Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and particularly to an injection mold structure that can make the undercut products more beautiful. Background Technique

[0002] An injection mold, also known as an injection molding mold, is a tool used for injection molding and is a commonly used mold in industrial production. Injection molding is a process of heating plastics, such as plastic particles or plastic fibers, to a molten state and then injecting the molten plastic into the mold through an injection molding machine, and cooling it to form a product with the required shape and size.

[0003] Conventional injection molds use a thimble structure to eject the injection molded part from the mold surface to achieve the demolding effect. However, such a structure will cause a certain degree of structural impact on the front surface of the injection molded part, thereby reducing the aesthetic degree of the surface of the injection molded part and affecting the product quality.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an injection mold structure that can make the undercut products more beautiful is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an injection mold structure that can make the undercut products more beautiful, so as to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an injection mold structure that can make the undercut products more beautiful, including a lower mold and a demolding mechanism. The top surface of the lower mold is provided with an injection molded part, and the bottom of the lower mold is connected with a mold base. Moreover, an adjusting frame is horizontally installed in the middle of the mold base. The demolding mechanisms are symmetrically installed at the left and right ends of the adjusting frame. The demolding mechanism includes a moving seat, a column, a support frame, a servo motor, a lead screw, and a shovel plate. A column is vertically installed on the top of the moving seat, and a support frame is installed on the top of the column. Moreover, a servo motor is vertically installed in the middle of the support frame, and the bottom power output end of the servo motor is installed with a lead screw through a coupling. At the same time, a shovel plate is connected to the surface of the lead screw.

[0007] Further, the mold base includes a base, a hydraulic column, and a support pile. Hydraulic columns are vertically installed at the four diagonal corners of the base, and a support pile is connected to the top of the hydraulic column.

[0008] Further, a groove matching the top surface structure of the support pile is opened on the bottom surface of the lower mold, and the support pile is embedded in the bottom of the lower mold.

[0009] Furthermore, the adjustment frame includes a track frame, a support column, a bidirectional screw and a drive motor. Support columns are installed at the bottom of the left and right ends of the track frame, and a bidirectional screw is installed horizontally in the middle of the track frame, and a drive motor is installed at one end of the bidirectional screw through a coupling.

[0010] Furthermore, the track frame is horizontally arranged in the middle of the base, and the track frame is installed on the top surface of the base in a sunken structure.

[0011] Furthermore, the track frame and the support column are fixedly connected, and the bidirectional lead screw is arranged in the inner center of the track frame in a sunken structure.

[0012] Furthermore, the movable seat is slidably connected to the track frame, and the movable seat is threadedly connected to the bidirectional lead screw.

[0013] Furthermore, the shovel plate is slidably connected and threadedly connected to the column and the screw rod respectively, and the movable seat, the column and the support frame are welded to each other.

[0014] The utility model provides an injection mold structure that can make undercut products more beautiful, and has the following beneficial effects:

[0015] 1. The utility model installs a servo motor in the middle of the support frame. When the servo motor is in operation, it drives the screw connected to the bottom to rotate vertically, so that the shovel plate connected to the surface can be translated up and down in the vertical direction. By using the above structure, the shovel plate can be horizontally inserted into the connection between the injection molded part and the lower mold, and through vertical translation, the injection molded part can be separated from the surface of the lower mold, and the shovel plate can be contacted from the bottom edge of the injection molded part, so as to reduce the contact surface of the structure as much as possible, avoid unnecessary impact on the surface of the injection molded part during the demolding process of the injection molded part, thereby ensuring product quality.

[0016] 2. In the utility model, since the entire demoulding mechanism is connected to the adjustment frame structure through the movable seat, when the driving motor is operated, it will drive the bidirectional lead screw connected thereto to rotate axially in the horizontal direction, so that the entire demoulding mechanism will translate left and right in the horizontal direction, so that the shovel plate can translate and be inserted at the edge of the junction between the injection molded part and the lower mold, so that the demoulding mechanism has good structural flexibility, and at the same time, it can avoid unnecessary structural interference caused by the demoulding mechanism when the lower mold and the upper mold are closed or separated. In addition, the upper and lower closing structure is adopted between the lower mold and the upper mold, so that the front of the injection molded part can avoid obvious parting lines as much as possible, thereby improving product quality.

Specific embodiments

[0022] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] Such as Figures 1 to 4As shown in the figure, an injection mold structure that can make the reverse-buckle product more beautiful, including a lower mold 1 and a demolding mechanism 5. The top surface of the lower mold 1 is provided with an injection molded part 2, and the bottom of the lower mold 1 is connected to a mold base 3. Moreover, an adjusting frame 4 is horizontally installed in the middle of the mold base 3. The demolding mechanisms 5 are symmetrically installed at the left and right ends of the adjusting frame 4. The demolding mechanism 5 includes a moving seat 501, a column 502, a support frame 503, a servo motor 504, a lead screw 505, and a stripping plate 506. A column 502 is vertically installed on the top of the moving seat 501, and a support frame 503 is installed on the top of the column 502. Moreover, a servo motor 504 is vertically installed in the middle of the support frame 503, and a lead screw 505 is installed at the bottom power output end of the servo motor 504 through a coupling. At the same time, a stripping plate 506 is connected to the surface of the lead screw 505. The moving seat 501 is slidably connected to the track frame 401, and the moving seat 501 is threadedly connected to the bidirectional lead screw 403. The stripping plate 506 is slidably connected and threadedly connected to the column 502 and the lead screw 505 respectively, and the moving seat 501, the column 502, and the support frame 503 are welded to each other. By installing a servo motor 504 in the middle of the support frame 503, when the servo motor 504 operates, it will drive the lead screw 505 connected to the bottom to rotate in the vertical axial direction. Thus, the stripping plate 506 connected to its surface can move up and down in the vertical direction. By using the above structure, the stripping plate 506 can be horizontally inserted into the connection between the injection molded part 2 and the lower mold 1, and through vertical translation, the injection molded part 2 can be separated from the surface of the lower mold 1.

[0024] The mold base 3 includes a base 301, a hydraulic column 302 and a support pile 303. The hydraulic columns 302 are vertically installed at the four diagonal positions of the base 301, and the top of the hydraulic column 302 is connected to the support pile 303. The bottom surface of the lower mold 1 is provided with a groove matching the top surface structure of the support pile 303, and the support pile 303 is embedded in the bottom of the lower mold 1. The adjustment frame 4 includes a track frame 401, a support column 402, a bidirectional lead screw 403 and a drive motor 404. The support columns 402 are installed at the bottom of the left and right ends of the track frame 401, and the bidirectional lead screw 403 is horizontally installed in the middle of the track frame 401, and one end of the bidirectional lead screw 403 is installed with a drive motor through a coupling. The driving motor 404 and the track frame 401 are horizontally mounted in the middle of the base 301, and the track frame 401 is installed on the top surface of the base 301 with a sunken structure. The track frame 401 is fixedly connected to the support column 402, and the bidirectional lead screw 403 is arranged in the inner center of the track frame 401 with a sunken structure. Since the entire demoulding mechanism 5 is connected to the adjustment frame 4 structure through the moving seat 501, when the driving motor 404 is operated, it will drive the bidirectional lead screw 403 connected thereto to rotate axially in the horizontal direction, so that the entire demoulding mechanism 5 will translate left and right in the horizontal direction, so that the shovel plate 506 can translate and be inserted at the edge of the junction of the injection molded part 2 and the lower mold 1.

[0025] In summary, if Figures 1 to 4 As shown, the injection mold structure that can make the undercut product more beautiful, when in use, firstly, after the lower mold 1 is structurally separated from the upper mold directly above, the adjustment frame 4 at the bottom of the mold base 3 and the demoulding mechanism 5 on the left and right sides of the mold base 3 operate synchronously, and the servo motor 504 installed on the top of the column 502 through the support frame 503 starts to operate, driving the screw rod 505 connected to the power output end at its bottom to start axial rotation in the vertical direction, so that the shovel plate 506 moves vertically along the surface of the column 502 and the screw rod 505 at the same time, and moves to a height relative to the bottom position of the injection molded part 2;

[0026] Then the driving motor 404 is operated at this time, and drives the bidirectional lead screw 403 connected to its power output end to rotate axially in the horizontal direction, so that the demolding mechanism 5 connected to the moving seat 501 is translated from the left and right sides to the sides of the injection molded part 2, and the shovel plate 506 is horizontally inserted into the edge of the connection between the injection molded part 2 and the lower mold 1. At this time, the hydraulic columns 302 around the base 301 will be synchronously extended and retracted to move the top lower mold 1 downward, further promoting the structural separation between the injection molded part 2 and the lower mold 1, thereby completing the demolding and minimizing the impact on the surface of the injection molded part 2 as much as possible.
