Description

Technical Field

[0002] A mold for injection molding processing is a tool used for plastic molding, usually made of metal materials (such as steel or aluminum). The main function of the mold is to form the shape of the required plastic parts during the injection molding process.

[0003] An injection mold is composed of an upper mold and a lower mold. The lower mold is fixed at the required position, and a cylinder is arranged at the top of the upper mold. When in use, first drive the upper mold to move to the top of the lower mold through the cylinder, and inject materials between the two molds. After molding, then drive the upper mold and the lower mold to separate through the cylinder, and finally take out the molded injection parts from the lower mold. After the mold is used for a period of time, it needs to be regularly maintained and serviced, including cleaning, lubricating, checking for wear, etc., which requires removing the upper mold from the output end of the cylinder. However, the traditional upper mold and the output end of the cylinder are directly connected by bolts, so other tools are needed for disassembly during maintenance, which increases the difficulty of maintenance.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a mold for injection molding, as shown in Figures 1-4 Figure, which includes an upper mold 1. A lower mold 2 is arranged at the bottom of the upper mold 1. It further includes:

[0023] A fixing block 3, which is fixedly connected to the top end of the upper mold 1. A connection hole 301 is opened at the top of the fixing block 3. A positioning block 4 is inserted into the interior of the connection hole 301. A strengthening member 7 is arranged at the connection part between the upper mold 1 and the positioning block 4;

[0024] A clamping component 5, which includes clamping holes 502 symmetrically opened on the inner walls of both sides of the connection hole 301. Clamping blocks 501 for fixing the positioning block 4 and the fixing block 3 are symmetrically inserted into both sides of the positioning block 4. A moving member 6 for moving the position of the clamping block 501 is arranged on one side of the clamping block 501.

[0025] It should be noted that when the upper mold 1 needs to be installed, the positioning block 4 is directly fixed to the output end of the cylinder, then the positioning block 4 is inserted into the interior of the connection hole 301 opened on the fixing block 3, and the clamping block 501 is driven by the moving member 6 to move into the interior of the clamping hole 502, so as to fix the fixing block 3 and the positioning block 4, and complete the fixing of the upper mold 1 and the output end of the cylinder. When the upper mold 1 is installed and disassembled subsequently, the clamping block 501 can be directly driven to move by the moving member 6.

[0026] Specifically, a feeding hole 101 is opened at the top of the upper mold 1. A plurality of guiding holes 102 are symmetrically opened at the center of the bottom of the upper mold 1. A plurality of guiding rods 201 are symmetrically arranged at the center of the top of the lower mold 2. The guiding rods 201 are inserted into the interior of the guiding holes 102.

[0027] It should be noted that a forming hole is arranged between the upper mold 1 and the lower mold 2, and this hole is adapted to the feeding hole 101 and is used to inject the injection molding raw material into the interior of the forming hole during use. When the forming is completed, the upper mold 1 is removed from the top of the lower mold 2, and the formed injection molded part is taken out from the top of the lower mold 2.

[0028] Specifically, a penetrating hole 401 is opened at the top of the positioning block 4. Positioning holes 402 are symmetrically opened on the inner walls of both sides of the penetrating hole 401.

[0029] It should be noted that when the positioning block 4 needs to be fixed to the output end of the cylinder, the positioning block 4 is sleeved on the output end of the cylinder through the penetration hole 401 opened at its top, and then a bolt passes through the positioning hole 402, and the positioning block 4 is fixed to the output end of the cylinder by the bolt.

[0030] Specifically, the moving member 6 includes a connecting block 602 fixedly connected to one side of the clamping block 501. A spring 603 is arranged on one side of the connecting block 602. A plurality of cavities 601 are symmetrically opened on both sides of the positioning block 4. The connecting block 602 and the spring 603 are both inserted and connected inside the cavity 601. A penetration hole is opened on the inner wall of one side of the cavity 601, and the clamping block 501 is inserted and connected inside the penetration hole.

[0031] It should be noted that the opened cavity 601 is adapted to the arranged connecting block 602, so that the connecting block 602 can be inserted and connected inside the cavity 601. Both ends of the arranged spring 603 are fixedly connected to one side of the connecting block 602 and the inner wall of the other side of the cavity 601, and the connecting block 602 is pushed towards the side of the clamping block 501 by the spring 603.

[0032] Furthermore, when the positioning block 4 and the fixed block 3 need to be fixed, first push the clamping block 501 towards the side of the connecting block 602 and push the clamping block 501 into the penetration hole. Then insert the positioning block 4 into the connecting hole 301. When one side of the clamping block 501 is in contact with the inner wall of the connecting hole 301, release the pressing on the clamping block 501 and continue to move the position of the positioning block 4. When the clamping block 501 is aligned with the clamping hole 502, the clamping block 501 is pushed into the clamping hole 502 by the push of the spring 603, and the positioning block 4 is restricted inside the connecting hole 301 by the clamping block 501, and the positioning block 4 and the fixed block 3 are fixed.

[0033] Specifically, the reinforcing member 7 includes a reinforcing block 701 fixedly connected to the top end of the upper mold 1. A reinforcing groove 702 is opened at the bottom end of the positioning block 4, and the reinforcing block 701 is inserted and connected inside the reinforcing groove 702.

[0034] It should be noted that the arranged reinforcing block 701 is fixedly connected to the top end of the upper mold 1, and the opened reinforcing groove 702 is adapted to the arranged reinforcing block 701, so that the reinforcing block 701 can penetrate into the reinforcing groove 702. When the positioning block 4 is subjected to a pushing force towards one side, the situation of the positioning block 4 tilting towards one side is avoided by the pulling of the reinforcing block 701.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
