Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This utility model provides, for example Figure 1-5 Shown:
[0035] Example 1:
[0036] An injection molding structure that facilitates demolding includes:
[0037] Countertop 1;
[0038] Bottom mold 2, which is set on top of table 1;
[0039] Top mold 3 is located on top of bottom mold 2;
[0040] Demolding component 4 is disposed on the inner wall of the bottom end of the bottom mold 2 and is used to assist in demolding.
[0041] The movable component 5 is located on one side of the bottom mold 2 and is used to move the position of the product.
[0042] It should be noted that a molding cavity is provided on the side opposite to the top mold 3 of the bottom mold 2, and a material inlet is provided on the top of the top mold 3. When a product needs to be injection molded, the bottom mold 2 and the top mold 3 are first fitted together, and then the material is fed into the inside of the molding cavity through the material inlet, and the required product is formed through the molding cavity.
[0043] Specifically, demolding component 4 includes:
[0044] Mounting hole 402 is formed on the inner wall of the bottom end of bottom mold 2;
[0045] The insert 401 is inserted into the inside of the push rod 403;
[0046] Push rod 403 is fixedly connected to the bottom end of inner insert 401;
[0047] Cylinder 405 is fixedly connected to the bottom of the platform 1, and the output end of cylinder 405 is fixedly connected to the bottom end of push rod 403.
[0048] Specifically, an insertion hole 404 is provided on the inner wall at the bottom of the mounting hole 402, and the push rod 403 is inserted and connected inside the insertion hole 404.
[0049] It should be noted that the mounting hole 402 is adapted to the inner insert 401. The inner insert 401 is inserted into the interior of the mounting hole 402. The top of the inner insert 401 is adapted to the bottom of the product to be molded. The cylinder 405 is an existing device for moving objects. When demolding is required, the top mold 3 is first moved away from the bottom mold 2. Then the cylinder 405 is opened, and the cylinder 405 drives the push rod 403 and the inner insert 401 to move. The inner insert 401 then moves the product out of the molding cavity at the top of the bottom mold 2, thereby assisting in demolding.
[0050] Specifically, mobile component 5 includes:
[0051] Horizontal bar 503 is set on one side of bottom mold 2;
[0052] Baffle 504 is fixedly connected to one end of crossbar 503;
[0053] Connection hole 501 is provided on one side of baffle 504;
[0054] Through hole 502 is provided at the top of baffle 504.
[0055] Specifically, the bottom end of the crossbar 503 is fixedly connected to the upright 505, the bottom end of the platform 1 is fixedly connected to the motor 506, the upright 505 is fixedly connected to the output end of the motor 506, and a limiting member 6 is provided at the connection between the platform 1 and the upright 505.
[0056] It should be noted that the motor 506 is an existing servo motor, which is used to drive the upright 505 at its output end to rotate during use. The crossbar 503 is used to connect the upright 505 and the baffle 504. The connecting hole 501 is opened on one side of the baffle 504, and the connecting hole 501 is used to push the rod 403 into the interior of the through hole 502. The through hole 502 is adapted to the inner insert 401, so that the inner insert 401 can pass through the through hole 502 and pass through the baffle 504.
[0057] Furthermore, when the product is pushed out of the molding cavity by the push rod 403 and the insert 401, the motor 506 drives the upright rod 505 to rotate, and the upright rod 505 drives the cross rod 503 and the baffle 504 to rotate. The push rod 403 moves into the through hole 502 through the connecting hole 501, and then the cylinder 405 drives the push rod 403 and the insert 401 to move out of the through hole 502. The baffle 504 blocks the product, so that the product is located on the top of the baffle 504. Then the motor 506 drives the baffle 504 to rotate and reset the baffle 504.
[0058] Example 2:
[0059] Restricting component 6 is used in the injection molding structure of Example 1;
[0060] Specifically, the limiting component 6 includes a fixing block 601 fixedly connected to the top of the tabletop 1. A through hole 603 is provided in the middle of the fixing block 601, and the upright 505 is inserted into the inside of the through hole 603.
[0061] Specifically, a limiting groove 602 is provided on the inner wall of one side of the through hole 603, and a limiting block 604 is fixedly connected to the bottom of the upright 505. The limiting block 604 is inserted into the inside of the limiting groove 602.
[0062] It should be noted that the fixed block 601 is fixedly connected to the table surface 1. The through hole 603 in the middle is adapted to the upright 505, so that the upright 505 can be inserted into the through hole 603. The through hole 603 and the upright 505 are cylindrical, so that the upright 505 can rotate on the fixed block 601 through the through hole 603. The limiting groove 602 is fan-shaped. When the upright 505 rotates, it drives the limiting block 604 at the bottom of the upright 505 to rotate. When the limiting block 604 rotates to fit against the side wall of the limiting groove 602, the limiting groove 602 restricts the limiting block 604, and the limiting block 604 restricts the rotation angle of the upright 505.
[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
