Technical Field

[0001] The utility model relates to the technical field of car lamp injection molding production, in particular to a novel device for removing water inlets at the rear end of injection molding. Background Art

[0002] In the automated production of car lights, injection molding is a vital part of production activities. The sprue is where the plastic is injected into the mold during the injection molding process. It is usually connected to the product, so it needs to be removed to ensure the product's surface aesthetics, functionality and processing accuracy. The existence of the sprue is essential but has no use for the product, so it is necessary to remove it.

[0003] However, there is currently a lack of effective nozzle removal devices, and nozzles are generally removed manually or with the help of tools. The efficiency is generally low, time-consuming and labor-intensive, and the labor intensity is high. In addition, the product is easily damaged during removal, and insufficient precision will affect the quality of the final product. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel device for removing the water outlet at the rear end of injection molding, which can automatically cut off the water outlet of the product with higher efficiency and precision.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A novel injection molding rear end water inlet removal device comprises a frame, a driving mechanism arranged on the frame, and a lower mold positioning component arranged on the driving mechanism;

[0007] A main cylinder with an output end facing downward is installed on the frame through a cylinder stand, and an upper die cutting assembly located above a lower die positioning assembly is provided at the output end of the main cylinder;

DETAILED DESCRIPTION

[0032] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0033] like Figure 1-6As shown, in this embodiment, a new type of injection molding rear end water inlet removal equipment is provided, which is mainly composed of a frame 1, a driving mechanism 2, a lower mold positioning assembly 3, an upper mold cutting assembly 4, a main cylinder 5 and other components.

[0034] Among them, the driving mechanism 2 is arranged at the top center of the frame 1. The driving mechanism 2 is specifically composed of a rodless cylinder 20 installed on the top of the frame 1 and a slide 21 installed at the output end of the rodless cylinder 20. The lower mold positioning assembly 3 is installed on the slide 21. The rodless cylinder 20 can drive the lower mold positioning assembly 3 to move forward and backward through the slide 21.

[0035] The lower mold positioning assembly 3 is specifically composed of a lower mold plate 30 mounted on the slide 21, a plurality of profiling limit blocks 31 arranged on the lower mold plate 30, two rotating cylinders 32 arranged on the lower mold plate 30, and other components, and a pressing rod 33 is installed on each rotating cylinder 32. The plurality of profiling limit blocks 31 can be used to position and place the injection molded product to be cut, and the two rotating cylinders 32 can control the pressing rod 33 to press down and compact the injection molded product, so as to facilitate the upper mold cutting assembly 4 to perform subsequent cutting work.

[0036] In order to control the upper mold cutting assembly 4 to cut off the water outlet of the injection molded product, the main cylinder 5 with the output end facing downward is installed on the frame 1 through the cylinder stand 6, and the upper mold cutting assembly 4 is installed on the output end of the main cylinder 5 through the adapter 50. The upper mold cutting assembly 4 is located above the lower mold positioning assembly 3 as a whole.

[0037] The upper die cutting assembly 4 is specifically composed of an upper die plate 40 installed at the output end of the main cylinder 5, a plurality of knife seats 41 arranged at the bottom of the upper die plate 40, and a punch 42 installed on each knife seat 41. When the rodless cylinder 20 drives the lower die positioning assembly 3 to the bottom of the upper die cutting assembly 4, the upper die plate 40 is moved downward by the main cylinder 5, and the sprue of the injection molded product after being pressed and positioned can be cut through the plurality of punches 42. The plurality of punches 42 correspond to the various sprue positions of the injection molded product, so the upper die cutting assembly 4 can be cut cleanly at one time when it moves downward for cutting, which is highly efficient.

[0038] In order to improve the cutting effect and ensure the success rate, in this embodiment, a heating rod 43 is provided in each punching knife 42, and a thermocouple is connected to the heating rod 43. The punching knife 42 can be heated by the heating rod 43, thereby improving the cutting effect.

[0039] In order to improve the accuracy of cutting, in this embodiment, positioning guide pillars 34 are provided at the four corners of the lower template 30, and positioning guide sleeves 44 corresponding to the positioning guide pillars 34 are provided at the four corners of the bottom of the upper template 40. When the upper mold cutting assembly 4 moves down for cutting, the four positioning guide pillars 34 can be matched and engaged with the four positioning guide sleeves 44, thereby ensuring the accuracy of cutting. In addition, the lower mold positioning assembly 3 positions the injection molded product through a plurality of contoured limit blocks 31, and is pressed by the pressure rod 33, which can ensure the stability and accuracy of the injection molded product during cutting, thereby ensuring the quality of the injection molded product after cutting.

[0040] In order to facilitate the replacement of different types of lower mold positioning components 3 and upper mold cutting components 4, the present embodiment is provided with nylon handles 9 on both sides of the lower mold plate 30 and the upper mold plate 40 to facilitate manual lifting of the entire mold for replacement.

[0041] In order to ensure the alignment and stability of the lateral movement of the lower mold positioning assembly 3, the present embodiment further connects the bottom of the lower mold plate 30 to the frame 1 through a guide rail mechanism 7, which specifically consists of a guide rail 70 mounted on the top of the frame 1 and a slider 71 slidably mounted on the guide rail 70, and the bottom of the lower mold plate 30 is mounted on the slider 71. The design of the guide rail mechanism 7 can ensure the accuracy of the station switching of the lower mold positioning assembly 3.

[0042] In order to prevent the lower die positioning assembly 3 from overshooting or falling off when moving forward, a buffer mechanism 8 suitable for limiting the lower die positioning assembly 3 is further provided at the top front end of the frame 1 in this embodiment. The buffer mechanism 8 is specifically composed of a support 80 installed on the top of the frame 1, and an oil pressure buffer 81 and a hard limit screw 82 installed on the support 80. The oil pressure buffer 81 can buffer and limit the end surface of the lower mold plate 30, and the hard limit screw 82 can prevent the lower die positioning assembly 3 from falling off due to excessive impact.

[0043] Through the above design, it can be seen that when this embodiment is working, an external manipulator can be used to clamp the injection molded product to be cut off and place it on the lower mold positioning component 3, and multiple contour limit blocks 31 can be used to limit and stabilize the injection molded product, and the two rotating cylinders 32 can be used to control the pressure rod 33 to press down and compact the injection molded product, and then the driving mechanism 2 drives the lower mold positioning component 3 to move back to just below the upper mold cutting component 4, and then the main cylinder 5 controls the upper mold cutting component 4 to move down to cut the injection molded product on the lower mold positioning component 3. The whole process is performed automatically through mechanization, without the need for manual cutting, saving time and effort, and improving work efficiency. The lower mold positioning component 3 can stably position the injection molded product, so the cutting accuracy is higher, which can ensure the quality of the finished product.
