Description

Technical Field

[0001] The utility model relates to the technical field of lamp production, in particular to a lamp panel production mold. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, lamps play an increasingly important role in the field of interior decoration and lighting. At present, the panels of lamps are generally injection molded in the production process. The lamp mold technology mainly involves injection molding, die casting, extrusion molding and other methods of plastic, metal and other materials.

[0003] At present, the design of injection molds for lamp panels is mainly based on the design requirements of the product. At present, most molds are only well adapted to the outer buckle position. Due to the need for forming buckle positions on some front parts of the product, as shown in the figure in the manual, Figure 4 The lamp panel structure shown needs to have four buckle positions formed on the inner side of the front surface. Therefore, it is difficult for a traditional injection mold structure to realize the mold after the buckle positions on the front surface are formed, thus causing inconvenience in actual production. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art such as being unable to adapt to products that require forming buckles on part of the front surface, and to propose a lamp panel production mold.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A lamp panel production mold is designed, comprising an upper mold unit and a lower mold unit, wherein the upper mold unit comprises an upper plate and an upper mold base disposed below the upper plate, wherein a mold core is disposed inside the upper mold base;

[0007] A cavity is provided on the inner side of the upper mold base, in which a ejector plate slides, and a slanted ejector assembly is provided at the bottom of the ejector plate. At least part of the slanted ejector assembly is passed through the bottom of the mold core for buckling and molding the product.

[0008] Furthermore, a slide plate is provided in the cavity, and the slide plate is fixedly connected to the ejector plate, wherein a guide rod penetrating the slide plate is fixed in the cavity.

[0009] Furthermore, a plurality of elastic members are fixed between the ejector plate and the inner wall of the cavity.

[0010] Furthermore, the inclined ejector assembly includes several slides fixed below the ejector plate, and an inclined ejector rod is slidably connected to the bottom of the slide. An inclined hole is provided inside the mold core, and the inclined ejector rod is slidably connected to the inclined hole.

[0011] Furthermore, a T-shaped slot is provided at the bottom of the slide seat, a T-shaped slider is fixed to the top of the inclined ejector rod, and the T-shaped slider slides in the T-shaped slot.

[0012] Furthermore, a water cooling pipe is provided inside the mold core, and the water cooling pipe is used to be connected to an external circulating cooling device.

[0013] The utility model proposes a lamp panel production mold, which has the beneficial effect that: the utility model sets a pin plate structure inside the upper mold unit, adopts an inclined ejection method to form the buckle position on the front of the product, and after forming, the inclined ejector moves and releases, so as to solve the problem of inconvenience in forming the buckle position on the front of some products. During operation, multiple inclined ejectors cooperate with the same mold core and can therefore move simultaneously, thereby ensuring the consistency of the release action when the mold is separated, thereby effectively improving the buckle position molding quality.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 This is an embodiment of the present invention, which discloses a lamp panel production mold. Specifically, the mold described in this embodiment includes an upper mold unit 1 and a lower mold unit 2. The lower mold unit 2 can adopt an existing lower mold structure and will not be described in detail here. In this embodiment, the upper mold unit 1 includes an upper plate 11 and an upper mold base 12 arranged below the upper plate 11. A mold core 13 is arranged inside the upper mold base 12.

[0021] A cavity is provided on the inner side of the upper mold base 12, in which a ejector plate 3 slides. A slanted ejector assembly 4 is provided at the bottom of the ejector plate 3, and at least a portion of the slanted ejector assembly 4 is passed through the bottom of the mold core 13 for buckling and molding the product 5.

[0022] In some embodiments, a slide plate 31 is further provided in the cavity of the utility model, and the slide plate 31 is fixedly connected to the ejector plate 3, wherein a guide rod 32 penetrating the slide plate 31 is fixed in the cavity. Preferably, several guide rods 32 described in this embodiment can be provided. Through the design of the guide rod 32 and the slide plate 31, the ejector plate 3 can slide inside the cavity, so as to adjust the position of the ejector plate 3 when the mold is parted.

[0023] Furthermore, in this embodiment, a plurality of elastic members 33 are fixed between the ejector plate 3 and the inner wall of the cavity. The elastic members 33 are configured as springs. Through the elastic force of the springs, after the demolding is completed, the ejector plate 3 can be controlled to reset, thereby driving the entire inclined ejector assembly 4 to reset to its initial position.

[0024] On the basis of the above embodiment, the inclined ejector assembly 4 includes a plurality of slides 41 fixed under the ejector plate 3, and the slides 41 are preferably arranged in four, and the four slides 41 are distributed in a matrix for realizing the four-side molding of the product 5. A inclined ejector rod 42 is slidably connected to the bottom of the slide 41, and an inclined hole is provided inside the mold core 13. The inclined ejector rod 42 is slidably connected to the inclined hole. Since the mold core 13 is provided with an inclined hole inside, when the mold core 13 moves up and down relative to the inclined ejector rod 42, the inclined ejector rod 42 can be driven to move. Specifically, this movement mode is achieved through the guide cooperation between the slide 41 and the inclined ejector rod 42.

[0025] On the basis of the above embodiment, a T-slot 411 is provided at the bottom of the slide 41 in the utility model, and a T-slider is fixed to the top of the inclined push rod 42, and the T-slider slides in the T-slot 411. Through the design adaptation of the T-slot 411 and the T-slider, the inclined push rod 42 can be guided and limited, thereby avoiding the problem of the inclined push rod 42 slipping off the slide 41.

[0026] Of course, considering the rapid cooling of the product 5 after molding, a water cooling pipe 14 is further provided inside the mold core 13 in this embodiment. The water cooling pipe 14 is used to connect to an external circulating cooling device. The cooling device is a circulating cooling water supply device. The circulating cooling water is used to reduce the temperature of the mold core 13, thereby improving the cooling efficiency of the product 5.

[0027] During mold separation, the upper plate 11 drives the mold core 13 to move first. At this time, the position of the ejector plate 3 is controlled to remain unchanged. After the mold core 13 moves, the inclined ejector rod 42 is driven to move inward and retract through the inclined hole inside it. This action completes the disconnection from the product 5. After the disconnection is completed, the upper plate 11 and the ejector plate 3 are normally separated. Under the action of the elastic member 33, the ejector plate 3 is driven to reset to control the reset of multiple inclined ejector rods 42 to complete the demolding action of the upper mold unit 1. The lower mold unit 2 can adopt a conventional mold structure, which will not be elaborated here.

[0028] In summary, in the present invention, a pin plate 3 structure is set inside the upper mold unit 1, and the buckle position on the front of the product 5 is formed by an inclined ejection method. After forming, the inclined ejector rod 42 moves and disengages to solve the problem of inconvenience in forming the buckle position on the front of some products 5. During operation, multiple inclined ejector rods 42 cooperate with the same mold core 13, so they can move simultaneously, thereby ensuring the consistency of the disengagement action when the mold is separated, thereby effectively improving the buckle position molding quality.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
