Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, and in particular to an injection hook molding machine. Background Technology

[0002] The product needs to be processed into an injection hook shape. The current common processing method is one-piece injection molding using a mold. However, this method is too slow, not conducive to mass production, and the mold size is too large. There is a need for a simple structure and high production efficiency equipment. Therefore, an injection hook molding machine is disclosed.

[0003] Publication No. CN221339539U discloses an injection hook forming machine, including a frame with rollers movably connected to it. Multiple annular baffles and multiple annular mold pieces are sleeved on the rollers, with the annular mold pieces and annular baffles arranged alternately. Multiple hook-shaped notches are provided on the annular mold pieces, and the hook-shaped notches form hook-shaped grooves with two adjacent annular baffles. This invention achieves rapid production of injection hooks by using the alternating arrangement of multiple annular mold pieces and annular baffles to form hook-shaped grooves. Hot-melt sheets are inserted between adjacent rollers and embedded into the hook-shaped grooves. The rotation of the rollers transfers the formed injection hooks and simultaneously drives the hot-melt sheets for a new round of injection hook processing, further improving production efficiency.

[0004] Existing mold forming machines are inconvenient to demold from the injection hook during use, resulting in poor performance. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing mold forming machines, such as the inconvenience of demolding the injection hook and poor performance, and to propose an injection hook forming machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An injection molding machine for hooks, comprising:

[0008] The base has a controller on its outer side and a housing on its top. Two covers are symmetrically mounted on the outer side of the housing via hinges, and each cover has a transparent plate.

[0009] An extruder is located inside a housing. Two electric cylinders are fixedly installed on the inner wall of the housing. A fixing plate is installed on the output shaft of the electric cylinders. The extruder is fixedly installed on the fixing plate and has an extrusion port connected to it.

[0010] The mold mechanism is located inside the housing and is connected to the extrusion port.

[0011] Preferably, the outer side of the housing has a movable hole, and the extruder is movably connected to the movable hole.

[0012] Preferably, the mold mechanism includes a moving mold and a fixed mold. The moving mold has a mold groove, and the fixed mold is fixedly installed on the inner wall of the outer shell. The fixed mold has a mold core, which cooperates with the mold groove.

[0013] Preferably, two receiving slots are formed on the inner wall of the model slot, and a demolding module is seamlessly slidably connected inside the two receiving slots. A demolding rod is fixedly installed on the left side of each of the two demolding modules, and a compression pad is fixedly installed on the outer end of each of the two demolding rods.

[0014] Preferably, a return spring is sleeved on the outer side of each of the two demolding rods. One end of the return spring is fixedly installed with the extrusion pad, and the other end of the return spring is fixedly installed with the moving mold. Four support rods are fixedly installed on the outer side of the moving mold, and all four support rods are fixedly installed with the fixing plate.

[0015] Preferably, a vertical plate is fixedly installed on the top inner wall of the outer shell, and four circular holes are opened on the vertical plate. The four support rods are slidably connected to the inner walls of the four circular holes.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] In this design, two electric cylinders drive the fixed plate to move backward, causing the moving mold to separate from the fixed mold. The moving mold drives two extrusion pads to contact the vertical plate, and the vertical plate extrudes the two extrusion pads. The two extrusion pads push two demolding rods to move, and the two demolding rods push the demolding module to move. The two demolding modules push out the molding material, thus achieving the purpose of automatic demolding.

[0018] In this solution, two electric cylinders drive the moving mold and the fixed mold to continue to be used. Through the elastic force of the return spring, the detached mold is reset and enters the receiving groove.

[0019] This invention has a simple structure, is easy to operate, can automatically demold, and has good performance. Attached Figure Description
