Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to a rapid injection mold for plastic products. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool for endowing plastic products with a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some parts with complex shapes. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, a formed product is obtained.

[0003] In the existing technology, the draw hook is an essential step during the molding of an injection mold. However, when the draw hook pulls the sprue plate, the main thing that blocks the sprue plate is the spring. But the spring is prone to losing its elasticity after long-term use, resulting in the draw hook being blocked. At the same time, the connection method between the sprue plate and the draw hook still uses a spring for fixation, which easily causes the spring to lose its elasticity, resulting in the draw hook being unable to pull out the sprue plate and affecting the operation of the plastic mold. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rapid injection mold for plastic products to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid injection mold for plastic products, including a main body, the main body is composed of a fixing mechanism, a connecting mechanism, a sprue plate, a draw hook, and a hydraulic mechanism. The fixing mechanism is connected to the sprue plate, the sprue plate is connected to the connecting mechanism, the hydraulic mechanism is connected to the sprue plate, the hydraulic mechanism is connected to the draw hook. The fixing mechanism is provided with a sliding groove, and a connecting rod is arranged in the sliding groove. The connecting rod is connected to the sprue plate. A fixing chamber is arranged inside the sprue plate, and the hydraulic mechanism is located in the fixing chamber. The connecting mechanism is provided with a connecting block, and a connecting groove is arranged on the connecting block. The draw hook is provided with a fixing rod connected to the sprue plate. The hydraulic mechanism includes a hydraulic pipe, a hydraulic groove, and an insertion rod. The insertion rod is located in the hydraulic groove and the insertion rod is connected to the connecting groove. The hydraulic pipe is connected to the hydraulic groove and the hydraulic mechanism. The hydraulic mechanism is located on both sides of the fixing rod.

[0006] Preferably, a fixing bearing is arranged on the fixing rod to connect the draw hook.

[0007] Preferably, a connecting thread is arranged on the fixing rod to connect the sprue plate.

[0008] Preferably, a push plate is arranged in the hydraulic groove to connect the insertion rod.

[0009] Preferably, a fixing block is arranged on the connecting rod and is located in the sliding groove.

[0010] Preferably, a fixing thread is arranged on the connecting rod to connect the sprue plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By installing a hydraulic mechanism and a connecting mechanism, the present utility model effectively solves the problem that the blocking spring of the water inlet plate is prone to losing elasticity and affecting the plastic mold. First, the hook device changes the traditional form of using a spring to block the water inlet plate to a hydraulic mechanism for blocking, which can effectively maintain the fixation and detachment of the water inlet plate. Then, by installing the hydraulic mechanism in the fixing chamber of the water inlet plate and connecting the bottom of the hydraulic mechanism to the hook, when pulling out the water inlet plate, by stopping the input of hydraulic fluid into the hydraulic groove by the hydraulic mechanism, the insertion rod loses the driving force and retracts out of the connecting groove and into the hydraulic groove, and then the water inlet plate can be pulled out by pulling the hook, thus realizing the detachment of the water inlet plate and the connecting mechanism.

[0013] 2. By changing the connection form between the water inlet plate and the hook, the present utility model effectively solves the problem that the connection between the water inlet plate and the hook is prone to detachment. The device still changes the connection form between the water inlet plate and the hook and changes the connection method between the hook and the water inlet plate. By setting a fixing rod on the hook to connect the water inlet plate, a fixing bearing is provided at the connection position between the fixing rod and the hook, which is convenient for the fixing rod to be rotatably connected to the water inlet plate on the hook. At the same time, the connecting thread provided on the fixing rod is inserted into the water inlet plate for fixation, which is convenient for the connection between the water inlet plate and the hook and will not cause the detachment of the hook and the water inlet plate. At the same time, the connection method between the hook and the water inlet plate is convenient for disassembly and connection, and is easy to use. Description of the Drawings

A fixing rod 51 is provided on the hook 5 to connect the sprue plate 4. The hydraulic mechanism 6 includes a hydraulic pipe 61, a hydraulic groove 62 and an insertion rod 63. The insertion rod 63 is located in the hydraulic groove 62 and the insertion rod 63 is connected to the connecting groove 311. The hydraulic pipe 61 is connected to the hydraulic groove 62 and the hydraulic mechanism 6. The hydraulic mechanism 6 is located on both sides of the fixing rod 51.

[0020] A fixing bearing 511 is provided on the fixing rod 51 to connect the hook 5, which can enable the fixing rod 51 to be rotatably connected to the sprue plate 4;

[0021] A connecting thread 512 is provided on the fixing rod 51 to connect the sprue plate 4, which can enable the hook 5 to be fixedly connected to the sprue plate 4;

[0022] A push plate 621 is provided in the hydraulic groove 62 to connect the insertion rod 63, which can push the insertion rod 63 to move left and right in the hydraulic groove 62;

[0023] A fixing block 221 is provided on the connecting rod 22 and is located in the chute 21, which can prevent the connecting rod 22 from sliding up and down and falling off in the chute 21;

[0024] A fixing thread is provided on the connecting rod 22 to connect the sprue plate 4, which can enable the fixing mechanism 2 and the sprue plate 4 to be fixedly connected.

[0025] Working principle: When the utility model is in use, the device changes the traditional nozzle plate 4 and the connecting mechanism 3 from the spring blocking to the hydraulic mechanism 6 blocking, and at the same time changes the connection form of the nozzle plate 4 and the hook 5 to facilitate the long-term operation of the injection mold and maintain the working life. First, the hydraulic mechanism 6 is installed in the fixed chamber 41 of the nozzle plate 4, and the bottom of the hydraulic mechanism 6 is connected to the hook 5. When the nozzle plate 4 is blocked, the hydraulic fluid is input into the hydraulic groove 62 through the hydraulic mechanism 6, and the hydraulic groove 62 pushes the push plate 621 to insert the insertion rod 63 into the connection groove 311 to achieve the blocking of the nozzle plate 4. When the nozzle plate 4 is pulled out, the hydraulic fluid is stopped from being input into the hydraulic groove 62 through the hydraulic mechanism 6, and the insertion rod 63 loses the pushing force. The force retracts the disengaged connection groove 311 and enters the hydraulic groove 62. Then, the nozzle plate 4 can be pulled out by pulling the hook 5 to realize the disengagement of the nozzle plate 4 and the connecting mechanism 3. Then, the connection method of the hook 5 and the nozzle plate 4 is changed, and the nozzle plate 4 is connected by setting a fixing rod 51 on the hook 5. A fixed bearing 511 is provided at the connection position of the fixing rod 51 and the hook 5, which is convenient for the fixing rod 51 to rotate on the hook 5 to connect the nozzle plate 4. At the same time, the connecting thread 512 on the fixing rod 51 is inserted into the nozzle plate 4 for fixing, which is convenient for the connection between the nozzle plate 4 and the hook 5. The disengagement phenomenon of the hook 5 and the nozzle plate 4 will not occur. At the same time, the connection method of the hook 5 and the nozzle plate 4 is convenient for disassembly and connection, and is easy to use. The operation is completed.
