A large sliding block structure of slurry tank

Abstract

This utility model relates to the field of mold technology, specifically a large slider structure for a slurry tank. It includes a large slider disposed inside a lower mold, and multiple ejector components disposed inside the lower mold. Each ejector component includes a gas strut, and multiple pressure components are disposed on the outer surface of the lower mold. Each pressure component includes a mounting plate, with an air chamber fixedly mounted on one side of the mounting plate, and an air pump fixedly mounted on the side of the air chamber located on the side surface of the mounting plate. In this utility model, by installing a gas strut below the large slider and applying pressure to its interior, the force required for the large slider to close the cavity is increased. Even when wear occurs on the guide surfaces of the inclined slider and the lower mold, and on the two key friction pairs of the inclined guide post and the inclined hole of the slider, multiple cavities can still be tightly closed, reducing flash caused by excessive gaps in the injection molded product and improving product molding accuracy and appearance quality.

Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a large slider structure for a slurry tank. Background Technology

[0002] The lithium battery slurry tank is a key container used for stirring and storing electrode slurry in the lithium battery production process. The slurry tank is usually produced by injection molding. Because the slurry tank has protruding structures on the sides, a slider structure needs to be set inside the mold to ensure smooth demolding of the slurry tank. The slider structure is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action. When the product structure makes it impossible for the mold to demold normally without the use of a slider, a slider structure must be used.

[0003] The existing slider structure relies on sliding friction for movement. The two key friction pairs, the guide surface between the inclined slider and the lower mold, and the inclined guide post and the inclined hole of the slider, will inevitably wear after long-term cyclic operation. Wear leads to an increase in the fit clearance, which may cause the movement to be stuck or not smooth. At the same time, the excessive clearance will allow the plastic melt to seep in, causing flash to be generated at the parting point of the injection molded product, affecting the dimensional accuracy and appearance quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide a large slider structure for a slurry tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A slurry tank large slider structure includes a large slider disposed inside the lower mold, and further includes:

[0007] Multiple ejector components are disposed inside the lower mold, and each ejector component includes a gas strut.

[0008] Multiple pressurizing components are disposed on the outer surface of the lower mold. Each pressurizing component includes a mounting plate. An air chamber is fixedly mounted on one side of the mounting plate, and an air pump is fixedly mounted on one side of the air chamber, which is located on the side surface of the mounting plate.

[0009] Furthermore, a slanted hole is provided on one side of the large slider, and a slanted guide rod is slidably inserted into the slanted hole. A slanted slider that is fixedly connected to the upper mold is fixedly installed on the upper end of the slanted guide rod, and a cavity is fixedly installed on the other side of the large slider.

[0010] Furthermore, the upper surface of the lower mold is provided with a groove below the large slider, and a first slider that is slidably connected to the groove is fixedly installed on the lower surface of the large slider. An installation hole is provided at one end of the groove, and the installation hole penetrates the outer surface of the lower mold.

[0011] Preferably, the gas strut moves through the mounting hole, and one end of the gas strut is fixedly connected to the first slider. A fixing seat is fixedly installed at one end of the outer surface of the gas strut. The fixing seat and the mounting plate are detachably connected to the lower mold by internal hex bolts.

[0012] Furthermore, both ends of the air chamber are fixedly connected to solenoid valves, and one of the solenoid valves is fixedly connected to the air port at one end of the air strut via a hose.

[0013] Preferably, a pressure sensor is screwed onto the upper end of the outer surface of the air chamber, an air inlet pipe is fixedly installed at the lower end of the outer surface of the air chamber, and the air outlet of the air pump is fixedly connected to the air inlet pipe through a flexible hose.

[0014] Preferably, a control box is fixedly mounted on one side surface of the mounting plate, and the control box is electrically connected to the air pump, pressure sensor and solenoid valve respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By operating the air pump, the air chamber is first pressurized. When the inclined guide rod is inserted into the inclined hole, high-pressure gas enters the air strut, giving the air strut an extension force, causing the large slider to slide. When the upper mold moves upward, both solenoid valves open, allowing the high-pressure gas to be discharged to the outside, so that the air strut can retract.

[0017] 2. When the large slider moves, the gas strut extends under the action of the pressure component, giving the first slider an auxiliary force in the same direction as the movement. This allows the large slider to move under the force of the inclined guide rod and the first slider in two directions, reducing the extrusion wear on the contact surface. At the same time, it increases the force when the large slider pushes the cavity to close. Even when the guide surface between the inclined slider and the lower mold, as well as the two key friction pairs between the inclined guide rod and the inclined hole, wear occurs, it can still ensure that multiple cavities are tightly closed, reducing the occurrence of flash due to excessive gaps in injection molded products, and improving the molding accuracy and appearance quality of the products.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a large slider structure for a slurry tank includes a large slider 101 disposed inside the lower mold 1. A slanted hole 103 is provided on one side of the large slider 101, and a slanted guide rod 105 is slidably inserted into the slanted hole 103. A slanted slider 104 fixedly connected to the upper mold is fixedly installed at the upper end of the slanted guide rod 105. A cavity 102 is fixedly installed on the other side of the large slider 101. The upper mold drives the slanted slider 104 to move downward, so that the slanted guide rod 105 is inserted into the slanted hole 103, pushing the large slider 101 to move. It also includes multiple push-acting components 2 disposed inside the lower mold 1. The push-acting components 2 include air struts 201. Multiple pressurizing components 3 are disposed on the outer surface of the lower mold 1. The pressurizing components 3 include a mounting plate 301. An air chamber 302 is fixedly installed on one side of the mounting plate 301. An air pump 305 is fixedly installed on one side of the air chamber 302 located on the side surface of the mounting plate 301.

[0025] Specifically, the gas strut 201 extends when the large slider 101 pushes the cavity 102 to move, and provides power through the pressurization component 3 to increase the force when the large slider 101 moves. When wear occurs on the contact surface, it reduces the possibility of the large slider 101 getting stuck. At the same time, it increases the force when multiple cavities 102 close, reducing the occurrence of gaps.

[0026] Example 1

[0027] like Figure 3 and Figure 4As shown, in this embodiment, both ends of the air chamber 302 are fixedly connected to a solenoid valve 303. One solenoid valve 303 is fixedly connected to the air port at one end of the air strut 201 through a hose. A pressure sensor 304 is screwed onto the upper end of the outer surface of the air chamber 302. The pressure sensor 304 detects the pressure inside the air chamber 302. An air inlet pipe 306 is fixedly installed at the lower end of the outer surface of the air chamber 302. The air outlet of the air pump 305 is fixedly connected to the air inlet pipe 306 through a hose.

[0028] In this embodiment, the air pump 305 operates, pumping outside air into the air chamber 302. At this time, the two solenoid valves 303 are closed, and the air strut 201 is in a retracted and stationary state. First, the air chamber 302 is pressurized. Then, when the inclined guide rod 105 is inserted into the inclined hole 103, the solenoid valve 303 connected to the air strut 201 opens, allowing high-pressure gas to enter the air strut 201 and giving it an extension force, causing the large slider 101 to slide. When the upper mold moves upward, both solenoid valves 303 open, allowing the high-pressure gas to be discharged to the outside, enabling the air strut 201 to retract. After the air strut 201 has retracted, the two solenoid valves 303 close, and pressurization continues to be applied to the air chamber 302, allowing the air strut 201 to complete its retraction and extension stroke.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, a groove 106 is provided on the upper surface of the lower mold 1 below the large slider 101. A first slider 108 is fixedly installed on the lower surface of the large slider 101 and slidably connected to the groove 106. A mounting hole 107 is provided at one end of the groove 106 and penetrates the outer surface of the lower mold 1. The gas strut 201 movably passes through the mounting hole 107, and one end of the gas strut 201 is fixedly connected to the first slider 108. A fixing seat 202 is fixedly installed at one end of the outer surface of the gas strut 201. The fixing seat 202 and the mounting plate 301 are detachably connected to the lower mold 1 by hexagonal bolts 307. The gas strut 201 and the pressure assembly 3 are fixed to the surface of the lower mold 1 by screwing the hexagonal bolts 307 into the threaded holes on the surface of the lower mold 1, which also facilitates the disassembly and maintenance of the gas strut 201 and the pressure assembly 3.

[0030] In practice, when the large slider 101 moves, the first slider 108 slides inside the groove 106. At this time, the gas strut 201 extends under the action of the pressure component 3, giving the first slider 108 an auxiliary force in the same direction as the movement. This causes the large slider 101 to move under the force of the inclined guide rod 105 and the first slider 108 in two directions, reducing the extrusion wear of the contact surface. At the same time, it increases the force when the large slider 101 pushes the cavity 102 to close. Even when the guide surface of the inclined slider 104 and the lower mold 1, as well as the two key friction pairs of the inclined guide rod 105 and the inclined hole 103, wear occurs, the multiple cavities 102 can still be tightly closed, reducing the occurrence of flash due to excessive gaps in the injection molded product, and improving the product molding accuracy and appearance quality.

[0031] like Figure 4 As shown, in this embodiment, a control box 308 is fixedly installed on one side surface of the mounting plate 301. The control box 308 is electrically connected to the air pump 305, the pressure sensor 304 and the solenoid valve 303 respectively.

[0032] In practice, a PLC controller is installed inside the control box 308. The pressure sensor 304 detects the pressure inside the air chamber 302 and transmits the signal to the PLC controller. The PLC starts and stops the air pump 305 and the solenoid valve 303 according to the pressure change, intermittently injecting and discharging air into the air strut 201.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
