The demoulding push rod is driven by the driving device 32, thereby driving the sliding plate to move, so that the embedded demoulding pin moves downward relative to the product.

[0012] The molding die set is further divided into an upper molding die and a lower molding die. The upper molding die is connected to the movable die set, and the lower molding die is connected to the fixed die set. The demoulding mechanism is placed on the lower molding die, and the demoulding push rod passes through the lower molding die and is connected to the driving device.

[0013] The inclined block surface of the embedded demoulding pin is designed with protrusions, one of which extends in a C shape and fits tightly with the inside of the product to form an inner buckle connection method, which is used for the connection structure between the supporting part and the installation part of the molded product.

[0014] The movable mold assembly also includes a top plate, on which an injection port is arranged, and the injection port is connected with the mold cavity, the molding mold assembly, the accommodating cavity, and the movable mold assembly.

[0015] The sliding plate is an inclined sliding plate.

[0020] The forming module is made of aluminum alloy.

[0021] After adopting the above technical solution, the beneficial effects of the utility model are:

[0022] Through the linkage of the embedded demoulding pin and the sliding inclined plate, the product can be removed, which simplifies the mold structure, reduces the difficulty of equipment processing, and facilitates the operator to open the mold of the equipment, effectively solving the problem that the existing mold needs to make multiple positions or move the position pin to completely remove the product. During operation, the movable mold group moves upward to open the mold, and the molding upper mold 311 and the molding lower mold 312 are also separated by the opening and closing of the mold. Subsequently, the sliding plate 3131 driving device 32 drives to move backward. Due to the existence of the limit block 3132, the backward movement of the embedded demoulding pin 3134 is blocked, and then moves down along the sliding plate 3131, which is equivalent to the embedded demoulding pin 3134 moving vertically downward relative to the product, so that the embedded demoulding pin 3134 is separated from the product. When the embedded demoulding pin 3134 moves to the bottom along the sliding plate 3131, it moves backward with the sliding plate 3131. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Reference Figure 1-5 , a multi-button demoulding mold is proposed,

[0038] It includes a fixed die set 2, a movable die set 1 arranged on the fixed die set 2, and an accommodating cavity 3 located between the movable die set 1 and the fixed die set 2, wherein the enclosed space between the movable die set 1 and the fixed die set 2 forms the accommodating cavity 3, a molding die set 31 is arranged in the accommodating cavity 3, a molding die set 31 is arranged in the molding die set 31, and the molding die set 31 is connected with the molding die set 31, the accommodating cavity 3, and the movable die set 1;

[0039] A driving device 32, the driving device 32 is located in the accommodating cavity 3 and connected to the molding module 31;

[0040] The mold cavity 313 is further provided with a demoulding mechanism 314, and the demoulding mechanism 314 further includes:

[0041] A sliding plate 3131, on which a limiting block 3132 is fixed;

[0042] An embedded demoulding pin 3134, wherein the embedded demoulding pin 3134 is connected to the sliding plate 3131 and can move downward relative to the sliding plate 3131;

[0043] The demoulding push rod 3133 is located on the sliding plate 3131 and passes through the molding module 31 to be connected with the driving device 32. The demoulding push rod 3133 is also connected with the sliding plate 3131. The driving device 32 drives the demoulding push rod 3133, thereby driving the sliding plate 3131 to move, so that the embedded demoulding pin 3134 moves downward relative to the product.

[0044] The molding module 31 is further divided into a molding upper mold 311 and a molding lower mold. The molding upper mold 311 is connected to the movable mold group 1, and the molding lower mold 312 is connected to the fixed mold group 2. The demolding mechanism 314 is placed on the molding lower mold 312, and the demolding push rod 3133 passes through the molding lower mold 312 and is connected to the driving device 32.

[0045] Since the product is a rearview mirror support, there is a concave surface at its edge, which makes the embedded demoulding pin 3134 unable to be demoulded through the forward and backward stroke. Therefore, the embedded demoulding pin 3134 is first moved downward and then moved backward to demould. The specific implementation structure relies on the cooperation between the limit block 3132 on the sliding plate 3131 and the embedded demoulding pin 3134.

[0046] When working, the driving device 32 of the sliding plate 3131 drives to move backwards. Due to the existence of the limit block 3132, the backward movement of the embedded demoulding pin 3134 is blocked, and then it moves down along the sliding plate 3131, which is equivalent to the embedded demoulding pin 3134 moving vertically downward relative to the product, so that the embedded demoulding pin 3134 is separated from the product. When the embedded demoulding pin 3134 moves to the bottom along the sliding plate 3131, it moves backwards with the sliding plate 3131. The utility model is simple and effective, and can solve the demoulding problem of products with inner concave surfaces at the edge position, and realize efficient mold demoulding operation.

[0047] It should also be noted that the main advantage of the sliding demoulding pin is to improve demoulding efficiency and protect the mold and molded objects. It releases the molded objects from the mold quickly and smoothly by sliding, reducing demoulding time and improving production efficiency, which is a necessary factor.

[0048] Furthermore, the surface of the inclined block of the embedded demoulding pin 3134 is designed with protrusions, one of which extends in a C shape and fits tightly with the inside of the product, forming an inner buckle connection method, which is used to form a connection structure between the supporting part and the mounting part of the product. This design can achieve reliable connection of the product and improve the stability and service life of the product. At the same time, this embedded design avoids the exposed threads or buckles and other connectors from causing damage to the product or affecting the appearance, conforms to ergonomics, and improves the quality and user experience of the product.

[0049] Furthermore, the movable mold assembly 1 further includes a top plate 12 , and an injection port 11 is disposed on the top plate 12 . The injection port 11 is connected to the mold cavity 313 , the molding mold assembly 31 , the accommodating cavity 3 , and the movable mold assembly 1 .

[0050] The sliding plate 3131 is a sliding inclined plate.

[0051] The fixed die set 2 further includes a bottom plate 21 , the bottom plate 21 has an area larger than the fixed die set 2 and extends in all directions.

[0052] In the present invention, the demoulding mechanism can quickly and smoothly release the molded product from the mold through the sliding movement of the sliding plate 3131, which can reduce the risk of damage to the mold and the molded product. At the same time, the inclination angle and sliding path of the inclined plate are reasonably designed to avoid collision or scratches with the mold or the product, protect the service life of the embedded demoulding pin 3134, and improve the quality of the product. Compared with other demoulding mechanisms, the sliding plate 3131 has a relatively simple structure and is relatively easy to operate. It only needs to control the movement trajectory and speed of the sliding plate 3131 to achieve the demoulding operation, which reduces the complexity and error probability of the operator. The sliding plate 3131 realizes demoulding through a mechanical device, which reduces the need for direct contact with the mold and reduces the risk of accidental injury. This design improves the safety of the operator and avoids the potential dangers caused by direct contact with the mold.

[0053] In addition, the top plate 12 and the bottom plate 21 are the supporting parts of the mold, which can allow the mold to maintain a stable shape and avoid deformation or shaking during the injection molding process, thereby ensuring the molding quality of the product. At the same time, the top plate 12 and the bottom plate 21 can also more conveniently disassemble and replace the mold core, thereby realizing the conversion of producing different types of products. This design can improve production efficiency and reduce production costs.

[0054] Furthermore, the number of the molding modules 31 is two or more, and the movable mold 1 is also provided with a diversion port 111, so that the molten plastic can be diverted to two or more molding modules 31. When two or more molding modules 31 are provided in the injection mold, multiple injection molding can be performed simultaneously, thereby improving production efficiency and shortening product processing cycle. In addition, the use of multiple molding modules 31 can reduce the number and frequency of use of each molding module 31, reduce the operating load of the mold, and thus extend the service life of the mold.

[0055] Furthermore, the fixed die set 2 and the movable die set 1 are also provided with cooling modules, which are divided into a first cooling module 41 and a second cooling module 42. The first cooling module 41 crosses the movable die set 1 and the molding upper die 311, and the second cooling module 42 crosses the fixed die set 2 and the molding lower die 312. During the injection molding process, a large amount of heat will be generated inside the mold. If the heat cannot be dissipated in time, the mold temperature will be too high, thereby affecting the product quality and mold life. Therefore, the main working principle of the cooling module is to inject coolant into the mold to reduce the mold temperature so as to achieve the purpose of controlling the temperature during the injection molding process.

[0056] When working, the cooling module injects coolant into the mold through the pipeline. The cooling module will continuously circulate the coolant so that the coolant can fully absorb the heat generated inside the mold. When the injection cycle ends, the cooling module will stop working, and the pressure in the mold will be automatically released. After the product is completely cooled, the product can be taken out. The cooling module can effectively reduce the cooling time of the product, speed up the molding cycle, thereby improving production efficiency, preventing deformation and defects caused by thermal stress and uneven shrinkage, and improving the dimensional stability, surface quality and mechanical properties of the product.

[0057] The forming module 31 is made of aluminum alloy, which has low density, good thermal conductivity, strong wear resistance and reduced energy consumption. These characteristics help to improve production efficiency, extend the service life of the mold, and reduce energy consumption.

[0058] The working principle of the utility model is roughly as follows:

[0059] During operation, the movable mold group moves upward to open the mold, and the molding upper mold 311 and the molding lower mold 312 are also separated by the opening and closing of the mold. Subsequently, the sliding plate 3131 driving device 32 drives to move backward. Due to the existence of the limit block 3132, the backward movement of the embedded demoulding pin 3134 is blocked, and then moves downward along the sliding plate 3131, which is equivalent to the embedded demoulding pin 3134 moving vertically downward relative to the product, so that the embedded demoulding pin 3134 is separated from the product. When the embedded demoulding pin 3134 moves to the bottom along the sliding plate 3131, it moves backward with the sliding plate 3131. The utility model is simple and effective, and can solve the demoulding problem of products with inner concave surfaces at the edge position, and realize efficient mold demoulding operation.

[0060] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
