Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a mold. Background Technology

[0002] In the existing process, the workpiece needs to undergo processes such as stamping, punching, and blanking, ultimately forming a workpiece with through holes that match the blanked shape.

[0003] Stamping is typically used to engrave text, serial numbers, trademarks, dates, batch numbers, and other information on parts for easy product identification, tracking, and management. For example, it can indicate the manufacturer, production date, and production batch. Punching is mostly used to create holes or cut pre-defined shapes in parts. These holes can be used for assembly, connection, ventilation, drainage, and other purposes. Blanking refers to the process of cutting raw materials into predetermined shapes and sizes using a die during manufacturing. In actual manufacturing, this involves multiple processing steps performed sequentially by moving the workpiece.

[0004] However, during the processing, processing residue will be left after the workpiece is processed. This residue will become a loss, resulting in resource waste and increased manufacturing costs. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a mold that has the advantages of saving the number of molds and reducing material waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mold includes a top plate and a bottom plate disposed opposite to each other, characterized in that it further includes a blanking module and a drilling module disposed between the top plate and the bottom plate, the blanking module and the drilling module being disposed along a first direction, the first direction being parallel to the length direction of the top plate; the blanking module includes a first processing unit and a second processing unit, the first processing unit and the second processing unit being disposed between the top plate and the bottom plate, the first processing unit and the second processing unit being disposed on the bottom surface of the top plate, the projections of the first processing unit and the second processing unit on the top plate having the same shape, the first processing unit and the second processing unit including a head and a root, the head of the first processing unit being farther away from the head of the second processing unit relative to the root of the first processing unit; the drilling module being located behind the blanking module along the first direction. The blanking module and the drilling module are arranged in sequence, with the blanking process performed first and the drilling process performed later. This combines the three processes into one mold, reducing the number of molds required for processing. In addition, by reversing the first and second processing units contained in the blanking module, that is, the head of the first processing unit is far away from the head of the second processing unit relative to the root of the first processing unit, the first and second processing units are staggered during blanking, which improves the utilization rate of materials and reduces production costs.

[0008] Optionally, the first processing unit and the second processing unit protrude from the bottom surface of the top plate;

[0009] The base plate is provided with a first groove and a second groove. The first groove is adapted to the first processing unit, and the second groove is adapted to the second processing unit. The projection of the first processing unit on the base plate is located within the first groove, and the projection of the second processing unit on the base plate is located within the second groove. The first groove and the second groove are respectively used to accommodate the parts cut by the first and second processing units during the blanking process. The fact that the projections of the first and second processing units on the base plate are located within the first groove and the second groove, respectively, ensures that the first and second processing units will not tilt due to squeezing or collision with the base plate during processing, thereby improving the stability and safety of the mold.

[0010] Optionally, the depth of the first groove is greater than the height of the first processing unit protruding from the bottom surface of the top plate, and the depth of the second groove is greater than the height of the second processing unit protruding from the bottom surface of the top plate. The first groove and its depth being greater than the height of the first processing unit protruding from the bottom surface of the top plate are for accommodating the cut raw material; that is, the depth of the first groove is greater than or equal to the sum of the height of the first processing unit protruding from the bottom surface of the top plate and the thickness of the raw material. Similarly, the depth of the second groove is greater than or equal to the sum of the height of the second processing unit protruding from the bottom surface of the top plate and the thickness of the raw material.

[0011] Optionally, the top plate can move between a first position and a second position, with the top plate in the first position being farther away from the bottom plate relative to the top plate in the second position; when the top plate is in the first position, there is a first distance between the top plate and the bottom plate, and when the top plate is in the second position, there is a second distance between the top plate and the bottom plate, where the first distance is greater than the second distance. By controlling the position movement of the top plate, the distance between the top plate and the bottom plate can be varied between the first and second distances, thereby enabling the processing of raw materials.

[0012] Optionally, the first processing unit and the second processing unit are arranged along a first direction, with the axis of symmetry of the first processing unit parallel to the axis of symmetry of the second processing unit. The parallel arrangement of the axes of symmetry of the first and second processing units allows for the creation of parallel blanking holes on the raw material during the blanking process, improving raw material utilization efficiency and reducing production costs.

[0013] Optionally, the minimum distance between the first processing unit and the second processing unit is greater than or equal to 1 mm and less than or equal to 5 mm. The minimum distance between the first processing unit and the second processing unit is used to ensure that the raw material will not break during processing due to the small gap between two adjacent discharge holes, thereby improving the stability of the mold. The maximum distance between the first processing unit and the second processing unit is used to improve the utilization rate of raw materials and reduce production costs.

[0014] Optionally, the axis of symmetry of the first processing unit or the second processing unit forms an inclination angle with the first direction, the inclination angle being greater than 45° and less than 90°. An angle greater than 45° between the axis of symmetry of the first processing unit and the second processing unit and the first direction can reduce material waste caused by inclination and improve raw material utilization.

[0015] Optionally, the drilling module includes a punching unit disposed on the bottom surface of the top plate and facing the bottom plate. The punching unit includes multiple punching heads. The punching heads are used to form the required through holes in the raw material during the movement of the top plate to the bottom plate, thereby realizing the punching process.

[0016] Optionally, the drilling module further includes an engraving unit disposed on the bottom surface of the top plate, with at least a portion of the engraving unit protruding from the bottom surface of the top plate. The distance by which the engraving unit protrudes from the bottom surface of the top plate is less than the thickness of the raw material, so as to form an engraving on the raw material without penetrating it, thereby realizing the engraving process.

[0017] Optionally, the system also includes a sliding column and a sliding sleeve. The sliding column is fixed to the base plate, and the sliding sleeve is fixed to the top plate. The sliding column and the sliding sleeve are adapted to each other, and the sliding column can slide within the sliding sleeve. The sliding column and the sliding sleeve are used to fix the movement direction of the top plate and provide movement limit for the top plate, ensuring that the top plate moves back and forth between a first position and a second position. Furthermore, the top plate maintains a right angle between its movement direction and the base plate during movement, preventing the top plate from tilting and improving mold stability.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0025] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0026] like Figure 1 and Figure 2 As shown, a mold is provided, including a top plate 10 and a bottom plate 20 disposed opposite to each other. The mold is characterized by further including a blanking module 30 and a drilling module 40 disposed between the top plate 10 and the bottom plate 20. The blanking module 30 and the drilling module 40 are disposed along a first direction X, which is parallel to the length direction of the top plate 10. The arrangement of the blanking module 30 and the drilling module 40 allows three processes that originally required three molds to be combined into one mold, reducing the number of molds needed and improving production efficiency.

[0027] The material feeding module 30 includes a first processing unit 31 and a second processing unit 32, which are disposed between the top plate 10 and the bottom plate 20. The first processing unit 31 and the second processing unit 32 are located on the bottom surface of the top plate 10. The projections of the first processing unit 31 and the second processing unit 32 on the top plate 10 have the same shape. Each processing unit 31 and the second processing unit 32 includes a head and a root. The head of the first processing unit 31 is farther away from the head of the second processing unit 32 relative to its root. By reversing the arrangement of the first processing unit 31 and the second processing unit 32 within the material feeding module 30—that is, the head of the first processing unit 31 is farther away from its root relative to the head of the second processing unit 32—the first processing unit 31 and the second processing unit 32 are staggered during material feeding, improving material utilization and reducing production costs.

[0028] The drilling module 40 is located after the blanking module 30 along the first direction X. The blanking process is performed first, followed by the drilling process, according to the sequence, enabling multiple processing techniques to be performed within the same mold, thus reducing the number of molds required.

[0029] The first processing unit 31 and the second processing unit 32 protrude from the bottom surface of the top plate 10. The bottom plate 20 is provided with a first groove 21 and a second groove 22. The first groove 21 is adapted to the first processing unit 31, and the second groove 22 is adapted to the second processing unit 32. The projection of the first processing unit 31 onto the bottom plate 20 is located within the first groove 21, and the projection of the second processing unit 32 onto the bottom plate 20 is located within the second groove 22. Through this arrangement, the first groove 21 and the second groove 22 are respectively used to accommodate the parts produced by the first processing unit 31 and the second processing unit 32 during the blanking process. The fact that the projections of the first processing unit 31 and the second processing unit 32 onto the bottom plate 20 are located within the first groove 21 and the second groove 22 respectively ensures that the first processing unit 31 and the second processing unit 32 will not tilt due to pressure or collision with the bottom plate 20 during processing, thus improving the stability and safety of the mold. In this embodiment, the first groove 21 and the second groove 22 also include a head and a root. The head of the first groove 21 corresponds to the head of the first processing unit 31, and the root of the first groove 21 corresponds to the root of the first processing unit 31. Similarly, the head of the second groove 22 corresponds to the head of the second processing unit 32, and the root of the second groove 22 corresponds to the root of the second processing unit 32. That is, the head of the first groove 21 and the root of the second groove 22 are close to each other, the head of the first groove 21 is closer to the root of the second groove 22 than the root of the first groove 21, and the root of the first groove 21 is closer to the head of the second groove 22 than the head of the first groove 21. Through the above arrangement, the utilization rate of the first groove 21 and the second groove 22 provided on the base plate 20 is improved, thereby improving the utilization rate of raw materials and reducing production costs.

[0030] The depth of the first groove 21 is greater than the height of the first processing unit 31 protruding from the bottom surface of the top plate 10, and the depth of the second groove 22 is greater than the height of the second processing unit 32 protruding from the bottom surface of the top plate 10. The first groove 21 and its depth being greater than the height of the first processing unit 31 protruding from the bottom surface of the top plate 10 are used to accommodate the cut raw material. That is, the depth of the first groove 21 is greater than or equal to the sum of the height of the first processing unit 31 protruding from the bottom surface of the top plate 10 and the thickness of the raw material. Similarly, the depth of the second groove 22 is greater than or equal to the sum of the height of the second processing unit 32 protruding from the bottom surface of the top plate 10 and the thickness of the raw material. In this embodiment, the depth of the first groove 21 is 3mm, the height of the first processing unit 31 and the second processing unit 32 protruding from the bottom surface of the top plate 10 is 1mm, and the thickness of the raw material plate is 1mm. Through the above arrangement, the first groove 21 can cooperate with the first processing unit 31, and the second groove 22 can cooperate with the second processing unit 32, realizing the material unloading process.

[0031] The top plate 10 is movable between a first position and a second position. When the top plate 10 is in the first position, it is farther from the bottom plate 20 than when it is in the second position. When the top plate 10 is in the first position, there is a first distance between the top plate 10 and the bottom plate 20. When the top plate 10 is in the second position, there is a second distance between the top plate 10 and the bottom plate 20, and the first distance is greater than the second distance. The distance between the top plate 10 and the bottom plate 20 is controlled by moving the top plate 10, changing between the first and second distances, thus processing the raw materials. When the top plate 10 is in the first position, the distance between the top plate 10 and the bottom plate 20 reaches its maximum value; when the top plate 10 is in the second position, the distance between the top plate 10 and the bottom plate 20 reaches its minimum value. This position also corresponds to the position where the mold performs different processing steps on the raw materials.

[0032] like Figure 3 As shown, the first processing unit 31 and the second processing unit 32 are arranged along the first direction X, and the axis of symmetry of the first processing unit 31 is parallel to the axis of symmetry of the second processing unit 32. The axes of symmetry of the first processing unit 31 and the second processing unit 32 are parallel to each other, allowing them to be arranged in parallel. This enables parallel blanking holes to be obtained on the raw material during the blanking process, improving the utilization efficiency of the raw material and reducing production costs. In this embodiment, without this mold, the step distance between the through holes formed on the raw material in the two blanking processes is 103.738 (mm), and the width of the raw material used is 189.925 (mm), resulting in a raw material utilization rate of 59.916%. With this mold, the step distance between the through holes formed on the raw material in the two blanking processes is 119.127 (mm), and the width of the raw material used is 261.662 (mm). However, because the production of one part per blanking process is changed to the production of two parts per blanking process, the raw material utilization rate is 75.744%. Through the above comparison, this mold can improve the utilization rate of raw materials, reduce the amount of waste generated by the same amount of raw materials, reduce the average raw material area required to produce a single part, and reduce production costs.

[0033] The minimum distance between the first processing unit 31 and the second processing unit 32 is greater than or equal to 1 mm and less than or equal to 5 mm. The minimum distance between the first processing unit 31 and the second processing unit 32 is used to ensure that the raw material will not break during processing due to the small gap between two adjacent feeding holes, thereby improving the stability of the mold. The maximum distance between the first processing unit 31 and the second processing unit 32 is used to improve the utilization rate of raw materials and reduce production costs.

[0034] The axis of symmetry of the first processing unit 31 or the second processing unit 32 forms an inclination angle 33 with the first direction X, the inclination angle 33 being greater than 45° and less than 90°. An angle greater than 45° between the axis of symmetry of the first processing unit 31 and the second processing unit 32 and the first direction X can reduce material waste caused by inclination and improve raw material utilization. The closer the inclination angle 33 of the first processing unit 31 and the second processing unit 32 is to 90°, the smaller the requirement for the length of the raw material and the larger the requirement for the width of the raw material. In this embodiment, the inclination angle 33 of the first processing unit 31 and the second processing unit 32 is 75°.

[0035] The drilling module 40 includes a punching unit 41, which is disposed on the bottom surface of the top plate 10 and faces the bottom plate 20. The punching unit includes multiple punching heads. The punching heads are used to form the required through holes in the raw material during the movement of the top plate 10 towards the bottom plate 20, thereby realizing the punching process.

[0036] The drilling module 40 also includes an engraving unit 42, which is disposed on the bottom surface of the top plate 10. At least a portion of the engraving unit 42 protrudes from the bottom surface of the top plate 10. The distance by which the engraving unit 42 protrudes from the bottom surface of the top plate 10 is less than the thickness of the raw material, so as to form an engraving on the raw material without penetrating it, thus realizing the engraving process.

[0037] The mold also includes a sliding pillar 50 and a sliding sleeve 51. The sliding pillar 50 is fixed to the base plate 20, and the sliding sleeve 51 is fixed to the top plate 10. The sliding pillar 50 and the sliding sleeve 51 are adapted to each other, and the sliding pillar 50 can slide within the sliding sleeve 51. The sliding pillar 50 and the sliding sleeve 51 are used to fix the moving direction of the top plate 10 and provide a movement limit for the top plate 10, ensuring that the top plate 10 moves back and forth between a first position and a second position. Furthermore, the top plate 10 maintains a right angle between its moving direction and the base plate 20 during movement, preventing the top plate 10 from tilting and improving mold stability.

[0038] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
