Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a receiving compartment mold. Background Technology

[0002] In the design of receiving compartment molds, to meet the molding requirements of the complex internal structure of the product and to ensure the overall strength and stability of the product, the cavity depth of the mold is often designed to be relatively large. Although this deep cavity structure can ensure that the plastic melt fully fills the cavity and forms a complete product shape during the injection molding process, it brings many problems in the demolding stage after the product cools and solidifies.

[0003] When the mold is deep, the contact area between the product and the inner wall of the mold cavity increases significantly, and the friction between them also increases substantially. During the demolding process, a greater external force is required to remove the product from the cavity. This not only increases the difficulty of the demolding operation but also places higher demands on the strength and stability of the mold's demolding mechanism.

[0004] Existing receiver compartment molds mostly employ traditional ejector pins or angled ejector mechanisms for demolding. These methods have several limitations when dealing with deep-cavity molds. Ejector pins, due to their small contact area with the product, experience a large ejection force per unit area, easily leaving marks such as whitening or dents on the product surface, or even directly breaking the product. While angled ejector mechanisms can disperse the ejection force to some extent, for receiver compartment products with complex internal structures, the trajectory of the angled ejector can easily interfere with the internal structure, leading to demolding failure or product damage.

[0005] Therefore, this application develops a receiving cabin mold to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a receiving chamber mold to solve the problem of easy breakage when the product is removed in the prior art.

[0007] The technical solution of this utility model is: a receiving chamber mold, comprising: an upper mold, a middle mold and a lower mold, wherein the middle mold has a liquid inlet hole;

[0008] The middle mold includes an outer mold body, a middle mold body, and an inner cavity mold body arranged sequentially from the outside to the inside. A slidable and detachable support body is provided between the inner cavity mold body and the middle mold body, and the support body surrounds the inner cavity mold body. The support body and the middle mold body form a product.

[0009] Preferably, the support body includes a first support plate and a second support plate disposed opposite to each other, with the two first support plates located between the two second support plates.

[0010] Preferably, the outer surfaces of the first support plate and the second support plate are provided with a first protrusion, and the inner surface of the middle layer mold is provided with a second protrusion that abuts against the first protrusion, so that the first support plate and the second support plate can only move towards each other.

[0011] Preferably, the lower mold has multiple grooves on the side near the middle mold, and the multiple grooves are distributed at the edge of the lower mold. One end of the outer mold body and the middle mold body are installed in the grooves. The outer mold body includes multiple first mold bodies, and the middle mold body includes multiple second mold bodies. The first mold bodies are inserted into the grooves, and the second mold bodies are slidably disposed in the grooves and move in a direction away from the inner cavity mold body.

[0012] Preferably, both the upper mold and the middle mold are symmetrically provided with handles on both sides for moving the mold.

[0013] Preferably, the bottom surface of the lower mold is provided with a plurality of fixing holes, which are distributed at the corresponding center positions of the inner cavity mold body, the first support plate and the second support plate, for fixing the inner cavity mold body.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) The outer surfaces of the first support plate and the second support plate are provided with a first protrusion, and the inner surface of the middle mold is provided with a second protrusion that matches it. During assembly, the first protrusion and the second protrusion abut against each other, so that the first support plate and the second support plate can only move towards each other during demolding, thereby first allowing the first support plate to slide off and then allowing the second support plate to slide off, so that the stress on the product is released slowly multiple times, further reducing the possibility of product breakage.

[0016] (2) A slidable and detachable support body is provided between the inner cavity mold body and the middle layer mold body. This can balance the internal stress caused by uneven cooling and shrinkage of the product during demolding, reduce stress difference, and when the demolding mechanism applies force, the support body can evenly transfer the force to the product, avoid stress concentration, and reduce the risk of product breakage.

[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] like Figures 1-2 and Figure 5 As shown, a receiving compartment mold includes an upper mold 1, a middle mold 2, and a lower mold 3. The middle mold 2 has an inlet hole 4 for injecting molding liquid, serving as a channel for liquid injection during the receiving compartment product molding process. The middle mold 2 includes an outer mold body 21, a middle mold body 22, and an inner cavity mold body 23. A slidable and detachable support body 24 is provided around the inner cavity mold body 23 between the inner cavity mold body 23 and the middle mold body 22. The product is formed between the support body 24 and the middle mold body 22. In traditional deep molds, during demolding, the product has a large contact area with the inner wall of the mold cavity, resulting in high friction and concentrated demolding stress, which easily leads to product breakage. In this mold, during the product molding process, due to uneven cooling and shrinkage, certain internal stresses are generated. The support body 24 balances these internal stresses during demolding, reducing stress differences. When the demolding mechanism applies force, the support body 24 can also evenly transmit the force to the product, avoiding product breakage due to stress concentration.

[0026] Specifically, such as Figure 4As shown, the bottom surface of the lower mold 3 is provided with multiple fixing holes 32, and these fixing holes 32 are distributed at the center positions corresponding to the inner cavity mold body 23, the first support plate 241, and the second support plate 242, for fixing the inner cavity mold body 23. During mold assembly, the inner cavity mold body 23 is fixed by bolts passing through the corresponding fixing holes 32, so that the inner cavity mold body 23 can be accurately installed on the lower mold 3. When the mold depth is large, during the molding process, the mold will be subjected to various forces such as the high pressure of the molding liquid, the thermal stress generated by temperature changes, and the mechanical stress during mold opening and closing. If the inner cavity mold body 23 is not installed accurately, different forces will be concentrated in local areas of the mold, especially in the deeper parts such as the bottom and side walls of the mold, where the pressure is more significant, causing micro-cracks to appear in the mold. With the increase of use, the cracks will gradually expand, eventually causing the mold to break. In this embodiment, multiple fixing holes 32 are evenly distributed at the center of the relevant support structure of the inner cavity mold 23, so that the force on the inner cavity mold 23 during fixing can be evenly distributed, reducing local stress concentration, extending the service life of the inner cavity mold 23, and also ensuring the structural stability of the mold during long-term use.

[0027] In this embodiment, as Figure 2 As shown, the support body 24 includes a first support plate 241 and a second support plate 242 arranged opposite to each other. The two first support plates 241 are positioned between the two second support plates 242, forming an orderly and specific spatial layout. This allows the first support plates 241 and the second support plates 242 to cooperate within the mold, jointly supporting and stabilizing the inner cavity mold 23, thus enabling a more even distribution of various forces experienced by the mold during the molding process. When the receiving chamber mold is working, the molding liquid injected into the cavity generates significant pressure on the inner cavity mold 23. This pressure is transmitted to the support body 24 through the inner cavity mold 23. If the layout of the support body 24 is unreasonable, it may lead to excessive local stress, causing deformation or even damage to the support body 24. In this embodiment, the first support plates 241 and the second support plates 242 are arranged opposite to each other in an orderly manner, which can evenly distribute the pressure of the molding liquid onto each support plate, reducing the stress concentration on a single support plate, providing multi-directional support for the inner cavity mold 23, improving the overall load-bearing capacity of the support body 24, and thus enhancing the structural stability of the mold.

[0028] Furthermore, such as Figure 3As shown, the outer surfaces of the first support plate 241 and the second support plate 242 are each provided with a first protrusion 243. At the same time, the inner surface of the middle mold body 22 is provided with a second protrusion 244 that matches the first protrusion 243. The shape, size and position of the second protrusion 244 strictly correspond to the first protrusion 243. When the first support plate 241 and the second support plate 242 are assembled with the middle mold body 22, the first protrusion 243 can accurately abut against the second protrusion 244, so that the first support plate 241 and the second support plate 242 can only move towards each other when demolding. This allows the first support plate 241 to slide off first, and then the second support plate 242 to slide off, so that the stress on the product is released slowly and repeatedly, reducing the possibility of product breakage.

[0029] To improve the stability of the mold, such as Figure 4 As shown, multiple grooves 31 are provided on the side of the lower mold 3 near the middle mold 2, and the multiple grooves 31 are evenly and orderly arranged on the edge of the lower mold 3, providing precise positioning and stable support for the installation of the outer mold body 21 and the middle mold body 22. The outer mold body 21 is composed of multiple first mold bodies 211, and the middle mold body 22 is composed of multiple second mold bodies 221. During the mold assembly process, the first mold bodies 211 are accurately installed into the grooves 31 by insertion, so that the first mold bodies 211 and the lower mold 3 form a tight and stable connection, which can effectively withstand various external forces on the mold during operation and ensure that the position of the outer mold body 21 remains fixed. The second mold bodies 221 are installed in the grooves 31 by sliding. After the product is formed, by controlling the sliding of the second mold bodies 221, they are gradually separated from the product, reducing the pulling force and friction on the product during demolding, avoiding defects such as scratches and deformation on the product surface, and improving the surface quality and dimensional accuracy of the product.

[0030] Furthermore, handles 5 are symmetrically arranged on both sides of the upper mold 1 and the middle mold 2, serving as leverage points for operators to move the molds. This facilitates operations such as moving and adjusting the molds, thereby meeting the movement needs of the molds in different production stages and ensuring the smooth operation of the production process.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
