Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a demoulding and feeding device. Background Art

[0002] A mold is a tool used to make molded objects. This tool is made up of various parts, and different molds are made up of different parts. A mold is generally made up of a concave mold and a convex mold.

[0003] In the prior art, when the mold is in use, it is generally a combination of a concave mold and a convex mold. After the injection molding is completed, the concave mold and the convex mold are separated, and then the product formed inside is demolded manually. After the demolding is completed, it is transported to the next process to perform operations such as grinding on its corners and residues.

When the trapezoidal block 5 moves upward inside the sliding slot 4, it can drive the T-shaped plate 3 to move upward inside the T-shaped slot 2, thereby pushing the product inside the die 1 to move upward, so that the product inside the die 1 is separated from the inside of the die 1, and the demoulding operation is completed.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In one aspect of this embodiment, an ejector assembly is provided on one side of the die 1, and the ejector assembly is used to push the trapezoidal block 5 to move upward;

Through the cooperation between the roller 7 and the inclined surface at the bottom of the trapezoidal block 5, the trapezoidal block 5 can be pushed to move upward inside the sliding groove 4, thereby better completing the ejection and demoulding operation.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In one aspect of this embodiment, a pushing assembly is provided on the top of the ejection assembly, and the pushing assembly is used to push the feeding;

[0034] The pushing assembly includes a fixed plate 8, two slide bars 9, a pushing plate 10, a connecting plate 11 and two springs 12.

The product pushed over is unloaded by the sloping plate 17, so that it slides and falls onto the conveyor belt, and then the feeding operation is completed.

[0036] Working principle:

[0037] When in use, firstly, the cylinder 16 is controlled by an external control device to work, driving the punch 15 to move upward under the action of the four fixing rods 13, so that the punch 15 and the die 1 are closed, and then the injection molding operation can be carried out;

[0038] After the injection molding is completed, the cylinder 16 controls the convex mold 15 to separate from the concave mold 1, and then the operator pushes the U-shaped plate 6 to move, which can drive the roller 7 located on the top thereof to move. Through the cooperation between the roller 7 and the bottom inclined surface of the trapezoidal block 5, the trapezoidal block 5 can be pushed to move upward inside the sliding groove 4, so as to better complete the ejection and demoulding operation;

[0039] When the trapezoidal block 5 moves upward inside the sliding groove 4, it can drive the T-shaped plate 3 to move upward inside the T-shaped groove 2, so that it pushes the product inside the die 1 to move upward, so that the product inside the die 1 is separated from the inside of the die 1, thereby completing the demoulding operation;

[0040] Then, the connecting plate 11 is pushed to move toward the die 1, driving the two slide bars 9 to move, and at the same time, the fixing plate 8 and the connecting plate 11 are used to squeeze the spring 12, and drive the pushing plate 10 to move, and the pushing plate 10 is used to push and feed the product ejected by the ejection assembly;

[0041] The pushed product enters the top of the inclined plate 17 and slides down under the action of gravity, so that it slides and falls onto the conveyor belt, and then the feeding operation is completed.

[0042] By setting up the ejection component, the trapezoidal block 5 can be used to quickly demold the product after injection molding, without the need for manual insertion into the mold for demolding. At the same time, by setting up the pushing component, after the demolding operation is completed, the pushing and feeding operation can be carried out continuously, so that it can quickly enter the next process for processing. This not only reduces the labor workload of workers, but also improves production efficiency, which is beneficial to practical application and operation.
