Technical Field

[0001] The invention relates to the field of inclined spring block ejection mechanisms, in particular to an inclined spring block ejection mechanism for a front mold of a mold. Background Art

[0002] In the mold, the mold bevel block is installed on the bottom mold or the top mold, such as the inclined ejector mechanism, which is often used in the mold to form the inner concave and convex of the molded plastic part, and has the ejection function. Its installation position depends on the specific mold design and molding requirements. In some cases, the mold bevel block can be installed on the top mold to complete the lateral molding or ejection action during the ejection process, but when the mold bevel block is ejecting the molded part, there will be sticking between the molded parts, which will hinder the demolding. Summary of the invention

[0003] The purpose of the present invention is to solve the problem in the prior art that when the mold bevel block is ejecting the molded part, the molded parts may stick to each other, which hinders demoulding, and proposes a mold front mold bevel spring block ejection mechanism.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a mold front mold oblique spring block ejection mechanism, including a module installation cavity, two pairs of oblique guide rails and two mold oblique blocks, the two pairs of oblique guide rails are symmetrically fixed and inserted in the module installation cavity, the two mold oblique blocks are respectively slidably connected with the two pairs of oblique guide rails, and the two mold oblique blocks have multiple mold cavities at opposite locations, and also include: two pairs of elastic support members, the two pairs of elastic support members are arranged between the inner wall of the module installation cavity and the two mold oblique blocks; two blowing assemblies, the two blowing assemblies They are respectively arranged on the two oblique mold blocks, and the two blowing assemblies each have multiple air jets, multiple blocking blocks and an air blowing assembly. The multiple air jets are opened on the inner wall of the mold cavity, and the blocking blocks are plugged and blocked at the air jets, and the ends of the blocking blocks are in the same plane as the mold cavity plane, and the air blowing assembly is connected with the air jets; two linkage assemblies, the two linkage assemblies are used to respectively link the blocking blocks on the two oblique mold blocks to move and cancel the blocking of the air jets during the process of the mold oblique block moving obliquely on the oblique guide rail to eject.

[0005] Specifically, the mold has two matched first mold bodies and a second mold body, the first mold body has a module installation cavity, the module installation cavity is used to install the mold bevel block, through the mold closing action of the first mold body and the second mold body, the mold bevel block can be squeezed, so that the two mold bevel blocks compress the first elastic support member to achieve mold closing, and then the mold cavities on the two mold bevel blocks are docked to form a closed cavity, and the closed cavity is then aligned with the mold body on the second mold body to form a complete mold body; It should be further explained that a space for the oblique guide rail is provided in the mold body of the second mold body.

[0006] It should be understood that during the separation of the first mold body and the second mold body, under the elastic push of the first elastic support member, the mold bevel block will move in the oblique direction a under the guidance of the oblique guide rail and move out of the module installation cavity, so that the two mold bevel blocks in the mold closing state move away from each other. During the process of the two mold bevel blocks moving away from each other and moving on the oblique guide rail, the two linkage components respectively link the blocking blocks on the two mold bevel blocks to move and cancel the blocking of the air jet, and the air blowing component will spray air into the air jet, thereby blowing the formed molded part, so that when the two mold bevel blocks are just separated, gas will be ejected from the air jet and blow the mold cavity, so that the molded part The vibration is generated, which is conducive to promoting the rapid separation of the molded part and the mold cavity, and is conducive to preventing the molded part from being continuously pulled by the mold bevel block and causing warping. In the process of the blocking block moving away from the molded part, since the contact area between the blocking block and the molded part is small, it can be achieved to first achieve local rapid separation, and the local contact area of ​​the blocking block is small, which is easy to separate, and after separation from the inner wall of the mold cavity, the overall contact area of ​​the inner wall of the mold cavity and the molded part is quickly reduced, which is conducive to reducing the possibility of adhesion to the molded part when the mold cavity continues to move, and under the impetus of the airflow, the separation of the sticking parts between the inner wall of the mold cavity and the molded part is further promoted.

[0007] In one embodiment, a connecting cavity is opened on the inner wall of the mold cavity at the position of the blocking block, and a mounting part supporting the blocking block is fixedly installed in the connecting cavity, and the mounting part includes: a mounting shell, which is arranged in the connecting cavity and has a first ventilation cavity connected to the air jet; a port, which is opened at the end of the first ventilation cavity; the blocking block slider is arranged in the first ventilation cavity, and the blocking block has a blocking end that fits the port, and the blocking block moves away from the port, passes through the mounting shell and extends to the outside of the mounting shell to be connected with the air blowing assembly.

[0008] It should be understood that by setting the port, the sealing end is fully fitted with the port, which is beneficial to increase the contact area between the sealing block and the end of the first ventilation cavity, and is beneficial to further improve the sealing of the sealing. In addition, by setting the port, the sealing position of the sealing block can be limited to keep it in the same plane as the inner wall of the mold cavity.

[0009] In one embodiment, a through opening is provided at the surface where the blocking end fits the port, a second ventilation cavity is provided inside the blocking block, the second ventilation cavity is connected to the inflation assembly, and an air outlet connected to the first ventilation cavity is provided on the side wall of the second ventilation cavity. It should be understood that when the blocking block is in a blocking state, the through opening will be blocked by the inner wall of the port, and when the blocking block moves away from the air jet under the linkage of the linkage assembly, the through opening will be away from the inner wall of the port and unblocked, so that the through opening is connected to the air jet under the connection of the first ventilation cavity, thereby forming a connection between the first ventilation cavity, the air outlet, the through opening and the air jet, forming a channel for the inflation assembly to inflate air into the mold cavity.

[0010] In one embodiment, the linkage assembly includes: a linkage cavity, which is opened on the surface of the mold bevel block; two guide grooves, which are opened on the surface of the same pair of inclined guide rails, and both of the guide grooves have a first inclined surface and a first vertical surface; a linkage plate, which is located in the linkage cavity and between the blocking block fixed on the same mold bevel block and one end of the mounting shell; two push plates, which are fixedly connected to the two ends of the linkage plate and are both inserted through the same mold bevel block, and the ends of the two push plates are respectively inserted in the guide grooves of the same pair of inclined guide rails; two support wheels, which are respectively rotatably connected to the ends of the two push plates and are respectively in rolling contact with the first vertical surfaces of the two guide grooves; two second elastic support members, one end of each of the two second elastic support members is respectively installed on the end of the two push plates away from the support wheel, and the other end is in contact with the inner wall of the linkage cavity.

[0011] It should be understood that when the module oblique block is out of the module installation cavity, the second elastic support member is in a state of being compressed by the push plate, and at this time, the end of the push plate is supported by the support wheel and the first vertical surface; During the movement of the mold bevel block, the mold bevel block will drive the pushing plate to move, and the pushing plate will drive the supporting wheel to move away from the first vertical plane. Under the push of the second elastic support member, the pushing plate drives the supporting wheel to move to the first inclined plane, and the pushing plate will drive the blocking block to move while moving, so that the blocking block drives the blocking end away from the port, automatically canceling the blockage of the jet port.

[0012] Compared with the prior art, the present invention has the following beneficial effects: According to the present invention, when the two mold bevel blocks move away from each other and on the inclined guide rail, the two linkage components respectively link the blocking blocks on the two mold bevel blocks to move and cancel the blocking of the air jet, and the air blowing component will spray air to the air jet, thereby blowing the formed molded part, so that when the two mold bevel blocks are just separated, gas is ejected from the air jet and blows the mold cavity, causing the molded part to vibrate, which is beneficial to promote the rapid separation of the molded part and the mold cavity, and is beneficial to prevent the molded part from being continuously pulled by the mold bevel blocks and causing warping.

[0013] When the blocking block moves away from the molded part, the blocking block can be quickly detached locally because of the small contact area with the molded part. The blocking block is easily detached because of the small contact area with the molded part. After separation from the inner wall of the mold cavity, the contact area between the inner wall of the mold cavity and the molded part is quickly reduced, which helps to reduce the possibility of sticking to the molded part when the mold cavity continues to move. The separation of the sticking parts between the inner wall of the mold cavity and the molded part is further promoted by the push of the airflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It should be understood that during the separation of the first mold body 1 and the second mold body 2, under the elastic push of the first elastic support member, the mold bevel block 5 will move in the oblique direction a under the guidance of the oblique guide rail 4, and move out of the module installation cavity 3, so that the two mold bevel blocks 5 in the mold closing state move away from each other. During the process of the two mold bevel blocks 5 moving away from each other and moving on the oblique guide rail 4, the two linkage components respectively link the blocking blocks 8 on the two mold bevel blocks 5 to move and cancel the blocking of the air jet 7, and the air blowing component will spray air into the air jet 7, thereby blowing the formed molded part, so that when the two mold bevel blocks 5 are just separated, gas is ejected from the air jet 7, and the mold cavity 6 is blown, so that the formed part The vibration of the molded part is conducive to promoting the rapid separation of the molded part and the mold cavity 6, and is conducive to preventing the molded part from being warped due to continuous pulling of the mold bevel block 5.

[0033] like Figures 3 to 7 As shown, in one embodiment, a connecting cavity 9 is opened at the position of the sealing block 8 on the inner wall of the mold cavity 6, and a mounting part supporting the sealing block 8 is fixedly installed in the connecting cavity 9, and the mounting part includes: a mounting shell 10, the mounting shell 10 is arranged in the connecting cavity 9, and has a first ventilation cavity 11 connected to the air jet 7; a port 12, the port 12 is opened at the end of the first ventilation cavity 11; the blocking block 8 slider is arranged in the first ventilation cavity 11, and the blocking block 8 has a blocking end 13 that fits the port 12, and the blocking block 8 moves away from the port 12, penetrates the mounting shell 10 and extends to the outside of the mounting shell 10 to be connected with the air blowing assembly.

[0034] It should be understood that by setting the port 12, the sealing end 13 is completely fitted with the port 12, which is beneficial to increase the contact area between the sealing block 8 and the end of the first ventilation cavity 11, and is beneficial to further improve the sealing performance of the plugging. In addition, by setting the port 12, the sealing position of the sealing block 8 can be limited to keep it on the same plane as the inner wall of the mold cavity 6.

[0035] like Figures 3 to 5As shown, in one embodiment, a through hole 1301 is provided at the surface where the blocking end 13 and the port 12 are in contact, a second ventilation cavity 34 is provided inside the blocking block 8, the second ventilation cavity 34 is connected to the air blowing component, and a gas outlet 3401 connected to the first ventilation cavity 11 is provided on the side wall of the second ventilation cavity 34.

[0036] like Figures 8 to 14 As shown, in one embodiment, the linkage assembly includes: a linkage cavity 14, which is opened on the surface of the mold oblique block 5; two guide grooves 15, which are opened on the surface of the same pair of oblique guide rails 4, and both guide grooves 15 have a first inclined surface 1501 and a first vertical surface 1502; a linkage plate 16, which is located in the linkage cavity 14 and fixed between the blocking block 8 on the same mold oblique block 5 and one end of the mounting shell 10; two push plates 17, which are fixedly connected to Both ends of the linkage plate 16 are inserted through the same mold bevel block 5, and the ends of the two push plates 17 are respectively inserted in the guide grooves 15 of the same pair of inclined guide rails 4; two support wheels 18, the two support wheels 18 are respectively rotatably connected to the ends of the two push plates 17, and are respectively in rolling contact with the first vertical surfaces 1502 of the two guide grooves 15; two second elastic support members, one end of the two second elastic support members is respectively installed at one end of the two push plates 17 away from the support wheel 18, and the other end is in contact with the inner wall of the linkage cavity 14.

[0037] It should be understood that when the module oblique block 5 is out of the module installation cavity 3, the second elastic support member is compressed by the push plate 17. At this time, the end of the push plate 17 is supported by the support wheel 18 and the first vertical surface 1502.

The gas enters the first main pipe after passing through the one-way valve 27 and is drained into the first pipe 25 through the second pipe 26. Then, the air storage bag 24 that has released the gas is inflated again to replenish the gas in time and store the gas for the inflation assembly.

[0045] like Figure 8 In one embodiment, the oblique guide rail 4 is fixedly installed in the mold cavity 6 by bolts, and the end is fixedly connected to the limit plate 30. It should be understood that by setting the limit plate 30, the movement range of the mold oblique block 5 on the oblique guide rail 4 is limited to prevent the mold oblique block 5 from detaching from the oblique guide rail 4.

[0046] like Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, a plug-in slot 31 is provided on the inner wall of the communication cavity 9, a plug-in slider 32 is plugged into the plug-in slot 31, the plug-in slider 32 is fixedly connected to the side wall of the mounting shell 10, and a blocking plate 33 is bolted to the opening of the communication cavity 9.
