DETAILED DESCRIPTION

[0022] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0023] like Figure 1 As shown, the injection molding machine's nozzle (not shown) is connected to an injection unit 4. A mold chamber 5 houses an openable and closable mold. The injection unit 4 drives the nozzle forward and applies high pressure to inject molten plastic into the mold cavity. After the mold is filled and cooled, the various plastic products are processed. After injection, the injection unit 4 drives the nozzle backward. Waste plastic carried by the nozzle can be dispersed. Furthermore, if the harmful gases emitted by the waste plastic are directly discharged, they can harm the environment and workers.

[0024] To solve the above problems, Figure 2 As shown, the present disclosure provides a cover device for an injection molding machine, which includes a first cover body 11 and a first exhaust pipe 21 connected to the first cover body 11. The first exhaust pipe 21 is connected to the air outlet 114 of the first cover body 11 and communicates with the inner cavity of the first cover body 11. The first cover body 11 is used to cover the nozzle of the injection molding machine. The exhaust gas at the nozzle can be collected through the first cover body 11 and the first exhaust pipe 21; and the first cover body 11 has baffles 111 located on both sides of the nozzle to provide glue injection protection. It should be noted that "the first cover body 11 is located above the nozzle" means that the dimensions of the first cover body 11 in the front-to-back direction can ensure that the nozzle is covered during the backward movement of the nozzle. In the vertical direction, the baffles 111 on both sides can extend below the nozzle to fully protect the glue injection.

[0025] In the cover device provided by the present invention, the injection molding protective cover and the waste gas collection cover are integrated into a design, and the two are combined into one, which simplifies the layout of the injection molding machine and has stronger integrity. The first cover 11 is arranged above the nozzle, and can absorb the harmful waste gas emitted when the waste glue flows out of the nozzle through the first cover 11 and the first exhaust pipe 21, thereby realizing the waste gas collection at the nozzle position. At the same time, a baffle 111 is provided on the first cover 11. The first cover 11 and the baffles 111 on both sides can cover the nozzle to prevent the waste glue brought out of the nozzle from spreading everywhere and splashing to other positions of the injection molding machine, thereby playing a role in protecting the injection molding.

[0026] In this disclosure, to facilitate the operator's observation of the nozzle's spraying conditions, an observation window 112 is provided on at least one of the baffles 111 located on either side of the nozzle. Observation window 112 is provided with transparent glass, which is removably mounted, allowing for cleaning and replacement whenever waste glue is splashed onto it. In this embodiment, observation windows 112 are provided on both baffles 111, allowing the operator to observe the nozzle's operating status from both sides. Of course, this disclosure also includes embodiments in which observation window 112 is provided on only one of the baffles 111.

[0027] The first cover body 11 can be of any appropriate structure. In the present disclosure, the first cover body 11 has a cover body 110, a cover opening 113 is provided at a position close to the nozzle of the cover body 110, an air outlet 114 is provided at a position away from the cover opening 113 of the cover body 110, and two baffles 111 are respectively provided on two opposite edges of the cover opening 113 of the cover body 110; the first exhaust pipe 21 is connected to the air outlet 114 of the cover body 110. The exhaust gas at the nozzle is sucked into the inner cavity of the cover body 110 through the cover opening 113, and enters the first exhaust pipe 21 through the air outlet 114. The suction process is similar to the suction process of a range hood, which can quickly collect the exhaust gas at the nozzle to prevent it from spreading outward.

[0028] In the disclosed embodiment, the cover body 110 can be a tapered structure that tapers from the cover opening 113 to the air outlet 114. The tapered design of the cover body 110 can converge the collected exhaust gas, funneling it into the first exhaust pipe 21. The baffles 111 on either side and the cover body 110 form a downward-facing U-shaped structure that prevents interference with the forward and backward movement of the nozzle driven by the injection device 4. The baffles 111 on either side and the cover body 110 can be integrally formed, or they can be removably mounted to the cover body 110 using screws or the like.

[0029] In the present disclosure, the first exhaust pipe 21 can be any pipeline connected between the air outlet 114 and the exhaust device (not shown in the figure). Under the suction force of the exhaust device, the exhaust gas in the first cover body 11 can be automatically transported to the exhaust device through the first exhaust pipe 21, which is convenient for centralized treatment.

[0030] Furthermore, if Figure 3As shown, the cover device provided by the present disclosure also includes a second cover 12 and a second exhaust pipe 22 connected to the second cover 12. The second cover 12 is used to collect the exhaust gas from the mold chamber 5 of the injection molding machine. The second exhaust pipe 22 is connected to the first exhaust pipe 21. The exhaust gases collected by the second cover 12 and the first cover 11 are mixed and collected. The second exhaust pipe 22 is connected to the air outlet of the second cover 12 and is connected to the inner cavity of the second cover 12. The exhaust gas from the mold chamber 5 enters the second exhaust pipe 22 through the inner cavity and air outlet of the second cover 12. Its suction principle is similar to that of the first cover 11. The cover device can simultaneously collect the exhaust gas escaping from the mold chamber 5 and the exhaust gas at the nozzle. The two covers share the same exhaust device, saving pipeline layout, realizing the integrated design of the injection protection cover, the exhaust gas collection cover at the nozzle, and the exhaust gas collection cover of the mold chamber, further improving the integrity.

[0031] According to a second aspect of the present disclosure, an injection molding machine is provided, which includes the cover device described above. The injection molding machine has all the beneficial effects of the cover device described above, which will not be repeated here.

[0032] like Figure 1 As shown, the injection molding machine includes a base 3, an injection device 4 provided on the base 3, and a mold chamber 5 provided on one side of the base 3. In the related art, the exhaust pipe of the exhaust gas collection cover at the mold chamber 5 is arranged upward, occupying the space at the top of the injection molding machine. In order to solve the above problem, in the present disclosure, as shown in FIG. Figure 1 As shown, the first cover body 11 is arranged vertically with the cover opening 113 of the first cover body 11 facing downward; the second cover body 12 is provided at the top opening of the mold chamber 5 and arranged laterally. Here, "lateral arrangement" means that the second cover body 12 is arranged horizontally with the cover opening of the second cover body 12 facing the side where the first cover body 11 is located, or the second cover body 12 is arranged on the side of the mold chamber 5 with the cover opening facing the interior of the mold chamber 5. The exhaust gas collection cover at the mold chamber 5 is adjusted to the top side of the injection molding machine, and the second cover body 12 is arranged laterally and horizontally. Accordingly, the second exhaust pipeline 22 runs downward and does not occupy the top space of the injection molding machine.

[0033] In an exemplary embodiment, Figure 1 As shown, the first exhaust pipe 21 has a first horizontal section 211, a vertical section 212 and a second horizontal section 213 connected in sequence. The first horizontal section 211 is connected to the air outlet 114, and the second horizontal section 213 is used to connect to the exhaust device. The two connected pipe sections can be connected by an elbow. The first horizontal section 211 and the second exhaust pipe 22 of the first exhaust pipe 21 are located above the mold chamber 5. The vertical section 212 of the first exhaust pipe 21 is arranged parallel to the side wall of the mold chamber 5, and the second horizontal section 213 of the first exhaust pipe 21 extends into the interior of the base 3.

[0034] In the present disclosure, an exhaust device is disposed within the base 3, on a side away from the mold chamber 5. The second horizontal section 213 of the first exhaust pipe 21 passes through the interior of the base 3 and is connected to the exhaust device. The base 3 and the mold chamber 5 can be arranged in a front-to-back direction. The exhaust device is disposed within the inner cavity of the base 3 and is located at the rear end. The exhaust gas collected at the nozzle and the exhaust gas collected at the mold chamber 5 are combined and then pass through the internal space of the base 3 to the rear end of the injection molding machine, thereby freeing up the upper space of the injection molding machine.

[0035] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced. In this regard, terms indicating directions or expressing positional relationships, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., may be used with reference to the orientation of the figures being described. Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0036] It should be understood that, unless otherwise specifically noted, the features of the various embodiments of the present disclosure described herein may be combined with each other. As used herein, the term "and / or" includes any one of the relevant listed items and any combination of any two or more thereof; similarly, "at least one of" includes any one of the relevant listed items and any combination of any two or more thereof.

[0037] It should be understood that, unless otherwise expressly specified or limited, the terms "join," "attach," "install," "connect," "connect," "fix," etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or communicable with each other; they can be directly connected, or indirectly connected through an intermediate medium, and they can be internally connected between two elements or an interactive relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0038] Additionally, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may be used herein to mean that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0039] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0040] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0041] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0042] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. With particular regard to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if not structurally equivalent to the disclosed structure. In addition, although particular features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms "include," "have," "have," "have," or variations thereof are used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "comprising."

[0043] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.

[0044] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof.
