Injection molds are the most commonly used molding molds in the production of thermoplastic plastic products. The corresponding processing equipment for plastic injection molds is plastic injection molding machines. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine, and then pushed by the screw or plunger of the injection machine, it enters the mold cavity through the injection machine nozzle and the mold pouring port. The plastic is cooled and hardened, and the product is demolded to obtain the product.
[0003] When the mold is placed on the injection molding machine, it is necessary to ensure that the gate of the mold completely overlaps with the position of the injection molding machine nozzle. Then the mold needs to be positioned. A concentric ring-shaped gate seat is configured in the gate. There is a positioning ring protruding on the gate seat. This positioning ring is the same size as the front template hole of the injection molding machine. After putting this positioning ring in, it can ensure that the gate position of the mold is consistent with the nozzle position.
[0004] In order to be able to snap into the nozzle position of the injection molding machine, the positioning ring of a common injection mold usually protrudes from the mold in the middle. During transportation, the positioning ring may collide with external objects and cause damage. Utility Model Content

[0038] The following is combined with Figure 1-8 This application is described in further detail.
[0039] The embodiment of the present application discloses an anti-collision injection mold positioning structure. Example
[0040] Reference Figure 1 The anti-collision injection mold positioning structure includes a base plate 1 and a gate seat 2 detachably mounted on the base plate 1 , a positioning ring 3 is integrally formed on the gate seat, and the diameter length of the positioning ring 3 is smaller than the diameter length of the gate seat 2 .
[0041] Reference Figure 2 and Figure 3 A gate 11 is provided on the bottom plate 1, and a placement groove 12 is provided in the bottom plate 1. The placement groove 12 is located on one side of the gate 11 and is connected to the gate 11. The diameter length of the placement groove 12 is smaller than the diameter length of the gate 11. When transporting the injection mold, the gate seat 2 is first removed from the gate 11, and then the gate seat 2 is turned over so that the positioning ring 3 is embedded in the placement groove 12, and then the gate seat 2 and the gate 11 are detachably installed together.
[0042] Reference Figure 2 and Figure 4 A first threaded hole 21 is provided on the gate seat 2, and a plurality of first threaded holes 21 are arranged at intervals along the circumferential direction of the gate seat 2. A screw groove 211 is formed at one end of each first threaded hole 21 for the screw head to be embedded in. The screw grooves 211 at the ends of two adjacent first threaded holes 21 are respectively located on opposite sides of the gate seat 2. A first thread groove 13 is provided in the base plate 1, and the first thread groove 13 is coaxially arranged with the first threaded hole 21 and corresponds one to one. When in use, the gate seat 2 is installed in the gate 11 by threading the screw in the first threaded hole 21 and the first thread groove 13 at the same time. The setting of the screw groove 211 can prevent the screw head of the screw from being exposed to the outside, and the different positions of the screw groove 211 can cooperate with the flip installation of the gate seat 2.
[0043] The implementation principle of the anti-collision injection mold positioning structure of Example 1 of the present application is as follows: when pouring with an injection molding machine, the connection between the gate seat 2 and the gate 11 is achieved through the threaded connection between the screw and the first threaded hole 21 and the first threaded groove 13, and the positioning ring 3 protrudes from the surface of the base plate 1; when the injection mold needs to be transported, the gate seat 2 is removed from the gate 11, and the gate seat 2 is turned over so that the positioning ring 3 is embedded in the placement groove 12 and the gate seat 2 is embedded in the gate 11, and then the screw is threadedly connected in the first threaded hole 21 and the first threaded groove 13. Through an anti-collision injection mold positioning structure, a detachable threaded connection is set between the gate seat 2 and the gate 11, so that the positioning ring 3 can be turned over during transportation to enter the placement groove 12, thereby protecting the positioning ring 3 to prevent it from colliding with the outside world during transportation and causing damage. Example
[0044] The difference between Example 2 and Example 1 is that, referring to Figure 5 and Figure 6 , the connection mode between the gate seat 2 and the base plate 1 is different. Two opposite rotating rods 22 are fixedly connected horizontally on the side wall of the gate seat 2, and two opposite rotating grooves 14 are arranged on the base plate 1 and communicated with the gate 11. The two rotating rods 22 are respectively connected to the two rotating grooves 14 in rotation.
[0045] When in use, the length and height of the placement groove 12 are just enough for the gate seat 2 to be turned over. The positioning ring 3 can be turned over by rotating the gate seat 2 to enter the placement groove 12 below.
[0046] Reference Figure 6 Two second thread grooves 15 are arranged on the bottom plate 1 at intervals. The two second thread grooves 15 are respectively perpendicular to the two rotation grooves 14 and cross-connected with the rotation grooves 14. A second threaded hole 221 is arranged on each rotation rod 22. When in use, when the positioning ring 3 is parallel to the bottom plate 1, the second threaded hole 221 is just vertically connected to the second thread groove 15. The positions of the gate seat 2 and the positioning ring 3 can be fixed by threading the same screw rod into the second threaded hole 221 and the second thread groove 15 at the same time.
[0047] The implementation principle of the anti-collision injection mold positioning structure of Example 2 of the present application is as follows: when pouring with the injection molding machine, the gate seat 2 is flipped so that the positioning ring 3 protrudes from the surface of the base plate 1, and the gate seat 2 and the positioning ring 3 are fixed on the base plate 1 through the threaded connection between the screw and the second threaded hole 221 and the second threaded groove 15; when the injection mold needs to be transported, the screw is removed from the second threaded hole 221 and the second threaded groove 15, and then the gate seat 2 is flipped so that the positioning ring 3 enters the placement groove 12, and the screw is again threadedly connected to the second threaded hole 221 and the second threaded groove 15 to fix the gate seat 2 and the positioning ring 3 on the base plate 1. Through an anti-collision injection mold positioning structure, the gate seat 2 realizes a rotational connection with the gate 11 through the rotating rod 22, and the positioning ring 3 can be flipped during transportation to enter the placement groove 12, thereby protecting the positioning ring 3 to prevent it from colliding with the outside world during transportation and causing damage. Example
[0048] The difference between Example 3 and Example 1 is that, referring to Figure 7 and Figure 8 , the connection mode between the gate seat 2 and the base plate 1 is different. When in use, the gate seat 2 no longer needs to be turned over, and the positioning ring 3 can be brought into the gate 11 by sliding between the gate 11 and the placement groove 12.
[0049] Reference Figure 8 Two arc blocks 4 are slidably connected in the placement groove 12 and are horizontally opposite to each other. The two arc blocks 4 are respectively provided with third thread grooves 41. When in use, the gate seat 2 is rotated so that the third thread groove 41 is vertically connected with the first threaded hole 21. The gate seat 2 is installed in the gate 11 by rotating the screw rod simultaneously to connect the screw rod in the first threaded hole 21 and the third thread groove 41. At this time, the positioning ring 3 is exposed to the outside to be poured by the injection molding machine.
[0050] Two arc grooves 121 facing each other horizontally are provided in the bottom plate 1. The two arc grooves 121 are connected to the placement groove 12 and are provided for two arc blocks 4 to be embedded. A limiting block 42 is fixed to the top of each arc block 4. A limiting groove 122 is provided in the bottom plate 1 for the limiting block 42 to move. The limiting groove 122 is connected to the arc groove 121. When in use, when the limiting block 42 abuts against the inner wall of the limiting groove 122 away from the placement groove 12, the arc block 4 just completely enters the arc groove 121. At this time, the gate seat 2 moves downward into the placement groove 12, thereby driving the positioning ring 3 to completely enter the gate 11; when the limiting block 42 abuts against the inner wall of the limiting groove 122 facing the placement groove 12, the arc block 4 just moves to the first threaded hole 21 and vertically connects with the third threaded groove 41. At this time, the gate seat 2 is clamped in the gate 11, and the positioning ring 3 protrudes from the surface of the bottom plate 1.
[0051] In order to fix the position of the gate seat 2 entering the placement groove 12, two fourth thread grooves 123 are arranged at intervals at the bottom of the placement groove 12. When in use, after the gate seat 2 drives the positioning ring 3 to completely enter the gate 11, the bottom of the gate seat 2 will abut against the bottom inner wall of the placement groove 12, and the gate seat 2 is rotated so that the first threaded hole is vertically connected to the fourth thread groove 123, and then the same screw is threadedly connected to the first threaded hole 21 and the fourth thread groove 123 at the same time, and the gate seat 2 is fixed for transportation.
[0052] Reference Figure 8 In order to facilitate the user to pull out the arc block 4 from the arc groove 121, the two side walls of the two arc blocks 4 close to each other are respectively provided with pulling grooves 43 for people to apply force to the arc blocks 4.
[0053] The implementation principle of an anti-collision injection mold positioning structure in Example 3 of the present application is as follows: when pouring with an injection molding machine, pull the arc block 4 out of the arc groove 121, and thread the screw into the first threaded hole 21 and the third threaded groove 41. At this time, the positioning ring 3 protrudes from the surface of the base plate 1; when the injection mold needs to be transported, remove the screw from the first threaded hole 21 and the third threaded groove 41, take out the gate seat 2, and then push the two arc blocks 4 into the arc groove 121 respectively, and then insert the gate seat 2. At this time, the gate seat 2 enters the placement groove 12 and drives the positioning ring 3 to completely enter the gate 11, and then thread the screw into the first threaded hole 21 and the fourth threaded groove 123 again. Through an anti-collision injection mold positioning structure and the sliding setting of the arc block 4, the gate seat 2 can drive the positioning ring 3 to move between the gate 11 and the placement groove 12, and can drive the positioning ring 3 to enter the gate 11 during transportation, thereby protecting the positioning ring 3 to prevent it from colliding with the outside world during transportation and causing damage.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
