Description

A sliding block device with simultaneous molding on both sides

technical field

The utility model relates to a sliding block device with two sides formed simultaneously.

Background technique

Mold (mú jù), various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry".

Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

Existing mold molding has the following defects:

1. Both sides of the product have negative angles and are molded at the same time, and the spacing is small. After the ordinary slider is formed, it cannot be demoulded, and additional processes are required, resulting in a substantial increase in mold and labor costs and a decrease in production efficiency.

2. The forming distance of the part is small, and the ordinary inclined slider cannot be realized, and the stroke is not enough to demould, so it is necessary to increase the mold.

Utility model content

The technical problem to be solved by the utility model is to provide a slider device that saves labor cost, can form both sides at the same time, and can facilitate stripping.

In order to solve the above problems, the utility model adopts the following technical solutions:

A slider device with simultaneous molding on both sides, comprising an upper mold and a lower mold, the upper mold is directly above the lower mold, a slider is provided on the upper mold, and first springs are connected to both sides of the slider, so There is a crack in the middle of the slider, an incision is provided under the crack, a lower pressing material is provided on the lower mold, forming holes are provided on both sides of the lower pressing material, and a slotting knife is provided in the middle of the lower pressing material. , the bottom of the pressing material is connected with a second spring, a product is arranged above the pressing material, and the inserting knife is facing the incision.

Preferably, a gap is provided between the slider and the first spring.

Preferably, the size of the gap is consistent with the width of the insertion knife.

Preferably, there are two second springs.

Preferably, the insertion knife is fixed.

Preferably, the forming mechanism is fixed.

The beneficial effects of the utility model are: through the set forming male, the product can be shaped after the inserting knife is inserted into the crack of the slider, and after forming, the forming male can be separated from the product by cooperating with the second spring, and at the same time, with the insertion When the knife comes out, the first spring generates elastic force to retract the slider, so that the product is separated from the slider, and finally the film release effect is achieved.

detailed description

In order to have a further understanding and understanding of the structural features and the achieved effects of the utility model, a detailed description is provided in conjunction with preferred embodiments and accompanying drawings, as follows:

As shown in Figure 1-2, a slider device with simultaneous molding on both sides, including an upper mold 1 and a lower mold 2, the upper mold 1 is directly above the lower mold 2, and the upper mold 1 is provided with a slider 3 , the first spring 4 is connected to both sides of the slider 3, a crack 5 is provided in the middle of the slider 3, an incision 6 is provided below the crack 5, and a lower pressing material 7 is provided on the lower mold 2, The two sides of the pressing material 7 are provided with forming pins 8, the middle part of the pressing material 7 is provided with a slotting knife 9, the bottom of the pressing material 7 is connected with a second spring 10, and the upper part of the pressing material 7 is provided with Product 11, the insertion knife 9 is facing the incision 6.

A gap 12 is provided between the slider 3 and the first spring 4 .

The size of the gap 12 is consistent with the width of the insertion knife 9, and the proofreading effect is better.

The second spring 10 is provided with two, and the balance is better.

Described inserting knife 9 is fixed setting, also can adjust according to the situation.

Described forming male 8 is fixed setting, also can adjust according to the situation.

work process:

The upper die 1 moves downward under the action of the downward force of the punch, driving the slider 3 to move downward. When the slider 3 touches the insert knife 9, the slide block 3 moves parallel to both sides under the action of the slope of the insert knife 9 , the first spring 4 is compressed, when the inserting knife 9 straightly enters the slider 3, the slider 3 stops moving to both sides and continues downward, the slider 3 and the lower pressing material 7 press the product 11, continue downward, and the second The spring 10 is compressed, and the slider 3 and the forming male 8 complete the molding; when the mold is opened, the upper mold 1 moves upward under the action of the upward force of the punch, and the product 11 moves upward under the elastic force of the lower pressing material 7 and the second spring 10, and the product 11 After detaching from the forming male 8, the upper mold 1 continues to drive the slider 3 to move upward. When the slider 3 moves to the top of the insertion knife 9, the slider 3 closes to the middle under the elastic force of the first spring 4. When it continues upward, the product 11 breaks away from slide block 3, and product 11 completes stripping.

The beneficial effects of the utility model are: through the set forming male, the product can be shaped after the inserting knife is inserted into the crack of the slider, and after forming, the forming male can be separated from the product by cooperating with the second spring, and at the same time, with the insertion When the knife comes out, the first spring generates elastic force to retract the slider, so that the product is separated from the slider, and finally the film release effect is achieved.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model .
