Description

Technical Field

[0001] This application relates to the field of blister box production, and more particularly to a blister box mold. Background Technology

[0002] Blister box production typically uses blister molds. Heated plastic sheets are pressed together by an upper and lower mold, causing the sheets to adhere to the lower mold's forming cavity. Vacuum suction then holds the sheets within the cavity, forming the desired blister box shape. However, currently, after processing the blister box, demolding is usually done manually by workers. Because the bottom shape of blister boxes is often complex, they easily stick or get stuck in the forming cavity. Workers need to manually and gradually detach the blister from the cavity, making demolding difficult and reducing work efficiency. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a blister box mold that can solve the technical problem that blister boxes are prone to sticking or getting stuck in the forming cavity.

[0004] According to an embodiment of this application, a blister box mold includes: a lower mold, a mounting base, and an ejector section.

[0005] A mounting base is located at the top of the lower mold. The mounting base contains a main forming base, and the top of the main forming base has a main forming cavity. An ejector section is located inside the mounting base, adjacent to the main forming base. The ejector section includes a forming movable base, a transmission column, a connecting arm, and a return spring. The top of the main forming base has a movable cavity that communicates with the main forming cavity. The forming movable base slides into the movable cavity. A snap-fit ​​forming cavity is located on one side of the forming movable base, so that when the forming movable base abuts against the interior of the movable cavity, the snap-fit ​​forming cavity communicates with the main forming cavity. A movable hole is located at the top of the mounting base. The return spring is located inside the movable cavity. The transmission column is mounted on one end of the return spring and slides into the movable hole. The top of the transmission column is slightly higher than the top of the forming movable base. The movable cavity communicates with the movable hole. The connecting arm is located on one side of the transmission column, and one end of the connecting arm is connected to the forming movable base.

[0006] The blister box mold according to the embodiments of this application has at least the following beneficial effects: When the upper mold and the lower mold are closed, since the top of the transmission column is slightly higher than the top of the forming movable seat, the upper mold contacts the transmission column first. When the transmission column is forced to move downward into the interior of the movable hole, the transmission column drives the forming movable seat to slide downward, so that the snap-fit ​​forming cavity is connected to the main body forming cavity. At this time, the heated film is pressed into the snap-fit ​​forming cavity and the main body forming cavity and is squeezed and formed. The snap-fit ​​forming cavity is used to form the snap-fit ​​part of the blister box. When the blister box is formed, the upper mold is separated from the lower mold, the transmission column is separated from the contact of the upper mold, so that the return spring begins to extend. The return spring transmission column moves upward, and the transmission column drives the forming movable seat to slide upward, thereby driving the snap-fit ​​of the blister box to move upward, so that the blister box is separated from the main body forming cavity, thereby realizing the automatic demolding operation of the blister box and avoiding the cumbersome steps of manual demolding required in traditional blister molds.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] Reference Figures 1 to 6 In some embodiments, the blister box mold includes:

[0033] Lower mold 100;

[0034] Mounting base 120 is located on the top of lower mold 100. The interior of mounting base 120 is provided with main body forming base 110, and the top of main body forming base 110 is provided with main body forming cavity 111.

[0035] The ejector section 200 is located inside the mounting base 120. The ejector section 200 is adjacent to the main molding base 110. The ejector section 200 includes a molding movable base 211, a transmission column 220, a connecting arm 221, and a return spring 230. A movable cavity 210 is formed at the top of the main molding base 110, communicating with the main molding cavity 111. The molding movable base 211 slides within the movable cavity 210. A snap-fit ​​molding cavity 212 is formed on one side of the molding movable base 211, allowing the molding movable base 211 to engage with the movable cavity 210. When there is internal contact, the snap-fit ​​forming cavity 212 is connected to the main forming cavity 111. The top of the mounting base 120 is provided with a movable hole 214. The return spring 230 is located inside the movable cavity 210. The transmission column 220 is installed at one end of the return spring 230. The transmission column 220 is slidably engaged with the movable hole 214. The top of the transmission column 220 is slightly higher than the top of the forming movable base 211. The movable cavity 210 is connected to the movable hole 214. The connecting arm 221 is located on one side of the transmission column 220. One end of the connecting arm 221 is connected to the forming movable base 211.

[0036] Understandably, when the upper and lower molds 100 close, since the top of the transmission column 220 is slightly higher than the top of the molding movable seat 211, the upper mold contacts the transmission column 220 first. When the transmission column 220 is forced downward and moves into the interior of the movable hole 214, the transmission column 220 drives the molding movable seat 211 to slide downward, making the snap-fit ​​molding cavity 212 connected to the main body molding cavity 111. At this time, the heated film is pressed between the snap-fit ​​molding cavity 212 and the main body molding cavity 111 and is extruded and molded, wherein the snap-fit ​​molding... Cavity 212 is used to form the snap-fit ​​part of the blister box. After the blister box is formed, the upper mold separates from the lower mold 100, and the transmission column 220 disengages from the upper mold, causing the return spring 230 to extend. The return spring 230 and transmission column 220 move upward, and the transmission column 220 drives the forming movable seat 211 to slide upward, thereby driving the snap-fit ​​part of the blister box to move upward, so that the blister box separates from the main forming cavity 111, thus realizing the automatic demolding operation of the blister box, avoiding the cumbersome steps of manual demolding required in traditional blister molds.

[0037] Furthermore, the material of the molding seat 211 can be selected as a high-temperature resistant, low-friction engineering material to improve service life and processing accuracy; the sliding fit between the transmission column 220 and the movable hole 214 can be optimized into a rolling structure, such as by adding ball bearings or sliders, to further reduce transmission friction; at the same time, the elastic parameters of the return spring 230 can be adjusted according to the size and material characteristics of the blister box to meet different production needs; and the number of the main molding seat 110 and the ejector part 200 can be adjusted to multiple according to production needs.

[0038] Reference Figures 5 to 6In some embodiments, a first connecting groove 213 is provided on one side of the movable cavity 210, and a second connecting groove 215 is provided on one side of the movable hole 214. The second connecting groove 215 communicates with the first connecting groove 213, and one end of the connecting arm 221 passes through the first connecting groove 213 and the second connecting groove 215, so that one end of the connecting arm 221 is connected to the molded movable seat 211.

[0039] It is understandable that when the drive column 220 moves up and down, it will drive the connecting arm 221 to move up and down. The design of the first connecting groove 213 and the second connecting groove 215 provides the movement path of the connecting arm 221, so that it can smoothly pass through the movable cavity 210 and connect to the movable hole 214, ensuring the molding accuracy and smooth demolding of the blister box.

[0040] Furthermore, the shapes of the first connecting groove 213 and the second connecting groove 215 can be optimized into trapezoidal grooves or arc-shaped grooves to adapt to different types of connecting arm 221 and forming movable seat 211 structures; the processing methods of the first connecting groove 213 and the second connecting groove 215 can also adopt precision milling or laser cutting to improve the smoothness of the groove opening and reduce the influence of friction on the movement of the connecting arm 221; in addition, the shape and size of the connecting arm 221 can be adjusted to cylindrical or flat shape according to actual needs to enhance the flexibility of sliding fit.

[0041] Reference Figures 5 to 6 In some embodiments, the ejector part 200 includes a fixing bolt 226 and a connecting block 222. The top of the main molding seat 110 is provided with a connecting slot 250, which connects the first connecting groove 213 and the movable cavity 210. The connecting block 222 is located on one side of the molding movable seat 211 and is located inside the connecting slot 250. One end of the connecting arm 221 extends into the interior of the connecting slot 250, so that the connecting block 222 is located above the connecting arm 221. The interior of the connecting block 222 is provided with a first fixing hole 225, and one end of the connecting arm 221 is provided with a second fixing hole 227. The fixing bolt 226 passes through the first fixing hole 225, so that one end of the fixing bolt 226 is threadedly engaged with the second fixing hole 227.

[0042] Understandably, in actual production, the snap-fit ​​requirements of blister boxes will vary from batch to batch. Therefore, when each batch changes, the connecting block 222 can be loosened by rotating the fixing bolt 226 and the molding movable seat 211 can be replaced. After replacement, the connecting block 222 can be tightened again by the fixing bolt 226. This design not only allows the connecting arm 221 to maintain a stable sliding fit with the connecting block 222, but also allows the molding movable seat 211 to be quickly replaced when needed to adapt to the snap-fit ​​requirements of blister boxes of different specifications.

[0043] In addition, the connecting slot 250 provides installation space for the connecting block 222 while ensuring its movement accuracy during the demolding process; the fixing bolt 226 can be replaced with spring clips or quick-release fasteners to further simplify the replacement process of the molding movable seat 211; the shape of the connecting block 222 can be optimized into a trapezoidal or ring structure according to the overall mold design to increase its connection area with the molding movable seat 211; the depth and width of the connecting slot 250 can also be adjusted according to different specifications of the molding movable seat 211 to enhance compatibility and ease of operation.

[0044] Reference Figures 5 to 6 In some embodiments, the ejector part 200 includes a positioning pin 223, and one end of the connecting arm 221 is provided with a positioning hole 224. The positioning pin 223 is located at the bottom of the connecting block 222 and is inserted into the positioning hole 224.

[0045] Understandably, the positioning pin 223 is inserted into the positioning hole 224 of the connecting arm 221, which makes the alignment of the connecting block 222 and the connecting arm 221 more accurate and greatly improves the connection stability between the connecting block 222 and the connecting arm 221, avoiding the problem of the molding movable seat 211 shifting or loosening during the sliding process.

[0046] Furthermore, the depth and diameter of the positioning socket 224 can be adjusted according to the mold size to enhance the tightness of the insertion. Additionally, the positioning pin 223 can be made of a highly wear-resistant cemented carbide or corrosion-resistant stainless steel to extend the service life of the mold.

[0047] Reference Figure 5 In some embodiments, the ejector part 200 includes a limiting insert 251, a fixed side plate 252, and connecting bolts 255. The limiting insert 251 is inserted into the connecting slot 250, so that the limiting insert 251 is located above the connecting block 222. There are two fixed side plates 252, which are located on both sides of the limiting insert 251. The fixed side plates 252 abut against the main body molding seat 110. The top of the main body molding seat 110 has two first connecting holes 253. The interior of the fixed side plate 252 has a second connecting hole 254. There are two connecting bolts 255, which pass through the second connecting holes 254 of the two fixed side plates 252 respectively, so that the two connecting bolts 255 are threadedly engaged with the two first connecting holes 253 respectively.

[0048] It is understandable that by inserting the limiting plug 251 into the connecting slot 250, the fixed side plate 252 abuts against the main body molding seat 110, and at the same time, the limiting plug 251 is fastened to the molding seat by the connecting bolt 255, which plays a role in restricting the movement space above the connecting block 222 and preventing the connecting block 222 from detaching or shifting due to excessive force.

[0049] In addition, the shape of the limiting plug 251 can be designed as L-shaped or arc-shaped to better adapt to specific mold structure requirements; the material of the fixing side plate 252 can be selected as high-strength alloy or composite material to improve fatigue resistance; the connecting bolt 255 can be replaced with quick-release screw or snap-fit ​​structure to simplify the assembly and maintenance process; the plugging method of the connecting slot 250 can also be replaced by a precision slide rail design to further improve installation accuracy and ease of operation.

[0050] Reference Figure 6 In some embodiments, the ejector part 200 includes a first mounting post 231 and a second mounting post 233. The first mounting post 231 is located inside the movable hole 214, and the other end of the return spring 230 is inserted into the first mounting post 231. The second mounting post 233 is located at the bottom of the transmission post 220, and the second mounting post 233 is inserted into one end of the return spring 230.

[0051] Understandably, the insertion design of the first mounting post 231 and the second mounting post 233 forms a stable reset support structure. The fixation of the reset spring 230 ensures that there will be no positional shift or loosening during multiple working cycles. At the same time, the reset operation is smooth, avoiding jamming problems caused by improper mold reset.

[0052] Furthermore, the first mounting post 231 and the second mounting post 233 can be replaced with a threaded connection structure to allow adjustment of the length and preload of the return spring 230 when needed. The first mounting post 231 and the second mounting post 233 can be made of high-strength steel or wear-resistant composite materials to enhance their durability. The insertion method of the return spring 230 can also be replaced with a magnetic adsorption or locking design, further simplifying installation and maintenance.

[0053] Reference Figure 6 In some embodiments, the ejector portion 200 includes two first locking protrusions 232 and two second locking protrusions 234. The two first locking protrusions 232 are located on both sides of the first mounting post 231, and the first locking protrusions 232 on both sides of the first mounting post 231 are internally engaged with the other end of the return spring 230. The two second locking protrusions 234 are located on both sides of the second mounting post 233, and the second locking protrusions 234 on both sides of the second mounting post 233 are internally engaged with one end of the return spring 230.

[0054] Understandably, the first locking protrusion 232 and the second locking protrusion 234 fix the return spring 230 at both ends of the first mounting post 231 and the second mounting post 233 by locking, forming a solid return structure. When the transmission post 220 drives the return spring 230 to compress, the locking protrusion ensures that the return spring 230 will not be dislodged from the mounting post due to external force. After the external force is released, the return spring 230 transmits the extension force through the first locking protrusion 232 and the second locking protrusion 234, driving the molding movable seat 211 to return to its original position, while maintaining the stability and elastic recovery capability of the overall structure.

[0055] In addition, the first locking protrusion 232 and the second locking protrusion 234 can be replaced with elastic clamping rings or threaded snaps to accommodate return springs 230 of different diameters and specifications; the materials of the first locking protrusion 232 and the second locking protrusion 234 can be wear-resistant and have good toughness, such as polymer composite materials or elastic alloys, to improve their adaptability and durability; at the same time, the snap-fit ​​method can be optimized into a detachable design to facilitate quick replacement and maintenance of the return spring 230.

[0056] Reference Figure 6 In some embodiments, the ejector part 200 includes a mounting screw 241 and a protective top plate 242. The mounting screw 241 is located at the bottom of the protective top plate 242, and the top of the transmission column 220 is provided with a mounting groove 240. The mounting screw 241 is threadedly engaged with the mounting groove 240.

[0057] Understandably, when the upper mold contacts the transmission column 220, the protective top plate 242 will absorb the impact force of the upper mold instead of the transmission column, preventing the transmission column 220 from deforming or being damaged due to direct force; at the same time, the protective top plate 242 can also provide additional support for the transmission column 220, enhancing the overall durability of the mold.

[0058] In addition, the mounting screw 241 can be replaced with a quick-release buckle or magnetic fixing structure to enable quick disassembly and replacement of the protective top plate 242; the material of the protective top plate 242 can be selected from high-temperature resistant and impact-resistant engineering plastics or composite materials to further enhance its performance; the depth and diameter of the mounting groove 240 can also be adjusted according to the design requirements of different molds to improve the installation flexibility and compatibility of the protective top plate 242.

[0059] Reference Figure 6 In some embodiments, the ejector portion 200 includes a buffer pad 243, which is disposed on the top of the protective top plate 242 and is elastic.

[0060] Understandably, the buffer pad 243 is installed on top of the protective top plate 242. When the upper mold contacts the transmission column 220, the buffer pad 243 absorbs the impact force and evenly distributes the pressure, thereby protecting the transmission column 220 and the entire mold structure from direct impact and damage. The elastic properties of the buffer pad 243 enable it to quickly return to its original shape after compression, ensuring the stable operation of the mold.

[0061] In addition, the buffer pad 243 can be made of materials with different hardness and elasticity, such as silicone rubber, polyurethane or elastic foam, to adapt to different working conditions; the shape of the buffer pad 243 can be designed as corrugated or multi-layered structure to enhance the buffering effect; in addition, the buffer pad 243 can be connected to the protective top plate 242 by various methods such as bonding, embedding or threading to improve the ease of installation and structural stability.

[0062] Reference Figure 6 In some embodiments, the mounting base 120 has a positioning groove 121 inside, the positioning groove 121 matches the shape of the main body forming base 110, and the main body forming base 110 is located inside the positioning groove 121.

[0063] Understandably, the positioning groove 121 ensures that the main body forming seat 110 is firmly fixed during installation by precisely matching the shape of the main body forming seat 110, thus preventing the main body forming seat 110 from shifting due to vibration or external force during mold operation. After the main body forming seat 110 is placed in the positioning groove 121, its fit with the positioning groove 121 ensures the alignment of the forming cavity and the movable cavity 210, thereby ensuring the accuracy and stability of the blister box forming process.

[0064] Furthermore, the design of the positioning groove 121 can be optimized into an adjustable structure, such as by adding wedge-shaped clamps or elastic clamps, to adapt to the main body forming seat 110 of different sizes; the positioning groove 121 can be processed by high-precision CNC milling or electrical discharge machining to improve its surface accuracy and fitting performance; in addition, the material of the positioning groove 121 can be selected from high-strength steel or wear-resistant composite materials according to the working environment of the mold to enhance its durability.

[0065] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
