Description

Technical Field

[0001] The utility model relates to the technical field of drilling fixtures, in particular to a plastic box drilling fixture. Background Art

[0002] Electronic products or parts need to be packaged after production is completed. The common packaging method for transportation and circulation is plastic box packaging.

[0003] Plastic boxes are permanently durable, moisture-proof, waterproof and highly tough, which ensure the safety of products during transportation. In addition, due to the light weight and good mechanical properties of plastic boxes, they can effectively reduce the transportation weight and facilitate transportation. Furthermore, plastic boxes have excellent physical properties, such as impact resistance and kneading resistance, and stable chemical properties, such as high temperature resistance, low temperature resistance, water resistance, and oil resistance. Finally, blister packaging also meets the requirements of environmentally friendly green packaging and can increase product sales because the packaged products are transparent and visible, and have beautiful appearance.

[0004] When packaging in a plastic box, a plastic cover is usually added on the upper side. The plastic cover needs to be snapped together with the plastic box. A common method is to punch holes on the edge of the plastic box to facilitate snapping with the plastic cover. Since the plastic box has good ductility, the punched part is easily pulled when punching, which can easily lead to the plastic box being scrapped and causing waste. Utility Model Content

[0028] The handle 23 can be used to conveniently take out the lower mold 2 and replace the punching fixture of the corresponding plastic box, which is highly practical. At the same time, the upper and lower molds cooperate to press down and fix the plastic box to be punched, so that when punching, the punching position is reduced from being pulled, thereby ensuring the quality of the punching and reducing waste. At the same time, through the setting of the jacking structure 5, the punched plastic box can be ejected, which is convenient for the staff to take and improve work efficiency.

[0029] In another embodiment, see Figures 1 to 3 The jacking structure 5 includes a laterally arranged support plate 51, and the support seat 1 is provided with a first movable cavity 12 corresponding to the support plate 51. Both sides of the support plate 51 are slidably connected with the inner side walls of the first movable cavity 12. The side walls of the first movable cavity 12 are longitudinally provided with slide grooves 13 corresponding to the left and right sides of the support plate 51, and the left and right sides of the support plate 51 are provided with matching sliders 53 corresponding to the slide grooves 13, so that the support plate 51 can be kept in a horizontal state when moving, so that it can perform normal jacking work. A push rod 52 is vertically provided on the upper side of the support plate 51, and the push rod 52 passes through the support seat 1 upward and is slidably connected thereto. A second through hole 22 is provided at the bottom of the lower mold 2 corresponding to the push rod 52, and the push rod 52 passes through the second through hole 22 and extends to be flush with the bottom side of the limiting groove 21. There is still a driving component 6 in the first movable cavity 12, and the driving component 6 is drivingly connected to the support plate 51;

[0030] In this embodiment, the driving assembly 6 includes a vertically arranged threaded rod 61, which passes through the middle of the support plate 51 and is threadedly connected thereto, and both ends of the threaded rod 61 are inserted into the upper and lower side walls of the first movable cavity 12 and are rotatably connected thereto, and a first bevel gear 62 is fixedly arranged at one end of the threaded rod 61 located at the lower side of the support plate 51, and a rotating rod 63 is horizontally arranged at a side of the support seat 1 corresponding to the first bevel gear 62, and the rotating rod 63 passes through the support seat 1 and extends to the first bevel gear 62, and a second bevel gear 64 meshing with the first bevel gear 62 is fixedly arranged at the end corresponding to the first bevel gear 62, and a knob 65 is fixedly arranged at one end of the rotating rod 63 located outside the support seat;

[0031] After the punching is completed, the plastic box may remain in the limiting groove 21, making it inconvenient to take out. At this time, the knob 65 can be turned to rotate the rotating rod 63, thereby driving the first bevel gear 62 to rotate, so that the second bevel gear 64 meshing with it rotates, thereby driving the threaded rod 61 to rotate, so that the support plate 51 threadedly connected to it moves upward, thereby pushing the plastic box in the limiting groove 21 out, making it easier for the staff to take it out and improving work efficiency.

[0032] In another embodiment, see Figures 1 to 3 , an insertion rod 42 is vertically arranged on the lower side of the mounting plate 4 corresponding to the top of the upper mold 3, and the insertion rod 42 extends downward to the inside of the upper mold 3, and a second movable cavity 33 is opened in the upper mold 3 corresponding to the insertion rod 42, and a limit block 43 is arranged at one end of the insertion rod 42 located in the second movable cavity 33, and a spring 34 is still arranged in the second movable cavity 33, and the spring 34 is located at the lower side of the limit block 43;

[0033] First, select upper and lower molds corresponding to the shape of the plastic box, place the bottom of the lower mold 2 in the positioning groove 11 for positioning, install the upper side of the upper mold 3 on the external hydraulic equipment, and then lift the upper mold 3 through the external hydraulic equipment, place the plastic box to be punched in the limit groove 21, limit it to ensure its punching accuracy, and then drive the upper mold 3 down through the external hydraulic equipment. While descending, the limit pressure block 31 under the upper mold 3 first contacts the plastic box to be punched, and presses down and fixes the plastic box under the elastic force of the spring 34. While compressing the spring 34, the punching head 41 passes through the first through hole 32 to punch the plastic box. Due to the downward pressure and fixation of the limit pressure block 31, the phenomenon of pulling at the punching point is reduced during punching, thereby ensuring the punching quality and reducing waste.
