Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically, to a structure for needle extraction in the vertical direction of a slide. Background Technology

[0002] In the field of injection mold technology, traditional vertical pin-pulling structures for slides mostly adopt conventional movable pin designs, such as directly fixing the movable pin to the panel. When the mold opens, the movable pin is pulled out by moving the panel. However, in this structural layout, the opening distance is too large, and the movable pin will be completely pulled out of the slide. It is difficult to avoid the movable pin being damaged when the mold is closed before the slide is fully reset, resulting in a greater risk of the movable pin pressing on the slide when the mold is closed, which can easily affect production efficiency and product quality.

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This utility model embodiment provides a structure for needle extraction in the vertical direction of row positioning, such as... Figures 1 to 9 As shown, the structure for vertical needle extraction in the row position includes a support block 1 fixedly connected to the panel 100 and a movable block 2 movably connected to the row position 200. The movable block 2 is located below the support block 1. The upper end of the movable block 2 is provided with a rubber plug 3, the upper part of which is tightly inserted into the support block 1. The lower end of the movable block 2 is provided with an elastic reset member 4, which provides the movable block 2 with an elastic reset force in the vertical direction. A travel limit member 5 is inserted inside the movable block 2, the lower end of which protrudes from the lower end face of the movable block 2 and is fixedly inserted into the row position 200. A movable needle 6 is also connected to the movable block 2, the lower part of which is inserted into the row position 200 and moves synchronously with the movable block 2.

[0031] Furthermore, in this embodiment, the movable block 2 is provided with a snap-fit ​​mounting groove 20. The upper part of the movable pin 6 is adapted to snap into the snap-fit ​​mounting groove 20. The movable pin 6 is detachably connected to the movable block 2 through the snap-fit ​​mounting groove 20, which facilitates the replacement of the movable pin 6. The movable pin 6 includes a movable pin body 61 and a locking block 62 located at the upper end of the movable pin body 61. The movable pin body 61 is cylindrical in shape, and its diameter gradually decreases from top to bottom. The locking block 62 extends radially outward along the upper end face of the movable pin body 61. The locking block 62 is disc-shaped, and its diameter is larger than the diameter of the upper end face of the movable pin body 61. Both the upper part of the movable pin body 61 and the locking block 62 are adapted to snap into the snap-fit ​​mounting groove 20, making the operation simple.

[0032] Furthermore, in this embodiment, a protrusion 21 is provided on one outer side of the movable block 2, and a snap-fit ​​mounting groove 20 is provided on the protrusion 21. The protrusion 21 provides a suitable positional space for mounting the movable pin 6. Specifically, the snap-fit ​​mounting groove 20 consists of a receiving groove 201 and a locking slot 202 provided on the protrusion 21. The receiving groove 201 is located on the side of the protrusion 21 away from the movable block 2 and extends through the lower end face of the protrusion 21. The receiving groove 201 is adapted to the upper part of the movable pin body 61 and is used to receive the upper part of the movable pin body 61 and stably place it therein. The locking slot 202 extends inward along the inner wall surface of the receiving groove 201 on the side of the protrusion 21 away from the movable block 2. The locking slot 202 is adapted to the locking block 62 and is used to receive the locking block 62 and stably place it therein.

[0033] Furthermore, in this embodiment, a travel limiting groove 203 is provided at the center of the upper end face of the movable block 2, and a through hole 204 is provided on the inner bottom surface of the travel limiting groove 203, penetrating the lower end face of the movable block 2. The upper part of the travel limiting member 5 is located within the travel limiting groove 203 and does not protrude from the travel limiting groove 203, so as to limit the excessive upward movement of the movable block 2; the lower part of the travel limiting member 5 passes through the through hole 204 and partially protrudes from the through hole 204, so as to be fixedly inserted into the sliding position 200. Through the cooperation of the travel limiting groove 203 and the through hole 204 with the travel limiting member 5, the movable block 2 can move vertically and vertically relative to the travel limiting member 5.

[0034] The travel limiting component 5 is a plug screw. The diameter of the plug screw head is larger than the diameter of its shank. The head and part of the shank of the plug screw are located within the travel limiting groove 203, and the diameter of the travel limiting groove 203 is adapted to the head of the plug screw; the other part of the shank of the plug screw passes through the through hole 204, and the diameter of the through hole 204 is adapted to the other part of the shank of the plug screw; the lower end of the plug screw protrudes from the through hole 204.

[0035] Furthermore, in this embodiment, the upper surface of the movable block 2 is also provided with two first mounting holes 205, which are located on both sides of the travel limiting groove 203. A rubber plug 3 is fixedly installed in each of the two first mounting holes 205, with the upper part of each rubber plug 3 protruding from the corresponding first mounting hole 205 so that it can be tightly inserted into the lower surface of the support block 1. Correspondingly, the lower surface of the support block 1 is provided with two fixing holes 101, which are used for the upper parts of the two rubber plugs 3 to be tightly inserted. The upper surface of the support block 1 is provided with two screw holes 102, so that screws or other fasteners can be threaded into the screw holes 102 to achieve a fixed connection between the support block 1 and the panel 100.

[0036] The lower end face of the movable block 2 is provided with two second mounting holes 206, which are located on both sides of the through hole 204, and correspond one-to-one with the two first mounting holes 205. Each of the two second mounting holes 206 contains an elastic reset member 4, the lower part of which protrudes from the corresponding second mounting hole 206. The elastic reset member 4 is a spring.

[0037] like Figures 6 to 9 As shown, panel 100 is located above plate A 300, and slide 200 is located inside the lower part of plate A 300. Slide 200 has a corresponding recess for accommodating movable block 2. Correspondingly, plate A 300 has a clearance opening at a position corresponding to the recess, allowing movable block 2 to move smoothly upwards or downwards. When the lower part of movable block 2 is placed in the recess, the lower end of the locking screw is fixedly inserted into the inner bottom surface of the recess, and the lower ends of both springs abut against the inner bottom surface of the recess. When movable block 2 is no longer under the pressure of support block 1, the two springs allow movable block 2 to be held at a suitable height, thus keeping the movable pin 6 in the withdrawn state.

[0038] The working principle of the structure for vertical needle extraction in the sliding position according to this utility model embodiment is as follows: When the panel 100 and the A plate 300 are molded, since the support block 1 is fixed on the panel 100, the support block 1 moves upward. Under the action of the rubber plug 3, the support block 1 will drive the movable block 2 to move a certain distance. As the support block 1 continues to move, under the limiting action of the plug screw, the movable block 2 moves to a certain position and stops moving. The rubber plug 3 will detach from the support block 1, so that the movable block 2 is separated from the support block 1. After the movable block 2 is separated from the support block 1, under the action of the spring, the movable block 2 will be pushed up at the position limited by the plug screw. The movable block 2 remains stationary. Since the movable needle 6 is connected to the movable block 2, it can synchronously drive the movable needle 6 to pull away the undercut product but will not completely pull away from the sliding position 200. Thus, the sliding position 200 can also be normally pulled away from the rubber position. When the mold is closed, slide 200 resets, and panel 100 drives support block 1 to push against movable block 2 and reset. Support block 1 pushes against movable block 2 to ensure that movable pin 6 does not retract during injection molding.

[0039] The structure for vertical needle extraction of the slide in this embodiment helps to optimize the vertical needle extraction operation of the slide 200. The movable needle 6 does not need to be completely pulled out of the slide 200, so it will not press the slide 200 when the mold is closed, effectively improving the guarantee of production efficiency and product quality. The overall structure is simple and suitable for three-plate molds and pseudo three-plate molds.

[0040] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
