[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with strong pressure bearing capacity. Background Art
[0002] An injection mold is a tool used in the production of plastic products. It heats the plastic material to a molten state, injects it into the mold through an injection molding machine, and then cools it to form a product of the desired shape and size. The design and manufacture of injection molds is a key link in ensuring the precision, appearance and production efficiency of plastic products.
[0003] For example, the utility model with application number CN201921717807.1 belongs to the field of injection mold technology, and is particularly an injection mold that is easy to dissipate heat. The injection mold of the utility model can cool the mold from the outside and the inside at the same time by means of a cooling fan and a cooling channel, and has high cooling efficiency and high plastic part molding efficiency. After the upper mold and the lower mold are closed, they are further stabilized by a manual auxiliary stabilization component to avoid shaking of the mold during the injection molding process, thereby improving stability and the quality of plastic parts. However, the existing injection mold needs to apply external force when closing the mold to make it close together. After closing the mold for a long time, the mold is easily deformed and has low pressure-bearing capacity, which affects subsequent use.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an injection mold with strong pressure bearing capacity is provided. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection mold with strong pressure-bearing capacity, comprising a lower module and an auxiliary component, a side fixing plate is installed on the outer side of the lower module, and an auxiliary component for increasing the pressure-bearing capacity and the connection tightness is arranged on the surface of the lower module, and the auxiliary component comprises a steel pad, a mounting block, a reinforcement rod, a hydraulic rod and a support block, a mounting block is arranged on the outer side of the steel pad, and a reinforcement rod is installed on the inner side of the mounting block through a rotating shaft, and a hydraulic rod is arranged on the upper end of the side of the reinforcement rod, and the fixed end of the hydraulic rod is connected to the support block.
[0007] Furthermore, an upper module is arranged at the upper end of the lower module, and positioning rods 2 are installed at the four corners of the upper module.

[0009] Furthermore, a forming block is installed in the middle of the lower end of the upper module, and the forming block and the center point of the forming cavity are located on the same vertical line.
[0010] Furthermore, positioning holes are provided at the four corners of the lower module, and a cooling component for cooling the injection molding is arranged inside the lower module.
[0011] Furthermore, the lower module and the positioning holes are an integrated structure, and there are four positioning holes.

[0014] The utility model provides an injection mold with strong pressure bearing capacity, which has the following beneficial effects:
[0015] 1. The utility model increases the mold-closing pressure-bearing capacity of the mold by means of a steel pad at the contact surface between the lower module and the upper module, thereby increasing the mold-closing pressure-bearing capacity and alleviating the deformation of the mold. The T-shaped reinforcement rod can rotate in the mounting block. When the mold is closed, the reinforcement rod rotates to the inside of the support block, and the extension of the hydraulic rod exerts a downward pushing force on the reinforcement rod, thereby promoting the tightness of the mold closing between the lower module and the upper module.
[0016] 2. The utility model uses the side fixing plate to fix the lower module. The molding cavity and the molding block can be injected into the mold after the mold is closed. The second positioning rod is installed in the positioning hole in the mold for positioning the mold. The rectangular cooling groove has a large area and promotes injection molding at the bottom of the molding cavity, reducing molding time. The support column avoids deformation of the cooling groove.

DETAILED DESCRIPTION
[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0022] like Figure 1 As shown, an injection mold with strong pressure-bearing capacity includes a lower module 1 and an auxiliary component 3. A side fixing plate 2 is installed on the outer side of the lower module 1, and the side fixing plate 2 is used to fix the lower module 1. An upper module 4 is arranged on the upper end of the lower module 1, and two positioning rods 7 are installed at the four corners of the upper module 4. The two positioning rods 7 are installed in the positioning holes 9 in the mold clamping for positioning the mold. A molding cavity 5 is opened in the middle part of the interior of the lower module 1, and positioning rods 6 are opened on both sides of the interior of the molding cavity 5. A molding block 8 is installed in the middle part of the lower end of the upper module 4. The molding cavity 5 and the molding block 8 can be injected into the interior after the mold is closed. The center points of the molding block 8 and the molding cavity 5 are located on the same vertical line. Positioning holes 9 are opened at the four corners of the lower module 1. The lower module 1 and the positioning holes 9 are an integrated structure, and the number of positioning holes 9 is set to four.
[0023] like Figure 2 As shown, an auxiliary component 3 for increasing the pressure bearing capacity and connection tightness is arranged on the surface of the lower module 1, and the auxiliary component 3 includes a steel pad 301, a mounting block 302, a reinforcement rod 303, a hydraulic rod 304 and a support block 305. The mounting block 302 is arranged on the outer side of the steel pad 301. The steel pad 301 increases the mold clamping pressure bearing capacity at the contact surface between the lower module 1 and the upper module 4, so that the mold has an increased pressure bearing capacity when the mold is clamped, and the deformation of the mold is alleviated. A reinforcement rod 303 is installed on the inner side of the mounting block 302 through a rotating shaft. The T-shaped reinforcement rod 303 can rotate in the mounting block 302. When the mold is closed, the reinforcement rod 303 rotates to the inner side of the support block 305, and a hydraulic rod 304 is provided on the upper end of the side of the reinforcement rod 303. The fixed end of the hydraulic rod 304 is connected to the support block 305. The extension of the hydraulic rod 304 exerts a downward pushing force on the reinforcement rod 303, thereby promoting the tightness of the mold closing between the lower module 1 and the upper module 4.
[0024] like Figure 3As shown, the interior of the lower module 1 is provided with a cooling component 10 for cooling the injection molding, the cooling component 10 includes a cooling trough 1001 and a support column 1002, and the support column 1002 is installed inside the cooling trough 1001, the rectangular cooling trough 1001 has a large area to promote injection molding at the bottom of the molding cavity 5 and reduce the molding time, the support column 1002 prevents the deformation of the cooling trough 1001, the cooling component 10 also includes a water inlet pipe 1003 and a drain pipe 1004, the front side of the cooling trough 1001 is provided with a water inlet pipe 1003, and the rear side of the cooling trough 1001 is provided with a drain pipe 1004, the water inlet pipe 1003 and the drain pipe 1004 are used together for the entry and discharge of cooling water in the cooling trough 1001.
[0025] In summary, the injection mold with strong pressure bearing capacity is first based on Figure 1-Figure 3 As shown in the structure, during injection molding, the upper module 4 is hoisted by a hanger just above the lower module 1. During mold closing, the positioning rod 27 is inserted into the positioning hole 9 so that the molding block 8 is located inside the molding cavity 5. At this time, the steel pad 301 increases the mold closing pressure bearing capacity of the mold at the contact surface between the lower module 1 and the upper module 4, so that the mold pressure bearing capacity is increased during mold closing and the deformation of the mold is alleviated. Then, the T-shaped reinforcement rod 303 is rotated in the mounting block 302 to the inner side of the support block 305 so that the surface of the reinforcement rod 303 contacts the output end of the hydraulic rod 304. At this time, the hydraulic rod 304 is controlled to extend to push the reinforcement rod 303 downward, thereby promoting the tightness of the mold closing between the lower module 1 and the upper module 4. Injection molding is performed through the injection port. The rectangular cooling groove 1001 at the bottom of the molding cavity 5 promotes injection molding, reduces molding time, and improves processing efficiency.
