Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with a cleaning function. 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, automated operation, a wide variety of colors and shapes, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] Long-term use of injection molds can easily lead to the accumulation of debris and slag around the mold, which can affect the molded parts. According to a published application for an injection mold with a cleaning function (publication number: CN218019869U), a second motor drives a bidirectional screw to rotate, which in turn drives a sliding plate to move. The sliding plate then drives a unidirectional screw to move between the moving mold and the fixed mold and reciprocate. A first motor then drives the unidirectional screw to rotate, which in turn drives a moving block to move. This allows a high-pressure jet nozzle to blow away impurities from the fixed mold and the moving mold, thus facilitating the next use of the injection mold.

[0004] However, when the above-mentioned injection mold is being cleaned, its moving block moves linearly back and forth at the position of the one-way screw. At this time, the high-pressure jet head also moves linearly back and forth, and its jet range is limited, resulting in insufficient cleaning of impurities on the fixed mold and moving mold, and poor cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold with a cleaning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold with a cleaning function, comprising a worktable, a fixed mold fixedly installed at the upper center of the worktable, a movable mold arranged above the fixed mold, vertical plates arranged at the left and right ends of the fixed mold, a sliding groove formed on the outer wall of the vertical plate, a drive motor fixedly installed on the front outer wall of the vertical plate, the output end of the drive motor passing through the vertical plate and fixedly connected to a bidirectional threaded rod, a threaded block threadedly connected to the outer wall of the bidirectional threaded rod, and a cleaning device arranged on the outer wall of the threaded block, the cleaning device comprising:

[0007] A fixed plate is fixedly installed on the outer wall of the right end of the threaded block. A reduction motor is fixedly installed on the right end of the fixed plate. The output end of the reduction motor passes through the fixed plate and the threaded block and is fixedly connected to the reciprocating lead screw.

[0008] A movable block is threadedly connected to the outer wall of a reciprocating lead screw. Connecting blocks are hinged to the upper and lower ends of the movable block. A high-pressure jet head is embedded and fixedly installed at the end of the connecting block away from the movable block. A telescopic spring is fixedly installed on the outer wall of the movable block. The end of the telescopic spring away from the movable block is fixedly connected to the connecting block.

[0009] A support rod is fixedly installed on the outer wall of the threaded block, and an extrusion block is fixedly installed on the support rod.

[0010] Preferably, the extrusion blocks are provided in multiple sets and arranged in an array.

[0011] Preferably, the connecting block is triangular and has an arc-shaped inclined surface at one end near the extrusion block. When the moving block moves on the outer wall of the reciprocating screw, its connecting block will come into contact with the extrusion block. The arc-shaped inclined surface of the connecting block comes into contact with the extrusion block, allowing the connecting block to swing and causing the high-pressure jet head to swing as well, thereby increasing the range of jetting and enhancing the cleaning effect.

[0012] Preferably, the left end of the reciprocating lead screw is rotatably connected to the guide block, the guide block is movable within the groove of the vertical plate, and a support rod is fixedly installed on the outer wall of the guide block.

[0013] Preferably, a guide rod is fixedly installed on the left end of the fixing plate, and the left end of the guide rod is fixedly connected to the guide block.

[0014] Preferably, a movable block is slidably connected to the outer wall of the guide rod, and the guide rod can limit and guide the movement of the movable block.

[0015] Compared with the prior art, this utility model provides an injection mold with a cleaning function, which has the following beneficial effects:

[0016] 1. This injection mold with cleaning function is equipped with a cleaning device. When the geared motor drives the reciprocating screw to rotate, the moving block on the outer wall of the reciprocating screw moves linearly back and forth. At the same time, the connecting block on the moving block also moves. During the movement, the connecting block comes into contact with the extrusion block and is squeezed, causing the connecting block to swing left and right on the outer wall of the moving block. At the same time, the high-pressure jet nozzle also swings, increasing its jetting range. In addition, when the high-pressure jet nozzle is in an inclined jetting position, it can better clean out debris and debris in the fixed mold and moving mold, improving the cleaning effect.

Detailed Implementation

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: an injection mold with a cleaning function, including a workbench 1, a fixed mold fixedly installed at the upper middle part of the workbench 1, a moving mold arranged above the fixed mold, vertical plates 2 arranged at the left and right ends of the fixed mold, a sliding groove opened on the outer wall of the vertical plate 2, a drive motor 201 fixedly installed on the front outer wall of the vertical plate 2, the output end of the drive motor 201 passing through the vertical plate 2 and fixedly connected to a bidirectional threaded rod 202, a threaded block 203 threadedly connected to the outer wall of the bidirectional threaded rod 202, a cleaning device 3 arranged on the outer wall of the threaded block 203, the cleaning device 3 including a fixing plate 301, the fixing plate 301 being fixedly installed on the right outer wall of the threaded block 203, the fixing plate A geared motor 302 is fixedly installed on the right end of 301. The output end of the geared motor 302 passes through the fixed plate 301 and the threaded block 203 and is fixedly connected to the reciprocating screw 303. A moving block 304 is threadedly connected to the outer wall of the reciprocating screw 303. A connecting block 305 is hinged to the upper and lower ends of the moving block 304. A high-pressure jet head 306 is embedded and fixedly installed at the end of the connecting block 305 away from the moving block 304. A telescopic spring 307 is fixedly installed on the outer wall of the moving block 304. The end of the telescopic spring 307 away from the moving block 304 is fixedly connected to the connecting block 305. A support rod 308 is fixedly installed on the outer wall of the threaded block 203. A pressing block 309 is fixedly installed on the support rod 308.

[0022] Specifically, the cleaning device 3 of this utility model includes a fixed plate 301, a reduction motor 302, a reciprocating screw 303, a moving block 304, a connecting block 305, a high-pressure jet nozzle 306, a telescopic spring 307, a support rod 308, and a pressing block 309. The reduction motor 302 drives the reciprocating screw 303 to rotate, and the moving block 304 on the outer wall of the reciprocating screw 303 moves linearly back and forth. When the moving block 304 moves, it drives the connecting block 305 to move as well. During the movement, the connecting block 305 comes into contact with the pressing block 309 and is compressed, causing the connecting block 305 to drive the high-pressure jet nozzle 306 to swing left and right, increasing its jet range and enhancing the cleaning effect.

[0023] In one embodiment of this utility model, when the drive motor 201 drives the bidirectional threaded rod 202 to rotate, the threaded blocks 203 on the outer wall of the bidirectional threaded rod 202 move in opposite directions, controlling the high-pressure jet head 306 to also move in opposite directions. The telescopic spring 307 can support the connecting block 305. When the connecting block 305 is squeezed by the squeezing block 309, the connecting block 305 rotates in the direction of the telescopic spring 307 and squeezes the telescopic spring 307. When the connecting block 305 is no longer in contact with the squeezing block 309, the telescopic spring 307 drives the connecting block 305 to reset, thereby allowing the connecting block 305 to swing back and forth, increasing the jet range of the high-pressure jet head 306. The drive motor 201, the bidirectional threaded rod 202, and the cleaning device 3 are arranged on the vertical plate 2 at the right end, while the guide block 4 is arranged on the vertical plate 2 at the left end.

[0024] Please continue reading. Figures 1-3 The extrusion blocks 309 are arranged in multiple sets in an array. The connecting block 305 is triangular and has an arc-shaped inclined surface at one end near the extrusion block 309. The left end of the reciprocating screw 303 is rotatably connected to the guide block 4. The guide block 4 is moved and connected in the groove of the vertical plate 2. A support rod 308 is fixedly installed on the outer wall of the guide block 4. A guide rod 5 is fixedly installed on the left end of the fixed plate 301. The left end of the guide rod 5 is fixedly connected to the guide block 4. A moving block 304 is slidably connected on the outer wall of the guide rod 5.

[0025] In the embodiments of this utility model, in order to facilitate and improve the cleaning effect of impurities and waste inside the moving mold and the fixed mold, the high-pressure jet head 306 is set to an inclined position. When the high-pressure jet head 306 sprays air in an inclined position, the impurities and waste inside the fixed mold can be better splashed out, thereby improving the cleaning effect.

[0026] During operation (or use), when cleaning of the fixed mold and moving mold is required, the drive motor 201 is started, causing the drive motor 201 to drive the bidirectional threaded rod 202 to rotate. This causes the threaded block 203 to drive the cleaning device 3 to slide in opposite directions, increasing the cleaning range. At this time, the reduction motor 302 is started, driving the reciprocating screw 303 to rotate. The moving block 304 on the outer wall of the reciprocating screw 303 moves linearly back and forth. When the moving block 304 moves, it also drives the connecting block 305 to move. During the movement, the connecting block 305 comes into contact with the extrusion block 309 and is squeezed, causing the connecting block 305 to rotate in the direction of the telescopic spring 307 and squeeze the telescopic spring 307. When the connecting block 305 is no longer in contact with the extrusion block 309, the telescopic spring 307 drives the connecting block 305 to return to its original position, causing the connecting block 305 to drive the high-pressure jet head 306 to swing left and right, increasing its jet range and enhancing the cleaning effect.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
