Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding machines, and in particular to a highly reliable intermittent multi-specification injection molding machine. Background Technology
[0002] The working principle of an injection molding machine is similar to that of a syringe. It uses the thrust of a screw to inject pre-plasticized molten plastic into a closed mold cavity. After solidification and shaping, the product is obtained. Injection molding is a cyclical process.
[0003] An injection molding machine typically consists of a base, a screw extruder, a mounting mold housing, an injection mold, and a drive cylinder. The injection mold is installed inside the mounting mold housing, and the screw extruder is slidably mounted on the base. Under the action of the drive cylinder, the output end of the screw extruder aligns with the feed end of the mounting mold on the mounting mold housing.
[0004] Furthermore, during operation, the screw extruder is positioned by a drive cylinder to ensure stable connection between the output end of the screw extruder and the feed port on the injection mold. However, the screw extruder generates vibration during operation, and it injects molten plastic into the injection mold through extrusion pressure. This creates a certain extrusion pressure between the screw extruder and the injection mold, which can lead to material leakage due to the discharge end of the screw extruder separating from the injection mold, thus presenting a certain defect. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Example 1
[0040] This utility model provides, for example Figure 1-3The invention described is a high-reliability intermittent multi-specification injection molding machine, comprising a support frame 1, a mounting mold housing 2, a screw extruder 3, a drive cylinder 4, and a locking assembly 5. The mounting mold housing 2 is fixedly mounted on the top of the support frame 1 and is used to mount the injection mold. An installation plate is slidably connected to the inside of the mounting mold housing 2 via a cylinder, allowing the mold to open and close during installation. This is prior art and will not be described in detail here. The screw extruder 3 is slidably mounted on the top of the support frame 1, and the drive cylinder 4 is also mounted on the top of the support frame 1. The output end of the drive cylinder 4 is connected to the screw extruder 3, allowing the drive cylinder 4 to drive the screw extruder 3 to slide on the support frame 1, thereby allowing the output end of the screw extruder 3 to engage or disengage with the injection mold inside the mounting mold housing 2. The locking assembly 5 is located on one side of the mounting mold housing 2 and is used to lock the output end of the screw extruder 3, ensuring the stability of the engagement between the output end of the screw extruder 3 and the inlet of the injection mold inside the mounting mold housing 2.
[0041] Furthermore, the locking assembly 5 includes a connecting rail 51 and a locking plate 52. The connecting rail 51 is fixedly connected to one side of the mounting mold housing 2. The outer side of the locking plate 52 is slidably engaged with the connecting rail 51, meaning the locking plate 52 can only slide up and down via the connecting rail 51. The locking plate 52 is slidably engaged with the outside of the output end of the screw extruder 3. The locking assembly 5 also includes a positioning block 53, a handle 55, and a positioning component 56. The positioning block 53 is fixedly connected to the outside of the output end of the screw extruder 3. The inner side of the locking plate 52 is engaged with the connecting rail 51. The wall has a groove 54 that matches the positioning block 53, so that the locking plate 52 can slide and engage with the positioning block 53 outside the output end of the screw extruder 3, thereby locking the output end of the screw extruder 3. The handle 55 is fixedly connected to the top of the locking plate 52. The handle 55 can drive the locking plate 52 to rise and slide, so that the locking plate 52 is separated from the output end of the screw extruder 3, so that the drive cylinder 4 can drive the screw extruder 3 to move. The positioning component 56 is set on the front of the locking plate 52 and the connecting rail 51.
[0042] Example 2
[0043] Based on Example 1, such as Figure 4 As shown, the positioning assembly 56 includes a connecting plate 561, a positioning rod 562, and a positioning groove 563. The connecting plate 561 is slidably disposed on one side of the locking plate 52, and the positioning rod 562 is fixedly connected to one side of the connecting plate 561. Two positioning grooves 563 are opened on one side of the connecting track 51. The outer wall of the positioning rod 562 is slidably engaged with the inner cavity of the positioning groove 563. When the positioning rod 562 on one side of the connecting plate 561 is engaged with the positioning groove 563 on the connecting track 51, the locking plate 52 is in a separated or engaged state with the output end of the screw extruder 3.
[0044] Furthermore, the positioning component 56 also includes a connecting rod 564, a limiting block 565, and a limiting spring 566. The outer wall of the connecting rod 564 is slidably inserted into the connecting plate 561. The limiting block 565 is fixedly connected to one end of the connecting rod 564. The limiting spring 566 is slidably sleeved on the outside of the connecting rod 564. The limiting spring 566 is located between the limiting block 565 and the connecting plate 561. The limiting spring 566 can provide the connecting plate 561 with an elastic force towards the connecting rail 51, thereby ensuring the stability of the connection between the connecting plate 561 and the positioning rod 562 and the connecting rail 51.
[0045] Furthermore, the positioning component 56 also includes a slot, a limiting plate 567, and a limiting rod 568. The slot is formed on the top of the locking plate 52, and the outer wall of the connecting rod 564 is slidably sleeved with the inner cavity of the slot. The limiting plate 567 is fixedly connected to the other end of the connecting rod 564. The locking plate 52 has a groove matching the limiting plate 567 on the side opposite to the connecting plate 561. One end of the limiting rod 568 is fixedly connected to the limiting plate 567, and the locking plate 52 has a limiting groove matching the limiting rod 568 on the side opposite to the connecting plate 561. Under the action of the limiting plate 567 and the limiting rod 568, the connecting rod 564 can maintain a stable locking state with the locking plate 52, so that the locking plate 52 slides away from the connecting track 51, and pushes the connecting rod 564 to slide relative to the locking plate 52, so that the limiting plate 567 and the limiting rod 568 separate from the locking plate 52. The connecting rod 564 can then be slidably removed from the slot, which facilitates its disassembly and maintenance.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
