Regular inspection and maintenance plans are implemented to ensure that the ejector structure is always in the best working condition.

[0050] The working principle of this utility model:

[0051] The ejector pin of the utility model is responsible for directly contacting and pushing the parts, while the ejector rod transmits the force of the ejector pin to the ejector plate, and the ejector plate is the support platform of the entire ejection structure. When the movable mold is closed, the ejection structure is in a contracted state and does not interfere with the molding process of the parts; when the mold is opened, the ejection structure quickly expands and pushes the upper tube parts out with accurately calculated force and speed. This ejection structure significantly improves the production qualification rate of the upper tube parts, reduces the scrap rate caused by appearance defects, and also helps to improve the automation level of the production line, reduce manual intervention, and reduce production costs.

[0052] Implementation case 1:

[0053] like Figure 1-11The ejection structure of the upper tube part of a floor fan shown in the figure includes an ejection mechanism, which includes a movable mold 1, a slider 2 and an ejector 3. The slider 2 is connected to the movable mold 1, the movable mold 1 is connected to the ejector 3, the slider 2 is connected to the upper tube 6, the movable mold 1 includes an ejection boss and an ejection channel, and the ejection boss is connected to the ejection channel.

[0054] The ejection mechanism also includes an ejector plate 4 and an ejector fixing plate 5, the ejector 3 is connected to the ejector plate 4, the ejector plate 4 is connected to the ejector fixing plate 5, the ejector plate 4 is provided with a through hole, the ejector 3 passes through the through hole and is connected to the ejector plate 4, the number of the through hole and the ejector 3 are both six, the ejection boss includes a front ejection boss 7 and a terminal ejection boss 8, the ejection channel includes a front ejection channel 9 and a terminal ejection channel 10, the front ejection boss 7 and the terminal ejection boss 8 are circular or T-shaped, the front ejection channel 9 is provided with a front ejection channel head 11, the terminal ejection channel 10 is provided with a terminal ejection channel head 16, the front The front end of the ejection channel head 11 is rectangular or elliptical, the rear end of the ejection channel head 12 is smoothly connected to the ejection channel, the lower end of the ejection boss is connected to the ejector pin 3, the top end of the upper tube 6 is provided with a thread, the upper tube 6 is provided with a side glue port 12, the side glue port 12 is connected to the ejection channel, the number of the upper tubes 6 is two, an upper double-sided ejection channel head 13 is provided between the side glue ports 12 of the two upper tubes 5, the upper double-sided ejection channel head 13 is connected to the main channel 14, a bottom double-sided ejection channel head 15 is provided between the bottoms of the two upper tubes 6, and the lower end of the bottom double-sided ejection channel head 15 is connected to the terminal ejection boss 8.

[0055] This embodiment innovates the upper tube part ejection system, creatively proposes an upper tube part ejection feature, cleverly arranges the ejector pin 3 at the ejection feature position, avoids arranging the ejector pin 3 on the part, solves the appearance defects of convex and concave bulges of the upper tube 6 part, and improves the product quality appearance and aesthetics.

[0056] The one-outlet-two-upper-tube parts mold made here is used to explain this utility model in detail. The ejection feature consists of three parts, namely, the ejection boss, the ejection channel and the ejection channel head. The ejection boss is generally cylindrical; the ejection channel can be designed to be circular or T-shaped; the ejection channel head is designed to be divided into two parts, the front section is designed to be rectangular or elliptical (the width direction dimension is 1.0mm~1.5mm; the length direction dimension is 3~5 times the width direction, and the front section is designed to be 3X1.0mm), the rear end is directly connected to the ejection channel, the ejection boss is mainly used to place the ejector pin 3, the ejection feature acts on the non-appearance surface of the product, and its small section is directly connected to the non-appearance area of ​​the product.

[0057] Since the side glue port 12 is used for glue injection, the product and the runner are connected together, so an ejection mechanism is cleverly set in the cold runner below the runner. Here, the main runner can be designed to be circular or T-shaped; the side glue port 12 can be designed to be rectangular or elliptical (the width dimension is 1.0mm~1.5mm; the length dimension is 3~5 times the width dimension, and here we design the size of the front section to be 3X1.0mm).

[0058] In order to ensure the balance of ejection, in addition to arranging ejector pins 3 in the area of ​​the non-appearance surface, ejector pins 3 should also be arranged at the other end of the non-outside surface. All ejector pins 3 are arranged on the ejection features. Regardless of whether the ejection position has convex or concave defects due to deformation of the ejector plate 4 or excessive injection pressure, these defects are all formed on the ejection boss, not on the product. Subsequently, these ejection features are cut off to obtain the molded product, which perfectly solves the convex and concave defects of the ejector pins on the product appearance.

[0059] Implementation case 2:

[0060] In this embodiment, Figure 1-11 The ejection structure of the upper tube part of a floor fan shown has the same technical means as the ejection structure of implementation case one.

[0061] The ejector structure is located inside the mold and is a mechanical device used to push the part out of the mold after the molding process is completed. In the production of the upper tube parts of floor fans, the design of the ejector structure is directly related to production efficiency and product quality. The first task in designing an effective ejector structure is to ensure that it can accurately and quickly remove the finished product from the mold. To do this, we must conduct an in-depth analysis of the existing ejector structure to identify possible problems, such as uneven ejection, excessive force causing product damage, or insufficient ejection force causing product retention.

[0062] Use the slender ejector pins to apply pressure to the product to release it from the mold. Attention should be paid to the distribution and number of ejector pins to avoid deformation or damage caused by uneven force. Regularly check the wear of the ejector structure and replace damaged parts in time to prevent production failures and ensure the continuity and stability of the production process.

[0063] The main functions of this utility model:

[0064] The utility model innovates the ejection structure of the upper tube parts of the floor fan, creatively proposes the ejection feature of the upper tube parts, cleverly arranges the ejector pin at the ejection position, avoids arranging the ejector pin on the parts, solves the appearance defects of convex and concave bulges of the upper tube parts, and improves the product quality appearance and aesthetics. This structure also reduces maintenance costs.

[0065] The ejector pin of the utility model is responsible for directly contacting and pushing the parts, while the ejector rod transmits the force of the ejector pin to the ejector plate, and the ejector plate is the support platform of the entire ejection structure. When the movable mold is closed, the ejection structure is in a contracted state and does not interfere with the molding process of the parts; when the mold is opened, the ejection structure quickly expands and pushes the upper tube parts out with accurately calculated force and speed. This ejection structure significantly improves the production qualification rate of the upper tube parts, reduces the scrap rate caused by appearance defects, and also helps to improve the automation level of the production line, reduce manual intervention, and reduce production costs.
