Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and more specifically, to a gate stamping equipment for injection molded parts. Background Technology

[0002] Injection molding gate stamping equipment is a mechanical device used after the injection molding process to process the gates on injection molded parts. The gate is the channel in the injection mold that connects the main runner and the cavity. After injection molding, excess plastic material may remain at the gate, and there may be defects in appearance and quality. Injection molding gate stamping equipment uses specific molds and stamping actions to cut, trim, or optimize these gates, ensuring that the injection molded parts meet quality and appearance standards.

[0003] If the injection molding gate stamping equipment does not have an external enclosure as a protective mechanism, operators may inadvertently put their hands or other body parts into the stamping area. Since the stamping equipment usually moves quickly and forcefully, this can lead to serious crushing injuries, cuts, and other accidents. Especially during equipment operation, operators may approach or come into contact with dangerous areas due to the lack of clear boundary warnings. Therefore, it is necessary to design an injection molding gate stamping equipment with strong adaptability to solve the above problems. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an injection molding part gate stamping equipment. When the template is displaced during operation, the side baffles on both sides of the template protect the left and right sides, and the space in front of it is protected by the front baffle assembly, forming a physical barrier between the operator and the processing area, so that the stamping area of ​​the stamping equipment table can maintain a good protective state when it is in operation.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A gate stamping device for injection molding includes a stamping machine table. Four rectangular vertical supports are fixedly connected to the upper end of the stamping machine table. A top horizontal plate is installed on the upper side of the outer ends of the vertical supports. A hydraulic press is fixedly connected to the upper end of the top horizontal plate. A stamping template that slides outside the vertical supports is fixedly connected to the output end of the hydraulic press. Electric slide rails are symmetrically fixedly connected to the left and right sides of the upper end of the stamping machine table. A displacement lower template is fixedly connected to the output ends of the two electric slide rails. The displacement lower template cooperates with the stamping template. Side baffles located outside the vertical supports are symmetrically fixedly connected to the left and right sides of the upper end of the stamping machine table. A horizontal bar is fixedly connected to the front end of the side baffle. A front baffle assembly is provided between two horizontal bars. The front baffle assembly includes multiple strip-shaped deformation horizontal pieces arranged equidistantly from top to bottom. An electromagnetic inner strip is fixedly connected to the lower end of each strip-shaped deformation horizontal piece, and a metal inner strip is fixedly connected to the upper end of each strip-shaped deformation horizontal piece.

[0007] Furthermore, a self-resetting hinge is installed between two adjacent strip-shaped deformable cross sections, and the corresponding upper and lower metal inner strips and electromagnetic inner strips are magnetically connected.

[0008] Furthermore, the front bumper assembly is located directly in front of the stamping die and the lower displacement die, and a scrap frame is fixedly connected to the rear end of the stamping equipment table.

[0009] Furthermore, a rotating shaft is installed at the rear end of the displacement template, and a follower discharge plate is rotatably connected to the rear end of the rotating shaft.

[0010] Furthermore, the follow-up discharge plate is located directly above the waste frame, and a flexible storage bag is fitted inside the waste frame.

[0011] Furthermore, the waste frame has U-shaped latches on both the front and rear sides at the top, which engage with the opening of the flexible storage bag.

[0012] Furthermore, a weighing sensor block is fixedly connected to the lower inner wall of the waste container, and the weighing sensor block is located directly below the flexible storage bag.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) When the template is displaced, the side baffles on both sides of the template will protect the left and right sides. The space in front of the template will be protected by the front baffle assembly, forming a physical barrier between the operator and the processing area, thereby preventing any part of the operator's body from accidentally entering the stamping area. The working mode of the front baffle assembly is that when the template is displaced and the injection molded part gate above it is pushed outward, the electromagnetic inner strip in the front baffle assembly is de-energized, so that the front baffle assembly can follow the side baffles to push outward and the strip-shaped deformation strip can flexibly deform, so that most of the working area in front of the stamping template is kept in a protected state. When the template is displaced and reset, the deformed strip-shaped deformation strip returns to a plane under gravity, and the electromagnetic inner strip is energized to maintain a magnetic connection with the corresponding metal inner strip. This method can make it easy for the stamping equipment table to maintain a good protective state in the stamping area when it is in working state.

[0015] (2) At the same time, flexible storage bags are set in the waste box, making the collection of waste more convenient. When the flexible storage bags in the waste box are full, the operator only needs to tie the bags and remove them. There is no need to clean up the scattered waste as in the traditional waste collection method. The weighing sensor block in the waste box can record the weight data of the waste. If the weight of the waste fluctuates abnormally within a certain period of time, it may mean that there is a problem with the stamping equipment table. Through real-time monitoring of the weight of the waste, the staff can promptly discover abnormalities in the production process, make adjustments and maintenance in advance, and ensure the stable operation of production.

[0025] Example:

[0026] Please see Figure 1-3A gate stamping device for injection molding includes a stamping machine table 1. Four rectangularly distributed vertical supports 6 are fixedly connected to the upper end of the stamping machine table 1. A top horizontal plate 5 is installed on the upper side of the outer ends of the vertical supports 6. A hydraulic press is fixedly connected to the upper end of the top horizontal plate 5. A stamping template 4 that slides outside the vertical supports 6 is fixedly connected to the output end of the hydraulic press. Electric slide rails 2 are symmetrically fixedly connected to the left and right sides of the upper end of the stamping machine table 1. A displacement lower mold is fixedly connected to the output ends of the two electric slide rails 2. Plate 3, displacement template 3 and stamping template 4 cooperate with each other. Side baffles 13 located outside the vertical pole 6 are symmetrically fixedly connected to the upper left and right sides of the stamping equipment table 1. A crossbar 11 is fixedly connected to the front end of the side baffle 13. A front baffle assembly 12 is set between the two crossbars 11. The front baffle assembly 12 includes a plurality of strip-shaped deformation crossbars 14 arranged equidistantly from top to bottom. An electromagnetic inner strip 16 is fixedly connected to the lower end of the strip-shaped deformation crossbar 14, and a metal inner strip 15 is fixedly connected to the upper end of the strip-shaped deformation crossbar 14.

[0027] Please see Figure 1-4 A self-resetting hinge 17 is installed between two adjacent strip-shaped deformable horizontal pieces 14. The upper and lower corresponding metal inner strips 15 and electromagnetic inner strips 16 are magnetically connected. The front baffle assembly 12 is located directly in front of the stamping template 4 and the displacement lower template 3. A scrap frame 10 is fixedly connected to the rear end of the stamping equipment table 1. A rotating shaft 9 is installed at the rear end of the displacement lower template 3. A follower discharge plate 8 is rotatably connected to the rear end of the rotating shaft 9. The follower discharge plate 8 is located directly above the scrap frame 10. A flexible storage bag 19 is sleeved on the inner end of the scrap frame 10. U-shaped latches 18 are engaged on both the front and rear sides of the upper end of the scrap frame 10. The U-shaped latches 18 are engaged with the opening of the flexible storage bag 19. A weighing sensor block 20 is fixedly connected to the lower inner wall of the scrap frame 10. The weighing sensor block 20 is located directly below the flexible storage bag 19.

[0028] Please see Figure 1-4This scheme aligns the injection molded part's gate with the lower displacement mold plate 3, firmly fixing the injection molded part onto the stamping mold plate 4. The hydraulic press drives the stamping mold plate 4 to move towards the injection molded part's gate. The stamping mold plate 4 and the lower displacement mold plate 3 close the mold. After the injection molded part's gate stamping is completed, the upper mold is raised and the clamping device is released. The electric slide rail 2 drives the lower displacement mold plate 3 forward to remove the processed injection molded part from the worktable. When the vertical support 6 is below the stamping mold plate 4, the clamping mechanism is released again, allowing the scrap material to be positioned above the follower ejector plate 8. When the electric slide rail 2 resets for the next stamping operation, the follower ejector plate 8 rotates downward via the rotating shaft 9, allowing the scrap material to be removed. The material slides into the waste box 10 for collection. When the lower mold plate 3 is displaced, its side baffles 13 protect its left and right sides, and the space in front is enclosed by the front baffle assembly 12, forming a physical barrier between the operator and the processing area. This prevents any part of the operator's body from accidentally entering the stamping area, thus preventing serious injuries such as crushing and cutting caused by the immense stamping pressure. The front baffle assembly 12 operates as follows: when the lower mold plate 3, along with the injection molded part gate above it, is pushed outward, the electromagnetic inner strip 16 in the front baffle assembly 12 is de-energized, allowing the front baffle assembly 12 to... As the side baffle 13 pushes outward, the strip-shaped deformable horizontal piece 14 deforms flexibly, keeping most of the working area in front of the stamping template 4 in a protected state. When the template 3 resets under displacement, the deformed strip-shaped deformable horizontal piece 14 returns to a flat plane under gravity, energizing the electromagnetic inner strip 16 to maintain a magnetic connection with the corresponding metal inner strip 15. This method ensures that the stamping area of ​​the stamping equipment table 1 is well protected during operation, without limiting the stroke, speed, or other parameters of the stamping equipment table 1, thus ensuring that the production efficiency and product quality of the stamping equipment table 1 are not affected. Meanwhile, flexible storage bags 19 are set in the waste collection box 10, making waste collection more convenient. When the flexible storage bags 19 in the waste collection box 10 are full, the operator only needs to tie the bags and remove them. There is no need to clean up the scattered waste as in the traditional waste collection method. In addition, the weighing sensor block 20 in the waste collection box 10 can record the weight data of the waste. If the weight of the waste fluctuates abnormally within a certain period of time, it may mean that there is a problem with the stamping equipment table 1. Through real-time monitoring of the weight of the waste, the staff can promptly detect abnormalities in the production process, make adjustments and maintenance in advance, and ensure the stable operation of production.

[0029] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
