 1-4 As shown, a ejector 9 is placed inside the die 7. The width of the ejector 9 is greater than the internal diameter of the guide sleeve 4, and the internal diameter of the guide sleeve 4 is smaller than the width of the die 7. A die core 8 is fixedly installed inside the ejector 9, and the upper end of the die core 8 passes through the interior of the ejector 9 to the top of the ejector 9. A punch mandrel 2 is fixedly installed inside the punch 3. A punch filler block 1 is placed inside the top surface of the punch mandrel 2. A workpiece 6 is placed inside the die 7 and above the die core 8. The shape of the punch 3 consists of three 90-degree straight edges and a circle. The shape of the guide sleeve 4 consists of three 90-degree straight edges and a circle. When the punch 3 and the guide sleeve 4 are connected, the three 90-degree straight edges and the circle are connected to each other. The workpiece 6 is placed on the ejector 9, and then the punch 3 is made to punch downwards, and the punch mandrel 2 is used to punch the workpiece.

[0021] It should be noted that in this embodiment, when using a mold guide structure with error prevention, such as Figure 1-4 As shown, the punch 3 and guide sleeve 4 are locked by shape during operation, preventing misalignment. The connection between the guide sleeve 4 and the die 7 is locked by the vertical guide keyway 5, preventing misalignment. At the same time, the adjacent guide keyways 5 on the same surface are arranged in different positions, which can effectively reduce the occurrence of misalignment during operation. The workpiece 6 is placed on the ejector 9, and then the punch 3 is made to punch downwards, and the punch mandrel 2 is used to punch the workpiece.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
