Description

Technical Field

[0001] The utility model belongs to the technical field of metal terminal injection molding, in particular to a metal terminal injection molding device. Background Art

[0002] Metal terminals are a common type of wiring terminals. Common specifications include U-shaped and cylindrical. Metal terminals can transmit electrical signals or conduct electricity, so they are widely used in various fields such as industry, communications and new energy vehicles. Injection molding equipment is usually required to shape the materials during production.

[0003] The existing injection molding equipment cannot quickly remove the metal terminals after molding them. Since the metal terminals are small in size and a large number of them are molded at one time, the staff need to take them out one by one, which will increase the staff's workload, consume a lot of time, and reduce the output of the metal terminals. Therefore, we propose a metal terminal injection molding device. Utility Model Content

[0004] The purpose of the utility model is to provide a metal terminal injection molding device, which sets a flipping component, specifically, starts a motor to drive the rotating rod to rotate counterclockwise, and the gear rotates together and drives the lower mold to flip to the back side through the connecting seat. When the top of the lower mold contacts the limit support rod, it stops flipping, and the metal terminals formed inside fall into the collection box for collection, so that the metal terminals can be quickly taken out, and the staff does not need to take them out one by one, thereby improving work efficiency and solving the problem that the metal terminals cannot be taken out quickly after being formed, and the staff need to take them out one by one, which increases the workload of the staff and consumes a lot of time.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

The left and right sides of the top of the base 1 are fixedly connected with fixed blocks 133. The right side of the fixed block 133 on the right side is fixedly connected with a motor 134. The two fixed blocks 133 are provided with rotating holes inside, and the inner walls of the rotating holes are rotatably connected with a rotating rod 136. By setting the flip assembly 13, specifically starting the motor 134 to drive the rotating rod 136 to rotate counterclockwise, the gear 137 rotates together and drives the lower mold 12 to flip to the back side through the connecting seat 131. When the top of the lower mold 12 contacts the limiting support rod 135 and stops flipping, the metal terminals formed inside fall into the collection box 113 for collection, so that the metal terminals can be quickly taken out without the need for staff to take them out one by one, thereby improving work efficiency.

[0029] The four corners of the bottom of the lower mold 12 are fixedly connected with contact blocks 121, the bottom of the contact block 121 contacts with a lifting seat 122, the four corners of the bottom of the lifting seat 122 are fixedly connected to the surface of the base 1 through support rods, and a plurality of grooves 123 are opened at the bottom of the lower mold 12, and the inner walls of the plurality of grooves 123 are fixedly connected with arc blocks 124.

[0030] The outer side of the connecting seat 131 is rotatably connected to the supporting seat 132, the bottom of the supporting seat 132 is fixedly connected to the top of the lifting seat 122, the backs of the two fixing blocks 133 are fixedly connected to the limited support rod 135, and the outer surface of the rotating rod 136 is fixedly connected to two gears 137.

[0034] A specific application of this embodiment is:

[0035] When in use, the material to be injected is placed on the lower mold 12, and then the hydraulic cylinder 111 is started to drive the upper mold 112 to move downward, and the material is injected by cooperating with the lower mold 12 to form the metal terminal. After forming, the upper mold 112 is reset upward, and then the motor 134 is started to drive the rotating rod 136 to rotate counterclockwise, and the gear 137 rotates together. Since the outer surface of the connecting seat 131 is fixedly connected with a convex tooth and meshed with the gear 137, the gear 137 will drive the connecting seat 131 to rotate counterclockwise through the convex tooth, and the connecting seat 131 will rotate on the supporting seat 132, and drive the lower mold 12 to flip to the back side. When the top of the lower mold 12 contacts the limiting support rod 135, it stops flipping, and the limiting support rod 135 supports the lower mold 12. After the lower mold 12 is flipped, the metal terminal formed inside falls into the collection box 113 for collection. The metal terminals are collected, so that the metal terminals can be quickly taken out, and the staff does not need to take them out one by one, thereby improving work efficiency. Subsequently, the motor 2 143 is started to drive the elliptical roller 145 to rotate through the rotating shaft 144. The elliptical roller 145 will indirectly contact and collide with the arc block 124 during the rotation. Since the arc block 124 is elastically set, the elliptical roller 145 can leave smoothly. Such reciprocating can make the lower mold 12 produce a vibration effect, thereby shaking off the metal terminals attached to the lower mold 12, improving the unloading rate of the lower mold 12, avoiding the situation where there are residues inside, and the material unloading efficiency can be improved again through vibration. Finally, the motor 1 134 is started to rotate in the opposite direction, and the gear 137 drives the connecting seat 131 to rotate in the opposite direction, so that the lower mold 12 is flipped and reset to the front side. When the contact block 121 at the bottom of the lower mold 12 contacts the lifting seat 122 and stops, the injection molding work can be carried out again.
