Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to a demolding mechanism for an oxygen humidification bottle injection molding machine. Background Technology

[0002] Oxygen humidification bottles are a type of rehabilitation equipment and ward nursing consumable, mainly used in medical central oxygen supply systems for emergency oxygen supply and oxygen inhalation for hypoxic patients. They are essential equipment for oxygen therapy in hospital emergency rooms and wards. Existing equipment for injection molding oxygen humidification bottles has the disadvantage of inconvenient demolding, and the bottle structure is easily damaged during the demolding process, so it needs to be improved. Utility Model Content

[0003] To facilitate the demolding of oxygen humidification bottles, this application provides a demolding mechanism for an oxygen humidification bottle injection molding machine.

[0004] The demolding mechanism for an oxygen humidification bottle injection molding machine provided in this application adopts the following technical solution:

[0005] A demolding mechanism for an oxygen humidification bottle injection molding machine includes a mold support. The mold support includes a base plate, several columns, and a top plate. The columns are vertically arranged between the base plate and the top plate. An upper mold and a lower mold are arranged between the base plate and the top plate. Cavities are formed on the sides of the upper mold and the lower mold that are close to each other. Lifting cylinders for moving the lower mold or the upper mold are provided on both the base plate and the top plate. A sliding groove is formed at the corner of the cavity of the lower mold, and the sliding groove extends through the lower mold. An ejector rod is vertically arranged on the surface of the base plate and is inserted into the sliding groove. A fixing corner block is provided at the top of the ejector rod. A filling corner block is provided on the bottom wall of the upper mold corresponding to the sliding groove. When the upper mold and the lower mold are closed, the fixing corner block and the filling corner block abut against each other.

[0006] By adopting the above technical solution, when demolding is required during injection molding, the lifting cylinder drives the upper mold and the lower mold to separate. At this time, the filling corner block gradually detaches from the cavity of the lower mold. Due to the presence of the ejector rod, the fixed corner block will remain stationary. The corners of the injection molded product are located on the fixed corner block, thereby separating the injection molded product from the lower mold. During the separation process, since the corners of the injection molded product are located on the fixed corner block, the structure here is formed earlier than other parts of the product and has higher strength. Therefore, it can effectively protect the product structure during demolding and improve demolding quality and convenience.

[0007] Optionally, the fixed corner block includes a base plate and a vertical piece vertically disposed on the surface of the base plate, and the cross-section of the filling corner block is consistent with the cross-section of the fixed corner block.

[0008] By adopting the above technical solution, the fixed corner block and the filling corner block can cover the corners of the oxygen humidification bottle in the injection molding process, thereby effectively improving the injection molding quality.

[0009] Optionally, the top of the vertical piece is provided with a connector, and the bottom wall of the filling corner block is provided with a connector groove for the connector to be inserted.

[0010] By adopting the above technical solution, the insertion piece and insertion groove can effectively improve the sealing between the fixed corner block and the filling corner block, thereby effectively improving the injection molding quality.

[0011] Optionally, the bottom plate sidewall is provided with a sealing sheet, and the bottom wall of the cavity of the lower mold is provided with a sealing groove for the sealing sheet to abut.

[0012] By adopting the above technical solution, the sealing sheet can improve the sealing performance between the fixed corner block and the sliding groove, reduce the probability of leakage of the injection molding material from the gap between the fixed corner block and the sliding groove, and improve the safety and molding quality during the injection molding process.

[0013] Optionally, the bottom wall of the fixed corner block is provided with a plug-in prism, and the top wall of the ejector rod is provided with a prism-shaped hole for the plug-in prism to be inserted.

[0014] By adopting the above technical solution, the fixed corner block and the ejector rod can be detachably connected, which makes it easy to remove the fixed corner block to clean the injection plastic in the corner gaps and improve the subsequent molding quality.

[0015] Optionally, the bottom wall of the prismatic hole is provided with an elastic element, the elastic element is provided with a magnetic element, the magnetic element is magnetically attracted to the inserted prism, the side wall of the magnetic element is provided with a lever, and the inner wall of the prismatic hole is provided with a lever groove for the lever to extend out.

[0016] By adopting the above technical solution, the magnetic attraction between the magnetic component and the plug-in prism can improve the installation stability of the plug-in prism. The setting of the toggle block can facilitate the separation of the magnetic component from the plug-in prism, thereby facilitating the removal of the fixed corner block from the ejector rod and improving the assembly convenience between the fixed corner block and the ejector rod. The setting of the elastic component can facilitate the reset of the magnetic component.

[0017] Optionally, the column is configured to pass through both the upper and lower molds.

[0018] By adopting the above technical solution, the column can limit the movement of the upper and lower molds, thereby effectively ensuring the stability of the upper and lower molds when they are closed and opened.

[0019] Optionally, a buffer spring is fitted on the column, and the buffer spring abuts against the bottom plate and the bottom wall of the lower mold.

[0020] By adopting the above technical solution, the buffer spring can decelerate and buffer the lower mold when the lifting cylinder is damaged and the lower mold falls, thereby effectively protecting the structural safety of the lower mold and extending its service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When demolding is required during injection molding, the lifting cylinder drives the upper mold and the lower mold to separate. At this time, the filling corner block gradually detaches from the cavity of the lower mold. Due to the presence of the ejector rod, the fixed corner block will remain stationary. The edges and corners of the injection molded product are located on the fixed corner block, which in turn allows the injection molded product to separate from the lower mold. During the separation process, because the edges and corners of the injection molded product are located on the fixed corner block, the structure here is formed earlier than other parts of the product and has higher strength. Therefore, it can effectively protect the product structure during demolding, improve demolding quality and convenience.

[0023] 2. Fixed corner blocks and filler corner blocks can cover the edges and corners of oxygen humidification bottles during injection molding, thereby effectively improving the injection molding quality. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a demolding mechanism for an oxygen humidification bottle injection molding machine. (Refer to...) Figure 1 The system includes a mold support 1, which includes a base plate 2, several columns 3, and a top plate 4. The columns 3 are all vertically arranged on the surface of the base plate 2. In this embodiment, the number of columns 3 is set to 4. The top plate 4 is connected to the top of the columns 3. An upper mold 5 and a lower mold 6 are arranged between the base plate 2 and the top plate 4. The columns 3 are arranged through the upper mold 5 and the lower mold 6. A lifting cylinder 8 is provided on both the base plate 2 and the top plate 4 to drive the upper mold 5 and the lower mold 6 to close or open the mold.

[0032] Reference Figure 1 Both the upper mold 5 and the lower mold 6 have cavities 7 on their adjacent sides for injection molding. The lower mold 6 has sliding grooves 9 at the corners of its cavity 7, which extend through the lower mold 6. The bottom plate 2 has several ejector rods 10 on its surface corresponding to the sliding grooves 9. The ejector rods 10 are inserted into the sliding grooves 9, and the top of the ejector rods 10 has a fixed corner block 11 for filling the sliding grooves 9. The bottom wall of the upper mold 5 has a filling corner block 12 formed on its bottom wall corresponding to the position of the sliding grooves 9. When the upper mold 5 and the lower mold 6 are closed, the filling corner block 12 is inserted into the cavity 7 of the lower mold 6 and abuts against the fixed corner block 11.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The fixed corner block 11 includes a base plate 13 and a vertical plate 14 vertically disposed on the surface of the base plate 13. The shape of the vertical plate 14 is based on the shape of the edge of the target product. The cross-section of the filling corner block 12 is consistent with the cross-section of the fixed corner block 11. In this embodiment, the shape of the vertical plate 14 is rounded. The top of the vertical plate 14 is formed with a plug-in piece 15. The bottom wall of the filling corner block 12 is provided with a plug-in groove 16 for the plug-in piece 15 to abut, so as to improve the sealing between the filling corner block 12 and the fixed corner block 11. The periphery of the base plate 13 is formed with a sealing piece 17. The bottom wall of the cavity 7 of the lower mold 6 is provided with a sealing groove 18 for the sealing piece 17 to abut, thereby preventing the leakage of the injection plastic.

[0034] Reference Figure 2 , Figure 4 and Figure 5The bottom wall of the base plate 13 is formed with an insert prism 19, and the top wall of the ejector rod 10 is provided with a prismatic hole 20 for inserting the insert prism 19 to facilitate the disassembly of the fixed corner block 11. The bottom wall of the prismatic hole 20 is provided with an elastic element 21. In this embodiment, the elastic element 21 is a spring. The top of the elastic element 21 is provided with a magnetic element 22. The magnetic element 22 is a magnet. The magnetic element 22 is magnetically attracted to the insert prism 19 to improve the stability of the fixed corner block 11 when it is fixed. The side wall of the magnetic element 22 is provided with a lever 23. The inner wall of the prismatic hole 20 is provided with a lever groove 24 for the lever 23 to extend. By pressing the lever 23, the magnetic element 22 can be separated from the insert prism 19.

[0035] Reference Figure 1 A buffer spring 25 is fitted on the column 3. The buffer spring 25 abuts between the lower mold 6 and the base plate 2 to provide buffering when the lifting cylinder 8 fails.

[0036] The implementation principle of the demolding mechanism for an oxygen humidification bottle injection molding machine according to an embodiment of this application is as follows: When demolding is required during injection molding, the lifting cylinder 8 drives the upper mold 5 and the lower mold 6 to separate. At this time, the filling corner block 12 gradually detaches from the cavity 7 of the lower mold 6. Due to the presence of the ejector rod 10, the fixed corner block 11 will remain stationary. The corner of the injection molded product is located on the fixed corner block 11, thereby separating the injection molded product from the lower mold 6. During the separation process, since the corner of the injection molded product is located on the fixed corner block 11, the structure here is formed earlier and has higher strength than other parts of the product. Therefore, it can effectively protect the product structure during demolding, improve demolding quality and convenience.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
