Description

Technical Field

[0001] The invention relates to the technical field of material assembly, and in particular to a feeding device. Background Art

[0002] Metal insert injection molding is a method of pre-fixing metal inserts in the appropriate position in the mold, and then injecting plastic to form the mold. After the mold is opened, the inserts are tightly wrapped by the cooled and solidified plastic and buried in the product to obtain injection molded products with inserts such as threaded rings and electrodes. The combination of plastic insulation and metal conductivity can well meet the electrical safety performance requirements of the product. At the same time, the easy formability of plastics and the rigidity of metals not only provide new possibilities for the flexibility of product design, but also effectively avoid complicated secondary processes such as hot melting, welding and riveting, effectively shortening assembly time and cost. Therefore, metal insert injection molding is widely used in various industries such as electrical appliances, automobiles, medical, electronic products and connectors.

[0003] Limited by the mold structure and robot precision, most of the insert injection molding in the industry adopts the method of manually placing the insert. However, this method has the following problems: 1) The temperature of the inner mold of the injection mold is as high as 200-300℃. When reaching into the inner mold to place the insert, there is a great safety hazard of scalding the employee's hand; 2) Small inserts are difficult to take, and the insert holes reserved in the mold are small and delicate. When installing the insert, it is easy to make mistakes such as missing, falling, and not installing it in place; 3) The light inside the injection molding machine is not good. On-site employees need to hold a flashlight sideways to illuminate the space inside the machine to find the insert hole and confirm the insert placement effect. This makes the injection molding cycle long, the injection molding efficiency low, and even causes the injection molded products to be scrapped.

[0004] For example, the front shell components of most of the company's switching power supplies and household electrical appliances are made of PC plastic raw materials and metal electrode inserts. The size of the electrode insert is only 20mm*6.25mm*1.5mm, and the inner mold temperature is above 270℃.

The feeding hole 4 of the fixing part 1 is aligned with the mounting hole 6 of the mold 3. After the insert 5 is inserted into the mounting hole 6 of the mold 3, the side of the assembly block 10 close to the mold 3 can fit well with the surface of the mold 3, ensuring that the ejector pin 2 can accurately push the insert 5 in the feeding hole 4 into the mounting hole 6 on the mold 3.

The movable part 7 is pressed by the armrest 17, so that the elastic component 16 sleeved on the positioning column 9 is compressed, thereby changing the distance between the movable part 7 and the fixed part 1, driving the ejector pin 2 fixed on the movable part 7 to move in a direction close to the fixed part 1, and the insert 5 can be pushed into the mounting hole 6 in the mold 3 at one time.

[0076] When starting to load materials, with the help of the diagonal end of the active part 7 of the loading device, place the loading device on its back on the horizontal table near the right hand side of the injection molding machine staff, align the loading hole 4 on the loading device, and quickly and accurately load the prepared insert 5 into the reserved loading hole 4 on the loading device. Then hold the handrail 17 of the loading device tightly. The material of the handrail 17 here is preferably aluminum alloy with plastic wrapped outside to make it lighter. Lift the loading device sideways, align the positioning column 9 on the loading device with the positioning hole 15 on the mold 3, and gently push it to complete the precise positioning, which is labor-saving and smooth. At this time, apply a slight force on the handrail 17 to compress the elastic component 16 on the positioning column 9, so that the active part 7 slowly approaches the fixed part 1, and the ejector 2 is driven by the active part 7 to eject the insert 5, so that the insert 5 in the hole of the insert 5 can be smoothly sent into the mounting hole 6 of the high-temperature mold 3 of the injection molding machine. After all the inserts 5 are fed into the mounting holes 6 of the mold 3, stop applying force to the armrest 17, and the movable part 7 of the feeding device will automatically rebound to the original position through the elastic component 16. The feeding device can be easily taken out and the next round of operation can be started.

[0077] In this embodiment, the fixed part 1 is provided with a plurality of feeding holes 4 on one side close to the mold 3, and inserts 5 are provided in the plurality of feeding holes 4. The ejector pin 2 is inserted into the feeding hole 4 from the side of the fixed part 1 away from the mold 3, and the ejector pin 2 abuts against the insert 5, and the ejector pin 2 is used to push the insert 5 into the mounting hole 6 of the mold 3. The feeding device can be directly placed on a normal temperature workbench, and then the insert 5 is inserted into the feeding hole 4 of the feeding device, and then the feeding device is picked up, and the positioning column 9 of the feeding device is aligned with the positioning hole 15 in the high temperature mold 3 and inserted, so as to complete the precise matching of the feeding device and the mold 3. Then, the movable part 7 is pressed by the handrail 17, so that the movable part 7 is pressed down and close to the fixed part 1, and the positioning column 9 fixed on the fixed part 1 and the linear bearing 11 fixed on the movable part 7 are guided, and the elastic component 16 sleeved on the positioning column 9 is adjusted synchronously, so that the insert 5 can be automatically and smoothly pushed into the mounting hole 6 of the mold 3, avoiding problems such as effort and jamming. With the aid of the feeding device, not only the potential safety hazard of employees being scalded during high-temperature operations is effectively avoided, but also the installation of several inserts 5 can be completed with one click, which greatly improves the efficiency and accuracy of feeding.
