Description

Technical Field

[0001] The utility model belongs to the field of mold sealing of plastic shells, and in particular relates to a mold sealing structure of a plastic shell. Background Art

[0002] Plastic shell molds are one of the key technologies to ensure high-quality production of plastic products. By continuously innovating and improving aspects such as sealing structure design, material selection, and processing technology, we can further improve the production efficiency and quality of plastic products. With the ever-changing consumer demand for beverages and their penchant for novelty, PET plastic bottles have become a dominant force in beverage packaging. Therefore, the sealing performance of the mold is of great significance in both the production and manufacturing process.

[0003] The prior art has specially developed some structures for sealing plastic shell molds. For example, the Chinese patent with the announcement number "CN208629748U" announced "A new type of plastic mold sealing structure". The left half base of the mold sealing mechanism and the right half base of the mold sealing mechanism are respectively located at the two ends of the left half base and the left half base of the mold. When in use, the left half base of the mold sealing mechanism and the right half base of the mold sealing mechanism are docked. When docking, the convex groove of the docking surface extends into the groove of the docking surface, which can be perfectly engaged, thereby enhancing the sealing effect. When the sealing performance of the rubber ring decreases after a period of use, it will not cause the product to be defective and scrapped, affecting quality and efficiency.

[0004] Although the left half of the base can be docked with the right half of the base of the mold sealing mechanism, and the convex groove of the docking surface can be extended into the groove of the docking surface to achieve perfect engagement, thereby enhancing the sealing effect, there is no fixed connection structure when the left half of the sealing base is connected to the right half of the base. When taking the mold body, it will cause the left half of the sealing base or the right half of the base to slide off. If the left half of the sealing base or one of the right half of the base slides off, it will cause the sealing base itself to be destroyed. When trying to use the sealing base, gaps of varying degrees will appear, resulting in a decline in the quality of the plastic product. The left half of the sealing base and the right half of the sealing base cannot be effectively slidably connected to form a fixed effect, which reduces the quality of the plastic product and worsens the molding effect. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of the present invention is to provide a mold sealing structure for a plastic shell to solve the problem of mold sealing of the plastic shell.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A mold sealing structure for a plastic shell comprises a left semi-sealed base and a right semi-sealed base, wherein the left semi-sealed base is provided with two second fitting surfaces, a rectangular groove is provided in the center of the second fitting surface, a sliding mounting block is integrally formed in the interior of the rectangular groove, connecting grooves are provided on both sides of the surface of the second fitting surface, and a slope is provided on the inner wall of the connecting groove, wherein the right semi-sealed base is provided with two first fitting surfaces, sliders are integrally formed on both sides of the surface of the first fitting surface, a rectangular block is fixedly installed in the center of the first fitting surface, a sliding mounting groove is provided in the interior of the rectangular block, and the right semi-sealed base and the left semi-sealed base are snap-fitted together by the first fitting surface and the second fitting surface.

[0008] As a preferred technical solution, a left semi-circular hole is provided inside the left semi-sealed base, and a right semi-circular hole is provided inside the right semi-sealed base.

[0009] As a preferred technical solution, both sides of the interior of the sliding installation block are provided with clamping grooves, and both sides of the interior of the sliding installation groove are fixedly installed with clamping blocks.

[0010] As an optimal technical solution, the side walls of the connecting groove are provided with slopes, and both sides of the sliding block are provided with sliding oblique blocks.

[0011] As a preferred technical solution, the clamping block is clamped and connected inside the clamping groove to form a sliding installation, and a rectangular block is slidably installed inside the rectangular groove.

[0012] As an optimal technical solution, a sliding block is slidably connected inside the connecting groove, and the sliding bevel is fitted with the slope to form a sealing effect.

[0013] As a preferred technical solution, a plurality of through holes are provided on the surfaces of the right semi-sealed base and the left semi-sealed base, and a connecting slope is provided at one end of the connecting groove.

[0014] In summary, the present invention has the following beneficial effects:

[0015] The first is to align the rectangular block fixed inside the right half-sealed base with the rectangular groove opened inside the left half-sealed base during assembly, and then install the rectangular block into the rectangular groove by sliding. During the sliding installation, the sliding installation block installed inside the rectangular groove will form a snap-fitting effect with the sliding installation groove opened inside the rectangular block, which can effectively fix the right half-sealed base and the left half-sealed base, and can also increase the friction between the right half-sealed base and the left half-sealed base, which can effectively improve the fixing effect. When the rectangular block is slidably connected with the rectangular groove, the sliders installed on both sides of the fitting surface will also slide into the connecting groove opened inside the left half-sealed base, so that the connection between the right half-sealed base and the left half-sealed base can be sealed, thereby achieving an efficient sealing effect.

[0016] The inner wall of the connecting groove is provided with a slope and sliding oblique blocks are provided on both sides of the slider. The slope and the sliding oblique blocks form a fitting connection, which can effectively improve the strength and sealing effect of the seal. BRIEF DESCRIPTION OF THE DRAWINGS

The left semi-sealed base 2 is provided with two second fitting surfaces 23. A rectangular groove 25 is opened in the center of the second fitting surface 23. A sliding mounting block 27 is integrally formed inside the rectangular groove 25. Connecting grooves 24 are opened on both sides of the surface of the second fitting surface 23. The inner wall of the connecting groove 24 is provided with a slope 22. The right semi-sealed base 1 is provided with two first fitting surfaces 17. Sliders 16 are integrally formed on both sides of the surface of the first fitting surface 17. A rectangular block 14 is fixedly installed at the center of the first fitting surface 17. A sliding mounting groove 18 is opened in the interior of the rectangular block 14. The right semi-sealed base 1 and the left semi-sealed base 2 are snap-fitted together through the first fitting surface 17 and the second fitting surface 23.

[0025] refer to Figures 2 to 3 The left half-sealed base 2 is provided with a left half-base semicircular hole 21, and the right half-sealed base 1 is provided with a right half-base semicircular hole 12. Both sides of the interior of the sliding mounting block 27 are provided with snap-in grooves 26, and both sides of the interior of the sliding mounting groove 18 are fixedly installed with snap-in blocks 19. The snap-in blocks 19 are snap-connected to the inside of the snap-in groove 26 to form a sliding installation, and a rectangular block 14 is slidably installed inside the rectangular groove 25. The snap-in connection between the snap-in blocks 19 and the snap-in groove 26 can effectively improve the fixing effect of the left half-sealed base 2 and the right half-sealed base 1, prevent the left half-sealed base 2 and the right half-sealed base 1 from slipping, and improve the quality of the left half-sealed base 2 and the right half-sealed base 1.

[0026] refer to Figures 2 to 4 The side wall of the connecting groove 24 is provided with a slope 22, and sliding oblique blocks 13 are provided on both sides of the slider 16. The slider 16 is slidably connected inside the connecting groove 24, and the sliding oblique blocks 13 are fitted with the slope 22 to form a sealing effect. The inner wall of the connecting groove 24 is provided with a slope 22 and sliding oblique blocks 13 are provided on both sides of the slider 16. The slope 22 forms a fitting connection with the sliding oblique blocks 13, which can effectively improve the strength and sealing effect of the seal, and can also increase the friction so that the semi-sealed base and the right semi-sealed base 1 are firmly fixed together and will not fall off and cause quality problems of the plastic products.

[0027] refer to Figures 3 to 5 A plurality of through-holes 3 are provided on the surfaces of the right half-sealed base 1 and the left half-sealed base 2, and a connecting slope 28 is provided at one end of the connecting groove 24. When the left half-sealed base 2 and the right half-sealed base 1 are slidably connected, the connecting slope 28 can play an effective sliding effect, thereby increasing the installation speed of the left half-sealed base 2 and the right half-sealed base 1.

[0028] 2, and the left half-sealed base 2 is fixedly secured to the left half-sealed base 2. The right and left half-sealed bases 1 and 2 are fixed together, thereby improving the fixing effect and strengthening the connectivity. Since the right and left half-sealed bases 1 and 2 have a multi-layer connection structure, the friction force can be increased during sliding. In this way, the right and left half-sealed bases 1 and 2 will have a certain resistance during installation, which can prevent the right and left half-sealed bases 1 and 2 from sliding off the connection port, thereby effectively protecting the right and left half-sealed bases 1 and 2. A slope 22 is provided on the inner wall of the connecting groove 24, and sliding oblique blocks 13 are provided on both sides of the slider 16. The slope 22 forms a fitting connection with the sliding oblique blocks 13, which can effectively improve the sealing strength and sealing effect.
