[0002] Injection molds are specialized tools used for the mass production of plastic products. They are usually made of high-hardness steel or aluminum. Molten plastic is injected into the mold cavity by an injection molding machine, and after cooling and solidification, it is formed into a part of a specific shape.

[0003] During the production of torpedo-shaped toys, injection molds are used. Traditional injection mold structures do not have the function of cushioning and protecting the product. Injection molds are mostly set horizontally. After the product is ejected, it will fall under the action of gravity. If the user does not receive the ejected product in time, the impact force generated by the fall can easily cause damage to the product and affect the production quality. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for torpedo-shaped toys, which solves the problem in the prior art that the ejected product will fall off naturally, and the impact force generated by the fall can easily damage the product.

[0005] This utility model provides the following technical solution: an injection mold for a torpedo-shaped toy, comprising:

[0006] Base;

[0007] The product protection mechanism is located on the top of the base and is used to cushion and protect the product that falls after being ejected.

[0008] The injection molding mechanism is located on the top of the base and is used to perform injection molding production of the product and automatically open the mold and eject the product.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model, through the overall design of the product protection mechanism, forms a frame structure along the product's drop path to receive the product. When the product falls, its bottom contacts the rubber base plate and the top of the raised block. At this time, the strip base plate slides on the support platform with the aid of a sliding shaft, compressing the elastic element. The elastic deformation generated by the elastic element buffers the impact force. Simultaneously, the rubber base plate and the raised block also undergo elastic deformation to buffer the impact force. Furthermore, when the side of the product contacts the frame structure, it squeezes the support arm, which undergoes elastic deformation to absorb the force. This fully ensures product safety and improves the product's production qualification rate. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: an injection mold for a torpedo-shaped toy, comprising:

[0026] Base 1;

[0027] Product protection mechanism 2 is located on the top of base 1 and is used to cushion and protect the product that falls after being ejected.

[0028] Injection molding mechanism 3 is located on top of base 1. Injection molding mechanism 3 is used to perform injection molding production of products and automatically open molds and eject them.

[0029] Product protection mechanism 2 includes a bottom buffer assembly and a side wing buffer assembly. The bottom buffer assembly includes a support platform 26. A sliding shaft 261 is slidably connected to the inner wall of the support platform 26. A strip base plate 263 is fixedly installed on the top of the sliding shaft 261. An elastic element 262 is fixedly installed on the bottom of the strip base plate 263. The bottom of the elastic element 262 is fixedly connected to the top of the support platform 26. A rubber base plate 264 is fixedly connected to the top of the strip base plate 263. A protrusion 265 is fixedly connected to the top of the rubber base plate 264.

[0030] The injection molding mechanism 3 includes an automatic mold opening assembly and a coordinated ejection assembly. The automatic mold opening assembly includes a fixed mold 33 and a moving mold 35. The top of the fixed mold 33 is fixedly connected to an injection port. The product protection mechanism 2 can form a frame structure along the path of the product's fall to receive the product. When the product falls, the bottom of the product will contact the top of the rubber base plate 264 and the protrusion 265. Under the impact force, the strip base plate 263 will slide on the support platform 26 with the help of the sliding shaft 261, and at the same time compress the elastic element 262. The elastic deformation generated by the elastic element 262 buffers the impact force. The rubber base plate 264 and the protrusion 265 are both made of rubber. At the same time, the rubber base plate 264 and the protrusion 265 will also generate elastic deformation to buffer the impact force and ensure the safety of the product.

[0031] As one implementation method in this embodiment, such as Figure 2 As shown, the side wing buffer assembly includes a column 21, which is fixedly installed on the top of the base 1. A connecting block 22 is fixedly installed on the column 21, and a horizontal support column 23 is fixedly installed on the outer wall of the connecting block 22. A rubber sleeve 24 is fixedly fitted on the outer wall of the horizontal support column 23. Through the design of the column 21, the connecting block 22 and the horizontal support column 23, a frame-shaped side enclosure can be formed. When the side of the product contacts the side enclosure, it will squeeze the support arm 25. The support arm 25 will generate elastic deformation to absorb the force and ensure the safety of the product.

[0032] As one implementation method in this embodiment, such as Figure 2 As shown, a support arm 25 is fixedly sleeved on the outer wall of the column 21, and a support platform 26 is fixedly installed on the side of the support arm 25. The support arm 25 is used to support the support platform 26 as a whole with the help of the column 21, so that the support platform 26 as a whole forms a frame-shaped bottom support unit, which is convenient for buffering vertical impact forces.

[0033] As one implementation method in this embodiment, such as Figure 1 As shown, a crossbeam 34 is fixedly installed on the left side of the fixed mold 33, and a support 31 is fixedly installed on the left side of the crossbeam 34. The support 31 is fixedly installed on the top of the base 1. A support 32 is fixedly installed on the bottom of the fixed mold 33. The support 32 is fixedly installed on the top of the base 1. The moving mold 35 can slide left and right on the outer wall of the crossbeam 34. When the moving mold 35 slides to the rightmost side, it will fit with the fixed mold 33 to realize the mold closing function. When the moving mold 35 slides to the left, it realizes the mold opening function. After the mold is closed, injection can be performed from the injection port on the fixed mold 33, which facilitates the injection molding production.

[0034] As one implementation method in this embodiment, such as Figure 1As shown, a cylinder 36 is fixedly installed on the left side of the support 31. The moving mold 35 is slidably connected to the outer wall of the crossbeam 34. The telescopic end of the cylinder 36 is fixedly connected to the left side of the moving mold 35. Controlling the cylinder 36 to extend can drive the moving mold 35 to slide to the right on the outer wall of the crossbeam 34. Controlling the cylinder 36 to retract can drive the moving mold 35 to slide to the left on the outer wall of the crossbeam 34, thus realizing the automatic opening and closing function and improving the automation level of this structure.

[0035] As one implementation method in this embodiment, such as Figure 4 As shown, the collaborative ejection assembly includes a fixed base 37 and a movable block 374. The fixed base 37 is fixedly installed on the outer wall of the fixed mold 33, and the movable block 374 is fixedly installed on the outer wall of the moving mold 35. An L-shaped sliding arm 371 is slidably connected to the inner wall of the fixed base 37. A connecting sleeve 372 is fixedly sleeved on the outer wall of the L-shaped sliding arm 371. A spring 373 is fixedly installed on the connecting sleeve 372. The end of the spring 373 away from the connecting sleeve 372 is fixedly connected to the left side of the fixed base 37, and the right side of the connecting sleeve 372 is movably connected to the left side of the fixed base 37. A connecting plate 375 located on the right side of the fixed mold 33 is fixedly installed on the back of the L-shaped sliding arm 371. An ejector pin 376 is fixedly connected to the left side of the connecting plate 375. The ejector pin 376 is slidably connected to... In the initial state, the connecting sleeve 372 can be pulled by the elastic force of the spring 373 on the fixed mold 33, so that the right side of the connecting sleeve 372 fits against the left side of the fixed seat 37. When the moving mold 35 moves to the left to open the mold, the end of the movement will pull the left end of the L-shaped sliding arm 371 through the movable block 374, so that the L-shaped sliding arm 371 slides in the inner cavity of the fixed seat 37. Then, through the transmission of the connecting plate 375, the ejector pin 376 can be driven to move to the left, so that the product in the inner cavity of the fixed mold 33 can be automatically ejected. When the moving mold 35 moves to the right to reset, the connecting sleeve 372 and the L-shaped sliding arm 371 can be reset by the elastic force of the spring 373, so that the ejector pin 376 can be reset, which facilitates the next injection molding operation.

[0036] Working principle: During use, the control cylinder 36 extends, causing the moving mold 35 to slide to the right on the outer wall of the crossbeam 34. The moving mold 35 slides to the far right and engages with the fixed mold 33, realizing the mold closing function. Then, injection is performed from the injection port on the fixed mold 33. After the toy shell cools and solidifies, the control cylinder 36 retracts, causing the moving mold 35 to slide to the left on the outer wall of the crossbeam 34, opening the mold. The end of the moving mold 35 will pull the left end of the L-shaped sliding arm 371 through the movable block 374, causing the L-shaped sliding arm 371 to slide in the inner cavity of the fixed seat 37. Then, through the transmission of the connecting plate 375, the ejector pin 376 can be driven to move to the left, thereby automatically ejecting the product from the inner cavity of the fixed mold 33. At this time, the product protection mechanism 2 forms a frame structure to buffer and receive the toy shell.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
