Description

Technical Field

[0001] The utility model belongs to the technical field of dripper injection molding machines, in particular to a drip irrigation pipe dripper injection molding machine. Background Art

[0002] The dripper is the energy dissipation and water outlet facility of the drip irrigation system. Its function is to eliminate the residual energy of the pressurized water flow in the capillary tube and inject it into the soil evenly and slowly.

[0003] At present, when operators produce drip irrigation pipe drippers, they usually use related injection molding machines to quickly inject the dripper model. At present, when operators use injection molding machines, they usually use the upper mold and the lower mold to cooperate, and then put the injection liquid into the upper mold. However, when the operator stops production, the injection port is in an open state. At this time, a large amount of dust will enter the inside of the injection port. When the operator performs the next injection molding, the dust will greatly affect the quality of the injection molding, 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 drip irrigation pipe dripper injection molding machine, which has the advantage of shielding dust.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a drip irrigation pipe dripper injection molding machine comprises a table top, a lower mold is movably installed on the top of the table top, an upper mold is movably connected to the top of the lower mold, an injection port is opened on the top of the upper mold, limit plates are fixedly installed on the left and right sides of the top of the upper mold, a baffle plate is movably connected to the inner side of the limit plate, a fixing plate is fixedly installed on the front side of the limit plate, a first spring is fixedly installed on the left and right sides of the back side of the fixing plate, the other end of the first spring is fixedly connected to the front side of the baffle plate, a fixing frame is fixedly installed on the top of the limit plate, a card plate is movably connected to the inner side of the fixing frame, the bottom end of the card plate extends to the interior of the baffle plate and is movably connected to the interior of the baffle plate, a pull plate is fixedly installed on the front side of the card plate, a second spring is fixedly installed on the top of the card plate, and the other end of the second spring is fixedly connected to the top of the inner cavity of the fixing frame.

[0008] As a preferred embodiment of the present invention, both upper and lower sides of the movable plate are movably connected with mounting plates, and the inner sides of the mounting plates are fixedly connected to the left and right sides of the lower mold.

[0009] As a preferred embodiment of the utility model, limit frames are fixedly installed on both left and right sides of the lower mold, and the inner side of the limit frame is movably connected with a lifting block.

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

[0013] 1. The utility model sets a limit plate, a baffle plate, a first spring, a card plate and a second spring. The operator first pulls the pull plate, and the pull plate will move upward with the card plate under the limiting action of the fixed frame. At this time, the card plate will apply an extrusion force to the second spring and leave the inside of the baffle plate. At this time, the first spring will restore the elastic force to make the baffle plate move backward under the limiting action of the limit plate. At this time, the baffle plate will move to the top of the injection port. At this time, the baffle plate will have a shielding effect on the injection port and can also prevent dust from entering.

[0014] 2. The utility model sets a rectangular plate, a movable plate, a mounting plate, a lifting block and an inclined plate. Due to the design of the rectangular plate, the rectangular plate will cooperate with the movable plate to fix the lower mold and the upper mold to prevent shaking during the injection molding process, which will lead to poor injection molding quality. At this time, the operator pulls the pulling plate, and the pulling plate will move downward with the lifting block under the limit of the limit frame and apply extrusion force to the third spring. At this time, the lifting block will cause the inclined plate to rotate and pull the movable plate. At this time, the movable plate will move to the front side under the limit of the mounting plate. At this time, the movable plate will leave the inside of the rectangular plate, and the fixed relationship between the lower mold and the upper mold will be released.
