[0002] A pneumatic molding machine is an industrial device that uses pneumatic drive to compress and shape materials. It is widely used in powder metallurgy, ceramic molding, plastic product processing and food manufacturing. Its core working process relies on the vertical movement of the cylinder piston to drive the extrusion plate to apply pressure to the material in the mold, combined with a fixed limiting structure to ensure the molding path.

[0003] However, existing pneumatic molding machines have rigid limiting structures that cannot be flexibly adjusted during use, and can only be adapted to a single mold size. At the same time, when there is a lot of material inside, it is inconvenient to move the material cylinder from under the extrusion plate to the edge of the molding machine. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic molding machine to solve the problems mentioned in the background art.

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

[0011] Preferably, the telescopic rod is dynamically connected to the sleeve through a pre-tightened elastic element, wherein the elastic element is a compression spring, and its two ends abut against the inner wall of the sleeve and the end face of the telescopic rod, respectively.

[0012] Preferably, the pneumatic drive module includes a cylinder, an oil-water separator, a cylinder valve, and an exhaust muffler box, with an upper air port and a lower air port respectively provided at the top and bottom of the cylinder.

[0013] Preferably, the air inlet of the oil-water separator is connected to an external air source, and the air outlet is connected to the upper and lower air ports of the cylinder through cylinder valves.

[0014] Preferably, the exhaust muffler box is connected to the exhaust end of the cylinder valve.

[0015] Preferably, both the bottom frame and the support frame are provided with modular expansion interfaces on their sides, and these interfaces include arrays of positioning holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-3 As shown, a pneumatic molding machine includes:

[0026] The bottom frame assembly consists of a bottom frame 1 made of several square tubes, and a storage cavity 11 is provided inside it. A pull-out storage unit with a sliding rail structure is slidably arranged in the storage cavity 11.

[0027] The top support assembly includes a support frame 3 fixed above the bottom frame 1. The top of the support frame 3 is provided with a pneumatic drive module 4, the output end of which is connected to a vertically lifting extrusion plate 5.

[0028] The limiting structure 6 is symmetrically arranged on both sides of the support frame 3. It includes a support base 61 rigidly connected to the support frame 3, a sleeve 62 rotatably installed on the support base 61, a telescopic rod 63 nested in the sleeve 62 and slidably connected thereto, and a limiting member 64 set at the end of the telescopic rod 63. The limiting member 64 includes a straight rod section with a guide groove and an arc-shaped section matching the outer contour of the extrusion barrel. A handle 9 is fixedly installed on the straight rod section 8. A workstation coaxial with the extrusion plate 5 is set at the top of the bottom frame 1.

[0029] In one embodiment of the present invention, the pull-out storage unit includes a storage frame 2 with a discharge port 22 at the bottom. The discharge port 22 is equipped with a flow regulating valve 21. The storage frame 2 has sliding mechanisms on both sides that cooperate with the slide rail of the bottom frame 1, and is equipped with a pull-out operation handle 23.

[0030] In one embodiment of this utility model, the telescopic rod 63 is dynamically connected to the sleeve 62 through a pre-tightened elastic element. The elastic element is a compression spring, and its two ends abut against the inner wall of the sleeve 62 and the end face of the telescopic rod 63, respectively.

[0031] In one embodiment of the present invention, the pneumatic drive module 4 includes a cylinder 41, an oil-water separator 42, a cylinder valve 43, and an exhaust muffler box 44. The top and bottom of the cylinder 41 are respectively provided with an upper air port 411 and a lower air port 412.

[0032] In one embodiment of the present invention, the air inlet of the oil-water separator 42 is connected to an external air source, and the air outlet is connected to the upper air port 411 and the lower air port 412 of the cylinder 41 through the cylinder valve 43.

[0033] In one embodiment of this utility model, the exhaust muffler box 44 is connected to the exhaust end of the cylinder valve 43.

[0034] In one embodiment of the present invention, both the bottom frame 1 and the support frame 3 are provided with modular expansion interfaces on their sides, and the interfaces include arrayed positioning hole groups 7.

[0035] As can be seen from the above, the external air source pipe is connected to the air inlet of the oil-water separator 42, the extrusion barrel or molding die is placed at the work station at the top of the bottom frame 1, and pushed and aligned with the extrusion plate 5. During the pushing process, the extrusion barrel or molding die contacts the limiting member 64, and the pre-tightened elastic element is squeezed by the telescopic rod 63. The arc section of the limiting member 64 fits the outer contour of the extrusion barrel, reducing the movement of the extrusion barrel or molding die.

[0036] The material to be formed, such as powder or soft material, is filled into the extrusion barrel. The surface is flat. The cylinder valve 43 is opened. After the oil-water separator 42 filters the air source, it supplies air to the upper air port 411. The piston rod of the cylinder 41 drives the extrusion plate 5 to press down vertically. After the extrusion plate 5 contacts the material, it continues to be pressurized. After reaching the preset pressure, the cylinder valve 43 switches the air path, closes the upper air port 411, and supplies air to the lower air port 412. The piston rod retracts, the extrusion plate 5 rises and resets, and the cylinder exhaust gas is discharged through the exhaust silencer box 44 to reduce noise.

[0037] Then push the handle 8 upwards to make the limiting component 64 rotate around the sleeve 62 as the center, and push the extrusion barrel or molding die outwards at the end of the arc section for easy handling;

[0038] The liquid or waste generated by extrusion is pulled out of the collection frame 2 by pulling the operating handle 23, and the waste is discharged through the discharge port 22. The flow regulating valve 21 controls the discharge rate.

[0039] The bottom frame 1 and the support frame 3 are connected by a set of positioning holes 7 on the sides, allowing several pneumatic molding machines to be interconnected.
