Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a product oblique hole spring auxiliary demoulding mechanism. Background Art

[0002] At present, in the injection molding process, a demoulding mechanism is required when the mold is ejected. The existing demoulding mechanism often uses an inclined hole as a slider with a T-type slider seat (such as Figure 1 ), and the front mold bounces, easily burning out, and has high maintenance costs. The product and the inclined hole are close together, resulting in a large space requirement inside the mold, and the mold needs to increase the signal, which makes processing more complicated.

[0003] Therefore, there is an urgent need for a product oblique hole spring assisted demoulding mechanism that can reduce the internal space requirement of the mold, thereby reducing the mold size and reducing costs. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and provide a product oblique hole spring auxiliary demoulding mechanism.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: the product oblique hole spring auxiliary demoulding mechanism is applied inside the mold to assist in demoulding, including a slider obliquely withdrawing the insert, a limit plate, an auxiliary spring and an oblique withdrawing insert pressure plate;

[0006] The limiting plate is provided with an oblique through-hole for the oblique withdrawal insert of the slider to pass through, and the bottom of the oblique through-hole is provided with a limiting step that cooperates with the oblique withdrawal insert of the slider;

[0007] The top of the obliquely drawn inlay of the slider passes through the oblique through-hole and extends above the limiting plate, and the middle part of the obliquely drawn inlay of the slider is provided with a limiting portion that can abut and cooperate with the limiting step, so as to limit the obliquely drawn inlay of the slider;

[0008] The auxiliary spring abuts against the bottom of the limiting portion to provide a rebound force;

[0009] The obliquely drawn insert pressing plate is arranged above the limiting plate and abuts against the top of the obliquely drawn insert of the sliding block, and the obliquely drawn insert pressing plate can move up and down along with the panel of the mold.

[0010] Working Principle and Beneficial Effects: Compared to existing technologies, this invention utilizes a front panel that springs open during mold opening, driving the inclined insert pressure plate upward, thereby releasing the slider and allowing the inclined insert to be lifted and moved diagonally by the rebound force of the auxiliary spring, achieving inverted ejection. This eliminates the need for the inclined hole to be very close to the product and eliminates the need for a large internal mold space, thus reducing mold size and processing costs.

[0011] Furthermore, each limiting plate corresponds to two sliders with obliquely drawn inserts.

[0012] Furthermore, the two slider oblique drawer inserts are arranged in a mirror-symmetrical manner with the center line of the limiting plate as the center.

[0013] Furthermore, the limiting plate is fixed inside the mold through a connecting piece.

[0014] Furthermore, the inclined insert pressing plate is fixed to the bottom of the panel of the mold through a connecting piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0023] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0024] like Figure 1 As shown in the prior art, due to the slider seat ( Figure 1 The largest piece (not labeled) requires too much space and is too close to the inclined hole in product 8. This requires more space inside the mold, resulting in a larger mold and higher costs. Furthermore, the existing structure requires a forming insert (the white round insert between the inclined hole and the guide block), a guide block (to ensure the forming insert has a single direction of movement), and a T-slot to produce the inclined hole. These slots primarily convert the horizontal force of the slide into the diagonal force of the forming insert. The main reason for the increased space required is the larger number of components, which occupies more space than other methods.

[0025] like Figure 2-6 As shown, the product 8 inclined hole spring auxiliary demoulding mechanism is applied inside the mold to assist in demoulding, including a slider obliquely withdrawing insert 1, a limit plate 2, an auxiliary spring 3 and an oblique withdrawing insert pressure plate 4.

[0026] Among them, the panel 5 of the mold will move upward when the mold is opened, thereby driving the inclined drawer insert pressure plate 4 to move upward, and the remaining structures of the mold are all existing technologies, and the specific operation and use are also existing technologies. The improvement of this application lies in improving the demolding mechanism inside the mold, and the other structures have not changed, so the principles of other structures of the mold will not be repeated.

[0027] The limiting plate 2 is provided with an oblique through-hole for the obliquely withdrawn insert 1 of the slider to pass through, and the bottom of the oblique through-hole is provided with a limiting step that cooperates with the obliquely withdrawn insert 1 of the slider.

[0028] In this embodiment, the limiting plate 2 is fixed to the inside of the mold (the A plate 6 of the mold is located below the panel 5 and has an injection molding space inside) by connecting parts (screws).

[0029] Preferably, each limiting plate 2 corresponds to two sliders for obliquely withdrawing inserts 1, and the two sliders for obliquely withdrawing inserts 1 are arranged in a mirror-symmetrical manner with the center line of the limiting plate 2 as the center, so as to be more stable when ejecting from the mold.

[0030] Among them, the top of the slider obliquely pulled out insert 1 extends out above the limiting plate 2 through the oblique through-hole, and the middle part of the slider obliquely pulled out insert 1 is provided with a limiting portion 11 that can abut and cooperate with the limiting step, which is used to limit the slider obliquely pulled out insert 1.

[0031] In this embodiment, the diameter of the limiting portion 11 is larger than other parts of the slider for obliquely withdrawing the insert 1 .

[0032] The auxiliary spring 3 abuts against the bottom of the limiting portion 11 to provide a rebound force;

[0033] In this embodiment, the other end of the auxiliary spring 3 abuts against the injection area 7 (a portion of the mold) inside the mold plate 6. Therefore, the auxiliary spring 3 is always in a compressed state before the mold is opened. Without external force, it will expand, thereby driving the slider to draw the insert 1 diagonally.

[0034] The obliquely drawn insert pressing plate 4 is arranged above the limiting plate 2 and abuts against the top of the obliquely drawn insert 1 of the slider, and the obliquely drawn insert pressing plate 4 can move up and down with the panel 5 of the mold.

[0035] In this embodiment, the inclined insert pressing plate 4 is fixed to the bottom of the panel 5 of the mold by connecting members (screws), so that the panel 5 can drive the inclined insert pressing plate 4 to rise.

[0036] In summary, it is precisely because of the structural improvement of the present application that the conventional large slider seat ( Figure 1 This can greatly reduce the space requirement inside the mold and reduce costs.

[0037] The parts not described in detail in this utility model are prior art, so this utility model does not describe them in detail.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0039] Although this document frequently uses terms such as slider oblique drawer insert 1, limit plate 2, auxiliary spring 3, oblique drawer insert pressure plate 4, panel 5, A-plate 6, injection molding area 7, product 8, and limit portion 11, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.

[0040] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive various other forms of products 8 under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
