Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and more specifically, relates to an injection mold for the shell of a robot dog. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.

[0003] In injection mold design, the parts of the product that interfere with the mold opening direction are called undercuts. If an undercut occurs in the product, it cannot be designed using ordinary demolding methods. Therefore, there are corresponding undercut handling systems for this type of mold design.

[0004] However, in the current technology, the commonly used undercut processing method is to use a fixed mold push plate to follow the movement, which can be achieved by a snap-fit ​​machine or a spring; or by using an angled ejector rod to support the undercut core block, and then pulling the undercut core block out of the undercut structure of the product by angled ejection, which is called angled ejector core pulling. Since the angled ejection of the angled ejector core pulling device requires a large amount of internal space of the mold, the size of the mold increases. Moreover, these methods will cause undercut damage to the product to varying degrees during the movement process, resulting in low product qualification rate, high cost, and low efficiency.

[0033] An injection mold for a robot dog shell includes, from top to bottom, a top plate 10, a movable mold plate 20, a male mold core 30, a female mold core 40, a fixed mold plate 50, a square iron 60, and a bottom plate 70. The bottom end of the top plate 10 is connected to the movable mold plate 20, the bottom of the movable mold plate 20 is connected to the male mold core 30, and the top of the fixed mold plate 50 is connected to the female mold core 40. The male mold core 30 and the female mold core 40 are positioned correspondingly, and after mold closing, the male mold core 30 and the female mold core 40 close together. The mold cavity is formed by combining the top and bottom sides of the base plate 70, which is connected to the square iron 60. The top of the square iron 60 is connected to the fixed mold plate 50. The male mold core 30 is provided with a demolding mechanism 80 around its perimeter. The demolding mechanism 80 includes a slider 801, a slide rail 802, an inclined guide post 803, and a wedge block 804. The slide rail 802 is connected to the top of the fixed mold plate 50. The slider 801 is slidably connected to the slide rail 802. The wedge block 804 is fixedly connected to the bottom end of the moving mold plate 20. A recessed hole 90 is provided at the top of the fixed template 50 near the slide rail 802. The bottom end of the inclined guide post 803 passes through the slider 801 and abuts against the recessed hole 90. The upper part of the inclined guide post 803 is movably connected to the wedge block 804, and the lower part of the inclined guide post 803 is movably connected to the slider 801. The angle between the inclined guide post 803 and the horizontal plane is 15°-20°. When the injection molding is completed and the moving template 20 opens, it drives the wedge block 804 to move upward, thereby... When the inclined guide post 803 moves upward, it moves the slider 801, causing the slider 801 to slide outward on the slide rail 802, thus completing the core pulling. When the mold is closed, the moving mold plate 20 drives the wedge block 804 to move downward, which in turn drives the inclined guide post 803 to move downward. At this time, the inclined guide post 803 moves the slider 801, causing the slider 801 to slide inward on the slide rail 802 and abut against the periphery of the male mold core 30.

[0034] The wedge block 804 is provided with an oblique through hole 100, and a platform 110 is connected inside the oblique through hole 100. A locking platform 120 is connected to the upper part of the oblique guide post 803. When the wedge block 804 is sleeved with the oblique guide post 803, the bottom end of the locking platform 120 abuts against the top end of the platform 110 to prevent the oblique guide post 803 from disengaging from the wedge block 804.

[0035] The slider 801 is provided with pressure blocks 130 at both ends. The pressure blocks 130 are fixedly connected to the fixed template 50 and slidably connected to the slider 801. The pressure blocks 130 are used to ensure that the slider 801 moves on the slide rail 802 and prevent deviation.

[0036] A spring 140 is provided on the side of the slider 801 near the female mold core 40. One end of the spring 140 is connected to the female mold core 40, and the other end abuts against the slider 801. The spring 140 is used to assist the slider 801 to slide outward and open.

[0037] The slider 801 is provided with a plurality of limiting bolts 150 on the side away from the female mold core 40. The limiting bolts 150 are connected to the fixed template 50. The slider 801 is provided with a limiting groove 160 that matches the position of the limiting bolts 150. When the slider 801 moves to a set position, the limiting bolts 150 abut against the limiting groove 160 to limit the movement of the slider 801 and prevent the slider 801 from disengaging from the slide rail 802.

[0038] The contact surface between the slider 801 and the moving template 20 is an inclined surface 170, which serves as a guide for the moving template 20 when the mold is closed.

[0039] Multiple first wear-resistant plates 180 are connected to the inclined surface 170 to reduce the friction between the slider 801 and the moving template 20 and extend the service life.

[0040] A second wear-resistant plate 190 is provided between the fixed template 50 and the slider 801. The second wear-resistant plate 190 is connected to the fixed template 50 and is used to reduce the friction between the fixed template 50 and the slider 801, thereby extending the service life.

The upper part of the first guide post 230 is provided with a first guide sleeve 240 that is slidably connected to it. The first guide sleeve 240 is fixedly sleeved with the moving template 20. The first guide sleeve 240 and the first guide post 230 are used to maintain smooth movement and precise alignment when the moving template 20 is opening or closing the mold, and also serve as guides.

[0043] The top of the base plate 70 is provided with an ejector pin 250, an ejector pin panel 260, and an ejector pin base plate 270. The ejector pin 250, the ejector pin panel 260, and the ejector pin base plate 270 are all placed within the space enclosed by the square iron 60, the base plate 70, and the fixed template 50. The ejector pin base plate 270 is movably connected to the base plate 70. The top of the ejector pin base plate 270 is connected to the ejector pin panel 260. The bottom end of the ejector pin 250 is connected to the ejector pin panel 260. The top of the ejector pin 250 passes through the fixed template 50 and the female mold core 40 in sequence to eject the injection-molded shell product. After injection molding is completed, the ejector pin panel 260 and the ejector pin base plate 270 move upward, thereby driving the ejector pin 250 to move upward and eject the injection-molded shell product.

[0044] Return needles 280 are connected to the four corners of the ejector panel 260. The bottom end of the return needle 280 is connected to the ejector base plate 270, and the top end of the return needle 280 penetrates the fixed template 50. During the process of the ejector panel 260 driving the ejector 250 to push out and retract, the return needle 280 provides guidance to ensure smooth movement.

[0045] The ejector panel 260 is provided with a second guide post 290 and a second guide sleeve 300 near the return needle 280. The top end of the second guide post 290 is connected to the fixed template 50, and the bottom end is connected to the base plate 70. The upper part of the second guide sleeve 300 is sleeved with the ejector panel 260, and the lower part of the second guide sleeve 300 is sleeved with the ejector base plate 270. The second guide sleeve 300 is movably sleeved with the second guide post 290. The second guide post 290 and the second guide sleeve 300 play a role in precise guidance, positioning and protection, so that the ejector panel 260 keeps moving smoothly.
