Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to an internally drawn oblique pin mold structure. Background Technology

[0002] Currently, injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] When there are many internal undercuts in a normal product, a slanted pin is needed to remove the undercuts. However, in the commonly used slanted pin method, the slanted pin and the ejector pin move together to push out, which will pull the product and the slanted pin together, making it difficult to remove the product. Summary of the Invention

[0004] The purpose of this invention is to provide an internally drawn oblique pin mold structure, which solves the problem of products being difficult to remove.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an internally drawn inclined pin mold structure, including a female mold plate and a male mold plate. A hot runner plate, an upper fixing plate, and a heat insulation plate are sequentially fixed to the top of the female mold plate using hexagonal bolts. A female mold core and a male mold core are respectively fixedly installed at the bottom of the female mold plate and the top of the male mold plate. Two mold feet are fixedly provided at the bottom of the male mold core. A lower fixing plate is fixedly installed at the bottom of the two mold feet using screws. A panel is slidably installed between the two mold feet. An ejector pin is fixedly installed at the top of the panel. A base plate is connected to the bottom of the panel using countersunk screws. A cavity is formed between the female mold core and the male mold core, and an inclined pin is provided inside the cavity. The invention also includes:

[0006] A support plate is slidably installed between the male template and the mold base;

[0007] A shovel loader, which is fixedly installed on the top of the bearing plate, is used to pull the shovel horizontally and disengage the undercut;

[0008] Several opening and closing devices are disposed between the female template and the male template, and are used to lock or release the male template and the female template;

[0009] A number of equal-height screws are located between the male template and the bearing plate, and are used to limit the bearing plate, which is slidably assembled on the outside of the equal-height screws.

[0010] Preferably, a fastening machine main component is installed on one side of the male template, and a fastening machine lever and a fastening machine top rod are respectively installed on the fastening machine main component. The fastening machine lever and the fastening machine top rod respectively press and fix the male template and the panel.

[0011] Preferably, a plurality of the opening and closing devices are fixedly installed at the bottom of the mother template.

[0012] Preferably, all of the equal-height screws are threadedly connected to the male template, and the support plate is provided with a plurality of guide holes. Parts of the equal-height screws are nested inside the corresponding guide holes, and the top of the equal-height screws is provided with a limiting part with an integrally formed structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This invention utilizes a structure including a support plate and a slanted pin. The support plate moves first, causing the slanted pin to disengage from the undercut. The product remains on the male mold core and does not move with the slanted pin. After moving a certain distance, the support plate stops moving under the action of the equal-height screw. Then, the main fastening mechanism and the fastening mechanism lever act to open the male and female mold plates, allowing the product to be ejected. This separates the slanted pin from the ejector pin, facilitating product removal and preventing product damage caused by the slanted pin. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-2The mold structure with an internal inclined pin 14 includes a female mold plate 4 and a male mold plate 5. A hot runner plate 3, an upper fixing plate 2, and a heat insulation plate 1 are sequentially fixed to the top of the female mold plate 4 via hexagonal bolts. A female mold core 11 and a male mold core 13 are respectively fixedly installed at the bottom of the female mold plate 4 and the top of the male mold plate 5. Two mold feet 7 are fixedly provided at the bottom of the male mold core 13. A lower fixing plate 10 is fixedly fixed to the bottom of the two mold feet 7 via screws. A panel 8 is slidably installed between the two mold feet 7. An ejector pin 16 is fixedly installed at the top of the panel 8. A base plate 9 is connected to the bottom of the panel 8 via countersunk screws. A cavity is formed between the female mold core 11 and the male mold core 13, and an inclined pin 14 is provided inside the cavity. The mold also includes: a support plate 6, which is slidably installed between the male mold plate 5 and the mold feet 7; and an inclined pin 14 chuck 15, which is fixedly installed on the top of the support plate 6. The device is used to pull the inclined pin 14 horizontally and disengage the undercut; several opening and closing devices 12 are set between the female template 4 and the male template 5, and are used to lock or loosen the male template 5 and the female template 4; several equal-height screws 20 are located between the male template 5 and the support plate 6, and are used to limit the support plate 6. The support plate 6 is slidably assembled on the outside of the equal-height screws 20. Through the setting of the support plate 6, the inclined pin 14 and other structures, the support plate 6 moves first to drive the inclined pin 14 to disengage the undercut. The product remains on the male mold core 13 and will not move with the inclined pin 14. After moving a distance, the support plate 6 stops moving under the action of the equal-height screws 20. Then, by the action of the main fastening component 17 and the fastening block 18, the male template 5 and the female template 4 open the mold, and the product is then ejected, so that the inclined pin 14 and the ejector pin 16 move separately, which facilitates the removal of the product and prevents the product from being damaged by the inclined pin 14.

[0020] Please see Figure 2 A fastening main component 17 is installed on one side of the male template 5. A fastening block 18 and a fastening top rod 19 are respectively installed on the fastening main component 17. The fastening block 18 and the fastening top rod 19 respectively press and fix the male template 5 and the panel 8.

[0021] Please see Figure 1 Several opening and closing devices 12 are fixedly installed at the bottom of the mother template 4.

[0022] Please see Figure 2 Several equal-height screws 20 are threadedly connected to the male template 5. Several guide holes are provided on the bearing plate 6. Several equal-height screws 20 are partially nested inside the corresponding guide holes. The top of the equal-height screws 20 is provided with a limiting part with an integrally formed structure.

[0023] The specific implementation process of this invention is as follows: When the mold is opened, under the action of the opening and closing device 12, the locking block 18, and the locking rod 19, the opening and closing device 12 is used to lock the male mold plate 5 and the female mold plate 4, and the locking block and the locking rod 19 are used to lock the male mold plate 5 and the panel 8. The female mold plate 4 and the male mold plate 5 are kept in the closed state. Under the action of the injection molding machine's pulling force, the bearing plate 6 slides along the equal height screw 20, driving the inclined pin shovel 15 to move. The inclined pin shovel 15 moves downward, pulling the inclined pin 14 to move horizontally. After the inverted clamp is removed, the product remains on the male mold core 13 and will not move with the inclined pin 14. After the bearing plate 6 moves a certain distance, it stops moving under the limiting action of the equal height screw 20. Then, under the action of the clamping ejector rod 19 and the clamping block 18, the male mold plate 5 and the panel 9 are released. The male mold plate 5 and the female mold plate 4 are in the mold opening state. After the male mold plate 5 and the female mold plate 4 are opened, the ejector plate 8 and the ejector base plate 9 drive the ejector pin 16 to move under the action of the cylinder inside the injection molding machine, and eject the product.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
