Horizontal injection molding machine with calibration structure

Abstract

The application discloses a horizontal injection molding machine with a calibration structure, comprising a machine body, a injection mechanism arranged on one side of the top surface of the machine body, and an open-close mold mechanism arranged on the other side of the top surface of the machine body. The calibration assembly box of the application can automatically adjust the stroke path of the injection cylinder by cooperating with the docking assembly. When the injection cylinder moves towards the open-close mold mechanism, the conical ring enters the conical port, so that the floating table continuously adjusts the position in the lateral and vertical directions. When the conical ring completely enters the conical port, the nozzle and the injection hole are located on the same horizontal line. Then, the injection cylinder continues to move to insert the nozzle into the injection hole, so that automatic calibration is realized. The calibration is convenient. In this way, automatic calibration can be performed every time, the nozzle is prevented from being extruded, the service life of the nozzle is prolonged, and the molten plastic can enter the mold from the central position during injection, so that the injection quality is ensured.

Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, specifically to a horizontal injection molding machine with a calibration structure. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric, with horizontal injection molding machines being the most common type. In this type, the mold closing section and injection section are on the same horizontal centerline, and the mold opens horizontally. The machine is low-profile, making it easy to operate and maintain. For example, Chinese utility model patent CN207724705U discloses a horizontal injection molding machine, belonging to the field of injection molding machines. The machine frame is equipped with a fixed ejector rod, a movable mold plate, and a fixed mold plate connected by four tie rods, as well as an injection mechanism communicating with the fixed mold plate. The fixed and movable mold plates have cooling chambers filled with heat transfer medium along the mold core outline, and cooling water coils are also provided within the cooling chambers. The outer wall of the injection mechanism has a jacket, and the upper part of the injection mechanism is connected to the discharge port of the feeding device. However, current horizontal injection molding machines have the following drawbacks: Although the mold closing section and the injection section are on the same horizontal center line, there will still be some error. When the injection section moves into the mold closing section, the nozzle is prone to misalignment when it is inserted into the injection channel of the mold closing section. This causes the nozzle to be squeezed by the injection channel. The stroke calibration of the injection section is very troublesome. In order to improve work efficiency, it is not possible to calibrate it every time. Instead, a calibration is performed only once every long period of time. This makes the nozzle easily squeezed by the injection channel during use, resulting in a generally short lifespan for injection nozzles, which is not conducive to use.

[0003] Therefore, we propose a horizontal injection molding machine with a calibration structure to solve the above problems. Summary of the Invention

Channel 248 enters the inclined channel 247, which connects to the check cavity 245 near one end of the screw 219. The inclined channel 248 connects to the middle of the check cavity 245. When the screw 219 rotates to feed, the molten liquid at the end flows into the inclined channel 247. The ball 246 is forced to move to the front end, so that the molten liquid can enter the front end of the injection barrel 27 through the inclined channel 248. When the screw 219 moves horizontally to inject molten liquid, when the molten liquid at the end enters the check cavity 245, the ball 246 is forced to enter the other end of the check cavity 245, which can block the inclined channel 247 and prevent the molten liquid from flowing back.

[0029] Please see Figure 1-13This is the third embodiment of the present invention, based on the above two embodiments. When the present invention is used, the moving stage 23 moves toward the mold opening and closing mechanism 3, the conical ring 285 enters the conical opening 392, completing the position calibration of the floating stage 25. Then, the two locking components 29 lock the position of the floating stage 25. Simultaneously, the moving stage 23 continues to move with the injection cylinder 27 until the nozzle 210 is inserted into the injection hole 333. At the same time, the second hydraulic cylinder 349 drives the force plate 35 to move, causing the moving module 311 and the fixed module 312 to close the mold. During material feeding... Plastic material is added at port 249. Drive motor 212 drives screw 219 to rotate, conveying the plastic material. Heated by heating wire 217, the plastic material melts into a liquid state. The molten liquid enters the end of injection cylinder 27 through conical head 220. Then, drive motor 212 stops, and first cylinder 215 moves motor frame 211, causing screw 219 to move towards mold opening / closing mechanism 3, injecting the molten liquid into the mold. After completion, the mold is cooled by cooling coils. Then, second cylinder 349 drives force plate 35 in the opposite direction. The movement causes the moving module 311 to move away from the fixed module 312. When the force-bearing rod 327 is pushed by the pressure column 328, the ejector rod 329 moves relative to the moving module 311, pushing the molded plastic product off the moving module 311 and into the discharge port 348. The calibration component 28 and the docking component 39 of this invention cooperate to automatically adjust the stroke path of the injection cylinder 27. When the injection cylinder 27 moves toward the mold opening and closing mechanism 3, the conical ring 285 enters the conical opening 392, causing the floating platform 25 to continuously move to both sides. The nozzle 210 is aligned with the injection hole 333 by adjusting its position vertically. When the conical ring 285 is fully inserted into the conical opening 392, the nozzle 210 and the injection hole 333 are aligned at the same horizontal level. Then, the injection cylinder 27 continues to move to insert the nozzle 210 into the injection hole 333, achieving automatic calibration. Calibration is convenient, and automatic calibration can be performed every time, avoiding the nozzle 210 being subjected to extrusion pressure, increasing the service life of the nozzle 210, and ensuring that the molten plastic can enter the mold from the center position during injection, thus ensuring injection quality.
