Description

Technical Field

[0001] This utility model relates to the field of demolding mold technology, specifically to an automatic demolding molding mold. Background Technology

[0002] In molding processes such as stamping, injection molding, and die casting, the mold release process directly affects production efficiency and product quality.

[0003] An existing patent (authorization announcement number: CN222511267U) discloses a molding die with automatic demolding capability. The key technical point of the solution is that by installing an automatic demolding mechanism, it is convenient to demold the product formed in the processing die. When the existing processing die stamps sheet metal parts into a specific shape, the sheet metal parts are difficult to demold when they are embedded in the processing die. Therefore, it is necessary to facilitate the demolding of the sheet metal parts in the processing die. First, the sealing top block is used to seal the top die groove to assist the stamping of the sheet metal parts. Then, the demolding electric rod works to drive the drive block to move into the drive slot. Then, the demolding motor works to drive the threaded screw to rotate, and the limit ring moves on the limit slide column. Then, the threaded slip ring moves on the threaded screw, which drives the sealing top block to move and eject the sheet metal parts in the processing die for easy demolding.

[0004] However, the above technical solutions still have certain defects. During the demolding process, the workpiece may remain in the mold cavity due to adhesion or vacuum adsorption, requiring manual intervention and reducing the degree of automation. In addition, during the stamping or injection molding process, material debris is easily left on the mold surface. Traditional cleaning methods require stopping the machine for manual cleaning, which affects production efficiency. Therefore, an automatic demolding molding mold is proposed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-5As shown, the automatic demolding forming mold includes a top plate 1, fixing rods 2 set at the four corners of the bottom of the top plate 1, a base plate 3 for supporting the mold at the bottom end of the fixing rods 2, a stamping assembly 4 for punching the mold on the top plate 1, a cleaning assembly 5 for cleaning the punch head on the base plate 3, and an ejection assembly 6 for ejecting the workpiece inside the mold at the top of the base plate 3.

[0031] In this embodiment, the mold is basically fixed and limited by the top plate 1, the fixing rod 2, and the bottom plate 3. At the same time, the stamping component 4 is set to stamp the workpiece. The cleaning component 5 is set to clean the stamping head 46 to prevent residual material from affecting subsequent forming. It is used to eject the workpiece from the mold after stamping, so as to realize automatic demolding.

[0032] In one embodiment, such as Figure 2 As shown, the stamping assembly 4 includes a drive cylinder 41 fixedly mounted on the top plate 1. The drive cylinder 41 drives a drive plate 42. A diagonal rod 43 is provided at the bottom of the drive plate 42, and a first spring 44 is also provided at the bottom of the drive plate 42, which is connected to the stamping head 46. A driven rod 45 is fixedly provided directly below the drive plate 42. The driven rod 45 is located at the top of the stamping head 46. Two sets of stamping heads 46 are symmetrically arranged and connected to the drive plate 42 through the first spring 44. The two ends of the diagonal rod 43 are respectively hinged to the drive plate 42 and the stamping head 46. When the piston rod of the drive cylinder 41 extends, it pushes the drive plate 42 down, and the diagonal rod 43 moves accordingly. Through the hinge point, it drives the two sets of stamping heads 46 to move towards each other. The driven rod 45 moves down with the drive plate 42 and finally contacts the stamping head 46 and applies downward pressure. The stamping head 46 maintains stable pressure under the combined action of the diagonal rod 43 and the spring, and stamps the workpiece.

[0033] In one embodiment, such as Figure 3 As shown, the cleaning component 5 includes a fixing plate 51 fixedly installed on the top of the base plate 3. Two sets of fixing plates 51 are mirror-arranged along the axial centerline of the base plate 3, and the two sets of fixing plates 51 are connected by a cleaning strip 52. The cleaning strip 52 is a vertical long plate, and the width of the cleaning strip 52 is adapted to the gap between the two sets of stamping heads 46. When the stamping head 46 returns to its starting position, its sidewall makes sliding contact with the cleaning strip 52, and the residual material is scraped off by the sharp edge of the cleaning strip 52. The scraping force is transmitted to the base plate 3 through the fixing plate 51 for absorption, keeping the stamping head 46 clean and avoiding affecting the quality of the next stamping.

[0034] In one embodiment, such as Figure 4 and Figure 5As shown, the ejection assembly 6 includes a bottom mold 61 fixedly installed on the top of the base plate 3. An air pump 62 is installed at the bottom of the bottom mold 61, and the air pump 62 is connected to a small hole inside the bottom mold. Fixed shells 63 are installed on both sides of the bottom mold 61. A second spring 64 is fixedly installed inside the fixed shell 63. A pushing block 65 is fixedly connected to the end of the second spring 64 away from the fixed shell 63. A connecting rod 67 is fixedly connected to the pushing block 65, and an ejection block 68 is fixedly installed at the end of the connecting rod 67 away from the pushing block 65. A through hole is opened on the bottom mold 61, and a guide rod 66 is installed inside the through hole. The guide rod 66 is located on the top of the pushing block 65 and at the bottom of the stamping assembly 4. Two sets of guide rods 66 are provided, and the two sets of guide rods 66 are vertically arranged in the force-bearing area of ​​the inclined surface at the top of the pushing block 65. The pushing block 65 has an inclined surface that cooperates with the guide rod 66. The bottom end of the 6-piece mold has rounded corners. When the guide rod 66 is pressed down, the ejector block 68 forms a conformal contact surface with the cavity of the bottom mold 61. During the stamping process, the guide rod 66 is pressed down by the drive plate 42, causing the guide rod 66 to move down accordingly. At this time, the push block 65 is pressed by the guide rod 66, and the rounded corner surface at the bottom end of the guide rod 66 contacts the inclined surface of the push block 65. At this time, the spring is compressed, and the ejector block 68 forms a conformal contact surface with the cavity of the bottom mold 61, which facilitates the forming of the workpiece. After the stamping is completed, the drive cylinder 41... The retraction causes the stamping head 46 to rise, the spring to stop being compressed, the push block 65 to rebound, the guide rod 66 to move upward, and the push block 65 to apply an outward pushing force to the connecting rod 67 and the ejector block 68, ejecting the formed workpiece from the side of the bottom mold 61 to complete the automatic demolding. At the same time, the air pump 62 blows air through the small holes inside the bottom mold 61 to further reduce the adhesion between the workpiece and the mold, ensuring smooth demolding, and can also blow away the stamping residue inside the bottom mold 61 for easy cleaning.

[0035] In one embodiment, such as Figure 4 As shown, the ejector block 68 is made of polyurethane rubber; through the elastic contact setting, it avoids sliding scratches and reduces machining marks on the workpiece surface when ejecting the workpiece.

[0036] The above embodiments disclose an automatic demolding forming mold. By setting a stamping assembly 4, the piston rod of the drive cylinder 41 extends, pushing the drive plate 42 downwards. The inclined rod 43 moves accordingly, driving two sets of stamping heads 46 to move towards each other through the hinge point. The driven rod 45 moves downwards with the drive plate 42 to stamp the workpiece. Simultaneously, when the stamping head 46 returns to its starting position, its sidewall makes sliding contact with the cleaning strip 52, and residual material is scraped off by the sharp edge of the cleaning strip 52. During the stamping process, the guide rod 66 is pressed down by the drive plate 42, and the rounded corner surface of the bottom end of the guide rod 66 contacts the inclined surface of the push block 65. The ejector block 68 forms a conformal contact surface with the cavity of the bottom mold 61, facilitating workpiece forming. After stamping is completed, the drive cylinder 41 retracts, driving the stamping head 46 upwards. The push block 65 applies an outward pushing force to the connecting rod 67 and the ejector block 68, ejecting the formed workpiece from the side of the bottom mold 61, completing the demolding.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
