Technical Field

[0001] The utility model relates to the technical field of fiberglass production, in particular to an auxiliary demoulding device for fiberglass products. Background Technique

[0002] Fiberglass products are products processed from fiberglass as raw materials, which have many advantages such as light weight, high strength, corrosion resistance, heat preservation, insulation, sound insulation, and long service life. When producing fiberglass products with a mold, after the fiberglass products are cooled, they are demoulded and removed from the mold.

[0003] However, it still has the following disadvantages in actual use:

[0004] Since the product fits closely with the four sides of the mold, when directly demoulding, it may cause uneven local stress on the surface of the product, easily resulting in surface deformation, damage or scratches, affecting the appearance quality of the product.

[0005] Therefore, a new auxiliary demoulding device for fiberglass products is proposed to solve the above problems. Content of the Utility Model

[0036] The lower mold 12 and the cavity 13 are used to form the product shape and play a role in support and positioning;

[0037] The auxiliary demolding component, which includes an annular groove 26 opened in four circles on the inner bottom surface of the cavity 13, a first circular through hole 27 opened at the four corners of the inner bottom surface of the annular groove 26, an annular support plate 25 movably connected in the annular groove 26, a second electric push rod 24 movably connected in the first circular through hole 27, a circular groove 28 opened in the middle of the inner bottom surface of the cavity 13, a second circular through hole 29 opened in the middle of the inner bottom surface of the circular groove 28, a circular support plate 23 movably connected in the circular groove 28, a support column 22 movably connected in the second circular through hole 29, a support plate 21 connected to the lower part of the support column 22 by screws, and a first electric push rod 20 connected to the lower part of the support plate 21 by screws;

[0038] The first electric push rod 20 and the second electric push rod 24 realize position adjustment. The support plate 21, the support column 22, the annular support plate 25 and the circular support plate 23 play a supporting role. The first circular through hole 27 and the second circular through hole 29 provide a moving space and play a limiting role at the same time. The annular groove 26 and the circular groove 28 are used to accommodate the annular support plate 25 and the circular support plate 23;

[0039] There are four groups of the first electric push rods 20, which are symmetrically distributed at the four corners under the support plate 21;

[0040] Setting four groups of the first electric push rods 20 makes the movement of the support plate 21 more stable;

[0041] There are four groups of the second electric push rods 24, which are connected to the four corners above the support plate 21 by screws;

[0042] Setting four groups of the second electric push rods 24 makes the movement of the annular support plate 25 more stable;

[0043] The main body component further includes a support base 11 connected to the lower part of the lower mold 12 by screws and a base 10 connected to the lower part of the support base 11 by screws;

[0044] The support base 11 and the base 10 play a supporting role. At the same time, the support base 11 forms a certain space under the lower mold 12;

[0045] The main body component further includes a water circulation interface 14 connected to the side of the lower mold 12 by screws, and the water circulation interface 14 is connected to the internal cooling water pipe of the lower mold 12;

[0046] The water circulation interface 14 is used to connect the water circuit;

[0047] The lower end of the first electric push rod 20 is connected to the upper surface of the base 10 by screws, and the first electric push rod 20 is located inside the support seat 11.

[0048] Working principle:

[0049] Before the product production starts, the first electric push rod 20 and the second electric push rod 24 contract, so that the annular support plate 25 and the circular support plate 23 are respectively located in the annular groove 26 and the circular groove 28.

[0050] After the product is formed in the cavity 13 of the lower mold 12, cooling water is introduced through the water circulation interface 14, and the product is cooled and formed.

[0051] At this time, the second electric push rod 24 is started. The second electric push rod 24 slightly extends along the first circular through hole 27, driving the annular support plate 25 to move slightly upward, so that the four sides of the product in contact with the lower mold 12 are separated, and then the second electric push rod 24 contracts.

[0052] At this time, the first electric push rod 20 is started. The first electric push rod 20 extends, driving the support plate 21 to move upward, driving the support column 22 to move upward along the second circular through hole 29, and at the same time driving the second electric push rod 24 to move upward as a whole.

[0053] At this time, the annular support plate 25 and the circular support plate 23 move upward to separate from the annular groove 26 and the circular groove 28, and the product is separated from the lower mold 12.

[0054] This step can avoid damage and deformation of the four sides of the product. Embodiment 2

[0055] Please refer to Figure 5 As shown, on the basis of the above Embodiment 1, this embodiment further includes:

[0056] An anti-damage component, which includes a square through hole 30 opened on the inner bottom surface of the annular groove 26 and a grid hole 31 opened on the inner bottom surface of the circular groove 28;

[0058] There are four groups of square through holes 30, which are distributed on the four sides of the annular groove 26.

[0059] Working principle:

[0060] When the product is demolded, some debris and burrs will fall into the lower mold 12. The lower mold 12 can be purged by a dust removal device, and the debris and burrs will fall from the square through hole 30 and the grid hole 31.

[0061] This step is beneficial to removing the debris and burrs in the lower mold 12.
