Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a novel ejection module of an injection mold. Background Art

[0002] Injection molds are usually installed on injection molding machines and are widely used in various industries, such as automobile manufacturing, electronic product manufacturing, medical device manufacturing, etc. The principle of injection molding is to inject liquid rubber into the mold cavity through pressure, and the rubber solidifies or solidifies to form a product. The product is taken out after the injection mold is opened.

[0003] The demoulding mechanism is an important part of the injection mold. Its demoulding method is generally the ejector part at the lower end of the fixed mold. During the injection molding process, the ejector is used to eject the plastic product from the mold to ensure that the product can be smoothly separated from the mold. The existing ejector demoulding method is to move up along the same plane to the gap, and then other external components move to drive the product in the gap to achieve final demoulding and removal. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model includes a carrying plate 1, a fixed die seat 2 is fixed on the upper end of the carrying plate 1, a lower die cavity 3 is arranged in the middle of the fixed die seat 2, and the upper end of the lower die cavity 3 is communicated with the outside; at least two groups of ejection modules 4 are arranged at the lower end of the carrying plate 1, and the multiple groups of ejection modules 4 are arranged at intervals below the lower die cavity 3; the ejection module 4 includes a pushing unit 5, and a push plate 6 is arranged on the output end of the pushing unit 5, and a plurality of push rods 7 are arranged on the stacking plate, and the push rods 7 sequentially penetrate the carrying plate 1 and the base upward and extend into the lower die cavity 3; wherein, the upper part of the fixed die seat 2 has a symmetrical inclined surface 8 that is inclined downward along the outer side, and a plane 9 is provided between the inclined surface 8 and the lower die cavity 3.

[0020] This design is an improvement on the fixed die set, with the purpose of completing the automatic removal of the molded product by demoulding through the ejection module 4.

This technology is different from the traditional ejection module 4 in that the product is ejected at the same level. Instead, through two or more groups of ejection modules 4, by setting different telescopic heights of the output ends, the push rod 7 thereon will be in an inclined state. When a certain inclination is reached, the product will slide obliquely. The injection molded product can be a base or a panel to slide down, and the sliding direction is also along the left or right side, sliding down through the inclined surface 8 at the upper part of the fixed mold base 2, thereby realizing the automatic blanking function.

[0022] There is a plane 9 between the inclined surface 8 and the lower mold cavity 3, and a support column 10 is provided on the inclined surface 8. A patch block 11 is provided on the upper end of the support plate. The upper end surface of the patch block 11 is in the same straight line as the plane 9. The main function of this design is to cooperate with the injection mold to complete the injection molding in the mold cavity.

[0023] In order to increase the contact with the injection molded product, a support block 12 is provided at the upper end of the push rod 7. At the same time, in order to form the injection molded product in the lower mold cavity 3, a positioning groove 13 for accommodating the support block 12 is provided at the bottom of the lower mold cavity 3.
