Description

Technical Field

[0001] The utility model belongs to the technical field of notebook shell production, and particularly relates to a D-shell arc-shaped back-extrusion die for a notebook. Background Art

[0002] Notebooks, also known as "portable computers, handheld computers, PDAs or laptops", are the bottom shell of a notebook computer, which is the bottom shell of the notebook computer and the shell accessory that contacts the desktop. In order to enhance the slimness of the notebook computer, a curved shape is usually designed around the D shell, so that the thickness of the notebook computer gradually decreases from the inside to the outside. Whether the curved shape of the D shell meets the design 3D curvature requirements is very important for the assembly quality of the entire notebook computer.

[0003] Existing notebook D shells are mostly made of plastic materials or aluminum alloy materials. Plastic D shells generally use PC+ABS materials and are formed by injection molds. Aluminum alloy D shells generally use Al5052 aluminum alloy. In the prior art, aluminum alloy notebook shells, including D shells, are mainly made by stamping. For example, on July 16, 2022, the applicant Hefei Ankefa Precision Mold Co., Ltd. designed a "Stamping Mold for Laptop Shell", and on November 22, 2022, the applicant Guangde Zhuchang Electronic Technology Co., Ltd. designed a "Business Laptop Shell Extrusion Molding Device", etc. The design ideas are similar, but this type of mold / device can only generate a notebook shell with a vertical corner. In the arc shaping of the shell, some companies use a mold with an arc for stamping, such as the mold involved in CN205833980U. There is also a problem after this type of mold processing. The arc shaping structure of the shell is unstable and prone to deformation. In view of this problem, the applicant specially designed this invention. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] like Figure 1-2 As shown, the utility model relates to a notebook D shell arc shape back extrusion mold, comprising an upper template 1 and a lower template 2 for extruding the notebook D shell; the end of the lower template and the end of the upper template have a curvature structure that together forms the notebook D shell; the outer side of the lower template is provided with a back extrusion mechanism for extruding the curved side edge structure of the notebook D shell, and the side edges of the curved structure are solidified by extrusion of the back extrusion mechanism.

[0021] As a technical improvement, an upper die pad 3 is arranged above the upper die plate, and the upper die pad is connected to the stamping drive mechanism.

[0022] As a technical improvement, a lower template pad 6, a lower stripping plate 7 and a lower pad 13 are sequentially arranged below the lower template, and the length of the lower stripping plate is greater than the lower template pad.

[0023] Furthermore, the bottom surface of the lower template has an arc-shaped concave surface 21 matching the arc-shaped 3D of the D shell.

[0024] Furthermore, the top surface of the upper template is provided with an arc-shaped convex surface 101 matching the arc-shaped 3D of the D shell, and the upper template and the lower membrane plate are used to clamp the D shell of the notebook 101.

[0025] As a technical improvement, the back-squeezing mechanism includes a plunger 10, a slider seat 9, a slider seat 5 and a back-squeezing block 4; the back-squeezing block is arranged on the slider seat, the slider seat is arranged on the top surface of the lower stripping plate and is adjacent to the side wall of the lower template pad, the slider seat top surface has an inclined surface 91, and the bottom surface of the slider is slidably connected to the inclined surface; the inclined upper end of the inclined surface points to the outer edge of the lower template; wherein a perforation is arranged at the edge position of the overlapping position of the lower stripping plate and the lower pad; the plunger passes through the lower stripping plate and the lower pad through the perforation and forms a sliding relationship with them, and the upper end of the plunger has an inclined side wall 110 near the slider as a product back-squeezing position, and a lower clamping plate 8 is arranged at the lower end of the plunger, and a plurality of nitrogen springs 12 are arranged between the lower clamping plate and the lower pad. wherein the inclined side wall at the upper end of the plunger is adjacent to the outer wall of the slider, and when the lower stripping plate moves downward, the upper end of the plunger moves upward relative to the lower pad and the lower stripping plate, and the plunger pushes the slider seat through the inclined side wall.

[0026] As a technical improvement, the insert is fixed to the lower clamping plate 8 by means of screws 11 .

[0027] As a technical improvement, the outer wall of the back-extrusion block near the lower template has a convex portion 41, the length of which is equivalent to the length of the back-extrusion block; the convex portion can contact the end face of the D-shell arc shape. A groove 51 is set on the slide seat, and a convex ridge 42 matching the groove is set on the bottom surface of the back-extrusion block. The convex ridge is fixed to the slide seat through the groove, for example, by using a screw set on the back-extrusion block to lock it on the slide.

[0028] During processing, the D-shell of the notebook that has been initially formed into an arc is placed on the lower template, and then the upper template pad is moved downward by the drive mechanism, and the lower template is clamped and positioned by the upper template. At this time, the arc concave surface of the upper template and the arc convex surface of the lower template completely match the 3D arc shape of the notebook D-shell, such as Figure 3 As shown, when the pressure continues to be pressed, the insert knife moves upward relative to the lower pad and the lower release plate. In addition, the end face of the arc shape of the notebook D shell is squeezed by the convex part. This processing method forms a stable arc shape without deformation. It should be noted that the insert knife has a height travel of about 1mm, so when the nitrogen spring is restored, the insert knife will not retreat into the lower release plate, that is, the slider seat is always on the inclined surface of the slider seat and will not fall off.
