Description

Technical Field

[0001] This utility model relates to the field of bus seat molding mold technology, specifically a bus seat molding mold. Background Technology

[0002] Bus seat molding dies are the core equipment for the industrial production of bus seats. Their role is involved in the entire process of seat design implementation, mass production, quality control and functional realization, and directly affects the structural performance, production efficiency and user experience of the seats.

[0003] For example, a mold for seat molding with authorization announcement number "CN210634037U" has mold feet on the left and right sides of the ejector plate panel, and hydraulic cylinders connected to the upper and lower parts of the ejector plate panel. Compared with the prior art, a pair of slots can be injection molded on the back of the seat through the cooperation of the fixed mold, the moving mold and the inclined ejector. In the subsequent assembly process, steel plates can be inserted into the slots. In this way, the assembly between the seat shell and the seat frame is more secure. However, in the use of bus seat molding molds, there are many water pipe interfaces and they are densely distributed. Moreover, the upper mold needs to be raised and lowered to achieve the closing and opening of the lower mold, which will generate a certain amount of vibration. After long-term use, water leakage may occur due to vibration, causing water to seep into the inside of the bus seat molding mold and affecting the normal molding inside the bus seat molding mold. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of water seepage into the mold of bus seats, which affects the normal molding process inside the mold, and to propose a bus seat molding mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a bus seat molding die, including a lower bus seat die, with control structures connected to the left and right sides of the lower bus seat die, and an upper bus seat die fixed to the inner side of the control structures. Multiple straight tubes are connected through the inner walls of both the upper and lower bus seat dies, and the ends of the straight tubes are connected to reinforcement structures.

[0007] Preferably, the reinforcing structure includes a joint and a bend, the inner wall of the joint is threaded to the outer wall end of the straight pipe, the outer side of the joint is rotatably connected to the outer wall end of the bend, a ring is fixedly connected to the outer wall of the bend, and a bend plate is fixedly connected to the outer wall of the ring.

[0008] Preferably, the inner sides of the outer walls of the plurality of curved plates are respectively fitted to the outer walls of the lower mold and the upper mold of the bus seat.

[0009] Preferably, the bottom of the front and rear sides of the lower mold of the bus seat is fixedly connected to the ends of multiple slot plates.

[0010] Preferably, the inner wall of the groove plate is machined with an opening.

[0011] Preferably, the control structure includes a first square plate and a cylinder. The inner sides of the two first square plates are respectively fixedly connected to the left and right sides of the lower mold of the bus seat. The top of the first square plate is fixedly connected to the bottom of the cylinder. The output end of the cylinder is fixedly connected to a second square plate.

[0012] Preferably, the inner sides of the two second square plates are fixedly connected to the left and right sides of the upper mold of the bus seat, respectively.

[0013] The present invention proposes a bus seat forming mold, which has the following advantages: By reinforcing the structure with threaded connections between the inner wall of the joint and the outer wall of the straight pipe, and by staggering the connections between the ends of the straight pipes on both sides of the upper and lower bus seat molds and the joint, the combined effect of the bent pipes creates a connected serpentine tube from multiple straight pipes. After the joint and the straight pipes are connected, the ends of multiple bent plates will fit against the outer walls of the upper and lower bus seat molds. Then, bolts, threaded from the outside in, pass through the outer circular opening of the bent plate and connect with the outer circular opening of the upper and lower bus seat molds, thus fixing the positions of the bent plates and the rings. At this point, the bent plates and the rings support the bent pipes, preventing complete deformation at the joint and the bent pipe connection point, thus preventing water leakage and water seepage into the bus seat forming mold, ensuring normal molding inside the mold.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Please see Figure 1-5 In this embodiment, a bus seat forming mold includes a lower bus seat mold 1. Control structures 3 are connected to the left and right sides of the lower bus seat mold 1, and an upper bus seat mold 6 is fixed to the inner side of the control structure 3. Multiple straight pipes 7 are connected through the inner walls of both the upper bus seat mold 6 and the lower bus seat mold 1. The outermost straight pipe 7 in both the lower bus seat mold 1 and the upper bus seat mold 6 has a flange at the front end of its outer wall and a thread at the rear end of its outer wall. The ends of the outer walls of the other straight pipes 7 are also threaded. A reinforcing structure 2 is connected to the end of each straight pipe 7.

[0022] The reinforcement structure 2 includes a joint 201 and a bend 202. The inner wall of the joint 201 is threaded to the outer wall end of the straight pipe 7, and the outer side of the joint 201 is rotatably connected to the outer wall end of the bend 202. The joint 201 rotates under force through the sealed bearing at the outer wall end of the bend 202. A ring 203 is fixed to the outer wall of the bend 202. The bend 202 is a flexible tube. A bent plate 204 is fixed to the outer wall of the ring 203. The inner sides of the outer walls of the multiple bent plates 204 are respectively attached to the outer walls of the lower mold 1 and the upper mold 6 of the bus seat.

[0023] By reinforcing the structure 2, the inner wall of the connector 201 is threaded to the outer wall of the straight pipe 7. At the same time, the ends of the straight pipes 7 on the front and rear sides of the upper and lower molds of the bus seat are staggered with the connector 201. This, combined with the bend 202, will make multiple straight pipes 7 form a connected serpentine tube. After the connector 201 and the straight pipe 7 are connected, the ends of multiple bends 204 will fit against the outer walls of the upper and lower molds of the bus seat. Then, the bolts are threaded from the outside to the inside through the outer round opening of the bend 204 and threaded to the outer round opening of the upper and lower molds of the bus seat, thus fixing the position of the bend 204 and the ring 203. At this time, the bend 204 and the ring 203 support the bend 202, which can prevent the joint 201 and the bend 202 from being completely deformed, avoid water leakage, prevent water from seeping into the bus seat molding mold, and ensure normal molding inside the bus seat molding mold.

[0024] The bottom of the front and rear sides of the lower mold 1 of the bus seat is fixedly connected to the ends of multiple slot plates 4. The inner wall of the slot plate 4 is machined with a through opening 5. The control structure 3 includes a first square plate 301 and a cylinder 302. The inner sides of the two first square plates 301 are fixedly connected to the left and right sides of the lower mold 1 of the bus seat. The top of the first square plate 301 is fixedly connected to the bottom of the cylinder 302. The cylinder 302 is a multi-section cylinder with a self-locking function at the output end. The output end of the cylinder 302 is fixedly connected to a second square plate 303. The inner sides of the two second square plates 303 are fixedly connected to the left and right sides of the upper mold 6 of the bus seat.

[0025] Working principle:

[0026] Bus seat molding die pipe connection:

[0027] The inner wall of connector 201 is threaded to the outer end of the straight pipe 7. Simultaneously, the ends of the straight pipes 7 on both sides of the upper and lower bus seat molds 6 and 1 are staggered with connector 201. This, combined with bend 202, creates a connected serpentine tube from multiple straight pipes 7. After connector 201 and the straight pipes 7 are aligned, the ends of multiple bends 204 fit against the outer walls of the upper and lower bus seat molds 6 and 1. Then, bolts, threaded from the outside in, pass through the outer opening of the bend 204 and connect to the bus seat... The outer wall of the upper mold 6 and the lower mold 1 of the bus seat are connected by a circular thread to fix the position of the bent plate 204 and the ring 203. At this time, the bent plate 204 and the ring 203 support the bent pipe 202, which can prevent the joint 201 from being completely deformed at the joint with the bent pipe 202. Then, the straight pipe 7 on the left side of the front of the upper mold 6 and the lower mold 1 of the bus seat are connected to the water inlet pipe with the end flange, and the end flange of the straight pipe 7 on the right side of the front of the upper mold 6 and the lower mold 1 of the bus seat is connected to the water outlet pipe.

[0028] Bus seat molding process:

[0029] The injection material for the bus seat is fed into the upper mold 6 through the sprue at the top. The material then fills the space between the lower mold 1 and the upper mold 6. Next, cold water is introduced through the straight pipe 7 on the left side of both the upper and lower molds. Multiple straight pipes 7 and multiple bends 202 form a serpentine system, allowing the cold water to carry away heat from the injection material within the molds. The water then exits through the straight pipe 7 on the right side, thus cooling the injection material inside the upper and lower molds. Once the water temperature drops after exiting through the straight pipe 7, the cylinder 302 is energized, causing the output end to move upwards along with the second square plate 303. This movement of the second square plate 303 then moves the upper mold 6 upwards, detaching it from the lower mold 1. The bus seat model is then removed from the lower mold 1.

[0030] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
