Description

Technical Field

[0001] The utility model discloses an easy-to-release mold, belonging to the field of molds. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping and other methods.

[0003] When using existing molds, most of them are placed horizontally, so under the action of gravity, the object fits closely with the lower mold after molding. Therefore, when demolding, after removing the upper mold, it still takes a lot of effort to peel the molded object off the lower mold, resulting in low production efficiency.

[0004] An easy-to-release mold is now proposed to solve the problem of difficult mold demoulding. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an easy-to-release mold.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an easy-to-release mold, including an upper mold plate and a lower mold plate, the upper mold plate is formed with an upper injection molding path, the side of the lower mold plate abutting against the upper mold plate is formed with a lower injection molding path matching the upper injection molding path, the inner wall of the lower injection molding path is provided with a plurality of demolding parts, one end of the demolding part is rotatably connected to the lower mold plate, a pushing block is formed on the side of the free end of the demolding part away from the lower injection molding path, the upper mold plate is fixedly provided with an abutting block which can abut against the side of the pushing block away from the abutting surface of the lower mold plate and the upper mold plate, the upper mold plate can slide away from the lower mold plate and prompt the demolding part to rotate in the direction away from the lower injection molding path.

[0007] The utility model is further configured as follows: the pushing block is rotatably connected to the demoulding member, and a rotating member is provided on one side of the pushing block close to the abutting surface between the lower template and the upper template, which can rotate the pushing block toward the inner direction of the lower template.

[0008] The utility model is further configured as follows: the rotating member includes a fixed plate, a backing plate and a rotating plate, the fixed plate is fixedly connected to the demolding member, the rotating plate is fixedly connected to the pushing block and is rotatably connected to the fixed plate, a backing plate is fixedly provided on one side of the fixed plate close to the pushing block, and the backing plate abuts against one side of the rotating plate close to the pushing block.

[0009] The utility model is further configured that: the abutment block can abut against a side of the rotating plate away from the pushing block.

[0010] The utility model is further configured as follows: the lower template is formed with a plurality of limiting columns, and the upper template is formed with limiting holes matched with the limiting columns.

[0011] The utility model is further configured as follows: an air delivery cavity is formed in the limiting column, and the adjacent air delivery cavities are interconnected to form an air pressure channel, and the air pressure channel is formed by the upper air channel formed on the upper template and the lower air channel formed on the lower template.

[0012] The utility model is further configured as follows: the upper mold plate is formed with an injection hole communicating with the external space and the internal space of the upper injection channel.

[0013] Compared with the prior art, the beneficial effect of the utility model is as follows: when the product is in use, after the operator completes the molding, the operator operates the upper template to slide away from the lower template, and continuously inputs gas into the air supply channel, so that high pressure is formed in the air pressure channel, prompting the upper template to slide away from the lower template, so that the operator does not need to consume too much energy in the process of separating the upper template and the lower template. In the process of the upper template sliding away from the lower template, the abutment block abuts against the pushing block, and prompts the demolding member to rotate toward the upper template, so that the molded object is driven away from the surface of the lower injection molding channel. At this time, the molded object can be taken because it is only in contact with the demolding member at the contact point, and the demolding member rotates and extends out of the lower injection molding channel at this time, so that the operator can not only take it conveniently, but also complete the demolding operation without consuming any effort.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an easy-to-release mold of the present embodiment comprises an upper template 1 and a lower template 2, the upper template 1 is formed with an upper injection molding path 3, the side of the lower template 2 abutting against the upper template 1 is formed with a lower injection molding path 4 matching with the upper injection molding path 3, a plurality of demolding parts 5 are provided on the inner wall of the lower injection molding path 4, one end of the demolding parts 5 is rotatably connected to the lower template 2, a pushing block 6 is formed on the side of the free end of the demolding parts 5 away from the lower injection molding path 4, the upper template 1 is fixedly provided with an abutting block 7 which can abut against the side of the pushing block 6 away from the abutting surface of the lower template 2 and the upper template 1, the upper template 1 can slide away from the lower template 2 and cause the demolding parts 5 to rotate in the direction away from the lower injection molding path 4.

[0022] When the product is in use, the operator can operate the upper template 1 to slide away from the lower template 2 after molding is completed, so that the abutment block 7 abuts against the push block 6, thereby driving the demolding member 5 to rotate away from the lower template 2. At this time, the molded object is driven to rotate and thus peeled off the lower injection molding path 4. At this time, since the molded object partially extends out of the lower injection molding path 4 and only the contact part with the demolding member 5 is in contact, the operator can hold the part of the molded object outside the lower injection molding path 4 with his hand to completely separate the object from the lower template 2, thereby solving the problem of the existing mold that the object is easy to fit with the lower template during demolding, resulting in difficulty in demolding.

[0023] like Figure 4 and Figure 5As shown, the pushing block 6 is rotatably connected to the demoulding member 5, and a rotating member that can rotate the pushing block 6 toward the inner direction of the lower template 2 is provided on the side of the pushing block 6 close to the abutting surface of the lower template 2 and the upper template 1, and the rotating member includes a fixed plate 8, a butt plate 9 and a rotating plate 10, the fixed plate 8 is fixedly connected to the demoulding member 5, the rotating plate 10 is fixedly connected to the pushing block 6 and rotatably connected to the fixed plate 8, a butt plate 9 is fixedly provided on the side of the fixed plate 8 away from the pushing block 6, the butt plate 9 abuts against a side of the rotating plate 10 close to the pushing block 6, and the abutting block 7 can abut against a side of the rotating plate 10 close to the pushing block 6.

[0024] When the product is in use, during installation, the upper template 1 slides towards the lower template 2, so that the bottom of the abutment block 7 abuts against the top of the rotating plate 10, and pushes the rotating plate 10 to rotate. When sliding to the rotating plate 10 and rotating to a vertical state, the abutment block 7 does not abut against the rotating plate 10, and slides into the lower template 2. When the upper template 1 slides to the mating abutment with the lower template 2, the bottom surface of the upper template 1 abuts against the end of the rotating plate 10 rotating away from the lower template 2. Because this end of the rotating plate 10 is rounded, the rotating plate 10 can be driven to rotate to a horizontal state during the sliding of the upper template 1 to complete the installation. During demoulding, the upper template 1 is operated to slide away from the lower template 2, causing the abutment block 7 to abut against the pushing block 6. Because the setting of the abutment plate 9 makes the pushing block 6 unable to rotate in the direction away from the lower template 2, causing the demoulding member 5 to rotate in the direction away from the lower template 2 during the upward sliding of the abutment block 7, thereby completing the demoulding operation.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lower template 2 is formed with a plurality of limit columns 11, the upper template 1 is formed with limit holes 12 matched with the limit columns 11, and an air delivery cavity 13 is formed in the limit columns 11. Adjacent air delivery cavities 13 are interconnected to form an air pressure channel, and the air pressure channel is formed by the upper air channel 14 formed on the upper template 1 and the lower air channel 15 formed on the lower template 2. The upper template 1 is formed with an injection hole 16 connecting the external space with the internal space of the upper injection channel 3.

[0026] When the product is in use, during installation, the limiting hole 12 of the upper template 1 can be aligned with the limiting column 11 for sliding cooperation, so as to prevent the upper template 1 from incorrectly cooperating with the lower template 2, resulting in errors in the molded object. After the installation is completed, an air pipe that can absorb and deliver air is installed on the top of the limiting column 11. After the installation is completed, the air pipe can be operated to inhale the air delivery cavity 13, so that a negative pressure state is formed in the air pressure channel, so that the upper template 1 is tightly fitted with the lower template 2 under the action of atmospheric pressure, and then molten raw materials are injected into the interior along the injection hole 16, so that the molded object of this product will not have molding errors due to loose cooperation. When demolding, the air pipe can be operated to input high-pressure gas into the air delivery cavity 13 first, so that the air pressure channel is filled with high-pressure gas, thereby promoting the separation of the upper template 1 and the lower template 2, and after the separation, the high-pressure gas can continuously flow along the surfaces of the upper template 1 and the lower template 2 to the molded object, cool the object, and help the operator to avoid being scalded when picking it up, thereby solving the problem of difficulty in separating the mold after molding.
