Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a swinging inclined roof structure and an injection mold using the same. Background Art

[0002] Molds are the various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Simply put, a mold is a tool used to create a molded object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves surface processing by changing the physical state of the molded material, and is often called the "mother of industry." Injection molds are tools used to produce plastic products. Generally, they consist of an upper mold and a lower mold. During injection molding, the upper and lower molds close together to form the runner system and the mold cavity for the plastic product. During injection molding, the mold is clamped to the injection molding machine. Molten plastic is injected into the mold cavity and cooled and formed within the mold cavity. Simultaneously, the molten plastic cools in the runner system, forming a solid. After the plastic product is formed, the upper and lower molds separate, and the plastic product is ejected from the mold cavity by the ejection system. Finally, the upper and lower molds close again for the next injection. The entire injection molding process is a cyclical process.

[0003] In previous mold designs, straight ejectors or conventional inclined ejector structures were often used for products with simple demolding features. Straight ejectors only enable simple vertical ejection and are ineffective for products with lateral undercuts or complex curved surfaces. While conventional inclined ejectors can somewhat address the demolding challenges of products with single-direction undercuts, their limitations become apparent when products have complex structures and variable undercut directions. The relatively fixed motion path of conventional inclined ejectors makes it difficult to adapt to complex spatial demolding paths, potentially leading to product damage, deformation, or even failure to demold, severely impacting product quality and production efficiency.

[0004] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0006] A swinging inclined roof structure comprises an inclined roof seat, a movable seat and an inclined roof rod which are sequentially connected from bottom to top;

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-4 In the embodiment of the present invention, a swing inclined roof structure includes an inclined roof seat 1, a movable seat 2 and an inclined roof rod 3 which are sequentially connected from bottom to top;

[0029] The upper end of the inclined top seat 1 is provided with a first slide groove 4 with an inverted "T"-shaped cross-section, and the lower end of the movable seat 2 is extended to be provided with a T-shaped structure 5 matching the first slide groove 4. The T-shaped structure 5 can be slidably engaged in the first slide groove 4 from left to right, so that the movable seat 2 can slide along the inclined top seat 1, wherein the T-shaped structure 5 and the first slide groove 4 are inclined at the same inclination angle, and the matching surface of the movable seat 2 and the inclined top seat 1 is an inclined surface, and its inclination angle is the same as the inclination angle of the T-shaped structure 5 and the first slide groove 4;

[0030] The upper end of the movable seat 2 is provided with a second sliding groove 6 with a circular cross-section, and the lower end of the inclined ejector rod 3 is extended with a spherical structure 7 that matches the second sliding groove 6. The spherical structure 7 can be slidably engaged into the second sliding groove 6 from front to back, so that the inclined ejector rod 3 can slide and swing along the movable seat 2, wherein the upper end of the inclined ejector rod 3 is provided with a product profiling structure 8.

[0031] In the technical solution of the present utility model, the inclined ejector seat 1 serves as the stable foundation of the entire structure. The first chute 4, designed with an inverted "T"-shaped cross-section at its upper end, cooperates with the T-shaped structure 5 at the lower end of the movable seat 2. By setting the two at the same inclination angle, the guiding characteristics of the inclined surface are cleverly utilized to convert the linear driving force in the vertical direction during mold opening and closing into the oblique and smooth sliding of the movable seat 2 relative to the inclined ejector seat 1. For example, when injection molding a plastic pipe fitting with an internal spiral undercut structure, this oblique fit enables the movable seat 2 to gradually move along an oblique trajectory that matches the undercut spiral line of the pipe fitting during the ejection process, laying a solid foundation for the subsequent precise movement of the inclined ejector rod 3.

[0032] The second circular slot 6 at the upper end of the movable seat 2 and the spherical structure 7 at the lower end of the inclined ejector rod 3 form a flexible and changeable connection method. The spherical structure 7 has a unique degree of freedom of movement in the second circular slot 6. It can slide linearly in the front and rear directions and can swing freely within a certain range around the center of the ball. When the mold opening and ejection operation is started, as the movable seat 2 slides obliquely on the inclined ejector seat 1 according to a predetermined inclination angle, the inclined ejector rod 3, due to the exquisite connection between the spherical structure 7 and the second circular slot 6, will not only be lifted upward with the movable seat 2 as a whole, but also can be flexibly adjusted to the swing angle according to the specific shape and position differences of complex structures such as asymmetric undercuts and multi-angle side recesses inside the product with the center of the spherical structure 7 as the fulcrum. Taking the injection molding of an electronic product shell with an irregular polygonal shape and multiple concave and undercuts as an example, the product profiling structure 8 customized according to the complex internal structure of the product at the upper end of the inclined ejector rod 3 can fit tightly with the interior of the product during the entire demoulding process, and evenly and accurately apply the demoulding force to ensure that the product is smoothly removed from the mold cavity;

[0033] In summary, the swinging inclined top structure can effectively meet the demoulding needs of products with multi-directional undercuts and complex side concave structures. Compared with traditional straight top and ordinary inclined top structures, its unique sliding and swinging composite motion mode can better fit the complex spatial shape of the product, avoid the difficulty or damage of product demoulding due to a single demoulding direction, and greatly improve the success rate of the mold for demoulding complex products; in the demoulding process, since the swinging inclined top structure can adapt to the product shape more accurately, it reduces excessive pulling and squeezing of the product, thereby significantly reducing the probability of defects such as strain and deformation during product demoulding, effectively ensuring the appearance quality and dimensional accuracy of the product, and improving the overall quality of the product. At the same time, it can effectively reduce production interruptions and waste caused by demoulding problems, making the injection molding production process smoother and more efficient, without the need to frequently adjust the mold or repair the product, shortening the production cycle of a single product, thereby improving the production efficiency of the entire production line and reducing production costs.

[0034] In an embodiment of the utility model, two oppositely arranged first clamping blocks 9 are provided on the inner side of the upper end of the inclined top seat 1, and the first slide groove 4 is formed between the two first clamping blocks 9, and the end faces of the two first clamping blocks 9 are both inclined surfaces; the first slide groove 4 includes a horizontal groove 10 and a vertical groove 11, and the first clamping block 9 is located between the wall connection of the horizontal groove 10 and the vertical groove 11 and is arranged in an arc-shaped transition.

[0035] The two first clamping blocks 9 arranged opposite to each other on the inner side of the upper end of the inclined top seat 1 form a unique first slide groove 4 structure. The end faces of the two first clamping blocks 9 are both inclined surfaces, which echo the inclined cooperation of the T-shaped structure 5 to ensure that the movable seat 2 slides stably along the predetermined inclined angle on the inclined top seat 1. The first slide groove 4 includes a horizontal groove 10 and a vertical groove 11, and the first clamping block 9 is located between the wall connection of the horizontal groove 10 and the vertical groove 11 to form an arc-shaped transition. The design of this arc-shaped transition is the key point. When the T of the movable seat 2 When the T-shaped structure slides in the first slide groove 4, especially when the movement direction changes or is subjected to an uneven effect of the demoulding force, the arc transition can guide the T-shaped structure 5 to smoothly transition between the horizontal groove 10 and the vertical groove 11, avoiding jamming or stress concentration caused by right angles or sharp edges; for example, when injecting a plastic product with a complex curve undercut and a demoulding force with large changes in direction at different stages, the sliding path of the T-shaped structure 5 in the first slide groove 4 will be continuously adjusted with the demoulding process, and the arc-shaped transition wall can adapt to this change well, ensuring the continuity and smoothness of the movement of the movable seat 2, and thus providing a reliable foundation for the precise movement of the inclined ejector rod 3.

[0036] In an embodiment of the present invention, two oppositely arranged second clamping blocks 12 are provided on the inner side of the upper end of the movable seat 2, a second slide groove 6 is formed between the two second clamping blocks 12, and an inclined expansion opening 13 connected to the second slide groove 6 is formed between the end surfaces of the two second clamping blocks 12.

[0037] The second chute 6 formed by the two oppositely arranged second clamping blocks 12 on the inner side of the upper end of the movable seat 2 and the connected inclined flared opening 13 are designed based on the careful consideration of the movement characteristics of the inclined ejector rod 3. The circular second chute 6 formed between the two second clamping blocks 12 provides a basic sliding and swinging space for the spherical structure 7 at the lower end of the inclined ejector rod 3, so that it can flexibly move within a certain range to adapt to the demoulding requirements of the product, and the design of the inclined flared opening 13 further expands the freedom of movement and adaptability of the inclined ejector rod 3. During the demoulding process, when the inclined ejector rod 3 needs to swing more significantly or due to the special structure of the product, As a result, the inclined flare 13 can play a guiding and buffering role when the spherical structure 7 enters and exits certain positions of the second slide groove 6; for example, when injection molding plastic products with deep concave and tricky undercut angles, the spherical structure 7 needs to smoothly connect and disengage with the second slide groove 6 at different spatial positions during the initial contact of the inclined ejector 3 with the undercut part of the product and the reset process after demolding. The inclined flare 13 can make the spherical structure 7 enter and exit the second slide groove 6 more smoothly, avoiding collisions and jams caused by sudden contact or disengagement, and ensuring the continuity and accuracy of the movement of the inclined ejector 3.

[0038] In one implementation of the embodiment of the present invention, a cooling channel is axially provided inside the lift rod 3 , and an inlet and an outlet of the cooling channel are located at the lower end and the upper end of the lift rod 3 , respectively.

[0039] During the injection molding process, the plastic melt has a relatively high temperature. When the melt contacts the inclined ejector pin 3 for a long time, the temperature of the inclined ejector pin 3 will increase. A cooling channel is axially arranged inside the inclined ejector pin 3, and its inlet and outlet are respectively located at the lower end and one side of the upper end of the inclined ejector pin 3. By utilizing the principle of heat conduction, the heat of the inclined ejector pin 3 is taken away by the circulation of the cooling medium in the channel. For example, when injection molding high-temperature molten engineering plastic products (such as polycarbonate), after the plastic melt is injected into the mold cavity, it will quickly transfer the heat to the inclined ejector pin 3 in contact with it. The cooling water or cooling oil in the cooling channel flows in from the lower end inlet, absorbs the heat of the inclined ejector pin 3 in the process of flowing through the entire channel, and then flows out from the outlet on one side of the upper end, thereby keeping the inclined ejector pin 3 at a relatively low temperature, avoiding deformation or affecting its mechanical properties due to excessive temperature, and ensuring the dimensional accuracy and movement stability of the inclined ejector pin 3 during the demolding process.

[0040] A fixed interface is provided on the stationary part of the mold (such as the bottom plate or fixed plate of the mold) for connecting an external cooling water pipe. The inlet at the lower end of the inclined ejector pin 3 is connected to the cooling water pipe fixed to the mold through a movable joint or a quick joint to ensure that the cooling medium can smoothly enter the cooling channel of the inclined ejector pin 3. The outlet on one side of the upper end of the inclined ejector pin 3 is also connected to the return pipe outside the mold or the return port of the cooling system through a pipe. This fixed external pipe connection method can ensure that the supply and return of the cooling medium remain stable during the movement of the inclined ejector pin 3. Although the inclined ejector pin 3 will slide and swing inside the mold, since the external pipe is fixed to the mold, when the inclined ejector pin 3 moves, the part connected to the external pipe will displace relative to the stationary part of the mold. In order to adapt to this displacement, the connection part usually adopts a movable joint or hose connection. For example, a pipe with a certain degree of flexibility such as a rubber hose or a metal bellows can be used so that when the inclined ejector pin 3 moves, the external pipe can bend and stretch with its movement while ensuring that the circulation of the cooling medium is not affected.

[0041] In one embodiment of the present invention, lubrication grooves 14 are provided on both side walls of the first slide groove 4 of the inclined ejector seat 1, and the lubrication grooves 14 are connected to the first slide groove 4 through fine holes 15, wherein the lubrication grooves 14 are filled with grease, and when the inclined ejector rod 3 and the movable seat 2 move, the grease can seep out and act on the mating surface of the T-shaped structure 5 and the first slide groove 4.

[0042] In the swinging inclined roof structure, there is a relative movement between the first slide groove 4 of the inclined roof seat 1 and the T-shaped structure 5 of the movable seat 2, and a large friction force will be generated when subjected to the demoulding force and the like. The setting of the lubrication groove 14 is intended to reduce this friction and ensure the smoothness of the movement. The lubrication groove 14 is located on the two side walls of the first slide groove 4 and is connected to the first slide groove 4 through the fine hole 15, forming an ingenious automatic lubrication system. When the mold is assembled, the lubrication groove 14 is filled with grease. When the inclined roof rod 3 and the movable seat 2 start to move, due to the sliding and squeezing of the T-shaped structure 5 in the first slide groove 4, as well as the slight vibration and gap change between the components, the grease in the lubrication groove 14 will be subjected to pressure. Under the action of pressure, the grease seeps out through the connected fine hole 15 to the mating surface of the T-shaped structure and the first slide groove 4, forming a uniform lubrication film, which is conducive to ensuring that there is always sufficient lubrication during the movement and avoiding dry friction and excessive wear.

[0043] See also Figure 5The present invention also proposes an injection mold, including the above-mentioned rocking inclined top structure, and also including an upper mold and a lower mold 16, the upper mold and the lower mold 16 are connected to each other to form a mold cavity 18 for molding a product, the upper mold is provided with a glue feeding mechanism connected to the mold cavity 18, and the lower mold 16 is provided with an ejection mechanism connected to the mold cavity 18, wherein the ejection mechanism includes an ejector plate 17 movably connected to the lower mold 16, and a rocking inclined top structure provided on the ejector plate 17.

[0044] The swinging inclined ejector structure is integrated into the overall mold system including the upper mold and the lower mold 16. The glue feeding mechanism of the upper mold is responsible for injecting the high-temperature molten plastic melt into the mold cavity 18 formed by the upper mold and the lower mold 16, so that the plastic is molded according to the shape of the product in the mold cavity 18. When the molding process is completed, the ejection mechanism of the lower mold 16 starts to operate. The ejector plate 17, as a key part of the ejection mechanism, carries the swinging inclined ejector structure and enables it to play a role at the right time. When the mold is opened, the ejector plate 17 moves upward under the push of the power source (such as the ejector device of the injection molding machine). The inclined ejector structure is located on the ejector plate 17, and its inclined ejector seat 1, movable seat 2 and inclined ejector rod 3 will move upward together with the ejector plate 17. During this process, the movement mode of the inclined ejector rod 3 is unique due to the unique design of the swinging inclined ejector structure. It can not only rise vertically with the ejector plate 17, but also swing through the cooperation of the lower end spherical structure 7 and the upper end circular second slide groove 6 of the movable seat 2. At the same time, the movable seat 2 can slide in the inverted "T"-shaped first slide groove 4 of the inclined ejector seat 1, thereby adapting to the complex undercut and undercut structures of the product in multiple directions and smoothly ejecting the product from the mold cavity 18.
