Description

Technical Field

[0001] This invention relates to the field of injection molding machine production technology, and more specifically to a fast preheating servo injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines heat plastics and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity. Mechanical keyboards are a type of keyboard. Structurally, each key on a mechanical keyboard has an individual switch to control its closure. This switch is also called a "switch". According to the classification of microswitches, mechanical keyboards can be divided into traditional brown switches, blue switches, white switches, black switches, as well as red switches and optical switches. Because each key is composed of an independent microswitch, the key tactile feedback is strong, thus producing a special feel suitable for gaming and entertainment. Therefore, they are usually considered relatively expensive high-end gaming peripherals.

[0003] The vast majority of mechanical keyboard shells are made of plastic, and their production process requires injection molding. This involves heating the raw material, injecting it into a custom mold, and then cooling it to achieve the production goal.

[0004] Because mechanical keyboards require multiple key connection slots on their outer walls, they need to be thoroughly cooled during production. To ensure production efficiency, the finished outer casing often sticks to the mold, making it difficult to remove manually. Special tools are required for removal, causing significant inconvenience. Furthermore, when the ambient temperature is low, the injection molding material cannot reach the desired temperature quickly enough, requiring the material to be heated to the working temperature, resulting in a significant time consumption and greatly reducing the production efficiency of the injection molding machine, thus presenting certain limitations.

[0005] Therefore, a fast preheating servo injection molding machine was designed. Summary of the Invention

[0006] The main technical problem solved by this invention is to provide a fast preheating servo injection molding machine that can solve the problems of existing injection molding machines being unable to adapt to different working temperatures and the adhesion between the injection molded parts and the mold.

[0010] Furthermore, a hydraulic rod is installed on the outer wall of the protective shell, and one end of the hydraulic rod is fixedly connected to the outer wall of the push plate. Several sets of telescopic rods are fixed between the push plate and the mold closing die. Furthermore, the inner rotating cylinder is rotatably connected to the inner wall of the mold closing die, and the mold closing die has a rotating groove matching the inner rotating cylinder.

[0013] Furthermore, a protective door is slidably mounted on the top of the injection molding machine body on one side of the protective housing, and an opening and closing groove matching the protective door is slidably mounted on the top of the injection molding machine body on the other side of the protective door.

[0018] The beneficial effects of the rapid preheating servo injection molding machine of the present invention are as follows:

[0019] By activating the hydraulic rod, the push plate can be slid, which in turn can cause the mold closing mold to fit into the fixed mold. At this time, the telescopic rod can be compressed. Then, with the cooperation of the connecting rod, inner slider, inner groove, inner rotating cylinder, outer rotating cylinder, outer slider, and outer groove, and with the connection between the extension rod and the push cylinder, the extension rod and the push cylinder can slide in opposite directions, which can make the push rod eject the injection molded product. At the same time, with the cooperation of the slide plate, slide column, sealing plate, square slider, and guide groove, the two sets of sealing plates can retract into the mold closing mold, thereby facilitating the removal of the injection molded product.

[0020] By activating the hydraulic rod reset, when removing the injection-molded product, the extension column can slide under the cooperation of the telescopic rod and the mold closing mold, which in turn drives the push rod connected to it to rotate around the position in contact with the rocker arm. This allows the rocker arm to rotate around the position in contact with the protective door, which in turn drives the receiving plate to rotate to one side of the mold closing mold, so that the injection-molded product inside can be collected, thus facilitating the collection and removal of the injection-molded product.

[0021] By starting the water pump, the heat transfer fluid inside the heating pipe can be drawn into the heat energy connection pipe, and then into the spiral tube. This preheats the injection molding material to a constant temperature, and then further heats it, greatly improving the production efficiency of the injection molding machine.

The spiral tube 410, the heat energy connecting pipe 420 and the heating pipe 440 are all filled with heat-conducting liquid. When the injection molding machine body 110 starts to work and inject, the injection material can be fed in through the feed inlet 150. At this time, the water pump 430 is started, which can draw the heat-conducting liquid inside the heating pipe 440 into the heat energy connecting pipe 420, and then into the spiral tube 410. This can heat the outer wall of the feed inlet 150, and then preheat the injection material to a constant temperature, and then further heat it, which greatly improves the production efficiency of the injection molding machine.

[0045] The working principle of this device is as follows: When the injection molding machine body 110 starts to inject the mold, the injection material can be fed in through the feed port 150. At this time, the water pump 430 is started, and with the cooperation of the rapid preheating component 400, the heat circulation effect can be achieved, thereby preheating the injection material to a constant temperature. The injection heating tube 160 can heat the material. At this time, the hydraulic rod is started, and with the connection of the push plate 210 and the telescopic rod 220, the mold closing mold 230 and the fixed mold 240 can be fitted together. Then, with the mutual cooperation of the connecting rod 231, the inner slider 2311, the inner slide groove 2312, the inner rotating cylinder 232, the outer rotating cylinder 233, the outer slider 2331, and the outer slide groove 2332, the device can achieve the following: When the mold is closed, and with the extension rod 234 connected to the push cylinder 236, the extension rod 234 and the push cylinder 236 can slide in opposite directions. At the same time, with the cooperation of the slide plate 237, slide column 2371, sealing plate 238, square slider 239 and guide groove 2391, the two sets of sealing plates 238 can retract into the mold 230, allowing the push rod 235 to eject the injection molded product, thereby facilitating the removal of the injection molded product. Meanwhile, with the cooperation of the material receiving and collecting assembly 300, the material receiving plate 320 can be rotated to one side of the mold 230 to collect the injection molded product inside, thus facilitating the collection and removal of the injection molded product.
