Description

Technical Field

[0001] The utility model relates to a group mould erecting machine, in particular to a hydraulic cylinder locking mechanism in a side locking device of the group mould erecting machine. Background Art

[0002] The side locking device of the group mold (machine) has a hydraulic cylinder locking mechanism and a locking rod assembly. The hydraulic cylinder locking mechanism is arranged in pairs, and each pair of hydraulic cylinder locking mechanisms is respectively arranged on the left and right sides of the template system. In the template system, the left and right sides of the mobile section mold are respectively connected to the left and right sides of the fixed section mold through a pair of the hydraulic cylinder locking mechanisms. The hydraulic cylinder locking mechanism has a hydraulic cylinder, a locking rod, a fixed section mold, and a mobile section mold. The cylinder end of the hydraulic cylinder is hinged to the side of the fixed section mold, and the outer end of the locking rod is hinged to the side of the mobile section mold. The locking rod has only one section, and the outer end of the locking rod is connected to the moving section mold. When the hydraulic cylinder locking mechanism is opened, the locking rod rotates to the back of the moving section mold. The entire locking rod only rotates 180° on the side. Whether on the side of the moving section mold or behind the moving section mold, the locking rod occupies a large space. In this way, the hydraulic cylinder locking mechanism occupies a large space, which is inconvenient for workers to operate and affects the production efficiency of the group mold machine.

CN219746053U discloses an automatically rotatable side locking device for group molds, which has a template system, a pair of hydraulic cylinder locking mechanisms, and two pairs of locking rod assemblies; its characteristics are that each of the hydraulic cylinder locking mechanisms also has a first power device for driving the hydraulic cylinder to rotate when completing the opening and closing actions of the hydraulic cylinder locking mechanism, and a second power device for driving the locking rod body to rotate; each of the locking rod assemblies also has a third power device for driving the locking rod to rotate when completing the opening and closing actions of the locking rod assembly.

[0004] The locking rod of the hydraulic cylinder locking mechanism in the above technology has only one section (a one-section structure). When the hydraulic cylinder locking mechanism is opened, the locking rod occupies a large space, which makes it inconvenient for workers to operate subsequent work. Summary of the invention

[0005] The utility model aims to provide a hydraulic cylinder locking mechanism in a side locking device of a group mold, which can reduce the space occupied by the hydraulic cylinder locking mechanism when it is opened, thereby facilitating the operation of workers and improving the production efficiency of the group mold machine.

The cylinder end of the hydraulic cylinder is hinged to the side of the fixed section mold, and the outer end (right end) of the locking rod is hinged to the side of the movable section mold. The technical solution is that a retractable tension rod is provided between the hydraulic cylinder and the locking rod, one end of the tension rod is hinged to the inner end (left end) of the locking rod, and when the hydraulic cylinder locking mechanism is in a tensioned state, the other end of the tension rod is detachably connected to the piston rod of the hydraulic cylinder. When the hydraulic cylinder locking mechanism is in an open state, the tension rod moves to the back of the movable section mold (the tension rod is located behind the movable section mold).

[0015] In order to make the invention purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described in combination with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the hydraulic cylinder locking mechanism in the side locking device of the group mold of the utility model comprises a hydraulic cylinder 1, a locking rod 3, a fixed section mold 5 and a movable section mold 4. The cylinder end of the hydraulic cylinder 1 is hinged to the side of the fixed section mold 5, and the outer end of the locking rod 3 is hinged to the side of the movable section mold 4. A retractable tension rod 2 is provided between the hydraulic cylinder 1 and the locking rod 3, one end of the tension rod 2 is hinged to the inner end of the locking rod 3, and when the hydraulic cylinder locking mechanism is in a tensioned state, the other end of the tension rod 2 is detachably connected to the piston rod of the hydraulic cylinder 1. When the hydraulic cylinder locking mechanism is in an open state, the tension rod 2 is rotated to the back of the movable section mold 4. The structure in which one end of the above-mentioned tension rod 2 is detachably connected to the piston rod of the hydraulic cylinder 1 is that the top of the piston rod of the hydraulic cylinder 1 is provided with a circular ring groove 101, and one end of the tension rod 2 is provided with a cavity 201, and the top of the cavity 201 (or the left side wall of the cavity) has an opening 202. The circular ring groove 101 at the top of the piston rod cooperates with the opening 202 at the top of the cavity 201 so that the tension rod 2 hooks the head of the piston rod of the hydraulic cylinder 1 (to realize the joint connection).

[0017] The hydraulic cylinder locking mechanisms are arranged in pairs, and each pair of hydraulic cylinder locking mechanisms is respectively arranged on the left and right sides of the template system. In the template system, the left and right sides of the movable section mold 4 are respectively connected to the left and right sides of the fixed section mold 5 through a pair of the hydraulic cylinder locking mechanisms. Reference numeral 6 is a folding tension rod (of the group mold).

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the group mold erecting machine pre-tightens the template system (former) by pulling the retractable tension rod 2 and locking rod 3 through the hydraulic cylinder, and then fixes it through the locking rod body assembly to achieve the purpose of tensioning and form a stable mold cavity. Operation process: ① Start the driving motor of the mobile section form to push the form group to form a mold cavity. ② Manually rotate the tension rod 2 and locking rod 3 to the side of the form system, rotate the hydraulic cylinder 1 to the side of the form system, and make the tension rod 2 hook the head of the piston rod of the hydraulic cylinder 1 to achieve joint connection. ③ Start the hydraulic cylinder 1 and pre-tighten. ④ Connect the folding tension rod body in the locking rod body assembly and lock it. ⑤ Pour concrete to generate components. ⑥ Disconnect the connection between the hydraulic cylinder 1 and the tension rod, and rotate the tension rod 2 and locking rod 3 to the back of the mobile section form 4. ⑦ Make the locking rod body assembly in the open state, open the mold cavity, take out the component, and start the next cycle.

[0019] The utility model provides a hydraulic cylinder locking mechanism in the side locking device of the group mold. When the hydraulic cylinder locking mechanism is opened, after the locking rod 3 rotates 180°, the retractable tension rod 2 rotates 90° again and completely turns to the back of the moving section mold 4 (that is, turns to the back of the moving section mold 4), and the space occupied is smaller. Therefore, the space occupied by the hydraulic cylinder locking mechanism becomes smaller, which is convenient for the subsequent operation of the workers and improves the production efficiency of the group mold machine. The utility model solves the problem that the hydraulic cylinder locking mechanism (or the original locking rod) occupies a large space and is inconvenient for workers to operate. After adopting the hydraulic cylinder locking mechanism of the utility model, the production efficiency of the group mold machine is improved by more than 5%.
