Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a lifter mechanism provided with a travel switch. Background Art

[0002] The lifter mechanism is a commonly used mechanism in the design of injection molds, mainly used to solve the problem of difficult demolding of products in the mold due to the presence of undercuts, grooves or other structures that cannot be directly demolded from the main parting surface of the mold. The lifter mechanism makes these difficult-to-demold parts smoothly separate from the mold when the product is demolded by tilting.

[0003] Considering that the lifter rod needs to be driven by an oil cylinder, and the oil cylinder needs to control the stroke in cooperation with a travel switch, it is necessary to use a lifter mechanism provided with a travel switch for operation. For example, the Chinese patent publication number "CN210669339U" in the prior art discloses a lifter mechanism, including: a lifter rod; a lifter sleeve, a slot is opened in the lifter sleeve, and one end of the lifter rod is inserted into the slot; a guide slide sheet, which is movably hinged to opposite sides of the lifter sleeve; and a lifter seat, a chute is opened in the lifter seat, the lifter sleeve and the guide slide sheet are arranged in the chute, and the guide slide sheet cooperates with the chute for guiding and sliding. The lifter mechanism provided by the utility model has good guiding and sliding performance and good reliability.

[0004] Some lifter mechanisms do not elaborate on how to control the moving distance of the lifter rod. If the moving distance of the lifter rod cannot be accurately regulated, it will not only directly affect the dimensional accuracy of the product, but also cause the product size to be large or small due to the uncontrollable moving distance, affecting the product quality and having poor practicability. Summary of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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.

[0022] Referring to Figures 1-5 , an inclined ejector mechanism provided with a travel switch, including an inclined ejector base 1, a control unit is fixedly installed on the side of the inclined ejector base 1, and an inclined ejector mechanism 2 is arranged inside it. A pair of travel switches 4 are arranged on the top of the inclined ejector base 1 through a slide rail 3, and the travel switches 4 are electrically connected to the control unit;

[0023] Among them, an adjustment component 5 for adjusting the movement of the travel switch 4 is arranged in the slide rail 3, and the adjustment component 5 further includes a fixing part 6 for fixing the travel switch 4.

[0024] Furthermore, the inclined ejector mechanism 2 includes a movable seat 21 slidably connected inside the inclined ejector base 1. A mold base 22 is fixedly installed on the side of the movable seat 21, and a pair of inclined ejector rods 23 for demolding are arranged inside the mold base 22.

[0025] It should be added that a hydraulic cylinder is fixedly installed on the side of the movable seat 21. The output end of the hydraulic cylinder is fixedly connected to the movable seat 21. The inclined ejector rod 23 is slidably connected to the mold base 22 and fixedly connected to the movable seat 21;

[0026] Among them, when the hydraulic cylinder drives the movable seat 21 to move under the cooperation of the travel switch 4, the inclined ejector rod 23 moves relative to it, and then demolding is carried out. Moreover, because the telescopic distance of the output end of the hydraulic cylinder is different during the processing of different products, in order to accurately control the stroke, the position of the travel switch 4 needs to be adjusted.

[0027] Furthermore, the adjusting assembly 5 includes a sliding seat 51. A through groove penetrates through the bottom of the slide rail 3, and a sliding groove 52 is formed at the top thereof. A plurality of corresponding clamping grooves 53 are formed by extending both sides of the sliding groove 52. A pair of the sliding seats 51 are slidably connected in the through groove.

[0028] More specifically, a convex portion 54 is provided at the center of the inner wall top of the sliding seat 51, and unlocking members 55 are slidably connected to both sides. Limiting columns 56 are fixedly connected to both sides of the convex portion 54. The limiting columns 56 are slidably connected to the unlocking members 55, and springs 57 are sleeved at the ends. Both ends of the springs 57 are fixedly connected to the side surfaces of the convex portion 54 and the unlocking members 55 respectively. A clamping block 58 is provided at the bottom of the unlocking member 55. The clamping block 58 is slidably connected to the sliding groove 52 and is inserted into the clamping groove 53.

[0029] It is worth mentioning that under normal circumstances, the unlocking member 55 drives the clamping block 58 to abut against the clamping groove 53 under the elastic support of the spring 57, and then fixes the sliding seat 51 to achieve the effect of adjusting the position of the travel switch 4.

[0030] Generally speaking, the fixing member 6 includes a pair of guiding grooves 61 formed on the end face of the sliding seat 51. A T-shaped block 62 is provided at the top of the unlocking member 55. The T-shaped block 62 is slidably connected in the guiding groove 61. The travel switch 4 is fixedly installed in a fixing seat 63. A pair of T-shaped grooves 64 are oppositely arranged at the bottom of the fixing seat 63. The T-shaped block 62 is slidably connected in the T-shaped grooves 64.

[0031] Finally, a positioning bead 65 is fixedly installed on the side surface of the sliding seat 51. A clamping groove capable of being engaged with the positioning bead 65 is formed on the side surface of the unlocking member 55. A resisting rod 24 is fixedly connected to the top of the movable seat 21. The resisting rod 24 is arranged between a pair of the travel switches 4 and can abut against the travel switch 4.

[0032] It should be noted that when the unlocking member 55 moves and drives the T-shaped block 62 to move, and then moves under the action of the spring 57, it can drive the T-shaped block 62 to fix the fixing seat 63 through the T-shaped grooves 64;

[0033] Moreover, as Figure 4As shown, the length of the card slot 53 is approximately half of the length of the T-shaped slot 64. Moreover, the positioning glass bead 65 functions as a safeguard. Under normal circumstances, when the unlocking member 55 is pressed to the appropriate position, the positioning glass bead 65 will engage with the card slot. At this time, the clamping block 58 disengages from the card slot 53, while the T-shaped block 62 remains within the T-shaped slot 64. On the one hand, it reminds the operator that the unlocking member 55 has been unlocked. On the other hand, the fixing base 63 still cannot be disassembled in this state.

[0034] In addition, an opening is provided on the side of the fixing base 63, and the sensing end of the travel switch 4 is arranged at the opening and can be abutted by the abutting rod 24.

[0035] Working mode: During operation, a pair of unlocking members 55 are pressed simultaneously to drive the clamping block 58 to retract. After the clamping block 58 disengages from the card slot 53, the sliding seat 51 is pushed to move, achieving the function of adjusting the travel switch 4.

[0036] After the unlocking member 55 is released, under the action of the spring 57, the unlocking member 55 drives the clamping block 58 to be inserted into the card slot 53 to fix the travel switch 4.

[0037] Moreover, when the unlocking member 55 is unlocked, the card slot will engage with the positioning glass bead 65 at a suitable position to remind the operator that the sliding seat 51 can be adjusted. When the unlocking member 55 is continuously pressed, a pair of T-shaped blocks 62 disengage from the T-shaped slot 64, and then the fixing base 63 can be lifted out to replace the travel switch 4.

[0038] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
