In the scheme, through the L1 > L2 on two first curb plates, make first curb plate be the structure that the slope set up, form the drawing of patterns angle from this, be convenient for smooth drawing of patterns can solve the problem that current drawing of patterns frock exists.

Preferably, a plurality of rib outlet grooves are arranged on the first side plate and the second side plate, the rib outlet grooves vertically penetrate downwards, and the rib outlet grooves are communicated with the cavity.

Preferably, the rib outlet groove is a rectangular groove, and the width of the rib outlet groove on the second side plate is larger than that of the rib outlet groove on the first side plate.

Preferably, the handle extends along the length of the first side plate.

Preferably, the pre-reserved hole demolding tool further comprises a plurality of rib plates, and the rib plates are connected with the top plate and the second side plate in the cavity.

Preferably, the rib plate is triangular, and at least two rib plates are arranged on the second side plate.

Preferably, one of the two second side plates is inclined from the top plate toward the cavity.

Compared with the related art, the utility model has the beneficial effects that

1. The reserved hole demoulding tool is provided with an inclined demoulding angle, so that demoulding is easy, and edge-missing and corner-falling of a floor slab or a wallboard are avoided;

2. the foam processing machine has the advantages of reducing working hours required by foam processing in each round, improving production efficiency, reducing environmental pollution, reducing material cost, smoothly demoulding without edge and corner drop during demoulding, and improving the appearance quality of floor wallboard finished products.

Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 1-3, the reserved hole demolding tool provided in this embodiment includes a top plate 1, a first side plate 2, a second side plate 3, a cavity 4, a handle 5, a rib outlet groove 6 and a rib plate 7.

The first side plates 2 are arranged at intervals, the second side plates 3 are connected with the first side plates 2 at two ends of the first side plates 2, and the first side plates 2 and the second side plates 3 are surrounded and formed with a cavity 4. The bottom of the cavity 4 is communicated, and the top of the cavity 4 covers the top plate 1. The demolding tool with the cavity 4 can lighten the weight of the demolding tool, and is convenient to take and use.

In order to facilitate demolding, a distance L1 is formed at one end of the two first side plates 2 connected with the top plate 1, a distance L2 is formed at the other end of the two first side plates 2, and L1 > L2, thereby forming the first side plates 2 into a demolding angle inclined from the top plate 1 to the cavity 4 direction. The demolding angles of the first side plates 2 at the two ends can be the same or different according to actual needs. And the handle 5 is arranged on the top plate 1, and the handle 5 extends along the length direction of the first side plate 2, so that better stress can be realized.
