Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold structure. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts.

[0003] When the existing mold injection molding is used to produce indoor and outdoor bottom shells, multiple copper nuts must first be placed in the mold for in-mold injection molding. A 5-axis servo robot is used to place the copper nuts. The robot places the copper nuts, and the nuts are transferred from the vibration plate to the nut position fixture, then to the robot fixture, and then placed from the robot fixture into the mold. It takes three steps to complete the placement of the copper nuts. The copper nuts are easily lost during the process, resulting in less copper nuts on the bottom shell, and each bottom shell requires a robot to place the copper nuts, which makes the efficiency particularly low. Utility Model Content

[0004] To this end, the utility model provides a mold structure to solve the problem that when a robot places copper nuts, the nuts are transferred from a vibration plate to a nut position jig, then to a robot jig, and then placed from the robot jig into a mold. The copper nuts are easily dropped during the process, resulting in a shortage of copper nuts in the bottom shell and poor copper nuts. Each bottom shell requires a robot to place copper nuts, which is extremely inefficient.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold structure, including a mold body, a mold core is arranged inside the mold body, a plurality of copper nut slide grooves are opened on one side of the mold core, a bottom push plate is arranged inside the mold body, a top push plate is arranged on the top of the bottom push plate, a plurality of ejector pins are fixedly connected to the top of the bottom push plate, a plurality of copper nut guide sleeves are arranged on the top of the ejector pins, a plurality of copper nut guide sleeves are all penetrated through the mold core and are fixedly connected to the mold core, one end of a plurality of ejector pins respectively extends into the interior of a plurality of copper nut guide sleeves, cylinders are fixedly arranged on both sides of the mold body, unloading blocks are fixedly arranged on the output ends of the two cylinders, and one side of the two unloading blocks is in contact with the bottom push plate.

[0006] Preferably, a vibration plate is provided on one side of the mold core, one side of the vibration plate extends into the interior of the mold body, and a nut inlet is fixedly provided on one side of the vibration plate.

[0007] Preferably, guide pillars are fixedly provided at the four corners of the top of the mold body.

[0008] Preferably, a mold core glue surface is fixedly embedded on the top of the mold body.

[0009] Preferably, a copper nut opening is opened on one side of the plurality of copper nut guide sleeves, and the plurality of copper nut openings are respectively connected to the plurality of copper nut sliding grooves.

[0010] Preferably, the plurality of ejector pins all penetrate the top push plate.

[0011] Preferably, a plurality of return springs are fixedly connected to the top of the top push plate, and the top ends of the plurality of return springs are in contact with the bottom of the mold core.

[0012] The utility model embodiment has the following advantages:

[0013] The copper nut enters the mold from the vibration plate, and a copper nut slide groove is opened at the bottom of the mold core. The nut slides along the slide groove to the corresponding position of the nut. After the mold is closed, the cylinder drives the push plate to push the copper nut to the same level as the mold core glue surface before starting injection molding. Compared with the robot placing the nut, there is no need for a conversion process, which greatly reduces the copper nuts and improves the qualified rate. There is no need for a robot to place the nut, and it can be synchronized with the mold closing time, which can save the time of placing the copper nut and improve efficiency.
