Problems solved by technology

[0002] In the production of existing molds, many adopt the inclined roof structure, but if the product has a large contact area with the inclined roof and the side wall of the product is thin, during the demoulding process, due to the product ejection and the separation of the product from the contact surface with the inclined roof at the same time Occurs, so that the thinner part of the side wall of the product bears the force on both sides at the same time, making the thinner part of the side wall prone to deformation and strain, and the demoulding effect is poor, resulting in a high defective rate of the product

Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0021] The following will refer to the attached Figure 1-3 The invention will be described in detail in conjunction with the embodiments.

[0022] Such as Figure 1-2 Shown, a kind of ejection structure of intake manifold slant top, comprises front mold 1, back mold 2, movable mold kernel 3, slant top 4 and ejector mechanism 5, described front mold 1, described back mold 2 and A mold cavity 6 is formed between the movable mold cores 3, and a product 7 is formed in the mold cavity 6. The top surface of the inclined roof 4 is bonded to the front mold 1, and one side of the inclined roof 4 is connected to the product. 7 fit, the other side of the inclined roof 4 fits with the movable mold core 3.

[0023] Such as Figure 2-3 As shown, the ejection mechanism 5 includes an ejection block 51 and an ejection f...

Abstract

The invention provides an oblique top ejection structure of an intake manifold. The oblique top ejection structure of the intake manifold comprises a front mold, a rear mold, a movable mold core, an oblique top and an ejection mechanism, wherein a mold cavity is defined by the front mold, the rear mold and the movable mold core, and a product is positioned in the mold cavity; the top face of the oblique top is jointed with the front mold; one side face of the oblique top is jointed with the product, and the other side face of the oblique top is jointed with the movable mold core; the ejectionmechanism comprises an ejection block and an ejection fixing block, wherein the ejection block passes through the ejection fixing block in a sliding way and penetrates through the interior of the oblique top. The oblique top ejection structure enables the ejection of the thinner part of the side wall of the product and the separation between the product and an oblique top contact surface to be performed separately, thus preventing the product from being subjected to the force acting on both sides at the same time when the product is released from the molds, and enabling the thinner part of theside wall of the product not to be easily deformed after demoulding.

Description

technical field [0001] The invention belongs to the structural technical field of molds, and in particular relates to an intake manifold inclined ejection structure. Background technique [0002] In the production of existing molds, many adopt the inclined roof structure, but if the product has a large contact area with the inclined roof and the side wall of the product is thin, during the demoulding process, due to the product ejection and the contact surface of the product and the inclined roof are separated at the same time Occurs, so that the thinner side wall of the product bears the force on both sides at the same time, making the thinner side wall prone to deformation and strain, the demoulding effect is poor, and the defective rate of the product is high. Contents of the invention [0003] In view of this, the present invention aims to propose an intake manifold inclined top ejection structure, so that the ejection of the product with a larger contact area and the ...
