Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and relates to an injection mold for connecting soft rubber to a folding laundry basket. Background Technology

[0002] The main function of a folding laundry basket is to store laundry, keeping the home clean and hygienic. When not in use, the basket can be folded away for storage, saving space. Since laundry baskets are typically made of plastic, they can be produced using injection molding. In existing technology, the injection mold first heats the plastic raw material to a molten state, then injects it into a pre-designed molding cavity. Once the cavity is full, the mold is rapidly cooled, causing the molten plastic to solidify and form the desired laundry basket. Using injection molding to produce plastic products offers advantages such as high precision and high efficiency.

[0003] To optimize the folding structure of the laundry basket and make it easier to fold, the laundry basket can be divided into two parts: an upper shell and a lower shell. A soft rubber structure can then be installed between the upper and lower shells to connect the two shell parts and form a complete frame structure. The lower shell can be moved and inserted into the upper shell to achieve the folding function. Therefore, it is necessary to improve the internal structure of the injection mold so that the soft rubber structure connecting the upper and lower shells can be formed inside the mold. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the current technology by proposing an injection mold for connecting soft rubber to a folding laundry basket. The technical problem to be solved by this invention is: how to improve the internal structure of the injection mold.

[0005] The objective of this utility model can be achieved through the following technical solution: An injection mold for connecting soft rubber to a folding laundry basket includes a top plate, a fixed template, a movable template, and a bottom plate arranged in sequence. The top of the movable template is provided with an upwardly protruding mounting plate. The mounting plate can be slidably inserted into the bottom of the fixed template. The two sides of the mounting plate and the fixed template can respectively enclose to form a first mounting cavity and a second mounting cavity. An upper shell is provided inside the first mounting cavity, and a lower shell is provided inside the second mounting cavity. A connecting cavity is also provided between the mounting plate and the fixed template. The two ends of the connecting cavity are respectively connected to the first mounting cavity and the second mounting cavity. A guide slope is provided on the bottom side of the fixed template near the mounting plate. A plurality of limiting blocks are provided on the top of the movable template. The limiting blocks abut against the bottom of the upper shell and the lower shell respectively.

[0006] In this design, since the materials of the upper and lower shells are different from those of the soft rubber, the upper and lower shells need to be manufactured in advance. Before the moving mold plates close, the upper and lower shells are installed on both sides of the mounting plate, respectively. Then, the moving mold plates are moved to close the mold, allowing the upper and lower shells to enter the first and second mounting cavities, respectively. High-temperature molten soft rubber is then injected into the connecting cavity. Because the two ends of the connecting cavity are connected to the first and second mounting cavities, the molten rubber can flow and wrap around the side walls of the upper and lower shells, allowing the cooled and molded soft rubber to connect the upper and lower shells. Through the above method, the structure of setting a limiting block at the top of the moving mold plate can easily install the upper and lower shells on both sides of the mounting plate, and ensure that the upper and lower shells will not fall off during the mold closing process. The guide slope at the bottom of the fixed mold plate can contact the top of the upper and lower shells and push them to fit against the mounting plate, improving the injection molding accuracy.

[0007] In the injection mold for the connecting soft rubber of the aforementioned folding laundry basket, the bottom of the moving template near the first mounting cavity is provided with a downwardly recessed clearance groove, and a limiting block is also provided inside the clearance groove. The clearance groove is used to adapt to the structure on the upper shell, so that the upper shell can be more easily installed onto the mounting plate.

[0008] In the injection mold for the folding laundry basket connecting soft rubber, the base plate has several slidingly connected push rods. The tops of the push rods slide through the moving template and extend to the bottom of the first and second mounting cavities, respectively. After the moving template separates from the fixed template, the push rods move upward and push out from the bottom of the first and second mounting cavities, pushing the upper shell, lower shell, and soft rubber to demold.

[0009] In the injection mold for the connecting soft rubber of the aforementioned folding laundry basket, the bottom of the base plate is provided with several fixed cylinders, each of which is connected to a push rod. The cylinders serve as a driving mechanism to push the push rods upward.

[0010] In the injection mold for the connecting soft rubber of the aforementioned folding laundry basket, the second mounting cavity is smaller than the first mounting cavity, and the connecting cavity has an inclined structure, tilting towards the side where the second mounting cavity is located. Since the lower shell is smaller than the upper shell, the second mounting cavity is correspondingly smaller than the first mounting cavity, thus the soft rubber also has an inclined structure, facilitating folding.

[0011] In the aforementioned injection mold for the soft plastic connector of the folding laundry basket, a feed inlet is provided on the top plate, and a nozzle is connected to the bottom of the feed inlet. The bottom of the nozzle is connected to the connecting cavity. Molten plastic heated to a molten state is injected from the feed inlet and then injected into the connecting cavity through the nozzle at the bottom.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, since the two ends of the connecting cavity are connected to the first mounting cavity and the second mounting cavity, the molten liquid can flow and wrap around the side walls of the upper and lower shells, so that the cooled and molded soft rubber can connect the upper and lower shells to form a complete folding laundry basket product.

[0014] 2. In this solution, the structure of setting a limiting block at the top of the moving template can easily install the upper and lower shells onto the two sides of the mounting plate respectively, and ensure that the upper and lower shells will not fall off during the mold closing process. The guide slope at the bottom of the fixed template can contact the top of the upper and lower shells and push the upper and lower shells to fit against the mounting plate, thereby improving the injection molding accuracy.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1 As shown, the injection mold for connecting soft rubber to a folding laundry basket includes a top plate 1 at the top, a fixed template 2 fixedly connected to the bottom of the top plate 1, a slidingly connected movable template 3 at the bottom of the fixed template 2, a bottom plate 4 fixedly connected to the bottom of the movable template 3, a feed port 1a on the top plate 1, and a downwardly recessed clearance groove 3b on the top of the movable template 3.

[0022] like Figure 2As shown, the moving template 3 has an upwardly protruding mounting plate 3a at its top. The mounting plate 3a can be slidably inserted into the bottom of the fixed template 2. The two sides of the mounting plate 3a and the fixed template 2 can respectively enclose a first mounting cavity 5 and a second mounting cavity 6. A connecting cavity 7 is also provided between the mounting plate 3a and the fixed template 2. The two ends of the connecting cavity 7 are respectively connected to the first mounting cavity 5 and the second mounting cavity 6. The second mounting cavity 6 is smaller than the first mounting cavity 5. The connecting cavity 7 has an inclined structure and is inclined towards the side where the second mounting cavity 6 is provided. The bottom of the feed inlet 1a is provided with a connected nozzle 1b. The bottom of the nozzle 1b is connected to the connecting cavity 7. The bottom of the fixed template 2 near the mounting plate 3a is provided with a guide slope 2a. The clearance groove 3b is provided with an upwardly protruding limiting block 3c inside.

[0023] like Figure 3 As shown, the base plate 4 is provided with several slidingly connected push rods 4a. The top of the push rods 4a slides through the moving template 3 and extends to the bottom of the first mounting cavity 5 and the second mounting cavity 6 respectively. The mounting plate 3a is provided with an upper shell 8 and a lower shell 9 on both sides respectively. The top of the moving template 3 is also provided with a limiting block 3c. The limiting block 3c abuts against the bottom of the upper shell 8 and the lower shell 9 respectively.

[0024] The working principle of this solution is as follows: Figure 1-3 As shown, before the moving template 3 closes with the moving template 3, the upper shell 8 and the lower shell 9 are respectively installed on both sides of the mounting plate 3a. Through the support of the limiting block 3c, it is ensured that the upper shell 8 and the lower shell 9 will not fall off the mounting plate 3a during the mold closing process. Then the moving template 3 is moved to close the mold. The guide slope 2a can contact the top of the upper shell 8 and the lower shell 9 and push the upper shell 8 and the lower shell 9 to fit against the mounting plate 3a, so that the upper shell 8 and the lower shell 9 enter the first mounting cavity 5 and the second mounting cavity 6 respectively.

[0025] The molten soft rubber, heated to a molten state, is injected into the feed port 1a and then into the connecting cavity 7 through the nozzle 1b. Since the two ends of the connecting cavity 7 are connected to the first mounting cavity 5 and the second mounting cavity 6, the molten rubber can flow and wrap around the side walls of the upper shell 8 and the lower shell 9, so that the cooled and formed soft rubber can connect the upper shell 8 and the lower shell 9. Finally, the moving template 3 is separated from the fixed template 2, and the push rod 4a is driven to move upward, so that the upper shell 8 and the lower shell 9 are separated from the mounting plate 3a, making it easy to remove the formed laundry basket.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
