Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold manufacturing technology, and in particular to lipstick tube molds. Background Technology
[0002] As a key tool used in manufacturing lipstick tubes, lipstick tube molds involve cutting-edge knowledge and technology applications in multiple fields such as mechanical design, materials science, CNC machining, and surface treatment. A high-quality lipstick tube mold not only needs to have high-precision cavity design and manufacturing process to ensure that the produced lipstick tubes are accurate in size, smooth in appearance, and free of defects, but also needs to fully consider factors such as mold lifespan, production efficiency, and maintenance costs.
[0003] In the practical application of lipstick tube molds, existing lipstick tube molds have many problems. On the one hand, the mold closing accuracy is difficult to guarantee. This is because the lack of an effective external docking and fixing structure makes it easy for the upper and lower mold bases to slightly shift during mold closing, which leads to deviations in the size of the produced lipstick tubes, affecting subsequent assembly and normal use. On the other hand, the outer side of the upper and lower mold bases lacks protective buffer design. When subjected to external impacts, the internal structure of the mold will inevitably be affected, resulting in a decrease in the stability of subsequent mold closing, further negatively impacting product quality, and also increasing mold wear and production costs.
[0004] Therefore, a lipstick tube mold was proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a lipstick tube mold that can solve many problems existing in the current lipstick tube mold. On the one hand, the mold closing accuracy is difficult to guarantee because there is no effective external docking and fixing structure, which makes it easy for the upper and lower mold bases to slightly shift during mold closing, resulting in deviations in the size of the produced lipstick tubes, affecting subsequent assembly and normal use. On the other hand, the outer side of the upper and lower mold bases lacks a protective buffer design. When subjected to external impacts, the internal structure of the mold will inevitably be affected, resulting in a decrease in the stability of subsequent mold closing, further negatively impacting product quality, and also increasing mold wear and production costs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a lipstick tube mold, including an upper mold base, a lower mold base being provided at the bottom of the upper mold base, and a mold closing reinforcement and protection mechanism being provided on the outer sides of the upper mold base and the lower mold base;
[0007] The mold clamping reinforcement and protection mechanism includes a fixing plate bolted to the outer perimeter of the upper mold base, and connecting plates bolted to the outer perimeter of the lower mold base. The top of the connecting plate contacts the bottom of the fixing plate, and a mating groove is provided on the top of the connecting plate. A mating plate is fixedly connected to the bottom of the fixing plate, and the mating plate is inserted into the mating groove. A protective structure is provided on the outer side of the connecting plate.
[0008] Preferably, the protective structure includes an inner protective plate bolted to the outside of the connecting plate, and a rubber buffer column is adhered to the outside of the inner protective plate.
[0009] Preferably, an outer buffer plate is adhered to the outside of the rubber buffer post, and the outer buffer plate is located outside the inner protective plate.
[0010] Preferably, an anti-wear and anti-pressure sheet is bonded to the outer side of the outer buffer plate, and the anti-wear and anti-pressure sheet is made of metal material.
[0011] Preferably, positioning grooves are provided at the four corners of the top of the upper mold base, and positioning rods are bolted to the four sides of the top of the lower mold base, with the positioning rods inserted into the positioning grooves.

[0013] Preferably, a limiting piece is adhered to the outer side of the inner protective plate, and the limiting piece is located on the outer side of the outer buffer plate.
[0014] Preferably, a fastening pad is bonded to the inside of the mating groove, and the fastening pad is located on the outside of the mating plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This application provides an effective external mating and fixing structure for the mold closing by setting up a mold closing reinforcement and protection mechanism. The mating plate at the bottom of the fixed plate and the mating groove at the top of the connecting plate are interlocked. This structure can limit the horizontal displacement of the upper and lower mold bases during the mold closing process, prevent slight misalignment between the upper and lower mold bases, and thus ensure the mold closing accuracy, reduce the dimensional deviation of the produced lipstick tubes, and ensure the smooth progress of subsequent assembly processes and the normal use of the lipstick tubes.
[0017] 2. This application sets up a protective structure to form a protective buffer on the outside of the upper and lower mold bases. When the upper and lower mold bases are subjected to external impact, the protective structure can absorb and disperse the impact force, reduce the impact force on the internal structure of the upper and lower mold bases, ensure the stability of subsequent mold closing, improve product quality, and at the same time reduce mold wear and reduce production costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] The lipstick tube mold includes an upper mold base 1, a lower mold base 2 is provided at the bottom of the upper mold base 1, and a mold closing reinforcement and protection mechanism 3 is provided on the outer side of the upper mold base 1 and the lower mold base 2.
[0027] The mold clamping reinforcement and protection mechanism 3 includes a fixing plate 31 bolted to the outer periphery of the upper mold base 1, and a connecting plate 32 bolted to the outer periphery of the lower mold base 2. The top of the connecting plate 32 contacts the bottom of the fixing plate 31. A mating groove 33 is provided on the top of the connecting plate 32. A mating plate 34 is fixedly connected to the bottom of the fixing plate 31. The mating plate 34 is inserted into the inside of the mating groove 33. A protective structure 35 is provided on the outer side of the connecting plate 32.
[0028] In this embodiment: By setting a mold closing reinforcement and protection mechanism 3, when the lipstick tube mold is closed, the upper mold base 1 moves closer to the lower mold base 2. Since the fixing plate 31 is bolted to the outer periphery of the upper mold base 1 and the connecting plate 32 is bolted to the outer periphery of the lower mold base 2, and the mating plate 34 at the bottom of the fixing plate 31 and the mating groove 33 at the top of the connecting plate 32 cooperate with each other, the mating plate 34 will accurately insert into the mating groove 33 during the mold closing process. This cooperation provides precise positioning and a stable connection for the upper mold base 1 and the lower mold base 2, effectively limiting the horizontal displacement of the upper mold base 1 and the lower mold base 2, so that the two can close the mold accurately and avoid production problems caused by slight displacement during mold closing. The dimensional deviation of the produced lipstick tube ensures the dimensional accuracy of the lipstick tube, which is conducive to the smooth progress of subsequent assembly work. At the same time, the protective structure 35 set on the outside of the connecting plate 32 will first absorb and disperse the impact force if the outer side of the upper mold base 1 and the lower mold base 2 is impacted during daily handling, installation or use. This greatly reduces the impact force on the internal structure of the upper mold base 1 and the lower mold base 2, so that good stability can still be maintained in the subsequent mold closing process. This ensures the quality of the produced lipstick tube, reduces mold wear, extends the mold service life, and effectively reduces production costs.
[0029] Specifically, such as Figure 4 As shown, the protective structure 35 includes an inner protective plate 351 bolted to the outside of the connecting plate 32, and a rubber buffer post 352 is bonded to the outside of the inner protective plate 351.
[0030] Specifically, such as Figure 4 As shown, an outer buffer plate 353 is bonded to the outside of the rubber buffer post 352, and the outer buffer plate 353 is located outside the inner protective plate 351.
[0031] Specifically, such as Figure 4 As shown, an anti-wear and anti-pressure sheet 354 is bonded to the outer side of the outer buffer plate 353. The anti-wear and anti-pressure sheet 354 is made of metal material.
[0032] In this embodiment: by setting up a protective structure 35, when the upper mold base 1 and the lower mold base 2 are subjected to external impact, the outer buffer plate 353 is the first to bear the impact. The wear-resistant and pressure-resistant sheet 354 on its outer side is made of metal material, which can resist part of the impact force with its high strength, reducing the direct damage of external objects to the upper mold base 1 and the lower mold base 2. Then, the impact force is transmitted to the rubber buffer column 352. The properties of rubber material make it have good elasticity, which can effectively absorb and disperse the impact force, further weakening its strength. The inner protective plate 351 is inside the rubber buffer column 352, providing more direct protection for the connecting plate 32 and preventing the impact force from damaging the connecting plate 32. This series of structures work together to comprehensively reduce the impact force on the internal structure of the upper mold base 1 and the lower mold base 2, ensuring that the upper mold base 1 and the lower mold base 2 remain stable in the subsequent mold closing process, ensuring the production quality of lipstick tubes, and extending the service life of the upper mold base 1 and the lower mold base 2.
[0033] Specifically, such as Figure 2 As shown, positioning grooves 4 are provided at the four corners of the top of the upper mold base 1, and positioning rods 5 are bolted to the four sides of the top of the lower mold base 2. The positioning rods 5 are inserted into the inside of the positioning grooves 4.
[0034] Specifically, such as Figure 3 As shown, an arc plate 6 is fixedly connected to the bottom of the mating plate 34, and the arc plate 6 is located inside the mating groove 33.
[0035] In this embodiment: by setting the positioning groove 4, the positioning rod 5 and the arc plate 6, during the mold closing process, the positioning rod 5 at the top of the lower mold base 2 can be accurately inserted into the positioning groove 4 at the top of the upper mold base 1. This provides preliminary positioning for the upper mold base 1 and the lower mold base 2 in the vertical direction, making the relative position of the upper mold base 1 and the lower mold base 2 more accurate, and further improving the accuracy of mold closing. The arc plate 6 at the bottom of the docking plate 34 is located inside the docking groove 33. The smooth curved surface of the arc plate 6 can guide the docking plate 34 when it is inserted into the docking groove 33, making the insertion process smoother and reducing jamming and deviation.
[0036] Specifically, such as Figure 4 As shown, a limiting piece 7 is bonded to the outer side of the inner protective plate 351, and the limiting piece 7 is located on the outer side of the outer buffer plate 353.
[0037] Specifically, such as Figure 5 As shown, a fastening pad 8 is bonded to the inside of the mating groove 33, and the fastening pad 8 is located on the outside of the mating plate 34.
[0038] In this embodiment: By setting a limiting piece 7 and a fastening pad 8, the limiting piece 7 is located outside the outer buffer plate 353. It can limit the excessive displacement of the outer buffer plate 353 when it is impacted, ensuring the overall stability and maintaining a good working state during the absorption and dispersion of impact force. The fastening pad 8 is bonded inside the docking groove 33 and located outside the docking plate 34. It increases the friction between the docking plate 34 and the docking groove 33, making the connection of the docking plate 34 in the docking groove 33 tighter and more stable, further enhancing the positioning and fixing effect during mold closing, ensuring mold closing accuracy, and improving the production quality of lipstick tubes.
[0039] Working principle: During the use of the lipstick tube mold, in the initial mold closing stage, the upper mold base 1 and the lower mold base 2 begin to close. The positioning rod 5 on the top of the lower mold base 2 is precisely inserted into the positioning grooves 4 at the four corners of the top of the upper mold base 1. This step provides initial positioning for the upper mold base 1 and the lower mold base 2 in the vertical direction, making their relative positions more accurate and laying the foundation for precise mold closing. At the same time, the fixing plate 31 is bolted to the outside of the upper mold base 1, and the connecting plate 32 is bolted to the outside of the lower mold base 2. As the mold closing action progresses, the mating plate 34 at the bottom of the fixing plate 31 is in the mating groove 3. 3. Insertion: During this process, the arc plate 6 at the bottom of the mating plate 34, with its smooth curved surface, acts as a guide, making the insertion of the mating plate 34 smoother and reducing jamming and deviation. After insertion, the mating plate 34 and the mating groove 33 fit tightly together, providing precise positioning and a stable connection for the upper mold base 1 and the lower mold base 2 in the horizontal direction. This greatly limits horizontal displacement, ensures mold closing accuracy, and avoids lipstick tube size deviation due to mold closing offset, ensuring smooth subsequent assembly. However, during the daily handling, installation, or use of the mold, it is inevitably subject to external impacts and collisions. The protective structure 35 on the outside of the connecting plate 32 plays a crucial role. When impacted, the metal anti-wear and anti-pressure plate 354 on the outside of the outer buffer plate 353 resists part of the impact force with its high strength, reducing the direct damage of external objects to the upper mold base 1 and the lower mold base 2. Then, the impact force is transmitted to the rubber buffer pillar 352, which absorbs and disperses the impact force using the good elasticity of rubber, further weakening its strength. The inner protective plate 351 located on the inside directly protects the connecting plate 32, preventing the impact force from damaging it. In addition, the limiting piece 7 on the outside of the inner protective plate 351 restricts the external impact force. The excessive displacement of the buffer plate 353 ensures the stability of the protective structure 35 and continuously and effectively protects the upper mold base 1 and the lower mold base 2. In terms of the stability of mold closing positioning, the fastening pad 8 in the mating groove 33 increases the friction between the mating plate 34 and the mating groove 33, making the connection between the two tighter and more stable, further enhancing the positioning and fixing effect during mold closing, ensuring mold closing accuracy, improving the production quality of lipstick tubes, and within the service life, the overall structure works together to extend the service life of the upper mold base 1 and the lower mold base 2, reduce production costs, and achieve high-quality and high-efficiency production of lipstick tubes.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
