Description

Technical Field

[0001] The present invention relates to the technical field of mold mechanisms, and in particular to a slider mechanism inside a mold.

Background Art

[0002] As Figure 1 shown in the product 50, the first structure 20 and the second structure 30 on both sides of this product 50 are straight surfaces. If the direct mold opening method of male and female molds is used during production and molding, the product 50 will be damaged due to the draft angle during mold opening.

[0003] Currently, the method of adding sliders to the mold is used to mold this product 50. As Figure 2 shown in the mold core structure for currently molding this product 50, a set of slider mechanisms need to be provided on both sides of each product 50 respectively, that is, slider inserts 40 for forming the structure of the product 50 and slider bodies for driving the sliding inserts 40 to withdraw from the structure of the product 50 need to be provided. Then, eight slider inserts 40 and their matching slider bodies need to be provided in a general four-cavity mold. However, this makes the required mold volume large and leads to a high production cost of the product 50.

[0004] In view of this, it is necessary to provide a slider mechanism inside a mold to solve the above problems.

Summary of the Invention

[0005] The technical problem to be solved by the present invention is that for a product with straight surface structures on both sides, currently, the method of adding sliders to the mold is used to mold this product. A set of slider mechanisms need to be provided at the structures on both sides of the product respectively. Then, eight slider inserts and their matching slider bodies need to be provided in a general four-cavity mold. This makes the required mold volume large and leads to a high production cost of the product. Therefore, the present invention provides a slider mechanism inside a mold to solve the above problems.

[0006] The solution of the present invention to solve its technical problem is: a slider mechanism inside a mold, including:

[0007] A female mold, in which a slider bundle block and a cam pin are provided; wherein,

[0008] The slider bundle block is fixed inside the female mold through a fixing member. A first inclined surface is provided on one side of the slider bundle block. The first inclined surface is used to push the second inclined surface of the first slider body during mold closing, so that the first slider body drives the first slider insert to move towards the first structure end of the molded product. A first inclined slot is provided at one end of the slider bundle block. The first inclined slot is used to insert into the second inclined slot in the first slider body during mold closing, and can cooperate with the first inclined surface to make the first slider body drive the first slider insert to move towards the first structure end of the molded product. During mold opening, the first inclined slot can cooperate with an elastic member to make the first slider body drive the first slider insert to withdraw from the first structure of the product;

[0009] The inclined guide pillar is fixed in the female mold through a fixing member. During mold closing, the inclined guide pillar can be inserted into the round hole of the second slider body, so that the second slider body drives the second slider insert to move towards the second structural end of the molded product. During mold opening, the inclined guide pillar can be withdrawn from the round hole of the second slider body, so that the second slider body drives the second slider insert to withdraw from the second structure of the product;

[0010] The male mold cooperates with the female mold to form a product. The male mold is provided with a first slider mechanism and a second slider mechanism; among them,

[0011] The first slider mechanism is used to form the first structure of the product. The first slider mechanism includes: a first slider body, a first slider insert, and a first slider pressing plate; among them,

During mold opening, the elastic member can drive the first slider insert to withdraw from the first structure of the product through the elastic force. The first slider body is provided with a second inclined groove, which can cooperate with the first inclined groove of the slider bundle block. During mold closing, it can cooperate with the first inclined surface of the slider bundle block and the second inclined surface of the first slider body to drive the first slider insert fixed thereon to move to the position of the first structure of the molded product. During mold opening, it can cooperate with the elastic member to drive the first slider insert to withdraw from the position of the first structure of the product. One side of the first slider body is provided with a first concave platform, which can cooperate with the first slider pressing plate to limit the displacement of the first slider body;

[0013] One end of the first slider insert is shaped to conform to the first structure of the product and is used to form the first structure of the product. The other end of the first slider insert is fixed to one end of the first slider body through a fixing member. During mold closing, the first slider insert can be driven by the first slider body to move to the position of the first structure of the molded product. During mold opening, the first slider insert can be driven by the first slider body to withdraw from the first structure of the product;

[0014] The first slider pressing plate is fixed in the male mold through a fixing member. The first slider pressing plate is arranged on the first concave platform of the first slider body to limit the displacement of the first slider body;

[0015] The second slider mechanism is used to form the second structure of the product. The second slider mechanism includes: a second slider body, a second slider insert, and a second slider pressure plate. Among them,

[0016] The second slider body is movably arranged in the male mold. The second slider body is provided with a round hole. When the mold is closed, the round hole can drive the second slider body with the second slider insert fixed thereon to move to the position of the second structure of the formed product under the action of the angled guide pillar. When the mold is opened, the round hole can drive the second slider body with the second slider insert fixed thereon to withdraw from the position of the second structure of the product under the action of the angled guide pillar. One side of the second slider body is provided with a second concave platform, and the second concave platform can cooperate with the second slider pressure plate to limit the displacement of the second slider body through the second slider pressure plate.

[0017] The second slider insert has one end conforming to the second structure of the product and is used to form the second structure of the product. The other end of the second slider insert is fixed to one end of the second slider body through a fixing member. When the mold is closed, the second slider insert can be driven by the second slider body to move to the position of the second structure of the formed product. When the mold is opened, the second slider insert can be driven by the second slider body to withdraw from the position of the second structure of the product.

[0018] The second slider pressure plate is fixed in the male mold through a fixing member. The second slider pressure plate is arranged on the second concave platform of the second slider body and is used to limit the displacement of the second slider body.

[0019] Preferably, the fixing members are all screws.

[0020] Preferably, the elastic member can be a spring.

[0021] Preferably, one end of the first slider body can be provided with a "T"-shaped groove, which can cooperate with the "T"-shaped groove of the first slider insert. After the two are fixedly connected through a fixing member, when the first slider body moves, the first slider insert can be driven to move together.

[0022] The beneficial effect of the present invention is that through a slider mechanism in the mold, the first slider mechanism and the second slider mechanism are used to form the first structure and the second structure of the product. Thus, only two sets of first slider mechanisms and two sets of second slider mechanisms need to be set in a general four-cavity mold, which can reduce the volume of the mold, and its processing is simple and convenient for installation.
