[0012] The utility model discloses an upper mold is opened or closed on the lower mold through a mold frame of a production line, and a turning block cylinder pushes the turning block of the lower mold to open and turn to be separated from or closed on the lower mold. When pouring material, the turning block of the lower mold is closed, and foam is injected from an opening on the surface of one end of the lower mold. After the injection is completed, the upper mold is closed, and the product begins to foam. After the foaming is completed, the upper mold is opened, and the turning block cylinder pushes the turning block of the lower mold to open and manually take out the product. Compared with the previous mold structure, this structure is easier to discharge gas, avoids the scrapping of sponge due to exhaust, improves production efficiency, and reduces the scrap rate.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A closed mold casting structure for a handrail foaming mold comprises an upper mold 1 and a lower mold 3. The upper mold 1 is mounted on a mold frame passing through a production line, and is opened and closed on the lower mold 3 through the mold frame of the production line. A skeleton positioning block 6 is slidably arranged above the mold cavity of the lower mold 3, and both sides of one end of the lower mold 3 are provided with a positioning skeleton slider cylinder 5 for moving the skeleton positioning block 6. The lower mold 3 is located above the skeleton positioning block 6 and is closed with a lower mold flip block 2, and a flip block cylinder 4 for driving the lower mold flip block 2 to flip is installed on one side of the lower mold 3.

[0020] Two sets of hinges 7 are symmetrically fixedly installed on one end surface of the lower mold 3, and one side of the top of the two sets of hinges 7 is fixedly connected to one side of the lower mold flip block 2, so that the lower mold flip block 2 can be flipped out of the closure with the lower mold 3 or closed on the lower mold 3 through the cooperation of the two sets of hinges 7.

[0021] The flip block cylinder 4 is rotatably installed on one side wall of the lower mold 3 through a pin shaft, and one end of the piston rod of the flip block cylinder 4 is rotatably installed on one side wall of the lower mold flip block 2 through a pin shaft, so that the lower mold flip block 2 can be pushed by the flip block cylinder 4 to open and flip, disengage from the closure with the lower mold 3, or close on the lower mold 3.

[0022] Cylinder seats are fixedly installed on both sides of the lower mold 3, and two groups of positioning skeleton slider cylinders 5 are respectively fixedly installed on the surfaces of the two groups of cylinder seats, and one end of the piston rod of the positioning skeleton slider cylinder 5 is movably connected to one side of the skeleton positioning movable block 6, so that the middle skeleton positioning movable block 6 is pushed to be located in the middle of the mold cavity of the lower mold 3 through the extension and retraction of the piston rods of the two groups of positioning skeleton slider cylinders 5.

[0023] An opening for pouring is reserved on one end surface of the lower mold 3 , and the opening is located on the end surface of the lower mold 3 away from the hinge 7 .

[0024] Working principle: When the utility model is used, the upper mold 1 is opened or closed on the lower mold 3 through the production line mold frame, and the flip block cylinder 4 pushes the lower mold flip block 2 to open and flip to disengage from the lower mold 3 or close on the lower mold 3. When pouring, the lower mold flip block 2 is closed on the lower mold 3 and closed with the lower mold 3, and the foam is injected from the opening on the surface of one end of the lower mold 3. After the injection is completed, the upper mold 1 is closed, and the product begins to foam. After the foaming is completed, the upper mold 1 is opened, and the flip block cylinder 4 pushes the lower mold flip block 2 to open, and the product is taken out manually. Compared with the previous mold structure, this structure is easier to exhaust gas, avoids the scrapping of sponge due to exhaust, improves production efficiency, and reduces the scrap rate.
