Problems solved by technology
[0003] In the prior art, in order to eject the product, the mold parts in the X, Y, and Z directions are all connected with power parts, which requires complex actions of multi-directional opening, which greatly reduces the production capacity of the same size mold. Occupies more space, and when the mold parts in the X, Y, and Z directions are uncoordinated, the rubber parts are likely to be dragged and become waste products

Embodiment Construction
[0028] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] Such as figure 1 Shown, a kind of product that the present invention can process, product orientation and figure 2 , image 3 The mesocavity is in the opposite direction. The product has a concave-convex structure in the X, Y, and Z directions, forming an undercut; the mold must be set into several parts, that is, the cavity must be divided into several parts and set on several mold parts. When the several mold parts are spliced, Cavity composition. After the product is injection molded, in order to take out the product, several mold parts need to be opened away from the product, and the product remains on one of the mold parts.
[0030] Such as figure 2 , image 3 , Figure 5 to Figure 9 As shown, an injection mold includes an upper mold core 1 and a support 2 arranged below the upper mold core 1, and also includes...

The invention discloses an injection mold. The injection mold comprises an upper die core, a support, a left mold core, a second sliding block and a first sliding block. A right first die core and a right second die core are arranged on the second sliding block. The upper die core, the left mold core, the right first die core and the right second die core are spliced to obtain a mold with a cavity. One of the upper die core and the first sliding block is connected with an inclined rod, and the other is provided with an inclined hole matched with the inclined rod. The rising of the upper die core relative to the support can drive the first sliding block to slide rightward. The right first die core and the right second die core are both connected with the first sliding block through a sliding block chute structure. The sliding of the first sliding block to the right first drives the right first die core and the right second die core to be away from each other and then drives the second sliding block to be away from the left mold core through the sliding block chute structure. One power realizes the coordinated separation of mold parts in X, Y and Z directions. The product is easy todemold, the quality is guaranteed, and the production capacity is improved.
Description
technical field [0001] The invention relates to the field of injection molding, in particular to an injection mold applied to products with multiple undercuts. Background technique [0002] In actual production, some products have undercuts in X, Y, and Z directions due to their complex shapes. [0003] In the prior art, in order to eject the product, the mold parts in the X, Y, and Z directions are all connected with power parts, which requires complex actions of multi-directional opening, which greatly reduces the production capacity of the same size mold. It takes up more space, and when the mold parts in the X, Y, and Z directions are uncoordinated, it is easy to cause the rubber parts to be dragged and become waste products. [0004] Therefore, it is necessary to set up a mold and a power to realize the coordinated separation of mold parts in the X, Y, and Z directions, so that the product can be easily demoulded, the quality is guaranteed, and the production capacity ...
