Instead, a cylinder and an active core pulling mechanism are required to achieve molding. Therefore, the processing and installation of the mold are more complicated and inevitably increase the production cost of the mold, which needs to be further improved. Utility Model Content

The molding module 7 includes a moving mold core 71 embedded in the rear side of the moving pressure block 1 and a fixed mold core 72 embedded in the front side of the shaping block 2 and cooperating with the moving mold core 71.
[0027] The molding module 7 also includes a composite core-pulling module 73. The composite core-pulling module 73 includes a first slider 731 movably connected to the front side of the shaping block 2 to have left and right translation function and located to the right of the fixed mold core 72; at least two first inclined rods 732 that are obliquely interspersed in the first slider 731 and arranged in parallel from top to bottom; an inner slider 733 movably interspersed in the first slider 731 to have left and right translation function; a second inclined rod 735 obliquely interspersed in the inner slider 733; a first side molding block 734 fixed on the first slider 731 facing the fixed mold core 72; and two core blocks 736 movably connected in the first side molding block 734 to each have vertical movement function and are arranged symmetrically in the upper and lower parts. The front end of each first inclined rod 732 and the front end of each second inclined rod 735 are fixed on the moving mold core 71. The sides of the two core blocks 736 facing the inner slider 733 are movably connected to the inner slider 733 to each have left and right tilting and sliding function.
[0028] On the first side forming block 734, two first forming protrusions 7341 are formed outwardly on the side facing the fixed mold core 72. A partition groove 7342 is formed between the two first forming protrusions 7341. A recessed groove 7343 is opened on the side of the first side forming block 734 facing the first slider 731.

[0031] The molding module 7 also includes a first auxiliary core-pulling module 74. The first auxiliary core-pulling module 74 includes a second slider 741 movably connected to the front side of the shaping block 2 to have left and right translation function and located to the left of the fixed mold core 72, at least two third inclined rods 742 that are obliquely interspersed in the second slider 741 and distributed in parallel from top to bottom, and a second side molding block 743 fixed on the second slider 741 facing the fixed mold core 72. The front end of each third inclined rod 742 is fixed on the moving mold core 71. Two second molding protrusions 7431 are formed on the side of the second side molding block 743 facing the fixed mold core 72 and arranged symmetrically. A third partition block 7432 is also formed between the two second molding protrusions 7431.
[0032] The molding module 7 also includes two second auxiliary core-pulling modules 75 arranged symmetrically at the top and bottom. The second auxiliary core-pulling module 75 includes a third slider 751 movably connected to the front side of the shaping block 2 to have vertical movement function and located above or below the fixed mold core 72, a fourth inclined rod 752 obliquely inserted in the third slider 751, and a third side molding block 753 fixed on the third slider 751 facing the fixed mold core 72. The front end of the fourth inclined rod 752 is fixed on the moving mold core 71. A third molding protrusion 7531 is formed on the side of the third side molding block 753 facing the fixed mold core 72. A fourth molding protrusion 7532 is formed on the left side of the end of the third molding protrusion 7531 facing the fixed mold core 72. An obliquely arranged first honeycomb molding surface 7533 is formed on the end face of the fourth molding protrusion 7532.
[0033] A main molding block 721 is formed on the end face of the fixed mold core 72 in the direction of the moving mold core 71. Two fourth molding protrusions 722 are formed on the end face of the main molding block 721 in the direction of the moving mold core 71. A second honeycomb-shaped molding surface 723 is formed on the right edge of the end of each of the two fourth molding protrusions 722. A positioning notch 724 is opened on the right end of the upper and lower outer walls of the main molding block 721.
[0034] Working principle:
[0035] The feed block 5 and the base block 4 are respectively installed on the action mechanism and the machine body of the injection molding machine. The action mechanism drives the feed block 5 to move backward, and then the flow divider block 3 drives the dynamic pressure block 1 to move backward and towards the shaping block 2 until the end faces of the two are joined together (existing technology).
[0036] At this time, the end face of the moving mold core 71 in each molding module 7 also fits into the end of the fixed mold core 72. During the movement, the moving mold core 71 will be forced to move the first slider 731 to the left by each first inclined rod 732 in the composite core pulling module 73, thereby driving the second partition block 7345 and the two first partition blocks 7344 on the first side molding block 734 to move to the right front of the main molding block 721. At the same time, the second inclined rod 735 will also force the inner slider 733 to move to the left, thereby forcing the two core blocks 736 to move vertically closer by the upper and lower inner walls of the V-groove 7331, thereby driving the two stepped grooves 7362 to move towards a cavity 7346 on the same side, until the three protrusions 7363 on each stepped groove 7362 pass through a cavity 7346 on the same side and respectively attach to the corresponding outer walls of the second partition block 7345 and the two first partition blocks 7344.
[0037] During the movement of the moving mold core 71, the second slider 741 will be forced to move to the right by each of the third inclined rods 742 in the first auxiliary core pulling module 74 until the second molding protrusion 7431 on the second side molding block 743 moves to the left front of the main molding block 721.
[0038] During the movement of the moving mold core 71, the fourth inclined rod 752 in each of the second auxiliary core-pulling modules 75 will be used to force each third slider 751 to move upward or downward toward the fixed mold core 72, until the third forming protrusions 7531 on the two third side forming blocks 753 pass through the two positioning notches 724 and move to the front of the upper and lower sides of the main forming block 721 respectively.
[0039] Subsequently, the molten material enters the moving mold core 71 and the fixed mold core 72 in each molding module 7 through the gate in the feed block 5 and the runner in the flow divider block 3, and is located between the second partition block 7345, the two first partition blocks 7344, the second molding protrusion 7431 and the two third molding protrusions 7531. After cooling, it forms the upper housing of the air conditioner outlet (existing technology).
[0040] Then, the feeding block 5 is driven forward by the action mechanism, and the dynamic pressure block 1 is driven forward and away from the shaping block 2 by the diversion block 3. This causes the moving mold core 71 in each molding module 7 to leave the fixed mold core 72. Finally, the upper shell of the air conditioner outlet is pushed forward by the ejection mechanism 6 (existing technology).
[0041] This invention can form a pin on the upper housing of the air conditioner vent with a demolding direction perpendicular to the mold parting direction in one go without adding a cylinder and a matching active core pulling mechanism, by means of a nested two-stage passive core pulling method of the composite core pulling module 73. This greatly simplifies the mold processing and installation process and effectively reduces the mold manufacturing cost.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
