[0021] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] As the technical problem mentioned in the background technology, this application proposes a water chamber fixed mold core pulling mechanism, such as Figure 1 and Figure 2 As shown, including:

[0024] An upper mold body 1, wherein the upper mold body 1 has a first space 11 therein and a first channel 12 communicating with the first space 11, and a molding space is provided at the bottom of the upper mold body;

[0025] Among them, lifting columns 13 are provided at the four corners of the bottom of the upper mold body 1, and the lifting columns 13 are connected to the lower mold body away from the end of the upper mold body 1. The top of the lower film body is also provided with a molding space. When the upper mold body and the lower film body are combined, the upper and lower molding spaces form a space for accommodating the molded product. After the product is formed, the lifting columns 13 lift the upper mold body 1 and separate it from the lower mold body to perform the demolding action.

[0026] A movable insert 2, which is arranged in the first channel 12, with one end thereof extending into the first space and the other end extending into the molding space, for product molding;

[0027] A core pulling mechanism 4, one end of which is placed in the first space 11 and connected to the end of the movable insert 2 away from the molding space, is used to drive the movable insert 2 to move along the first channel 12 away from the molded product 3 after the product is molded, until it is separated from the molded product 3.

[0028] Compared with the prior art, the present application separates the movable insert 2 and the molded product 3 by means of a core pulling mechanism 4, thereby avoiding the prior art in which the movable insert 2 and the molded product 3 are demolded as one, and then the two are manually separated, and the movable insert 2 is manually installed back into the mold, thereby improving the demolding efficiency.

[0029] In a preferred embodiment, the core pulling mechanism 4 includes a transmission assembly placed in the first space and a driving assembly driving the transmission assembly to move in a horizontal direction; the transmission assembly is slidably connected to the movable insert 2, and when the transmission assembly moves in the horizontal direction, it can drive the movable insert 2 to move in the first channel 12.

[0030] In which, the transmission component can move horizontally in the first space, while the movable insert 2 cannot move horizontally due to the restriction of the first channel 12 and can only move in the first channel 12. When the transmission component drives the movable insert 2 to move away from the molded product 3 in the first channel 12, it can be separated from the molded product 3.

[0031] In a preferred embodiment, the transmission assembly includes a horizontal portion 41 connected to the driving assembly and an oblique portion 42 connected to the horizontal portion 41 at the lowest end, and the bottom of the oblique portion 42 has an oblique groove 421; the movable insert 2 has a slider 22 matching the oblique groove 421 at the end away from the molded product 3, and when the driving assembly drives the horizontal portion 41 and the oblique portion 42 to move horizontally, the slider 22 and the oblique groove 421 move relative to each other.

[0032] Among them, please refer to Figure 2 and Figure 3As shown, the bottoms of the horizontal portion 41 and the oblique portion 42 are both in contact with the inner wall of the first space 11, and the bottom of the oblique portion 42 is recessed away from the molded product end to form the oblique slide groove 421, and the extension direction of the oblique slide groove 421 is obliquely upward, and its left end is the lowest end, which is connected to the horizontal portion 42; when the horizontal portion 41 drives the oblique portion 42 to move to the left, the slider 22 and the oblique slide groove 421 make relative movement, because the more the oblique slide groove 421 moves to the left, the higher the part matching with the slider 22, and due to the limitation of the first channel 12, when the horizontal portion 41 moves horizontally to the left, it can drive the movable insert 2 to move to the upper left along the first channel 12, thereby realizing separation from the molded product 3.

[0033] In a preferred embodiment, the oblique slide groove 421 has a T-shaped cross section in the first plane, and the first plane is perpendicular to the horizontal direction; the slider 22 is a T-shaped slider, and the T-shaped slider can be embedded in the oblique slide groove 421.

[0034] That is, the vertical section of the oblique slide groove 421 is T-shaped. During assembly, the T-shaped slider is installed from the rightmost end of the oblique slide groove 421. After assembly, the T-shaped oblique slide groove 421 and the T-shaped slider cooperate to prevent the T-shaped slider from falling off the oblique slide groove 421.

[0035] In a preferred embodiment, the direction of the extension line of the first channel forms a first angle with the vertical direction, the opening direction of the first angle is toward the molding space side, the movable insert 2 is cut away from the inclined portion 42 to form an arch structure, and the arch structure has a first arc groove 23, and the opening direction of the first arc groove 23 is toward the side close to the molded product 3.

[0036] Please refer to Figure 4 As shown, the side wall of the first arc groove 23 close to the end of the horizontal portion 41 is the blocking portion 21. During the product molding process, the molding material will flow into the first arc groove 23. After the product is molded, since the movable insert 2 extends obliquely downward, the gravity of the part of the molded product 3 placed in the first arc groove 23 will be decomposed into a force perpendicular to the plane of the blocking portion 21 and a force along the extension direction of the first channel. Therefore, if there is no core pulling mechanism 4, the top of the movable insert 2 is not fixed. During demolding, the molded product 3 will drive the movable insert 2 to be demolded together. In this application, before opening the mold, the movable insert 2 and the molded product 3 are separated by the core pulling mechanism 4, and then demolding is performed, thereby avoiding the molded product 3 and the movable insert 2 being demolded as a whole, thereby improving the demolding efficiency.

[0037] In a preferred embodiment, the upper mold body 1 also has a first opening 14 connected to the first space 11; the driving assembly includes a cylinder, the cylinder includes a cylinder body 43 placed at the first opening, and a pull rod 44 placed in the first space 11, the pull rod 44 is connected to the transmission assembly away from the end of the cylinder body 43, and the cylinder body 43 can drive the pull rod 44 to retract and retract, thereby driving the transmission assembly to move horizontally.

[0038] The first opening 14 is opened on the left side of the upper mold body 1. When the transmission assembly is connected to the pull rod 44, the transmission assembly can be placed into the first space 11 through the first opening 14. The cylinder body 43 is provided with a connecting plate near the end of the pull rod 44. The connecting plate is sleeved outside the pull rod 44. The connecting plate is detachably connected to the left end of the upper mold body 1 by bolts to complete the installation of the driving assembly.

[0039] In a preferred embodiment, a transition piece 45 is connected to the transmission assembly end close to the driving assembly end, and the transition piece 45 is connected to the pull rod 44 away from the transmission assembly end.

[0040] Among them, the horizontal portion 41 is provided with a limit groove at the end away from the oblique portion 42, and the limit groove is T-shaped in the cross section of the first plane, and the opening direction of the limit groove is toward the end of the driving assembly. The right end of the transition piece 45 is a T-block, and the T-block can be embedded in the limit groove. The pull rod 44 of the driving assembly is connected to the transition piece 45, and the transmission assembly is driven to move by driving the transition piece 45 to move left and right. The transition piece 45 is added between the transmission assembly and the driving assembly to improve the maintainability of the core pulling mechanism.

[0041] In a preferred embodiment, a cover plate 15 is provided on the top of the first space 11, and the cover plate 15 is used to improve the integrity of the core pulling mechanism.

[0042] Among them, a first groove is opened downward at the top of the upper mold body 1, and the top of the first groove extends outward along the two edges in the front and rear directions to form two bosses. The cover plate 15 is placed on the bosses and connected to the bosses by bolts. After fixing, the upper surface of the cover plate 15 and the upper surface of the upper mold body 1 are in the same plane, thereby improving the integrity of the core pulling mechanism. In addition, dust is prevented from falling into the space used for product molding.
