Specific implementation mode
[0022] An injection molding method, which includes the following steps:
[0023] Step 1: Obtain an injection molded product through injection molding;
[0024] Step 2: Align both sides of the formed injection molded product by flipping the position of the injection molding system;
[0025] Step 3: Clamp both sides of the injection molded product by using the injection molding system;
[0026] Step 4: Grind the burrs on the surface of the injection molded product through the injection molding system.
[0027] This part is based on Figures 2-4The working process described is as follows: When in use, first, the plastic particles are heated and melted by the injection barrel 101 and injection molding work is carried out. After that, to facilitate deburring the injection-molded finished product, first, the injection-molded finished product should be accurately aligned and clamped. Further, the electric push rod 102 rotatably connected to the middle of the injection barrel 101 is driven, so that the pulling rod 104 fixedly connected to the movable end of the electric push rod 102 by a flange moves to the right, and synchronously pushes the main clamp seat 201 and the sub-clamp seat 202 located on the front and rear sides of the pulling rod 104 to rotate on the two movable ends of the double-sided push rod I 203, and with this as the center point, the main clamp seat 201 and the sub-clamp seat 202 perform a flipping operation to facilitate vertically aligning with the formed injection-molded finished product. Then, at this time, by driving the double-sided push rod I 203, the main clamp seat 201 and the sub-clamp seat 202 located at the two movable ends of the double-sided push rod I move towards the middle. To facilitate the consistent movement of the main clamp seat 201 and the sub-clamp seat 202, the main clamp seat 201 and the sub-clamp seat 202 are connected by sliding sleeves when sliding on the front and rear sides of the pulling rod 104, and then the formed finished product parts are clamped evenly from both sides to prevent the formed finished product parts from falling off after injection molding and to facilitate timely deburring work.
[0028] The upper and lower sides of the main clamp seat 201 and the sub-clamp seat 202 are slidably connected to each other.
[0029] A rectangular strip hole is provided in the middle of the main clamp seat 201 and the sub-clamp seat 202 in the vertical direction.
[0030] A mold part 105 is fixedly connected to the right side of the clamping frame 103.
[0031] This part is based on Figures 2-10 The working process described is as follows: A mold part 105 is fixedly connected to the right side of the clamping frame 103 by bolts. This mold part 105 is convenient for forming a strip-shaped injection-molded part. In this application, the injection-molded finished product part takes the strip-shaped injection-molded part as an example for description.
[0032] A convex seat 204 is fixedly connected to the middle of the outer sides of the main clamp seat 201 and the sub-clamp seat 202. A fixed end of a double-sided push rod II 301 is fixedly connected to each convex seat 204. A lifting seat 302 is fixedly connected to each of the two movable ends of each double-sided push rod II 301. The two lifting seats 302 located at the rear side are respectively slidably connected to the upper and lower sides of the rectangular strip hole of the sub-clamp seat 202, and the two lifting seats 302 located at the front side are respectively slidably connected to the upper and lower sides of the rectangular strip hole of the main clamp seat 201.
[0033] This part is based on Figures 2-10The working process expressed in it is as follows: In the middle of the outer sides of the main clamping seat 201 and the auxiliary clamping seat 202, a convex seat 204 is fixedly connected by bolts. The convex seat 204 is fixedly connected to the fixed ends of two double-direction push rods II 301 through flanges. When in use, when clamping the injection molded product, the lifting seats 302 on the two movable ends of each double-direction push rod II 301 are driven to move closer to the middle, and the right-angle parts on each lifting seat 302 extending backward are used to clamp the injection molded product. When clamping, the long strip holes on the main clamping seat 201 and the auxiliary clamping seat 202 provide sliding limits for the lifting movement of each lifting seat 302.
[0034] The four lifting seats 302 are symmetrically arranged in a mirror image with the fixed ends of the two double-direction push rods II 301 to which they are fixedly connected as the mirror center.
[0035] This part is based on Figures 2-10 The working process expressed in it is as follows: The four lifting seats 302 are sequentially symmetrically arranged in a mirror image, which is convenient for fixedly clamping the four corners of the injection molded product, thereby improving stability.
[0036] Each lifting seat 302 is provided with a right-angle part, which extends backward, and a long strip hole is provided at the extending part.
[0037] A moving seat 401 is slidably connected in the long strip hole of each lifting seat 302. On the left and right sides of the bottom of each moving seat 401, a rotating rotating rod 402 is rotatably connected. A grinding wheel 403 is fixedly connected to each rotating rod 402.
[0038] A lead screw 303 is rotatably connected to each lifting seat 302, and each lead screw 303 is respectively in transmission connection with the top of each moving seat 401 in sequence.
[0039] This part is based on Figures 2-10 The working process expressed in it is as follows: When deburring the clamped injection molded product, the top of each lead screw 303 is fixedly connected to the output shaft of a motor through a coupling, and then each motor is driven to drive each lead screw 303 to rotate. At this time, each moving seat 401 threadedly connected to each lead screw 303 can be driven to move along the long strip hole on each lifting seat 302 as a track;
[0040] And a first motor is fixedly connected to each moving seat 401. The rotating shaft on each first motor is drivingly connected to four belts 404 and two rotating rods 402 located on each moving seat 401 through pulleys. When grinding the injection molded products, the first motors on each moving seat 401 are driven to drive the rotating rods 402 drivingly connected thereto to rotate by each belt 404. Thus, when the moving seat 401 moves along the long hole direction, it is convenient to grind the injection molded product clamped by the lifting seat 302, preventing burrs from affecting the appearance of the overall injection molded product and improving the quality of each formed injection molded product.
