[0004] Although it is possible to demold the hot-pressed products, there are still some problems in daily use. After the hot-pressing is completed, the product is separated from the mold by the mold ejection system. Although it can be separated from the mold, the molded product is still in the hot-pressing machine and needs to be taken out manually. At this time, the temperature of the product itself and the hot-pressing environment it is in is still extremely high, which undoubtedly increases the risk of burns for operators during the retrieval process.

[0005] In view of this, the utility model provides a hot press demoulding device, which can use the unloading component to cause the hot-pressed formed product that has been demoulded to slide smoothly backward under the action of its own gravity and its own inclination to complete automatic unloading without manual intervention, thus avoiding the potential risk of burns caused by workers manually touching the product in a high temperature environment.

[0006] In order to solve the above technical problems, the utility model provides a demoulding device for a hot press machine, comprising a hot press machine body and a demoulding mechanism arranged in the hot press machine body, the demoulding mechanism comprising a mounting groove which is laterally symmetrically arranged on the bottom wall surface of the hot press machine body concave mold, a fixing cylinder is arranged at the rear end of the bottom wall surface of the mounting groove, a rectangular opening is arranged in the middle part of the upper end surface of the fixing cylinder, a rectangular rod is slidably connected in the inside, a top plate is rotatably connected in the notch arranged at the rear side of the upper end of the rectangular rod, the upper surface of the top plate is adapted to the bottom wall surface of the concave mold of the hot press machine body, and a mounting hole is arranged at the front side of the upper end of the rectangular rod. A material discharge assembly is provided in the loading port, and the material discharge assembly includes mounting cylinders respectively arranged in the mounting port, and sliding rods are slidably connected in the sliding holes arranged in the middle of the upper end surface of the mounting cylinder, and the upper ends of the sliding rods are respectively cooperated with the top plates adjacent to the same side, and piston rings are provided at the lower ends of the outer arc surfaces of the sliding rods, and the piston rings are respectively slidably connected with the inner arc surfaces of the mounting cylinders adjacent to the same side, and transmission pipes are provided between the air inlet arranged at the lower end of the outer arc surface of the mounting cylinder and the air outlet arranged at the upper end of the outer arc surface of the fixed cylinder adjacent to the same side, and a transmission assembly is provided at the upper end of the sliding rod.

[0007] The lower ends of the sliding rods are all provided with weight blocks, and the weight blocks are respectively matched with the bottom wall surfaces of the adjacent installation cylinders on the same side.

[0008] The demolding mechanism also includes piston plates respectively arranged at the lower ends of the rectangular rods, the piston plates are respectively slidably connected to the inner arc surfaces of the adjacent fixed cylinders on the same side, the vents arranged at the lower ends of the outer arc surfaces of the fixed cylinders are each provided with an air intake pipe, the front ends of the air intake pipes penetrate the front surface of the hot pressing body and extend to the outside, the exhaust ports arranged at the lower sides of the front ends of the outer arc surfaces of the air intake pipes are each provided with an electric exhaust valve, and the electric exhaust valves are electrically connected to the external single-chip computer; the demolding mechanism also includes air holes respectively arranged at the rear ends of the upper end surfaces of the fixed cylinders.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. First, the relevant staff connects the air intake pipe to the external compressor. When the auto interior accessories are hot-pressed and need to be demolded, the external single-chip computer controls the external compressor to start working. The external compressor sends high-pressure gas into the fixed cylinder through the air intake pipe. After the high-pressure gas is injected into the fixed cylinder, it pushes the piston plate, rectangular rod, top plate, counterweight, mounting cylinder, sliding rod, piston ring, piston ring and weight block to move upward synchronously. As the top plate rises steadily, the hot-pressed product is also lifted up smoothly and separated from the mold, thereby achieving the demolding effect.

[0014] 2. When the top plate reaches the preset telescopic position, the piston plate will just pass over the air outlet and close the air hole, causing the gas to be diverted and flow into the installation cylinder through the transmission pipe. This airflow then pushes the piston ring, sliding rod and weight block to rise again. At the same time, the front end of the sliding rod lifts the top plate, causing the hot-pressed molded product that has been demolded to slide smoothly backwards under its own gravity and inclination to complete automatic unloading without manual intervention, avoiding the potential risk of burns caused by workers manually touching the product in a high temperature environment.

[0015] 3. When the sliding rod pushes the top plate, the sliding rod cooperates with the arc-shaped guide groove through the ball head, thereby greatly reducing the friction between the sliding rod and the top plate when they slide relative to each other, ensuring the accuracy and smoothness of the entire demoulding action.

[0024] like Figure 2-4 As shown, a weight block 500 is disposed at the lower end of the sliding rod 401 , and the weight block 500 is respectively matched with the bottom wall surface of the adjacent mounting tube 400 on the same side.

[0025] like Figure 2-4 As shown, the lower surface of the rectangular rod 202 is provided with a counterweight block 300, and the counterweight block 300 is respectively arranged to cooperate with the bottom wall surface of the adjacent fixing tube 201 on the same side.

[0026] like Figure 1-3 As shown, both left and right ends of the bottom wall of the concave mold of the hot press body 100 are provided with accommodating grooves 700 corresponding to the top plate 204 one by one.

[0027] The working principle of the demoulding device of a hot press provided by the utility model is as follows: first, the relevant staff connects the air intake pipe 206 with the external compressor. When the hot pressing molding of the automobile interior accessories is completed and the demoulding is required, the external single chip computer controls the external compressor to start working, and the external compressor sends the high-pressure gas into the fixed cylinder 201 through the air intake pipe 206. After the high-pressure gas is injected into the fixed cylinder 201, the piston plate 203, the rectangular rod 202, the top plate 204, the counterweight block 300, the installation cylinder 400, the sliding rod 401, and the piston ring 40 2. The piston ring 402 and the weight block 500 move upward synchronously. As the top plate 204 is steadily lifted, the hot-pressed product is also lifted up and separated from the mold smoothly, thereby achieving the demoulding effect. When the top plate 204 reaches the preset telescopic position, the piston plate 203 will just pass over the gas outlet and close the air hole 205, causing the gas to be diverted and flow into the installation cylinder 400 through the transmission pipe 403. This airflow then pushes the piston ring 402, the sliding rod 401 and the weight block 500 to rise again, and at the same time, the front end of the sliding rod 401 lifts the top plate 204 , which enables the demoulding hot-pressed products to slide back smoothly under their own gravity and inclination to complete automatic unloading without manual intervention, thus avoiding the potential risk of burns caused by workers manually touching the products in a high temperature environment. Once the hot-pressed products are completely unloaded, the external single chip machine timely controls the external compressor to stop running, and simultaneously opens the electric exhaust valve 207, so that the high-pressure gas in the fixed cylinder 201 can be quickly discharged, so that the piston plate 203, the rectangular rod 202, the top plate 204, the counterweight block 300, and the installation cylinder 40 0. The sliding rod 401, the piston ring 402, and the weight block 500 are orderly reset to the initial state under the action of gravity. During this reset process, the air hole 205 is reconnected with the transmission pipe 403, and the gas in the installation cylinder 400 is discharged through the transmission pipe 403 and the air hole 205, ensuring that the sliding rod 401 and the piston ring 402 move downward and reset in coordination under the gravity traction of the weight block 500, and finally the top plate 204 is smoothly embedded in the corresponding receiving groove 700, and the whole set of equipment is ready for the next round of efficient hot pressing operation of automotive interior accessories.

[0028] like Figure 2-3As shown, the transmission assembly includes ball grooves respectively arranged at the upper ends of the sliding rods 401, in which ball heads 600 are rotatably connected, and the front ends of the lower surfaces of the top plates 204 are provided with arc guide grooves 601 corresponding to the ball heads 600 one by one. When the sliding rod 401 pushes the top plate 204, the sliding rod 401 cooperates with the arc guide grooves 601 through the ball heads 600, thereby greatly reducing the friction force when the sliding rod 401 and the top plate 204 slide relative to each other, thereby ensuring the accuracy and smoothness of the entire demoulding action.

[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
