Description

Technical Field

[0001] The present application relates to the field of foam machine design, and more particularly, to a demoulding device for a foam molding machine. Background Art

[0002] After the plastic in the mold is cooled and formed, the foam machine opens the mold. The finished product usually adheres to the mold, and at this time, the ejector rod is required to push the finished product off the mold. Considering that after the foam machine is used multiple times, residual plastic particles will inevitably adhere to the machine. The common ejector rod support plate for installing the ejector rod usually protrudes some pins on the plane facing the mold, so that when the ejector rod support plate moves towards the mold to the farthest, the pins abut against the mold, avoiding the flat ejector rod support plate directly contacting the mold. Thus, it prevents the ejector rod support plate from pressing on the uneven plastic particles, causing the ejector rod support plate to bend, resulting in the ejector rod installed on the ejector rod support plate being unable to align with the holes reserved on the mold.

[0003] The disadvantage of this structure is that after the pins are installed on the ejector rod support plate, the movement range of the ejector rod support plate is controlled by the pins. If adjustment is required, pins of different lengths need to be replaced, and the operation is cumbersome. Installing the pins also increases the weight of the ejector rod support plate, increasing the burden on the power component driving the ejector rod support plate and reducing its service life.

[0026] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] Refer to Figures 1-3 ,

[0028] A demoulding device for a foam molding machine, comprising: a foam molding machine body 1, a thimble 3 support 2, a thimble 3, and a power member 4. The foam molding machine body 1 is a selected existing product with functions of opening and closing a mold and injecting into the mold. A mold support 11 is integrated in the foam molding machine body 1, and the mold is fixed to the mold support 11 by bolts. Multiple groups of thimbles 3 are provided. One end of multiple groups of thimbles 3 points to the mold support 11, and the other end is fixedly connected to the thimble 3 support 2. The power member 4 is a cylinder. The power member 4 is disposed between the mold support 11 and the thimble 3 support 2. The fixed end of the power member 4 is fixedly connected to one side of the mold support 11 facing the thimble 3 support 2 by bolts, and the output end of the power member 4 is fixedly connected to one side of the thimble 3 support 2 facing the mold support 11 by bolts. The output end of the power member 4 extends to move the thimble 3 support 2 away from the mold support 11. The output end of the power member 4 retracts to move the thimble 3 support 2 closer to the mold support 11, so that the thimble 3 support 2 drives the thimble 3 to push the finished product off the mold. When the output end of the power member 4 retracts to drive the thimble 3 support 2 closer to the mold support 11, the closest distance between the mold support 11 and the thimble 3 support 2 is equal to the length of the fixed end of the power member 4 plus the length of the extended output end. According to the thickness of different molds, the minimum length of the extended output end of the power member 4 can be adjusted between 5 - 10 cm.

[0029] Specifically, the mold support 11 includes: a first frame 111 and rib plates 112. Multiple groups of rib plates 112 are provided in the first frame 111, specifically four groups. The four groups of rib plates 112 are arranged side by side horizontally in the first frame 111. The ends of the four groups of rib plates 112 are welded and fixed to the inner wall of the first frame 111. Five gaps are formed between adjacent rib plates 112 and between the rib plates 112 and the first frame 111. Multiple thimbles 3 are provided, and the multiple thimbles 3 are evenly distributed in the five gaps. The gaps serve as a clearance for the movement of the thimbles 3. At the same time, the combination of the first frame 111 and the four groups of rib plates 112 makes the overall weight of the mold support 11 lighter than that of a common solid flat plate support.

[0030] Specifically, the foam molding machine body 1 further includes: a frame 12 and guide rods 13. Four groups of guide rods 13 are provided. The ends of the four groups of guide rods 13 are fixedly connected to the frame 12 by bolts. The middle parts of the four groups of guide rods 13 pass through the four corners of the thimble 3 support 2 and are in sliding fit with the thimble 3 support 2. The four groups of guide rods 13 play a role in guiding and supporting the movement of the thimble 3 support 2.

[0031] Specifically, the thimble 3 support 2 includes: a second frame 21 and a grid plate 22. The ends of the thimbles 3 are fixed to the grid plate 22. The grid plate 22 is disposed in the second frame 21. The grid plate 22 is detachably connected to the inner wall of the second frame 21 by screws. The four corners of the second frame 21 are in sliding connection with the guide rods 13. According to the specifications of different molds, the grid plate 22 and the thimbles 3 can be replaced as a whole, improving production efficiency.

[0032] Specifically, the frame 12 includes a first limiting plate 121 and a second limiting plate 122. The first limiting plate 121 is disposed on the side of the second frame 21 facing away from the mold support 11, and the second limiting plate 122 is disposed on the side of the second frame 21 facing the mold support 11. When the power member 4 moves the second frame 21 away from the mold support 11, the second frame 21 moves at most until it abuts against the first limiting plate 121. When the power member 4 moves the second frame 21 closer to the mold support 11, the second frame 21 moves at most until it abuts against the second limiting plate 122. The first limiting plate 121 and the second limiting plate 122 cooperate to limit the movement range of the ejector rod 3 support 2.

[0033] Specifically, threaded holes are formed on the grille plate 22 facing the mold support 11, and an external threaded portion is formed at one end of the ejector rod 3. The external threaded portion is threadedly connected to the threaded holes. When the ejector rod 3 needs to be replaced, the worker only needs to unscrew the old ejector rod 3 from the grille plate 22, and then align the external threaded portion of the new ejector rod 3 with the threaded holes and screw it in.

[0034] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
