Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for automotive parts. Background Technology

[0002] Injection molding is a method of plastic molding and processing. It involves placing granular plastic in a barrel, heating it to melt and plasticize it, and then applying pressure with a plunger or screw to inject the flowing material from the nozzle at the end of the barrel into a mold of the desired shape to fill the mold cavity. In the production of automotive parts, injection molds are commonly used tools.

[0003] In existing injection molds, after the workpiece is formed, it is inconvenient for workers to remove the workpiece from inside the mold, which affects production efficiency. During production, material will adhere to the upper mold, and workers often need to remove multiple fixing bolts to remove the upper mold, which is quite inconvenient. This utility model device can demold the workpiece, making it convenient for workers to remove the internal workpiece and disassemble the upper mold, which is convenient for workers to disassemble and clean. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold for automotive parts, which solves the problems of inconvenient removal of workpieces from inside the mold, which affects production efficiency, and the inconvenience of removing multiple fixing bolts from the upper mold during production, where materials adhere to the upper mold.

[0005] To achieve the above objectives, an injection mold for automotive parts is provided, comprising: a base plate, an upper mold, and a lower mold. A stripper plate is slidably connected inside the lower mold, and two inclined blocks are fixedly connected to the lower surface of the stripper plate. A motor is fixedly connected inside the lower mold, and a bidirectional screw is fixedly connected to the output end of the motor. The end of the bidirectional screw away from the motor is rotatably connected to the inner wall of the lower mold. Two threaded blocks are threadedly connected to the outside of the bidirectional screw, and the upper surface of the threaded blocks is slidably connected to the lower surface of the inclined blocks, which facilitates the removal of internal workpieces by the operator and improves work efficiency.

[0006] The upper surface of the base plate is fixedly connected to a mounting bracket, the lower surface of the mounting bracket is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a first mounting plate, the upper surface of the upper mold is fixedly connected to a second mounting plate, the lower surface of the first mounting plate is in contact with the upper surface of the second mounting plate, two inserts are fixedly connected to the lower surface of the first mounting plate, the outer surfaces of the two inserts are slidably connected to the inside of the second mounting plate, a fitting plate is fitted into the side of the second mounting plate, two limiting rods are fixedly connected to the side of the fitting plate, the side surfaces of the limiting rods are slidably connected to the inside of the inserts, a fixing bolt is threaded into the inside of the second mounting plate, a rotating ring is rotatably connected to the outside of the fixing bolt, and the side surface of the rotating ring is fixedly connected to the inner wall of the fitting plate, which facilitates the disassembly and cleaning of the upper mold by the staff and increases the convenience of the device.

[0007] According to the aforementioned injection mold for automotive parts, the lower surface of the threaded block is slidably connected to the bottom of the lower mold, and the side surface of the inclined block is slidably connected to the inner wall of the lower mold. The lower mold can prevent the threaded block from rotating with the bidirectional screw, thus facilitating the movement of the threaded block.

[0008] According to the aforementioned injection mold for automotive parts, a limiting post is threadedly connected to the upper surface of the upper mold. The limiting post is T-shaped and can limit the movement of the upper mold by means of the limiting post.

[0009] According to the aforementioned injection mold for automotive parts, the upper surface of the upper mold has a through-hole, and the lower surface of the base plate is fixedly connected and supported at all four corners, allowing for convenient injection molding through the injection hole.

[0010] According to the aforementioned injection mold for automotive parts, a positioning post is fixedly connected to the lower surface of the lower mold, and the side surface of the positioning post is slidably connected to the inside of the base plate, thereby facilitating the installation of the lower mold.

[0011] According to the aforementioned automotive parts injection mold, the two insert blocks are symmetrically arranged, and the two limiting rods are symmetrically arranged, which facilitates the insertion of the rods into the insert blocks and facilitates the installation and fixation of the upper mold.

[0012] According to the aforementioned injection mold for automotive parts, the inner wall of the base plate is slidably connected to the side surface of the lower mold, which facilitates the installation of the lower mold.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] The motor drives the bidirectional screw to rotate, which in turn drives the threaded blocks to move in opposite directions. The inclined surface on the threaded block cooperates with the inclined surface of the inclined block. When the threaded block moves laterally, it facilitates the up and down movement of the inclined block and the ejector plate, which helps the workers to remove the internal workpiece and improves work efficiency.

[0015] By rotating the fixing bolt, the rotating ring and the insert plate can be moved, making it easy to pull out the limiting rod, release the limiting rod from the insert block, and facilitate the disassembly and cleaning of the upper mold by the staff, thus increasing the convenience of the device.
