Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for producing buttons and lampshades. Background Art
[0002] Injection molding refers to a method in which a heated and molten material is injected into a mold cavity by high pressure, and after cooling and solidification, a formed plastic product is obtained. This method is suitable for mass production of plastic products and is one of the important plastic processing methods. Injection mold (Mold) refers to a device that injects resin or plastic material into a metal model to obtain a product with a certain shape. In production operations, in order to control the temperature of the mold, there are cooling holes, heaters and other devices on the mold to allow refrigerants (warm water or oil) to pass through. Among them, the material that has become a melt enters the main channel, passes through the branch channel, and is injected into the mold cavity through the gate. After the cooling stage, the mold is opened, and the ejector device on the molding machine will use the ejector rod to eject the plastic product.
[0003] A set of injection molds usually consists of mold frame system, mold core system, pouring system, ejection system, side core pulling system, cooling system, exhaust system, support system, limit system and mold opening control system, etc. Each system is composed of different parts, and each system is closely related to each other in production.
[0004] When some devices require both button products and lampshade products, they usually need to be injection molded separately, which leads to high costs. Some button products are also designed with mounting columns, mounting holes and limit blocks. Traditional injection molds are not convenient for injection molding and require secondary processing to obtain the final plastic product.
[0005] Therefore, how to use the same injection mold to injection mold both lampshade products and button products, and obtain the final plastic product in one injection molding, is a technical problem that needs to be solved. Utility Model Content

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. 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.
[0031] See also Figures 1 to 6 In an embodiment of the utility model, an injection mold for producing buttons and lampshades includes a mold frame assembly 10, a mold core assembly 20, an ejector assembly 51, a pouring system 52 and a cooling system 53. The mold core assembly 20 is fixedly connected to the inside of the mold frame assembly 10 and forms a cavity for the injection molded product. The pouring system 52 is used to inject plastic heat flow into the cavity. The cooling system 53 is used to cool the plastic product. The ejector assembly 51 is used to eject the product after the mold is demolded; the mold core assembly 20 includes a lower mold core 21 and an upper mold core 40. The lower mold core 21 is provided with a strip insert 22. One end of the strip insert 22 is fixedly connected to the lower mold core 21, and the other end thereof is formed with a strip protrusion 23. The strip protrusion 23 extends into the cavity for a certain distance; the upper mold core 40 is provided with a strip groove 41. The strip protrusion 23 cooperates with the strip groove 41 to form a lampshade product 60 by injection molding.
[0032] Specifically, in order to form an arched appearance of the injection-molded lampshade product 60, a corresponding strip insert 22 can be provided on the lower mold core 21, and a strip protrusion 23 at one end of the strip insert 22 is extended a certain distance in the cavity inside the mold, thereby forming an insert protruding in the cavity, so that the plastic heat flow can form an arched shape on the strip protrusion 23. Correspondingly, a strip groove 41 matching the strip protrusion 23 can also be provided on the upper mold core 40, thereby forming a complete cavity of the injection-molded lampshade.
[0033] Secondly, the ejection assembly 51, the pouring system 52 and the cooling system 53 can all be set up using the relevant injection molding technology in the prior art. Of course, certain modifications are required according to the specific injection molding products. For example, the ejection rod of the ejection assembly 51 needs to cooperate with the button product 61 and the lampshade product 60 for ejection. The pouring system 52 needs to add a gate so that multiple plastic products can be poured inside a mold core assembly 20. The cooling pipes of the cooling system 53 should also be adjusted accordingly so that multiple plastic products can be cooled and shaped. In addition, corresponding panels, base plates, square irons and other supporting devices can be set in the injection mold, and corresponding installation and activation can be carried out. Since the relevant technology can be the prior art, it will not be repeated here.
[0034] like Figure 4 and Figure 5 As shown, preferably, the upper mold core 40 is further provided with a square groove 42, and the square groove 42 is used for injection molding a key cap 62 of a key product 61. The lower mold core 21 is further provided with an annular countersunk hole 24, and the annular countersunk hole 24 is used for injection molding a mounting column 63 of the key product 61. The lower mold core 21 is further provided with a side slider 30, and the side slider 30 is provided with an annular groove 31, and the annular groove 31 cooperates with the annular countersunk hole 24 to form the mounting column 63 of the key product 61 by injection molding.
[0035] Specifically, for the injection molding of the key product 61, corresponding settings can be made according to the key cap 62 and the mounting column 63 below. For example, a square groove 42 matching the key cap 62 is set on the upper mold core 40, and an annular countersunk hole 24 matching the mounting column 63 is set on the lower mold core 21, and then the annular groove 31 on the side slider 30 and the annular countersunk hole 24 are connected to each other to form a circular cavity. Finally, the square groove 42 and the circular cavity are combined to form a complete cavity of the injection molded key product 61.
[0036] like Figure 4 and Figure 5 As shown, preferably, the lower mold core 21 is also provided with a columnar insert 26, one end of the columnar insert 26 is fixedly connected in the lower mold core 21, and the other end thereof is formed with a columnar protrusion 27, and the columnar protrusion 27 extends into the annular countersunk hole 24 for a certain distance, thereby injection molding a mounting hole 64 inside the mounting column 63.
[0037] Specifically, for the mounting hole 64 on the mounting column 63 of the button product 61, a corresponding columnar insert 26 needs to be set, and the columnar protrusion 27 at one end thereof is inserted into the annular countersunk hole 24, thereby forming a corresponding shape and position in the cavity, so that the plastic heat flow can form the mounting hole 64 during injection molding.
[0038] like Figures 3 to 5As shown, preferably, a notch 25 is provided on one side of the annular countersunk hole 24 , and the notch 25 is used to form a limiting block 65 on the outer side of the mounting column 63 by injection molding.
[0039] Specifically, for the limit block 65 on the mounting column 63, a matching notch 25 can be set on the annular countersunk hole 24, and the notch 25 is used to form an injection molding cavity with a certain gap, so that the casting system 52 can inject the plastic heat flow into the notch 25, thereby forming the limit block 65 on the mounting column 63.
[0040] like Figure 1 , Figure 2 and Figure 6 As shown, preferably, the mold frame assembly 10 includes a lower mold frame 11 and an upper mold frame 13, the side slider 30 is provided with an inclined hole 32, and the upper mold frame 13 is provided with an inclined guide column 14, one end of the inclined guide column 14 is fixedly connected in the upper mold frame 13, and the other end thereof is inserted into the inclined hole 32 to form a sliding connection, thereby driving the side slider 30 to move a certain distance. The lower mold frame 11 is provided with a side slide groove 12, and the side slider 30 cooperates with the side slide groove 12 to form a sliding connection.
[0041] Specifically, because the limit block 65 is provided on the mounting column 63, when the upper mold frame 13 and the upper mold core 40 are directly opened, the limit block 65 will be blocked by the side slider 30, so the side slider 30 needs to be moved away first. It is preferred to set an inclined guide column 14 and an inclined hole 32, and use the kinetic energy of the upper mold frame 13 when opening the mold, so that the inclined guide column 14 forms a driving force on the inclined hole 32, so that the inclined hole 32 drives the side slider 30 to move to both sides of the mold, thereby avoiding the limit block 65. In order to make the side slider 30 move more smoothly and accurately, a side slide groove 12 can also be provided on the lower mold frame 11, so that a sliding fit is formed between the side slider 30 and the side slide groove 12.
[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
