Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a hot runner injection structure with side-entry capability. Background Technology

[0002] When performing injection molding, if the plastic parts to be processed have complex shapes, especially those with multiple intricate details, slender parts, or those that are difficult to inject through the traditional top or bottom, a side-injection hot runner injection structure is used. By injecting through the side, the plastic material can flow into the mold cavity accurately and evenly, avoiding incomplete filling or mold filling difficulties caused by the position of the traditional injection port.

[0003] When using this device, first select the appropriate hot runner injection head according to production needs, then install the appropriate hot runner injection head inside the mold, and then the molten plastic material enters the hot runner system through the injection machine. After being kept in a molten state through the heating pipe, it enters the side injection port, so that the plastic material flows evenly along the runner into the mold cavity. After the plastic material cools down, the mold opens and the plastic part is successfully demolded.

[0004] Considering that hot runner injection heads need to be protected with dust covers before placement or installation to prevent dust or external contaminants from adhering to the injection head surface and entering the injection molding process, causing uneven product surfaces or defects, the current method of installing dust covers typically involves using two sets of semi-circular dust covers to cover multiple injection heads and then fixing the two sets of dust covers together with bolts. This process is not only cumbersome due to the design requirements of the two sets of semi-circular dust covers, requiring multiple dust covers to be combined and then fixed with bolts, but also increases operation time and labor costs when installing and removing dust covers for multiple hot runner injection heads. Therefore, a side-injection hot runner injection structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a side-injection hot runner dispensing structure, which aims to improve the existing technology where hot runner dispensing heads need to be protected with dust covers before installation to prevent dust and contaminants from adhering to the surface of the injection head and affecting product quality. However, the installation method of using two sets of semi-circular dust covers and fixing them with bolts is cumbersome, especially when installing multiple dispensing heads, which increases operation time and labor costs, making the installation and disassembly process more complicated.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot runner glue injection structure with side-injection capability, comprising a glue injection head, a ring A connected to the right side of the outer surface of the glue injection head, a handle B slidably connected to the right side of the outer surface of the ring A, an arc-shaped plate fixedly connected to the left side of the outer surface of the handle B, a base on the outer surface of the arc-shaped plate slidably connected to the inner surface of the ring A via a spring, a snap-fit ​​component B fixedly connected to the left side of the outer surface of the arc-shaped plate, a ring B connected to the left side of the outer surface of the glue injection head, a snap-fit ​​component A fixedly connected to the right side of the outer surface of the ring B, the right side of the outer surface of the ring B and the left side of the outer surface of the ring A being in contact and connected, the outer surface of the snap-fit ​​component A engaging with the outer surface of the snap-fit ​​component B, and a fixing component provided at the top of the outer surface of the glue injection head.

[0007] As a further description of the above technical solution:

The bottom of the outer surface of the clamping disc is in contact with the top of the outer surface of the dispensing head. The bottom of the outer surface of the clamping disc is in contact with the top of the outer surface of the spray nozzle. A bolt is slidably connected through the inner surface of the clamping disc. The bottom of the outer surface of the bolt is threadedly connected to the top of the outer surface of the dispensing head.

[0009] As a further description of the above technical solution:

[0010] A protective component A is inserted into the left side of the inner surface of the ring A, and a screw is slidably connected through the outer surface of the protective component A. The right side of the outer surface of the screw is threadedly connected to the left side of the inner surface of the ring A.

[0011] As a further description of the above technical solution:

[0012] A protective component B is inserted into the right side of the inner surface of the ring A. The outer surface of the screw penetrates and slides through the inner surface of the protective component B. The rear end of the outer surface of the screw is threadedly connected to the right side of the inner surface of the ring A.

[0013] As a further description of the above technical solution:

[0014] The inner surface of the ring B is also fitted with protective components A and B.

[0015] As a further description of the above technical solution:

[0016] The outer surface of the protective component A is fixedly connected to a positioning block, and the outer surface of the positioning block is inserted into the inner surface of the ring A and the inner surface of the ring B.

[0017] As a further description of the above technical solution:

[0018] The handle B is provided in two sets, and the handle A is fixedly connected to the left side of the outer surface of the ring body B.

[0019] As a further description of the above technical solution:

[0020] One end of the spring is fixedly connected to the inner surface of the ring A, and the other end of the spring is fixedly connected to the outer surface of the arc-shaped plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by providing an arc-shaped plate, a snap-fit ​​component A and a snap-fit ​​component B, when the two sets of rings are combined together, the snap-fit ​​component A and the snap-fit ​​component B snap into each other to fix the two sets of rings together. When the fixation is released, the two sets of handles B are squeezed to release the fixation of the front and rear ends of the rings simultaneously, thereby simplifying the installation process and improving the efficiency of installation and disassembly.

[0023] 2. In this utility model, by making the protective components detachable, when a single set of protective components is damaged, the damaged protective components can be replaced by unscrewing the screws, without having to replace the entire system or multiple components, thus greatly reducing maintenance costs.

An arc-shaped plate 13 is fixedly connected to the left side of the outer surface of the handle B4, allowing the arc-shaped plate 13 to move together when the handle B4 moves vertically. The base of the outer surface of the arc-shaped plate 13 is slidably connected to the inner surface of the ring A2 via a spring 12, ensuring that the arc-shaped plate 13 maintains an outward movement even without external force. A snap-fit ​​component B14 is fixedly connected to the left side of the outer surface of the arc-shaped plate 13, allowing the snap-fit ​​component B14 to move together when the arc-shaped plate 13 moves vertically. A ring B8 is connected to the left side of the outer surface of the glue head 1, allowing the ring B8 to fit against the left side of the outer surface of the glue head 1. A snap-fit ​​component A6 is fixedly connected to the right side of the outer surface of the ring B8, allowing the snap-fit ​​component A6 to move along with the ring B8 when it moves, and fixing the ring B8 in a designated position when the snap-fit ​​component A6 is in a fixed state. The right side of the outer surface of the ring B8 is connected to the left side of the outer surface of the ring A2, allowing the ring B8 to be spliced ​​and combined with the ring A2, completely covering the spray nozzle 7 on the glue head 1. The outer surface of the snap-fit ​​component A6 snaps into the outer surface of the snap-fit ​​component B14, allowing the snap-fit ​​component A6 to be spliced ​​and combined with the snap-fit ​​component B14, allowing the two sets of rings to be spliced ​​and combined together. A fixing component is provided at the top of the outer surface of the glue head 1, which allows the spray nozzle 7 to be fixed to the inner surface of the glue head 1.

[0032] Reference Figure 1 - Figure 2The fixing assembly includes a clamping disc 15 and a bolt 16. A spray nozzle 7 is snapped onto the top of the inner surface of the dispensing head 1, allowing the spray nozzle 7 to be fixed to the top of the inner surface of the dispensing head 1. The bottom of the outer surface of the clamping disc 15 is in contact with the top of the outer surface of the dispensing head 1, allowing the clamping disc 15 to be placed on the top of the outer surface of the dispensing head 1. The bottom of the outer surface of the clamping disc 15 is in contact with the top of the outer surface of the spray nozzle 7, allowing the spray nozzle 7 to be prevented from moving vertically when snapped onto the top of the inner surface of the dispensing head 15. A bolt 16 is slidably connected through the inner surface of the clamping disc 15, allowing the bolt 16 to move vertically along the inner surface of the clamping disc 15. The bottom of the outer surface of the bolt 16 is threadedly connected to the top of the outer surface of the dispensing head 1, allowing the clamping disc 15 to be fixed to the top of the outer surface of the dispensing head 1 through the threaded connection between the bottom of the outer surface of the bolt 16 and the top of the outer surface of the dispensing head 1.

[0033] Reference Figure 2 - Figure 4 A protective component A5 is inserted into the left side of the inner surface of ring A2, allowing the protective component A5 to move laterally with the left side of the inner surface of ring A2. A screw 10 is slidably connected through the outer surface of the protective component A5, allowing the screw 10 to move laterally along the inner surface of the protective component A5. The right side of the outer surface of the screw 10 is threadedly connected to the left side of the inner surface of ring A2, allowing the protective component A5 to be fixed inside ring A2 through the threaded connection between the screw 10 and the left side of the inner surface of ring A2. A protective component B9 is inserted into the right side of the inner surface of ring A2, allowing the protective component B9 to move laterally with the right side of the inner surface of ring A2. The outer surface of the screw 10 is slidably connected through the inner surface of the protective component B9, allowing the screw 10 to move laterally along the threaded connection between the screw 10 and the inner surface of the protective component B9. The inner surface of the protective component B9 moves laterally. The rear end of the outer surface of the screw 10 is threadedly connected to the right side of the inner surface of the ring A2, so that the protective component B9 can be fixed inside the ring A2 by the threaded connection between the screw 10 and the right side of the inner surface of the ring A2. The inner surface of the ring B8 is also inserted with the protective components A5 and B9, so that when the ring B8 is attached to the dispensing head 1, the dispensing head 7 can also be protected by the internal protective components. The outer surface of the protective component A5 is fixedly connected with the positioning block 11, so that the protective component A5 can move together when it moves. The outer surface of the positioning block 11 is inserted into the inner surface of the ring A2 and the inner surface of the ring B8, so that the protective component A5 can be fixed in the designated position by the positioning block 11.

[0034] Reference Figure 1 - Figure 2 , Figure 4The handle B4 is provided in two sets, so that when the two sets of handles B4 are squeezed, the four sets of latching pieces A6 and four sets of latching pieces B14 can be simultaneously released. The handle A3 is fixedly connected to the left side of the outer surface of the ring B8, so that it is more convenient to pick up the ring B8. One end of the spring 12 is fixedly connected to the inner surface of the ring A2, and the other end of the spring 12 is fixedly connected to the outer surface of the arc plate 13. After the latching piece A6 squeezes the inclined surface of the latching piece B14, the latching piece B14 can drive the arc plate 13 to move outward through the spring 12, so as to latch with the latching piece A6.

[0035] Working principle: When using the device, align the two sets of rings with the spray nozzles 7 that need protection, and then squeeze the two sets of rings inward. This causes the snap-fit ​​A6 on the right side of ring B8 to snap into the snap-fit ​​B14 on the inner surface of ring A2, fixing the two sets of rings together. Furthermore, the protective parts A5 and B9 inside the two sets of rings are inserted into the multiple spray nozzles 7 on the dispensing head 1, providing protection for the spray nozzles 7. When it is necessary to release the two sets of rings, simply squeeze the two sets of handles B4 on ring A2 simultaneously. This causes the two sets of arc plates 13 to move inward, which in turn moves the snap-fit ​​B14 inward, releasing the snap-fit ​​A6 and thus releasing the locking effect of the two sets of rings.

[0036] When replacing the protective component, simply unscrew the screw 10 on the corresponding protective component to remove and replace it.

[0037] 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.
