Description

An injection mold capable of preventing high temperature scalding

Technical Field

The utility model relates to the technical field of injection molds, and more specifically to an injection mold capable of preventing high-temperature scalding.

Background technique

Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

China Patent Authorization Announcement No.: CN218803725U discloses a mold for automobile injection molding. This solution can eject the injection molded parts from the mold cavity after the automobile injection mold is molded, reducing the possibility of damage to the injection molded parts during removal, which is beneficial to improving the quality and efficiency of demolding the injection molded parts. Auxiliary components are installed to accurately connect the upper mold and the lower mold, reducing the possibility of mold deviation, which is beneficial to improving the quality of injection molding of the injection molded parts.

In the above scheme, the injection molded part is ejected from the mold cavity by manually pushing the top plate, and then the injection molded part is taken out manually. Since the mold is usually equipped with a cooling water system to cool the plastic to solidify it, blockage or poor flow often occurs in the cooling water channel, resulting in poor cooling effect. Once the channel is blocked, it will cause uneven cooling of the injection molded part, so that some parts of the injection molded part still maintain a high temperature, increasing the risk of scalding of workers in the process of taking the injection molded part. Therefore, in view of the above problems, an injection mold that can prevent high-temperature scalding is proposed.

Example:

Please refer to Figures 1-3, an injection mold capable of preventing high temperature scalding comprises a base 1, an L-shaped plate 2 is fixedly connected to the top of the base 1, and a lower mold base 3 is fixedly connected to the top of the base 1, a cylinder 5 is installed on the top of the L-shaped plate 2, the output end of the cylinder 5 passes through the L-shaped plate 2 and is fixedly connected to the upper mold base 4, a mold cavity 10 is opened on the top of the lower mold base 3, and a material ejection component 8 is arranged inside the lower mold base 3, a material discharge component 7 is arranged on the top of the base 1, and a collection frame 9 is installed on the top of the base 1;

The blanking assembly 7 includes a first motor 71 fixed to the top of the base 1 , an output end of the first motor 71 is fixedly connected to a fixing plate 72 , and an outer end of the fixing plate 72 is provided with a pair of clamping plates 76 .

In this solution, the upper mold base 4 and the lower mold base 3 are controlled to close the mold by starting the cylinder 5. An injection port is provided at the outer end of the upper mold base 4. The injection raw material is injected into the lower mold base 3 and the upper mold base 4 through the injection port. Then, the cooling water or other cooling medium in the mold flows through the injection molded part through the cooling channel, thereby quickly reducing the temperature of the plastic and solidifying it.

Please refer to Figure 3. A slide groove is provided at the outer end of the fixed plate 72. The outer ends of a pair of clamping plates 76 are fixedly connected with sliders 75. The pair of sliders 75 are slidably connected to the slide groove. The outer end of the fixed plate 72 is fixedly connected with a second motor 73. The output end of the second motor 73 is fixedly connected with a bidirectional screw rod 74 adapted to the pair of sliders 75. The end of the bidirectional screw rod 74 away from the second motor 73 is rotatably connected to the inner wall of the slide groove.

When the ejecting assembly 8 ejects the solidified injection molded part from the mold cavity 10, the second motor 73 is started to control the bidirectional screw 74 to rotate, driving a pair of sliders 75 to approach each other, thereby clamping the injection molded part using a pair of clamping plates 76, and then the first motor 71 is started to control the fixed plate 72 to rotate 180°. When the injection molded part is located directly above the collection frame 9, the clamping of the injection molded part is released, and the injection molded part is collected in the collection frame 9. Then the unloading assembly 7 is controlled to reset, which can replace manual picking, reduce the workload of staff, and reduce the risk of high temperature burns caused by manual picking.

Among them, when in the initial state, the pair of clamping plates 76 are located on both sides of the lower mold base 3 and the upper mold base 4, and do not affect the mold clamping of the lower mold base 3 and the upper mold base 4.

Please refer to Figures 2 and 4. The ejection assembly 8 includes a top plate 81 adapted to the mold cavity 10. The outer end of the top plate 81 abuts against the inner wall of the mold cavity 10. The bottom of the top plate 81 is fixedly connected to a lifting plate 82 through a support rod. The bottom end of the lifting plate 82 is fixedly connected to a plurality of springs 83. A mounting groove is provided inside the lower mold base 3. The lifting plate 82 is slidably connected to the mounting groove. The spring 83 is fixedly connected to the inner wall of the mounting groove. A plurality of abutment columns 84 are fixedly connected to the top of the lifting plate 82. A plurality of positioning holes that are connected to the mounting groove are provided inside the L-shaped plate 2. The plurality of abutment columns 84 are respectively located in the plurality of positioning holes. A plurality of positioning columns 6 are fixedly connected to the bottom end of the upper mold base 4. The plurality of positioning columns 6 correspond one by one to the positions of the plurality of positioning holes.

When the upper mold base 4 and the lower mold base 3 are molded together, the positioning column 6 at the bottom end of the upper mold base 4 is inserted into the positioning hole, thereby squeezing the abutment column 84, so that the lifting plate 82 and the top plate 81 move downward, and at the same time compress the spring 83 to move the top plate 81 to the bottom of the inner cavity of the mold cavity 10. After the upper mold base 4 and the lower mold base 3 are molded together, they are cooled and solidified, and then the cylinder 5 is used to control the upper mold base 4 to move upward. At this time, the lifting plate 82 is acted upon by the elastic force of the spring 83, so that the top plate 81 moves upward in the mold cavity 10, and the injection molded part is ejected from the mold cavity 10, and then the injection molded part is placed in the collection frame 9 by the blanking assembly 7.

Among them, the highest height of the top plate 81 is level with the top of the lower mold base 3. At the same time, through the cooperation between the positioning column 6 and the positioning hole, the lower mold base 3 and the upper mold base 4 can be accurately connected, which reduces the deviation of the mold and is beneficial to improving the injection quality of the injection molded parts.

Working principle: When the upper mold base 4 and the lower mold base 3 are molded together, the positioning column 6 at the bottom end of the upper mold base 4 is inserted into the positioning hole, thereby squeezing the abutment column 84, so that the lifting plate 82 and the top plate 81 move downward, and at the same time compress the spring 83 to move the top plate 81 to the bottom of the inner cavity of the mold cavity 10. After the upper mold base 4 and the lower mold base 3 are molded together, they are cooled and solidified, and then the cylinder 5 is used to control the upper mold base 4 to move upward. At this time, the lifting plate 82 is acted on by the elastic force of the spring 83, so that the top plate 81 moves upward in the mold cavity 10, and the injection molded part is removed from the mold cavity. 10, then start the second motor 73 to control the bidirectional screw rod 74 to rotate, drive a pair of sliders 75 to approach each other, so that the injection molded part is clamped by a pair of clamping plates 76, and then start the first motor 71 to control the fixed plate 72 to rotate 180°. When the injection molded part is located directly above the collection frame 9, the clamping of the injection molded part is released, so that the injection molded part is collected in the collection frame 9, and then control the unloading component 7 to reset, which can replace manual picking, reduce the workload of the staff, and reduce the risk of high temperature burns caused by manual picking.

The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
