Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and more specifically, to an ejection device for a door panel with a female mold adsorption molding die. Background Technology

[0002] Vacuum forming molds refer to the molds used in vacuum forming production. The lowest cost molds are plaster molds, followed by electroplated copper molds, and the most expensive are aluminum molds. The molds have small holes drilled in them to allow for vacuum adsorption of heated hard plastic sheets, forming the vacuum-formed product.

[0003] Existing adsorption molding molds used for processing door panels require manual removal of the molded workpiece from the inside of the mold after adsorption molding. Due to the large vacuum adsorption force, the workpiece adheres tightly to the mold, making manual removal inconvenient and resulting in low removal efficiency, which in turn affects the processing efficiency of the workpiece. Therefore, we propose an ejection device for a door panel female mold adsorption molding mold to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an ejector device for a door panel with a female mold adsorption forming mold. It can reset the ejector rod through the elastic force of the spring, thereby ejecting the formed workpiece located inside the forming mold body, facilitating manual removal of the workpiece, and thus improving the processing efficiency of the workpiece.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An ejection device for a door panel with a female mold adsorption molding die includes a female mold base, a vacuum connector disposed at the bottom of the female mold base, a molding die body installed inside the female mold base, and an air extraction hole opened on the surface of the molding die body. The surface of the molding die body is also provided with a recessed hole, and a screw hole is provided at the bottom end of the recessed hole.

[0009] A threaded post is screwed into the threaded hole. A sleeve is integrally formed at the top of the threaded post. Guide grooves are symmetrically opened on the inner wall of the sleeve at the axial position. A baffle is movably connected between the guide grooves. A guide block that slides and connects with the guide groove is welded to the edge of the baffle. A top rod is welded to the upper surface of the baffle.

[0010] A spring is installed below the baffle;

[0011] By placing the workpiece for mounting on the door panel inside the molding mold body, and using a vacuum connector in conjunction with an air extraction hole to create a vacuum, a vacuum is formed between the workpiece and the molding mold body, thereby adsorbing and shaping the workpiece with the molding mold body.

[0012] During the adsorption molding process, the workpiece is pushed to the inside of the housing by the guide block set at the edge of the baffle and the guide groove. The spring is compressed and deformed. After the vacuum is stopped at the vacuum joint, the elastic force of the spring resets the push rod, thereby ejecting the molded workpiece located inside the molding mold body. This makes it easier to remove the workpiece manually and improves the processing efficiency of the workpiece.

[0013] Furthermore, the top of the top rod is provided with a groove, and the groove is set in a straight line structure. By using a tool such as a flathead screwdriver to abut against the groove and rotate it, the threaded post is disengaged from the screw hole, which facilitates the disassembly and replacement of the casing.

[0014] Furthermore, an anti-slip washer is provided at the junction of the threaded post and the sleeve, and the anti-slip washer is in close contact with the bottom wall of the recess. By using the anti-slip washer to increase the friction between the sleeve and the recess, the threaded post can be effectively prevented from loosening inside the threaded hole.

[0015] Furthermore, one end of the spring is connected to the baffle, and the other end of the spring is connected to the bottom wall of the housing. The elastic force of the spring resets the push rod, thereby ejecting the molded workpiece located inside the molding die body, facilitating manual removal of the workpiece and improving the processing efficiency of the workpiece.

[0016] Furthermore, a limiting part is provided at the port of the casing, and the inner diameter of the limiting part is smaller than the outer diameter of the baffle. Under the elastic force of the spring, the baffle abuts against the limiting part, thereby limiting the top rod and preventing it from detaching from the casing.

[0017] Furthermore, the sleeve and the concave hole form an embedded structure, ensuring the flatness of the workpiece after adsorption and molding.

[0018] Furthermore, the sum of the axial lengths of the baffle and the push rod is less than the axial length of the inner side of the sleeve, and the push rod is pressed into the inner side of the sleeve, ensuring the flatness of the part where it meets the workpiece.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this scheme, during the adsorption molding process, the workpiece is pushed to the inner side of the housing by the guide block set at the edge of the baffle and the guide groove, and the spring is compressed and deformed. After the vacuum is stopped at the vacuum joint, the elastic force of the spring is used to reset the push rod, thereby ejecting the molded workpiece located inside the molding mold body, which is convenient for manual removal and thus improves the processing efficiency of the workpiece.

[0022] (2) In this solution, by using a tool such as a flathead screwdriver to abut against the groove and rotate it, the threaded post is disengaged from the screw hole, making it convenient to disassemble and replace the casing. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1-6An ejection device for a door panel with a female mold adsorption molding die includes a female mold base 1, a vacuum connector 2 located at the bottom of the female mold base 1, a molding die body 3 installed inside the female mold base 1, and an air extraction hole 4 opened on the surface of the molding die body 3. The surface of the molding die body 3 is also provided with a recessed hole 5, and a screw hole 6 is provided at the bottom end of the recessed hole 5.

[0034] A threaded post 7 is screwed into the screw hole 6. A sleeve 8 is integrally formed at the top of the threaded post 7. Guide grooves 9 are symmetrically opened on the inner wall of the sleeve 8 at the axial position. A baffle 11 is movably connected between the guide grooves 9. A guide block 12 that slides and connects with the guide groove 9 is welded to the edge of the baffle 11. A top rod 13 is welded to the upper surface of the baffle 11.

[0035] A spring 10 is installed below the baffle 11;

[0036] It should be noted that when the ejection device of the door panel mounting negative mold adsorption molding die is used, the workpiece to be mounted on the door panel is placed inside the molding die body 3, and the vacuum connector 2 is used in conjunction with the air extraction hole 4 to create a vacuum in the space between the workpiece and the molding die body 3, thereby adsorbing and molding the workpiece with the molding die body 3.

[0037] During the adsorption molding process, the workpiece slides through the guide block 12 set at the edge of the baffle 11 in conjunction with the guide groove 9, thereby squeezing the ejector rod 13 to the inside of the housing 8 and compressing and deforming the spring 10. After the vacuuming at the vacuum joint 2 stops, the ejector rod 13 is reset by the elastic force of the spring 10, thereby ejecting the molded workpiece located inside the molding mold body 3, which is convenient for manual removal and thus improves the processing efficiency of the workpiece.

[0038] like Figure 1 , Figure 4 , Figure 6 As shown, a groove 14 is provided at the top of the top rod 13, and the groove 14 is arranged in a straight line.

[0039] It should be noted that by using a tool such as a flathead screwdriver to abut against and rotate the groove 14, the threaded post 7 can be disengaged from the screw hole 6, making it convenient to disassemble and replace the sleeve 8.

[0040] like Figure 4 , Figure 5 As shown, an anti-slip washer 15 is fitted at the part where the threaded column 7 and the sleeve 8 are joined, and the anti-slip washer 15 is tightly fitted to the bottom wall of the recess 5.

[0041] It should be noted that by using the anti-slip washer 15 to increase the friction between the sleeve 8 and the concave hole 5, the threaded post 7 can be effectively prevented from loosening inside the threaded hole 6.

[0042] like Figure 1 , Figure 5 , Figure 6 As shown, the sleeve 8 and the concave hole 5 form an embedded structure, and the sum of the axial lengths of the baffle 11 and the push rod 13 is less than the axial length of the inner side of the sleeve 8.

[0043] It should be noted that the sleeve 8 and the concave hole 5 form an embedded structure, and the push rod 13 is pressed into the inside of the sleeve 8, ensuring the flatness of the part where it meets the workpiece.

[0044] like Figure 6 As shown, one end of the spring 10 is connected to the baffle 11, and the other end of the spring 10 is connected to the bottom wall of the housing 8. A limiting part is provided at the port of the housing 8, and the inner diameter of the limiting part is smaller than the outer diameter of the baffle 11.

[0045] It should be noted that under the elastic force of the spring 10, the baffle 11 abuts against the limiting part, thereby limiting the push rod 13 and preventing it from detaching from the sleeve 8.

[0046] In use: By placing the workpiece for mounting on the door panel inside the molding mold body 3, and using the vacuum connector 2 in conjunction with the air extraction hole 4 to perform vacuuming, a vacuum is formed in the space between the workpiece and the molding mold body 3, thereby adsorbing and shaping the workpiece in conjunction with the molding mold body 3.

[0047] During the adsorption molding process, the workpiece slides through the guide block 12 set at the edge of the baffle 11 in conjunction with the guide groove 9, thereby squeezing the ejector rod 13 to the inside of the housing 8 and compressing and deforming the spring 10. After the vacuuming at the vacuum joint 2 stops, the ejector rod 13 is reset by the elastic force of the spring 10, thereby ejecting the molded workpiece located inside the molding die body 3.

[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
