Description

A rapid ejection device for a conical air duct forming mold Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a rapid ejection device for a conical air duct forming mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, and automated operation.

[0003] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. Most fans in the current technology are equipped with a conical air guide duct to guide the airflow. During the injection molding process of the air guide duct, the conical air guide duct needs to be ejected. In the current technology, the air guide duct injection mold does not fix the conical air guide duct after the air guide duct is injection molded. When ejecting the air guide duct, the air guide duct is prone to shaking, causing the air guide duct to collide and resulting in low practicality. Summary of the Invention

[0004] This utility model provides a quick ejection device for a conical air duct forming mold, which solves the problem that in the prior art, after the air duct injection mold is completed, the conical air duct structure is not fixed, and the air duct is prone to shaking when ejected, causing the air duct to collide and resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid ejection device for a conical duct forming mold includes a mounting base bolted to the bottom outer wall of the forming mold. An ejection mechanism is located below the mounting base. The ejection mechanism includes an ejection cylinder bolted to the bottom outer wall of the mounting base, a connecting plate bolted to the top of the piston rod of the ejection cylinder, and a mounting cylinder bolted to the top outer wall of the connecting plate. An extrusion assembly is located inside the mounting cylinder. The extrusion assembly includes a connecting rod, a first spring sleeved on the outer wall of the connecting rod, and a cross-shaped extrusion block. Four fixing components are located inside the mounting cylinder. Each fixing component includes a sliding rod that passes through and slides on the outer wall of the mounting cylinder, a fixing block welded to the outer wall of one end of the sliding rod, a second spring sleeved on the outer wall of the sliding rod, and a slider welded to the outer wall of one end of the sliding rod. Two limiting mechanisms are provided on the forming mold. Each limiting mechanism includes a limiting cylinder and a limiting block bolted to one end of the piston rod of the limiting cylinder.

[0007] Preferably, the molding die includes a fixed die, a movable die fitted inside the fixed die, and a mounting ring welded to the outer wall of the top of the movable die, wherein a fixing hole is formed on the outer wall of the mounting ring.

[0008] Preferably, the connecting plate is slidably sleeved on the lower inner wall of the fixed mold, and four limiting rods are bolted to the bottom outer wall of the connecting plate. The four limiting rods are respectively inserted through and slidably installed on the outer wall of the mounting base. An installation groove is opened on the bottom outer wall of the moving mold, and the mounting cylinder is slidably sleeved in the installation groove.

[0009] The above method involves moving the moving mold until it separates from the fixed mold, causing the piston rod of the ejector cylinder to move the connecting plate, thereby ejecting the conical air duct.

[0010] Preferably, a fixing opening is provided on the outer wall of the top of the mounting cylinder, and a limiting ring is fixed on the inner wall of the lower part of the fixing opening. The connecting rod is slidably sleeved in the limiting ring, and a mounting block is welded to the outer wall of the top of the connecting rod, and the mounting block is slidably sleeved in the fixing opening.

[0011] Preferably, the outer wall of the mounting cylinder has four limiting grooves, and the fixing block is slidably sleeved in the limiting grooves. One corner of the slider is provided with an inclined surface, and the inclined surface abuts against the outer wall of the extrusion block.

[0012] With the above scheme, the moving mold rises, causing it to break free from the pressure on the mounting block and connecting rod. Under the tension of the first spring, the mounting block is lifted, the connecting rod moves and drives the extrusion block to rise, and the extrusion block extrudes the four sliders, causing the four sliders to drive the four sliding rods and four fixed blocks to move respectively. The fixed blocks contact the lower inner wall of the conical air duct and fix the conical air duct.

[0013] Preferably, the upper outer wall of the fixed mold has two fixing grooves, and the limiting cylinder is connected to the inner wall of the fixing groove by bolts. The upper inner wall of the fixed mold has two channels, and the limiting block is slidably sleeved in the channel. One end of the limiting block abuts against the outer wall of the moving mold.

[0014] The above solution uses a limiting block to contact the moving mold, thereby limiting the conical air duct between the fixed mold and the moving mold and preventing the moving mold from carrying the conical air duct with it when it moves.

[0015] The beneficial effects of this utility model are as follows:

[0016] The moving mold rises, causing it to disengage from the pressure on the mounting block and connecting rod. Under the tension of the first spring, it lifts the mounting block, and the connecting rod moves, causing the extrusion block to rise. The extrusion block extrudes the four sliders, causing the four sliders to move the four sliding rods and four fixed blocks respectively. The fixed blocks contact the lower inner wall of the conical air duct and fix the conical air duct. This allows the conical air duct to be extruded and fixed, preventing it from shaking and bumping during extrusion, thus improving its practicality. Attached Figure Description
