Description

Technical Field

[0001] This invention relates to the field of container corner piece casting and processing equipment, specifically to a forming mold for container corner piece processing, which is mainly used for casting and forming container corner pieces. Background Technology

[0002] Container corner fittings, also known as container corners or lifting corners, are mainly used at the corners of containers and play a crucial role in the lifting, handling, securing, stacking, and fastening of containers.

[0003] Currently, container corner fittings are generally manufactured using coated sand casting. Existing coated sand casting molds for container corner fittings typically consist of an iron shell and a mold body embedded within the iron shell by a layer of steel shot. The mold body comprises an upper sand shell and a lower sand shell with a forming cavity, which are then joined together. Molten steel is poured through a sprue located on the upper sand shell to cast the workpiece. The steel shot layer within the iron shell provides support for the upper and lower sand shells and facilitates rapid heat dissipation, ensuring the casting effect of the container corner fitting. After the workpiece cools and the sand is removed, it is then cut and separated using appropriate cutting equipment. Because the steel shot layer of the coated sand casting mold used for container corner fitting processing needs to provide a certain support for the mold body and play a role in heat transfer and dissipation, the filling of the steel shot layer needs to be compact and the gap ratio needs to be reduced. As a result, it is basically impossible to add new steel shot to the steel shot layer after it is heated. And the heat dissipation efficiency of the steel shot is relatively low when it is cooled naturally. Consequently, it is difficult to effectively improve the overall heat dissipation effect of the steel shot layer.

[0004] Therefore, the research objective of this invention is to design a forming mold for container corner parts that can significantly improve heat dissipation efficiency locally, thereby effectively improving the heat dissipation effect of the steel shot layer and thus effectively assisting in improving the casting and forming effect of the workpiece, without affecting the workpiece casting process, that is, without affecting the support and heat dissipation of the steel shot layer for the mold body. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a forming mold for processing container corner fittings, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A forming mold for processing container corner fittings, comprising: The mold body is embedded in a corresponding iron shell through a corresponding steel shot layer. The mold body includes an upper sand shell and a lower sand shell that are closed to each other. A corresponding molding cavity is provided between the closed upper sand shell and the lower sand shell. A pouring port that communicates with the molding cavity is provided on the upper sand shell. The feed end of the pouring port extends to the upper part of the steel shot layer. The cooling acceleration assembly includes a heat exchange container longitudinally embedded in a steel shot layer on the outside of the mold body at intervals. The heat exchange container is divided into an upper cavity and a lower cavity by corresponding partitions. The partitions are provided with corresponding flow holes, and corresponding first hot melt adhesive blocks are sealed and filled in the flow holes. The upper part of the heat exchange container is provided with corresponding material guide holes and vent holes. Corresponding material guide pipes are detachably installed at the material guide holes. The top of the material guide pipes extends to the upper side of the steel shot layer and is connected to a corresponding collection hopper. The bottom of the material guide pipes is sealed and filled with corresponding second hot melt adhesive blocks. The upper cavity is filled with corresponding cooling water, and the lower cavity is filled with a number of corresponding heat-absorbing metal balls. The collection hopper and the material guide pipes are filled with a number of corresponding spare metal balls.

[0007] Molten steel is poured into the casting port of the mold body through an external ladle, and then enters the forming cavity through the casting port for workpiece casting. As the temperature of the steel shot layer and the heat exchange container rises, the cooling water stored in the upper cavity and the heat-absorbing metal balls stored in the lower cavity continue to absorb heat. After the first hot melt adhesive block is melted through, the cooling water stored in the upper cavity flows into the lower cavity and comes into contact with the heated heat-absorbing metal balls. The cooling water after vaporization and phase change is discharged through the vent hole. After the second hot melt adhesive block is melted through, the spare metal balls stored in the collecting hopper and the guide pipe enter the upper cavity through the guide hole.

[0008] A corresponding filter screen is detachably installed at the vent hole. The feed tube and the feed hole, as well as the filter screen and the vent hole, are detachably connected by threaded connection.

[0009] The heat-absorbing metal ball and the spare metal ball are both made of aluminum. The spare metal ball located on the hopper is equipped with a corresponding high-temperature resistant magnetic attractor. After the spare metal ball enters the upper cavity, the high-temperature resistant magnetic attractor is attracted and fixed to the guide hole of the hopper.

[0010] The heat exchange container of the cooling acceleration component has a cross-section that is either right-angled or arc-shaped.

[0011] The outer side wall of the heat exchange container is fixed with corresponding connecting rods, which are then fixedly installed onto the iron shell by corresponding locking bolts.

[0012] The molding cavities are distributed around the upper and lower sand shells, and the molding cavities are respectively connected to the inlet end of the pouring port through corresponding material guiding channels.

[0013] The upper sand shell is provided with a feeding assembly, which includes a casting feeding cavity located on the upper side of the middle part of the upper sand shell. The casting feeding cavity is connected to the material guiding channel, and a corresponding sand rod is fixedly connected downward at the top center of the casting feeding cavity.

[0014] The top of the upper sand shell is integrally formed and has several corresponding reinforcing ribs that are inclined at the top of the upper sand shell.

[0015] The bottom of the lower sand shell is integrally formed and has several corresponding pads arranged downwards.

[0016] Advantages of this invention: 1) Based on the existing mold body, steel shot layer, and iron shell, the present invention further adds a cooling acceleration component, which includes a heat exchange container embedded longitudinally in the steel shot layer outside the mold body at intervals. The heat exchange container is divided into an upper cavity and a lower cavity by a corresponding partition. The partition is provided with a flow hole, and the flow hole is sealed with a first hot melt adhesive block. The upper part of the heat exchange container is provided with a corresponding material guide hole and a vent hole. A corresponding material guide pipe is detachably installed at the material guide hole. The top of the material guide pipe extends to the upper side of the steel shot layer and is connected to a corresponding material collection hopper. The bottom of the material guide pipe is sealed with a second hot melt adhesive block. The upper cavity of the heat exchange container is filled with cooling water, and the lower cavity is filled with a number of corresponding heat-absorbing metal balls. The material collection hopper and the material guide pipe are filled with a number of corresponding spare metal balls.

[0017] During the casting process, as the temperature of the steel shot layer and the heat exchange container rises, the cooling water stored in the upper cavity and the heat-absorbing metal balls stored in the lower cavity continuously absorb heat. Some of the cooling water vaporizes and is discharged through the vent at the top of the upper cavity after heating, while the heat-absorbing metal balls absorb a large amount of heat. After the first hot melt adhesive block is melted through, the cooling water stored in the upper cavity is poured into the lower cavity and comes into contact with the heated heat-absorbing metal balls. The vaporized cooling water carries away the large amount of heat energy absorbed by the heat-absorbing metal balls and is further discharged through the vent to enhance the heat absorption capacity of the heat-absorbing metal balls. After the second hot melt adhesive block is melted through, the spare metal balls stored in the hopper and the guide pipe enter the upper cavity through the guide hole to replenish the heat dissipation material (spare metal balls) that has not yet absorbed a large amount of heat in the upper cavity, thereby replacing the vaporized cooling water to rapidly absorb heat in the upper cavity. Thus, without affecting the workpiece casting process, that is, without affecting the support and heat dissipation of the steel shot layer for the mold body, the heat dissipation efficiency of the present invention can be effectively and significantly improved locally, so as to effectively assist in improving the heat dissipation effect of the steel shot layer, and thus effectively assist in improving the casting and forming effect of the workpiece.

[0018] 2) In the initial stage of heat absorption, the cooling water and the heat-absorbing metal ball of this invention are isolated, ensuring that the heat absorption performance of the heat-absorbing metal ball is not affected. The cooling water is discharged through its vaporization phase change to remove a large amount of heat, thus effectively ensuring local heat absorption and dissipation. As the first hot melt adhesive block melts and penetrates, the unvaporized cooling water enters the lower cavity and comes into contact with the heated heat-absorbing metal ball, further removing a large amount of heat during its vaporization phase change. This effectively enhances the local rapid cooling effect of this invention, thereby effectively assisting in improving the heat dissipation effect of the steel shot layer. Most importantly, the cooling water does not come into contact with the steel shot layer or the mold body during the process from heat absorption to vaporization phase change and discharge, thus effectively preventing adverse effects on the casting quality of the workpiece due to the use of the cooling water.

[0019] 3) The heat exchange container of the present invention has a detachable filter screen installed at the vent hole. The detachment and installation of the filter screen facilitates the loading and unloading of the heat-absorbing metal balls and the spare metal balls, as well as the sealing and loading of the first hot melt adhesive block. After the filter screen is installed in place, it can effectively prevent the heat-absorbing metal balls and the spare metal balls from being discharged through the vent hole. At the same time, the present invention also uses aluminum to make the heat-absorbing metal balls and the spare metal balls, and places a corresponding high-temperature resistant magnetic suction component on the top of the spare metal ball located on the hopper. After the spare metal ball enters the upper cavity, the high-temperature resistant magnetic suction component will attract and fix it to the guide hole of the hopper to seal the hopper, thereby effectively preventing the heat-absorbing metal balls and the spare metal balls from being discharged through the guide pipe. To ensure that the heat-absorbing metal balls and spare metal balls can be stably stored in the heat exchange container during the removal of the workpiece after casting and the recycling of steel shot, thereby facilitating the secondary use of the heat-absorbing metal balls and spare metal balls and facilitating the centralized removal of hot melt adhesive adhering to the heat-absorbing metal balls and spare metal balls.

[0020] 4) The upper sand shell of the present invention is provided with a feeding assembly, which includes a casting feeding cavity disposed on the upper side of the middle part of the upper sand shell. The casting feeding cavity is connected to the material guiding channel and a corresponding sand rod is fixedly attached downward at the top center. By intervening with the sand rod, the air permeability of the area where the casting feeding cavity is located is improved, so that the molten steel in the casting feeding cavity can be fed into the forming cavity in a timely manner, thereby reducing the probability of shrinkage cavities forming on the surface of the workpiece.

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-8 A forming mold for processing container corner fittings, comprising: The mold body 1 is embedded in the corresponding iron shell 3 through the corresponding steel shot layer 2. The mold body 1 includes an upper sand shell 101 and a lower sand shell 102 that are closed to each other. A corresponding molding cavity 4 is provided between the closed upper sand shell 101 and the lower sand shell 102. A pouring port 5 that communicates with the molding cavity 4 is provided on the upper sand shell 101. The feed end of the pouring port 5 extends to the upper part of the steel shot layer 2. The cooling acceleration assembly 6 includes a heat exchange container 601 longitudinally embedded in the steel shot layer 2 on the outer side of the mold body 1 at intervals. The heat exchange container 601 is divided into an upper cavity 6011 and a lower cavity 6012 by corresponding partitions 7. The partitions 7 are provided with corresponding flow holes 8, and corresponding first hot melt adhesive blocks 9 are sealed and filled at the flow holes 8. The upper part of the heat exchange container 601 is provided with corresponding material guide holes 10 and vent holes 11. The material guide holes 10 are respectively detachably equipped with… The corresponding feed pipe 602 extends to the upper side of the steel shot layer 2 and is connected to the corresponding collection hopper 603. The bottom of the feed pipe 602 is sealed and filled with the corresponding second hot melt adhesive block 12. The upper cavity 6011 is filled with the corresponding cooling water 604. The lower cavity 6012 is filled with a number of corresponding heat-absorbing metal balls 605. The collection hopper 603 and the feed pipe 602 are respectively filled with a number of corresponding spare metal balls 606.

[0031] Molten steel is poured into the pouring port 5 of the mold body 1 through an external ladle, and then enters the forming cavity 4 through the pouring port 5 for workpiece casting. As the temperature of the steel shot layer 2 and the heat exchange container 601 rises, the cooling water stored in the upper cavity 6011 and the heat-absorbing metal balls 605 stored in the lower cavity 6012 continue to absorb heat. After the first hot melt adhesive block 9 is melted through, the cooling water 604 stored in the upper cavity 6011 is poured into the lower cavity 6012 and comes into contact with the heated heat-absorbing metal balls 605. The cooling water 604 after vaporization phase change is discharged through the vent hole 11. After the second hot melt adhesive block 12 is melted through, the spare metal balls 606 stored in the collecting hopper 603 and the guide pipe 602 enter the upper cavity 6011 through the guide hole 10.

[0032] This invention adds a cooling acceleration component 6 to the existing mold body 1, steel shot layer 2, and iron shell 3. During the casting process, as the temperature of the steel shot layer 2 and the heat exchange container 601 rises, the cooling water 604 stored in the upper cavity 6011 and the heat-absorbing metal balls 605 stored in the lower cavity 6012 continuously absorb heat. Part of the cooling water 604 vaporizes after heating and is discharged through the vent 11 at the top of the upper cavity 6011, while the heat-absorbing metal balls 605 absorb a large amount of heat. After the first hot melt adhesive block 9 is melted through, the cooling water 604 stored in the upper cavity 6011 flows into the lower cavity 6012 and comes into contact with the heated heat-absorbing metal balls 606. After the phase change, the cooling water 604 carries away a large amount of heat energy absorbed by the heat-absorbing metal balls 605 and discharges it further through the vent 11, thereby enhancing the heat absorption capacity of the heat-absorbing metal balls 605. After the second hot melt adhesive block 12 is melted through, the spare metal balls 606 stored in the collecting hopper 603 and the guide pipe 602 enter the upper cavity 6011 through the guide hole 10, so as to replenish the heat dissipation material (spare metal balls 606) that has not yet absorbed a large amount of heat into the upper cavity 6011, thereby replacing the cooling water 604 after the vaporization phase change to rapidly absorb heat in the upper cavity 6011. Thus, without affecting the workpiece casting process, that is, without affecting the support and heat dissipation of the steel shot layer 2 for the mold body 1, the heat dissipation efficiency of the present invention is effectively and significantly improved locally, thereby effectively assisting in improving the heat dissipation effect of the steel shot layer 2, and thus effectively assisting in improving the casting and molding effect of the workpiece.

[0033] In the initial stage of heat absorption, the cooling water 604 and the heat-absorbing metal ball 605 of this invention are isolated, ensuring that the heat absorption performance of the heat-absorbing metal ball 605 is not affected. The cooling water 604 then dissipates through its vaporization phase change to remove a large amount of heat, effectively ensuring local heat absorption and dissipation. As the first hot melt adhesive block 9 melts and penetrates, the unvaporized cooling water 604 enters the lower cavity 6012 and comes into contact with the heated heat-absorbing metal ball 605, further removing a large amount of heat during its vaporization phase change. This effectively enhances the local rapid cooling effect of this invention, thus effectively assisting in improving the heat dissipation effect of the steel shot layer 2. Most importantly, the cooling water 604 does not come into contact with the steel shot layer 2 or the mold body 1 during the entire process from heat absorption to vaporization phase change and discharge, effectively preventing any adverse effects on the casting quality of the workpiece caused by the use of the cooling water 604.

[0034] A corresponding filter screen 13 is detachably installed at the vent hole 11. The material guide tube 602 and the material guide hole 10, as well as the filter screen 13 and the vent hole 11, are detachably connected by threaded connection.

[0035] The heat-absorbing metal ball 605 and the spare metal ball 606 are made of aluminum. The spare metal ball 606 located on the hopper 603 is respectively placed on the top of a corresponding high-temperature resistant magnetic suction component 14. After the spare metal ball 606 enters the upper cavity 6011, the high-temperature resistant magnetic suction component 14 is attracted and fixed to the guide hole of the hopper 603.

[0036] The heat exchange container 601 of the present invention has a detachable filter screen 13 installed at the vent hole 11. The detachment and installation of the filter screen 13 facilitates the loading and unloading of the heat-absorbing metal ball 605 and the spare metal ball 606, as well as the sealing and loading of the first hot melt adhesive block 9. After the filter screen 13 is installed in place, it can effectively prevent the heat-absorbing metal ball 605 and the spare metal ball 606 from being discharged through the vent hole 11. At the same time, the present invention also uses aluminum to make the heat-absorbing metal ball 605 and the spare metal ball 606, and places a corresponding high-temperature resistant magnetic suction component 14 on the top of the spare metal ball 606 located on the collecting hopper 603. After the spare metal ball 606 enters the upper cavity 6011, the high-temperature resistant magnetic suction component 14 will be attracted and fixed to the guide hole of the collecting hopper 603 to seal the collecting hopper 603, thereby effectively preventing the heat-absorbing metal ball 605 and the spare metal ball 606 from being discharged through the guide pipe 602. To ensure that the heat-absorbing metal ball 605 and the spare metal ball 606 can be stably stored in the heat exchange container 601 during the removal of the workpiece after casting and the recycling of steel shot, thereby facilitating the secondary use of the heat-absorbing metal ball 605 and the spare metal ball 606 and facilitating the centralized removal of the hot melt adhesive adhering to the heat-absorbing metal ball 605 and the spare metal ball 606.

[0037] The heat exchange container 601 of the cooling acceleration assembly 6 has a right-angled cross-section. Corresponding connecting rods 15 are fixed to the outer walls of the heat exchange container 601, and the connecting rods 15 are fixedly installed to the iron shell 3 by corresponding locking bolts.

[0038] The molding cavities 4 are distributed around the upper sand shell 101 and the lower sand shell 102, and the molding cavities 4 are respectively connected to the inlet end of the pouring port 5 through corresponding material guiding channels 16. The upper sand shell 101 is provided with a shrinkage compensation component 17, which includes a pouring shrinkage compensation cavity 1701 disposed on the upper side of the middle part of the upper sand shell 101. The pouring shrinkage compensation cavity 1701 is connected to the material guiding channel 16, and a corresponding sand rod 1702 is fixedly attached downward at the top center of the pouring shrinkage compensation cavity 1701.

[0039] By introducing the feeding assembly 17, especially the sand rod 1702, the permeability of the area where the casting feeding cavity 1701 is located is improved, so that the molten steel in the casting feeding cavity 1701 can be fed to the forming cavity 4 in a timely manner, thereby reducing the probability of shrinkage cavities forming on the surface of the workpiece.

[0040] The top of the upper sand shell 101 is integrally formed and has several corresponding reinforcing ribs 18 arranged upwards, with the reinforcing ribs 18 inclined at the top of the upper sand shell 101. The bottom of the lower sand shell 102 is integrally formed and has several corresponding pads 19 arranged downwards.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
