Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a time-delay slider mechanism for an injection mold. Background Art

[0002] Injection molds, also known as plastic molds, are mainly used for the molding of plastic products. This nickname intuitively reflects the main application areas of the mold. Injection molds can be used to give injection molded parts a specific shape, so that the shape of the injection molded parts can meet the needs of different products. Injection molds are needed when processing injection molded parts to shape the injection molding materials.

[0003] Injection molds are required when processing injection molded parts. Among them, the "slider mechanism of an injection mold" disclosed in the publication number "CN204054495U" has solved the problem that for some products with undercuts, a slider structure is often required for normal demolding. However, the traditional injection mold slider structure is a front mold side locking slider, which is easy to get stuck in the I-beam and has a large friction force, resulting in multiple technical disadvantages with great risks in the product production process.

[0004] However, there are still many defects in the actual use of injection molds with similar structures. For example, the device in the prior art is not convenient for improving the response speed of the slider, which makes the unloading of injection molded parts easily affected by the slider reset time, reducing the efficiency of using the device to process injection molded parts, and also narrowing the scope of application of the device, making it inconvenient to promote the use of the device. Therefore, a delayed slider mechanism for injection molds is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a time-delay slider mechanism for an injection mold to solve the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a time-delay slider mechanism for an injection mold, comprising a base plate, a plurality of limit rods fixedly mounted on the top of the base plate, a driving mechanism sleeved on the outer side of the limit rods, an upper mold base sleeved on the top of the outer side of the limit rods, and an auxiliary demoulding mechanism for demoulding the injection molded part fixedly mounted inside the upper mold base;

[0007] The driving mechanism includes a lower die base, cylinders are fixedly installed on both sides of the lower die base, a slider body is fixedly installed on the output end of the cylinder, a plurality of ejection members are equidistantly installed on the top of the slider body, a plurality of telescopic rods are fixedly installed on the top of the lower die base, a return spring is sleeved on the outer side of the telescopic rod, the bottom end of the return spring is fixedly connected to the outer side of the slider body, and a plurality of extended electric rods are equidistantly installed on the top of the lower die base;

[0008] The auxiliary demoulding mechanism includes an injection moulding base, and a plurality of cooling pipes are equidistantly installed inside the injection moulding base. One end of each cooling pipe is fixedly installed with a first solenoid valve pipe.

[0009] Preferably, a plurality of locking members are equidistantly installed on the top of the bottom plate, and a screw sleeve is sleeved on the top of each locking member.

[0010] Preferably, a plurality of movable sleeves are fixedly installed on the outside of the upper mould base. An elastic member is fixedly installed at the bottom of each movable sleeve, and a fixed sleeve is installed at the bottom of the elastic member. The fixed sleeve and the limiting rod are fixedly connected by welding.

[0011] Preferably, a cooling box is fixedly installed at one end of the first solenoid valve pipe. A cooling component extending out is fixedly installed inside the cooling box. A circulating pump is fixedly installed on one side of the cooling box through a pipe fitting, and a suction pipe is fixedly installed on the other side of the circulating pump.

[0012] Preferably, a transfer seat is fixedly installed at the top of the limiting rod, and a second solenoid valve pipe is fixedly installed at the top of the transfer seat.

[0013] Preferably, a protective shell is fixedly installed on the outside of the circulating pump, and one end of the suction pipe is fixedly connected to the other end of the cooling pipe.

[0014] Beneficial effects

[0015] The utility model provides a delay slider mechanism for an injection mould. Compared with the prior art, the following beneficial effects are achieved:

[0016] 1. When the electric rod is energized and runs, it drives the lower mould base to move vertically. The vertically moving lower mould base can contact the upper mould base and move synchronously to the bottom of the transfer seat for contact and closing for injection moulding. After the injection moulding is completed, the electric rod is energized and runs again to drive the lower mould base to move vertically, so that the contact force on the upper mould base disappears, and the upper mould base can be driven to reset by the high elasticity of the elastic member. The cylinder runs to drive the slider body to move vertically. The vertically moving slider body can drive the return spring to be elastically compressed through the telescopic rod, and the injection moulding part can be separated by the ejector part extending out of the lower mould base through the elastically compressed return spring, so as to achieve the purpose of delaying the ejection of the injection moulding part. Then, the telescopic rod can be driven to reset by the high elastic force of the return spring, thus shortening the reset time of the slider body, realizing the function of improving the processing efficiency of the injection moulding parts by the device, shortening the reset time of the ejector part, improving the processing efficiency of the injection moulding parts by the device, and facilitating the popularization and use of the device.

[0017] 2. The cooling component is energized to dissipate heat from the coolant stored inside the cooling box, and the first solenoid valve pipe is energized to transport the low-temperature refrigerant to the inside of the injection seat, so that the low-temperature refrigerant absorbs the heat generated by cooling the injection molded part through the cooling pipe. Then, the circulation pump is energized to suck the refrigerant that has absorbed heat inside the suction pipe. The suction pipe can suck the coolant flowing inside the cooling pipe and transport it to the inside of the cooling box for recycling, realizing the anti-sticking function of the device, avoiding the problem that the high-temperature injection molded part is easily stuck to the inside of the device, resulting in the need to stop the device for cleaning, and improving the reliable effect of using the device.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides two technical solutions:

[0025] The first implementation method: A time-delay slider mechanism for an injection mold, including a bottom plate 1. A plurality of limit rods 6 are fixedly installed on the top of the bottom plate 1. A driving mechanism 2 is sleeved on the outer side of the limit rods 6. A top mold base 3 is sleeved on the top of the outer side of the limit rods 6. An auxiliary demolding mechanism 4 for demolding the injection molded part is fixedly installed inside the top mold base 3;

[0026] The driving mechanism 2 includes a lower mold base 201. Two sides inside the lower mold base 201 are fixedly installed with cylinders 202. The output ends of the cylinders 202 are fixedly installed with slider bodies 203. A plurality of ejecting parts 204 are equidistantly installed on the top of the slider bodies 203. A plurality of telescopic rods 205 are fixedly installed on the top inside the lower mold base 201. A return spring 206 is sleeved on the outer side of the telescopic rods 205. The bottom end of the return spring 206 is fixedly connected to the outer side of the slider body 203. A plurality of extended electric rods 207 are equidistantly installed on the top inside the lower mold base 201;

[0027] The auxiliary demolding mechanism 4 includes an injection seat 401. A plurality of cooling pipes 402 are equidistantly installed inside the injection seat 401. One end of the cooling pipes 402 is fixedly installed with a first solenoid valve pipe 403. A plurality of locking parts 101 are equidistantly installed on the top of the bottom plate 1. A screw sleeve is sleeved on the top of the locking parts 101;

[0028] A plurality of movable sleeves 603 are fixedly installed on the outer side of the top mold base 3. A elastic member 602 is fixedly installed at the bottom of the movable sleeve 603. A fixed sleeve 601 is installed at the bottom of the elastic member 602. The fixed sleeve 601 is fixedly connected to the limit rod 6 by welding. A transfer seat 5 is fixedly installed at the top of the limit rod 6. A second solenoid valve pipe 501 is fixedly installed at the top of the transfer seat 5.

[0029] After being connected to external equipment through the second solenoid valve pipe 501, the raw material can be conveyed into the second solenoid valve pipe 501. The electric rod 207 is energized to drive the lower mold base 201 to move vertically. The vertically moving lower mold base 201 can abut against the top mold base 3 to move synchronously to the bottom of the transfer seat 5 for abutting and closing for injection molding operation. The injection molding raw material can be conveyed into the top mold base 3 through the second solenoid valve pipe 501 for injection molding;

[0030] After the injection molding operation is completed, the electric rod 207 is energized to drive the lower mold base 201 to move vertically, so that the abutting force on the top mold base 3 disappears, and the high elasticity of the elastic member 602 can drive the top mold base 3 to reset, which is convenient for the operator to remove the pouring port of the injection molded part;

[0031] The operation of the cylinder 202 drives the slider body 203 to move vertically. The slider body 203 that moves vertically can drive the return spring 206 to be elastically compressed through the telescopic rod 205. The elastically compressed return spring 206 can drive the ejector 204 to extend out of the lower mold base 201, thereby separating the injection molded part and achieving the purpose of delayed ejection of the injection molded part. The high elastic force of the return spring 206 can then drive the telescopic rod 205 to reset, thereby shortening the reset time of the slider body 203 and achieving the function of improving the efficiency of the device in processing injection molded parts.

[0032] By using the locking piece 101 in conjunction with the screw sleeve, the base plate 1 can be easily installed at the specified installation position, ensuring the stability of the installation position of the base plate 1. The moving upper mold base 3 can drive the movable sleeve 603 to move to a synchronous position, and the movable sleeve 603 that moves to a synchronous position can drive the elastic piece 602 to perform elastic stretching. When the resistance force on the upper mold base 3 disappears, the high elastic force of the elastic piece 602 can drive the upper mold base 3 to reset.

[0033] The second embodiment differs from the first embodiment primarily in that a cooling box 404 is fixedly mounted on one end of the first solenoid valve tube 403. An extended cooling assembly 405 is fixedly mounted within the cooling box 404. A circulating pump 406 is fixedly mounted on one side of the cooling box 404 via a pipe, and a suction pipe 407 is fixedly mounted on the other side of the circulating pump 406. A protective housing 7 is fixedly mounted on the outside of the circulating pump 406, and one end of the suction pipe 407 is fixedly connected to the other end of the cooling tube 402.

[0034] The protective shell 7 provides an installation position for the circulation pump 406, ensuring the stability of the installation position of the circulation pump 406 and preventing the circulation pump 406 from being knocked off due to external impact.

[0035] The cooling component 405 is powered on to dissipate heat and cool down the coolant stored in the cooling box 404, and the first solenoid valve tube 403 is powered on to transport the low-temperature coolant to the inside of the injection molding seat 401, so that the low-temperature coolant absorbs the heat generated by the cooling of the injection molded part through the cooling pipe 402, and then the circulating pump 406 is powered on to absorb the coolant in the suction pipe 407 after absorbing heat. The suction pipe 407 can absorb the coolant flowing in the cooling pipe 402 and transport it to the inside of the cooling box 404 for recycling, thereby realizing the function of preventing the device from sticking.
