One end of the first elastic member 16 abuts against the lower mold bearing assembly 11, and the other end of the first elastic member 16 abuts against the first lifting member 15, so that the lower mold plate insert 12 is floatingly arranged in the receiving groove 111. In this way, by providing the first elastic member 16, the lower mold plate insert 12 can be separated from the bottom of the receiving groove 111 when the mold is opened. Specifically, the first lifting member 15 is T-shaped. One end of the first lifting member 15 passes through the bottom of the receiving groove 111 and the lower pad 115 insert and is movably clamped at the lower pad 115 insert. The first elastic member 16 is located in the lower mold base 114. The first elastic member 16 is a spring.

Specifically, the second heat insulating member 133 is a mica sheet.

[0081] The lower mold 10 also includes a second lifting member 17 and a second elastic member 18. One end of the second lifting member 17 passes through the bottom of the accommodating groove 111 and is movably arranged in the lower mold bearing assembly 11.

One end of the second elastic member 18 abuts the lower mold bearing assembly 11, and the other end of the second elastic member 18 abuts the second lifting member 17, so that the upper stripper plate insert 13 is floatingly arranged on the side of the lower mold plate insert 12 away from the lower mold bearing assembly 11. In this way, by setting the second elastic member 18, the upper stripper plate insert 13 can be separated from the lower mold plate insert 12 when the mold is opened. Specifically, the second lifting member 17 is T-shaped, one end of the second lifting member 17 passes through the bottom of the accommodating groove 111 and the inlet of the lower pad 115 and is movably clamped at the inlet of the lower pad 115, and the second elastic member 18 is located in the lower mold base 114. The second elastic member 18 is a spring.

[0082] The heating assembly 14 includes a heating coil 141, a heating machine 142 and a thermocouple 143.

The thermocouple 143 is disposed in the lower mold insert 12 and is electrically connected to the heating machine 142, and is used to sense the heating temperature of the lower mold insert 12. In this way, the heating machine 142 heats the lower mold insert 12 through the heating coil 141, and senses the heating temperature of the lower mold insert 12 through the thermocouple 143, so that the heating temperature of the lower mold insert 12 can be controlled to be within a preset value, thereby ensuring the heating effect on the material strip 200. Specifically, the heating machine 142 is disposed on one side of the lower mold bearing assembly 11, and the heating coil 141 is disposed between the second mold insert 122 and the upper stripper plate insert 13 and connected to the side of the first mold insert 121.

In this way, the material strip 200 on the lower template inlet 12 can be kept warm when the mold 100 is closed to ensure the heating temperature. Specifically, the two heat insulating members 19a are respectively located on opposite sides of the first template inlet 121. The heat insulating member 19a is a mica sheet.

[0085] Please continue to see Figure 2 The upper die pressing die assembly 21 includes an upper die 20 seat 211, an upper pad 212, an upper clamping plate 213, an upper stripper plate backing plate 214 and an upper stripper plate 215 which are stacked in sequence. A molding groove 2151 is provided on the side of the upper stripper plate 215 away from the upper stripper plate backing plate 214. The molding groove 2151 is adapted to the shape of the upper stripper plate insert 13. The molding part 22 is arranged in the molding groove 2151 and one end of the molding groove 2151 is connected to the groove bottom of the molding groove 2151. Specifically, the molding groove 2151 is a through groove, and the groove bottom of the molding groove 2151 is formed on the side of the upper stripper plate backing plate 214 close to the upper stripper plate 215.

[0086] The implementation process of the mold 100 of the embodiment of the present application is:

[0087] The heater 142 generates a high frequency current through the heating coil 141 to heat the lower mold insert 12;

[0088] After the thermocouple 143 senses that the temperature of the lower template inlet 12 reaches a preset value, the material strip 200 on the material rack is flattened by a flattening machine (not shown) and then transported to between the lower template inlet 12 and the upper stripper plate inlet 13 of the mold 100 through a feeder and carried on the lower template inlet 12;

[0089] The upper mold pressing die assembly 21 is moved toward the lower mold supporting assembly 11. During the movement, the molding groove 2151 will be sleeved on the upper stripper plate insert 13 and the bottom of the molding groove 2151 will press against the upper stripper plate insert 13 to move toward the lower template insert 12, so that the lower template insert 12 elastically presses against the bottom of the accommodating groove 111 and the upper stripper plate insert 13 elastically presses against the lower template insert 12, so that the molded part 22 passes through the upper stripper plate insert 13 and presses the heated material strip 200 on the lower template insert 12 to form the workpiece.

[0090] It can be understood that before forming the workpiece, the upper die assembly 21 punches the guide holes and side edges of the material strip 200 on the lower die insert 12; after forming the workpiece, the material strip 200 is continuously conveyed until the blanking is completed.

[0091] The mold 100 described above, when the upper mold 20 and the lower mold 10 are molded together, the heating component 14 is first used to heat the material strip 200 on the lower mold plate insert 12, and then the upper mold pressing mold component 21 is moved toward the lower mold bearing component 11 to abut the upper stripper plate insert 13 to move toward the lower mold plate insert 12 and make the lower mold plate insert 12 abut the bottom of the accommodating groove 111 and the upper stripper plate insert 13 abut the lower mold plate insert 12, so that the molded part 22 passes through the upper stripper plate insert 13 and molds the heating stripper plate on the lower mold plate insert 12. The heated material strip 200 is used to form workpieces. Since the lower template insert 12 is floatingly arranged in the accommodating groove 111, and the upper stripper plate insert 13 is floatingly arranged on the side of the lower template insert 12 away from the lower mold supporting component 11, the upper stripper plate insert 13 will not damage the workpiece during molding; and the material strip 200 can pass between the lower template insert 12 and the upper stripper plate insert 13 and be carried on the lower template insert 12, and the material strip 200 can be moved to form multiple workpieces on the material strip 200 in sequence, and the production efficiency is relatively high.

[0092] Furthermore, TC4 titanium alloy must be heated during molding, otherwise cracking will occur. For mobile phone internal components, generally thin material precision parts, continuous molds are used for production. TC4 titanium alloy must be used in continuous molds for mobile phone internal components and the material strip 200 must be heated before molding. Directly heating the material strip 200 in the continuous mold will cause the material strip 200 to deform and cannot be produced. Therefore, the present application designs a lower template insert 12 and an upper stripper plate insert 13 in the portion of the material strip 200 that needs to be heated, and the lower template insert 12 is heated by high-frequency heating. The lower template insert 12 is floating and is placed in the lower mold bearing assembly 11. The material strip 200 passes between the lower template insert 12 and the upper stripper plate insert 13. When the mold is closed, the material strip 200 is pressed to achieve heating of the material strip 200. In this way, continuous production of TC4 titanium alloy can be achieved with high precision and low cost.

[0093] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
