DETAILED DESCRIPTION

[0039] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0040] As a specific embodiment, the continuous injection mold of the embodiment of the present invention includes an injection molding machine template 9 and an injection mold 1 installed on the injection molding machine template 9 .

[0041] As a prior art, the injection mold 1 includes a movable mold 11 and a fixed fixed mold 12, and the movable mold 11 can move relative to the fixed mold 12; after the movable mold 11 and the fixed mold 12 clamp the injection molding net W1 and simultaneously close the mold to form a mold cavity (not marked in the accompanying drawings), plastic is injected into the mold cavity through the movable mold 11 or the fixed mold 12 to form an injection molded workpiece W2 containing the injection molding net W1 (for example, the injection molded workpiece W2 is an air filter net in an air conditioner); at this time, adjacent injection molded workpieces W2 are still connected by the injection molding net W1; thereby, a continuous injection molding net W1 and injection molded workpiece W2 can be formed through the injection mold 1.

[0042] The output device 2 is also provided at the output end of the injection mold 1, and the output device 2 includes a collecting device 23 and an output support frame 21 higher than the top surface of the collecting device 23. Generally, the collecting device 23 can be a box or other device for collecting the continuous injection molding web W1 and the injection molding workpiece W2.

[0043] The working principle is that before use, the injection mold 1 is first used to perform several injection moldings until the continuous injection molding net W1 and the injection molding workpiece W2 formed can extend from the output support frame 21 and hang down (usually the preparation work is completed manually), and the preparation is completed.

[0044] The weight of the continuous injection molding net W1 and the injection molding workpiece W2 extending from the output support frame 21 causes the injection molding net W1 to move, and the reciprocating motion of the movable mold 11 relative to the fixed mold 12 realizes continuous injection molding, which can improve production efficiency and product quality; at the same time, since human hands do not need to pass between the movable mold 11 and the fixed mold 12, safety can be ensured. Usually, the continuous injection molding net W1 and the injection molding workpiece W2 need to be cut separately to form a single injection molding workpiece W2 containing the injection molding net W1.

[0045] Furthermore, the injection mold 1 includes a movable mold 11 and a fixed mold 12, and the mold surface of the fixed mold 12 is substantially horizontal or vertically arranged; an offset distance 211 is arranged between the output support frame 21 and the fixed mold 12. The continuous injection molding net W1 and the injection molding workpiece W2 between the output support frame 21 and the fixed mold 12 are tilted and suspended in the air, which can reduce friction and ensure that the continuous injection molding net W1 and the injection molding workpiece W2 are smoothly output.

[0046] Preferably, the output support frame 21 is fixedly provided with a mounting plate 212, and the mounting plate 212 can be moved up and down relative to the fixed mold 12 and maintained. It is convenient to adjust the offset distance 211 accordingly according to the weight and size of the injection molded workpiece W2. As an embodiment, the mounting plate 212 is provided with a height adjustment hole 213 which is a long hole, and a bolt (not shown in the drawings) passes through the height adjustment hole 213 and is threadedly connected to the fixed mold 12. After loosening the bolt, the mounting plate 212 is moved up and down and then tightened to achieve the adjustment of the offset distance 211.

[0047] Furthermore, the output device 2 further includes an output push block 22 and a driving member 221, wherein the driving member 221 is disposed on the output support frame 21 and drives the output push block 22 to reciprocate approximately along the output support frame 21. During the movement of the output push block 22 in the output direction, the continuous injection molding net W1 and the injection molding workpiece W2 between the output support frame 21 and the fixed mold 12 are moved in the output direction by means of friction or the holding force between the injection molding workpiece W2; during the resetting of the output push block 22 (in the direction opposite to the output direction), since the continuous injection molding net W1 and the injection molding workpiece W2 between the output support frame 21 and the fixed mold 12 are tilted and suspended in the air, the output push block 22 will not interfere with the continuous injection molding net W1 and the injection molding workpiece W2 between the output support frame 21 and the fixed mold 12; that is, it can ensure that the continuous injection molding net W1 and the injection molding workpiece W2 between the output support frame 21 and the fixed mold 12 are smoothly output from the output support frame 21.

[0048] As an implementation mode, the output device 2 further includes a synchronous wheel 222 and a servo motor 223 that drives the synchronous wheel 222 to rotate (it can be driven by a transmission member such as a belt or a chain, and the transmission member between the synchronous wheel 222 and the servo motor 223 is not shown), and the driving member 221 is a synchronous belt fixedly connected to the output push block 22, and the output push block 22 is sleeved on the synchronous wheel 222. The servo motor 223 drives the synchronous wheel 222 to reciprocate, and drives the driving member 221 and the output push block 22 to reciprocate.

[0049] Preferably, the servo motor 223 is fixed directly below the output device 2. The overall width of the output device 2 can be reduced.

[0050] Furthermore, an electric control device (not shown in the drawings) is also included, and the servo motor 223 and the injection mold 1 are electrically connected to the electric control device respectively. The electric control device usually includes a conventional PLC controller, a servo driver, etc., which can match the movement frequency of the output push block 22 with the injection frequency of the injection mold 1. For example, when the injection mold 1 is injected once, the output push block 22 reciprocates once, ensuring stable production.

[0051] Furthermore, the injection mold 1 includes an input device 3 disposed on the input side of the injection mold 1, and the input device 3 includes a rotatable input wheel 31. The input wheel 31 may be a driven wheel without power, or may have rotational power (for example, through a servo motor drive, etc.). The rolled injection molding net W1 can be put on the input wheel 31 for easy production.

[0052] Preferably, the input device 3 further comprises an adjustment roller 32 arranged at the input side of the injection mold 1. The height of the injection molding web W1 input to the injection mold 1 can be adjusted, which is beneficial to ensure the quality.

[0053] As another embodiment, the mating surface of the fixed mold 12 is substantially vertically arranged. Generally, in this embodiment, the adjustment roller 32 can be a driven wheel, which can further reduce the cost.

[0054] The terms first, second, etc. used in the present invention do not indicate any order, quantity or importance, but are only used for distinction.

[0055] As used herein, the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced object.

[0056] Terms indicating orientation or position as used in the present invention, such as top, bottom, side, longitudinal, lateral, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0057] As used in the present invention, the terms: generally, overall, approximately, close, etc., are limiting terms to indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of the size includes but is not limited to the national standard of the size tolerance.
