[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 2-6 In an embodiment of the utility model, an injection mold of a collimator housing includes an upper mold 1 and a lower mold 2 that are butt-jointed with each other, a glue feeding mechanism disposed on the upper mold 1, and an ejection mechanism disposed on the lower mold 2, and multiple groups of station groups 3 are disposed between the upper mold 1 and the lower mold 2 that are butt-jointed with each other, and the multiple groups of station groups 3 are arranged in a ring array, and each group of the station groups 3 includes a first station 4 and a second station 5 that are symmetrically arranged at intervals;

[0030] The glue feeding mechanism includes a main flow channel 6 arranged on the upper mold 1 and a primary runner 7 and a secondary runner 8 arranged on the parting surface of the lower mold 2, wherein the main flow channel 6, the primary runner 7 and the secondary runner 8 are sequentially connected, wherein a plurality of primary runners 7 are provided, and the plurality of primary runners 7 correspond one-to-one to the plurality of station groups 3, and the secondary runner 8 includes a first runner 9 corresponding to the first station 4 and a second runner 10 corresponding to the second station 5, and the first runner 9 and the second runner 10 are symmetrically arranged with the primary runner 7 as the center;

[0031] The ejection mechanism includes an ejector plate 11 movably connected to the lower mold 2 and a first ejector 12, a second ejector 13 and a third ejector 14 arranged on the ejector plate 11, the first ejector 12 corresponds to the main channel 6, the second ejector 13 corresponds to the first branch channel 9 and the second branch channel 10, and the third ejector 14 corresponds to the first station 4 and the second station 5.

[0032] In the technical solution of the utility model, multiple groups of workstation groups 3 are arranged in a circular array, and each group of workstation groups 3 includes a first workstation 4 and a second workstation 5 that are symmetrically arranged at intervals. According to this design, through the main flow channel 6, the first-level branch flow channel 7 and the second-level branch flow channel 8 connected in sequence, and the main flow channel 6 is the center, the first-level branch flow channel 7 corresponds to the workstation group 3, and the second-level branch flow channel 8 is divided into a first branch flow channel 9 and a second branch flow channel 10, and the first branch flow channel 9 corresponds to the first workstation 4, and the second branch flow channel 10 corresponds to the second workstation 5, so that after the product is formed, the main flow channel 6, the first-level branch flow channel 7, the first branch flow channel 9 and the second branch flow channel 10 can be connected to form a runner waste of an integrated structure, and multiple products can be connected with the flow channel waste. The runner waste materials are connected to form a whole, combined with the first ejector 12 corresponding to the main runner 6, the second ejector 13 corresponding to the first branch runner 9 / the second branch runner 10, and the third ejector 14 corresponding to the first station 4 / the second station 5. That is, when the product is demoulded, the first ejector 12, the second ejector 13 and the third ejector 14 can work together to eject multiple products and the runner waste materials of the integrated structure, so that it is convenient for manual or mechanical hands to take out multiple products at one time, which is conducive to improving production efficiency. The first ejector 12, the second ejector 13 and the third ejector 14 can be docked in a targeted manner, so as to effectively ensure that the runner waste materials and the multiple products can be ejected together, thereby ensuring the feasibility of taking out multiple products at one time after demoulding.

[0033] In the embodiment of the utility model, a water inlet 15 is formed between the connection between the first station 4 and the first branch channel 9 , and between the connection between the second station 5 and the second branch channel 10 , and the second ejector pin 13 is arranged close to the water inlet 15 .

[0034] Through this arrangement, the second ejector pin 13 will not directly act on the position of the product's sprue 15, thereby effectively preventing the product and runner waste from breaking at the sprue 15 during the demoulding process, thereby affecting the removal of multiple products and runner waste together. In addition, the second ejector pin 13 is arranged close to the position of the sprue 15, which effectively enhances the force of ejecting the product, which is beneficial for the product to be separated from the first station 4 / the second station 5.

[0035] In the embodiment of the utility model, the glue feeding mechanism further includes an extended runner 16 arranged on the parting surface of the lower mold 2, the extended runner 16 is connected to the primary runner 7 and the main runner 6, and the extended runner 16 is located between two adjacent primary runners 7;

[0036] The extended branch channel 16 is not connected to the first workstation 4 or the second workstation 5 .

[0037] Specifically, the extended branch channel 16 is in a straight line or fan shape.

[0038] By extending the branch channel 16, the connection strength between the adjacent primary branch channels 7 and the main channel 6 is effectively strengthened, that is, the overall volume and strength of the integrated flow channel waste are effectively increased, which is beneficial to avoid the flow channel waste from splitting during the process of ejecting products and flow channel waste.

[0039] In the embodiment of the utility model, the workstation groups 3 are provided with four groups, the primary diversion channels 7 and the extended diversion channels 16 are respectively provided with four, and the four primary diversion channels 7 and the four extended diversion channels 16 are connected to form a cross-shaped structure.

[0040] In the embodiment of the utility model, the first branch channel 9 / the second branch channel 10 are arranged in an arc-shaped transition.

[0041] It is understandable that the main channel 6 and the first-level branch channel 7 are both straight channels or substantially straight channels, so that the molten injection material can flow quickly into the mold through the arc-shaped transition setting of the first branch channel 9 / the second branch channel 10, so as to play a buffering role when entering the mold cavity, that is, between the first station 4 / the second station 5, thereby avoiding uneven flow of the injection material, resulting in quality problems such as heat melt marks and bubbles in the product, affecting the reliability and aesthetics of the product.

[0042] In the embodiment of the utility model, an assembly cavity 17 is opened in the lower mold 2, and an assembly block 18 is slidably connected in the assembly cavity 17. A molding insert 19 corresponding to the first station 4 / the second station 5 is arranged on the assembly block 18. The molding insert 19 is connected to the third ejector 14, and a slideway 20 corresponding to the second ejector 13 is opened on the molding insert 19.

[0043] The third ejector 14 drives the assembly block 18 and the molding insert 19 thereon to slide, thereby realizing the ejection of the product. The synchronous assembly block 18 can have a slideway 20 corresponding to the second ejector 13, so as to accurately determine the sliding path of the second ejector 13 and increase the sliding stability of the second ejector 13, thereby effectively avoiding the position deviation of the second ejector 13 during ejection, which may cause the product and the runner waste to be broken and separated at the connection between the sprue 15, thereby ensuring the success rate of taking out multiple products at one time after demolding.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
