Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a mold structure for quickly changing mold cores. Background Art

[0002] The mold structure is an important tool for producing injection molded products. Injection molded products need to be formed and demolded in the mold structure. The existing mold structure generally includes an upper mold and a lower mold. After the upper mold and the lower mold are combined, the upper mold groove and the lower mold groove are matched to form a cavity.

[0003] Among them, a mold structure disclosed in the application publication number "CN115401881A" is also an increasingly mature technology. During demolding, the demolding tool is placed on the upper surface of the lower mold core, and the positioning sleeve and the positioning pin can play a positioning role for the demolding tool to prevent the demolding tool from moving in the horizontal direction during the demolding process, ensuring that the demolding protrusion of the demolding tool can remain aligned with the injection molded product during the entire demolding process, ensuring that the injection molded product is completely demolded, and avoiding the demolding tool from being crushed.

[0004] However, the device still has the following defects: when the above-mentioned equipment is in use, since the existing mold does not have a relatively quick setting for replacing the mold core, when the mold core needs to be replaced quickly, the existing mold cannot be replaced quickly, which affects the use of the mold. Utility Model Content

[0009] In order to prevent the fixed plate from affecting the movement of the clamping plate and the arc plate, as a preferred mold structure for quick mold core change of the utility model, both sides of the fixed plate are open, the opening shape of the side of the fixed plate matches the shape of the end of the arc plate, and the end of the first telescopic rod is connected to the back side of the clamping plate.

[0010] In order to prevent the connection of the arc plate from being disconnected under the action of the clamping block when the arc plate moves, as a preferred mold structure for quick mold core change of the utility model, the arc plate is provided with a groove at the connection with the clamping block, and the shape of the groove matches the two ends of the clamping block.

[0011] In order to improve the stability of the mold when the mold core is replaced, as a preferred mold structure for quick core change of the utility model, a card slot is opened on the inner wall of the mold, and a second telescopic rod is provided on the inner wall of the card slot. The top of the second telescopic rod is connected with a stop block, and the surface of the stop block is connected with a circular plate, and the inner wall of the circular plate is provided with a connecting plate, and a connecting block is provided at the center of the side end of the circular plate, and the surface of the connecting block is internally connected with a connecting rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1) When the mold core inside the mold is replaced more quickly, the telescopic shaft connected to the power supply is started, so that the telescopic shaft drives the fixed plate and the clamping plate to be removed from the surface of the mold, and then the first telescopic rod connected to the power supply is started, so that the first telescopic rod drives the clamping plate and the arc plate to move forward, so that the restriction on the surface of the mold core is removed, and the mold core inside the mold can be quickly replaced, making the method of replacing the mold core more convenient;

[0016] 2) When it is necessary to limit the position of the core rod, the position of the core rod is limited under the action of the circular plate and the connecting plate. At the same time, the connecting rod at the end of the circular plate makes the connection between the two sets of circular plates more stable, so that when the core is replaced, the position of the core rod is limited, and when the core is replaced, the stability of the mold is improved.
