Description

Technical Field

[0001] This utility model relates to the field of injection molding processing technology, and in particular to an injection molding terminal pressing and cutting device. Background Technology

[0002] In the production process of injection molded terminals, the hardware part of the terminal needs to be intermittently placed in the mold using a strip, and the hardware part is partially covered by injection molding to improve the structural stability of the hardware.

[0003] The hardware part of the terminal often contains multiple parallel hardware lines. The gap between two adjacent hardware lines is relatively small. Under the impact force of injection molding, it is easy to cause deformation and short circuit of the two adjacent hardware lines. Therefore, a hardware bridge is often left between two adjacent hardware lines to limit the two adjacent hardware lines and avoid deformation during injection molding.

[0004] In addition, material bridges need to be cut off after injection molding to avoid short circuits. Because the distance between two adjacent material bridges is small, the cutting distance of the punching blades is often too large, making it impossible to quickly cut off the material bridges, which needs to be improved. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a device for pressing and cutting injection molded part terminals, which can press and cut the material bridges of injection molded parts terminals, thereby improving production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a device for pressing and cutting injection molded part terminals, comprising: a base, a pressure plate, a first cutting sleeve, a second cutting sleeve, a first transverse cutting blade, a second transverse cutting blade, a first longitudinal cutting blade, and a second longitudinal cutting blade. A material guide groove is transversely arranged on the base. The pressure plate is vertically mounted on the base and located on one side of the material guide groove. The material strip is disposed in the material guide groove. The terminals are spaced apart on one side of the material strip and located below the front end of the pressure plate. A lifting seat is provided on the pressure plate. The first and second cutting sleeves are spaced apart along the length of the material guide groove on the lifting seat and located at the end... Above the path of the component, the terminal is provided with a first hardware line extending longitudinally and a second hardware line extending laterally. A first material bridge is provided between two adjacent first hardware lines, and a second material bridge is provided between two adjacent second hardware lines. The first transverse blanking blade is vertically arranged in the first blade holder and corresponds to the odd number of the first material bridge. The second transverse blanking blade is vertically arranged in the second blade holder and corresponds to the even number of the first material bridge. The first longitudinal blanking blade is arranged in the first blade holder and corresponds to the odd number of the second material bridge. The second longitudinal blanking blade is arranged in the second blade holder and corresponds to the even number of the second material bridge.

[0007] In a preferred embodiment of this utility model, the distance between the first blade sleeve and the second blade sleeve corresponds to the distance between the two adjacent ends.

[0008] In a preferred embodiment of the present invention, the base is provided with a first telescopic cylinder for driving the pressure plate to rise and fall.

[0009] In a preferred embodiment of this utility model, a second telescopic cylinder for driving the lifting seat to rise and fall is provided on the pressure plate.

[0010] In a preferred embodiment of the present invention, the first blade sleeve is provided with a first mounting groove corresponding to the first transverse punching blade.

[0016] The beneficial effects of this utility model are as follows: The injection molding part terminal pressing and cutting device disclosed in this utility model allows the material strip to move forward intermittently in the material strip guide groove under the action of other stretching equipment. When the material strip is paused, the pressure plate is used to press and solidify the terminals of two adjacent injection molding parts. Then, the lifting seat drives the first and second cutting sleeves to descend. The first transverse cutting blade, the second transverse cutting blade, the first longitudinal cutting blade, and the second longitudinal cutting blade are used to simultaneously cut the first material bridge and the second material bridge at intervals, thereby improving production efficiency.

[0027] like Figure 3 As shown, the first transverse cutting blade 16 is vertically arranged in the first blade holder 5 and corresponds to the odd-numbered first material bridge. In this embodiment, the first blade holder 5 is vertically provided with a first mounting groove 13 corresponding to the first transverse cutting blade 16, which facilitates assembly.
