[0002] The hot runner manifold is the central component of the hot runner system, and its main function is to distribute the molten material transmitted by the main runner nozzle to each injection point nozzle through the sub-runners. For the manifold, the most important thing is that the internal runner orientation and its temperature uniformity determine the filling balance in the mold cavity. At present, the automotive industry is all about cost reduction and efficiency improvement. In order to reduce the mold cost and improve the production efficiency, the previous larger product parts were generally one cavity per mold, and now they will be made into two cavities or multiple cavities per mold. In this way, higher symmetry requirements are imposed on the manifold runners.
[0003] During the injection molding process of some larger product parts, the size of the manifold used, whether in length or width, has exceeded the machine stroke, and the thickness dimension also needs to match the machine space. Moreover, according to the design requirements of the manifold and the injection molding verification effect, under the condition of achieving excellent injection molding effects (excellent performance such as runner symmetry and fluidity), if the gate point position on the manifold is very close to the main runner, there is no space to add another runner, and it is more difficult to process the runner in a narrow space. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a manifold with a gate point adjacent to the main runner. By means of an insert and an injection runner inclinedly arranged therein to connect the gate and the main runner, the problem that it is not easy to process the injection runner due to the small gap caused by the close distance between the gate and the main runner can be perfectly solved, and the processing convenience is improved.

The insert is provided with an injection hole, an injection runner and an outlet hole. The injection hole is connected to the injection port. The outlet hole is connected to the main runner. The injection runner is inclined and connects the injection hole and the outlet hole.
[0006] As a further optimization, the positioning groove and the insert located therein vertically penetrate through the main runner, and a pair of glue outlet holes are respectively formed on opposite sides of the insert and are both communicated with the glue inlet runner. More preferably, the pair of glue outlet holes are communicated with each other, and the glue inlet runner is located at the middle position between the pair of communicated glue outlet holes, which can improve the processing convenience of the holes in the insert.

[0023] The following are specific embodiments of the present utility model in combination with the accompanying drawings, and the technical solutions of the present utility model will be further described. However, the present utility model is not limited to these embodiments.
[0024] As Figures 1 to 7 shown, a flow splitter plate with a glue inlet adjacent to the main runner includes a flow splitter plate body 1 and an insert 2. The flow splitter plate body 1 is provided with a main runner 110 and a plurality of sub-runners 120. The plurality of sub-runners 120 are located in the same plane as the main runner 110 and are connected to the main runner 110. A glue inlet 10 is formed on the side of the main runner 110 of the flow splitter plate body 1. The vertical projection of the glue inlet 10 is located on the side of the main runner 110. The flow splitter plate body 1 is provided with a positioning groove 100 connected to the glue inlet 10. The insert 2 is embedded in the positioning groove 100. The insert 2 is provided with a glue inlet hole 201, a glue flow channel 202 and a glue outlet hole 203. The glue inlet hole 201 is connected to the glue inlet 10, the glue outlet hole 203 is connected to the main runner 110, and the glue flow channel 202 is inclined and connects the glue inlet hole 201 and the glue outlet hole 203.
[0025] In the present utility model, due to the shape and specifications of the shunt plate body 1, the main runner 110 and the shunt runners 120 are in the same plane, and the glue inlet 10 is located beside the main runner 110. Since the thickness of the shunt plate 1 body is limited, a positioning groove 100 that can communicate with the glue inlet 10 is provided, and an insert 2 is installed in the positioning groove 100. The main runner 110 is communicated through the insert 2, that is, the glue inlet 10, the glue inlet hole 201, the glue flow channel 202, the glue outlet hole 203, and the main runner 110 are communicated in sequence to realize the diversion of the molten material. By means of the insert 2 and the inclined glue flow channel 202, it is possible to avoid directly arranging another flow channel on the shunt plate body 1 to connect the glue inlet 10 and the main runner 110, thereby avoiding the practice of arranging the flow channel in a narrow range due to the short distance between the glue inlet 10 and the main runner 110, and thus avoiding the complexity in processing; moreover, processing the positioning groove 100 communicating with the glue inlet 10 and / or the main runner 110, and the inclined glue flow channel 202 on the shunt plate body 1 has the characteristics of being easier to process, and the processing accuracy is easier to guarantee.
[0026] In the present utility model, by means of the insert 2 and the inclined glue flow channel 202 located therein to communicate the glue inlet 10 and the main runner 110, the problem that it is not easy to process the glue flow channel due to the small gap caused by the short adjacent distance between the glue inlet 10 and the main runner 110 can be perfectly solved, and the processing convenience is improved.
[0027] Preferably, as Figure 2 and 4 shown, the positioning groove 100 and the insert 2 located therein vertically penetrate the main runner 110. A pair of glue outlet holes 203 are respectively formed on opposite sides of the insert 2 and are both communicated with the glue flow channel 202. After the insert 2 vertically penetrates the main runner 110, the glue outlet holes 203 are docked and communicated with the main runner 110, which can ensure the accuracy and tightness of the docking; more preferably, a pair of glue outlet holes 203 are communicated with each other, and the glue flow channel 202 is located at the middle position of the pair of communicated glue outlet holes 203, as Figure 7 shown, that is, the communication with two glue outlet holes 203 is realized through one glue flow channel 202. On the one hand, it is convenient for processing and forming, and only secondary punching (horizontally punching to form a pair of glue outlet holes 203, obliquely punching to form the glue inlet hole 201, and the glue flow channel 202 connecting the glue inlet hole 201 and the glue outlet hole 203) needs to be carried out on the insert 2. On the other hand, it can ensure the uniformity of the molten material flowing in two directions in the main runner 110.
[0028] According to the positional relationship between the glue inlet 10 and the main runner 110, as well as the sizes of the positioning groove 100 and the insert 2, the included angle between the glue flow channel 202 and the vertical plane can be set to 30° - 50° to ensure the appropriate size of the insert and the length of the glue flow channel 202.
[0029] Combined withFigure 2 and Figure 5 As shown in Figure 5 , for the precise positioning and installation of the insert 2, an extension groove 10a can be provided on the positioning groove 100, and a positioning cap 21 is provided at the upper end of the insert 2. The positioning cap 21 is embedded in the extension groove 10a to ensure the installation depth of the insert 2 and ensure that the glue outlet hole 203 and the main runner 110 are located in the same horizontal plane.
[0030] A positioning cut surface 211 is provided on the positioning cap 21, and a mating surface matching the positioning cut surface 211 is provided on the inner wall of the extension groove 10a. The positioning cut surface 211 abuts against the mating surface, which can ensure that the glue outlet hole 203 is accurately docked with the main runner 110. In addition, an indication mark 213 is provided on the insert 2. When a pair of connected glue outlet holes 203 are not located in the diameter direction of the insert 2, through the direction or position indication of the indication mark 213, the dislocation of the glue outlet hole 203 and the main runner 110 can be avoided and they cannot be docked.
[0031] The insert 2 further includes a pin (not shown). A first pin hole 212 is provided on the positioning cap 21, and a second pin hole 10b communicating with the first pin hole 212 is provided on the extension groove 10a. The pin extends into the first pin hole 212 and the second pin hole 10b, and the insert 2 can be firmly installed on the manifold body 1.
[0032] As Figure 1 and 3 shown, the manifold body 1 in the present utility model includes a first support plate 11 for carrying the main runner 110 and a plurality of second support plates 12 connected to the first support plate 11 and for carrying the sub-runners 120. The number of the second support plates 12 (sub-runners 120) is set according to the actual working conditions. In this embodiment, there are six sub-runners 120. Each sub-runner 120 includes a front section runner 1201 communicating with the main runner 110 and a rear section runner 1202 communicating with the front section runner 1201. Every three sub-runners 120 share a front section runner 1201. The molten material is branched through the front section runner 1201 to the rear section runner 1202, and then discharged through a nozzle communicating with the first discharge hole 121, which can ensure that the travel of the molten material in the sub-runner 120 is equal. In addition, a second discharge hole 111 can also be provided at a position on the main runner 110 away from the gate 10 for discharging through a nozzle, so as to realize the injection molding of multiple or various products.
[0033] To ensure the uniform flow performance of the molten material on the manifold body 1, heating wires 1a are provided on the sides of the main runner 11 and the sub-runners 120.
[0034] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
