Detailed ways

Refer to Fig. 1 for the overall system of the automatic lead mold making device of the present invention, including a mold casing system 1, a molten lead casting system 3, a cooling system 4, a demoulding system 5, a mold demoulding system 6 and a mold locking system 2. Among them, the die set system 1 places the positive mold of the conformable lead mold, and the action objects of other systems are the die set system 1 . The molten lead casting system 3 is responsible for the casting process, that is, converting solid lead into liquid lead and casting it into the mold casing system 1 to a predetermined height. The cooling system 4 is responsible for the cooling process, that is, the accelerated molten lead is cooled and formed into a lead mold in the mold casing system 1 . The demoulding system 5 is responsible for the demoulding process, that is, the lead mold that has been cooled and formed is separated from the die casing system 1 . The mold ejection system 6 is responsible for the mold ejection process, that is, the forming lead mold that is separated from the mold casing system 1 is placed in a predetermined position (or in a predetermined container) for people to take out. The mold clamping system 2 is responsible for lifting or lowering the height of the mold casing system 1 according to the needs in each process.

Please refer to Fig. 2 for a schematic structural diagram of a specific embodiment of the automatic lead mold making device of the present invention. Wherein, the mold cover system includes a lead-making mold cover 11 and a pallet 12 . The lead mold cover 11 is used to place the positive mold of the conformable lead mold, and the positive mold is usually a conformal foam. Lead-making mold cover 11 is hollow structure, and bottom surface does not exist, and protruding structure 111 is arranged on the side. The lead mold cover 11 is placed on the pallet 12 .

In the embodiment shown in FIG. 2 , the lead melting casting system includes a lead melting furnace 31 , a casting pipe 32 , a casting control valve 33 and a liquid level sensor (not shown). Wherein, the lead-melting furnace 31 melts solid lead into liquid lead, and the molten lead flows into the lead-making mold cover 11 through the casting pipe 32 and the casting control valve 33 for casting. The liquid level sensor monitors the molten lead liquid level height in the lead-making mold cover 11 in the casting process. When the liquid level sensor monitors that the molten lead liquid level in the lead-making mold cover 11 reaches a predetermined height, it sends a signal to the casting control valve 33, and the casting control valve 33 closes after receiving the signal, thereby stopping the casting process.

In the described lead-melting casting system, the casting control valve 33 and the liquid level sensor 34 are located above the lead-making mold sleeve 11 , the casting pipe 32 is located above the casting control valve 33 , and the lead-melting furnace 31 is located above the casting pipe 32 .

In the embodiment shown in Fig. 2, the cooling system includes a draft device (not shown), an air duct 41 and a temperature sensor (not shown), the temperature sensor monitors the temperature in the lead-making mold cover 11, and provides a signal to control the draft device opening and closing. The temperature sensor monitors the temperature in the lead-making mold cover 11, and when it is monitored that the temperature drops to a predetermined value, the temperature sensor sends a signal, and the ventilation equipment stops exhausting. The main function of the cooling system is to quickly extract the hot air around the lead mold container 11 out of the room along the air duct 41, thereby accelerating the cooling and forming speed of the lead mold in the lead mold cover 11.

In the embodiment shown in FIG. 2 , the demoulding system includes a demoulding motor 51 , a demoulding push rod 52 and a hook 53 . Wherein, the demoulding push rod 52 and the suspension hook 53 are driven by the demoulding motor 51 . After the lead mold is cooled and formed in the lead-making mold cover 11, the suspension hook 53 catches the side protrusion 111 of the lead-making mold cover 11 and fixes it. Because the lead-making mold cover 11 is a hollow structure, the bottom does not exist, so the demoulding push rod 52 moves up and down, knocks the forming lead mold in the lead-making mold cover, and the forming lead mold can be removed from the lead-making mold cover from top to bottom Launched in 11. The forming lead mold falls on the pallet 12, and the demoulding is completed.

In the described demoulding system, the demoulding push rod 52 and the suspension hook 53 are all located above the lead-making mold sleeve 11 .

In the embodiment shown in FIG. 2 , the ejection system includes an ejection motor 61 and an ejection push rod 62 . After the lead mold falls on the tray 12, the ejection motor 61 drives the ejection push rod 62 to move horizontally, pushing the tray 12 together with the formed lead mold thereon to a predetermined position or a predetermined container.

In the embodiment shown in FIG. 2 , the mold clamping system includes a mold clamping motor 21 , a lift shaft 22 , a lift platform 23 and a guide shaft 24 . Wherein, the clamping motor 21 drives the lifting shaft 22 to rotate. Lifting shaft 22 is generally a screw structure, and a lifting platform 23 is installed on the top of lifting shaft 22, and the forward or reverse rotation of lifting shaft 22 can drive lifting platform 23 to rise or fall. There are one or more guide shafts 24, and the rise or fall of the lifting platform 23 takes the guide shaft 24 as the vertical axis. Pallet 12 is placed on the lifting platform 23, and lead-making mold cover 11 is placed on the pallet 12, and when there is no other external force, lead-making mold cover 11 and pallet 12 all follow lifting platform 23 to rise or fall together.

The mold clamping system drives the tray 12 and the lead-making mold cover 11 thereon to rise or fall according to the requirements of each operation during casting, demoulding and demoulding operations. For example, in the casting process, the clamping system drives the lead-making mold cover 11 to rise, so that the lead-making mold cover 11 and the casting control valve 33 are in the closest state. In the demoulding process, the clamping system first drives the lead-making mold cover 11 to rise, and the hook 53 catches the side protrusion 111 of the lead-making mold cover 11 . Then the clamping system drives pallet 12 to descend again, and now lead-making mold cover 11 is fixed in mid-air by suspension hook 53, does not descend with pallet 12. The demoulding push rod 33 moves up and down, and the lead mold made is released from the lead mold cover 11 and falls on the pallet 12. In the mold ejection process, the mold clamping system drives the tray 12 to be located on the same level as the ejection push rod 62, and the ejection push rod 62 pushes the tray 12 horizontally, that is, pushes the tray 12 and the forming lead mold on it to a predetermined position or in the intended container.

The whole set of automatic lead mold making device shown in Fig. 1 is fixed on a mobile base, and the mobile base includes one or more wheels, so as to facilitate the overall movement.
