Description

Technical Field

[0001] This utility model belongs to the technical field of slab production equipment, and in particular relates to a multi-directional pressure mold for dry pressing of slab blanks. Background Technology

[0002] The production of slab blanks is a rigorous and complex process involving multiple key steps, including raw material preparation, batching, ball milling, slurry storage, spray tower powder making, press forming, brick blank drying, glazing, 3D inkjet printing, kiln firing, cooling, and polishing. During the press forming process, the powder needs to be put into the mold and pressure is applied to make it into a dense blank. It has the advantages of high production efficiency, low scrap rate, and short production cycle.

[0003] A search revealed CN219027915U, with an application date of November 29, 2022, which discloses an integrated molding mold for sintered stone slabs. The mold includes a base plate mounted on the sintered stone slab forming station. Connecting cylinders are located at the four corners of the top of the base plate, and a top plate is located on top of each connecting cylinder. A demolding assembly is located between the connecting cylinders on the top of the base plate, facilitating rapid demolding. This design is suitable for rapid demolding of the integrated molding mold for sintered stone slabs during the sintered stone slab production process. The top plate is connected to the connecting cylinders on the base plate via a rod, creating a sealed seal between the sealing cap and the mold shell. Sintered stone slab material is then injected into the mold shell through an injection port. The material undergoes molding within the mold body. After injection molding, the operator removes the top plate and activates a hydraulic telescopic rod to slide the lower movable plate upwards, causing the demolding assembly to move upwards and extrude the sintered stone slab from the mold body, thus achieving rapid demolding and improving demolding efficiency.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. In the existing multi-directional pressure mold for dry pressing of slab blanks, a large amount of powder will be scattered on the surface of the mold base after the slab blank is pressed and formed, which will affect the cleanliness of the production equipment surface and cause powder waste.

[0006] 2. Existing multi-directional pressure molds for dry pressing of sintered stone blanks cause a large amount of powder to scatter on the equipment surface, resulting in a significant amount of dust being emitted into the working environment and affecting the health of production personnel. Therefore, we provide a multi-directional pressure mold for dry pressing of sintered stone blanks to solve the above-mentioned problems. Utility Model Content

By setting a pushing component, the formed slab blank and excess powder are pushed out. The dust will fall into the collection box along the guide plate, which can clean the dust on the surface of the mold base, ensure the cleanliness of the production equipment surface, and avoid powder waste. At the same time, the dust collection component can be used to suck the flying dust generated by the powder falling part of the guide plate into the dust box, so as to avoid a large amount of dust flying in the working environment and affecting the health of production personnel.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A hydraulic device is provided on the top of the guide rods. A mold seat is installed at the center of the upper surface of the base. A lifting side mold is provided on the outside of the mold seat. A lifting pressure seat is slidably installed on the outer wall of the guide rods. A pushing component is provided on the rear end face of the lifting side mold. A dust collection component is provided on one side of the upper surface of the base.

[0010] The pushing assembly includes a mounting plate that is bolted to the rear end face of the lifting side mold, and a cylinder mounted on the upper surface of the mounting plate. A push plate is mounted on the telescopic end of the cylinder, and a first air pipe is provided on the outer wall of the cylinder.

[0011] The dust collection assembly includes a dust box mounted on the upper surface of the base, and a second sealing plug movably mounted inside the dust box, with a piston rod disposed in the middle of the upper surface of the second sealing plug.

[0012] The present invention is further configured such that a conveying device is provided at the upper front end of the base, a guide plate is installed at an angle on the front end face of the base, and a collection box is placed in front of the base.

[0013] The present invention is further configured such that the other end of the second connecting pipe is connected to the second air pipe through a pipe joint, the other end of the second air pipe is located at the bottom of the outer wall of the air cylinder, and the air cylinder is installed on the outer wall of the mounting plate by bolts and fixing rings.

[0014] The present invention is further configured such that a first sealing plug is movably installed inside the air cylinder, and a first toothed plate is provided at the top center of the first sealing plug, with the top of the first toothed plate penetrating through the top of the air cylinder.

[0015] The present invention is further configured such that a toothed disc is engaged with the front of the first toothed plate, the toothed disc is rotatably mounted inside the bracket, and the bottom of the bracket is mounted on the surface of the air cylinder by bolts.

[0016] The present invention is further configured such that a second toothed plate is engaged with the front of the toothed disc, a connecting rod is fixedly provided on the top of the front end face of the second toothed plate, and the other end of the connecting rod is fixedly provided on the rear end face of the lifting pressure seat.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a pushing component and adjusting the height of the lifting pressure seat, allows the gas in the air cylinder and air pump to circulate back and forth under the combined action of the first toothed plate, the second toothed plate, and the toothed disc. This enables the pushing plate to move back and forth, pushing out the formed slab blank and excess powder. The dust will fall into the collection box along the guide plate, cleaning the dust on the surface of the mold seat and ensuring the cleanliness of the production equipment. At the same time, it can avoid powder waste. This solves the problem that in the existing multi-directional pressure mold for dry pressing of slab blanks, a large amount of powder will be scattered on the surface of the mold seat after the slab blank is pressed, which will affect the cleanliness of the production equipment and cause powder waste.

[0021] 2. This utility model, by setting up a dust collection component, allows the height adjustment of the lifting pressure seat to drive the second sealing plug to move up and down, creating a negative pressure inside the dust box. This draws the flying dust generated by the falling powder from the guide plate into the dust box, preventing a large amount of dust from flying in the working environment and affecting the health of production personnel. This solves the problem of existing multi-directional pressure molds for dry pressing of slab blanks causing a large amount of powder to scatter on the equipment surface, resulting in a large amount of dust flying in the working environment and affecting the health of production personnel.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1 to 4This utility model is a multi-directional pressure mold for dry pressing of rock slab blanks, including a base 100 and guide rods 101 installed at four corners on its surface. A hydraulic device 102 is provided on the top of the guide rods 101. A mold seat 103 is installed at the center of the upper surface of the base 100. A lifting side mold 104 is provided on the outer side of the mold seat 103. A lifting pressure seat 105 is slidably installed on the outer wall of the guide rods 101. A pusher assembly 200 is provided on the rear end face of the lifting side mold 104. The pusher assembly 200 includes a mounting plate 201 installed on the rear end face of the lifting side mold 104 by bolts, and a cylinder 202 installed on the upper surface of the mounting plate 201. A pusher plate 203 is installed on the telescopic end of the cylinder 202. A first air pipe 202a is provided on the outer wall of the cylinder 202. The other end of the first air pipe 202a is connected to a second connecting pipe 303 through a pipe joint.

[0034] Specifically, a conveying device 106 is provided at the upper front end of the base 100, a guide plate 107 is installed at an angle on the front face of the base 100, and a collection box 108 is placed in front of the base 100; the other end of the second connecting pipe 303 is connected to the second air pipe 204a through a pipe joint, and the other end of the second air pipe 204a is located at the bottom of the outer wall of the air cylinder 204. The air cylinder 204 is installed on the outer wall of the mounting plate 201 by bolts and fixing rings; a first sealing plug 204b is movably installed inside the air cylinder 204. A first toothed plate 204c is provided at the top center position, and the top of the first toothed plate 204c penetrates the top of the air cylinder 204; a toothed disc 205 is meshed and connected to the front of the first toothed plate 204c, and the toothed disc 205 is rotatably installed inside the bracket 205a. The bottom of the bracket 205a is installed on the surface of the air cylinder 204 by bolts; a second toothed plate 206 is meshed and connected to the front of the toothed disc 205, and a connecting rod 206a is fixedly provided on the top of the front end face of the second toothed plate 206. The other end of the connecting rod 206a is fixedly provided on the rear end face of the lifting pressure seat 105.

[0035] Furthermore, the base 100, guide rod 101, hydraulic equipment 102, mold base 103, lifting side mold 104, etc. are all existing technologies, so they will not be described in detail here. The gas flow in the cylinder 202 and the air cylinder 204 is connected. The pipe joint serves as a pipe connection. The bottom of the push plate 203 is made of flexible material to avoid damage to the surface of the mold base 103 and the lifting side mold 104 when the push plate 203 pushes the material. The collection box 108 is used for collecting powder. The first toothed plate 204c and the toothed disc 205 mesh, and at the same time, the second toothed plate 206 meshes with the toothed disc 205 to form a linkage mechanism. The first toothed plate 204c moves up and down, and the second toothed plate 206 moves in the opposite direction under the action of the toothed disc 205.

[0036] The operation process of this embodiment is as follows: When producing the slab blank, the powder for production is put into the mold base 103. Then, the hydraulic equipment 102 is started to push the lifting pressure seat 105 downward. The downward movement of the lifting pressure seat 105 will cooperate with the lifting side mold 104 to squeeze the dry powder in the mold base 103, so that the dry powder forms the slab blank under high pressure. After the slab blank is integrally pressed and formed, the lifting pressure seat 105 is raised by the hydraulic equipment 102, and the lifting side mold 104 is lowered. At this time, the upward movement of the lifting pressure seat 105 will drive the second toothed plate 206 to move upward through the connecting rod 206a. The rack on the outer wall of the second toothed plate 206 meshes with the rack on the toothed disc 205. At the same time, the rack on the outer wall of the toothed disc 205 also meshes with the rack on the rear first toothed plate 204c. Therefore, when the second toothed plate 206 moves upward, it will... The toothed disc 205 causes the first toothed plate 204c to descend, which in turn pushes the first sealing plug 204b downward and compresses the gas in the air cylinder 204. This causes the air inside the cylinder to be introduced into the cylinder 202 through the first air pipe 202a, the first connecting pipe 202b, and the second air pipe 204a. After the air pressure in the cylinder 202 increases, it pushes the push plate 203 to move along the surface of the lifting side mold 104 and the mold seat 103, pushing out the formed rock slab blank and excess powder. The formed rock slab blank slides onto the surface of the conveying device 106 and is conveyed out, while the dust falls into the collection box 108 along the guide plate 107. This can clean the dust on the surface of the mold seat 103, ensuring the cleanliness of the production equipment surface and avoiding powder waste.

[0037] Example 2

[0038] Please see Figure 1 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a dust collection component 300 is provided. The dust collection component 300 includes a dust box 301 installed on the upper surface of the base 100, and a second sealing plug 301c movably installed inside the dust box 301. A piston rod 302 is provided in the middle of the upper surface of the second sealing plug 301c. This solves the problem that the existing multi-directional pressure mold for dry pressing of slab blanks causes a large amount of dust to fly in the working environment due to the large amount of powder scattered on the surface of the equipment, which affects the health of production personnel.

[0039] Specifically, an exhaust pipe 301b is provided below the front end face of the dust box 301, and a dust inlet pipe 301a is provided below one side wall of the dust box 301. The top end of the piston rod 302 slides through the sliding hole at the top of the dust box 301 and is connected to the connecting plate 302a. One side wall of the connecting plate 302a is connected to the outer wall of the lifting pressure seat 105 by bolts. The other end of the dust inlet pipe 301a is connected to the second connecting pipe 303 by a pipe joint. The other end of the second connecting pipe 303 is connected to the dust suction hood 303a by a pipe joint.

[0040] Furthermore, the dust box 301 can be used to absorb dust and prevent dust leakage. Both the exhaust pipe 301b and the dust inlet pipe 301a are equipped with one-way valves, meaning that air cannot flow in the opposite direction.

[0041] The operation process of this embodiment is as follows: After the slab blank is integrally pressed and formed, the lifting pressure seat 105 rises and simultaneously drives the connecting plate 302a to rise. Under the action of the piston rod 302, the second sealing plug 301c rises. At this time, the second sealing plug 301c draws in ambient air through the dust suction hood 303a, the second connecting pipe 303, and the dust inlet pipe 301a. At the same time, it sucks the flying dust generated by the falling part of the powder on the guide plate 107 into the dust box 301, so as to avoid a large amount of dust flying in the working environment and affecting the health of production personnel.
