Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and specifically relates to an injection molding mold with an opening mold limit structure. Background Art

[0002] The molding of plastic products is completed by the cooperation of an injection molding machine and an injection molding mold. After the product is molded in the mold, the mold needs to be opened to take out the molded product and waste. Nowadays, in the context of the in-depth development of full automation and intelligent digitalization, these tasks are basically completed by the cooperation of intelligent equipment and manipulators. The traditional mold structure is designed for the manual operation stage and can no longer meet the requirements of fully automatic and intelligent digital production lines. As shown in the figure, during the mold opening process, the A plate and the sprue plate need to be opened so that the manipulator can reach in to take out the waste (as Figure 1 ), and the A plate and the B plate also need to be opened to facilitate the manipulator to reach in to take out the molded product (as Figure 2 ).

[0003] However, when the A plate and the sprue plate are pulled apart, the B plate also separates from the A plate. During this process, due to inertia, the A plate will retreat towards the sprue plate, resulting in no space for the manipulator to enter and unable to take out the waste.

One side of the fixed plate is provided with a spacer plate, one end of the spacer plate is provided with a B plate, four corners of one end of the panel are respectively provided with guide rods, the outside of the guide rods is movably sleeved with a sprue plate, and the outside of the guide rods on one side of the sprue plate is sleeved with an A plate;

[0006] One set of diagonal corners on both sides of the spacer plate are fixedly connected with first connecting rods through bolts, one set of diagonal corners on both sides of the panel are fixedly connected with second connecting rods through bolts, a bayonet is opened at a position near the edge at the upper end of the second connecting rod, one set of diagonal corners on both sides of the A plate are respectively connected with a clamping block through a connecting pin, the clamping block can swing around the connecting pin, and the clamping block is movably clamped with the bayonet.

[0007] Preferably, one set of diagonal corners on both sides of the B plate are respectively connected with first supporting pins, and the first supporting pins are located below the first connecting rods.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1, by Figures 3 - 6 The utility model comprises a fixed plate 1 and a panel 2, a spacer plate 3 is installed on one side of the fixed plate 1, a B plate 4 is installed on one end of the spacer plate 3, a guide rod 5 is installed on the four corners of one end of the panel 2, a nozzle plate 6 is movably sleeved on the outside of the guide rod 5, and an A plate 7 is sleeved on one side of the nozzle plate 6 and located on the outside of the guide rod 5;

[0023] A group of diagonal corners on both sides of the partition plate 3 are fixedly connected to the first connecting rod 8 by bolts, a group of diagonal corners on both sides of the panel 2 are fixedly connected to the second connecting rod 9 by bolts, and a bayonet 10 is provided at the upper end of the second connecting rod 9 near the edge, and a group of diagonal corners on both sides of the A plate 7 are connected to the clamping block 12 by the connecting pin 11, and the clamping block 12 can swing around the connecting pin 11, and the clamping block 12 is movably connected with the bayonet 10;

[0024] A set of diagonally opposite corners on both sides of the B plate 4 are connected with first supporting pins 13, and the first supporting pins 13 are located at the lower part of the first connecting rod 8. The first supporting pins 13 can play an auxiliary supporting and positioning role for the first connecting rod 8;

[0026] Working principle: During the mold opening process, the block 12, one end of which is hinged to the A plate 7 through the connecting pin 11, falls due to inertia and engages with the bayonet 10 provided on the second connecting rod 9, one end of which is fixed to the panel 2. The bayonet 10 is designed at the end away from the panel 2, which ensures that the A plate 7 is limited after being pulled open during mold opening and will not retreat due to inertia; when closing the mold, the first connecting rod 8, one end of which is fixed to the partition plate 3 behind the B plate 4, will approach the block 12 from another direction and lift the block 12 to disengage it from the bayonet 10 position, thereby releasing the limit and facilitating mold closing.
