Description

Technical Field

[0001] This utility model specifically relates to the field of mold technology, and more specifically to a precision mold with temperature and pressure monitoring functions. Background Technology

[0002] A casting mold is a tool used to inject liquid metal or other materials into a cavity of a specific shape, allowing it to cool and solidify to form the desired shape. Metal molds are generally made of metal materials such as cast iron, cast steel, or aluminum alloys, and have the advantages of high precision, good surface quality, high production efficiency, and reusability.

[0003] Chinese Patent Publication No. CN 212384542 U provides a casting mold with a beryllium copper block, which includes a lower mold, a lower cavity on the top surface of the lower mold, and a beryllium copper block embedded on the bottom surface of the lower cavity.

[0004] The casting mold in the aforementioned patent can only perform the function of mold forming. It cannot detect the temperature and pressure inside the mold during the casting process. It is also impossible to have a direct understanding of the internal conditions during the casting process, which can easily lead to defects in the parts. Utility Model Content

[0005] The purpose of this invention is to provide a precision mold with temperature and pressure monitoring functions. When the mold is closed, the closing pressure of the upper and lower molds can be detected to avoid defects in the mold or product caused by incomplete or excessive closure. The temperature sensor can monitor the temperature inside the mold to determine whether the flow of molten metal is balanced during the casting process, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A precision mold with temperature and pressure monitoring functions includes an upper mold assembly and a lower mold assembly. The lower mold assembly includes a lower mold base, a lower mold core fixed in the middle of the lower mold base, and rectangular through slots formed on both sides of the lower mold core. A sliding module is slidably connected in the through slots. The sliding module is slidably connected to a sliding seat, and a protrusion extends upward from the middle of the top of the sliding seat. A groove is formed on the top of the protrusion, and a pressure sensor is provided in the groove. Multiple temperature probes are also embedded on both sides of the lower mold core.

[0008] As a further technical solution of this utility model, the sliding seat is fixed to the intermediate plate by countersunk bolts, and round holes are opened at the four corners of the intermediate plate and the lower mold base, and are sleeved on the guide cylinder; the lower end of the guide cylinder is fixed inside the pad.

[0009] As a further technical solution of this utility model, two pads are provided, and the two pads are fixed symmetrically on the base.

[0010] As a further technical solution of this utility model, a base plate is provided between the two pads. The base plate is fixed to the base by countersunk bolts, and multiple model rods are provided on the upper surface of the base plate, with the upper end of the model rods extending through to the upper end of the lower mold core.

[0011] As a further technical solution of this utility model, the upper mold assembly includes a top seat, and an upper mold base is fixed at the bottom of the top seat; an upper mold core is fixed at the middle position of the bottom of the upper mold base, and multiple positioning posts are provided on both sides of the upper mold core; a casting gate is provided through the middle position of the top seat and the upper mold base.

[0012] As a further technical solution of this utility model, protrusions are provided on both sides of the casting port, and the two protrusions correspond to the two pressure sensors respectively.

[0013] As a further technical solution of this utility model, the bottom of the upper mold base is also provided with four positioning posts; the positioning posts are connected to the positioning holes opened on the sliding seat; a guide post is fixed at each of the four corners of the bottom of the upper mold base; the guide posts are slidably connected in the guide cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, when the mold is closed, the pressure sensor set on the top of the protrusion frame will contact the upper mold assembly and monitor the mold closing force. This ensures that the upper mold assembly and the lower mold assembly can stop after reaching a reasonable mold closing force, which can avoid the situation that the upper and lower molds do not close tightly due to insufficient mold closing force. At the same time, it can also avoid mold damage caused by hard contact between the upper and lower molds due to excessive closure.

[0016] 2. In this utility model, multiple temperature probes are evenly distributed on both sides of the lower mold core. During casting, the multiple temperature probes can detect the temperature inside the mold. After casting is completed, the temperatures of the multiple temperature probes are compared. If the temperatures shown by the multiple temperature probes are the same, or the temperature difference is small, it proves that the casting effect of the mold is good. If the temperature difference of the multiple temperature probes is large, it proves that the mold may be partially blocked due to impurities or poor flow of molten metal. It is necessary to check the casting channel to avoid the occurrence of too many defective products.

[0017] 3. In this utility model, during the mold closing process, the guide post is slidably connected inside the guide cylinder, which can ensure the linearity of the movement of the upper and lower molds when they are closed. This can avoid misalignment when the upper and lower molds are closed, thereby improving the accuracy of mold closing and improving product quality. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5In this embodiment of the present invention, a precision mold with temperature and pressure monitoring functions includes an upper mold assembly 1 and a lower mold assembly 2. The lower mold assembly 2 includes a lower mold base 21, a lower mold core 22 fixed in the middle of the lower mold base 21, and rectangular through slots formed on the lower mold base 21 on both sides of the lower mold core 22. A sliding module 25 is slidably connected in the through slots. The sliding module 25 is slidably connected to a sliding seat 24, and a protrusion 211 extends upward from the middle of the top of the sliding seat 24. A groove is formed on the top of the protrusion 211, and a pressure sensor 212 is provided in the groove. Multiple temperature probes 213 are also embedded on both sides of the lower mold core 22. The casting port 16 has protrusions 15 on both sides, and the two protrusions 15 correspond to the two pressure sensors 212 respectively.

[0028] By adopting the above technical solution, when the mold is closed, the pressure sensor 212 set on the top of the protrusion frame 211 will contact the upper mold assembly 1 and monitor the mold closing force. This can ensure that the upper mold assembly 1 and the lower mold assembly 2 can stop after reaching a reasonable mold closing force, which can avoid the situation that the upper and lower molds are not closed tightly due to insufficient mold closing force, and can also avoid mold damage caused by hard contact between the upper and lower molds due to excessive closure of the upper and lower molds.

[0029] Multiple temperature probes 213 are evenly distributed on both sides of the lower mold core 22. During casting, the multiple temperature probes 213 can detect the temperature inside the mold. After casting is completed, the temperatures of the multiple temperature probes 213 are compared. If the temperatures shown by the multiple temperature probes 213 are the same, or the temperature difference is small, it proves that the casting effect of the mold is good. If the temperature difference of the multiple temperature probes 213 is large, it proves that the mold may be partially blocked due to impurities or poor flow of molten metal. It is necessary to check the casting channel to avoid the occurrence of too many defective products.

[0030] In this embodiment, the sliding seat 24 is fixed to the intermediate plate 23 by countersunk bolts, and the intermediate plate 23 and the lower mold base 21 are provided with round holes at the four corners and are sleeved on the guide cylinder 26; the lower end of the guide cylinder 26 is fixed inside the pad block 27.

[0031] Furthermore, the bottom of the upper mold base 12 is provided with four positioning posts 14; the positioning posts 14 are connected to the positioning holes opened on the sliding seat 24; a guide post 13 is fixed at each of the four corners of the bottom of the upper mold base 12; the guide post 13 is slidably connected in the guide cylinder 26.

[0032] By adopting the above technical solution, during the mold closing process, the guide post 13 is slidably connected inside the guide cylinder 26, which can ensure the linearity of the movement of the upper and lower molds when they are closed. This can avoid misalignment when the upper and lower molds are closed, thereby improving the accuracy of mold closing and improving product quality.

[0033] Furthermore, the positioning pin 14 is connected to the positioning hole on the sliding seat 24. Since the sliding seat 24 is slidably connected to the intermediate plate 23, when the mold is closed, the positioning pin 14 can force the two sliding seats 24 to move in opposite directions, so that the two sliding seats 24 close to form a certain cavity, thereby realizing the casting and molding of the product.

[0034] When the mold is opened, the sliding seat 24 loses the constraint of the positioning post 14, which makes the two sliding seats 24 relatively free, making it easier to pick up the product.

[0035] In this embodiment, two pads 27 are provided, and the two pads 27 are fixed symmetrically on the base 210. A base plate 29 is also provided between the two pads 27. The base plate 29 is fixed to the base 210 by countersunk bolts, and a plurality of model rods 28 are provided on the upper surface of the base plate 29, with the upper ends of the model rods 28 extending through to the upper end of the lower mold core 22.

[0036] By adopting the above technical solution, some products need to have holes such as positioning holes and through holes reserved during casting; by setting the model rod 28, the product can be cast in one piece.

[0037] In this embodiment, the upper mold assembly 1 includes a top seat 11, and an upper mold base 12 is fixed to the bottom of the top seat 11; an upper mold core is fixed at the middle position of the bottom of the upper mold base 12, and multiple positioning posts 14 are provided on both sides of the upper mold core; a casting port 16 is provided through the middle position of the top seat 11 and the upper mold base 12.

[0038] The working principle of this utility model is as follows: When the mold is closed, the pressure sensor 212 set on the top of the protrusion frame 211 will contact the upper mold assembly 1 and monitor the mold closing force. This ensures that the upper mold assembly 1 and the lower mold assembly 2 can stop after reaching a reasonable mold closing force, which can avoid the situation where the upper and lower molds do not close tightly due to insufficient mold closing force. At the same time, it can also avoid mold damage caused by hard contact between the upper and lower molds due to excessive closing of the upper and lower molds. Moreover, during the mold closing process, the guide post 13 is slidably connected in the guide cylinder 26, which can ensure the linearity of the movement of the upper and lower molds when closing. This can avoid the situation where the upper and lower molds are misaligned when closing, thereby improving the accuracy of the upper and lower mold closing and improving the quality of the product. In addition, the positioning post 14 can force the two sliding seats 24 to move in opposite directions, so that the two sliding seats 24 close into a certain cavity, thereby realizing the casting and molding of the product.

[0039] Multiple temperature probes 213 are evenly distributed on both sides of the lower mold core 22. During casting, the multiple temperature probes 213 can detect the temperature inside the mold. After casting is completed, the temperatures of the multiple temperature probes 213 are compared. If the temperatures shown by the multiple temperature probes 213 are the same, or the temperature difference is small, it proves that the casting effect of the mold is good. If the temperature difference of the multiple temperature probes 213 is large, it proves that the mold may be partially blocked due to impurities or poor flow of molten metal. It is necessary to check the casting channel to avoid the occurrence of too many defective products.
