The mold frames play a supporting role in it, and the mold frames are also constantly improved and upgraded.

[0003] At present, the exhaust effect of plastic molds is poor when casting plastic products, resulting in bubbles inside the plastic products during molding, and excessive internal pressure when the mold frame is removed, which affects product quality and increases production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a mold frame with an exhaust function to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions: a mold frame with an exhaust function, comprising a bottom plate and a panel, a plurality of guide sleeves are arranged between the bottom plate and the panel, a plate A is arranged below the panel, a plate B is arranged below the plate A, a plurality of first exhaust grooves are arranged at the bottom of the plate A, a plurality of second exhaust grooves are arranged at the top of the plate B, the cross-sections of the first exhaust grooves and the second exhaust grooves are both semicircular, and the positions of the first exhaust grooves and the second exhaust grooves correspond to each other.

[0005] Preferably, sealing plugs are provided in the first exhaust groove and the second exhaust groove, and sealing rings and handles are provided at the ends of the sealing plugs.

[0006] Preferably, a mold foot is provided between the B plate and the bottom plate.

[0007] Preferably, a positioning ring is provided on the panel, and a gate sleeve is provided below the positioning ring.

[0008] Preferably, a face needle plate and a bottom needle plate are provided on the bottom plate, and a plurality of return needles are passed through the face needle plate and the bottom needle plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the utility model has a novel design, utilizes a reasonable mechanical structure, and cleverly brings into play the inherent potential of various elements. Exhaust grooves are arranged on both the A plate and the B plate to enhance the exhaust effect of the mold frame and ensure that there are no bubbles inside the product. When dismantling the mold frame, the sealing plug is removed to facilitate exhaust, facilitate dismantling of the mold frame, and ensure product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-6 The utility model provides a technical solution: a mold frame with exhaust function, including a bottom plate 1 and a panel 2, a plurality of guide sleeves 3 are arranged between the bottom plate 1 and the panel 2, an A plate 4 is arranged under the panel 2, a B plate 5 is arranged under the A plate 4, and a mold foot 7 is arranged between the B plate 5 and the bottom plate 1.

[0018] A positioning ring 81 is provided on the panel 2 , and a sprue sleeve 82 is provided below the positioning ring 81 . The positioning ring 81 is used for positioning the mold frame when it is fixed on the injection molding machine, and the injection port of the injection molding machine is installed on the sprue sleeve 82 .

[0019] The bottom plate 1 is provided with a face needle plate 91 and a bottom needle plate 92 , and a plurality of return needles 93 are passed through the face needle plate 91 and the bottom needle plate 92 , and the model is pushed up by the return needles 93 .

[0020] A plurality of first exhaust grooves 41 are provided at the bottom of the A plate 4, and a plurality of second exhaust grooves 51 are provided at the top of the B plate 5. The cross-sections of the first exhaust grooves 41 and the second exhaust grooves 51 are both semicircular, and the positions of the first exhaust grooves 41 and the second exhaust grooves 51 correspond. Therefore, when the A plate 4 and the B plate 5 are combined, the first exhaust grooves 41 and the second exhaust grooves 51 can form a circular exhaust channel, thereby enhancing the exhaust effect of the mold frame and ensuring that there are no bubbles inside the product.

[0021] A sealing plug 6 is provided in the first exhaust groove 41 and the second exhaust groove 51. The sealing plug 6 is located in a circular exhaust passage. A sealing ring 61 and a handle 62 are provided at the end of the sealing plug 6. The sealing ring 61 can ensure that the first exhaust groove 41 and the second exhaust groove 51 are in a sealed state during injection molding, thereby ensuring that the injection molding process proceeds normally. The handle 62 can facilitate the removal of the sealing plug 6 when the mold frame is removed, thereby facilitating exhaust and removing the mold frame to ensure product quality.
