Abstract

The utility model relates to a time delay controller for a sliding block, which comprises a fixed block, wherein a limit block is mounted on the fixed block, and can slide in the fixed block; a spring is arranged at the upper end of the limit block; the lower end of the limit block is matched with a sliding block limit slot in shape; the length of the limit block is larger than that of the fixed block. The sliding block time delay controller can realize the time delay control of a large sliding block.

Description

A kind of slide block delay controller

Technical field

The utility model relates to technical field of mold, particularly relates to a kind of slide block delay controller.

Background technology

Slide block is a kind of common side core drawing structure in injection mold, the general mode of Angle Pin that adopts utilizes the strength of mould die sinking to transfer to slide block to realize side core-pulling, this kind of mode is that mould die sinking and slide block move simultaneously, but mould one segment distance inner slide when die sinking is failure to actuate sometimes, waits other parts to exit and get out of the way just motion behind space.

Existing time-delay structure is generally to draw out emptiness avoiding hole at the exit axis of sliding block inclined guide pillar, in die sinking one segment distance, dial less than slide block, after reaching certain distance, stir slide block, realize time delay, it is motionless that this process will guarantee that slide block remains on original position, existing control device is for dialling pearl in location, but the load of this structure maximum is 100KG, can be inapplicable when slide block quality surpasses 100KG.Another time-delay structure is to adopt driving lever to realize time delay, just on slide block, design beveled aperture, but this kind of structure need to strengthen slide block size, and processing is trouble, and cost is higher.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of slide block delay controller, can realize the time delay of large-scale slide block and control.

The utility model solves the technical scheme that its technical problem adopts: a kind of slide block delay controller is provided, comprises fixed block, on described fixed block, limited block is installed, described limited block can slide in described fixed block; Described limited block upper end is provided with spring, and the shape of lower end is mated mutually with the shape of slide block stopper slot; The length of described limited block is greater than the length of described fixed block.

Described fixed block is arranged in mother module core; Described spring upper end is fixed on mother module core.

Described limited block lower end is provided with rolls pin.

Beneficial effect

Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model utilizes limited block that slide block is blocked, in a segment distance of die sinking, limiting slide block slides, matched moulds process in utilize spring that limited block is snapped in to the stopper slot on slide block, thereby realize slide block time delay, exit, this kind of structure can be born larger load, successfully solved the problem that large-scale slide block time delay is exited.The utility model is simple in structure in addition, and processing and installation are more for convenience.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is die sinking schematic diagram of the present utility model;

Fig. 3 is matched moulds schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment of the present utility model relates to a kind of slide block delay controller, as shown in Figure 1, comprises fixed block 1, on described fixed block 1, limited block 2 is installed, and described limited block 2 can be in the interior slip of described fixed block 1; Described limited block 2 upper ends are provided with spring 3, and the shape of lower end is mated mutually with the shape of slide block 6 stopper slots; The length of described limited block 2 is greater than the length of described fixed block 1.Described limited block 2 lower ends are also provided with rolls pin 4, can directly and between limited block 2 slide by anti-limited slip block 6.Described fixed block 1 is arranged in mother module core 5, and described spring 3 upper ends are fixed on mother module core 5.

Mould, when just die sinking, as shown in Figure 1, because limited block 2 blocks slide block 6, is fixed slide block 6; When mould die sinking distance surpasses after stroke-limit, limited block 2 leaves slide block 6, slide block 6 setting in motions, and as shown in Figure 2, die sinking is spacing stroke (distance of time delay, revises die sinking apart from the value of S as required) apart from S.When matched moulds, roll pin 4 and first touch slide block 6, while continuing matched moulds, pin is rolled in compression, makes spring 3 start compression, roll pin 4 and slide in shoe surface, as shown in Figure 3, until matched moulds completes, effect lower position block 2 at spring 3 snaps in the stopper slot on slide block 6, gets back to state as shown in Figure 1.

Be not difficult to find, the utility model utilizes limited block that slide block is blocked, in a segment distance of die sinking, limiting slide block slides, matched moulds process in utilize spring that limited block is snapped in to the stopper slot on slide block, thereby realizing slide block time delay exits, this kind of structure can be born larger load, successfully solved the problem that large-scale slide block time delay is exited.The utility model is simple in structure in addition, and processing and installation are more for convenience.
