Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with an automatic waste collection function. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] However, traditional injection molds typically require manual cleaning of residual edge waste on the mold surface after molding. This process presents several problems: manual waste cleaning requires interrupting the production line, increasing the production cycle, especially in mass production where efficiency is significantly reduced; long-term reliance on manual operation not only increases manpower input but may also lead to inconsistent cleaning results due to differences in operator proficiency; furthermore, the high temperature of the mold immediately after injection makes manual cleaning prone to burns and other safety accidents; and the waste collected during manual cleaning is easily scattered, hindering centralized recycling and reuse, resulting in material waste. Therefore, we propose an injection mold with an automatic waste collection function to solve these existing problems. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold with an automatic waste collection function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold with automatic waste collection function, including a base, a mounting plate, a first telescopic cylinder, a fixing rod, a fixing frame, a waste bin, a second telescopic cylinder, an upper mold, and a lower mold. The base is fixedly connected to the four corners of the base, and the mounting plate is fixedly connected to the side of the base away from the fixing rod. The first telescopic cylinder is fixedly connected to the mounting plate, and the upper mold is fixedly connected to the output end of the first telescopic cylinder. A fourth telescopic cylinder is fixedly connected to the bottom of the base, and a third telescopic cylinder is fixedly connected to one side of the base with respect to the fourth telescopic cylinder.

[0006] Preferably, the output end of the fourth telescopic cylinder is fixedly connected to a second movable component, and the fourth telescopic cylinder is movably connected to the lower mold through the second movable component. The output end of the third telescopic cylinder is fixedly connected to a first movable component, and the third telescopic cylinder is movably connected to one side of the lower mold through the first movable component.

[0007] Preferably, a fixing frame is fixedly connected to the fixing rod, a second telescopic cylinder is fixedly connected to one side of the fixing frame, and a push plate is fixedly connected to the output end of the second telescopic cylinder.

[0008] Preferably, a waste bin is fixedly connected to one side of the base, the lower mold and the waste bin cooperate with each other, and the upper mold and the lower mold cooperate with each other.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. After the injection molded part cools and solidifies, it enters the demolding and waste collection process. The first telescopic cylinder retracts, driving the upper mold to move upward and separate from the lower mold, exposing the molded injection part and edge waste. The third telescopic cylinder pulls one side of the lower mold downward through the first movable part. The fourth telescopic cylinder pushes the other side of the lower mold upward through the second movable part, so that the lower mold as a whole tilts towards the waste bin.

[0011] 2. The second telescopic cylinder fixed on the fixed frame is activated, and its output end pushes the push plate to move closer to the lower mold, pushing the residual waste on the lower mold towards the inclined edge of the lower mold. The waste slides down the inclined surface of the lower mold and finally falls into the waste box on one side of the base, completing the automatic collection. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figures 1-4As shown, the injection mold with automatic waste collection function proposed in this utility model includes a base 1, a mounting plate 2, a first telescopic cylinder 3, a fixing rod 4, a fixing frame 5, a waste bin 6, a second telescopic cylinder 7, an upper mold 8, and a lower mold 9. The four corners of the base 1 are fixedly connected to the fixing rod 4. The mounting plate 2 is fixedly connected to the side of the base 1 away from the fixing rod 4. The first telescopic cylinder 3 is fixedly connected to the mounting plate 2. The output end of the first telescopic cylinder 3 is fixedly connected to the upper mold 8. The fourth telescopic cylinder 12 is fixedly connected to the bottom of the base 1. The third telescopic cylinder 11 is fixedly connected to one side of the base 1 and the fourth telescopic cylinder 12.

[0019] When the upper mold 8 and the lower mold 9 are separated, the first telescopic cylinder 3 is activated, and its output end pushes the upper mold 8 downward until the upper mold 8 and the lower mold 9 are precisely closed to form a closed injection cavity. Molten plastic is injected into the closed cavity through the nozzle of the injection molding machine. After injection, a certain pressure is maintained to ensure that the plastic fills the cavity and cools and solidifies.

[0020] In an optional embodiment, the output end of the fourth telescopic cylinder 12 is fixedly connected to the second movable member 14, and the fourth telescopic cylinder 12 is movably connected to the lower mold 9 through the second movable member 14. The output end of the third telescopic cylinder 11 is fixedly connected to the first movable member 13, and the third telescopic cylinder 11 is movably connected to one side of the lower mold 9 through the first movable member 13.

[0021] After the injection molded part cools and solidifies, it enters the demolding and waste collection process. The first telescopic cylinder 3 retracts, driving the upper mold 8 to move upward and separate from the lower mold 9, exposing the molded injection part and edge waste. The third telescopic cylinder 11 pulls one side of the lower mold 9 downward through the first movable part 13, and the fourth telescopic cylinder 12 pushes the other side of the lower mold 9 upward through the second movable part 14, so that the lower mold 9 as a whole tilts towards the waste bin 6.

[0022] In an optional embodiment, a fixing frame 5 is fixedly connected to the fixing rod 4, a second telescopic cylinder 7 is fixedly connected to one side of the fixing frame 5, and a push plate 10 is fixedly connected to the output end of the second telescopic cylinder 7.

[0023] The second telescopic cylinder 7, fixed on the fixed frame 5, is activated. Its output end pushes the push plate 10 to move closer to the lower mold 9, pushing the waste material remaining on the lower mold 9 towards the inclined edge of the lower mold. The waste material slides down the inclined surface of the lower mold and finally falls into the waste box 6 on one side of the base 1, completing the automatic collection.

[0024] In an optional embodiment, a waste bin 6 is fixedly connected to one side of the base 1, the lower mold 9 and the waste bin 6 cooperate with each other, and the upper mold 8 and the lower mold 9 cooperate with each other.

[0025] The working principle of this utility model is as follows: When using this device, in the initial state, the upper mold 8 and the lower mold 9 are separated. The first telescopic cylinder 3 is started, and its output end pushes the upper mold 8 downward until the upper mold 8 and the lower mold 9 are precisely closed to form a closed injection cavity. The molten plastic is injected into the closed cavity through the nozzle of the injection molding machine. After the injection is completed, a certain pressure is maintained to ensure that the plastic fills the cavity and cools and solidifies.

[0026] After the injection molded part cools and solidifies, it enters the demolding and waste collection process. The first telescopic cylinder 3 retracts, driving the upper mold 8 to move upward and separate from the lower mold 9, exposing the molded injection part and edge waste. The third telescopic cylinder 11 pulls one side of the lower mold 9 downward through the first movable part 13, and the fourth telescopic cylinder 12 pushes the other side of the lower mold 9 upward through the second movable part 14, so that the lower mold 9 as a whole tilts towards the waste bin 6.

[0027] The second telescopic cylinder 7, fixed on the fixed frame 5, is activated. Its output end pushes the push plate 10 to move closer to the lower mold 9, pushing the waste material remaining on the lower mold 9 towards the inclined edge of the lower mold. The waste material slides down the inclined surface of the lower mold and finally falls into the waste box 6 on one side of the base 1, completing the automatic collection.

[0028] The push plate 10 is reset under the retraction of the second telescopic cylinder 7, and the third and fourth telescopic cylinders 11 and 12 work together to drive the lower mold 9 back to a horizontal state; the first telescopic cylinder 3 pushes the upper mold 8 to close again, and enters the next injection cycle.

[0029] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof.
