Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and in particular to a spring block mechanism and an injection mold. Background Technology

[0002] Injection molding is a common method for manufacturing plastic products. Injection molds typically include an upper mold and a lower mold. The lower mold has multiple spring blocks. When the upper mold and the lower mold are connected, the multiple spring blocks can be pushed closer to each other to form a molding groove. By injecting injection liquid into the molding groove, injection molded parts can be formed.

[0003] In existing technologies, products typically require multiple processing steps, each with a chance of producing defective products. Furthermore, to improve manufacturing efficiency, automated injection molding is often used. This involves using robotic arms or other components to directly move the product, processed in one manufacturing process, into a plastic mold. After being placed in a predetermined position, the mold automatically closes. However, when there are dimensional deviations in the product, such as if the product size is too large, the mold is more easily damaged by the product after mold closing, requiring mold repair or replacement. This increases maintenance costs and leads to longer downtime, affecting product manufacturing efficiency.

[0004] Therefore, there is an urgent need for a spring block mechanism, a spring block mechanism and an injection mold to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a spring block mechanism and injection mold that can accommodate fluctuations in product dimensions, reduce the probability of the mold being damaged by the product, reduce product manufacturing costs, and improve product manufacturing efficiency.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] The spring mechanism includes:

[0008] A slider assembly having a receiving groove;

[0009] The spring block assembly includes a push block that is slidably disposed in the receiving groove along a preset direction and a spring block connected to the push block, the spring block being used to abut against the product;

[0010] An elastic component is disposed within the receiving groove and abuts against the push block and the groove wall of the receiving groove in the preset direction.

[0011] Optionally, the slider assembly has a through hole communicating with the receiving groove, the spring block is slidably inserted in the through hole, and one end of the spring block is fixed to the push block, while the other end extends out of the through hole and abuts against the product.

[0012] Optionally, the spring block includes a rod fixed at one end to the push block, a limiting part fixed at the other end of the rod, and an abutment fixed to the limiting part. The rod slides through the through hole, the cross-sectional dimension of the limiting part is larger than the cross-sectional dimension of the through hole, and the abutment is used to abut against the product.

[0013] Optionally, it also includes a limiting component, the limiting component including a limiting pin and a limiting block fixed to one end of the limiting pin, the other end of the limiting pin being fixed to the spring block, the groove wall of the receiving groove being provided with a limiting groove communicating with the receiving groove, the limiting block being located in the limiting groove, and the through hole being provided in the groove wall of the limiting groove.

[0014] Optionally, the limiting component further includes a limiting pad installed in the limiting groove, and the limiting block is supported on the limiting pad.

[0015] Optionally, the slider assembly includes a slider and a protrusion protruding from the slider, the receiving groove is disposed in the slider, a portion of the through hole is disposed in the slider, and another portion is disposed in the protrusion.

[0016] Optionally, a support block is provided on the surface of the protrusion away from the slider, and the support block is used to press against the product.

[0017] Optionally, one of the push block and the slider assembly is provided with a guide block and the other is provided with a guide groove, and the guide block slides in the guide groove.

[0018] Optionally, the top surface of the slider assembly is provided with a socket, and one wall of the socket is an inclined wall.

[0019] An injection mold includes a lower mold and one or more spring block mechanism groups. Each spring block mechanism group includes multiple spring block mechanisms as described above. The multiple spring blocks in each spring block mechanism group are used to abut different positions of the product. The spring block mechanisms are slidably mounted on the lower mold.

[0020] The beneficial effects of the spring block mechanism and injection mold proposed in this invention are as follows: A movable push block is embedded in the slider assembly, and an elastic component is provided between the push block and the groove wall of the receiving groove. This allows the spring block to elastically abut against the product under the action of the push block and the elastic component. When the upper limit of the product's size in the preset direction is too large, the spring block will retreat under the pressure of the product and push the push block to squeeze the elastic component, thereby avoiding interference between the spring block and the product and causing damage. When the lower limit of the product's size in the preset direction is too small, the spring block moves closer to the product under the elastic force of the elastic component and abuts against the product, thereby avoiding product overflow defects, accommodating product size fluctuations, reducing the probability of the spring block mechanism being damaged by the product, reducing product manufacturing costs, and improving product manufacturing efficiency.

It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0045] This embodiment provides a spring block mechanism that can accommodate fluctuations in product dimensions, reducing the likelihood of mold damage to the product, lowering product manufacturing costs, and improving product manufacturing efficiency.

[0046] Before introducing the spring mechanism provided in this embodiment, this embodiment describes the structure of the product, such as... Figures 4 to 6 As shown, the product includes a first material block 100, a second material block 200 fixed to the top of the first material block 100, and a terminal 300 formed on the second material block 200. The first material block 100 is made of ceramic, and the second material block 200 is made of plastic. The second material block 200 is sleeved on one end of the first material block 100. The terminal 300 is bent, and a portion of the terminal 300 is attached to the side wall of the first material block 200. That is, a portion of the terminal 300 is located between the first material block 100 and the second material block 200, and the other portion is located on the top surface of the second material block 200.

[0047] Please see Figure 1 and Figure 2 The spring block mechanism 20 includes a slider assembly 1, a spring block assembly 2, an elastic component 3, and a limiting component 4.

[0048] The slider assembly 1 has a receiving groove 11, specifically, the receiving groove 11 is disposed on the top surface of the slider assembly 1. It should be noted that the slider assembly 1 in this embodiment can be a mold slider in an injection mold. The spring block assembly 2 includes a push block 21 slidably disposed in the receiving groove 11 along a preset direction and a spring block 22 connected to the push block 21. The spring block 22 is used to abut against the product. Specifically, one end of the spring block 22 is connected to the push block 21, and the other end is used to abut against the product. In this embodiment, the other end of the spring block 21 is used to press a portion of the terminal 300 against the side wall of the first material block 100, so that the terminal 300 can be fixed when the second material block 200 is formed.

[0049] like Figure 2As shown, the elastic component 3 is disposed within the receiving groove 11 and abuts against the push block 21 and the groove wall of the receiving groove 11 in a preset direction. The elastic component 3 allows the spring block 22 to elastically abut against the product, thereby accommodating the dimensional deviation of the first material block 100 and the terminal 300 in the preset direction. It should be noted that the elastic component 3 is in a compressed state to ensure that the spring block 22 can press against a portion of the terminal 300. When the dimensions of the first material block 100 and a portion of the terminal 300 in the preset direction are slightly larger, the elastic component 3 is compressed; when the dimensions of the first material block 100 and a portion of the terminal 300 in the preset direction are slightly smaller, under the action of the elastic force of the elastic component 3, the spring block 22 can also press the terminal 300 against the first material block 100. In this embodiment, the elastic component 3 can be a spring.

[0050] The spring block mechanism 20 provided in this embodiment has a movable push block 21 embedded in the slider assembly 1, and an elastic component 3 is provided between the push block 21 and the groove wall of the receiving groove 11. This allows the spring block 22 to elastically abut against the product under the action of the push block 21 and the elastic component 3. When the upper limit of the product's size in the preset direction is too large, the spring block 22 will retreat under the pressure of the product and push the push block 21 to squeeze the elastic component 3, thereby avoiding interference between the spring block 22 and the product and causing damage. When the lower limit of the product's size in the preset direction is too small, the spring block 22 moves closer to the product under the elastic force of the elastic component 3 and abuts against the product, thereby avoiding product glue overflow defects, accommodating product size fluctuations, reducing the probability of the spring block mechanism 20 being damaged by the product, reducing product manufacturing costs, and improving product manufacturing efficiency.

[0051] In this embodiment, the distance between the push block 21 and the rear wall of the receiving groove 11 is 0-0.1 mm, so that the movement range of the spring block 22 when it retracts is 0-0.1 mm. The distance between the push block 21 and the front wall of the receiving groove 11 is 0-0.1 mm, so that the movement range of the spring block 22 when it moves closer to the product is 0-0.1 mm. In this embodiment, the rear wall and the front wall are two opposite walls of the receiving groove 11 in a preset direction.

[0052] In addition, the spring block mechanism 20 provided in this embodiment, with the spring block assembly 2 set in the slider assembly 1, does not occupy additional space in the injection mold layout, requires less space, has a simple structure, and has high operational reliability.

[0053] Optionally, the slider assembly 1 has a through hole 12 located on the side wall of the receiving groove 11 and communicating with the receiving groove 11. The spring block 22 is slidably inserted into the through hole 12, with one end of the spring block 22 fixed to the push block 21 and the other end extending out of the through hole 12 and abutting a portion of the top end 300. By providing the through hole 12, the stability of the movement of the spring block 22 can be improved, and the direction of movement of the spring block 22 can be guaranteed to prevent the spring block 22 from tilting.

[0054] Further reading is available upon request. Figure 2 The spring block 22 includes a rod portion 221, a limiting portion 222, and a bottom portion 223 connected in sequence. Specifically, one end of the rod portion 221 is fixed to the push block 21, the limiting portion 222 is fixed to the other end of the rod portion 221, and the bottom portion 223 is fixed to the surface of the limiting portion 222 away from the rod portion 221. The rod portion 221 slides through the through hole 12, and the cross-sectional dimension of the limiting portion 222 is larger than the cross-sectional dimension of the through hole 12, so that the limiting portion 222 can be located outside the through hole 12, thereby limiting the movement limit of the spring block 22 in a preset direction, specifically limiting the backward movement limit of the spring block 22.

[0055] The aforementioned abutment 223 is used to abut the product. In this embodiment, the cross-sectional dimension of the limiting part 222 is larger than the cross-sectional dimension of the rod part 221 and the cross-sectional dimension of the abutment 223. In this embodiment, the cross-sectional dimension can be the diameter, length, width, area, etc. of the cross-section. For example, the fact that the cross-sectional dimension of the limiting part 222 is larger than the cross-sectional dimension of the through hole 12 can be understood as the cross-sectional length of the limiting part 222 being larger than the cross-sectional length of the through hole 12.

[0056] Optionally, the top abutment 223 has a flat top surface for supporting another portion of the terminal 300, and the top abutment 223 is filled with injection-molded material around its perimeter to form a first material block 100, and as... Figure 3 and Figure 5 As shown, the first material block 100 forms a material hole 1001 at the position corresponding to the top 223.

[0057] Optionally, please continue to see Figure 2 The spring block mechanism 20 also includes a limiting component 4, which limits the movement limit of the spring block 22 in a preset direction. Specifically, the limiting component 4 limits the movement limit of the spring block 22 when it moves closer to the product. Specifically, as... Figures 8 to 11 As shown, the limiting component 4 includes a limiting pin 41 and a limiting block 42 fixed to one end of the limiting pin 41. The other end of the limiting pin 41 is fixed to the rod portion 221 of the spring block 22. In some embodiments, the limiting pin 41 passes through a hole structure on the rod portion 221. The groove wall of the receiving groove 11 is provided with a limiting groove 13 communicating with the receiving groove 11, and the limiting block 42 is located in the limiting groove 13. When the rod portion 221 moves in a preset direction, the limiting pin 41 and the limiting block 42 move with the rod portion 221. When the limiting block 42 moves to contact the groove wall of the limiting groove 13, the limiting block 42 and the limiting pin 41 cannot continue to move, thus preventing the rod portion 221 from moving further, thereby limiting the movement limit of the rod portion 221. A through hole 12 is provided in the groove wall of the limiting groove 13 in the preset direction.

[0058] Furthermore, the limiting component 4 also includes a limiting pad 43 installed in the limiting groove 13, the limiting block 42 is supported on the limiting pad 43, and the limiting block 42 is movable relative to the limiting pad 43. In some embodiments, the limiting pad 43 is detachably installed at the bottom of the limiting groove 13, so that the setting of the limiting pad 43 can facilitate the disassembly and replacement of the limiting block 42 and the limiting pin 41.

[0059] Optionally, such as Figure 5 or Figure 6 As shown, the slider assembly 1 includes a slider 14 and a protrusion 15 protruding from the slider 14. In this embodiment, the protrusion 15 protrudes along a predetermined direction, a receiving groove 11 is provided in the slider 14, a portion of the through hole 12 is provided in the slider 14, and another portion is provided in the protrusion 15. The two sides of the protrusion 15 in the width direction have inclined surfaces, which cooperate with the inclined surface of the lower mold 10 of the injection mold to limit the movement limit of the slider assembly 1 on the lower mold 10.

[0060] like Figure 1 As shown, a support block 16 is provided on the surface of the protrusion 15 away from the slider 14. The support block 16 is used to press against the product. Specifically, the support block 16 is used to press against the first material block 100, and there is no gap between the support block 16 and the first material block 100 to prevent the colloid from overflowing. The second material block 200 is formed above the support block 16.

[0061] Optionally, such as Figure 2 As shown, of the push block 21 and the slider assembly 1, one is provided with a guide block 211 and the other with a guide groove 111. The guide block 211 slides in the guide groove 111 to guide the sliding of the push block 21, so that the push block 21 can slide stably. In this embodiment, the guide groove 111 is provided on the slider assembly 1, specifically in the groove wall of the receiving groove 11, and the guide block 211 is provided on the side wall of the push block 21, so that the guide groove 111 and the guide block 211 cooperate with each other to limit the push block 21 in the groove depth direction of the receiving groove 11.

[0062] Optionally, the top surface of the slider assembly 1 is provided with an insertion hole 17, one wall of which is an inclined wall 171. Specifically, the insertion hole 17 is provided on the top surface of the slider 14, and there are two insertion holes 17, which are respectively located on both sides of the receiving groove 11. The insertion hole 17 is used for the guide rod assembly 50 of the upper mold of the injection mold to be inserted. In some embodiments, the guide rod assembly 50 includes a block 501 and two guide rods 502 connected to the bottom surface of the block 501, and each of the two guide rods 502 is inserted into two insertion holes 17.

[0063] This embodiment also provides an injection mold, including a lower mold 10 and one or more spring block mechanism assemblies. When the injection mold includes one spring block mechanism assembly, the injection mold is a single-cavity injection mold; when the injection mold includes multiple spring block mechanism assemblies, the injection mold is a multi-cavity injection mold. Each spring block mechanism assembly includes multiple spring block mechanisms 20 as described above. Furthermore, the multiple spring blocks 22 of each spring block mechanism assembly are used to abut against different positions of the product. Specifically, the first material block 100 has multiple sides, and the multiple spring blocks 22 are used to abut against the multiple sides of the first material block 100 respectively. Additionally, the multiple spring blocks 22 are used to contact different terminals 300 to fix the multiple terminals 300 to different sides of the first material block 100. Figure 14 As shown, multiple spring block mechanisms are arranged in an array on the lower mold 10 to achieve mass production of the product.

[0064] Each spring block mechanism 20 is slidably mounted on the lower mold 10. Specifically, the slider 14 is slidably mounted on the lower mold 10. The top surface of the lower mold 10 has multiple pressure blocks 60, which limit the slider 14 in the thickness direction of the lower mold 10, so that the slider 14 can only slide in the length and width directions of the lower mold 10. A support column 30 is fixed on the lower mold 10, with one support column 30 corresponding to each spring block mechanism group. The support column 30 is used to support the product; specifically, the support column 30 is used to support the first material block 100. Please refer to [link / reference]. Figure 10 and Figure 11 Each slider 14 of a spring block mechanism assembly is provided with a spring structure 40 between it and the support column 30. That is, each spring block mechanism is provided with a spring structure 40 between it and the support column 30. The spring structure 40 enables the slider assembly 1 to elastically abut against the first material block 100. In addition, the spring structure 40 also has the function of resetting the spring block mechanism. Specifically, when the injection mold is in the mold closed state, the guide rod 502 is inserted into the insertion hole 17, the spring structure 40 is in a compressed state and stores elastic potential energy. At this time, the spring block mechanism assembly is in a converged state. When the mold is opened, the guide rod 502 is pulled out from the insertion hole 17. At this time, under the action of the spring structure 40, each spring block mechanism moves away from the product, so that each spring block mechanism separates from the product, and the spring block mechanism assembly is in an open state.

[0065] When manufacturing a product using the injection mold provided in this embodiment, the product is first supported on the support column 30. In some embodiments, the top surface of the support column 30 may be provided with a product groove, so that the bottom end of the product can be pre-positioned in the product groove. Then, the terminal 300 is placed at the abutment 223 of the spring block assembly 2, so that a part of the terminal 300 contacts the end face of the abutment 223 and the other part contacts the top surface of the abutment 223. Then, the guide rod assembly 50 is controlled to press down, so that each guide rod 502 can be inserted into the corresponding insertion hole 17. It should be noted that the guide rod assembly 50 can be fixed to the upper mold. During the mold closing process, the upper mold presses down to drive the guide rod assembly 50 to press down. As the guide rod 502 continues to move down, it can push multiple spring block mechanisms 20 in a spring block mechanism group to move closer to each other and towards the product through the inclined wall 171, until the support block 16 of each spring block mechanism 20 abuts against the groove wall of the first material block 100. At this time, the injection mold is in the shape of Figure 12 The state is shown. During this process, the slider assembly 1 moves the spring block assembly 2 closer to the product, and the spring block 22 presses the terminal 300 against the side wall of the first material block 100. When the size of the first material block 100 is too large, the elastic component 3 is compressed so that the spring block 22 elastically presses against the terminal 300. The terminal 223, the first material block 100, the support block 16 and the upper mold can form a casting cavity. By injecting colloid into the casting cavity, the second material block 200 can be formed.

[0066] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments.
