[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the refrigerator manufacturing industry, the design and application of door liner molding molds are important links to ensure the performance and appearance quality of refrigerators. Traditional refrigerator door liner molding molds usually rely on auxiliary mold mechanisms to achieve the molding of door seals. Although this method can meet production needs to a certain extent, it also has some significant defects. The use of auxiliary molds increases the complexity and manufacturing cost of the mold. The auxiliary molds not only require additional materials and processing technology, but also require precise docking and adjustment during the production process, which invisibly increases the production cycle and labor costs.

[0030] Embodiment 1:

[0031] Since the existing molds here need to use auxiliary molds to form the structure, they cannot be used on some molding machines that cannot install auxiliary molds. In order to solve the above problems, combined with Figure 1-Figure 3 As shown, the present invention provides a refrigerator door liner molding mold door seal molding non-auxiliary mold mechanism, which is provided with a door seal molding mechanism 2 as a carrier of the entire device, a base 3 is installed on the door seal molding mechanism 2, and a main body 1 is provided on the base 3, which solves the design of the refrigerator door liner peripheral door seal installation groove being made by vacuum forming without an auxiliary mold;

[0032] Since the coordination requirements between the auxiliary mold and the main mold are extremely high, any slight error may lead to poor door seal molding. This precision problem may affect the sealing performance of the refrigerator, and further affect the energy efficiency and product quality. In order to solve the above problems, the base 3 includes door seal mounting grooves installed on the two side walls of the door seal molding mechanism 2, and a plurality of cylinders 7 are also installed in the door seal molding mechanism 2. A clamp 8 for fixing the door seal mounting groove is provided on the base 3.

[0033] Specifically, the door seal installation groove is composed of a door seal outer slide bar 4 , a door seal fixing strip 5 and a door seal inner slide bar 6 , and the door seal outer slide bar 4 and the door seal inner slide bar 6 are respectively located on both sides of the door seal fixing strip 5 .

[0034] According to the embodiment, the cylinder 7 is opened and closed to control the back and forth movement of the door seal outer slide 4 and the door seal inner slide 6 components. When the mechanism is working, the door seal outer slide 4 and the door seal inner slide 6 are in an open state. When the door seal is formed, the cylinder 7 is used to close them and ensure the specified size. This design allows more plates to participate in the forming and stretching to ensure the forming wall thickness of the door seal groove.

[0035] Embodiment 2:

[0036] When the mold volume is large, insufficient number of cylinders 7 may lead to uneven pressure distribution, affecting the molding effect. In order to solve the above problem, combined with Figure 2 As shown, on the basis of the first embodiment, the door seal fixing strip 5 is fixed on the base 3, and the two movable components of the door seal outer slide strip 4 and the door seal inner slide strip 6 are installed on the cylinder 7 below.

[0037] Specifically, a plurality of cylinders 7 are provided, and the number of cylinders 7 is adjusted according to the size of the product.

[0038] Furthermore, a large number of vacuum holes are arranged in the door seal installation groove, so that the door seal can be formed without an auxiliary mold.

[0039] Embodiment three:

[0040] Since traditional fixing methods (such as screws, glue, etc.) usually require additional tools and steps, which increases the complexity of installation and may lead to insufficient connection strength and easy loosening, in order to solve the above problems, combined with Figure 4-Figure 8As shown, on the basis of Example 1, the clamp 8 includes a plurality of support seats 801 fixedly connected to the base 3, a piston 802 is slidably connected to the support seat 801, blocks 803 are slidably connected to both sides of the support seat 801, a transmission bar 804 is hinged between the piston 802 and the block 803, a plurality of grooves 805 are provided on the outer sides of the door seal outer sliding bar 4 and the door seal fixing bar 5, the ends of the blocks 803 are inserted into the corresponding grooves 805, and the piston 802 and the blocks 803 are connected by the hinged transmission bar 804, which can effectively transmit force and ensure that during the molding process, each part of the door seal can be evenly stressed to avoid deformation, thereby improving the molding accuracy.

[0041] Load-bearing plates 10 are fixedly connected on both sides of the base 3, and an electric push rod 12 is fixedly installed on the load-bearing plate 10. A connecting plate 14 is fixedly connected to the free end of the electric push rod 12. Connecting strips 13 are fixedly connected on both sides of the connecting plate 14. An insert block 11 is fixedly connected to the connecting strip 13 near the main body 1. A slot 9 corresponding to the insert block 11 is opened on the outside of the main body 1. The insert block 11 is inserted into the slot 9, which ensures the firmness of the connection and avoids loose connection due to vibration or other factors during operation, thereby ensuring the safety and stable operation of the equipment.

[0042] A serpentine flow channel 15 is provided at the bottom of the main body 1, and a guide tube 16 for absorbing heat is fixedly connected to the serpentine flow channel 15. Both ends of the guide tube 16 are respectively connected to external water pipes, which increases the contact area between the fluid and the cooling medium, helps to improve the heat exchange efficiency, and thus effectively absorbs the heat generated by the main body 1.

[0043] The serpentine arrangement ensures that the cooling medium can flow evenly, avoids local overheating, ensures that the temperature of the entire system remains within a stable range, and extends the service life of the equipment.

[0044] An air pump is fixedly installed in the base 3, and the air pump is connected to the support base 801 through a pipeline, and is used to control the piston 802 to rise and fall.

[0045] The blister forming of refrigerator door liner is usually done by heating and softening a plastic sheet, attaching it to the surface of a mold in the shape of the door liner by vacuum suction, forming it inside the mold and cooling and solidifying it to finally form the door liner. The blister forming method of this mechanism is the same as the previous one, but improvements have been made in other aspects. By optimizing the design of the door seal installation groove, it can achieve blister forming without an auxiliary mold, ensuring that the molded product meets the requirements.

[0046] From the above embodiments, it can be seen that when the mold is formed, the door seal groove is first in an open state, so that more plates can participate in the forming stretching to ensure the forming wall thickness of the door seal groove. Because there are a large number of vacuum holes, the door seal can be formed without an auxiliary mold.

[0047] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
