Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically to a novel slider assembly for injection molds. Background Technology

[0002] Injection molding is a process in which molten material is injected into a mold, allowing it to solidify and harden into a finished product. In the design of injection molds, it is often necessary to create two slider mechanisms with different directions of motion on a parting surface to shape the product.

[0003] In existing technologies, this can generally be achieved using a set of mechanically driven sliders and a set of hydraulically driven sliders. However, this approach has the following drawbacks:

[0004] 1. The hydraulic cylinder drive mechanism requires a lot of mold space and is not suitable for making high-cavity molds.

[0005] 2. The sequence of motion between the hydraulic cylinder-driven slider and the mechanically driven slider needs to be completed in the injection molding machine's motion program settings, which can easily lead to misoperation and damage to the mold.

[0006] Therefore, existing technologies have certain limitations. Utility Model Content

[0007] This invention was developed to solve the above-mentioned problems, and its purpose is to provide a novel slider assembly for injection molds.

[0008] This utility model provides a novel slider assembly for injection molds, characterized by comprising: a base, a first lever, a slider seat, a first slider, a second slider, a second lever, a slider core, and a spade base.

[0009] The first lever is inclined and mounted on the base. The slider seat has an oblique sliding hole, allowing the slider seat to be fitted onto the first lever and slide along the first lever. The first slider is slidably mounted on the slider seat and has an oblique waist-shaped hole, allowing the first slider to be fitted onto the first lever and slide along the first lever. The first slider has a mounting groove, and the second slider is located in the mounting groove. The second slider has a first sliding groove. The second lever is located above the first slider and slides in cooperation with the first sliding groove, allowing the second slider to slide along the second lever. The slider core is located on the side wall of the first slider, and the shovel base is used to press the first slider.

[0010] The novel slider assembly of the injection mold provided by this utility model also has the following feature: the included angle between the first lever and the base is 20°.

[0011] The novel slider assembly for injection molds provided by this utility model also has the following features: the diameter of the sliding hole and the width of the oblong hole are not less than the diameter of the first lever.

[0012] The novel slider assembly of the injection mold provided by this utility model also has the following features: the slider core is disposed on the front side wall of the first slider, and the shovel base is located behind the first slider.

[0013] In the novel slider assembly of the injection mold provided by this utility model, it can also have the following feature: the lower opening of the waist-shaped hole is located directly above the upper opening of the sliding hole.

[0014] The novel slider assembly for injection molds provided by this utility model also has the following features: a second slide groove is provided on the slider seat, and the first slider has a protrusion that slides with the second slide groove, so that the first slider is slidably disposed on the slider seat.

[0015] Functions and effects of utility models

[0016] According to the novel slider assembly of the injection mold involved in this utility model, by using a mechanical structure instead of an external hydraulic cylinder structure, when using the same injection molding machine for production, this utility model can produce a 16-cavity mold, while the hydraulic cylinder structure can only produce a 4-cavity mold, thus increasing production efficiency by 400%. Furthermore, the ingenious mechanical structure adopted in this utility model allows for controllable slider sequence during mold opening and closing, thereby greatly reducing mold damage caused by structural failure.

[0021] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0022] Example

[0023] Figure 1 This is a structural schematic diagram of the present invention. Figure 2 This is a top view of the present invention.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a slider assembly for injection molds that enables lateral core pulling and ejection, including: a base, a first lever 10, a slider seat 20, a first slider 30, a second slider 40, a second lever 50, a slider core 60, and a spade base 70. The spade base 70 is used to press the first slider 30.

[0025] like Figure 1 and Figure 2 As shown, the first lever 10 is inclined and mounted on the base. In this embodiment, the angle between the first lever 10 and the base is preferably 20°, the number of levers is preferably two, and the shape is preferably a round rod. The first lever 10 is preferably made of 1.2379 material, with a heat treatment hardness of HRC58-60, and combined with SUJ2 surface high-frequency treatment, enables oil-free, long-term continuous production.

[0026] like Figure 1 and Figure 2 As shown, the slider seat 20 has an oblique sliding hole, allowing the slider seat 20 to be fitted onto the first lever 10 and slide along the first lever 10. Preferably, the slider seat 20 is made of 1.2767 material.

[0027] like Figure 1 and Figure 2 As shown, the first slider 30 is slidably disposed on the slider seat 20. The first slider 30 has an oblique waist-shaped hole 31, so that the first slider 30 can be sleeved on the first lever 10 and can slide along the first lever 10. The first slider 30 has a mounting groove 32. Preferably, the first slider 30 is made of HRC50-52 material.

[0028] In this embodiment, the slider seat 20 is provided with a second slide groove 21, and the first slider 30 has a protrusion that slides with the second slide groove 21, so that the first slider 30 is slidably disposed on the slider seat.

[0029] In this embodiment, the diameter of the sliding hole and the width of the oblong hole 31 are not less than the diameter of the first lever 10. Furthermore, the lower opening of the oblong hole 31 is located directly above the upper opening of the sliding hole. This ensures that during mold opening, the first slider 30 has a free travel period as it moves along the first lever 10, thus preventing any displacement of the first slider 30 during this free travel.

[0030] like Figure 1 and Figure 2As shown, the second slider 40 is disposed within the mounting groove 32, and the second slider 40 has a first sliding groove 41. The second lever 50 is disposed above the first slider 30 and slides in cooperation with the first sliding groove 41, allowing the second slider 40 to slide along the second lever 50. Preferably, the second slider 40 is made of HRC50-52 material. The second lever 50 is preferably made of 1.2379 material with a heat treatment hardness of HRC58-60.

[0031] In this embodiment, the first groove 41 is preferably a dovetail groove.

[0032] like Figure 1 and Figure 2 As shown, the slider core 60 is disposed on the side wall of the first slider 30.

[0033] In this embodiment, the slider core 60 is disposed on the front side wall of the first slider 30, and the shovel base 70 is located behind the first slider 30.

[0034] When using this invention for mold closing, the second slider 40 first moves forward along the second lever 50 to its position, and then the first slider 30 moves diagonally upward along the first lever 10 to its position. When opening the mold, the first slider 30 first moves backward along the first lever 10 to its position (during this process, the second slider 40 must not be displaced), and then the second slider 40 moves back to its position along the second lever 50.

[0035] The role and effect of the embodiments

[0036] According to the novel slider assembly of the injection mold involved in this utility model, by using a mechanical structure instead of an external hydraulic cylinder structure, when using the same injection molding machine for production, this utility model can produce a 16-cavity mold, while the hydraulic cylinder structure can only produce a 4-cavity mold, thus increasing production efficiency by 400%. Furthermore, the ingenious mechanical structure adopted in this utility model allows for controllable slider sequence during mold opening and closing, thereby greatly reducing mold damage caused by structural failure.

[0037] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
