Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ingot forming of preformed solder pads, and particularly relates to an ingot forming device which is beneficial to slag separation and sequential solidification. Background Art
[0002] With the development of the electronic industry, preformed solder pads are widely used in fields such as PCB assembly, automotive parts components, connectors and terminal devices, chip connection, power module substrate attachment, filter connectors, optoelectronic packaging, MEMS packaging, microelectronics, high-power LED packaging, etc. The key to the pre-process of preformed solder pads lies in the melting and forming of ingots.
[0003] In the ingot casting process of preformed solder pads, the required alloy components need to be proportioned first, and then the raw materials are melted into liquid alloy in a melting furnace, and then the liquid alloy is poured into an ingot mold. After cooling, the mold is demolded to obtain an alloy ingot.
[0004] Currently, the molds used for ingot forming of preformed solder pads are integral. After cooling, the ingot can only be removed from the mold by relying on gravity or manual knocking, which may cause damage to the ingot or even damage the mold. In addition, during pouring, the oxidized slag and impurities in the liquid alloy are often poured into the ingot mold together, resulting in poor welding performance of the produced solder pads. Moreover, when the poured ingot cools, it cools from the periphery to the inside, often causing shrinkage cavities and porosity inside the ingot, which affects the performance and quality of the preformed solder pads. Summary of the Utility Model
[0005] The purpose of the embodiment of the utility model is to provide an ingot forming device which is beneficial to slag separation and sequential solidification, and solves the problems of slag inclusion, internal shrinkage cavities and porosity during the cooling and solidification process, and difficult demolding during the pouring process of the preformed solder pad ingot.
[0006] The embodiment of the utility model is implemented as follows:
[0007] An ingot forming device which is beneficial to slag separation and sequential solidification includes:
[0008] A mold, a cold water tank, a cooling plate, a simple funnel, a locking mechanism and a handle; the cold water tank has a water inlet and a water outlet, the cooling plate is installed closely on the cold water tank, the mold is arranged on the cooling plate, the mold has a left mold and a right mold, the locking mechanism is locked and connected between the left mold and the right mold, the handle is arranged on the outer sides of the left mold and the right mold, the left mold and the right mold surround to form an integral mold, and a casting port is opened. The simple funnel is arranged on the casting port, and a slag separation filter screen is arranged inside the simple funnel. The locking mechanism is a releasable locking mechanism.
[0009] Wherein, the left mold and the right mold are symmetrically surrounded and locked by 3 locking mechanisms to form a cuboid ingot cavity.
[0010] Wherein, the outer parts of the left mold and the right mold are L-shaped as a whole.
[0011] Wherein, two handles are respectively arranged on the outer sides of the left mold and the right mold.
[0012] Wherein, the cold water tank is in the shape of a cuboid.
[0013] The bottom of the inner cavity of the mold directly below the casting port is part of the upper surface of the cooling plate.
[0014] The embodiment of the utility model can block the oxide slag and other impurities in the molten liquid alloy in a simple funnel when the device is used to cast the preformed welding sheet ingot, so that the surface of the cast ingot is smoother and smoother, and the interior contains less impurities such as oxide slag; when the casting is completed and cooled and solidified, the bottom water tank begins to solidify the ingot sequentially from bottom to top, so that the shrinkage cavities and shrinkage of the cast ingot are completely concentrated in the upper layer of the ingot; after the ingot solidifies, the locking device is loosened, the mold is separated, and the ingot can be easily taken out without damaging the surface of the ingot, which greatly improves the efficiency of the ingot casting. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a three-dimensional structural diagram of the ingot forming device of the utility model. DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:
[0018] The utility model provides an ingot casting device composed of a slag separation tool, a detachable mold and a cooling tool, which effectively solves the problems of slag inclusion during the casting process of the preformed welding sheet ingot, internal shrinkage cavities and looseness during cooling and solidification, and demoulding difficulty.
[0019] like Figure 1 As shown, an ingot forming device that is conducive to slag separation and sequential solidification includes:
[0020] A mold 5, a cold water tank 8, a cooling plate 2, a simple funnel 6, a locking mechanism 3 and a handle 4; the cold water tank has a water inlet 7 and a water outlet 1, the cooling plate is installed tightly on the cold water tank, the mold is set on the cooling plate, the mold has a left mold and a right mold, the locking mechanism is locked and connected between the left mold and the right mold, the handle is set on the outside of the left mold and the right mold, the left mold and the right mold are combined to form a whole mold, and a casting port is opened, the simple funnel is set on the casting port, a slag filter is set in the simple funnel, and the locking mechanism is a releasable locking mechanism.
[0021] In the figure, the left mold and the right mold are symmetrically enclosed and locked using three locking mechanisms, so that the mold forms a rectangular ingot casting cavity; the exterior of the left mold and the right mold are L-shaped as a whole; and two handles are respectively provided on the outer sides of the left mold and the right mold.
[0022] In the figure, the cold water tank is in the shape of a rectangular parallelepiped.
[0023] The bottom of the inner cavity of the mold just below the casting port is part of the upper surface of the cooling plate, so that the ingot at the casting position directly contacts the cooling plate, which is more conducive to the cooling effect.
[0024] When assembling, the left mold and the right mold are enclosed and locked by the locking mechanism to form a mold as a whole. When opening, the locking mechanism is loosened, and the handle is held to separate the left mold and the right mold.
[0025] The device of the utility model mainly comprises: a rectangular cold water tank with a water inlet and outlet, two symmetrical left and right molds with a cross section of "L", and a simple slag separation funnel;
[0026] The left mold and the right mold are symmetrically enclosed and locked using three locking mechanisms to form a rectangular ingot casting cavity; the interior of the cooling water tank is hollow, and two interfaces are externally connected to an inlet pipe and an outlet pipe. Cooling water flows through the cold water tank to take away the heat of the cooling steel plate of the box; during casting, a simple slag separator funnel is placed in the mold, and the mold is then placed on the cooling water tank for use.
[0027] The materials used for each component of this device are as follows: The left mold and the right mold are symmetrical, and the overall material is heat-treated stainless steel. The locking mechanism 3, the handle 4, the simple funnel 6, the cold water tank water inlet 7 and the water outlet 1, and the cold water tank cooling plate are all made of stainless steel. The cold water tank body is made of an AL-Cu-Mg series aluminum alloy. During the melting process of the alloy, first assemble and lock the mold, then connect the cold water tank to the inlet and outlet pipes. When the alloy is melted into a liquid state and reaches the specified temperature, casting can be carried out. The liquid alloy is poured out from the melting furnace, passes through the simple funnel for slag separation and flow stabilization, and then enters the ingot mold. The casting speed should be fast first and then slow. When the alloy just reaches the top of the mold, the casting is completed, and the simple mold is taken out. Open the switches of the cooling water inlet and outlet to connect the cooling water tank to the cooling water. The ingot in the mold starts to cool, and the ingot in the mold starts to solidify from bottom to top. The cooling time is about 8 minutes. Then, the locking device can be loosened, the mold can be separated, and the ingot can be taken out to obtain an ingot with less oxidation slag, defects concentrated in the upper layer, and suitable for making preformed solder pads.
[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
