Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a female mold shovel-driven male mold inclined sliding block structure. Background Technology

[0002] Injection molded products such as Figure 1 As shown, the bottom of the product involves a slider-assisted angled pull structure. When designing the mold, a common method for dealing with slider-assisted angled pull structures is to add a push plate 01 to the rear mold, such as... Figure 2 As shown, the push plate is used to drive the inclined sliding block. The purely mechanical structure is relatively stable, but this requires a higher tonnage of the injection molding machine. For example, if the original plan was to use only 180 tons, now with the addition of the push plate, a 280T machine is needed, which increases the cost per unit. This increases the mold thickness, which leads to a larger tonnage of the injection molding machine, and at the same time increases the risk of mold instability.

[0003] In addition, there are also systems that use hydraulic cylinder 02 to drive the oblique sliding block, such as... Figure 3 As shown, hydraulic cylinder drive increases molding cycle and injection molding cost. Insufficient cylinder locking force during mold closing can easily result in burrs on the product.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a female mold shovel-driven male mold inclined sliding block structure. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a female mold shovel-driven male mold inclined sliding block structure, which simplifies the mold opening action, ensures the movement of the inclined sliding block in a limited space, ensures stable mold operation, and shortens the molding cycle.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a female mold shovel-driven male mold inclined sliding block structure is provided. This female mold shovel-driven male mold inclined sliding block structure includes a male mold and a female mold. The male mold and the female mold are provided with mold cores that surround and form the product cavity. A sliding block fixing seat is fixed on the male mold. A sliding block seat is slidably installed in the horizontal direction inside the sliding block fixing seat. A shovel base that drives the sliding block seat to move back and forth is slidably installed in the vertical direction on the sliding block fixing seat. The shovel base is designed to be elongated. The shovel base passes through the sliding block fixing seat and its top is fixed to the A plate of the female mold. The shovel base moves upward with the opening of the female mold. The end of the sliding block seat near the injection molded product is provided with an inclined sliding surface. An inclined sliding block is slidably installed at the inclined sliding surface. The top of the inclined sliding block is inserted into the bottom of the injection molded product and is provided with an inner forming surface.

[0007] Preferably, the inclined surface is provided with a dovetail groove, and the bottom of the inclined slider is provided with a slider part that cooperates with the dovetail groove.

[0008] Preferably, the lower part of the shovel base facing the injection molded product is provided with a driving slope, and the slider seat is provided with a slope that cooperates with it.

[0009] Preferably, the slider fixing seat is provided with a horizontal groove for placing the slider seat in the horizontal direction, and the end of the horizontal groove near the injection molded product passes through the upper surface of the slider fixing seat. The slider fixing seat is provided with a shovel base through groove in the vertical direction that communicates with the horizontal groove for placing the shovel base.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The traditional push plate and hydraulic cylinder driven shovel structure has been changed to a mold opening mechanism on the A plate that drives the shovel, which in turn drives the slider seat to finally achieve the oblique sliding out. This avoids the instability of adding push plates or hydraulic cylinders due to the oblique sliding out of the product, reduces the overall mold development cost and injection molding cost, and enhances the company's competitiveness.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 4 to 7 The embodiments of this utility model include:

[0023] A female mold shovel-driven male mold inclined sliding block structure is disclosed. This structure includes a male mold and a female mold. The male mold and female mold are provided with mold cores (not shown in the figure) that enclose and form a product cavity. A sliding block fixing seat 1 is fixed on the male mold. A sliding block seat 2 is slidably installed horizontally inside the sliding block fixing seat 1. A shovel base 3 that drives the sliding block seat 2 to move back and forth is slidably installed vertically on the sliding block fixing seat 1. The shovel base 3 is elongated and passes through the sliding block fixing seat 1 and is fixed to the A plate 4 of the female mold at its top. The shovel base 3 moves upward as the female mold opens. The end of the sliding block seat 2 near the injection molded product is provided with an inclined sliding surface 20. An inclined sliding block 5 is slidably installed at the inclined sliding surface 20. The top of the inclined sliding block 5 is inserted into the bottom of the injection molded product and is provided with an inner forming surface 50.

[0024] The slider fixing seat 1 is provided with a horizontal groove 10 for placing the slider seat 2 in the horizontal direction. The end of the horizontal groove 10 near the injection molded product passes through the upper surface of the slider fixing seat 1. The slider fixing seat 1 is provided with a shovel base through groove 11 in the vertical direction, which communicates with the horizontal groove 10 for placing the shovel base 3.

[0025] The inclined surface 20 is provided with a dovetail groove 21, and the bottom of the inclined slider 5 is provided with a slider part 51 that cooperates with the dovetail groove 21.

[0026] The lower part of the shovel base 3 facing the injection molded product is provided with a driving inclined surface 30, and the slider seat 2 is provided with a matching inclined surface. The driving inclined surface 30 moves upward with the shovel base 3, driving the slider seat 2 to move backward along the horizontal slide groove 10 in the direction away from the injection molded product, thereby driving the inclined sliding block 5 to move along the oblique downward after detaching from the injection molded product, completing the undercut demolding.

[0027] When the female mold shovel-driven male mold inclined sliding block structure of this utility model is working, the female mold opens, and the A plate 4 and the shovel base 3 move upward synchronously. At this time, the shovel base 3 drives the slider seat 2 to slide away from the injection molded product, and the inclined sliding block 5 moves along the oblique downward of the injection molded product to complete the undercut demolding.

[0028] This utility model discloses a female mold shovel-driven male mold inclined slide block structure, which simplifies the mold opening action. It solves the problem of female mold shovel driving male mold inclined slide block through a three-stage drive of female mold shovel + slide block seat + inclined slide block, ensuring the movement of inclined slide block in a limited space, ensuring stable mold operation, and shortening the molding cycle.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
