Description

Technical Field

[0001] The utility model belongs to the field of molds, relates to a lower track cover plate, and particularly relates to an improved structure of the lower track cover plate. Background Technique

[0002] An automatic lead trimmer is a device for trimming leads of products. For example, a chip automatic lead trimmer is used to cut off surplus materials such as gates on chips.

[0003] In the existing chip automatic lead trimmer, the structure design of the lower track cover plate is not reasonable enough. During the feeding or discharging process, the chip products are easily stuck on the lower track cover plate, resulting in problems such as lead deformation, lead crush, product crack, and product corner breakage of the chip products. Summary of the Invention

[0004] The purpose of the utility model is to provide an improved structure of a lower track cover plate to solve the above problems for the problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: an improved structure of a lower track cover plate, including a lower track cover plate main body, characterized in that the lower track cover plate main body is made of alloy steel, and the A surface on the lower track cover plate is arranged in an inclined structure;

[0006] The center of the lower track cover plate has a mounting hole for facilitating installation in an automatic lead trimmer;

[0007] A plurality of positioning holes for reducing the weight and for positioning are opened on the lower track cover plate;

[0008] The A surface of the lower track cover plate is located on the side corresponding to the mounting hole.

[0009] In the above-mentioned improved structure of the lower track cover plate, the A surface of the lower track cover plate is arranged in a downward inclined structure from left to right, and the above-mentioned inclined structure is an outer arc structure, a straight line structure, or an inner arc structure.

[0010] In the above-mentioned improved structure of the lower track cover plate, the lower track cover plate is arranged in an integrally formed structure and is made of alloy steel material.

[0011] Compared with the prior art, the improved structure of the present lower track cover plate is simple. By designing the A surface of the lower track cover plate in a downward inclined structure from left to right, it prevents the jamming of chip products, reduces the number of defective products of chip products, and improves the lead trimming efficiency. Brief Description of the Drawings

[0012] Figure 1 It is a three-dimensional schematic diagram of the improved structure of the present lower track cover plate.

[0013] Figure 2It is a partial side view schematic diagram of the improved structure of the lower track cover plate.

[0014] In the figure, 1 is the main body of the lower track cover plate; 2 is the mounting hole; 3 is the positioning hole. Specific implementation manner

[0015] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0016] As Figure 1 shown, the improved structure of the lower track cover plate of the present invention includes the main body 1 of the lower track cover plate, which is made of alloy steel. The A surface of the lower track cover plate is inclined. The center of the lower track cover plate has a mounting hole 2 for facilitating installation in an automatic lead frame trimming machine. A number of positioning holes 3 for reducing the weight and for positioning are provided on the lower track cover plate. The A surface of the lower track cover plate is located on the side corresponding to the mounting hole 2.

[0017] The above structure is simple. Through the design of the inclined structure of the A surface of the lower track cover plate from left to right downward, it can prevent the jamming of chip products, reduce the number of defective products of chip products, and improve the lead frame trimming efficiency.

[0018] Further elaborating, as Figure 2 shown, in order to achieve smooth discharging or feeding of chip products, the A surface of the lower track cover plate is provided with an inclined structure from left to right downward. The above inclined structure is an outer arc structure, a straight line structure, or an inner arc structure. The above structure makes the A surface of the lower track cover plate have a guiding effect, effectively ensuring the smooth discharging or feeding of chip products.

[0019] Further elaborating, in order to improve the strength and stability of the lower track cover plate, the lower track cover plate is provided with an integrally formed structure and is made of alloy steel material.

[0020] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0021] Although terms such as the main body 1 of the lower track cover plate, the mounting hole 2, and the positioning hole 3 are used more in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
