[0044] Although the invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0045] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0046] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, etc.) are used to explain the structure and movement of the various elements of the invention and are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0047] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of the invention will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0048] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, one embodiment of the present invention provides a plastic injection mechanism 100, which is applied to an injection molding machine to heat and plasticize plastic and then inject molten plastic into a mold cavity under certain pressure and speed.

[0050] The injection mechanism 100 includes a base 110, an injection tail plate 120, an injection head plate 130, and an adjustment structure 140. The base 110 defines a first mounting position 111 and a second mounting position 112 arranged at intervals along a first direction x. The base 110 can be designed into any shape according to actual needs, such as rectangular or circular, which will not be described in detail here.

[0051] Regarding the first mounting position 111, it should be noted that it is the area on the base 110 used for mounting the injection tail plate 120. This area can be enclosed by a specific groove, protrusion, or other structure, or it can be a planar area on the base 110 without any enclosed structure. In one specific embodiment, the injection tail plate 120 is slidably mounted on the base 110, wherein the base 110 is provided with a corresponding slide rail 1111, which defines the first mounting position 111.

[0052] Similarly, it should be noted that the second mounting position 112 is the area on the base 110 used to mount the injection head plate 130. It can be an area enclosed by a specific groove, protrusion or other structure, or it can be a planar area on the base 110 without any solid structure.

[0053] The injection tail plate 120 is disposed at the first mounting position 111, and the injection head plate 130 is disposed at the second mounting position 112. A gap d exists between the injection head plate 130 and the second mounting position 112 in the second direction y, where the second direction y is inclined or perpendicular to the first direction x. The gap d provides the injection head plate 130 with room to move in the second mounting position 112, allowing the injection head plate 130 to adjust its position on the base 110, thereby adjusting the relative position between the injection head plate 130 and the injection tail plate 120.

[0054] An adjustment structure 140 is disposed at the second mounting position 112 and configured to cooperate with the injection head plate 130 to adjust the position of the injection head plate 130 on the base 110 along the second direction y. The adjustment structure 140 can directly act on the injection head plate 130, driving the injection head plate 130 to move, thereby adjusting the position of the injection head plate 130 on the base 110, and further adjusting the relative position between the injection head plate 130 and the injection tail plate 120 so that their relative position meets the assembly requirements. The adjustment structure 140 can be manually driven or automatically driven by a drive component (such as a motor).

[0055] Regarding the first direction x and the second direction y, in detail, the first direction x is the direction in which the axial direction of the injection tail plate 120 (or injection head plate 130) is located, and the second direction y is perpendicular to the first direction x. Thus, when the adjustment structure 140 drives the injection head plate 130 to move along the second direction y, it adjusts the relative axial position of the injection tail plate 120 and the injection head plate 130, so that the coaxiality between the injection head plate 130 and the injection tail plate 120 meets the set threshold, ensuring that the assembly of the injection tail plate 120 and the injection head plate 130 meets the coaxial requirements. Furthermore, since the second direction y is perpendicular to the first direction x, it reduces the risk of affecting the relative distance between the injection head plate 130 and the injection tail plate 120 in the first direction x when the injection head plate 130 moves along the second direction y, resulting in higher assembly accuracy of the injection head plate 130.

[0056] Of course, due to processing technology, assembly errors and other reasons, it is difficult to guarantee an absolute perpendicular relationship between the second direction y and the first direction x. Therefore, the second direction y and the first direction x can also have a certain deviation angle relative to 90 degrees. For example, the included angle between the second direction y and the first direction x is 85 degrees to 95 degrees. However, as long as the second direction y is not parallel to the first direction x, the positional relationship between the injection head plate 130 and the injection tail plate 120 in the first direction x can be adjusted when the adjustment structure 140 adjusts the injection head plate 130.

[0057] In some embodiments, such as Figure 2 and Figure 3As shown, the second mounting position 112 includes a limiting component 1121. The limiting component 1121 includes two limiting protrusions 11211 spaced apart along the second direction y. The injection head plate 130 is disposed between the two limiting protrusions 11211 and has a gap d between it and the two limiting protrusions 11211. The two limiting protrusions 11211 of the limiting component 1121 define the approximate installation position of the injection head plate 130, reducing the degree of deviation of the injection head plate 130 relative to the injection tail plate 120. Therefore, only minor adjustments are needed to adjust the injection head plate 130 into position, making adjustment faster and assembly easier. The two limiting protrusions 11211, positioned along the second direction y, have the function of limiting the injection head plate 130 from opposite sides, reducing the possibility of the injection head plate 130 being misaligned.

[0058] The adjustment structure 140 includes an adjustment rod 141. At least one limiting protrusion 11211 in the limiting assembly 1121 has the adjustment rod 141 inserted through it. The adjustment rod 141 is configured to contact or abut against the injection head plate 130 and to extend or retract along the limiting protrusion 11211. The adjustment rod 141 has a simple structure, low cost, and is convenient for operators to use.

[0059] It should be noted that the two limiting protrusions 11211 of the limiting component 1121 may not be set along the second direction y, but may be designed to be located on both sides of the injection head plate, which can also achieve adjustment.

[0060] Furthermore, the two limiting protrusions 11211 in the limiting component 1121 are respectively provided with adjusting rods 141, so that the operator can adjust the injection head plate 130 from both sides, making the adjustment more convenient and precise.

[0061] In one specific embodiment, the limiting protrusion 11211 is provided with a threaded hole, and the adjusting rod 141 is provided with a threaded structure. The threaded structure is threadedly connected to the threaded hole. The operator can adjust the position of the injection head plate 130 by controlling the adjusting rod 141 to rotate in or out, so as to achieve stepless adjustment and higher adjustment accuracy.

[0062] Optionally, the base 110 is provided with a first mounting groove 113, and the limiting protrusion 11211 is detachably disposed in the first mounting groove 113. In this way, during the assembly process, the limiting protrusion 11211 can be removed from the first mounting groove 113 first, so that the base 110 remains relatively flat, avoiding the limiting protrusion 11211 from obstructing the installation of the injection head plate 130. After the injection head plate 130 is roughly in place, the limiting protrusion 11211 is then assembled into the first mounting groove 113. This operation makes the assembly of the injection head plate 130 more convenient.

[0063] In some embodiments, the second mounting position 112 includes two or more limiting components 1121, which are spaced apart along a first direction x. For example, the second mounting position 112 includes two limiting components 1121, which are spaced apart along the first direction x. This allows for adjustment at different positions on the injection head plate 130, further improving the accuracy of the adjustment, improving the positional accuracy of the injection head plate 130, and thus improving the positional accuracy between the injection head plate 130 and the injection tail plate 120.

[0064] Of course, the second mounting position 112 can also be designed to include three, four or more limiting components 1121 as needed.

[0065] In some embodiments, such as Figure 4 As shown, the injection head plate 130 includes a bracket 131, which is disposed between and opposite to the two limiting protrusions 11211 of the limiting assembly 1121. The bracket 131 is configured to contact or abut against the adjusting rod 141. This ensures that the adjusting rod 141 can act on the injection head plate 130, resulting in more even force distribution, and also increases the strength of the bracket 131, reducing the risk of deformation under stress.

[0066] It is worth noting that the adjusting rod 141 is only one specific implementation of the adjusting structure 140, and it is not the only one. In other embodiments, the adjusting structure 140 can be designed with other structural forms, as long as it can achieve the adjustment of the position of the injection head plate 130 in the second direction y. For example, the adjusting structure 140 can also be designed as a shim, which is detachably disposed between the second mounting position 112 and the injection head plate 130. By adjusting the number of shims between the second mounting position 112 and the injection head plate 130, the position of the injection head plate 130 on the base 110 can be adjusted, thereby adjusting the relative position between the injection head plate 130 and the injection tail plate.

[0067] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, a guide structure is provided on the second mounting position 112. The guide structure is connected to the injection head plate 130 and is adapted to guide the movement of the injection head plate 130 in the second direction y. Through the guidance of the guide structure, the positional accuracy of the injection head plate 130 in the second direction y is further improved, and the skewness of the injection head plate 130 is avoided.

[0068] Furthermore, the guiding structure includes one of a guide block 1122 and a guide groove 132. The injection head plate 130 is provided with the other of the guide block 1122 and the guide groove 132. The guide groove 132 extends along the second direction y. The guide block 1122 extends into the guide groove 132 and can move along the guide groove 132. The guide block 1122 and the guide groove 132 have a simple structure, are easy to manufacture, and provide more precise guidance.

[0069] Furthermore, the injection head plate 130 is provided with a guide groove 132. In further conjunction with the aforementioned embodiment, the bracket 131 of the injection head plate 130 is provided with a guide groove 132.

[0070] The base 110 is provided with a second mounting groove, and the guide block 1122 is detachably installed in the second mounting groove. This makes processing and installation more convenient.

[0071] In some embodiments, such as Figure 7 and Figure 8 As shown, the injection tail plate 120 is provided with a first injection structure mounting position 121 and a connecting structure 122.

[0072] The injection head plate 130 is provided with a second injection structure mounting position 133 and a drive structure mounting position 134. The adjustment structure 140 cooperates with the injection head plate 130 to adjust the position of the injection head plate 130 in the second direction y, so that the first injection structure and the second injection structure, as well as the connecting structure 122 and the drive structure mounting position 134, are arranged along the first direction x.

[0073] The first mounting position 111 is provided with a slide rail 1111, and the injection tail plate 120 is provided with a sliding part 123, which is slidably connected to the slide rail 1111.

[0074] The injection mechanism 100 also includes a drive structure 150, which is mounted on the drive structure mounting position 134 and has a connecting rod 151 connected to the connecting structure 122. The drive structure 150 can drive the injection tail plate 120 to slide along the slide rail 1111 via the connecting rod 151. For example, the drive structure 150 includes a hydraulic cylinder, and the connecting rod 151 of the drive structure 150 is the piston rod of the hydraulic cylinder.

[0075] In this way, by adjusting the position of the injection head plate 130 through the adjustment structure 140, the relative position between the injection head plate 130 and the injection tail plate is adjusted so that the two meet the coaxiality requirements. The drive structure 150 is installed on the injection head plate 130 and connected to the injection tail plate 120. The installation of the drive structure 150 and the injection structure also meets the assembly requirements, avoiding the risk of damage to the drive structure 150 and the injection structure during operation.

[0076] To illustrate further, the injection mechanism 100 includes two or more drive structures 150. Taking two as an example, the injection tail plate 120 has two connecting structures 122 on both sides of the first injection structure mounting position 121, and the injection head plate 130 has two drive structure mounting positions 134 on both sides of the second injection structure mounting position 133. The two drive structures 150 are connected to their respective connecting structures 122 and drive structure mounting positions 134. This improved assembly precision of the drive structures 150 further balances the force on the two drive structures 150, further preventing damage to the drive structures 150.

[0077] The present invention also provides an injection molding machine, comprising: an injection mechanism 100 and an injection structure according to any of the foregoing embodiments, wherein the injection structure is disposed on the injection head plate 130 and the injection tail plate 120 of the injection mechanism 100. More specifically, the injection structure is disposed on a first injection structure mounting position 121 of the injection tail plate 120 and a second injection structure mounting position 133 of the injection head plate 130.

[0078] A specific embodiment

[0079] like Figures 1 to 8 As shown, this embodiment proposes a glue injection mechanism 100, including a base 110, a glue injection tail plate 120, a glue injection head plate 130, and an adjustment structure 140.

[0080] The injection head plate 130 is equipped with two injection cylinders, which are identical in size and symmetrical to each other. The injection head plate 130 is fixed to the base 110 by screws. The base 110 is equipped with a linear slide rail 1111. The injection tail plate 120 is provided with a sliding part 123 and is slidably connected to the linear slide rail 1111 through the sliding part 123, allowing the injection tail plate 120 to move on the base 110.

[0081] The injection tail plate 120 and the piston rod of the injection cylinder are connected by a nut, and the piston rod and piston of the injection cylinder are connected by a thread. The two injection cylinders can move synchronously, pushing the injection tail plate 120 to move in the first direction x. During this process, it is necessary to ensure that the two injection cylinders are balanced by force and to ensure the coaxiality of the injection head plate 130 and the injection tail plate 120 in the second direction y.

[0082] In this embodiment, a second mounting groove is provided on each side of the base 110 in the second direction y. The dimensions of the second mounting groove are closely matched with the guide block 1122. For example, the guide block 1122 is a flat key. At the same time, a guide groove 132 is also provided on each side of the injection head plate 130 in the second direction y. The guide groove 132 is slightly longer than the guide block 1122 to ensure that the injection head plate 130 has a suitable adjustment space in the second direction y.

[0083] Two first mounting grooves 113 are provided on each side of the base 110 in the second direction y. The thickness of the limiting protrusion 11211 is the same as that of the first mounting groove 113. The limiting protrusion 11211 can be smoothly inserted into the first mounting groove 113. The limiting protrusion 11211 is provided with threaded holes. After the adjusting screw is screwed into the threaded holes on the limiting protrusion 11211, it presses against the brackets 131 on both sides of the injection head plate 130, thereby pushing the injection head plate 130 to move in the second direction y on both sides of the injection head plate 130. The adjustment ensures the coaxiality requirement of the injection head plate 130 and the injection tail plate 120 in the first direction x.

[0084] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
