Description

Technical Field

[0001] This utility model relates to the field of luggage manufacturing technology, specifically to a luggage injection mold. Background Technology

[0002] A luggage injection mold is a mold specifically used to produce plastic parts such as luggage shells. It is made by injecting molten plastic material into the mold cavity, cooling and solidifying it, and then demolding it to obtain the desired shape. The luggage is then assembled to obtain the luggage.

[0003] According to the Chinese patent announcement CN221212580U, "A Luggage Lid Processing Mold," the main description involves injecting a solution into the processing mold via an injection tube. When the luggage lid inside the processing mold needs to be separated after molding, the operating box is pulled backward to separate the luggage lid from the processing mold. Then, the handle is pulled backward to move the push plate synchronously, separating the push plate from the luggage lid. Then, the push plate is pushed in the opposite direction to separate the injection tube at one end of the connecting box from the luggage lid. The push plate is used for secondary demolding, which avoids the luggage lid from being too tightly adhered to the processing mold, making it impossible to demold manually by using tools, thus affecting subsequent operations and improving demolding efficiency.

[0004] After injection molding, the luggage lid needs to be demolded. At present, the main method is to use a robotic arm in conjunction with a pneumatic suction cup to pick up the molded luggage lid. Then, a release agent is sprayed on the inside of the mold to facilitate the next demolding. However, in some cases, residue will be generated in the mold during demolding, which will affect the subsequent demolding effect.

[0005] Therefore, a luggage injection mold is proposed to solve the problem that in some cases, residues will be generated during demolding, which will affect the subsequent demolding effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that in some cases, the mold will produce residues during demolding, which will affect the subsequent demolding effect. Therefore, a luggage injection mold is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a luggage injection mold, including a U-shaped frame, a fixed mold, an injection tube, and a moving mold. A hydraulic push rod is fixedly connected to one side of the U-shaped frame, and the output end of the hydraulic push rod is fixedly connected to the moving mold. A limit groove is opened on the bottom side of the U-shaped frame. A drive motor is fixedly connected to one side of the U-shaped frame located in the limit groove. A screw is fixedly connected to the output end of the drive motor. A moving block is threadedly connected to the screw. An air distribution pipe is fixedly connected to the upper end of the moving block. Nozzles are evenly fixedly connected to both sides of the air distribution pipe that are far apart from each other. An air pump is fixedly connected to one side of the U-shaped frame. A metal hose is fixedly connected to the output end of the air pump. The metal hose is fixedly connected to the moving block and communicates with the interior of the air distribution pipe.

[0008] As a preferred technical solution of this utility model, heat pipes are uniformly fixedly connected to both sides of the U-shaped frame. The heat pipes are connected to an external power source through wires. Contacts are uniformly fixedly connected to one side of the heat pipes. The contact points are movably inserted into the moving mold and the fixed mold respectively. By setting the heat pipes, the moving mold and the fixed mold can be heated, thereby forming preheating and improving the adhesion of the release agent.

[0009] As a preferred technical solution of this utility model, the U-shaped frame is fixedly connected to a support rod in the limiting groove, and a positioning block is sleeved on the support rod. The positioning block is sleeved on the metal hose. By setting the support rod and the positioning block, the metal hose can be connected, avoiding the scattered distribution of the metal hose.

[0010] As a preferred technical solution of this utility model, a spring is sleeved on the support rod, and the two ends of the spring contact the positioning block and the limiting groove respectively. By setting the spring, a force can be provided to maintain a certain pressure on the metal hose.

[0011] As a preferred technical solution of this utility model, a support ball is rotatably embedded on one side of the positioning block, and the support ball contacts the limiting groove. By setting the support ball, the friction between the positioning block and the limiting groove can be reduced.

[0012] This utility model has the following advantages: by setting a movable block between the fixed mold and the moving mold, along with an air distribution pipe and a nozzle, the mold groove can be cleaned under the action of an air pump. Furthermore, by connecting the moving mold and the fixed mold through heat pipes and contacts respectively, preheating can be provided, thereby improving the adhesion and spraying effect of the release agent and enhancing the injection molding effect.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The luggage injection mold shown includes a U-shaped frame 1, a fixed mold 2, an injection tube 3, and a movable mold 5. A hydraulic push rod 4 is fixedly connected to one side of the U-shaped frame 1. The hydraulic push rod 4 drives the movable mold 5 to move, enabling it to close with the fixed mold 2. When the mold is closed, the air distribution pipe 8 is located on both sides of the mold, without affecting the mold closing. The output end of the hydraulic push rod 4 is fixedly connected to the movable mold 5. A limit groove 6 is formed on the bottom side of the U-shaped frame 1. The limit groove 6 contacts the moving block 8. A drive motor is fixedly connected to one side of the U-shaped frame 1 at the limit groove 6. The drive motor drives the screw 7 to rotate, which can cause the moving block 8 to move at the limit. The drive motor output is fixedly connected to a screw 7, and a moving block 8 is threaded onto the screw 7. A distribution pipe 9 is fixedly connected to the upper end of the moving block 8. Spray nozzles 10 are evenly fixedly connected to the two sides of the distribution pipe 9 that are far apart from each other. The air pump 11 draws gas and supplies it to the spray nozzles 10 through the metal hose 12 and the distribution pipe 9, thereby blowing the mold grooves of the fixed mold 2 and the moving mold 5. The air pump 11 is fixedly connected to one side of the U-shaped frame 1. The output end of the air pump 11 is fixedly connected to the metal hose 12. The metal hose 12 is fixedly connected to the moving block 8 and communicates with the interior of the distribution pipe 9.

[0019] Both the fixed mold 2 and the moving mold 5 are movably connected to contact points 14, which are uniformly and fixedly connected to the heat pipe 13. An external power supply (not shown in the figure) is connected to the heat pipe 13 through a wire. The heat pipe 13 is fixedly connected to both sides of the U-shaped frame 1. By setting the heat pipe 13 and contact points 14, the moving mold 5 and the fixed mold 2 can be heated by connecting to electricity.

[0020] The metal flexible tube 12 is sleeved with the positioning block 16, the positioning block 16 is sleeved with the support rod 15, and the support rod 15 is fixedly connected in the limiting groove 6. The limiting groove 6 is located on the U-shaped frame 1. By setting the positioning block 16 to connect with the metal flexible tube 12, the metal flexible tube 12 can be limited, and the scattered distribution of the metal flexible tube 12 can be avoided, which would affect the movement of the moving block 8.

[0021] The limiting groove 6 and the positioning block 16 both contact the spring 17. The spring 17 is sleeved on the support rod 15. By setting the spring 17, a certain force can be provided to the metal hose 12, so that the metal hose 12 maintains a certain force during the movement of the moving block 8, and avoids scattering.

[0022] The limiting groove 6 contacts the support ball 18, and the support ball 18 rotates and is embedded in one side of the positioning block 16. By setting the support ball 18, the friction of the positioning block 16 movement can be reduced.

[0023] Working principle: When the injection molding is completed, the moving mold 5 and the fixed mold 2 separate to contact the two sides of the U-shaped frame 1. At this time, the contact 14 is inserted into the fixed mold 2 and the moving mold 5 respectively. The heat pipe 13 provides heating. At this time, the drive motor is started to drive the screw 7 to rotate and cause the moving block 8 to move. Then the air pump 11 draws gas to provide purging at the mold groove of the moving mold 5 and the fixed mold 2. Then the release agent is sprayed, which can improve the adhesion and spraying effect of the release agent, thereby improving the demolding effect.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
