[0040] It should be noted that each layer of the upper mold plate in the upper mold body 110 is provided with a through hole to accommodate the embedding of the glue injection pipe 800.

[0041] refer to Figure 2 , Figure 2 An exploded view of an inlaid mold provided in one embodiment of the utility model.

[0042] In one embodiment of the utility model, the molding shell 200 is arranged inside the molding cavity 120 to enable the product to be injection molded. The bottom of the molding shell 200 is provided with a accommodating cavity, and the side wall of the molding shell 200 is also provided with a groove, so that it can be clamped with the embedding mechanism to achieve position fixation.

[0043] It should be noted that the plastic part is molded on the outside of the molding shell 200, that is, during the injection molding process of the plastic part, the plastic part is molded on the molding shell 200, and the molding shell 200 supports the molding of the plastic part inside the plastic part, wherein the cross-sectional shape of the molding shell 200 can be rectangular, cylindrical or other irregular shapes, etc., and this embodiment does not make specific restrictions.

[0044] It can be understood that the number of molding shells 200 in this embodiment can be set according to the needs of the user. For example, two groups of molding shells 200 are set, and the number of molding shells 200 in each group is four; four molding shells 200 are set; three groups of molding shells 200 are set, and the number of molding shells 200 in each group is two, etc. This embodiment does not make specific restrictions.

[0045] refer to Figure 3 , Figure 3 A schematic diagram of an embedding mechanism provided in one embodiment of the utility model.

[0046] In one embodiment of the utility model, an embedding mechanism is arranged inside the accommodating cavity, and the embedding mechanism includes an embedding component 310 and a slider assembly. At least one trapezoidal protrusion structure 311 and a plurality of dovetail grooves 312 arranged along the oblique sides of the trapezoidal protrusion structure 311 are arranged at the top of the embedding component 310. The slider in the slider assembly is movably connected with the two oblique sides of the trapezoidal protrusion structure 311 through the dovetail grooves 312, so that the slider in the slider assembly can slide on the two oblique sides of the trapezoidal protrusion structure 311, and a limiting protrusion 323 is arranged at the tail end of the slider. The limiting protrusion 323 is clamped with the bottom of the molding shell 200 to limit the position of the molding shell 200. Specifically, the limiting protrusion 323 is clamped with the groove of the side wall of the molding shell 200, so that the molding shell 200 can change its position with the movement of the slider, thereby saving costs, effectively utilizing the mold space, simplifying the mold structure, enabling the product to be demolded smoothly and meet the technical requirements and use requirements, and improving production efficiency.

[0047] It is understandable that in this embodiment, a dovetail groove 312 is respectively provided on both sides of the trapezoidal protrusion structure 311 , and the opening end of the dovetail groove 312 is connected to the tail end of the trapezoidal protrusion structure 311 .

[0048] In one embodiment of the utility model, the inlaid mold also includes a connecting rod 500, one end of the connecting rod 500 is connected to the tail of the insert 310 to drive the insert 310 to move, and the other end is connected to an external driving mechanism to pull the insert 310, thereby realizing the movement of the insert 310, and further driving the movement of the slider in the process of pulling the insert 310 out of the molding shell 200 to realize the demolding of the plastic part.

[0049] It should be noted that the molding shell 200 is mounted on the embedding mechanism, and the insert 310 and the slider assembly in the embedding mechanism can fix the molding shell 200 at different positions. During the injection molding process of the product, the insert 310 and the slider assembly abut against each other, limiting the molding shell 200 at a fixed position to wait for the product to be injection molded into a specific shape. When the plastic part is molded, the embedding mold is opened. At this time, the connecting rod 500 pulls out the insert 310 downward. Under the action of the dovetail groove 312 and the hypotenuse of the trapezoidal protrusion structure 311, the sliders on both sides of the insert 310 move toward the position of the insert 310, so that the position of the limiting protrusion 323 changes, further changing the position of the molding shell 200, realizing the demolding of the plastic part, and making the plastic part easy to remove.

[0050] refer to Figure 4 , Figure 4 A cross-sectional view of an inlaid mold provided in one embodiment of the utility model.

[0051] In one embodiment of the utility model, the dovetail groove 312 is symmetrically arranged on the hypotenuse side of the trapezoidal protrusion structure 311, and its direction is consistent with the hypotenuse direction of the trapezoidal protrusion structure 311. The depth of the dovetail groove 312 gradually deepens from the tail end of the insert 310 toward the trapezoidal protrusion structure 311, so as to facilitate the movement of the slider in the dovetail groove 312.

[0052] In one embodiment of the utility model, the inlaid mold also includes a traction spring 330, which is abutted against the slider assembly through the second fixing member 420. The traction spring 330 is used to drive the slider in the slider assembly to move, thereby ensuring the position of the slider, so that the slider can move along the hypotenuse of the trapezoidal protrusion structure 311.

[0053] refer to Figure 5 , Figure 5 A cross-sectional view of an inlaid mold provided in another embodiment of the utility model.

[0054] In an embodiment of the present invention, the slider assembly includes a first slider 321 and a second slider 322. The first slider 321 and the second slider 322 are symmetrically arranged on both sides of the insert 310 with the trapezoidal protrusion structure 311 as the center. Figure 4Taking the example that the first slider 321 is set on the left side of the insert 310 and the second slider 322 is set on the right side of the insert 310, the first slider 321 and the second slider 322 are engaged in the insert 310 through the dovetail groove 312. After the plastic part is molded and the insert mold is opened, the connecting rod 500 pulls the insert 310 downward. Under the action of the dovetail groove 312 and the hypotenuse of the trapezoidal protrusion structure 311, the first slider 321 and the second slider 322 move toward the position of the insert 310 at the same time, so that the position of the limiting protrusion 323 changes, and the position of the molded shell 200 is further changed.

[0055] It should be noted that, in the present embodiment, a fixing protrusion 324 is further provided at the top of the slider in the slider assembly. Correspondingly, a fixing through hole is opened on the side wall of the molding shell 200. When the slider assembly and the insert 310 are abutted against the molding shell 200, the fixing protrusions 324 of the first slider 321 and the second slider 322 respectively penetrate the molding shell 200 through the fixing through hole, thereby fixing the position of the molding shell 200, preventing the molding shell 200 from moving during the injection molding process of the product, maintaining the stability of the product size, improving production efficiency, and ensuring product consistency.

[0056] In one embodiment of the utility model, the inlaid mold also includes a fixing mechanism for fixing the molding shell 200, and the fixing mechanism includes a first fixing member 410 and a second fixing member 420. The first fixing member is embedded in the top of the molding cavity 120, and the second fixing member is embedded in the top of the lower mold body 130. The second fixing member is provided with a fixing through hole, and the top of the molding shell 200 passes through the fixing through hole to abut the first fixing member, thereby fixing the molding shell 200 and improving the stability of the molding shell 200 during the processing.

[0057] It should be noted that a portion of the molding shell 200 penetrates into the molding cavity 120 through the fixing through hole and abuts against the first fixing member, and the other portion remains outside the molding cavity 120, that is, embedded in the lower mold body 130, thereby improving the demoulding efficiency of the product.

[0058] In one embodiment of the utility model, the inlaid mold also includes an opening and closing mechanism for fixing the opening and closing distance of the inlaid mold. The opening and closing mechanism penetrates the lower mold body 130 to embed into the molding cavity 120. The opening and closing mechanism includes a limiting screw 610 and a slingshot 620. The slingshot 620 is sleeved on one end of the limiting screw 610 inserted into the molding cavity 120, thereby fixing the opening and closing distance and opening and closing sequence of the mold, improving the demolding efficiency of the product, and avoiding position movement during the demolding process, thereby improving the yield rate of the product.

[0059] It should be noted that the number of opening and closing mechanisms in this embodiment is set according to the number of molded shells 200. When the number of molded shells 200 is large, the opening and closing mechanisms can be set to four, six, etc.; when the number of molded shells 200 is small, the opening and closing mechanisms can be set to one, two, etc., and this embodiment does not make specific restrictions.

[0060] In one embodiment of the utility model, the mosaic mold also includes a lifting mechanism, which includes a mounting base 710 and a lifting ring 720 arranged on the mounting base 710, the mounting base 710 is respectively connected to the upper mold body 110, the molding cavity 120 and the lower mold body 130, and the lifting ring 720 is used for an external lifting device, so that the whole set of molds or half a set of molds can be lifted, and the balance can be maintained during the mold lifting process.

[0061] It should be noted that one end of the mounting base 710 in this embodiment is connected to the upper mold body 110 and the molding cavity 120 , and the other end is connected to the lower mold body 130 , so as to maintain balance during the mold hoisting process.

[0062] In one embodiment of the utility model, the inlaid mold also includes a glue injection pipe 800, the input end of the glue injection pipe 800 is arranged on the top of the upper mold body 110, and the output end of the glue injection pipe 800 is connected to the molding cavity 120, so as to guide the glue to flow into the cavity, ensuring that the molten plastic can evenly and quickly fill the entire cavity, thereby improving the molding quality and precision of the product. The glue injection pipe 800 can reduce the pressure loss of the glue during the transportation process.

[0063] It is understandable that the cross-sectional area of ​​the glue injection pipe 800 can be rectangular, funnel-shaped, etc., and this embodiment does not impose any specific limitation.

[0064] In one embodiment of the utility model, the inlaid mold also includes a positioning device 900 for positioning the upper mold body 110, the molding cavity 120 and the lower mold body 130. The positioning device passes through the upper mold body 110, the molding cavity 120 and the lower mold body 130 in sequence to fix the positions of the upper mold body 110, the molding cavity 120 and the lower mold body 130, thereby avoiding position deviation between the upper mold body 110, the molding cavity 120 and the lower mold body 130.

[0065] It is worth noting that the positioning device includes a guide pin and a guide sleeve. The guide sleeve is arranged on the outside of the guide pin, wherein the guide pin is used to guide the closing and separation movement of the mold, ensure the precise positioning of the mold during the movement, and ensure the accuracy and consistency of product processing. The guide sleeve is used to reduce the friction between the guide pin and the upper mold body 110 and the lower mold body 130, and provide support and positioning, reduce the wear of the guide pin, thereby extending the life of the mold, and can also avoid shaking and deformation of the mold during operation, thereby improving the stability of the mold.
