Problems solved by technology

When the production scale of concrete prefabricated parts is large, the manufacturer will specially design and develop special molds, but such molds usually have a single specification, and only one mold can be used to produce one kind of concrete prefabricated parts.
Whether it is temporary modeling or designing a special mold, there are problems such as time-consuming and laborious, high production cost and low versatility, and after one pouring is completed, the process of cleaning the table is also troublesome
[0003] CN204525721U has announced a kind of fixture and prefabricated part mold for side mold, comprise fixed plate, clamp body and magnetic box, fixed plate is used for detachably fixedly connected with side mold, and clamp body can be connected with described fixed plate by fixing piece The detachable fixed connection, the magnetic box is detachably fixed on the fixture body, although this utility model can adjust the position of the fixture body according to the different specifications and sizes of the prefabricated parts, so that it can be fixed at different positions of the side mold, thus forming different sizes The mold can realize the production of concrete precast parts of different sizes with one set of molds, and there is no need to equip a set of molds for each concrete precast part, which has the advantages of saving time, labor and low production cost, but the fixing of the utility model side mold The process of dismantling and formwork is cumbersome, and the positioning is inconvenient, which will prolong the assembly time, and because the fixing of the side formwork uses more bolt structures, it is easy to loosen after repeated use, so that the fixing effect of the side formwork is great. discounted, resulting in a reduced service life of the utility model

Embodiment 1

[0028] as attached figure 1 , attached figure 2 Shown: a quick mold change device for flat molds of prefabricated components, including a reference rib 2 and three positioning ribs 3 located on a magnetic trolley 1, the reference rib 2 and three positioning ribs 3 form a closed Plane, according to the length, width and height of the required prefabricated components, select the appropriate length and height of the positioning rib 3 and the intercepted reference rib 2 of appropriate length to form a closed plane. The height and length of the reference rib 2 are generally reserved , which is convenient for the universality of the reference rib 2, and the prefabricated components that meet the requirements can be obtained by pouring concrete in this airtight plane; in the actual operation process, an additional layer can be added between the positioning rib 3 and the trolley 1 The water retaining strip is used to increase the sealing between the positioning rib 3 and the trolle...

Embodiment 2

[0035] as attached image 3 , attached Figure 4 Shown: a quick mold change device for flat molds of prefabricated components, including a reference rib 2 and six positioning ribs 3 on the magnetic trolley 1, the reference rib 2 and the positioning ribs 3 can form two airtight Plane, two planes share a reference rib 2, intercept the length of the required reference rib 2 according to the needs, and pour concrete into the two enclosed planes at the same time, and two same or different prefabricated components can be carried out at the same time Preparation, the reference rib 2 is installed on the edge of the upper surface of the trolley 1 by welding to ensure that the position stability of the reference rib 2 on the trolley 1 is high, and the outer surface of the reference rib 2 is provided with a scale ( Not shown in the figure), it is convenient to quickly intercept a certain length of the reference rib 2, and it is also convenient to quickly find the connection point betwee...

Embodiment 3

[0040] as attached image 3 , attached Figure 5 Shown: the difference between the pressing plate in this embodiment and embodiment 2 is that: the number of pressing mechanisms 8 on the first support part of each pressing plate 4 is two, and the locks of the pressure rods 9 in the two pressing mechanisms 8 The tightening direction is opposite, so that when receiving a force in one direction, at least one pressure bar 9 is not affected by external force, which is beneficial to improve the stability of the formwork. This approach can effectively save the consumption of the magnetic box 5 while increasing the number of pressing points to ensure the stability of the positioning rib 3, which is beneficial to saving production costs.

Abstract

The invention relates to a quick die replacing device for a prefabricated member flat die. The quick die replacing device comprises a standard stopping edge fixedly arranged on a magnetic trolley face, a plurality of positioning stopping edges movably connected with the magnetic trolley face and a compression assembly used for fixing the positioning stopping edges; and a flat die structure is defined by the standard stopping edge and the positioning stopping edges, the compression assembly comprises a pressing plate and a magnetic box, one end of the pressing plate is pressed to the positioning stopping edges, and the other end of the pressing plate is fixed through the magnetic box. By means of the quick die replacing device for the prefabricated member flat die, the die replacing time can be greatly shortened, the universality is high, the production cost is better reduced, and the production efficiency is improved; in addition, the fixing reliability of the stopping edges is higher, displacement is not likely to occur, the service life is longer, and the fixing performance degradation of the quick die replacing device is less after repeated use.

Description

technical field [0001] The invention relates to building material production equipment, in particular to a quick mold changing device for flat molds of prefabricated components. Background technique [0002] Currently widely used concrete prefabricated parts, including floor slabs, wall slabs, etc., when the production scale of concrete prefabricated parts is small, usually no special mold is designed. The ribs are fixed and poured by various non-standard simple fixtures. When the production scale of concrete prefabricated parts is large, the manufacturer will specially design and develop special molds, but such molds usually have a single specification, and only one mold can be used to produce one kind of concrete prefabricated parts. Whether it is temporary modeling or designing a special mold, there are problems such as time-consuming and laborious, high production cost and low versatility, and the process of cleaning the table after one pour is completed is also trouble...
