Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, and in particular to a blow molding device for stadium seats. Background Technology

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began during World War II for the production of low-density polyethylene bottles. In the late 1950s, with the advent of high-density polyethylene and the development of blow molding machines, blow molding technology gained widespread application. Hollow containers can reach volumes of several thousand liters, and some production processes are now computer-controlled. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, and polyester, and the resulting hollow containers are widely used as industrial packaging containers. Based on the preform manufacturing method, blow molding can be divided into extrusion blow molding and injection blow molding. Newer methods include multilayer blow molding and stretch blow molding. Blow molding equipment is commonly used in the production of stadium seating.

[0003] In existing venue seat blow molding equipment, the molds used for blow molding are usually fixed with bolts. When producing different models and sizes of seats, multiple bolts need to be removed to replace the molds, which is cumbersome and inconvenient to use. Therefore, we propose a venue seat blow molding equipment to solve the above-mentioned problems. Utility Model Content

[0030] As a preferred embodiment of this utility model, the mounting mechanism includes: two push plates 9, two transmission plates 10, four unlocking rods 15 and four positioning plates 17;

[0031] Two push plates 9 are slidably connected to the two horizontal plates 6 on opposite sides. Two transmission plates 10 are fixedly connected to the rear side of the corresponding push plates 9. Four unlocking rods 15 are symmetrically rotatably connected to one side of the corresponding push plates 9. Four positioning plates 17 are symmetrically slidably connected to the two horizontal plates 6 on opposite sides. One side of the positioning plate 17 is rotatably connected to one side of the unlocking rod 15. One side of the clamping plate 18 is fixedly connected to one side of the corresponding positioning plate 17. When the push plates 9 move, they will drive the transmission plates 10 to move backward. When the transmission plates 10 move, they will compress the return spring 14. At the same time, the guide plate 11 will encounter the transmission plate 10 and limit it, so that the transmission plate 10 moves stably. The movement of the transmission plate 10 will pull the unlocking rods 15. At this time, the movement of the unlocking rods 15 will drive the positioning plates 17 to move. At this time, the two positioning plates 17 on the same side move to the side closer to each other, compressing the positioning spring 16 and driving the clamping plate 18 to move and disengage from the mounting frame 8, so that the mold 7 is unlocked.

[0032] As a preferred embodiment of this utility model, each of the two horizontal plates 6 is fixedly connected to a vertical plate 13 on the side away from each other. The front side of the two vertical plates 13 is in movable contact with the rear side of the corresponding mounting frame 8. Each of the two vertical plates 13 is fixedly connected to a return spring 14. The front side of the return spring 14 is fixedly connected to the rear side of the transmission plate 10. The spring force of the return spring 14 facilitates pushing the transmission plate 10 to reset.

[0033] As a preferred embodiment of this utility model, guide plates 11 are symmetrically fixedly connected to the sides of the two horizontal plates 6 that are far apart from each other, and there are four guide plates 11. One side of the four guide plates 11 is slidably connected to one side of the corresponding transmission plate 10. The guide plates 11 facilitate the limiting of the transmission plate 10, so that the transmission plate 10 can move laterally stably.

[0034] As a preferred embodiment of this utility model, a positioning spring 16 is fixedly connected to one side of each of the four guide plates 11. One side of the positioning spring 16 is fixedly connected to one side of the corresponding positioning plate 17.

The inner wall of the hollow plate 12 is slidably connected to the outer wall of the push plate 9. The hollow plate 12 facilitates the limiting of the push plate 9, so that the push plate 9 can move stably.

[0036] It should be noted that the specific model of the mold head 3, hydraulic rod 5, and mold 7 should be selected by those skilled in the art. Furthermore, the above-mentioned mold head 3, hydraulic rod 5, and mold 7 are all existing technologies, and this solution will not elaborate on them.

[0037] The working principle of this utility model is as follows: In actual use, when blow molding of venue seats is required, firstly, mold 7 is installed according to the usage requirements. Two molds 7 are placed symmetrically on the top of the base 1. Then, push plate 9 is pushed backward. When push plate 9 moves, it will drive transmission plate 10 to move backward. When transmission plate 10 moves, it will compress return spring 14. At the same time, guide plate 11 will encounter transmission plate 10 and be limited, so that transmission plate 10 moves stably. The movement of transmission plate 10 will pull unlocking rod 15. At this time, the movement of unlocking rod 15 will drive positioning plate 17 to move. At this time, the two positioning plates 17 located on the same side move towards each other, compressing positioning spring 16 and driving clamping plate 18 to move. Then, the mounting frame 8 is installed. The corresponding horizontal plate 6 is passed through, and the mounting frame 8 is aligned with the clamping plate 18. At this time, the push plate 9 is released, the return spring 14 loses its restraint and pushes the transmission plate 10 to reset, and drives the push plate 9 to reset. At the same time, the positioning spring 16 loses its restraint and pushes the positioning plate 17 to reset, so that the clamping plate 18 and the mounting frame 8 are engaged, thereby fixing the mold 7 and keeping the mold 7 fixed. At this time, the die head 3 is connected to the blow molding machine, and the plastic raw material is extruded through the die head 3. By starting the hydraulic rod 5, the two molds 7 can be moved to the side that is closer to each other to close the mold. After the plastic is formed, by controlling the hydraulic rod 5 to reset, the two molds 7 can be moved to the side that is farther away from each other, thereby achieving the effect of blow molding of the stadium seats.
