Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, and in particular to a feeding fixture and feeding equipment. Background Technology
[0002] Insert injection molding is a molding method in which inserts are pre-fixed in appropriate positions within a mold, and then liquid material is injected into the molding cavity to form a molded product that bonds and solidifies with the insert. Proper installation of the insert is crucial to ensure the desired injection molding effect.
[0003] In existing technologies, inserts are installed manually one by one, which makes it difficult to control their placement. Often, the only way to ensure that an insert is in place is to press it down to sense its position, which increases the difficulty of the operation. Utility Model Content
[0004] In order to solve the technical problem of the difficulty in installing inserts in the above-mentioned insert injection molding, this utility model provides a feeding fixture and feeding equipment that can push inserts into place in batches.
[0005] A first aspect of this utility model provides a feeding fixture, including a first feeding plate, a second feeding plate, an elastic element, a pre-installation plate, and a push rod. The first feeding plate and the second feeding plate are arranged at intervals relative to each other. The elastic element is sandwiched between the first feeding plate and the second feeding plate and undergoes compression deformation in response to pressure from the first feeding plate. The pre-installation plate is fixed to the side of the second feeding plate away from the first feeding plate. Multiple mounting positions are provided corresponding to the mold cavity for mounting inserts. The push rod is fixed to the first feeding plate, penetrates the second feeding plate, and is inserted into the mounting position in response to pressure from the first feeding plate, pushing the insert from the mounting position into the mold cavity.
[0006] In some embodiments, the elastic element includes a spring and a guide post. The spring is sleeved on the guide post and sandwiched between the first feed plate and the second feed plate. The guide post includes a first fixed end and a column body connected together. The first fixed end is fixed to the first feed plate, and the column body penetrates through the second feed plate.
[0007] In some embodiments, the guide post further includes a limiting end, which is disposed at opposite ends of the post body, and the limiting end intermittently abuts against the side surface of the second feeding plate away from the first feeding plate as the spring extends and retracts.
[0008] In some embodiments, the first feeding plate includes a first plate and a second plate that are stacked and fixed together. The push rod includes a second fixed end, a first rod, and a pushing end connected in sequence. The diameter of the second fixed end is larger than that of the first rod. The second plate is provided with a fixing groove corresponding to the second fixed end. The first rod passes through the fixing groove from the pushing end. The fixing groove cooperates with the first plate to fix and accommodate the second fixed end.
[0009] In some embodiments, a limiting rod is included, the limiting rod comprising a third fixed end and a second rod body connected together, the third fixed end being fixed to the first feeding plate, and the second rod body initially maintaining a preset distance from the second feeding plate.
[0010] In some embodiments, the mounting position is provided with a groove, two mounting posts and a through hole. The two mounting posts are located on the bottom surface of the groove, and the through hole is located between the two mounting posts.

[0028] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a three-dimensional assembly structure diagram of a feeding fixture provided in an embodiment of the present utility model. Figure 2 for Figure 1The diagram shows the assembly of the feeding fixture and the mold. This embodiment of the invention provides a feeding fixture 10 for feeding materials into a mold, specifically for installing an insert 30 into the mold 20. The feeding fixture 10 includes a first feeding plate 11, a second feeding plate 13, an elastic element 15, a push rod 17, and a pre-installation plate 19. The first feeding plate 11 and the second feeding plate 13 are spaced apart from each other, and the elastic element 15 is sandwiched between the first feeding plate 11 and the second feeding plate 13. The pre-installation plate 19 is fixed to the side of the second feeding plate 13 away from the first feeding plate 11 and is used to install the insert 30. The push rod 17 is fixed to the first feeding plate 11 and passes through a first through hole 131 in the second feeding plate 13, used to push the insert 30 into the cavity 21 of the mold 20.
[0029] Please see Figure 3 ,for Figure 1 The diagram shows an exploded view of the feeding fixture. The elastic element 15 includes a spring 151 and a guide post 153. The spring 151 is sleeved on the guide post 153 and sandwiched between the first feeding plate 11 and the second feeding plate 13. The guide post 153 includes a first fixed end 1531, a column body 1532, and a limiting end 1533 connected in sequence. That is, the limiting end 1533 and the first fixed end 1531 are respectively located at opposite ends of the column body 1532. The first fixed end 1531 is fixed to the first feeding plate 11, and the column body 1532 passes through the second through hole 132 of the second feeding plate 13. When the spring 151 compresses in response to the pressure of the first feed plate 11, the distance between the first feed plate 11 and the second feed plate 13 changes accordingly. The limiting end 1533 intermittently abuts against the side surface of the second feed plate 13 away from the first feed plate 11 to restrict the guide post 153 from coming off the second feed plate 13.
[0030] The push rod 17 includes a second fixed end 171, a first rod body 173, and a pushing end 175 connected in sequence. The diameter of the second fixed end 171 is larger than that of the first rod body 173. The first feeding plate 11 includes a first plate body 111 and a second plate body 112 stacked and fixed. The second plate body 112 is provided with a fixing groove 1121 corresponding to the second fixed end 171. The first rod body 173 passes through the fixing groove 1121 from the pushing end 175. The fixing groove 1121 cooperates with the first plate body 111 to fix and receive the second fixed end 171, thereby fixing the push rod 17 to the first feeding plate 11. When the distance between the first feeding plate 11 and the second feeding plate 13 decreases, the first rod body 173 extends out of the second feeding plate 13 and into the pre-assembly plate 19.
[0031] In a further embodiment, the feeding fixture 10 may also include a limiting rod 18, the limiting rod 18 including a third fixed end 181 and a second rod body 182 connected in sequence, the third fixed end 181 being fixed to the first feeding plate 11, the length of the second rod body 182 being less than that of the first rod body 173, and the second rod body 182 and the second feeding plate 13 initially maintaining a preset distance when the first feeding plate 11 is not under pressure.
[0032] Understandably, the column 1532 guides the movement of the first feed plate 11, and the limiting end 1533 restricts the first feed plate 11 from moving away from the second feed plate 13 to its final travel point. The second rod 182 restricts the first feed plate 11 from moving towards the second feed plate 13 to its final travel point.
[0033] Please see Figure 4 ,for Figure 3 The diagram shows a three-dimensional assembly structure of the pre-assembly plate and the second feeding plate. The pre-assembly plate 19 has an mounting position 191 corresponding to the cavity 21 of the mold 20, and the insert 30 is mounted on the mounting position 191. The mounting position 191 has a groove 1911, two mounting posts 1913, and a third through hole 1915. The two mounting posts 1913 are located on the bottom surface of the groove 1911, and the third through hole 1915 is located between the two mounting posts 1913.
[0034] The insert 30 is sleeved and installed on the two mounting posts 1913. The third through hole 1915 is coaxially arranged with the first through hole 131 so that the pushing end 175 of the push rod 17 pushes the insert 30 from the two mounting posts 1913 into the mold cavity 21 of the mold 20 along the third through hole 1915.
[0035] It is understood that there can be multiple mounting positions 191 and push rods 17, and they correspond one-to-one. One mounting position 191 can mount one insert 30, and multiple inserts 30 can be batch-loaded.
[0036] It should be noted that when using the feeding fixture 10, it is placed on the mold 20, and the mold cavity 21 corresponds one-to-one with the mounting position 191. Handles 133 are also provided on both sides of the second feeding plate 13 to facilitate loading and unloading the feeding fixture 10.
[0037] In a further embodiment, the pre-mounted plate 19 further includes a positioning hole 193, and the mold 20 is provided with a positioning post 22 corresponding to the positioning hole 193. It can be understood that, through the cooperation of the positioning hole 193 and the positioning post 22, when the feeding fixture 10 is placed on the mold 20, the mold cavity 21 corresponds one-to-one with the mounting position 191, without the need for manual alignment.
[0038] Please see Figure 5 ,for Figure 3 The diagram shows an exploded perspective view of the mold. The mold 20 includes a base mold 23, a first mold core 24, and a second mold core 25. The first mold core 24 is mounted on the base mold 23, and the two are interconnected. The second mold core 25 penetrates the base mold 23 through the interconnection and is inserted into the first mold core 24. The first mold core 24 and the second mold core 25 together form the mold cavity 21. The number of second mold cores 25 corresponds one-to-one with the number of mold cavities 21.
[0039] Please see Figure 6 ,for Figure 2 The diagram shows a cross-sectional view and enlarged view of the loading fixture and mold in their assembled state. When using the loading fixture 10, it is placed with the pre-mounted plate 19 facing upwards, and the insert 30 is installed in the mounting position 191 of the pre-mounted plate 19. After installation, the loading fixture 10 is flipped over, and the loading fixture 10 is installed on the mold 20 by inserting the positioning pin 22 of the mold 20 into the positioning hole 193 of the loading fixture 10, so that the mold cavity 21 corresponds one-to-one with the mounting position 191. Pressing the first loading plate 11 compresses the spring 151, and the first loading plate 11 moves along the guide pin 153 toward the second loading plate 13. When the push rod 17 pushes the insert 30 from the two mounting posts 1913 into the mold cavity 21 of the mold 20, the push end 175 of the push rod 17 pushes the insert 30 into place along the third through hole 1915. When the second rod body 182 of the limiting rod 18 abuts against the second feeding plate 13, the insert 30 is pushed into place, the first feeding plate 11 is released, the spring 151 extends, and pushes the first feeding plate 11 to move away from the second feeding plate 13 along the direction of the guide post 153. When the limiting end 1533 of the guide post 153 abuts against the second feeding plate 13, the first feeding plate 11 is reset and stops moving.
[0040] It is understandable that the first feeding plate 11 can be pressed manually, or the first feeding plate 11 can be driven by a cylinder or motor, or PLC control or stepper motor can be used to precisely control the displacement of the first feeding plate 11.
[0041] Compared to the prior art, the feeding fixture 10 provided in this embodiment of the utility model is equipped with the pre-installed plate 19. The pre-installed plate 19 is provided with an installation position 191 corresponding to the cavity 21 of the mold 20. The insert 30 can be pre-installed in the installation position 191. When injection molding is required, the feeding fixture 10 with the pre-installed insert 30 can be assembled into the mold 20 for injection molding, which improves production efficiency and does not require occupying the injection molding production time of the mold 20.
[0042] The push rod 17 is fixed to the first feeding plate 11 and passes through the second feeding plate 13. Responding to pressure from the first feeding plate 11, it inserts into the mounting position 191, pushing the insert 30 from the mounting position 191 into the mold cavity 21 of the mold 20, thus enabling batch pushing of the inserts 30 into place. Therefore, when using the feeding fixture 10, it is only necessary to simply install the insert 30 in the mounting position 191 without it falling off, and then the push rod 17 pushes the inserts 30 into place in batches, eliminating the need to carefully check the positioning degree of each insert 30, making the operation convenient.
[0043] The limiting rod 18 is set to limit the downward pressing distance of the first feeding plate 11, which can prevent excessive pressure from damaging the insert 30 and the mold 20.
[0044] This utility model also provides a feeding device, including the above-mentioned feeding fixture 10 and the above-mentioned mold 20.
[0045] The above description is only a part of the embodiments of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the contents of the utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
