Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding nozzle overflow guiding device. Background Art

[0002] The injection molding machine is a precision manufacturing equipment, which is divided into many types. Its working process basically follows the following process: the mold is placed in the injection molding machine, the injection molding machine closes the mold, and the mold remains closed during the injection molding process under the action of the clamp. The plastic in the shape of particles or pellets is fed into the injection molding machine, and the injection molding machine heats the plastic until it becomes liquid. The injection molding machine nozzle then injects the melted plastic into the mold. At this time, the mold cavity is filled with plastic liquid. After cooling, these liquids will form solid products. The shape is determined by the designed mold. Finally, the cooled product is taken out of the machine to obtain the finished part. According to this process cycle, a steady stream of products can be injection molded;

[0003] Before the injection molding machine injects products, it is necessary to add injection materials first, and then form plastic liquid by heating. Before the plastic liquid is injected into the mold for product production, it is necessary to check the plasticization of the plastic. Only when the plasticization of the plastic is qualified can the product be injected cyclically. When checking the plasticization of the plastic, it is necessary to separate the injection nozzle from the front mold locking plate, take out the plastic liquid injected into the front mold locking plate, and check its plasticization degree. The general method is to drag the plastic liquid out of the front mold locking plate through a rod. When there is more plastic liquid, it is easy to draw or the plastic liquid drips directly on the body of the injection molding machine, which is not convenient for cleaning, especially for some injection molding machines with high wiring density on the body. In addition, when the injection molding machine needs to change materials, overflow will drip on the body of the injection molding machine during the separation of the injection nozzle from the locking plate. For this reason, it is necessary to set a guiding device that can guide the plastic liquid out. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-4 In the embodiment of the utility model, an injection nozzle overflow guiding device is adopted, which includes a locking plate 10 and a guide component 20 installed on the locking plate 10, and the locking plate 10 is provided with an injection nozzle connecting port 11, and the locking plate 10 is arranged on the injection molding machine and docked with the injection nozzle of the injection molding machine. The front mold of the mold is installed on the other side of the locking plate 10, and after the injection nozzle docks with the locking plate 10, the injection material is injected into the mold through the locking plate 10 to complete the injection molding operation. The utility model arranges the guide component 20 below the injection nozzle connecting port 11, and the guide component 20 includes an overflow platform 21 and a guide plate 22 integrally formed on one side of the overflow platform 21 and inclined downward, and a blocking edge 23 is formed on the edge of the overflow platform 21, and the blocking edge 23 extends to the lower end of the guide plate 22 along the side of the guide plate 22 close to the locking plate 10.

[0027] Through this arrangement, when monitoring the plasticizing of the plastic or when the injection nozzle is separated from the locking plate 10 and overflow occurs, the injection material can be caught by the overflow table 21 below it, and some injection material in a flowing state can be guided to flow out to a side of the injection molding machine body through the guide plate 22, so as to facilitate the operator to check and clean it. Therefore, through this simple arrangement, the overflow generated by the injection molding machine can be effectively guided, thereby preventing the overflow from dripping on the injection molding machine and causing it to be difficult to clean.

[0028] By setting the blocking edge 23 and setting the blocking edge 23 at the position of the guide component 20 close to the locking template 10, the overflow on the guide component 20 can be blocked and will not flow onto the locking template 10. The blocking edge 23 is not set on the side of the guide plate 22 away from the locking template 10, so that the overflow is easy to remove.

[0029] See also Figure 1-3 In this embodiment, a fixing hole 24 is provided on the blocking edge 23 of the overflow platform 21 close to the locking template 10, and a threaded hole 12 is provided on the injection nozzle connection port 11. The guide component 20 is screwed to the locking template 10 by connecting the screws of the fixing hole 24 with the threaded hole 12. In this way, the overflow platform 21 can be firmly and reliably attached to the locking template 10. In terms of setting, it is preferred that both the fixing hole 24 and the threaded hole 12 are provided with two horizontally distributed ones, and the fixing hole 24 is extended in the vertical direction to form a long hole structure, which is convenient for fine-tuning its height.

[0030] See also Figure 1-2 In this embodiment, a flange portion 13 is formed on the injection nozzle connection port 11, and the guide component 20 is fixedly connected to the flange portion 13. The upper edge of the blocking edge 23 connected to the flange portion 13 is coaxial with the flange portion 13 and has an arc-shaped structure, so that the overall fit is tighter, and the arc-shaped structure can improve the strength of the overflow table 21 so that it will not bend and deform.

[0031] See also Figure 1-3 In this embodiment, the overflow table 21 is tilted toward the guide plate 22, and the lower edge of the blocking edge 23 is compensated based on the tilt of the overflow table 21, so that the upper edge of the blocking edge 23 remains horizontal. Through this setting, the injection molding material in the flowing state can be better guided, so that the flowing injection molding material can flow to the corresponding position along the overflow table 21 and the guide plate 22 after overflowing.

[0032] See also Figure 1 , Figure 2 and Figure 4In this embodiment, a reinforcement portion 14 is extended and formed on the locking template 10 at the lower portion corresponding to the flange portion 13, and a support frame 30 is connected to the reinforcement portion 14. The overflow table 21 is carried on the support frame 30. Through this arrangement, the strength of the overflow plate can be improved, so that the overflow plate will not be deformed by the overflowed injection molding material; wherein, the support frame 30 includes a fixing bolt 31 fixedly connected to the reinforcement portion 14, a hinge seat 32 rotatably connected to the fixing bolt 31, and a support block 33 hinged to the hinge seat 32. The overflow table 21 is carried on the support block 33. Through this arrangement, the support frame 30 can be fine-tuned so that it can fit closely to the inclined overflow table 21.

[0033] See also Figure 3 In this embodiment, a dragging notch 25 is provided at the corner position of the lower end of the guide plate 22 corresponding to one side of the blocking edge 23, which is convenient for dragging out the plastic. That is, when the injection molding material flows along the guide component 20 to the lower end position of the guide plate 22 and accumulates, the operator can use a rod-shaped tool to drag the injection molding material out from the rear along the position of the dragging notch 25, thereby facilitating the cleaning of the overflowed injection molding material.
