Description

Technical Field

[0001] The utility model relates to the technical field of liquefied petroleum gas cylinder valve production, in particular to a valve body mold for the production of liquefied petroleum gas cylinder valves. Background Art

[0002] Liquefied petroleum gas is a flammable gas, and the cylinder valve is the main safety accessory of the liquefied petroleum gas cylinder. Due to its particularity, many countries require the cylinder valve to be non-detachable and equipped with a safety release device. At present, the hydraulic valve body is basically processed by casting molds. After the valve body is cast in the mold cavity, it is inconvenient to unload, and there is no unloading mechanism installed.

[0003] In the prior art, a Chinese patent document with publication number CN215199561U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a mold for producing a hydraulic valve body, comprising a lower module and an upper module, a casting cavity and a sealing groove are provided in the middle of the lower module, a positioning hole is provided on the outer side of the lower module, an inner mold and a positioning rod are fixedly connected to the bottom of the upper module, a pad is movably installed at the bottom of the inner mold, a connecting rod is fixedly installed in the middle of the pad, the upper side of the connecting rod is sleeved on the middle of the upper module, and a nut is threadedly connected to the upper end of the connecting rod.

[0004] In order to solve the problem that it is inconvenient to unload the valve body after casting in the mold cavity and there is no unloading mechanism, the existing technology adopts the method of setting a pad. However, after casting, it is still necessary to manually disassemble the valve body up and down to take out the material, which leads to a low degree of mechanization of the valve body mold and unstable manual movement, which can easily cause damage to the valve body. Utility Model Content

[0005] The utility model aims to provide a valve body mould for producing a liquefied petroleum gas cylinder valve, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A valve body mold for producing liquefied petroleum gas cylinder valves, comprising a mold box, lifting devices are fixedly installed on both sides of the mold box, a support assembly is fixedly installed on the top surface of the lifting device, an inner mold assembly is movably installed on the surface of the lifting device, and a feeding assembly is movably installed on the top of the inner mold assembly;

[0008] The lifting device comprises a mounting plate, a servo motor, a threaded rod and a sliding rod.

[0009] A further improvement of the technical solution of the utility model is that the mold box includes a mold box body, a casting cavity is opened on the surface of the mold box body, and a snap-in hole is fixedly installed on the top surface of the mold box body. By setting the snap-in hole, the stability of the connection between the mold box body and the inner mold body is improved.

[0010] A further improvement of the technical solution of the utility model is that: the mounting plate is fixedly mounted on both sides of the mold box body, the servo motor is fixedly mounted on the bottom surface of the mounting plate, the threaded rod is fixedly mounted on the output end of the servo motor, and the sliding rod is fixedly mounted on the surface of the mounting plate. By setting a lifting device, after the casting is completed, the servo motor can be started to drive the threaded rod and cooperate with the sliding rod to drive the inner mold assembly and the feeding assembly to move upward, thereby facilitating the unloading of the valve body by rotating the spiral rod in cooperation with the isolation disk.

[0011] A further improvement of the technical solution of the utility model is that: the support assembly includes a reinforcement plate fixedly mounted on the surface of the upper mounting plate, a movable rod fixedly mounted on the surface of the reinforcement plate, and a support rod movably mounted on one end of the movable rod. By setting the support assembly, after the feed assembly is moved to a specified position, the support rod can be rotated on the movable rod to make it contact the bottom of the feed box, thereby supporting it, and then facilitating the reverse driving of the servo motor to separate it from the inner mold assembly.

[0012] A further improvement of the technical solution of the utility model is that the inner mold assembly includes an inner mold body movably mounted on the surface of a threaded rod, a spiral rod is movably mounted on the surface of the inner mold body, and an isolation disk is fixedly mounted on the bottom surface of the spiral rod. The isolation disk can prevent the valve body from directly contacting the mold box body, causing inconvenience in material discharge.

[0013] A further improvement of the technical solution of the utility model is that the feeding assembly includes a feeding box movably installed on the top of the inner mold body, a material guide tube is fixedly installed on the surface of the feeding box, and a spring is fixedly installed on the bottom surface of the feeding box. By setting the spring, a certain shaking can be generated under the influence of gravity during material discharge, thereby promoting the flow speed of the raw materials.

[0014] A further improvement of the technical solution of the utility model is that: the mounting plate and the threaded rod are movably connected, the inner mold body and the sliding rod are movably connected, and the feed box and the inner mold body are movably connected via a spring.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] 1. The utility model provides a valve body mold for the production of liquefied petroleum gas cylinder valves. By setting a lifting device, after the casting is completed, the servo motor is started to drive the threaded rod and cooperate with the sliding rod to drive the inner mold assembly and the feeding assembly to move upward, so as to facilitate the unloading of the valve body by rotating the spiral rod and cooperating with the isolation disk.

[0017] 2. The utility model provides a valve body mold for the production of liquefied petroleum gas cylinder valves. By setting a support assembly, after the feed assembly is moved to a specified position, the support rod can be rotated on the movable rod to make it contact the bottom of the feed box, thereby supporting it, and then facilitating the reverse driving of the servo motor to separate it from the inner mold assembly.

[0018] 3. The utility model provides a valve body mold for the production of liquefied petroleum gas cylinder valves. Through the cooperation of the lifting device and the supporting assembly, the mechanization degree of the valve body mold can be effectively improved, thereby improving the efficiency of material removal. At the same time, it is also convenient to separate the mold box, the inner mold assembly and the feeding assembly after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
