Abstract
Description
Technical Field
[0001] This utility model relates to the field of artificial stone production and processing technology, specifically a press for artificial stone production. Background Technology
[0002] The press for artificial stone production is a mechanical device specifically designed for the production of artificial stone materials. Its principle is to use high pressure and stirring to mix the stone raw materials and adhesive evenly and then press them into shape, ultimately obtaining artificial engineered stone with high strength and beautiful appearance.
[0003] The raw material is injected into the mold and pressed by a hydraulic rod. Due to the long pressing time, the formed stone slab may stick to the hydraulic rod after the material is formed, resulting in uneven stress on the stone slab and breakage. This affects the quality of the final product. In addition, the formed stone slab itself has a certain weight and is not easy to demold, which has limitations.
[0004] The reason for this problem is that the pressing process usually takes a long time, during which the raw material gradually solidifies under high pressure. During this process, the raw material undergoes a chemical reaction or physical adsorption with the surface of the hydraulic rod, causing the formed stone slab to stick to the hydraulic rod. During pressure release or demolding, the hydraulic rod applies uneven force to the stone slab, resulting in uneven stress. This uneven stress can cause the stone slab to crack or break, severely affecting the integrity and aesthetics of the finished product. The formed stone slab itself has a certain weight. This makes it difficult for the stone slab to be smoothly removed from the mold during demolding due to gravity, especially when adhesion exists, further increasing the demolding difficulty and reducing demolding efficiency. Therefore, we propose a press for artificial stone production to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a press for the production of artificial stone. It solves the problems of injecting raw materials into a mold and pressing the raw materials with a hydraulic rod. Due to the long pressing time, the formed stone slab sticks to the hydraulic rod after the raw materials are finally formed, resulting in uneven stress on the stone slab and breakage, which affects the quality of the final product. In addition, the formed stone slab itself has a certain weight and is not easy to demold, which has limitations.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a press for producing artificial stone, comprising a machine body, an upper mold provided at the upper end of the machine body, a lower mold provided at the lower end of the machine body, and a push-pull unit for facilitating the demolding of stone slabs provided inside the machine body, the push-pull unit comprising;
[0007] The skateboard is slidably connected to the inside of the upper mold;
[0008] The first push-pull cylinder is fixedly mounted on the top of the upper mold. The first push-pull cylinder is used to drive the slide plate to move toward or away from the lower mold.
[0009] The bumps are located on the bottom of the skateboard and are arranged in a rectangular array. The ends of the bumps abut against the slab.
[0010] Preferably, the side wall of the lower mold is fixedly connected with a rubber strip, and the bottom of the lower mold is provided with a movable base plate.
[0011] Preferably, an electric push rod is fixedly installed inside the machine body, and a support plate is fixedly installed at the output end of the electric push rod. The support plate is fixedly connected to the movable base plate, and the electric push rod is used to push the stone slab to demold.

[0015] Preferably, a torsion spring is provided on the outer surface of the rotating shaft, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end of the torsion spring is fixedly connected to the upper mold.
[0016] This utility model discloses a press for the production of artificial stone, which has the following beneficial effects:
[0017] This device pushes the protrusion downwards, changing the surface contact between the upper mold and the stone slab to point contact, effectively preventing the stone slab from sticking to the upper mold. When the upper mold moves upwards, it does not pull the stone slab upwards with it, preventing cracks in the stone slab due to uneven force. Through the combined use of electric push rod, second push-pull cylinder and conveyor belt, it can quickly demold the stone slab while ensuring its quality, meeting the needs of users.

[0034] Example 2
[0035] This utility model discloses a press for the production of artificial stone. More specifically, based on Embodiment 1, it is provided according to the appendix... Figure 1 , 3 As shown in Figure 4, the machine includes a body 1, an upper mold 11 is provided at the upper end of the machine body 1, a lower mold 12 is provided at the lower end of the machine body 1, and a push-pull unit 2 for facilitating the demolding of the stone slab is provided inside the machine body 1. The push-pull unit 2 includes:
[0036] Slide 21 is slidably connected to the inside of the upper mold 11;
[0037] The first push-pull cylinder 22 is fixedly mounted on the top of the upper mold 11. The first push-pull cylinder 22 is used to drive the slide plate 21 to move toward or away from the lower mold 12.
[0038] The protrusions 23 are located at the bottom of the slide plate 21. The protrusions 23 are arranged in a rectangular array and the ends of the protrusions 23 abut against the stone slab.
[0039] A flip plate 211 is provided below the protrusion 23. A rotating shaft 212 is fixedly connected inside the flip plate 211. The rotating shaft 212 is rotatably connected to the upper mold 11.
