Description

Mould demoulding structure Technical Field The application relates to the technical field of dies, in particular to a die demoulding structure. Background In the field of mold manufacturing, along with the continuous increase of demands of industrial production on various parts, injection mold technology is widely applied and developed. The injection molding process can efficiently manufacture injection molding bodies with various shapes and sizes, and meets the requirements of different industries on product precision and quality. In the conventional demolding process of the mold, in order to take the injection molding body out of the mold, the mold is usually directly pulled out along a certain direction of the injection molding body, and the method is simple and direct and is suitable for some injection molding bodies with simpler structures. However, when some special structures of the injection molding body are processed, the mold is only moved in a single direction to perform demolding, so that the mold is easy to be clamped with structures on other surfaces of the injection molding body, the injection molding body is possibly damaged in the demolding process, the qualification rate of products is reduced, the production cost is increased, and the requirements of efficient and high-quality production cannot be met. Disclosure of utility model The application provides a mold demolding structure, which is used for solving the problem that the existing mold is easy to damage an injection molding body when moving along a single direction during demolding from the injection molding body with a special structure. A mold release structure comprising: the mold comprises a mold body, wherein the mold body is internally provided with an accommodating space and can be used for injection molding to form an injection molding body, the injection molding body is provided with a first side surface extending along the length direction and a second side surface extending along the width direction, the mold body comprises a first mold, and the first mold corresponds to the first side surface and can be moved along the width direction away from the first side surface to be demolded; And the demolding piece is arranged on the first mold and corresponds to the second side surface, and can move along the length direction far away from the second side surface when the first mold moves, and then the demolding piece and the first mold move in the same direction. Through adopting above-mentioned technical scheme, when first mould removes, the demolding piece moves along the length direction who keeps away from the second side earlier, and then moves with first mould syntropy together, has avoided the injection molding body to block and damage because of the structure on mould and the second side when drawing of patterns, can accomplish whole drawing of patterns process more smoothly, has guaranteed the integrality of injection molding body. In one embodiment, the demolding piece comprises a second mold and a first moving piece, the second mold corresponds to the second side face, the first moving piece is arranged on one side, away from the second side face, of the second mold, the second moving piece is arranged in the first mold, and the first moving piece and the second moving piece are matched to enable the demolding piece to move. Through adopting above-mentioned technical scheme, the composition structure of drawing of patterns spare has been made clear, and first moving member realizes the removal of drawing of patterns piece through the cooperation with the second moving member in the first mould for drawing of patterns structure's design and realization are more clear and operable. In one embodiment, the first moving member is a sliding block, the sliding block extends along a direction away from the first side surface and inclines towards the second side surface, the second moving member is a groove, the sliding block and the second mold are both arranged in the groove, the groove is provided with an abutting block, and the abutting block abuts against the sliding block. Through adopting above-mentioned technical scheme, the sliding block extends along keeping away from first side direction and inclines towards the second side, cooperates with the butt piece in the recess, and when first mould moved, the butt piece promoted the sliding block, makes the second mould produce along the component of keeping away from the second side direction with its inclination to realize the first separation of second mould, this kind of design is simple effective, can realize the drawing of patterns action reliably. In one embodiment, the sliding block is provided with a bump, the bump is arranged at two ends of the sliding block along the height direction and far away from the second side surface, the sliding block is in a T shape, and the abutting block abuts against the bump. Through adopting above-mentioned technical scheme, the s
