An automatic inserting and picking device for micro-injection molding

technical field

The utility model relates to an automatic device for embedding inserts and taking out molding workpieces in the process of micro-injection molding, and belongs to the technical field of micro-injection molding inserts and extractions.

Background technique

The micro-injection molding process is basically the same as the traditional injection molding process. The plastic particles are sent from the hopper of the injection molding machine into the heated barrel. Through the nozzle at the front of the barrel. It is poured into the cavity of the closed mold through the gating system of the mold, and the product with a certain shape is formed after holding pressure, cooling and demoulding.

With the rapid development of micro/nano science and technology, miniaturization and precision have become the trend of product design and development. Miniaturization of products and equipment can not only achieve functional integration, but also greatly reduce material and energy consumption and improve space utilization. rate etc. With the development of miniaturization of products and equipment, the requirements for the complexity of micro-miniature parts, material diversity, processing accuracy, production efficiency, etc. are getting higher and higher; With an annual growth rate of 20%, the market demand for tiny parts has effectively promoted the development of tiny parts manufacturing technology.

In the insert molding process, the injection molding machine is usually only a part of the overall system. Inserts usually require first pick-up. A vibrating table is used to accomplish this task. The end-of-arm tooling (EOAT) then places the insert into the mold, usually with the aid of a pre-positioning device. The existing embedding and extraction can be done manually, which is time-consuming and laborious, and the efficiency is not high. It can also be completed by injection molding manipulators, but most injection molding machine manipulators are relatively simple in type and complex in structure, and most of them are used for picking up parts, and the market price is relatively high.

Detailed ways

As shown in FIG. 1 , the micro-injection molding automatic insertion and extraction device of the present utility model mainly includes an insert container 4 , an insert container translation mechanism 2 , an insert pallet 11 , a pallet translation mechanism 3 and a lifting mechanism 1 . The shape and size of the insert container 10 correspond to the cavity 7 on the parting surface 8 of the fixed mold 9 in the mould. The insert container 4 is located above the insert pallet 10 and is connected with the insert container translation mechanism 2. The insert container translation mechanism 2 moves the insert container 4 horizontally between the movable mold 6 and the fixed mold 9 on the injection molding machine. The insert pallet 10 is arranged on the pallet translation mechanism 3, and the pallet translation mechanism 3 horizontally moves the insert pallet 10 between the movable mold 6 and the fixed mold 9 on the injection molding machine. Both the insert container translation mechanism 2 and the pallet translation mechanism 3 are arranged on the lifting mechanism 1, and are driven up and down by the lifting mechanism 1, and the heights of both are adjusted at the same time. The translational mechanism 2 of the insert container and the translational mechanism 3 of the pallet can adopt any existing mechanism to move the object horizontally, such as various electronically controlled translation stages, which belong to the known technology. Lifting mechanism 1 can adopt any existing mechanism that makes objects lift up and down, such as various hydraulic lifting platforms, which also belong to known technology.

The working process of the above-mentioned device is as follows:

①In the case of inserts, firstly, according to the characteristics of each insert, the placement posture of the inserts is adjusted through the insert alignment device, so that the inserts are automatically oriented and sorted, and then the inserts are passed through the conveying mechanism (or manually) according to the specified posture Placed in the insert container 4 , the insert container 4 is above the insert pallet 10 at this time, and the inserts in the insert container 4 are supported by the insert pallet 10 .

② Adjust the height of the insert container translation mechanism 2 and the pallet translation mechanism 3 through the lifting mechanism 1, so that the insert pallet 10 and the parting surface 8 of the mold are kept on the same level.

③The insert container 4 and the insert pallet 10 are synchronously driven by the insert container translation mechanism 2 and the pallet translation mechanism 3 to move linearly, and they reach the placement opening of the mold cavity 7 together, and then the insert pallet 10 moves back, The upper insert container 4 remains stationary, so that the insert falls into the cavity 7 of the fixed mold 8 .

④The insert container 10 is moved back and reset under the drive of the insert container translation mechanism 2 .

⑤ Clamp the movable mold 5 and the fixed mold 8, and inject the insert through the nozzle 5 on the injection molding machine to complete the embedding of the insert.

⑥Injection molding is completed, the mold is opened, and the injected workpiece is ejected to the parting surface.

⑦The insert pallet 11 is driven by the pallet translation mechanism 3 to reach the parting surface again, and the injected product is pushed away from the parting surface, and then the insert pallet 10 moves back to its original position and returns to the upper and lower combination with the insert container 4 state, complete the removal of the formed workpiece.

⑧Repeat the above operation to carry out the next cycle of inserting and picking to realize the automation of inserting and picking.
