Description

Technical Field

[0001] The utility model relates to the technical field of ornament injection moulds, in particular to an ornament injection mould which is easy to demould. Background Art

[0002] Jewelry injection mold is a special tool for manufacturing jewelry. Plastic is melted by high temperature and high pressure and then injected into the mold. After the plastic cools down, the required jewelry can be obtained. Jewelry injection mold is an indispensable and important tool in the jewelry manufacturing process. However, in the process of demolding, the current injection mold mostly adopts manual demolding to demold the equipment. The manual operation requires the staff to maintain high-intensity labor for a long time, and it is also necessary to maintain the demolding stability of the upper mold base during the demolding process to avoid damage to the injection molded parts by the upper mold base. This leads to a long production cycle of the product and a high labor intensity for the staff. Therefore, the present application provides a jewelry injection mold that is easy to demold to meet the needs. Utility Model Content

[0003] The utility model aims to provide a jewelry injection mold which is easy to demould, so as to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A jewelry injection mold that is easy to demould comprises a lower mold base; an upper mold base is installed on the top of the lower mold base, connecting brackets are symmetrically fixedly connected to both sides of the lower mold base, and side plates are fixedly connected to the top side of each connecting bracket, and a mounting cross bar is fixedly installed at one end of the two side plates, and the middle part of the mounting cross bar is rotatably connected to one end of a hydraulic cylinder;

[0006] Guide rails, two of which are fixedly mounted on one side of the side plate, a connecting frame is slidably connected between the guide rails, the four corners of the lower surface of the connecting frame are respectively fixedly connected to the top ends of four connecting rods, and the bottom ends of the four connecting rods are respectively fixedly connected to the four corners of the top end of the upper die base;

[0007] The auxiliary component is fixedly mounted on the top of the connecting frame, and the top of the auxiliary component is fixedly connected to the output end of the hydraulic cylinder.

[0008] A further improvement of the technical solution of the utility model is that the connecting bracket is arranged in a C shape, and the bottom end of the connecting bracket is provided with a bending portion which is interconnected and cooperated with the side wall of the lower mold base, so as to increase the contact area between the connecting bracket and the side wall of the lower mold base.

[0009] By adopting the above technical solution, the C-shaped connecting bracket can realize the upper and lower connection between the lower mold base and the side panel, thereby making it more convenient to assemble the parts on the equipment. The setting of the bottom end bending portion of the connecting bracket can increase the contact area between the connecting bracket and the lower mold base, thereby increasing the installation stability between the two.

[0010] A further improvement of the technical solution of the utility model is that: a plurality of lightweight grooves are provided on the connecting bracket to reduce the overall weight of the connecting bracket.

[0011] By adopting the above technical solution, the lightweight slot setting on the connecting bracket reduces the weight of the connecting bracket itself, which can reduce the weight load on the top of the equipment. In addition, while ensuring the structural strength, the production cost of the product can be reduced and the cost investment can be reduced.

[0012] A further improvement of the technical solution of the utility model is that: the guide rail is arranged in an L shape, and the two guide rails are arranged symmetrically up and down.

[0013] By adopting the above technical solution, the L-shaped guide rail can guide the connecting frame to lift up obliquely and then move horizontally. This stroke can drive the upper mold base to complete the demolding process through the connecting frame. In addition, the removal of the upper mold base can open the space at the top of the lower mold base for the staff to carry out subsequent product demolding work. In addition, the guide rails symmetrically arranged up and down can make the connecting frame slide obliquely, so that the upper mold base fixedly connected to the connecting frame slides obliquely, exposing the lower surface of the upper mold base to a greater extent in front of the staff, making it convenient for the staff to clean the lower surface of the upper mold base.

[0014] A further improvement of the technical solution of the utility model is that the connecting frame is arranged in a U-shaped shape, and reinforcing ribs are arranged at the four corners of the inner circle of the connecting frame.

[0016] A further improvement of the technical solution of the utility model is that: both ends of the connecting frame are provided with sliding protrusions that slide with the guide rails to guide the connecting frame to slide along the guide rails.

[0017] By adopting the above technical solution, the sliding protrusions at both ends of the connecting frame are convenient for increasing the sliding fit between the connecting frame and the guide rail, so that the connecting frame can slide restrictively along the guide rail, thereby realizing the demoulding process between the lower mold base and the upper mold base.

[0018] A further improvement of the technical solution of the utility model is that the auxiliary component includes a connecting support plate, two of the connecting support plates are symmetrically fixedly installed in the center of the upper surface of the connecting frame, a mounting rod is fixedly installed in the center of the top of the two connecting support plates, the middle part of the mounting rod is rotatably connected to a connecting ring, and the connecting ring is fixedly connected to the output end of the hydraulic cylinder.

[0019] By adopting the above technical solution, the connecting support plate cooperates with the mounting rod to form a triangular connection structure. The connecting support plate can increase the connection area with the upper surface of the connecting frame and increase the connection stability between the two. In addition, the mounting rod cooperates with the connecting ring to form a rotational connection with the hydraulic cylinder, so that the hydraulic cylinder pulls the connecting frame through the auxiliary component.

[0020] A further improvement of the technical solution of the utility model is that: the bottom end of the connecting support plate is symmetrically provided with connecting protrusions that are connected and matched with the connecting frame.

[0021] By adopting the above technical solution, the setting of the connecting protrusion at the bottom end of the connecting support plate can increase the connection area between the connecting support plate and the upper surface of the connecting frame, and can increase the connection stability between the two, ensuring that the equipment can operate stably.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0023] 1. The utility model provides a jewelry injection mold that is easy to demold. The guide rail provided on the equipment forms a directional track movement, so that when the connecting frame drives the upper mold base to demold, it moves a certain distance to vacate the top space of the lower mold base, which is convenient for the staff to perform the demolding operation. In addition, the guide rail cooperates with the connecting frame to form an inclined setting for the upper mold base, which can expose the lower surface of the upper mold base to the greatest extent in front of the staff, making it convenient for the staff to clean the upper mold base, thereby increasing the convenience of the equipment during demolding.

[0024] 2. The utility model provides a jewelry injection mold that is easy to demold. The connection of the equipment is completed through the auxiliary components provided on the equipment. At the same time, the injection port at the top of the upper mold base can flow out, which is more convenient for the staff to perform injection molding operations.

[0036] The auxiliary component 10 is fixedly mounted on the top of the connecting frame 8 , and the top of the auxiliary component 10 is fixedly connected to the output end of the hydraulic cylinder 6 .

After the demolding operation is completed, the hydraulic cylinder 6 restores the upper mold base 2 to its initial working position through the auxiliary component 10 to facilitate the next injection molding process.

[0040] In this embodiment, the C-shaped connecting bracket 3 can form an upper and lower installation of the lower mold base 1 and the side panel 4, which is convenient for the installation of the device, and the bending portion at the bottom end of the connecting bracket 3 can increase the connection area between the lower mold base 1 and the connecting bracket 3, thereby increasing the connection stability between the lower mold base 1 and the connecting bracket 3.

In addition, in order to increase the structural strength of the connecting frame 8, the four internal corners of the connecting frame 8 are provided with reinforcing ribs for reinforcing the structure to increase the operating stability of the equipment.

[0044] Example 4

[0045] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the auxiliary component 10 includes a connecting support plate 11, and the two connecting support plates 11 are symmetrically fixedly installed in the center of the upper surface of the connecting frame 8, and a mounting rod 12 is fixedly installed in the center of the top of the two connecting support plates 11, and a connecting ring 13 is rotatably connected to the middle part of the mounting rod 12, and the connecting ring 13 is fixedly connected to the output end of the hydraulic cylinder 6, and the bottom end of the connecting support plate 11 is symmetrically provided with connecting protrusions that are connected and matched with the connecting frame 8.

As the connecting frame 8 moves, the upper mold base 2 follows and moves synchronously. The L-shaped guide rail 7 can guide the connecting frame 8 to lift up obliquely and then move horizontally. This stroke can drive the upper mold base 2 to complete the demoulding process through the connecting frame 8. In addition, the removal of the upper mold base 2 can open the top space of the lower mold base 1 for the staff to carry out subsequent product demoulding work. In addition, the guide rails 7 symmetrically arranged above and below can make the connecting frame 8 form an inclined sliding, so that the upper mold base 2 fixedly connected to the connecting frame 8 slides obliquely, exposing the lower surface of the upper mold base 2 to a greater extent in front of the staff, which is convenient for the staff to clean the lower surface of the upper mold base 2. After the demoulding operation is completed, the hydraulic cylinder 6 restores the upper mold base 2 to the initial working position through the auxiliary component 10, which is convenient for the next injection molding process.
