Description

Technical Field

[0002] Silicone rubber production molds are molds made from silicone rubber as raw material through specific processes, used for product replication and manufacturing.

[0003] As described in announcement number CN221184484U, a rapid prototyping precision mold includes a base. A set of support seats is fixedly installed on the lower left and lower right sides of the base, with the two sets of support seats symmetrically distributed and each set consisting of two seats. A set of support columns is fixedly installed on the upper left and upper right sides of the base. This rapid prototyping precision mold, through the installation of a rotating assembly and a base, a hydraulic cylinder and a baffle plate, allows the baffle plate to be removed from the moving slot by a handle. The hydraulic cylinder then drives a push rod and a push plate to move downwards, and the push plate, in turn, allows the molded product to be quickly removed from the mold frame. A fixed frame is also included; the rotation of the fan blades draws air into the fixed frame through the air inlet, and the airflow is then transported to the cooling tank through a connecting pipe, accelerating the cooling speed of the product.

[0004] This patented technology can achieve rapid cooling through a fan, but existing molds do not have an automatic ejection structure. During demolding, manual demolding is required, which not only increases operation time but also reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing molds do not have an automatic ejection structure, and manual demolding is required during demolding, which not only increases operation time but also reduces production efficiency.

[0007] Furthermore, the motor is electrically connected to an external power source via a control switch, and the output end of the motor is fixedly connected to the bidirectional screw.

[0008] Furthermore, the bidirectional screw is connected to the moving block via a threaded hole, and the slider of the extrusion block matches the groove of the lifting block.

[0009] Furthermore, the slider and the groove form a sliding connection, and the bidirectional screw and the bearing form a rotating connection.

[0011] Furthermore, a water pipe is connected to one side surface of the water pump, and a cooler is connected to the surface of the water pipe.

[0012] Furthermore, one end of the water pipe is connected to the cooling cavity of the mold body, and a cooling fan is connected to the operating table at a position matching the cooler.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when it is necessary to quickly demold the silicone rubber in the mold body, the motor can be turned on by controlling the switch, so that the two sets of moving blocks move inward at the same time and squeeze the lifting block, so that the lifting block can push the lifting plate upward, and the lifting plate pushes the silicone rubber in the mold body to achieve the effect of quick demolding, avoiding manual demolding and improving demolding efficiency.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1 - Figure 4 As shown, this utility model provides a silicone rubber rapid prototyping mold structure, including an operating table 1. An automatic ejection assembly 2 is provided on the surface of the operating table 1. The automatic ejection assembly 2 includes a mold body 201. A motor 202 is provided on one side of the interior of the operating table 1. A bidirectional screw 203 is connected to the output end of the motor 202. A bearing 204 is connected to one end of the bidirectional screw 203. Moving blocks 205 are connected to both sides of the bidirectional screw 203. Threaded holes are formed inside the moving blocks 205. An extrusion block 206 is connected to the top of the moving blocks 205. A slider 207 is connected to the surface of the extrusion block 206. Two sets of... A lifting block 208 is provided on the inner side of the extrusion block 206. Slide grooves 209 are provided on both sides of the lifting block 208. A lifting plate 210 is connected to the top of the lifting block 208. The motor 202 is electrically connected to an external power source through a control switch. The output end of the motor 202 is fixedly connected to the bidirectional screw 203. The bidirectional screw 203 is threadedly connected to the moving block 205 through a threaded hole. The slider 207 of the extrusion block 206 matches the slide groove 209 of the lifting block 208. The slider 207 and the slide groove 209 are slidably connected. The bidirectional screw 203 is rotatably connected to the bearing 204.

[0025] The effect achieved in Embodiment 1 is as follows: When it is necessary to demold the silicone rubber inside the mold body 201, the forward rotation function of the motor 202 can be turned on by controlling the switch, so that the output end of the motor 202 can drive the bidirectional screw 203 to rotate forward. At the same time as the bidirectional screw 203 rotates forward, it will also rotate with the two sets of moving blocks 205 through the threaded hole. In this way, the two sets of moving blocks 205 move inward at the same time through the threaded rotation. The bearing 204 can improve the stability of the bidirectional screw 203 during rotation, ensuring that the bidirectional screw 203 will not deviate during rotation. When the two sets of moving blocks 205 move inward, they will also drive the extrusion block 206 inward. The slider 207 slides into the groove 209 of the lifting block 208, and the lifting block 208 moves upward through the sliding connection. This causes the lifting plate 210 to rise, allowing the silicone rubber in the mold body 201 to be demolded. The demolded silicone rubber can then be removed. At this time, the reverse function of the motor 202 is turned on, which drives the bidirectional screw 203 to reverse. This causes the two sets of moving blocks 205 to move the extrusion block 206 to both sides, allowing the lifting block 208 to drive the lifting plate 210 to move downward. This is ready for the next demolding operation, avoiding manual demolding and improving demolding efficiency.

[0026] Example 2, as Figure 1 and Figure 5 As shown, a heat dissipation assembly 3 is provided inside the mold body 201. The heat dissipation assembly 3 includes a cooling chamber 301. A water pump 302 is provided on one side of the mold body 201. A water pipe 303 is connected to one side surface of the water pump 302. A cooler 304 is connected to the surface of the water pipe 303. One end of the water pipe 303 is connected to the cooling chamber 301 of the mold body 201. A cooling fan 305 is connected to the operating table 1 at a position that matches the cooler 304.

[0027] The effect achieved in Embodiment 2 is as follows: the coolant in the cooling chamber 301 can achieve rapid cooling of the mold body 201. The water pump 302 is turned on to extract the coolant in the cooling chamber 301 and transport it to the cooler 304 through the water pipe 303 for heat dissipation and cooling. Turning on the cooling fan 305 can improve the cooling effect. After cooling, the coolant will re-enter the cooling chamber 301 for cooling and reuse, which effectively improves the cooling effect.

[0028] Working principle: When it is necessary to quickly demold the silicone rubber in the mold body 201, the motor 202 can be turned on by controlling the switch, so that the two sets of moving blocks 205 move inward at the same time and squeeze the lifting block 208, so that the lifting block 208 can push the lifting plate 210 upward. The lifting plate 210 pushes the silicone rubber in the mold body 201 to achieve the effect of rapid demolding, avoiding manual demolding and improving demolding efficiency. The coolant in the cooling chamber 301 can quickly cool the mold body 201, thus achieving the purpose of rapid molding. The cooling effect is effectively improved by using water cooling in conjunction with the cooling fan 305.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
