Description

Technical Field

[0001] This utility model relates to the field of silicone mold structure technology, and in particular to a silicone mold with a positioning structure. Background Technology

[0002] Silicone molds are specialized molds for making handicrafts. According to their properties, silicone mold raw materials can be divided into ordinary silicone and weather-resistant silicone. Silicone is characterized by high temperature resistance, corrosion resistance, strong tear resistance, and high simulation precision, making it suitable for making various handicrafts. When silicone molds are used for injection molding, they need to have a good positioning mechanism to prevent the mold from shaking during injection, which would affect the injection molding effect.

[0003] A search revealed that authorization announcement number CN212736717U discloses a positioning device for a silicone shell mold of a flat vulcanizing machine, relating to the field of vulcanizing machines. The device includes a base with a U-shaped plate on its top. Clamping arms are rotatably connected to both sides of the top of the U-shaped plate. The bottom of the two sets of clamping arms, on their adjacent sides, has a matching sliding groove, and a slider is slidably connected between the two sets of sliding grooves. A rotating rod is rotatably connected to the middle of the base, and the top of the rotating rod is threaded, extending into the sliding groove. This invention involves placing the mold in the groove, with a motor driving the rotating rod to rotate clockwise. The thread on the top of the rotating rod rotates accordingly, causing the slider to slide towards the bottom of the groove. During this sliding, the two sets of clamping arms rotate in opposite directions. When the clamping arms abut against the mold, the motor stops rotating, and the clamping arms clamp the mold. This simplifies the positioning process.

[0004] However, existing silicone molds have a single positioning mechanism, which results in poor positioning between molds. During the injection molding process, the molds may move, affecting the injection molding effect of the silicone. Therefore, there is an urgent need in the market for a silicone mold with a positioning structure to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a silicone mold with a positioning structure to solve the problem mentioned in the background art that the existing silicone mold positioning mechanism is simple, which makes the positioning effect between molds poor. During the injection molding process, the molds may move, thus affecting the injection molding effect of silicone.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A silicone mold with a positioning structure includes a connecting base, an injection base at the upper end of the connecting base, an upper injection mold mounted below the connecting base, positioning seats around the lower end of the upper injection mold, positioning holes inside the positioning seats, positioning blocks below both ends of the upper injection mold, a lower forming mold mounted below the upper injection mold, positioning grooves at the four corners of the lower forming mold, the positioning grooves corresponding to the positioning seats, the positioning seats located inside the positioning grooves, positioning rods mounted above the positioning grooves, a support base mounted below the lower forming mold, a top seat inside the support base, and a stabilizing seat mounted below the support base.

[0008] Preferably, the upper injection mold and the connecting seat are fixedly connected by fixing screws, and six fixing screws are provided, which are symmetrical about the vertical center line of the connecting seat.

At the same time, the positioning rod 5 is installed in the groove. The interior of the positioning hole 304 can further position the upper injection mold 3 and the lower molding mold 4 to avoid displacement during injection molding, which would affect the injection molding effect. The top seat 11 can push the ejector rod 10, which facilitates demolding. The return spring 8 can make the top seat 11 move and return to its original position after demolding. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the working principle and process of how the silicone mold is used, it will not be described in detail in this patent.

[0024] See Figures 1-4 The upper injection mold 3 has a cooling water inlet 301 at one end and a cooling water outlet 302 on one side of the cooling water inlet 301. The lower end of the upper injection mold 3 has a molding groove 305 inside. The lower molding mold 4 has a cooling water inlet 401 at one end of the outer wall and a cooling water outlet 402 on one side of the cooling water inlet 401. The upper end of the lower molding mold 4 has a molding groove 405 inside. This arrangement can cool the upper injection mold 3 and the lower molding mold 4, thereby improving the efficiency of injection molding.

[0025] See Figures 1-4There are four positioning seats 303, which are integral with the upper injection mold 3. There are two positioning blocks 306, which are symmetrical about the vertical center line of the upper injection mold 3. The positioning blocks 306 are integral with the upper injection mold 3. The two opposite outer walls of the lower forming mold 4 are provided with limiting grooves 404. The positioning blocks 306 are correspondingly set with the limiting grooves 404. The positioning blocks 306 are located inside the limiting grooves 404. The positioning blocks 306 are located inside the limiting grooves 404. This can further position the upper injection mold 3 and the lower forming mold 4, thereby avoiding relative shaking between the upper injection mold 3 and the lower forming mold 4 during injection, which would affect the injection molding effect.

[0026] Working principle: In use, the positioning rod 5 of the lower molding mold 4 is installed into the positioning hole 304 of the upper injection mold 3, which can initially position the mold. Then, the upper injection mold 3 is slid to make the positioning seat 303 located inside the positioning groove 403, which can further position the lower molding mold 4 and the upper injection mold 3, preventing the upper injection mold 3 and the lower molding mold 4 from shaking during injection, thus affecting the injection effect of silicone. During installation, the positioning block 306 of the upper injection mold 3 is located inside the limiting groove 404 of the lower molding mold 4, which can again position the upper injection mold 3 and the lower molding mold 4. The limiting rod 1 7 and the limiting rod 2 9 can position the top seat 11 when it moves to eject the material, preventing the movement from deviating and thus preventing the ejector rod 10 from ejecting the material and demolding properly.
