Description

Technical Field

[0001] This utility model belongs to the field of terminal block processing technology, and in particular relates to a rapid prototyping mold for terminal blocks. Background Technology

[0002] Terminal forming molds are special molds used to manufacture electrical connection terminals. They belong to the category of precision stamping molds. Their core function is to process metal sheets (such as copper, aluminum or iron alloys) into terminals with specific shapes and structures through stamping, extrusion, bending and other processes, so as to realize reliable connections between wires and between wires and devices in electrical equipment.

[0003] In the stamping process of terminal blocks, gravity ejection or single ejector pin ejection is often used, relying on the workpiece's own weight to push the material. When the terminal block is small or has a barbed structure, it is easy to get stuck at the ejection port. Although single ejector pin ejection can push the workpiece out of the center, it is easy to cause deformation for irregularly shaped terminals (such as L-shaped and U-shaped). Therefore, it is necessary to provide a terminal block rapid prototyping mold that uses a stamping action linked to the ejection structure. After a single stamping, the material is ejected at an angle to prevent the ejection jamming phenomenon and ensure stable and rapid forming of the terminal block. Utility Model Content

The material ejection assembly includes an extrusion plate fixedly connected to both sides of the bottom of the lower pressure seat, and a slidable material ejection plate is provided through both sides of the inner cavity of the material ejection port. The top of the material ejection plate is provided with a wedge-shaped hole adapted to the extrusion plate. A tension spring is welded to the side of the material ejection plate away from the material ejection port, and the end of the tension spring away from the material ejection plate is welded to the mold base.

[0021] In the following description, embodiments of the rapid prototyping mold for the terminal blocks of this invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a rapid prototyping mold for terminal blocks according to an embodiment of the present invention. The mold includes a mold base 1. A liftable lower pressure seat 2 is mounted on the top of the mold base 1. Guide rods 6 are fixedly connected to both sides of the top of the mold base 1. The lower pressure seat 2 is slidably connected to the surface of the guide rods 6. A spring 7 is sleeved on the surface of the guide rods 6. The top and bottom ends of the spring 7 are welded to the lower pressure seat 2 and the mold base 1, respectively. Threaded grooves are formed at the four corners of the top of the lower pressure seat 2. A stamping assembly 3 is mounted on the top of the mold base 1. The stamping assembly 3 includes a lower mold 31 fixedly connected to the top of the mold base 1. A clamping plate 32 is engaged on the top of the lower mold 31. Bolts 33 are threaded through the four corners of the top of the clamping plate 32. The bottom ends of the bolts 33 extend to the bottom of the clamping plate 32 and are threadedly connected to the lower mold 31. The tops of the lower mold 31 and the clamping plate 32 are provided with pattern holes adapted to an upper mold 34. Through the combined use of the clamping plate 32, bolts 33, and upper mold 34, a punched shape is provided for the terminal block. This allows the terminal block material to be quickly formed under the action of the preset mold hole. The bottom of the lower pressure seat 2 is fixedly connected to the upper mold 34. The center of the bottom of the mold base 1 is provided with a material ejection port 4. Both sides of the inner cavity of the material ejection port 4 are provided with material ejection components 5. The material ejection components 5 include extrusion plates 51 fixedly connected to both sides of the bottom of the lower pressure seat 2. Both sides of the inner cavity of the material ejection port 4 are provided with slidable material ejection plates 52. The opposite side of the two material ejection plates 52 is provided with an inclined surface. The surface of the extrusion plate 51 is flush with the wedge. The inner wall of the shaped hole 53 fits tightly. Through the cooperation of the ejector plate 52 and the extrusion plate 51, the terminal in the inner cavity of the ejector port 4 is obliquely extruded, so that the terminal in the inner cavity of the ejector port 4 can be quickly disengaged, preventing the terminal from getting stuck or blocked. The top of the ejector plate 52 is provided with a wedge-shaped hole 53 that matches the extrusion plate 51. A tension spring 54 is welded to the side of the ejector plate 52 away from the ejector port 4. The end of the tension spring 54 away from the ejector plate 52 is welded to the mold base 1.

[0023] Working Principle: In use, the user fixes the lower pressure seat 2 to the stamping end of the stamping machine via the threaded groove on its top, and fixes the mold base 1 to the top of the processing table of the stamping equipment. Then, the terminal material is passed between the lower mold 31 and the clamping plate 32. The stamping end of the stamping equipment drives the lower pressure seat 2 to press downwards. During the descent, the lower pressure seat 2 drives the upper mold 34 to act on the surface of the terminal material. Due to the mold holes on the top of the lower mold 31 and the clamping plate 32, the terminal is stamped and formed. The formed terminal falls from the inner cavity of the ejector port 4. During the upward reset process of the lower pressure seat 2, the lower pressure seat 2 drives the two extrusion plates 51 to move upwards. The extrusion plate 51 presses against the inner wall of the ejector plate 52, causing the ejector plate 52 to slide. During the movement of the two ejector plates 52 towards each other, the ejector plate 52 acts as a scraper on the terminal block located in the inner cavity of the ejector port 4. At the same time, due to the action of the inclined surface at the end of the ejector plate 52, the scraping direction is downward, which allows the terminal block to fall quickly from the inner cavity of the ejector port 4. This also prevents the terminal block from getting stuck in the inner cavity of the ejector port 4. When the lower press seat 2 presses down again, the surface of the extrusion plate 51 releases the pressure on the ejector plate 52, causing the tension spring 54 to rebound and pull the ejector plate 52 back to its original position, thereby avoiding obstruction to the secondary pressing of the upper mold 34.

[0024] In summary, this rapid prototyping mold for terminal blocks, through the combined use of the mold base 1, the lower pressure seat 2, and the stamping component 3, punches and shapes the raw material of the terminal blocks. Simultaneously, with the cooperation of the ejector component 5, the punched terminal blocks in the inner cavity of the ejector port 4 are extruded and ejected, thus achieving the purpose of rapid prototyping and ejection and preventing material jamming and blockage.
