[0034] In the prior art, as Figure 1 , Figure 1 The multiple buckle position product 10 is provided with multiple buckle positions 11 on the upper and lower circumferential sides, the upper side of the multiple buckle position product 10 is provided with multiple folding edge portions 12, and the side portion of the multiple buckle position product 10 is provided with a side hole 13. For injection molding of this product, the existing mold usually makes the multiple buckle position product 10 in the cavity 101 form the folding edge portion 12 and the side hole 13 through the row position piece 210 and the insert piece 212 of the row position mechanism, and makes the multiple buckle position product 10 in the cavity 101 form the buckle position 11 through the buckle portion 211 of the decoupling structure. Since the buckle position 11 is relatively large in number, a large number of decoupling structures need to be provided, which leads to a relatively complex structure of the mold and a high cost, and is not conducive to production and application.

[0035] Referring to Figure 2 , Figure 3 and Figure 4 , an injection mold for a multiple buckle position product includes a movable mold assembly 110, a fixed mold assembly 120, and a row position mechanism. The fixed mold assembly 120 is arranged on the lower side of the movable mold assembly 110 and can cooperate with the movable mold assembly 110 to define a cavity 101. The row position mechanism includes four row position pieces 210, which are respectively arranged on the front side, rear side, left side, and right side of the cavity 101. At least part of the four row position pieces 210 is provided with a buckle portion 211 for forming a buckle position 11 of an injection molded product. The four row position pieces 210 are all slidingly connected to the fixed mold assembly 120 and can move horizontally towards or away from the cavity 101, so that the buckle portion 211 on the row position piece 210 can move to the side of the cavity 101 or away from the cavity 101.

[0036] As Figure 2 , Figure 3 and Figure 4 indicated, the four row position pieces 210 are respectively arranged on the front side, rear side, left side, and right side of the cavity 101. Among them, the left and right two row position pieces 210 are both provided with a buckle portion 211 on the side close to the cavity 101. According to the needs, part of the four row position pieces 210 is provided with an insert piece 212 for forming a side hole 13 of the multiple buckle position product 10, and the four row position pieces 210 all move horizontally relative to the cavity 101. Referring to Figure 3 , Figure 4 and Figure 6, the direction of moving close to the cavity 101 is inward, the direction of moving away from the cavity 101 is outward, when in use, the movable die assembly 110 is combined with the fixed die assembly 120, the four row position pieces 210 of the row position mechanism move horizontally inward when the mold is closed, so that the buckle part 211 on the row position piece 210 can move to the side of the cavity 101; when injection molding, the row position piece 210 is used to form the folded edge part 12 of the multi-buckle position product 10 in the cavity 101, the buckle part 211 is used to form the buckle position 11 on the upper side of the multi-buckle position product 10 in the cavity 101, and the insert 212 is used to form the side hole 13 of the multi-buckle position product 10 in the cavity 101; when the movable die assembly 110 and the fixed die assembly 120 are opened, the four row position pieces 210 of the row position mechanism move horizontally and outwardly, so that the buckle part 211 on the row position piece 210 can move away from the cavity 101, thereby separating from the buckle position 11 on the upper side of the injection molded product, realizing the buckle, the row position piece 210 is separated from the folded edge part 12, and the insert 212 is separated from the side hole 13, thereby facilitating the demolding of the injection molded product in the subsequent cavity 101. The buckle part 211 for forming the buckle position 11 is arranged on the row position piece 210, part of the buckle structure is integrated on the row position mechanism, and part of the buckle position 11 on the multi-buckle position product 10 is buckled by using the row position mechanism, so that the structure of the mold is simplified, the internal structure of the mold is more compact, the volume of the mold is reduced, and the manufacturing cost is reduced.

[0037] In practical application, the specific structure of the movable die assembly 110 and the fixed die assembly 120 can be set according to actual use needs, and the specific structure of the row position mechanism will not be described in detail here, and will be described in detail below.

[0038] In some embodiments, the row position mechanism further comprises a wedge piece 220, the wedge piece 220 is provided with four and is respectively arranged corresponding to the four row position pieces 210, the wedge piece 220 is connected to the movable die assembly 110 and moves with the movable die assembly 110, and the wedge piece 220 and the corresponding row position piece 210 are matched through a wedge structure, so that the wedge piece 220 can drive the row position piece 210 to move horizontally when moving longitudinally.

[0039] It can be understood that, as Figure 4 , Figure 5 and Figure 6As shown, the four inclined wedge members 220 are connected to the movable die assembly 110 and move up and down with the movable die assembly 110, and the four inclined wedge members 220 correspond to the four row position members 210 one by one. Each inclined wedge member 220 is matched with the corresponding row position member 210 through an inclined wedge structure. When the mold is opened and closed, the movable die assembly 110 moves up and down relative to the fixed die assembly 120, thereby driving the inclined wedge member 220 to move up and down. When the inclined wedge member 220 moves upward, it can drive the corresponding row position member 210 to move horizontally outward. When the inclined wedge member 220 moves downward, it can drive the corresponding row position member 210 to move horizontally inward, so as to realize the positioning and locking of the row position member 210 when the mold is closed, and drive the row position member 210 to move away from the injection molding product when the mold is opened, which is convenient to use. In actual application, in addition to the inclined wedge member 220, the row position member 210 can also be directly driven to move by a driver. The specific configuration can be set according to actual needs.

[0040] In some embodiments, the row position mechanism further comprises a stop member 230 movably connected to the row position member 210 and capable of contacting the injection molding product in the cavity 101. When the row position member 210 moves away from the cavity 101, the stop member 230 can limit the injection molding product in the cavity 101 from moving with the row position member 210.

[0041] It can be understood that, as Figure 6 shown, the stop member 230 is movably inserted into the row position member 210 and can move horizontally. It can move horizontally inward to the side of the cavity 101, or move horizontally outward away from the cavity 101. In the closed mold state, the position of the stop member 230 is as Figure 6 shown. At this time, the end of the stop member 230 is at the side of the cavity 101. After injection molding, the injection molding product in the cavity 101 contacts the stop member 230. When the mold is opened, the inclined wedge moves upward and drives the row position member 210 to move horizontally outward. At this time, by contacting the injection molding product in the cavity 101 through the stop member 230, the injection molding product in the cavity 101 is limited from moving with the row position member 210, thereby reducing the possibility of deformation of the injection molding product caused by the row position member 210, which is convenient to use. In actual application, the specific structure of the stop member 230 can be set according to actual needs.

[0042] In some embodiments, the row position mechanism further comprises a trigger 231 arranged on the side of the stopper 230 away from the cavity 101 and matched with the stopper 230, the inclined wedge 220 is correspondingly provided with a clearance recess 221, the clearance recess 221 is provided with a pushing surface 222 extending in the longitudinal direction, the trigger 231 can be in contact with the pushing surface 222 in the clearance recess 221, the trigger 231 can move out of or into the clearance recess 221 along with the movement of the inclined wedge 220, when the row position member 210 moves away from the cavity 101, the pushing surface 222 can make the stopper 230 keep in contact with the injection molded product in the cavity 101 through the trigger 231.

[0043] It can be understood that, as shown in Figure 3 and Figure 6 , the trigger 231 is arranged on the side of the stopper 230 away from the cavity 101 and fixedly matched with the stopper 230, the inclined wedge 220 is correspondingly provided with a clearance recess 221, the clearance recess 221 is provided with a pushing surface 222 extending in the longitudinal direction. Referring to Figure 3 and Figure 6 , in the mold closing state, the end of the trigger 231 is located in the clearance recess 221 and in contact with the pushing surface 222 in the clearance recess 221, when the mold is opened, the inclined wedge 220 moves upward and drives the row position member 210 to move horizontally outward, at this time, the pushing surface 222 extending in the longitudinal direction pushes the trigger 231 in the process of moving on the inclined wedge 220, so as to limit the movement of the trigger 231 and the stopper 230 along with the row position member 210, so that the stopper 230 can keep in contact with the injection molded product in the cavity 101, and the possibility of deformation of the injection molded product caused by the pulling of the row position member 210 is reduced; after the inclined wedge 220 moves a preset distance, the end of the trigger 231 moves out of the clearance recess 221 from the lower side of the clearance recess 221, at this time, the row position member 210 has been separated from the injection molded product, the inclined wedge 220 continues to move upward, and due to the lack of pushing of the pushing surface 222, the trigger 231 and the stopper 230 will move horizontally outward along with the stopper 230, so that the stopper 230 is separated from the injection molded product, thereby realizing the delayed action of the row position member 210 and the stopper 230, which is beneficial to the subsequent demolding of the injection molded product.

[0044] In actual application, in addition to realizing the delayed action of the row position member 210 and the stopper 230 through the above structure, the stopper 230 can also be connected to a driver to control the action timing of the stopper 230, which can be set according to actual use needs.

[0045] In some embodiments, the row position mechanism further comprises an elastic member 232 acting on the stopper 230, which can make the stopper 230 have a tendency to move away from the cavity 101 and can make the trigger 231 in contact with the pushing surface 222.

[0046] As shown in Figure 3 and Figure 6 , by setting the elastic member 232, the elastic member 232 is used to make the stopper 230 have a tendency to move away from the cavity 101, so as to facilitate the reset of the stopper during the mold closing, and under the action of the elastic member 232, the end of the trigger 231 can be kept in contact with the abutting surface 222 when it is in the empty position 221, which is convenient to use. In actual application, in addition to setting the elastic member 232, a magnetic structure can also be set, which uses magnetic attraction or magnetic repulsion to make the stopper 230 have a tendency to move away from the cavity 101 and make the trigger 231 contact with the abutting surface 222. The specific setting can be made according to the actual use needs.

[0047] In some embodiments, the elastic member 232 is a spring and is sleeved on the stopper 230, and the two ends of the elastic member 232 act on the stopper 230 and the row position member 210 respectively.

[0048] As shown in Figure 3 and Figure 6 , the elastic member 232 is a spring, the stopper 230 is a long strip structure, the end of which is provided with a flange, the elastic member 232 is sleeved on the stopper 230 and the two ends thereof act on the stopper 230 and the row position member 210 respectively, so as to realize the application of force to the stopper 230, which is simple in structure and convenient to assemble and use. In actual application, in addition to the spring, the elastic member 232 can also be a sleeve or an elastic sheet made of elastic material, and the specific setting can be made according to the actual use needs.

[0049] In some embodiments, the injection mold of the multi-docking position product further comprises a inclined ejector mechanism, which is arranged on the lower side of the cavity 101 and is used to push the injection product in the cavity 101 upward to move away from the cavity 101.

[0050] As shown in Figures 3 to 7 , by setting the inclined ejector mechanism, after the movable mold assembly 110 and the fixed mold assembly 120 are opened, the injection product in the cavity 101 can be pushed upward by the inclined ejector mechanism to move away from the cavity 101, so as to realize the demolding of the injection product, which is simple in structure and convenient to use. In actual application, the specific structure of the inclined ejector mechanism can be set according to the actual use needs, which will not be described in detail here, and will be described in detail below.

[0051] In some embodiments, the inclined ejector mechanism includes a pusher 310 and an inclined ejector 320. The pusher 310 is movably connected to the fixed mold assembly 120. The lower part of the inclined ejector 320 is slidably connected to the upper side of the pusher 310 and can move horizontally relative to the pusher 310. The fixed mold assembly 120 is provided with an insertion hole 121 that mates with the inclined ejector 320. The side of the insertion hole 121 communicates with the cavity 101. The upper part of the inclined ejector 320 is slidably inserted into the insertion hole 121 and the sliding direction is inclined relative to the longitudinal direction. The inclined ejector 320 is provided with a latch 211 corresponding to the cavity 101. The pusher 310 can push the inclined ejector 320 to move upward. When the inclined ejector 320 moves upward, it can move horizontally away from the cavity 101 through the sliding engagement with the insertion hole 121, so that the latch 211 on the inclined ejector 320 can move to separate from the injection molded product in the cavity 101.

[0052] Understandably, such as Figures 3 to 7 As shown, four pushers 310, four angled pushers 320, and four insertion holes 121 are provided. The four angled pushers 320 are distributed to correspond to the four snap positions 11 on the lower periphery of the multi-snap product 10. Each angled pusher 320 has a snap part 211. The insertion hole 121 is vertically connected, and its upper and side parts are connected to the cavity 101. The angled pusher 320 is inserted into the insertion hole 121, and its snap part 211 is located on the side of the cavity 101 to form the snap positions 11 on the lower periphery of the multi-snap product 10. The angled pusher 320 slides with the insertion hole 121, and the sliding direction is inclined relative to the longitudinal direction. The lower part of the angled pusher 320 is slidably connected to the upper side of the pusher 310 and can move horizontally relative to the pusher 310. In use, refer to... Figure 7 In the mold-closed state, the snap-fit ​​portion 211 of the inclined ejector 320 is located on the side of the cavity 101, so that the lower periphery of the multi-snap product 10 in the cavity 101 forms snap-fit ​​11. During demolding, the ejector 310 pushes the inclined ejector 320 upward. Since the inclined ejector 320 slides with the insertion hole 121 and the sliding direction is inclined relative to the longitudinal direction, the inclined ejector 320 not only pushes the multi-snap product 10 in the cavity 101 upward for demolding during the upward movement, but also generates a horizontal force relative to the ejector 310. The horizontal movement of the ejector 320 causes it to move outward away from the cavity 101, thereby separating the latch 211 on it from the multi-latch product 10 in the cavity 101. This disengages the latch 11 on the lower periphery of the multi-latch product 10. By integrating part of the disengagement structure onto the ejector mechanism, the ejector mechanism is used to disengage part of the latch 11 on the multi-latch product 10. This simplifies the mold structure, makes the internal structure of the mold more compact, and facilitates reducing the size of the mold and manufacturing costs.

[0053] In actual application, the inclined top piece 320 can not be provided with the buckle part 211, and the buckle part 211 on the inclined top piece 320 can be provided on the row piece 210 or the insert piece 212, and the specific setting can be determined according to actual use requirements.

[0055] It can be understood that, as shown in Figure 5 and Figure 7 , the first sliding groove 122 is provided on the wall of the insert hole 121 away from the cavity 101, the first sliding groove 122 extends in a direction inclined to the longitudinal direction and is in sliding fit with the side of the inclined top piece 320, by setting the first sliding groove 122 in a dovetail groove structure, the moving direction of the inclined top piece 320 can be better limited, and the possibility of movement deviation can be reduced. In actual application, in addition to the above structure, a guide rail can also be provided on the wall of the insert hole 121, and a guide groove matched with the guide rail is provided on the inclined top piece 320, so as to realize the sliding fit between the two, and the specific change can be determined according to actual use requirements.
