Description

Technical Field

[0001] The utility model mainly relates to the technical field of 3D cover plate processing, and in particular to a double-cavity mold for 3D cover plates. Background Art

[0002] As the automotive industry continues to develop with autonomous driving, electrification and informatization, the screen size of vehicle displays will become larger and the shapes more complex. 3D cover panels are bound to become a development trend. Therefore, the most common C-type glass on the market will be in greater demand and have higher dimensional contour requirements.

[0003] At present, most C-type cover plate processes use high energy output from the lamp tube to form the glass naturally when the glass reaches the softening point, and the mold has only one hole. This method results in a slow glass forming speed; only one piece of glass is output each time, which is inefficient; and the requirements for the contour and flatness of this type of glass are relatively low, and it is impossible to break through and meet the requirements of high-standard products.

On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] For examples, please refer to the attached Figure 1-4 A double-cavity mold for a 3D cover plate comprises a mold body 10, wherein the upper surface of the mold body 10 is connected to two positioning edges 20, and the positioning edges 20 are connected end to end to form a cavity 30;

[0026] The inner surface of the positioning edge 20 is connected with a positioning block 21;

[0027] The cavity 30 is provided with a plurality of vacuum holes 31 in an array. The ends of the cavity 30 that are away from each other are provided with measuring holes 32. The measuring holes 32 are provided on the shell of the mold body 10. A switching component 33 is provided at one end of the measuring holes 32.

[0028] For details, please refer to the attached Figure 2 and 3 The bottom end of the mold body 10 is provided with a transport groove 11, and the plurality of transport grooves 11 respectively correspond to the bottom ends of the mold body 10;

[0029] The vacuum holes 31 in each of the cavities 30 are connected via a vacuum path 35;

[0030] The inner surface of the positioning edge 20 is provided with a groove 22, and the groove 22 is used for the positioning block 21 to fit in;

[0031] It should be noted that, in this embodiment, grooves of the same size are dug at the four corners of the mold as the transport grooves 11 to facilitate employees to transport the mold;

[0032] Furthermore, the plurality of vacuum holes 31 are connected through the vacuum path 35, thereby reducing the number of air pumps and saving costs.

[0033] Furthermore, each cavity 30 accommodates a positioning block 21 through a groove 22, and the positioning blocks 21 of each cavity are on the same side, which can prevent people from putting glass in and play a role in positioning the glass.

[0034] For details, please refer to the attached Figure 3 and 4 The measuring hole 32 is connected to the interior of the adjacent cavity 30, and a thread is provided in the hole body at one end of the measuring hole 32;

[0035] A temperature measuring tube 34 is provided in the cavity 30, and the temperature measuring tube 34 is connected to the measuring hole 32;

[0036] The switching assembly 33 includes a three-way blocking ball 331 rotatably connected to one end of the measuring hole 32, a rotating shaft connected to the three-way blocking ball 331, a worm gear 333 connected to one end of the rotating shaft extending outside, and a worm 332 meshing with the worm gear 333, and the worm gear 332 is rotatably connected to the outside of the mold body 10;

[0037] It should be noted that, in this embodiment, the measuring hole 32 is connected to the barometer and the thermometer through threads. Since the measuring hole 32 is connected to the cavity 30 through the temperature measuring tube 34, the temperature and air pressure in the cavity 30 are measured.

[0038] Furthermore, by rotating the worm 332, the worm wheel 333 meshing with the worm 332 is driven. Since the worm wheel 333 is coaxially arranged with the three-way sealing ball 331, the three-way sealing ball 331 is driven to rotate, so as to determine whether the measuring hole 32 is connected with the vacuum path 35, and then choose whether to measure the negative pressure adsorption capacity of the mold. In this process, a handwheel can be set at one end of the worm 332 for manual rotation, or a motor can be set for automatic rotation. A self-locking structure is formed by the cooperation of the worm 332 and the worm wheel 333 to prevent the three-way sealing ball 331 from rotating automatically due to external interference.

[0039] The specific operation mode of the utility model is as follows:

[0040] The mold body 10 is placed on the machine. The employee can cast two pieces of glass in the direction of the positioning block 21 in each round. According to the glass molding state and standard requirements, the negative pressure suction force generated by the vacuum hole 31 is combined with the cavity 30 to improve the free negative pressure adjustment in three parts.
