Description

Technical Field

[0001] This utility model relates to the technical field of molds for producing plastic diaphragm filter plates, specifically a mold for producing plastic diaphragm filter plates with good sealing performance. Background Technology

[0002] Molds used in the production of plastic diaphragm filter plates are core tools for manufacturing diaphragm filter plates, a key component of filter presses.

[0003] Currently, plastic diaphragm filter plates are produced using injection molds. When demolding after injection molding, the molded part may stick to the upper mold and move with it. If the molded part falls during the movement, it may cause the plastic diaphragm filter plate to fall and be damaged, which has certain drawbacks. To address this, we propose a mold with good sealing properties for the production of plastic diaphragm filter plates. Utility Model Content

[0004] The purpose of this invention is to provide a mold for producing plastic diaphragm filter plates with good sealing performance, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing plastic diaphragm filter plates with good sealing performance, comprising a base plate, an upper mold, a lower mold, and a hydraulic cylinder. A guide rod is fixed to the top of the base plate, the guide rod passes through a sliding plate and is slidably connected to the sliding plate, a top plate is fixed to the top of the guide rod, a hydraulic cylinder is provided at the bottom of the top plate, a bracket is fixed to the output shaft of the hydraulic cylinder, the bracket is fixed to the top of the sliding plate, the upper mold is provided at the bottom of the sliding plate, the lower mold is provided at the top of the base plate, and a lifting assembly is provided at the top of the base plate.

[0006] The lifting component includes:

[0007] Support rods are used to lift injection molded parts that are attached to the upper mold.

[0008] The control component is used to control the movement of the support rod;

[0009] The abutment is used to control the return of the support rod;

[0010] The connecting spring is used to provide the force for the support rod to return to its original position.

[0011] The fixing plate is used to support the connecting spring.

[0012] Preferably, the control component includes a vertical rod, the bottom of which is fixed to the top of the base plate. A spiral groove is formed on the outer wall of the vertical rod. The vertical rod passes through a sliding plate and a slider. The top of the slider is fixed to the bottom of the sliding plate. A gear is rotatably mounted on the inner wall of the slider. A through hole is formed in the center of the gear. A sliding rod is fixed inside the through hole. The end of the sliding rod away from the gear is inserted into the inner side of the spiral groove. The gear meshes with a rack. The rack passes through a support rod near the slider and is slidably connected to the support rod. A return spring is fixed to the inner wall of the support rod. The end of the return spring away from the support rod is fixed to the rack. A fixing rod is fixed to the right side of the rack. The fixing rod passes through the sliding gear and is slidably connected to the sliding... The sliding connection uses a toothed joint. A tension spring is fixed to the right side of the sliding tooth. The end of the tension spring away from the sliding tooth is fixed to a fixed rod. When the slide plate moves downward, the slide plate moves downward with the slider, and the slider moves downward with the gear. At this time, the slide rod slides in the spiral groove on the outer wall of the vertical rod, causing the gear to rotate. The rack meshing with the gear moves the support rod away from the center of the slide plate, thus not affecting the normal closure between the upper and lower molds. When the rack and the sliding tooth mesh with the gear, the gear pushes the sliding tooth to move closer to the rack. Under the action of the tension spring, the sliding tooth moves back and forth, so that the sliding tooth always remains meshed with the gear. This ensures that even if the gear continues to rotate, the support rod cannot continue to move, avoiding jamming.

[0013] Preferably, the abutting component includes a connecting groove, which is formed at the bottom of the rack. An L-shaped rod is slidably mounted on the inner wall of the slider, and the top of the L-shaped rod is inserted into the inner side of the connecting groove. An abutting rod is hinged to the side of the L-shaped rod near the vertical rod. When the slider moves up or down, the abutting rod slides with the slider to the position of the spiral groove, where it is abutted by the spiral groove. As the slider continues to move, the abutting rod is abutted and folds, causing it to push the L-shaped rod to move away from the vertical rod. The vertical rod then moves along with the rack, disengaging the rack from the gear. At this time, the support rod can move to the side closer to the center of the slide plate under the action of the connecting spring to reset. This allows the support rod to move to the bottom of the upper mold to support the injection molded part when the upper and lower molds are separated for demolding, preventing the injection molded part from sticking to the bottom of the upper mold and falling and breaking as the upper mold moves.

[0014] Preferably, the support rod passes through the slider and is slidably connected to the slider. A fixing plate is fixed to the front of the slider. A connecting spring is fixed to the side of the fixing plate near the center of the slide plate. The end of the connecting spring away from the fixing plate is fixed to the connecting spring. When the support rod is not restricted, the support rod can be reset under the action of the connecting spring.

[0015] Compared with the prior art, this utility model provides a mold for producing plastic diaphragm filter plates with good sealing performance, which has the following beneficial effects:

[0016] 1. The mold for producing plastic diaphragm filter plates with good sealing performance, through the set support component, when the injection molding is completed and cooling is required for demolding, only the hydraulic cylinder is controlled to drive the slide plate to move upward. The rack and gear are disengaged by the contact component. At this time, the support rod can move to the side closer to the center of the slide plate under the action of the connecting spring. When the upper mold and lower mold are separated for demolding, the support rod can move to the bottom of the upper mold to support the injection molded part, avoiding the injection molded part from sticking to the bottom of the upper mold and falling and breaking as the upper mold moves.

[0017] 2. The mold for producing plastic diaphragm filter plates with good sealing performance, through the set control components, when the slide plate moves downward, the slide plate moves downward with the slider, and the slider moves downward with the gear. At this time, the slide rod slides in the spiral groove on the outer wall of the vertical rod, causing the gear to rotate. The rack that meshes with the gear moves the support rod to the side away from the center of the slide plate, so as not to affect the normal closure between the upper and lower molds.

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a mold for producing plastic diaphragm filter plates with good sealing performance, including a base plate 1, an upper mold 2, a lower mold 5, and a hydraulic cylinder 6. A guide rod 7 is fixed to the top of the base plate 1. The guide rod 7 passes through the slide plate 8 and is slidably connected to the slide plate 8. A top plate 9 is fixed to the top of the guide rod 7. A hydraulic cylinder 6 is provided at the bottom of the top plate 9. A bracket 4 is fixed to the output shaft of the hydraulic cylinder 6. The bracket 4 is fixed to the top of the slide plate 8. The bracket 4 allows the hydraulic cylinder 6 to apply force to six points on the top of the slide plate 8 simultaneously, ensuring a more stable splicing of the upper mold 2 and the lower mold 5 and improving the sealing performance of the mold. The upper mold 2 is located at the bottom of the slide plate 8, and the lower mold 5 is located at the top of the base plate 1. A lifting assembly 3 is provided at the top of the base plate 1. The lifting assembly 3 includes: a support rod 31, a control component 32, an abutment component 33, a connecting spring 34, and a fixing plate 35.

[0025] The control component 32 includes a vertical rod 321, the bottom of which is fixed to the top of the base plate 1. A spiral groove 322 is formed on the outer wall of the vertical rod 321. The vertical rod 321 passes through the slide plate 8 and the slider 323. The top of the slider 323 is fixed to the bottom of the slide plate 8. A gear 324 is rotatably mounted on the inner wall of the slider 323. A through hole is formed in the center of the gear 324. A slider 325 is fixed inside the through hole in the center of the gear 324, and the slider 325 is located away from the gear 324. One end of gear 24 is inserted into the inner side of the spiral groove 322. Gear 324 meshes with rack 326. Rack 326 passes through the support rod 31 near the slider 323 and is slidably connected to the support rod 31. A return spring 327 is fixed to the inner wall of the support rod 31. The end of the return spring 327 away from the support rod 31 is fixed to rack 326. A fixing rod 328 is fixed to the right side of rack 326. The fixing rod 328 passes through sliding tooth 329 and is slidably connected to sliding tooth 329. A tension spring 3210 is fixed to the right side of 9. The end of the tension spring 3210 away from the sliding tooth 329 is fixed to the fixed rod 328. When the slide plate 8 moves downward, the slide plate 8 moves downward with the slider 323. The slider 323 moves downward with the gear 324. At this time, the slide rod 325 slides in the spiral groove 322 on the outer wall of the vertical rod 321, causing the gear 324 to rotate. The rack 326, which meshes with the gear 324, moves the support rod 31 to the side away from the center of the slide plate 8, so as not to affect the normal closing between the upper mold 2 and the lower mold 5. When the rack 326 meshes with the sliding tooth 329 and the gear 324, the gear 324 pushes the sliding tooth 329 to the side closer to the rack 326. Under the action of the tension spring 3210, the sliding tooth 329 moves back and forth, so that the sliding tooth 329 always remains in the state of meshing with the gear 324, so that even if the gear 324 continues to rotate, the support rod 31 cannot continue to move, avoiding jamming.

[0026] The abutting element 33 includes a connecting groove 331, which is located at the bottom of the rack 326. An L-shaped rod 332 is slidably mounted on the inner wall of the slider 323. The top of the L-shaped rod 332 is inserted into the inner side of the connecting groove 331. An abutting rod 333 is hinged to the side of the L-shaped rod 332 near the vertical rod 321. When the slider 323 moves up or down, the abutting rod 333 slides with the slider 323 to the position of the spiral groove 322, where it is abutted by the spiral groove 322. As the slider 323 continues to move, the abutting rod 333... When the contact rod is pushed, it flips over, causing the contact rod 333 to push the L-shaped rod 332 to move away from the vertical rod 321. The vertical rod 321 can then move along with the rack 326, causing the rack 326 to disengage from the gear 324. At this time, the support rod 31 can move to the side closer to the center of the slide plate 8 under the action of the connecting spring 34, so that when the upper mold 2 and the lower mold 5 are separated for demolding, the support rod 31 can move to the bottom of the upper mold 2 to support the injection molded part, preventing the injection molded part from sticking to the bottom of the upper mold 2 and falling and breaking as the upper mold 2 moves.

[0027] The support rod 31 passes through the slider 323 and is slidably connected to the slider 323. A fixing plate 35 is fixed on the front of the slider 323. A connecting spring 34 is fixed on the side of the fixing plate 35 near the center of the slide plate 8. The end of the connecting spring 34 away from the fixing plate 35 is fixed to the connecting spring 34. When the support rod 31 is not restricted, the support rod 31 can be reset under the action of the connecting spring 34.

[0028] In this invention, during use, the hydraulic cylinder 6 is activated to control the slide plate 8 to move the upper mold 2 downwards. As the slide plate 8 moves downwards, it also moves the slider 323 downwards. The slider 323 moves the gear 324 downwards. At this time, the slide rod 325 slides in the spiral groove 322 on the outer wall of the vertical rod 321, causing the gear 324 to rotate. The rack 326, which meshes with the gear 324, moves the support rod 31 to the side away from the center of the slide plate 8, so as not to affect the normal closing between the upper mold 2 and the lower mold 5.

[0029] After the upper mold 2 and lower mold 5 are closed, injection molding can be performed. When demolding is required after the injection molding is completed and cooled, simply control the hydraulic cylinder 6 to drive the slide plate 8 to move upward. The slide plate 8 moves the upper mold 2 upward, and the slide plate 8 moves the slider 323 upward together. When the abutment rod 333 moves to the position of the spiral groove 322, the abutment rod 333 is abutted by the spiral groove 322. As the slider 323 continues to move, the abutment rod 333 is abutted and flipped, causing the abutment rod 333 to push the L-shaped rod 332 away from the vertical. When one side of rod 321 moves, the vertical rod 321 moves along with the rack 326, causing the rack 326 to disengage from the gear 324. At this time, the support rod 31 can move to the side closer to the center of the slide plate 8 under the action of the connecting spring 34, so that when the upper mold 2 and the lower mold 5 are separated for demolding, the support rod 31 can move to the bottom of the upper mold 2 to support the injection molded part, preventing the injection molded part from sticking to the bottom of the upper mold 2 and falling and breaking as the upper mold 2 moves. The staff can then pick up the injection molded part.

[0030] 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.
