A lower die 5 is arranged in the center of the top of the water storage base 1. The rear side of the lower die 5 is connected to the feed pipe 6. A two-way water inlet 10 is provided at the rear side of the upper inner part of the water storage base 1 to connect the external water source and the water storage base 1 The cavity is used to fill cooling water. The two-way water inlet 10 is connected to the cavity of the water storage base 1, and the two-way water inlet 10 is located at the inner and lower part of the cavity. The cavity of the water storage base 1 is connected with a water pipe 7 for conducting cold and accelerating the cooling speed. The upper part of the water pipe 7 is arranged around the inside of the lower pressure mold 5, and the output end of the rear lower part of the water pipe 7 extends from the lower pressure membrane and passes through the upper part of the water storage base 1 to enter the cavity.

A refrigerator 9 is provided on the side of the water pipe 7 adjacent to the water pump 8 to cool the water extracted by the water pump 8 to form a circulating cooling system. A flow plug 11 is connected to the rear end of the two-way water inlet 10 for controlling the flow of water in and out of the cavity of the water storage base 1. A liquid level sensor 12 is provided on the lower side of the upper pressure membrane to detect the amount of raw materials and ensure that an appropriate amount of raw materials are injected.

[0024] like Figure 1-Figure 2 As shown, a controller 13 is also included. The controller 13 is arranged at the center of the top of the upper die 3. The electric cylinder 4, the water pump 8, the refrigerator 9 and the liquid level sensor 12 are all electrically connected to the controller 13.

[0025] like Figure 1-Figure 2 As shown, an alarm Ⅰ14 is also included. The alarm Ⅰ14 is set on the rear side of the top of the upper die 3. The alarm Ⅰ14 is electrically connected to the liquid level sensor 12. The alarm Ⅰ14 can sound an alarm when the raw material amount reaches the set value, prompting the operator to close the discharge pipe.

[0026] like Figure 1 and Figure 6-Figure 7As shown, it also includes an ejection mechanism 15. The ejection mechanism 15 is commonly provided between the water storage base 1 and the lower die 5. The ejection mechanism 15 is respectively located on both sides of the water storage base 1 and the lower die 5. The ejection mechanism 15 can automatically eject the formed urn storage rack from the lower die 5 after the die casting is completed, reducing the need for manual intervention and improving production efficiency and safety. The ejection mechanism 15 includes: a lifting plate 150, a protective frame 151, a connecting rod 152, a gear 153, a rotating rod 154, a torsion spring 155, and a folding rod. 156, spring 157 and rack 158, a lifting plate 150 is slidingly provided at the bottom of the lower die 5, and there are two protective frames 151, which are respectively located between the water storage base 1 and the two sides of the lower die 5. The protective frames 151 are used to shield and protect the components contained in the ejection mechanism 15 to ensure the stability and durability of the mechanism. Connecting rods 152 are symmetrically provided on both sides of the bottom of the lifting plate 150. The connecting rods 152 on both sides extend outward and are in contact with both sides of the water storage base 1. Gears 1 are provided on both sides of the upper part of the water storage base 1 to rotate. 53, and the gear 153 is located below the extension of the connecting rod 152, and a rotating rod 154 is provided on each of the two side gears 153. The rotating rods 154 on both sides are in rotational contact with the end surface of the water storage base 1, and the front of the rotating rods 154 on both sides are in rotational contact with the extension of the upper connecting rod 152. The rotating connection between the inner side of the gear 153 on both sides and the water storage base 1 is provided with a torsion spring 155. A folding rod 156 is slidably provided on the two front guide rods 2, and a spring 157 is provided between the folding rods 156 on both sides and the lower part of the guide rod 2. , spring 157 and torsion spring 155 ensure that the folding rod 156 and gear 153 can be smoothly reset to prepare for the next ejection operation. The lower ends of the folding rods 156 on both sides are close to the rotating rod below. The lower ends of the folding rods 156 on both sides are provided with racks 158. The racks 158 on both sides are engaged with the gear 153 below. Through the engagement of the gear 153 and the rack 158, the vertical movement of the upper die 3 is converted into horizontal movement, and then the lifting plate 150 is driven to rise through the rotation of the rotating rod 154 to realize the ejection of the finished product.

[0027] like Figure 1-Figure 2 As shown, a monitor 16 is also included. The monitor 16 is set on the left front side of the lower die 5 to monitor the temperature inside the lower die 5 to ensure safe removal of the finished product.

[0028] like Figure 1 As shown, an alarm II 161 is also included. An alarm II 161 is provided on one side of the top of the upper die 3 adjacent to the alarm I 14.

[0029] During use, the electric cylinder 4 is first pre-activated through the controller 13, so that the piston rod of the electric cylinder 4 drives the upper die 3 to descend and approach the upper end surface of the lower die 5. After completion, the electric cylinder 4 is controlled to slowly stop its operation, and then the hot melt machine discharge pipe is connected to the feed pipe 6. The hot melt raw material for the die-cast urn heated by the hot melt machine will be fed from the hot melt machine discharge pipe to the lifting plate 150 at the bottom of the lower die 5. As the amount of raw material injected increases, the liquid level sensor 12 located above the upper die 3 will sense and detect the amount of raw material. When the specified amount of raw material is reached, the liquid level sensor 12 will transmit a signal to the alarm I 14 to warn the operator, so that the operator can close the output port of the discharge pipe in time to prevent excessive raw material from affecting the die-casting effect.

[0030] At this time, the raw material injection operation has been completed and the raw material can be die-casted. The electric cylinder 4 needs to be controlled to operate, driving the upper die 3 to descend and cover the upper end of the lower die 5. When the upper die 3 covers the lower die 5 and its bottom cavity contacts the raw material, the die-casting process has gradually been formed. Immediately afterwards, as the electric cylinder 4 covers the lower die 3, the two are sealed. At this time, the downward pressure generated by the descending upper die 3 completes the die-casting of the raw material. During this process, the lower end of the upper die 3 will contact the upper end surfaces of the folding rods 156 on both sides and push them forward, so that the folding rods 156 slide down along the guide rod 2 and squeeze the spring 157 below. The spring 157 is deformed and compressed. As the folding rod 156 slides down, the rack 158 at its bottom also moves and meshes with the gear 153, causing the gear 153 to rotate and drive the rotating rod 154 to rotate, and the torsion spring 155 will also be driven by the gear 153 to twist and tighten.

[0031] In order to ensure the molding effect of the urn storage rack, it is necessary to quench it in time after die-casting. First, remove the flow blocking plug 11 from the two-way water inlet 10 and connect the water pipe to the outside, so that water enters the cavity of the water storage base 1 through the two-way water inlet 10. After a certain period of time, when the cavity of the water storage base 1 is filled with water, stop delivering water, and start the water pump 8 and the refrigerator 9. The water in the cavity will be pumped into the inlet end of the water pipe 7 by the water pump 8, and then cooled by the refrigerator 9. After the cooling is completed by the refrigerator 9, it will continue to be transported to the water pipe 7, thereby cooling the lower die 5, and The refrigerated water will circulate in the cavity and the water pipe 7, forming a circulating refrigeration, which makes the cooling speed of the lower die 5 as a whole faster, and then quenches the die-cast raw materials in the lower die 5. After a while, in order to avoid scalding the operator, the monitor 16 on the front side of the lower die 5 can monitor the temperature of the cavity of the lower die 5 in real time. When the temperature is suitable for taking out the formed urn storage rack, the monitor 16 will transmit a signal to the alarm II 161 to prompt the operator to take out the formed urn storage rack. The quenching process is completed.

[0032] Then, the formed urn storage rack needs to be taken out. In order to ensure that the formed urn storage rack is not damaged during the removal process, the electric rod can be controlled to drive the upper pressing mold 3 to rise, so that the upper pressing mold 3 is no longer in the state of pushing the folding rod 156, and the spring 157 under the folding rod 156 will no longer be stressed and will be restored and stretched by the self-expansion force, and drive the folding rod 156 to slide up and move the rack 158 upward, so that the rack 158 is engaged with the gear 153 again, and with the rotation force, the torsion spring 155 will no longer be subjected to the rotation. The torque of the rotation, and the loosening force of the gear 153 in an instant, drive the gear 153 to rotate rapidly, the gear 153 will drive the rotating rod 154 to rotate, and under the action of the torsion spring 155, the rotating rod 154 will eventually contact the upper connecting rod 152 and lift it up. When the rotating rods 154 on both sides rotate and lift the connecting rod 152, the lifting plates 150 on top of the two will also be driven to lift upward, so that the molding material on the lifting plates 150 can be driven up synchronously, and the molding material can be removed smoothly at this time.
