Description

Technical Field

[0001] This utility model belongs to the field of sealing gasket production technology, and specifically relates to an injection mold for making sealing gaskets. Background Technology

[0002] An injection mold for making gaskets is a tool specifically designed for producing gaskets through the injection molding process. The mold typically consists of two parts: a moving mold and a fixed mold. When they are closed, they form a cavity, which is the shape of the product. Plastic raw material is injected into this cavity after being heated to a molten state. After cooling and solidification, the desired gasket product is formed. This type of mold can efficiently and accurately mass-produce gaskets of various shapes and sizes.

[0003] Existing injection molds for making gaskets work by driving a moving mold to close with a fixed mold. When they close, they form a cavity, which is the shape of the gasket. Plastic raw material is injected into this cavity after being heated to a molten state. After cooling and solidifying, it forms the desired gasket product. Then, the moving mold is driven away from the fixed mold. At the same time, the operator places a collection container at the bottom of the moving mold. Then, the formed gasket is ejected by the ejector pin and falls into the collection container. Each operation requires the manual placement of the collection container, which increases the physical burden on the operator. Frequent manual operation can easily lead to worker fatigue, especially in large-scale production, affecting work efficiency. Moreover, the operator needs to approach the mold area after the mold opens and before ejection to place the container, which poses a risk of being pinched or bumped by moving parts (such as the moving mold and ejector pins). Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an injection mold for making sealing gaskets. It can automatically demold the ejected sealing gaskets and collect them. Furthermore, it can be quickly removed from inside the mold for easy material handling, thus improving the efficiency of sealing gasket production. Operators do not need to approach the mold area when dangerous actions such as mold opening and closing or ejection occur, eliminating the main risks of mechanical injury and burns.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an injection mold for making sealing gaskets, including a frame plate, a plurality of guide pillars are arranged inside the frame plate, a moving mold is slidably arranged between the outer arc surfaces of the plurality of guide pillars, a plurality of top pillars are slidably arranged inside the moving mold, a fixed mold is arranged on the right side of the inner wall of the frame plate, the moving mold and the fixed mold are positioned correspondingly to each other, an injection tube is arranged in the injection hole opened at the upper end of the fixed mold, a rectangular frame is arranged inside the frame plate, a plurality of limiting pillars are arranged inside the rectangular frame, a receiving box is slidably arranged between the outer arc surfaces of the plurality of limiting pillars, a moving mechanism for driving the receiving box to move is arranged inside the rectangular frame, the moving mechanism includes a lead screw rotatably arranged inside the rectangular frame, the lower end of the receiving box is threadedly connected to the lead screw, a motor is arranged on the rear side of the rectangular frame, and the output shaft of the motor is connected to the rear end of the lead screw through a coupling.

[0006] As a further improvement of this utility model, a connecting plate is provided on the left side of the moving mold, and an electric push rod is provided inside the connecting plate. A square frame is provided between the left ends of multiple top pillars. The telescopic end of the electric push rod is connected to the left side of the square frame. An installation plate is provided at the upper end of the moving mold. Multiple sliding pillars are slidably arranged inside the installation plate. An auxiliary plate is provided between the lower ends of the multiple sliding pillars. An electric push rod is provided at the upper end of the installation plate. The telescopic end of the electric push rod is connected to the upper end of the auxiliary plate.

[0007] As a further improvement of this utility model, multiple mounting brackets are provided on the left and right sides of the frame plate respectively. The frame plate and the mounting brackets are fixed together by welding. Multiple mounting holes are provided inside the multiple mounting brackets.

[0008] As a further improvement of this utility model, a hydraulic push rod is provided on the left side of the inner wall of the frame plate, and the telescopic end of the hydraulic push rod is connected to the left side of the moving mold.

[0009] As a further improvement of this utility model, a circulating cooling pipe is provided inside the fixed mold.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by controlling the operation of the external hydraulic control cabinet, and then by controlling the operation of the electric push rod, the telescopic end drives the top column on the square frame to move to the right, fixing the sealing ring on the moving mold so that it falls into the inside of the receiving box. Then, by controlling the operation of the motor, the sealing ring inside the receiving box moves forward out of the mold under the restriction of the limit columns on both sides, making it easy for personnel to retrieve the material. The ejected sealing gasket can be automatically demolded and collected, and can also be quickly removed from the inside of the mold for easy retrieval by personnel. This improves the efficiency of sealing gasket production. Operators do not need to approach the mold area when dangerous actions such as mold opening and closing and ejection occur, eliminating the main risks of mechanical injury and burns.

[0012] Secondly, by controlling the operation of the electric push rod, the telescopic end drives the auxiliary plate to move downward under the restriction of the sliding column. The auxiliary top column peels off the sealing gasket and demolds it, allowing it to fall quickly into the receiving box for collection, further improving the production efficiency of the sealing gasket.

[0013] Thirdly, the mounting holes on the mounting bracket can be used to fix the gasket with bolts, ensuring the stability of the gasket during injection molding and improving the injection molding quality of the sealing ring. Attached Figure Description

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 2As shown in Figures 3 and 5, an injection mold for making a sealing gasket includes a frame plate 101. Multiple guide pillars 102 are arranged inside the frame plate 101. A moving mold 103 is slidably arranged between the outer arc surfaces of the multiple guide pillars 102. Multiple ejector pillars 208 are slidably arranged inside the moving mold 103. A fixed mold 104 is arranged on the right side of the inner wall of the frame plate 101. A circulating cooling pipe 107 is arranged inside the fixed mold 104. An injection pipe 105 is arranged in an injection hole at the upper end of the fixed mold 104. A rectangular frame 201 is arranged inside the frame plate 101. Multiple limiting pillars 204 are arranged inside the rectangular frame 201. A receiving box 202 is slidably arranged between the outer arc surfaces of the multiple limiting pillars 204. A moving mechanism for driving the receiving box 202 is arranged inside the rectangular frame 201. A hydraulic push rod 106 is arranged on the left side of the inner wall of the frame plate 101. The telescopic end of the hydraulic push rod 106 is connected to the left side of the moving mold 103.

[0023] like Figure 2 , 3 As shown in Figure 4, the moving mechanism includes a lead screw 203 rotatably disposed inside a rectangular frame 201. The lower end of the receiving box 202 is threadedly connected to the lead screw 203. A motor 209 is disposed on the rear side of the rectangular frame 201. The output shaft of the motor 209 is connected to the rear end of the lead screw 203 through a coupling. A connecting plate 205 is disposed on the left side of the moving mold 103. An electric push rod 206 is disposed inside the connecting plate 205. A square frame 207 is disposed between the left ends of multiple top columns 208. The telescopic end of the electric push rod 206 is connected to the left side of the square frame 207. An mounting plate 303 is disposed on the upper end of the moving mold 103. Multiple sliding columns 302 are slidably disposed inside the mounting plate 303. An auxiliary plate 304 is disposed between the lower ends of the multiple sliding columns 302. An electric push rod 301 is disposed on the upper end of the mounting plate 303. The telescopic end of the electric push rod 301 is connected to the upper end of the auxiliary plate 304.

[0024] First, connect the circulating cooling pipe 107 to the external cooling circulation mechanism. Then, connect the inlet and outlet oil pipes of the hydraulic push rod 106 to the external hydraulic control cabinet. Next, open the external hydraulic control cabinet by control. The extension end of the hydraulic push rod 106 drives the moving mold 103 to move to the right and close with the fixed mold 104 under the sliding restriction of the guide column 102. Then, inject the plastic raw material heated to the molten state into the cavity formed by the moving mold 103 and the fixed mold 104 through the injection pipe 105. Then, open the cooling circulation mechanism by control, so that the cooling water enters the interior of the fixed mold 104 through the circulating cooling pipe 107 to cool the plastic raw material inside and form it into a sealing gasket.

[0025] Then, by controlling the operation of the external hydraulic control cabinet, the extension end of the hydraulic push rod 106 drives the formed sealing gasket inside the fixed mold 104 to move to the left (due to the cooling on one side of the fixed mold 104, the sealing ring remains on the moving mold 103 with a higher temperature). Then, by controlling the operation of the electric push rod 206, the extension end drives the top column 208 on the square frame 207 to move to the right, fixing the sealing ring on the moving mold 103 so that it falls into the inside of the receiving box 202. Then, by controlling the operation of the motor 209, the output shaft drives the lead screw 203 to rotate, so that the sealing ring inside the receiving box 202 moves forward out of the mold under the restriction of the limit columns 204 on both sides, making it easier for personnel to pick up the material.

[0026] When the top column 208 ejects and demolds the sealing gasket, the electric push rod 301 can be activated by control. The telescopic end drives the auxiliary plate 304 to move downward under the restriction of the sliding column 302. The auxiliary top column 208 peels and demolds the sealing gasket, allowing it to fall quickly into the receiving box 202 for collection.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, multiple mounting brackets 108 are provided on the left and right sides of the frame plate 101, and multiple mounting holes are provided inside the mounting brackets 108. The mounting brackets 108 can be fixed by bolts through the mounting holes to ensure the stability of the sealing gasket during injection molding.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
