Description

Technical Field

[0001] The present application relates to the field of molds, and in particular to an injection mold with upper mold positioning. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping and other methods.

[0003] Referring to the Chinese utility model patent with patent number CN218196601U, a hot-pressing injection mold is disclosed, including a cylinder plate, a hot runner plate, a mother mold plate, a male mold plate and an injection piece, wherein a flow channel for material flow is arranged in the injection piece, a first heat insulation plate is arranged between the hot runner plate and the cylinder plate, and a second heat insulation plate is arranged between the hot runner plate and the mother mold plate. The hot-pressing injection mold reduces the heat transfer from the hot runner plate to the cylinder plate and the mother mold plate by placing the first heat insulation plate and the second heat insulation plate, which not only retains the temperature of the hot runner plate itself and reduces the heat loss, but also prevents the temperature of the cylinder plate from rising, thereby affecting the normal operation of the cylinder plate and the mother mold plate, thereby avoiding affecting the injection molding effect.

[0004] In actual use, hot pressing injection molds often need to be connected to wires. When the driving mechanism is connected to the movable mold part of the injection mold, it is easy to contact with the wires, making the connection between the driving mechanism and the movable mold inconvenient, which needs to be improved. Utility Model Content

[0005] In order to facilitate the connection between the movable mold and the external driving mechanism, the present application provides an injection mold that facilitates the positioning of the movable mold.

[0006] The present application provides an injection mold that facilitates the positioning of a movable mold, which adopts the following technical solution:

[0008] By adopting the above technical solution, in actual use, the movable mold needs to be connected and positioned with the driving mechanism. Since the wiring part is connected to the wires, there is a situation where the driving mechanism clamps the movable mold to clamp the wires, which is inconvenient. Therefore, a connecting part is provided, and the distance between the end of the positioning protrusion 2 of the connecting part away from the mounting groove and the connecting part is greater than the distance between the end of the positioning protrusion 1 away from the mounting groove and the connecting part. The driving mechanism is limited to move further downward by the positioning protrusion 2, thereby reducing the situation where the driving mechanism clamps the wires, making it more convenient for the driving mechanism to clamp the movable mold and facilitating the use of the mold body.

[0010] By adopting the above technical solution, a limit spring and a limit block are provided, and the limit block is pressed against the top plate to make the connection between the connecting part and the movable mold more stable, reduce the situation where the connecting part is separated from the movable mold, and make the overall use more stable.

[0012] By adopting the above technical solution, an inclined surface is set. When the inclined surface contacts the side wall of the top plate, the inclined surface causes the limit block to be separated toward the bottom of the limit groove, and the limit block moves toward the direction close to the bottom of the limit groove. In this way, the connection between the connecting part and the top plate is facilitated.

[0013] Optionally, the connecting part is provided with a sliding hole, the sliding hole passes through the connecting part to the limiting groove, and the limiting block is provided with a sliding rod at one end close to the bottom of the limiting groove. The sliding rod slides in the sliding hole, the sliding direction of the sliding rod is a vertical direction, and the end of the sliding rod away from the limiting block protrudes from the end face of the connecting part.

[0014] By adopting the above technical solution, a sliding rod is provided, which is used to control the movement of the limit block, thereby facilitating the subsequent separation of the connecting part and the top plate, reducing the situation in which the sliding block presses against the end surface of the top plate when the connecting part is separated from the top plate, causing wear marks on the top plate, and improving the overall service life.

[0018] By adopting the above technical solution, a fixed protrusion is set, and the fixed protrusion is embedded in the positioning plate, which reduces the separation of the positioning plate and the movable mold, reduces the situation of the wires falling out of the wire groove, and makes the overall use more stable.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A connecting part is provided, and the distance between the end of the positioning protrusion 2 of the connecting part away from the mounting groove and the connecting part is greater than the distance between the end of the positioning protrusion 1 away from the mounting groove and the connecting part. The positioning protrusion 2 limits the driving mechanism from further moving downward, thereby reducing the situation where the driving mechanism clamps the wire, making it more convenient for the driving mechanism to clamp the movable mold, and facilitating the use of the mold body;
