This mold can ensure the accuracy and quality of the housing, making it meet the design requirements, and can be used to achieve mass production.

[0003] Authorization announcement number CN213559758U discloses a buffer box. This device mainly improves production output by producing 12 products per box compared to the previous method of producing two products per box. In addition, compared to previous molds, the outer mold of this utility model uses coated sand, which improves the strength and quality of the sand mold. However, the following defects still exist in the actual use of the device:

[0004] The aforementioned patent mainly enables the production of 12 products per box, which increases product output compared to the previous production of two products per box. However, when multiple products are produced simultaneously, the hot gas poured into the mold tends to concentrate at a high density and is difficult to discharge evenly. This results in defects on the surface of the buffer cast in the mold cavity above and below the mold, reducing the precision of the buffer casting and the casting quality. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 The present invention provides an embodiment of a buffer box casting mold, comprising a lower mold base 1 and an upper mold base 2. Multiple sets of buffer mold cavities 6 are arranged side-by-side on both sides of the top of the lower mold base 1. Multiple sets of casting mold cavities 7, perpendicular to the buffer mold cavities 6, are arranged side-by-side on both sides of the bottom of the upper mold base 2. Vent holes 3 are symmetrically connected to the tops of the two rows of casting mold cavities 7 on the same side. A groove 4 is provided on the top of the upper mold base 2. The lower mold base 1 and the upper mold base 2 are box-shaped structures. The buffer mold cavities 6 inside the lower mold base 1 and the upper mold base 2 are arranged side-by-side with the casting mold cavities 7 and their vertical surfaces are opposite each other, increasing the mold cavity sealing performance and improving the casting accuracy.

[0021] A sealing groove 11 is provided at the top of the lower mold base 1 near the edge of the buffer mold cavity 6. A sealing ring 10 that seals with the sealing groove 11 is provided at the bottom of the upper mold base 2 near the edge of the casting mold cavity 7. An intermediate groove 8 is provided inside the upper mold base 2, and multiple sets of first exhaust channels 9 are provided inside the intermediate groove 8. Every three sets of first exhaust channels 9 are interconnected, and every two sets of first exhaust channels 9 are interconnected with the casting mold cavity 7. An exhaust port 5 is connected to the top of the first exhaust channel 9. A splicing groove 12 is provided at the middle position of the bottom of the upper mold base 2. A splicing protrusion 13 is provided at the middle position of the top of the lower mold base 1. A second exhaust channel 14 is connected between the two rows of buffer mold cavities 6 on the same side, and the top of the second exhaust channel 14 is connected to a second splicing pipe 16 and two sets of first splicing pipes 15 respectively.

[0022] Multiple sets of vents 5 are set inside the groove 4. Every three sets of vents 5 are connected to the first vent channel 9, the first splicing pipe 15, and the second splicing pipe 16 to improve the venting efficiency of the upper and lower mold cavities and increase the molding effect of the buffer.

[0023] Example 1, such as Figure 1-3 As shown, the sealing ring 10 and the sealing groove 11 are annular structures. The sealing ring 10 extends to the inner side of the sealing groove 11 for sealing. The splicing groove 12 and the splicing protrusion 13 are conical structures. The conical groove of the splicing groove 12 and the splicing protrusion 13 engage and seal. Through the structural engagement of the annular sealing ring 10 and the sealing groove 11, the sealing performance of the buffer mold cavity 6 and the casting mold cavity 7 is improved. By utilizing the conical engagement structure of the splicing groove 12 and the splicing protrusion 13, the combined sealing of the lower mold base 1 and the upper mold base 2 is increased, while promoting the splicing and connection of the three sets of first exhaust channels 9 and the first splicing pipe 15, so as to combine multiple exhaust pipes and improve exhaust efficiency.

[0024] Example 2, as Figure 1-2 As shown, the two rows of casting mold cavities 7 on the same side and the three sets of first exhaust channels 9 are on the same horizontal plane, and a connecting pipe is provided between the two sets of casting mold cavities 7 and the two sets of first exhaust channels 9.

[0025] Working principle: The buffer housing is cast in the mold;

[0026] When the buffer is cast using the housing mold, the upper mold base 2 and the lower mold base 1 close together, causing the upper mold base 2 to drive the casting mold cavity 7 to be sealed by the locking ring 10 and the sealing groove 11. This improves the sealing performance of the casting mold cavity 7 and the buffer mold cavity 6. When the upper mold base 2 and the lower mold base 1 close together, the splicing groove 12 engages with the splicing protrusion 13 for calibration and positioning. This allows the internal connecting pipe structures of every two sets of side-by-side casting mold cavities 7 and buffer mold cavities 6, as well as the intermediate groove 8 between them, to be spliced ​​together. This causes the three sets of first exhaust channels 9 to respectively engage with the second splicing pipe 16 and the outer sides of the two sets of first splicing pipes 15, so as to facilitate ventilation. When the buffer body is formed through the casting mold cavity 7 and the buffer mold cavity 6, the gas is introduced into the interconnected first exhaust channel 9 through the exhaust hole 3 and the second exhaust channel 14 between the two sets of buffer mold cavities 6. The gas is introduced into the interconnected first exhaust channel 9 through the second exhaust channel 14 and the second splicing pipe 16 connected to the two sets of first splicing pipes 15. The two sets of casting mold cavities 7 are structurally connected to the first exhaust channel 9, so that the gas produced by each pair of casting mold cavities 7 and buffer mold cavity 6 is coordinated through the connection of pipes and finally evenly discharged through the three sets of first exhaust channels 9 and exhaust port 5, which improves the gas exhaust efficiency and increases the stability of casting temperature control.
