Description

Technical Field

[0001] The utility model relates to the technical field of casting moulds, in particular to a casting mould for preventing overflow. Background Art

[0002] A casting mold is a material that is easily formed into the shape of a part in advance in order to obtain the structural shape of the part. The mold is then placed in a sand mold, so that a cavity with the same size as the part is formed in the sand mold. A flowing liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

[0003] Chinese patent authorization announcement number CN213224193U discloses an anti-deviating casting mold, including a casting mold, a top cover is buckled on the top of the casting mold, support rods are fixedly connected at both ends of the casting mold, the outer wall of the support rod is tapped with threads, through holes are opened at both ends of the upper surface of the top cover, a cylinder is threadedly connected to the top of the support rod, a baffle is welded on the top of the cylinder, and the baffle fits tightly with the top cover. The anti-deviating casting mold is installed with support rods at both ends of the casting mold, and the top cover is inserted into the support rod through the through hole opened thereon, so that the top cover fits with the casting mold, effectively avoiding the occurrence of deviation when the top cover is connected with the casting mold, and the cylinder is inserted into the inside of the through hole and connected to the top thread of the support rod, and drives the baffle to move, which is effective and convenient for the top cover to fit tightly on the casting mold, increasing its stability during work, and is simple to operate and easy to disassemble. The above-mentioned existing technical solution has the following shortcomings: support rods are installed at both ends of the casting mold, and the support rods are inserted into the top cover through the through holes opened thereon, so that the top cover fits the casting mold, effectively avoiding the offset when the top cover is connected to the casting mold, but the technical solution does not have a simpler structure in terms of limiting, and it is also manually clamped and fixed. Manual clamping has a certain degree of error, and gaps are easily generated between the mold bases, which will cause overflow during pouring. Therefore, we need to design an anti-overflow casting mold to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a casting mold which prevents overflow, so as to solve the problem that the casting mold proposed in the above background technology is prone to overflow during the casting process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-overflow casting mold, comprising a base, a left casting mold base and a right casting mold base are respectively installed on the top of the base, positive and negative thread screws are installed inside the base, and threaded sleeves are evenly installed on the outside of the positive and negative thread screws, and the tops of the threaded sleeves are respectively connected to the left casting mold base and the right casting mold base, a motor is installed on one side of the base, a mold body is installed inside the left casting mold base and the right casting mold base, and mold cavities are evenly arranged inside the mold body, and a casting groove is arranged on the top of the connection between the left casting mold base and the right casting mold base.

[0006] When using an anti-overflow casting mold of the present technical solution, the motor can replace the manual adjustment error sense. At the same time, the mutual engagement of the positioning block and the positioning groove can achieve a positioning effect to prevent the left casting mold base and the right casting mold base from offsetting during use.

[0007] Preferably, positioning blocks are evenly installed on the side of the left casting mold base close to the right casting mold base, positioning grooves are evenly arranged on the side of the right casting mold base close to the left casting mold base, and the positioning grooves are connected to the positioning blocks, grooves are evenly arranged on both sides of the mold body, and bolts are evenly installed inside the grooves.

[0008] Preferably, the size of the positioning blocks is equal to the size of the positioning grooves, and the cross-section of the positioning blocks is trapezoidal.

[0009] Preferably, ventilation grooves are evenly arranged inside the left casting mold base and the right casting mold base, mounting frames are installed on the outer sides of the left casting mold base and the right casting mold base, and filters are installed inside the mounting frames.

[0010] Preferably, a card block is evenly installed on one side of the filter screen close to the left casting mold base and the right casting mold base, and the outer sides of the left casting mold base and the right casting mold base are evenly provided with a card slot, and the card slot is connected to the card block through a magnet.

[0011] Preferably, the size of the card slots is equal to the size of the card blocks, and the card blocks are distributed at the four corners inside the filter screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the anti-overflow casting mold not only realizes the anti-overflow function, but also realizes the anti-sticking function;

[0013] (1) By starting the motor and under the action of the threaded connection, the left casting mold base and the right casting mold base can be driven to move inward synchronously to fit the two together. The motor can replace the manual adjustment error. At the same time, under the action of the mutual engagement of the positioning block and the positioning groove, the positioning effect can be achieved to prevent the left casting mold base and the right casting mold base from offsetting during use, thereby causing overflow during the pouring process, affecting the subsequent processing work;

[0014] (2) By setting up multiple sets of ventilation grooves, a cooling effect can be achieved. After the pouring work is completed, cold air can be introduced into the interior of the left casting mold base and the right casting mold base through the ventilation grooves, further accelerating the cooling of the model inside the mold body, thereby facilitating subsequent demolding to prevent the mold from sticking when forced demolding when the mold is not completely cooled down. This further improves work efficiency. At the same time, the filter net can prevent dust from entering the interior of the left casting mold base and the right casting mold base, thereby affecting the use of the mold body.
