Description

Technical Field

[0001] This utility model relates to the field of zinc alloy liquid cooling and forming technology, specifically to a zinc alloy liquid slow cooling and forming device. Background Technology

[0002] Zinc alloys are alloys composed of zinc as a base with the addition of other elements, commonly including aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloys have low melting points, good fluidity, and are easy to weld, braze, and plastically process. They are corrosion-resistant in the atmosphere, and scrap is easily recycled and remelted. However, they have low creep strength and are prone to dimensional changes due to natural aging. Zinc alloys can be classified into two categories according to their processing technology: wrought zinc alloys and cast zinc alloys. Cast zinc alloys have better fluidity and corrosion resistance, making them suitable for die-casting instruments, automotive parts housings, etc. Molten zinc alloy is injected into a mold for molding. Modern molds often use cooling water spray for cooling to improve efficiency.

[0003] However, the zinc alloy being formed at this time is in a high-temperature state. Rapid cooling may cause the formed zinc alloy to crack or affect its strength, which may have the opposite effect. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that the formed zinc alloy is in a high temperature state, and rapid cooling will cause the formed zinc alloy to crack or affect its strength, which may be counterproductive.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a zinc alloy liquid slow cooling and forming device, comprising: Cooling pipes are spirally wound around the outer wall of the mold body, and adjacent outer walls of the cooling pipes abut against each other to form a heat insulation layer covering the outer wall of the mold body. A liquid storage tank, with both ends of the cooling pipe connected to the liquid storage tank; and a pump body, which is installed inside the liquid storage tank.

[0006] Preferably, it further includes a heat-conducting layer, which is disposed between the insulation layer and the mold body.

[0007] Preferably, it also includes a heat insulation layer, which covers the outside of the insulation layer.

[0008] Preferably, it also includes a heat dissipation mechanism, which is installed inside the liquid storage tank.

[0009] Preferably, the heat dissipation mechanism includes: a rotating shaft and blades; the rotating shaft is rotatably installed in the liquid storage tank, and a plurality of blades are fixedly installed on the rotating shaft, and the plurality of blades are evenly spaced along the circumferential direction of the rotating shaft; the outlet of the cooling pipe is perpendicularly arranged to the axis of the rotating shaft and faces the blades.

[0010] Preferably, the end of the blade furthest from the axis of rotation is bent in the direction of blade rotation.

[0011] Preferably, the upper end of the liquid storage tank is provided with heat dissipation holes.

[0012] Preferably, a valve is installed on the cooling pipe.

[0013] Compared with the prior art, the present invention has at least the following advantages: 1. In this utility model, the storage tank contains coolant; the pump body is controlled to pump the coolant from the storage tank into the cooling pipe, which cools the zinc alloy liquid in the mold body. This achieves the function of cooling the zinc alloy liquid. The design of the cooling pipe being wound into an insulation layer can effectively prevent the loss of heat from the mold body, thus ensuring that most of the heat in the zinc alloy liquid is absorbed by the coolant, thereby reducing the cooling rate of the zinc alloy liquid. After the coolant absorbs the heat, its own temperature rises, which can further reduce the cooling rate of the zinc alloy liquid, effectively preventing the rapid cooling of the zinc alloy liquid from causing cracking of the molded zinc alloy or affecting its strength.

[0014] 2. In this invention, the heat-conducting layer allows the cooling pipes to abut against the outer wall of the mold body, increasing the contact area between the cooling pipes and the mold body, thus facilitating the cooling of the zinc alloy liquid by the coolant. The heat insulation layer effectively reduces heat loss from the cooling pipes; consequently, it reduces the influence of the outside on heat, allowing for more precise heat control.

[0015] 3. In this utility model, the pump body draws the coolant into the cooling pipe and discharges it through the outlet. The coolant is discharged onto the blades through the outlet of the cooling pipe, thereby driving the rotating shaft to rotate, thus realizing the rotation of multiple blades. The blades stir and agitate the coolant in the storage tank, thereby increasing the heat dissipation area of ​​the coolant and thus achieving heat dissipation of the coolant.

[0016] 4. In this utility model, the cooling rate of the zinc alloy liquid is controlled by controlling the flow rate of the cooling pipe through a valve. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] See Figures 1-2 The present invention provides an embodiment of a zinc alloy liquid slow cooling molding device, comprising: a cooling pipe 1, a liquid storage tank 2, and a pump body 3; the cooling pipe 1 is spirally wound around the outer wall of the mold body 8, and the adjacent outer walls of the cooling pipe 1 abut against each other to form a heat insulation layer covering the outer wall of the mold body 8; both ends of the cooling pipe 1 are respectively connected to the liquid storage tank 2; furthermore, the upper end of the liquid storage tank 2 is provided with heat dissipation holes to facilitate heat dissipation of the liquid storage tank 2; the pump body 3 is installed inside the liquid storage tank 2.

[0023] In practice, the storage tank 2 contains coolant; the pump 3 is controlled to pump the coolant from the storage tank 2 into the cooling pipe 1. The cooling pipe 1 cools the zinc alloy liquid in the mold body 8, thus achieving the function of cooling the zinc alloy liquid. The design of the cooling pipe 1, which is wrapped into an insulation layer, can effectively prevent the loss of heat from the mold body 8, thereby ensuring that most of the heat in the zinc alloy liquid is absorbed by the coolant, thereby reducing the cooling rate of the zinc alloy liquid. After the coolant absorbs the heat, its own temperature rises, which can further reduce the cooling rate of the zinc alloy liquid, effectively preventing the zinc alloy liquid from cracking or affecting its strength due to rapid cooling.

[0024] See Figures 1-2In other embodiments, a heat-conducting layer 4 is also included, which is disposed between the insulation layer and the mold body 8. In specific implementation, the heat-conducting layer 4 can be made of heat-conducting materials such as copper and graphene. By setting the heat-conducting layer 4, the cooling pipe 1 abuts against the outer wall of the mold body 8 through the heat-conducting layer 4, increasing the contact area between the cooling pipe 1 and the mold body 8, thereby facilitating the cooling of the zinc alloy liquid by the coolant.

[0025] See Figures 1-2 In other embodiments, a heat insulation layer 5 is also included, which covers the outside of the insulation layer. In specific implementation, the heat insulation layer 5 can be made of heat insulation materials such as heat insulation film or vacuum insulation panel; by setting the heat insulation layer 5, heat loss from the cooling pipe 1 can be effectively reduced; thus, the influence of the outside on heat can be reduced, and heat can be controlled more precisely.

[0026] See Figures 1-2 In other embodiments, a heat dissipation mechanism 6 is also included, which is installed inside the liquid storage tank 2. The heat dissipation mechanism 6 dissipates heat from the liquid storage tank 2 to reduce the temperature of the coolant and control the coolant temperature. Further, the heat dissipation mechanism 6 includes a rotating shaft 61 and blades 62. The rotating shaft 61 is rotatably installed inside the liquid storage tank 2, and multiple blades 62 are fixedly installed on the rotating shaft 61, with the blades 62 evenly spaced along the circumferential direction of the rotating shaft 61. The outlet of the cooling pipe 1 is perpendicularly arranged to the axis of the rotating shaft 61 and faces the blades 62.

[0027] In practice, the pump body 3 operates, drawing coolant into the cooling pipe 1 and discharging it through the outlet. The coolant then flows through the outlet of the cooling pipe 1 onto the blades 62, which in turn drive the rotating shaft 61 to rotate. This rotation of multiple blades 62 agitates and agitates the coolant in the storage tank 2, increasing the heat dissipation area and thus facilitating cooling. Furthermore, the end of the blade 62 furthest from the rotating shaft 61 is bent in the direction of rotation; this bending enhances the agitation of the coolant during rotation, further reducing the rate of coolant cooling.

[0028] See Figures 1-2 In another embodiment, a valve 7 is installed on the cooling pipe 1; the flow rate of the cooling pipe 1 is controlled by the valve 7, thereby controlling the cooling rate of the zinc alloy liquid.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
