Description

Technical Field

[0001] This utility model is a die-casting mold for a platform, belonging to the field of die-casting mold technology. Background Technology

[0002] Die casting molds are a method of casting liquid forging, a process completed on a dedicated die casting and forging machine. The basic process is as follows: molten metal is first cast and filled into the mold cavity at low or high speed. The mold has movable cavity surfaces, and as the molten metal cools, pressure is applied for forging, eliminating shrinkage cavities and porosity defects in the blank, and also achieving a forged, fragmented grain structure in the blank.

[0003] Chinese Patent No. CN218891169U discloses a platform die-casting mold. This device uses multiple sets of heat-conducting fins that abut against the lower mold, evenly arranged inside a heat dissipation pipe. The heat-conducting fins serve as the heat transfer medium, and a cooling liquid is then introduced into the heat dissipation pipe as the heat dissipation medium. The low-temperature cooling liquid exchanges heat with the high-temperature heat-conducting fins inside the heat dissipation pipe, assisting the heat-conducting fins in cooling down, thereby achieving the purpose of assisting the workpiece in rapid heat dissipation and cooling. This design optimizes the heat dissipation and cooling capacity of the mold compared to the prior art and significantly reduces the time consumed in waiting for the workpiece to cool down. However, this device only uses water cooling to assist the workpiece in heat dissipation and cooling, and its heat dissipation efficiency still needs to be improved. There is an urgent need for a platform die-casting mold to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1-3 This utility model provides a technical solution: a die-casting mold base, including a lower die-casting mold base 1, an upper die-casting mold base 4, a cooling water pipe 13, and a cooling fan 18. The lower die-casting mold base 1 has multiple die-casting grooves 2 at its upper end, and each of the multiple die-casting grooves 2 has a through-hole groove 10. Lower molds 3 are placed in each of the multiple die-casting grooves 2. Multiple upper molds 5 are fixed to the lower end of the upper die-casting mold base 4. The upper die-casting mold base 4 covers the upper end of the lower die-casting mold base 1, and the multiple upper molds 5 are respectively located inside the upper ends of the multiple die-casting grooves 2. Heat-conducting plates 9 are horizontally fixed to the lower ends of each of the multiple lower molds 3, and multiple heat-conducting fins are vertically arranged at the lower ends of each of the multiple heat-conducting plates 9. The die-casting mold has multiple heat-conducting fins 11 inserted into multiple insertion slots 10. Sliding grooves 12 are provided through the front and rear ends of the side surfaces of the multiple heat-conducting fins 11. Two cold water pipes 13 are provided, which are horizontally inserted through the front and rear ends of the die-casting mold lower seat 1 and are located at the upper end of the multiple sliding grooves 12. Multiple mounting slots 17 are provided at equal intervals from left to right on the lower rear end of the die-casting mold lower seat 1. A cooling fan 18 is installed in each of the multiple mounting slots 17 by bolts. The multiple cooling fans 18 are located directly behind the multiple heat-conducting fins 11. This design solves the problem that the heat dissipation efficiency of the original device still needs to be improved.

[0018] As the first embodiment of this utility model: positioning grooves are provided around the lower end of the die-casting mold upper seat 4, and positioning blocks 8 are provided around the upper end of the die-casting mold lower seat 1. Multiple positioning blocks 8 are inserted into multiple positioning grooves. By adding positioning blocks 8, the die-casting mold upper seat 4 is more stable on the upper end of the die-casting mold lower seat 1. A main pouring port 7 is provided in the middle of the upper end of the die-casting mold upper seat 4. Multiple upper molds 5 are connected to the main pouring port 7 by pouring branch ports 6. The main pouring port 7 and pouring branch ports 6 facilitate the pouring use of this device. The right ends of the two cold water pipes 13 are connected to the outlet of the water pump 15 through a three-way pipe 14. The inlet of the water pump 15 is connected to the cold water tank 16. The added water pump 15 and cold water tank 16 can provide cold water to the two cold water pipes 13 through the three-way pipe 14.

[0019] A slot 20 is provided on the lower front side of the die-casting mold base 1, and a movable filter 21 is installed in the slot 20 by multiple hinges 19. A swing handle 22 is installed at the front end of the movable filter 21. The added movable filter 21 can prevent external dust from easily entering the location of multiple heat-conducting fins 11.

[0020] As a second embodiment of this utility model: the upper die-casting mold seat 4 is placed on top of the lower die-casting mold seat 1. At this time, multiple upper molds 5 are located at the upper ends of multiple die-casting grooves 2 respectively. External pouring equipment can then be operated to perform pouring operations through the main pouring port 7 and multiple pouring branch ports 6. After the workpiece is poured at the lower mold 3 (at this time, the heat of the workpiece will be transferred to multiple heat-conducting fins 11 through the lower mold 3 and the heat-conducting plate 9), the water pump 15 is started. The water pump 15 can then transfer the cold water in the cold water tank 16 to the two cold water pipes 13 through the three-way pipe 14. The two cold water pipes 13 are located in multiple sliding grooves. Inside the mold 12, the cold water inside exchanges heat with the multiple heat-conducting fins 11, thereby cooling the multiple heat-conducting fins 11. At the same time, multiple cooling fans 18 are activated, which can draw cold air from the outside to the lower end of the die-casting mold base 1. After passing through the multiple heat-conducting fins 11, the heat from the multiple heat-conducting fins 11 is carried to the outside through the movable filter 21. Thus, the multiple heat-conducting fins 11 can quickly remove the heat from the workpiece through the heat-conducting plate 9 and the lower mold 3, thereby achieving the purpose of rapid cooling of the workpiece and greatly reducing the waiting time for the workpiece to cool down.
