Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting molds, in particular to a plate die-casting mold which is easy to demould. Background Art

[0002] Die casting is a pressure casting method that uses a pressure casting machine (i.e., a die casting machine) equipped with a specific casting mold to heat metals such as copper, zinc, aluminum, or aluminum alloys to a liquid or semi-liquid state, and then pour them into the inlet of the die casting machine. Through the die casting process, copper, zinc, aluminum, or aluminum alloy parts that meet the requirements are cast.

[0003] A die-casting mold is required for die-casting of plates. Molten metal is injected into the mold. Through the die-casting method, a formed plate can be obtained after the molten metal cools. In order to make the plate demolding smoother, a release agent needs to be sprayed into the inside of the mold before die-casting. Although the existing die-casting mold can perform basic die-casting functions, the formed plate is not easy to demold and removed, which slows down the production progress. In addition, when spraying the release agent, the internal plate needs to be taken out first, and then the release agent is sprayed. It cannot be done at the same time, so the release agent spraying step affects the processing and production efficiency of the plate, so it needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems. The utility model provides a plate die-casting mold that is easy to demould, which has the advantages of easy demoulding and fast spraying of a release agent.

[0005] The top of the working table is fixed with a lower mold, and the bottom end of the lower mold is movably sleeved with an ejector plate. The bottom of the ejector plate passes through the lower mold and the working table and is movably sleeved with the inner wall of the working table. The bottom of the ejector plate is fixedly connected with a nozzle, and the bottom of the nozzle is fixedly connected with a fixed tube. The bottom of the fixed tube is fixedly installed with a hose. The bottom surface of the fixed tube is fixedly sleeved with a lifting plate. A slide groove is provided on the front of the lifting plate. A motor is fixedly installed on the front side of the bottom of the working table, and the other end of the motor output shaft is fixedly connected to a rotating shaft. The outer surface of the rotating shaft is fixedly sleeved with a disc, and the bottom end of the disc is fixedly sleeved with a round block. The rear end of the round block extends to the inside of the slide groove and is movably connected with the inner wall of the slide groove.

[0006] As a preferred embodiment of the present invention, a water pump is fixedly installed on the right side of the bottom of the workbench, the left side of the water pump is fixedly connected to the right end of the hose, and the bottom of the water pump is fixedly connected to a water inlet pipe.

[0007] As a preferred embodiment of the present invention, limit rods are movably sleeved on the left and right sides of the inner back of the lifting plate, and the top of the limit rods is fixedly connected to the bottom of the workbench.

[0008] As a preferred embodiment of the present invention, pneumatic cylinders are fixedly installed at the four corners of the top of the workbench, the top of the pneumatic cylinders is fixedly connected to a top plate, and the bottom of the top plate is fixedly installed with an upper mold.

[0009] As a preferred embodiment of the present invention, fixed blocks are fixedly installed inside the left and right ends of the lower mold, a second spring is fixedly installed on the top of the fixed block, a round plate is fixedly connected to the top of the second spring, and round rods are fixedly installed on the front and rear sides of the fixed block, and the other end of the round rod is fixedly connected to the inner wall of the lower mold.

[0010] As a preferred embodiment of the present invention, a moving block is movably sleeved on the outer surface of the round rod, a first spring is fixedly connected to the outer surface of the moving block, the other end of the first spring is fixedly connected to the inner wall of the lower mold, and a hinged rod is hinged inside the top end of the moving block.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model is provided with an ejector plate, a nozzle, a lifting plate and a motor. After the plate is die-cast, the operator can start the motor to make the rotating shaft drive the disc to rotate, so that the round block squeezes and pushes the inner surface of the slide, thereby driving the lifting plate to move upward, and then making the nozzle and the ejector plate move upward, so that the ejector plate ejects the formed plate upward.

[0036] The working principle and use process of this utility model:

[0037] The operator pours the molten metal into the interior of the lower mold 2, and then starts the pneumatic cylinder 16, so that the pneumatic cylinder 16 drives the top plate 17 and the upper mold 18 to move downward, thereby die-casting the plate. When the top plate 17 moves downward, it will push the buffer block 24 to move downward, so that the buffer block 24 pushes the two moving blocks 21 along the outer surface of the round rod 20 through the hinge rod 23 to move toward each other, thereby stretching the first spring 22. At this time, the first spring 22 will pull the moving block 21 outward under the action of elastic recovery, thereby making the hinge rod 23 It can push the buffer block 24 upward, thereby playing a buffering role for the top plate 17.

[0038] When the die-casting of the plate is completed, the motor 9 can be started to make the rotating shaft 10 drive the disc 11 to rotate, so that the round block 12 can rotate with the rotating shaft 10 as the axis, and then the round block 12 can squeeze and push the inner surface of the slide groove 8, thereby driving the lifting plate 7 to rise steadily along the inner surface of the limit rod 15. At this time, the lifting plate 7 will drive the fixed tube 5, the nozzle 4 and the ejector plate 3 upward, so that the ejector plate 3 pushes the plate to rise, and then demold the plate. When the nozzle 4 rises and enters the interior of the lower mold 2, the operator starts the water pump 13 at this time, so that the water inlet pipe 14 sucks the release agent, and sprays it out from the nozzle 4 through the hose 6 and the fixed tube 5, so that the release agent can be sprayed into the interior of the lower mold 2 while demolding the plate, thereby improving production efficiency.
