Detailed Implementation
[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] like Figures 1 to 12As shown, the mold assembly of this utility model includes an outer forming mold 1 and an inner forming mold 2. The outer forming mold 1 has an outer forming cavity in the middle. The inner forming mold 2 includes a support connector 21. A removable inner mold body 22 is provided on the support connector 21. The inner forming mold 2 is vertically and detachably set in the outer forming cavity through the support connector 21. The main cavity is between the inner wall of the outer forming cavity and the outer wall of the inner mold body 22.
[0034] The outer surface of the inner mold body 22 is provided with a first pattern forming structure.
[0035] The method for preparing a glass container using the mold assembly of this utility model includes the following steps:
[0036] The method for preparing glass containers includes the following steps:
[0037] a. Fabricate and prepare mold components, such as Figure 9 As shown;
[0038] b. The glass material is fired into a molten glass liquid, which is then poured into the main body cavity. After the molten glass liquid cools and solidifies, it forms the glass container body 31, and the internal molding mold 2 is embedded in the glass container body 31. Figure 10 As shown;
[0039] c. Remove the glass container body 31 and the inner forming mold 2 from the outer forming mold 1, as follows: Figure 11 As shown;
[0040] d. Anneal the glass container body 31;
[0041] e. Remove the internal forming mold 2 from the glass container body 31, and form the internal shape of the glass container 3 within the glass container body 31, thereby obtaining the glass container 3, as shown. Figure 12 As shown.
[0042] During the manufacturing of this glass container, the outer forming cavity in the outer forming mold 1 is formed into the outer shape of the glass container 3, and the main body cavity is formed into the glass container body 31. The inner forming mold 2 is formed into the inner shape of the glass container 3 within the glass container body 31. By designing outer forming cavities and inner forming molds 2 of different shapes, and by setting pattern forming structures on the outer surface of the inner forming mold 2, a glass container 3 with an outer shape that is inconsistent with the inner shape and an embossed pattern on the inner surface can be manufactured.
[0043] To ensure the production of a glass container 3 with an external shape that does not match its internal shape and an embossed pattern on the internal surface, a preferred structure for the mold assembly of this invention is as follows: (Example...) Figures 1 to 10As shown, the outer shape forming mold 1 includes a left outer shape clamp 11, a right outer shape clamp 12, a base 13, a rotating shaft 14, and a connecting locking fastener 15. The rotating shaft 14 is vertically arranged on the base 13. The left outer shape clamp 11 and the right outer shape clamp 12 are arranged above the base 13. The rear side of the left outer shape clamp 11 is fitted onto the left side of the rotating shaft 14, and the left outer shape clamp 11 can rotate left and right around the rotating shaft 14. The rear side of the right outer shape clamp 12 is fitted onto the left side of the rotating shaft 14, and the right outer shape clamp 12 can rotate left and right around the rotating shaft 14. The front side of the left outer shape clamp 11 and the front side of the right outer shape clamp 12 are detachably connected together by the connecting locking fastener 15.
[0044] The left clamp 11 is provided with a left shape forming groove 111, and the right clamp 12 is provided with a right shape forming groove 121. When the left clamp 11 and the right clamp 12 are closed, the left shape forming groove 111 and the right shape forming groove 121 form a shape forming cavity.
[0045] In the inner forming mold 2, the inner mold body 22 serves to form the internal shape of the glass container 3, and the supporting connector 21 serves to connect and support the inner mold body 22 and to connect and position it with the outer forming mold 1. To improve the effectiveness of the supporting connector 21, for example... Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the support connector 21 includes a connecting part and a support part connected together. The support part is located above the connecting part, and the inner mold body 22 is fitted onto the support part. The base 13 has a positioning hole 131 in the middle, and the lower half of the connecting part is detachably fitted into the positioning hole 131. The support part serves to connect and support the inner mold body 22, while the connecting part serves to connect and position with the outer forming mold 1, and also serves to be easily handled by the user.
[0046] The removal of the internal forming mold 2 from the glass container body 31 and the formation of the internal shape of the glass container 3 within the glass container body 31 refers to the internal forming mold 2 being embedded within the glass container body 31. After removing the internal forming mold 2 from the glass container body 31, the internal shape of the glass container 3 is formed in the middle of the glass container body 31. The purpose is to form the internal shape of the glass container 3 in the middle of the glass container body 31. The removal of the internal forming mold 2 from the glass container body 31 can be a complete removal of the internal forming mold 2, or the removal of a portion of it while other components are removed, as long as the internal shape of the glass container 3 can be formed in the middle of the glass container body 31. Through extensive practice and experimentation, this invention preferably forms the internal shape of the glass container 3 by removing the internal forming mold body 22, and then removing the supporting connector 21 from the inside of the glass container 3. To achieve the removal of the internal forming mold body 22 to form the internal shape of the glass container 3, for example... Figure 4 , Figure 5 and Figure 6 As shown, the inner mold body 22 is made of plaster. A liquid flow through hole 211 is provided in the middle of the support connector 21. The liquid flow through hole 211 is arranged along the length direction of the support connector 21. A liquid inlet hole 212 is provided on the connecting part. At least one liquid outlet hole 213 is provided on the support part. The liquid outlet holes 213 are spaced apart along the length direction of the support part. The liquid inlet hole 212 and the liquid outlet hole 213 are respectively connected to the liquid flow through hole 211. Since the connecting part serves to connect and position with the outer forming mold 1, in step b, the connecting part is positioned and connected with the outer forming mold 1. There will be no glass solution at the connecting part, the connecting part will not be embedded in the glass container body 31, and the liquid inlet hole 212 on the connecting part will not be blocked. In step e, the glass container body 31 is immersed in water or hydrochloric acid solution. The water or hydrochloric acid solution enters the liquid flow passage 211 through the liquid inlet hole 212, and then the liquid flow passage 211 contacts the plaster inner mold body 22 through the liquid outlet hole 213 and reacts, so that the inner mold body 22 is eliminated to form the internal shape of the glass container 3, while the supporting connecting part 21 is left inside the glass container 3. Then the supporting connecting part 21 is removed from the inside of the glass container 3.
[0047] The inner mold body 22 is made of plaster and is formed by casting in a plaster mold. The inner mold body 22 could be made entirely of plaster, but this would be costly and heavy, making it inconvenient to use. To reduce the cost and weight of the inner mold body 22, for example... Figure 5As shown, the inner mold body 22 includes an outer mold part 221 and an inner mold part 222. The inner mold part 222 has a hollow structure and is made of foam. The outer mold part 221 is fitted and connected to the outside of the inner mold part 222. During the preparation of the inner mold body 22, the inner mold part 222 is first formed on the support part of the support connector 21 using a foam mold. Then, the outer mold part 221 is formed by casting plaster molds onto the inner mold part 222. Since the inner mold part 222 is made of foam, the high temperature used in step d during annealing will melt the inner mold part 222, without affecting step e.
[0048] To improve the connection strength of the inner mold body 22, the outer surface of the support is provided with external threads. The threaded structure facilitates the attachment of the inner mold body 22 to the support. The entire inner mold body 22 or the outer mold body 221 is made of plaster. In the plaster mold, the molten plaster also solidifies into solid plaster. To prevent the liquid flow passage 211 from being blocked during the preparation of the inner mold body 22, thus affecting the use of the liquid flow passage 211, for example... Figure 7 As shown, this utility model also includes a sealing rod 23, which is detachably and matched in the liquid flow passage 211. During the preparation of the inner mold body 22, the sealing rod 23 seals the liquid flow passage 211 to prevent blockage. After the inner mold body 22 is prepared, the sealing rod 23 is removed from the liquid flow passage 211 so that the sealing rod 23 does not affect the subsequent use of the inner mold 2.
[0049] The inner mold body 22 needs to be formed in a plaster mold during preparation, while the glass container 3 needs to be formed in both the outer mold 1 and the inner mold 2. To improve the forming quality of the inner mold body 22 and the glass container 3, taking the forming of the glass container 3 as an example... Figure 5 As shown, this utility model provides a limiting plate 214 and a positioning plate 215 in the circumferential direction of the connecting part. The positioning plate 215 is located above the limiting plate 214. The outer forming cavity includes a main body cavity segment and a connecting positioning cavity segment connected together. The main body cavity segment is located above the connecting positioning cavity segment. The positioning plate 215 is detachably matched and installed in the connecting positioning cavity segment. The limiting plate 214 and the positioning plate 215 play the role of connection and positioning. This arrangement ensures that the connecting part is completely wrapped by the outer forming cavity, so that it will not be contaminated with glass solution. The connecting part will not be embedded in the glass container body 31. The connecting part will be on the upper side of the glass container body 31. The connecting part can be used as a pick-up position for user convenience.
[0050] To further improve the molding quality of glass container 3, for example... Figure 10As shown, the forming cavity also includes a pressure head mounting section, which is connected and positioned above the main cavity section. It also includes a pressure head 16, which is detachably fitted into the pressure head mounting section. In step b, after pouring molten glass into the main cavity, the pressure head 16 is fitted into the pressure head mounting section to compact the molten glass in the main cavity. After cooling, the pressure head 16 is removed. Furthermore, to facilitate the use of the pressure head 16, it includes a stamping part 161 and a handle post 162. The handle post 162 is connected and positioned above the stamping part 161, and the stamping part 161 is detachably fitted into the pressure head mounting section. A second pattern forming structure can also be provided on the lower surface of the stamping part 161. This second pattern forming structure will create an embossed pattern on the bottom of the formed glass container 3, improving the anti-counterfeiting and aesthetics of the glass container 3 and enriching the product offerings.
[0051] Since molten glass has a high temperature, a high-temperature resistant coating is provided on the outer surface of the inner mold body 22 to improve its high-temperature resistance.
[0052] The inner mold body 22 is made of plaster, for example... Figure 12 As shown, in step e, the glass container body 31 is completely immersed in water or hydrochloric acid solution, thereby eliminating the internal forming mold 2 and forming the internal shape of the glass container in the glass container body 31.
[0053] In summary, the mold assembly of this utility model includes an external forming mold 1 and an internal forming mold 2. During the preparation of the glass container, the external forming cavity in the external forming mold 1 is formed into the external shape of the glass container 3, and is formed into the glass container body 31 in the main body cavity. The internal forming mold 2 is formed into the internal shape of the glass container 3 in the glass container body 31. By designing external forming cavities and internal forming molds of different shapes, and by setting pattern forming structures on the outer surface of the internal forming mold 2, a glass container with an external shape that is inconsistent with the internal shape and an embossed pattern on the internal surface can be prepared.
