Description

Technical Field

[0001] This utility model relates to the field of neutron molds, and in particular to a high-efficiency gravity neutron chiller device. Background Technology

[0002] When conventional neutrons are die-cast, sand is die-cast through a neutron mold without a chiller embedded in the neutron. Conventional neutrons do not have a chiller device; instead, cold water is applied to special locations, such as areas with thick walls that cool slowly. This method has a small cooling effect and sometimes cannot meet product requirements, easily leading to batch defects such as insufficient filling and porosity.

[0003] Therefore, it is necessary to propose a high-efficiency gravity neutron chill device to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency gravity neutron chiller that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency gravity neutron chill device includes a first neutron mold and a second neutron mold. A first mold groove and a second mold groove are symmetrically provided on opposite sides of the first neutron mold and the second neutron mold. A first chill is installed in the inner cavity of the first mold groove, and a second chill is installed in the inner cavity of the second mold groove. Positioning components are movably connected to the outer walls of both the first chill and the second chill.

[0007] Preferably, the outer wall of the second neutron mold is equipped with a push rod, which is used to push the formed neutron out of the inner cavity of the second neutron mold. The inner cavity of the second neutron mold is provided with a sand injection hole, which is used to inject sand into the inner cavity of the first neutron mold.

[0008] Preferably, the number of the first chill and the second chill is determined according to the thickness of the neutron and the slow cooling, and the first chill and the second chill are placed in the inner cavity of the first mold groove and the second mold groove according to the shape of the neutron.

[0009] Preferably, each of the first and second chills is provided with a positioning component at both ends. The positioning component is inserted into the inner cavity of the first and second neutron molds, and the side of the positioning component near the inner wall of the first and second neutron molds is inclined.

[0010] Preferably, both ends of the first chill and the second chill are provided with movable grooves, and the top and bottom of the inner cavity of the movable groove are symmetrically provided with moving grooves. A fixed rod is installed in the inner cavity of the moving groove, and a spring is wound around the outer wall of the fixed rod. One end of the spring is installed in the inner cavity of the moving groove, and the positioning component is movably connected in the inner cavity of the movable groove.

[0011] Preferably, movable blocks are symmetrically installed at the top and bottom of the positioning component. The movable blocks are movably connected in the inner cavity of the moving groove and sleeved on the outer wall of the fixed rod. The other end of the spring is connected to the movable blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This high-efficiency gravity neutron chiller device can facilitate faster and more convenient production and reduce waste of auxiliary materials during neutron molding. It can be installed in areas where cooling is slow or where applying cooling water is ineffective during neutron molding, thereby improving product qualification rates. The first and second chillers are pre-placed in the first and second neutron molds. After the molds are closed, the sand-shooting device is activated to inject sand through the sand-shooting holes into the first and second mold slots. After compression and shaping, the neutron is removed. At this point, the first and second chillers are embedded in the neutron's outer surface, forming a single unit. Since the neutron and the first and second chillers are integrated, there is no need to apply cooling water to specific parts of the neutron during later production. This provides better cooling, reduces the workload of applying cooling water manually during production, and decreases product defect rates and waste of auxiliary materials.

[0014] 2. This high-efficiency gravity neutron chill device, through the spring it is equipped with, can constantly push the movable block outward, so that the positioning component can be inserted into the inner cavity of the first neutron mold and the second neutron mold. Based on this, when installing the first chill and the second chill, it can play a reinforcing role and avoid positional displacement, thus improving the molding accuracy of the neutron.

[0021] 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.

[0022] like Figures 1-5 As shown, a high-efficiency gravity neutron chill device includes a first neutron mold 1 and a second neutron mold 2. A first mold groove 3 and a second mold groove 4 are symmetrically formed on opposite sides of the first and second neutron molds 1 and 2. A first chill 7 is installed in the inner cavity of the first mold groove 3, and a second chill 9 is installed in the inner cavity of the second mold groove 4. Positioning components 8 are movably connected to the outer walls of both the first chill 7 and the second chill 9. A push rod 5 is installed on the outer wall of the second neutron mold 2, used to eject the formed neutrons from the inner cavity of the second neutron mold 2. A sand injection hole 6 is formed in the inner cavity of the second neutron mold 2, used to inject sand into the inner cavity of the first neutron mold 1. The number of first chills 7 and second chills 9 is determined according to the thickness of the neutron cavity and the slow cooling rate. The first chills 7 and second chills 9 are placed in the first mold groove 3 and the second mold groove 4 according to the shape of the neutrons. In the inner cavity of the groove 4, each of the first chills 7 and the second chills 9 is provided with a positioning component 8 at both ends. The positioning component 8 is inserted into the inner cavity of the first neutron mold 1 and the second neutron mold 2. The side of the positioning component 8 near the inner wall of the first neutron mold 1 and the second neutron mold 2 is an inclined surface 10. Each of the first chills 7 and the second chills 9 is provided with a movable groove 12. The top and bottom of the inner cavity of the movable groove 12 are symmetrically provided with a moving groove 13. A fixed rod 14 is installed in the inner cavity of the moving groove 13. A spring 15 is wound around the outer wall of the fixed rod 14. One end of the spring 15 is installed in the inner cavity of the moving groove 13. The positioning component 8 is movably connected in the inner cavity of the movable groove 12. Movable blocks 11 are symmetrically installed at the top and bottom of the positioning component 8. The movable blocks 11 are movably connected in the inner cavity of the moving groove 13 and sleeved on the outer wall of the fixed rod 14. The other end of the spring 15 is connected to the movable block 11.

[0023] During neutron molding, production can be completed more conveniently and quickly, reducing waste of auxiliary materials. Chill iron devices can be added to areas where cooling is slow or the effect of applying cooling water is not obvious during neutron molding, thus improving product qualification rate. The first chill iron 7 and the second chill iron 9 are pre-placed in the first neutron mold 1 and the second neutron mold 2. After the first neutron mold 1 and the second neutron mold 2 are closed, the sand-shooting device is activated to inject sand through the sand-shooting hole 6 into the first mold groove 3 and the second mold groove 4. After compression and shaping, the neutron is removed. At this point, the first chill iron 7 and the second chill iron 9 can be embedded in the neutron's outer surface, forming... The neutron, the first chill 7, and the second chill 9 are integrated into one unit. After integration, there is no need to apply cold water to special parts of the neutron during later production. Based on this, it can achieve better cooling effect, reduce the workload of applying cold water during manual production, and reduce the product defect rate and waste of auxiliary materials. Through the set spring 15, the movable block 11 can be pushed outward at any time, so that the positioning component 8 can be inserted into the inner cavity of the first neutron mold 1 and the second neutron mold 2. Based on this, when installing the first chill 7 and the second chill 9, it can have a reinforcing effect and prevent positional displacement, thus improving the molding accuracy of the neutron.

[0024] It should be noted that this utility model is a high-efficiency gravity neutron chill device. When using it, select the appropriate number and shape of the first chill 7 and the second chill 9, and install them in the appropriate positions in the inner cavities of the first mold groove 3 and the second mold groove 4.

When the positioning component 8 is locked, the movable block 11 will be pushed outward by the spring 15, so that the positioning component 8 can play the role of positioning the first chill 7 and the second chill 9.

[0025] Close the first neutron mold 1 and the second neutron mold 2, and perform sand injection through the sand injection hole 6. After the mold making is completed, open the first neutron mold 1 and unload the finished product through the ejector pin 5.
