[0077] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0078] This application provides the following technical solutions:

[0079] A tilting top assembly and an anti-shrinkage tie rod injection molding mechanism, comprising the steps of:

[0080] F1. According to the products to be processed by injection molding, the corresponding shapes of the products are processed on the same mold;

[0081] F2. Adjust the injection molding machine and the mold so that the mold is placed horizontally;

[0082] F3, corresponding to the product on the mold, including a ejector assembly, which is set at the ejection position of the product; an ejector assembly, which is connected to the ejector assembly, and a matching gap is reserved between the ejector assembly and the ejector assembly; an ejector seat assembly, which is connected to the ejector assembly and is set at one end of the ejector assembly away from the ejector assembly;

[0083] F4. Set a reserved gap as needed, and reserve a matching gap between the ejector assembly and the ejector head assembly to ensure that the ejection operation can be completed within the ejection distance range while the ejection head assembly and the product shrink, effectively preventing the product from being pulled out of the mold;

[0084] F5. After the above debugging is completed, the product is injection molded.

[0085] In order to solve the problems in the background technology, after the product is injection molded, it shrinks and deforms due to the product's own shrinkage and deformation. Due to the limitation of the structural position, it is impossible to design a complex ejection structure, which leads to the problem of stretching and deformation of the product after demolding, seriously affecting its appearance and size.

[0086] This solution combines the pushing motion of the inclined ejector head and the inclined ejector rod in the ejector head assembly, and reserves a gap between the inclined ejector head and the inclined ejector rod for upward and downward movement. When the product is ejected, the inclined ejector rod drives the inclined ejector head to eject one step later. This allows the product to have a buffer in the mold. When the product at this position is cooled and then ejected, it can avoid the product at this position from being pulled or being pulled out due to shrinkage problems. When the ejection is completed and returned to the mold, the inclined ejector rod drives the inclined ejector head to move normally.

[0087] Therefore, this solution proposes a processing method in which the gap between the inclined ejector head and the inclined ejector rod is adjusted according to different operation requirements so that the two can complete the ejection processing at the same time.

[0088] In the above embodiment, the ejection distance setting in step F4 takes into account the setting needs of different states. The width of the limit block on the inclined ejector head and the width of the upper slide groove opened at the upper end of the inclined ejector rod are L and L, respectively. a and L b , by taking the raw material PRT resin as an example, satisfying L a -L b ;

[0089] Reference formula for adjustment:

[0090] ΔL=L a -L b

[0091] Where ΔL is the width dimension L of the limit block a The upper end of the inclined ejector rod is provided with an upper slot width L b The resulting gap difference;

[0092] ΔL=2-4mm

[0093] Among them, ΔL is the shrinkage of the product after being cooled out of the mold due to the physical properties of the raw material resin + 1mm; it is also the difference between the width of the upper slide groove opened at the upper end of the inclined ejector and the width of the limit block;

[0094] On the basis of the above implementation scheme, the setting of the ejection distance in step F4 further includes state 2, characterized in that the setting of the ejection distance in step F4 further includes:

[0095] State 2: The ejection distance of the ejector assembly is set to the same horizontal height as the product is ejected; when this condition is met, the ejection distance of the ejector assembly is a, and the distance from the ejection limit of the ejector plate where the ejector seat is located to the plate where the product is located is b;

[0096] Under the ejection distance requirement of state 2, the formula is satisfied.

[0097] b=tanα·a

[0098] α is the angle between the top rod assembly and the top seat assembly;

[0099] Based on the above implementation scheme, see Figure 2 , Figure 3 , Figure 6 and Figure 7 The mandrel assembly 1 includes an inclined mandrel 11 of a block structure, which is movably connected to the upper end of the mandrel assembly 2; a matching gap is set at the connection between the inclined mandrel 11 and the mandrel assembly 2.

[0100] The push rod assembly 2 includes an inclined push rod 21, which is a rod body structure. A sliding structure is provided between the upper end of the inclined push rod 21 and the connection between the inclined push head 11, and the lower end of the inclined push rod 21 is movably connected to the top seat assembly 3.

[0101] The top seat assembly 3 includes a base 31 , and a horizontal downward sliding groove 311 is formed on the base 31 ; a lower sliding block 32 is slidably connected in the downward sliding groove 311 , and the lower end of the inclined ejector rod 21 is hinged to the lower sliding block 32 .

[0102] Because this solution is applied to the inclined ejection process, it is necessary to consider the change of the position of the entire inclined ejector rod 21 when the mold is opened and closed, so a movable ejector assembly 3 is provided. On this basis, if the ejection direction of this solution is not inclined ejection, but vertical ejection, the ejector assembly 3 can still adapt without making any changes.

[0103] Based on the above implementation scheme, see Figure 6 The upper end of the inclined ejector rod 21 is provided with an upper slide groove 211; the inclined ejector head 11 is provided with a limit block 12, and the limit block 12 is slidably connected with the upper slide groove 211 of the inclined ejector rod 21. The sliding movement range of the limit block 12 in the upper slide groove 211 is the aforementioned 2-4mm matching clearance.

[0104] This solution basically only needs to satisfy that there is a matching gap between the inclined ejector rod 21 and the inclined ejector head 11, and the two can also be linked to each other. Various specific solutions can be adopted.

[0105] Based on the above implementation scheme, see Figure 6 , this scheme provides a specific structure for the setting of the limit block 12. The inclined top block 11 is provided with a first slot 111 and a second slot 112. The first slot 111 is opened inside the inclined top block 11, and the first slot 111 extends downward to form an open socket. The upper end of the inclined top rod 21 can be inserted into the first slot 111 and is slidably connected with the first slot 111. The second slot 112 is opened on the side of the inclined top block 11, and the second slot 112 forms a through slot facing the first slot 111. The limit block 12 is set in the second slot 112, one end of the limit block 12 extends into the first slot 111, and the end of the limit block 12 located inside the first slot 111 is slidably connected with the upper slide groove 211.

[0106] The first slot 111 provides sufficient activity space for the lift rod 21, and the specific activity clearance matching restriction is realized by the limit block 12 combined with the slide groove 211. Therefore, the sliding distance of the limit block 12 in the upper slide groove 211 forms a matching clearance.

[0107] On the basis of the above implementation scheme, the limiting block 12 is a wedge-shaped block, and the second slot 112 corresponds to the shape of the limiting block; the limiting block 12 is fixedly connected to the inner wall of the second slot 112 .

[0108] See also Figure 8 A specific implementation form is given in the accompanying drawings, in which an opening area is reserved at one end of the second slot 112 facing the first slot 111, and a boss structure is provided at the end of the limit block 12, and the boss can be inserted into the opening area. The opening area corresponds to the slide groove 211 of the inclined ejector rod 21, so the boss structure of the wedge block 12 can be slidably connected with the slide groove 211 of the inclined ejector rod 21.

[0109] A threaded hole is provided in the first slot 112. The block body of the limiting block 12 can be fixed in the second slot 112 through the threaded hole.

[0110] The reason why the limit block 12 is a wedge block is that the wedge block has better binding force. By setting a bolt fixing structure, the positional relationship between the boss structure, which is also a wedge, and the slide groove 211 can be changed by adjusting the depth of the wedge block in the second slot 112. The longer the limit block 12 enters the slide groove 211, that is, when the end face of the boss is against the bottom of the slide groove 211, the smaller the movable range between the inclined ejector rod 21 and the inclined ejector head 11. If the limit block 12 moves slightly outward, the movable range of the inclined ejector rod 21 will be slightly larger. Because this solution considers more precise injection molding, the small displacement here is sufficient to meet production needs.

[0111] On the basis of the above embodiment, the push rod assembly 2 further includes a guide member 22, which is sleeved and slidably connected to the rod body of the inclined push rod 21, and is fixedly connected to an external device. The guide member 22 is used to protect and guide the inclined push rod 21.

[0112] On the basis of the above implementation scheme, pin holes can also be correspondingly provided between the inclined ejector head 11 and the inclined ejector rod 21. When relative displacement between the two is not required, a fixing pin can be inserted into the pin hole to make the two fixedly connected.

[0113] Based on the above implementation scheme, see Fig. 9 and Fig.10The present invention also provides an anti-shrinkage injection molding tie rod mechanism, which adopts the inclined ejector assembly as mentioned above, including a first half and a second half, the first half can move toward or away from the second half, the ejector head assembly 1 of the inclined ejector assembly is arranged on the first half, and the first half corresponds to the inclined ejector rod 21 of the ejector rod assembly 2. A through groove is opened, and the base 31 of the ejector seat assembly 3 is fixedly connected to the second half.

[0114] Eject the product according to actual needs, and set up multiple inclined ejector assemblies at the corresponding structural positions of the selected products. Make sure that there is enough space for product shrinkage at each location. Then insert the inclined ejector head 11 into the undercut position of the product, and insert the inclined ejector rod 21 into the inclined ejector head 11 to prop up the product. Support the product to prevent it from detaching from the inclined ejector head 1 at that location, and ensure that when the mold retracts, the inclined ejector rod 2 and the lower slider 32 in the ejector seat assembly can follow the mold movement to return to the original position. By setting up the inclined ejector assembly, the corresponding product position can be ejected later than other similar structures, so that the product can be fully contracted in the mold cavity, preventing the product from being strained and deformed due to self-contraction of the product and the matching position of the inclined ejector during ejection.

[0115] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
