Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning bracket manufacturing technology, specifically a precision mold for automotive air conditioning brackets. Background Technology

[0002] In the mold industry, various molds and tools are used to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. The automotive air conditioning compressor bracket needs to be produced and formed by corresponding molds.

[0003] A search revealed a die-casting mold for an automotive air conditioning compressor bracket with application number 202323317632.4. This device uses a syringe to inject lubricating oil through an injection hole onto a sponge sleeve. The sponge sleeve absorbs the lubricating oil, which then enters the sleeve body due to its tension. When the guide post passes through the sleeve body, the lubricating oil adsorbed from the sleeve body is applied to the outside of the guide post. The sponge sleeve continuously provides lubricating oil, reducing the lubricating oil application cycle. However, when lubricating the guide post, excess lubricating oil can only enter the sleeve body through the oil guide groove after the sponge is oversaturated (the lubricating oil inside the sponge remains absorbed when it is not saturated). This achieves the purpose of lubricating the guide post. When the guide post enters the sleeve body, excess lubricating oil inside the sleeve easily overflows from the gap between the guide post and the sleeve body (because the sponge is saturated and can no longer absorb excess lubricating oil), thus contaminating the mold. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a precision mold for an automotive air conditioning bracket to solve the technical problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision mold for an automotive air conditioning bracket, comprising an upper mold and a lower mold. The bottom of the upper mold is connected to a guide post. The outer surface and back of the lower mold are both connected to a maintenance plate by fixing bolts. The lower mold and the maintenance plate are both provided with positioning grooves and oil storage chambers. The positioning groove is provided with an oiling channel, and the oiling channel is connected to the oil storage chamber by an oil delivery channel. The oil storage chamber is connected to a piston by a spring, and the top of the piston is connected to a pressing column.

[0006] Furthermore, both the upper and lower molds have cavities inside, and the upper mold has an injection port at its top.

[0007] By adopting the above technical solution, during production, the upper mold drives the guide pillar into the positioning groove under the push of the hydraulic cylinder. The positioning groove and the guide pillar cooperate to limit the movement, so that the upper mold and the lower mold are closed. The material is injected into the cavity through the injection port. After the bracket is formed and cooled, it is demolded, thus completing the production.

[0008] Furthermore, the lower mold is internally connected to an ejector pin, which penetrates the lower mold and extends into the cavity.

[0009] By adopting the above technical solution, when the upper mold is moved upward, the output end of the hydraulic cylinder at the bottom of the lower mold drives the ejector pin to move upward, so that the ejector pin pushes the internal support of the cavity out of the cavity, making it convenient for the staff to remove the support, thereby speeding up production efficiency.

[0010] Furthermore, the extrusion column extends through the oil storage cavity, and the extrusion column is slidably connected to the positioning groove.

[0011] By adopting the above technical solution, under the drive of the upper mold, the bottom of the guide post contacts the extrusion post during the downward movement, causing the extrusion post to drive the piston downward. Under the extrusion of the piston, the lubricating oil inside the oil storage chamber is forced into the oil coating channel through the oil delivery channel to coat the outer surface of the guide post with oil.

[0012] Furthermore, the oiling channel is spiral-shaped.

[0013] By adopting the above technical solution, the contact area between the oiling channel and the guide post is increased by setting the oiling channel spirally, thereby increasing the oiling area on the outer surface of the guide post, avoiding dead corners in the coating, and thus enhancing the lubrication effect on the guide post.

[0014] Furthermore, the piston is slidably connected to the oil reservoir.

[0015] By adopting the above technical solution, the piston squeezes the spring under the drive of the extrusion column, and at the same time squeezes the lubricating oil in the oil storage chamber into the oil delivery channel. The oil delivery channel is then transported to the oil coating channel and the positioning groove to coat the outer surface of the guide column with oil, automatically providing lubricating oil to the guide column and reducing the lubricating oil coating cycle. When demolding, the piston returns to its original position under the action of the spring force, and at the same time, the lubricating oil in the positioning groove and the oil coating channel is sucked back into the oil storage chamber, avoiding the presence of lubricating oil in the positioning groove. This prevents the residual lubricating oil from being squeezed out of the positioning groove by the guide column during the next mold closing, thus avoiding soiling the mold table.

[0016] Furthermore, drain pipes are connected to both sides of the inspection plate, and the drain pipes penetrate the oil storage cavity.

[0017] By adopting the above technical solution, when it is necessary to inspect and maintain the inside of the positioning groove oil storage chamber, the staff first drains the lubricating oil inside the oil storage chamber through the drain pipe, and then loosens and removes the fixing bolts on the inspection plate, thereby cleaning and maintaining the inside of the positioning groove, oiling channel and oil delivery channel, so as to avoid dust and material residue generated during injection molding from mixing inside the lubricating oil, blocking the oil delivery channel and affecting the oiling effect on the guide column.

[0018] Furthermore, a sealing plug is connected to the outside of the sewage pipe, and the sewage pipe is threadedly connected to the sealing plug.

[0019] By adopting the above technical solution, when the lubricating oil needs to be replaced, the staff can loosen and remove the sealing plug to drain the lubricating oil from the drain pipe. After draining, a certain amount of new lubricating oil can be poured into the positioning groove to complete the replacement of the lubricating oil.

[0020] Furthermore, the sewage pipe is installed at an angle.

[0021] By adopting the above technical solution, the drain pipe is tilted, which makes it less likely for the material residue mixed in the lubricating oil to accumulate in the drain pipe, and at the same time speeds up the discharge speed of the lubricating oil from the oil storage chamber, thereby improving maintenance efficiency.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model is equipped with an oiling channel, an oil delivery channel, an extrusion column, a piston, a spring, and an oil storage cavity. During mold closing, under the pressure of the guide column, the extrusion column drives the piston to move downward, causing the piston to compress the spring. At the same time, the lubricating oil in the oil storage cavity is squeezed into the oil delivery channel, and then transported to the oiling channel and the positioning groove to coat the outer surface of the guide column with oil, automatically providing lubricating oil to the guide column and reducing the lubricating oil coating cycle. During demolding, under the action of the spring force, the piston returns to its original position, and at the same time, the lubricating oil in the positioning groove and the oiling channel is drawn back into the oil storage cavity, avoiding a large amount of lubricating oil remaining in the positioning groove. This prevents the residual lubricating oil from being squeezed out of the positioning groove by the guide column during the next mold closing, thus avoiding soiling the mold table.

[0024] 2. This utility model, by setting up an inspection plate, a drain pipe and a sealing plug, allows for the cleaning and maintenance of the positioning groove oil storage chamber when necessary. Workers first drain the lubricating oil from the storage chamber through the drain pipe, then loosen and remove the fixing bolts on the inspection plate. This allows for the cleaning and maintenance of the positioning groove, oiling channel and oil delivery channel, preventing dust and material residue generated during injection molding from mixing with the lubricating oil, blocking the oil delivery channel and affecting the oiling effect on the guide pillar.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1: A precision mold for an automotive air conditioning bracket, such as Figures 1-4 As shown, the mold includes an upper mold 1 and a lower mold 2. The bottom of the upper mold 1 is connected to a guide post 3. The outer surface and back of the lower mold 2 are connected to a maintenance plate 11 by fixing bolts 12. The lower mold 2 and the maintenance plate 11 are both provided with positioning grooves 4 and oil storage chambers 10. The positioning groove 4 is provided with an oiling channel 5, and the oiling channel 5 and the oil storage chamber 10 are connected by an oil delivery channel 9. The oil storage chamber 10 is connected to a piston 7 by a spring 8. The top of the piston 7 is connected to an extrusion column 6. The upper mold 1 and the lower mold 2 are both provided with cavities 14. The top of the upper mold 1 is provided with an injection port 13. During production, under the push of the hydraulic cylinder, the upper mold 1 drives the guide post 3 into the positioning groove 4. The positioning groove 4 and the guide post 3 cooperate to limit the movement, so that the upper mold 1 and the lower mold 2 are closed. The material is injected into the cavity 14 through the injection port 13. After the bracket is formed and cooled, it is demolded to complete the production.

[0033] See Figure 1 , Figure 2 and Figure 4 In the above embodiment, the lower mold 2 is connected to an ejector pin 15, and the ejector pin 15 penetrates the lower mold 2 into the cavity 14. When the upper mold 1 is moved upward, the output end of the hydraulic cylinder at the bottom of the lower mold 2 drives the ejector pin 15 to move upward, so that the ejector pin 15 pushes the bracket inside the cavity 14 out of the cavity 14, making it convenient for the staff to remove the bracket, thereby speeding up production efficiency.

[0034] See Figure 2 and Figure 4In the above embodiment, the extrusion column 6 penetrates the oil storage cavity 10 and is slidably connected to the positioning groove 4. Under the drive of the upper mold 1, the bottom of the guide column 3 contacts the extrusion column 6 during the downward movement, so that the extrusion column 6 drives the piston 7 to move downward. Under the extrusion of the piston 7, the lubricating oil inside the oil storage cavity 10 is pressed into the oil coating channel 5 through the oil delivery channel 9 to coat the outer surface of the guide column 3 with oil.

[0035] See Figure 2 , Figure 3 and Figure 4 In the above embodiment, the oiling channel 5 is spiral-shaped. By spirally setting the oiling channel 5, the contact area between it and the guide post 3 is increased, thereby increasing the oiling area on the outer surface of the guide post 3, avoiding dead corners in the coating, and thus enhancing the lubrication effect on the guide post 3.

[0036] See Figure 2 and Figure 4 In the above embodiment, the piston 7 is slidably connected to the oil storage cavity 10. Driven by the extrusion column 6, the piston 7 extrudes the spring 8 and simultaneously squeezes the lubricating oil in the oil storage cavity 10 into the oil delivery channel 9. The oil is then transported through the oil delivery channel 9 to the oil coating channel 5 and the positioning groove 4 to coat the outer surface of the guide column 3 with oil, automatically providing lubricating oil to the guide column 3 and reducing the lubricating oil coating cycle. When demolding, under the elastic force of the spring 8, the piston 7 returns to its original position, and at the same time, the lubricating oil in the positioning groove 4 and the oil coating channel 5 is drawn back into the oil storage cavity 10, avoiding the presence of lubricating oil residue in the positioning groove 4. This prevents the residual lubricating oil from being squeezed out of the positioning groove 4 by the guide column 3 during the next mold closing, thus avoiding soiling the mold table.

[0037] See Figures 1-4 In the above embodiment, drain pipes 16 are connected to both sides of the inspection plate 11, and the drain pipes 16 pass through the oil storage cavity 10. When it is necessary to inspect and maintain the inside of the oil storage cavity 10 of the positioning groove 4, the staff first drains the lubricating oil inside the oil storage cavity 10 through the drain pipes 16, and then loosens and removes the fixing bolts 12 on the inspection plate 11, so as to clean and maintain the inside of the positioning groove 4, the oiling channel 5 and the oil delivery channel 9, so as to avoid dust and material residue generated during injection molding from mixing inside the lubricating oil, blocking the oil delivery channel 9 and affecting the oiling effect on the guide column 3.

[0038] See Figures 1-4 In the above embodiment, a sealing plug 17 is connected to the outside of the drain pipe 16, and the drain pipe 16 is threadedly connected to the sealing plug 17. When the lubricating oil needs to be replaced, the operator loosens and removes the sealing plug 17, so that the lubricating oil to be replaced is discharged from the drain pipe 16. After the drain is cleaned, a certain amount of new lubricating oil is poured into the positioning groove 4 to complete the replacement of the lubricating oil.

[0039] Example 2: To accelerate the flow rate during lubricant replacement, Example 2 is an improvement upon Example 1. (See attached document for details.) Figure 3 The drain pipe 16 is inclined. By inclining the drain pipe 16, the material residue contained in the lubricating oil is less likely to accumulate in the drain pipe 16, and the speed of lubricating oil discharge from the oil storage chamber 10 is accelerated, thereby speeding up maintenance efficiency.

[0040] The implementation principle of this utility model is as follows: During production, the upper mold 1 is pushed by the output end of the hydraulic cylinder at the top, causing the upper mold 1 to drive the guide pillar 3 into the positioning groove 4. The positioning groove 4 and the guide pillar 3 cooperate to limit the movement, causing the upper mold 1 and the lower mold 2 to close. The material is injected into the cavity 14 through the injection port 13. After the support is formed and cooled, the upper mold 1 is moved upward, and the output end of the hydraulic cylinder at the bottom of the lower mold 2 drives the ejector pin 15 to move upward, pushing the support inside the cavity 14 out of the cavity 14, thus completing the production. During the production process, when the guide pillar 3 enters the positioning groove 4, the guide pillar 3 contacts the extrusion pillar 6, causing the extrusion pillar 6 to drive the piston 7 downward and compress the spring 8, while squeezing the lubricating oil in the oil storage chamber 10 into the cavity. Oil is transported through the oil delivery channel 9 to the oil coating channel 5 and the positioning groove 4 to coat the outer surface of the guide pillar 3 with oil. During demolding, the piston 7 returns to its original position under the action of the spring 8, and at the same time, the lubricating oil in the positioning groove 4 and the oil coating channel 5 is drawn back to the oil storage chamber 10. When it is necessary to inspect and maintain the inside of the oil storage chamber 10 of the positioning groove 4, the staff first drains the lubricating oil inside the oil storage chamber 10 through the drain pipe 16, then loosens and removes the fixing bolts 12 on the inspection plate 11, thereby cleaning and maintaining the inside of the positioning groove 4, the oil coating channel 5 and the oil delivery channel 9. After maintenance, the inspection plate 11 is fixed with the fixing bolts 12, and a certain amount of new lubricating oil is poured into the positioning groove 4.
