Description

Split type structure of mould inner wall lug

Technical Field

The utility model relates to a forming technology technical field especially relates to a split type structure of mould inner wall lug.

Background

When the product with the groove on the profile is poured and molded, a corresponding bump needs to be arranged inside the mold. In a general cam structure (see fig. 3), the movable cam 2 is an integral structure, the movable cam 2 is fixed on the mold through a pull rod 3, the pull rod 3 is in threaded connection with the movable cam 2, and after the molding is completed, the movable cam 2 can be removed from the mold together with the product after the pull rod 3 is removed. In the process, the drawing rods 3 penetrate through the mold wall 1, so that the air tightness of the mold is affected, and the mold can be released only after all the drawing rods 3 are separated from the movable lugs 2 during product demolding, so that the demolding efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the movable lug drawing of patterns is inconvenient and airtight unstable when pouring the shaping in the product that the medium-sized face of prior art has the recess, and the split type structure of mould inner wall lug that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a split type structure of mould inner wall lug, includes the unsmooth piece of components of a whole that can function independently, the unsmooth piece of components of a whole that can function independently includes the last concave block that separates with the mould and pre-buries in the inside lower convex block of mould wall, go up concave block and can dismantle with lower convex block and be connected, when the product carries out the drawing of patterns, go up concave block and can follow the product and deviate from together from the mould, lower convex block stays in the mould wall. The lower convex block is embedded in the die in advance, so that the air tightness of the die can be ensured.

Preferably, the upper concave block and the lower convex block are in sleeved connection through a convex block on the lower convex block, that is, the concave part of the upper concave block is sleeved on the convex block of the lower convex block, and the convex block of the lower convex block is used for positioning and limiting the upper concave block.

The utility model discloses in, when the unsmooth piece of components of a whole that can function independently is installed inside the mould, go up the bottom of concave piece and paste mutually with the inboard of mould wall, reduce the shaping liquid and get into between concave piece and the mould wall.

The split concave-convex block is not necessarily positioned at the straight bottom of the mold. Preferably, when the unsmooth piece of components of a whole that can function independently is located mould slope inner wall, the utility model provides an go up the concave piece and set up the drawing die angle down between the convex piece for go up the concave piece and break away from smoothly from convex piece down.

It is worth explaining, the utility model provides an go up the lug and can choose for use according to actual conditions, can accomplish go up the lug and deviate from the operation from the shaping product can.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the convex block in the split type structure of the convex block on the inner wall of the mold is split, when the product is demolded, the upper concave block can be detached from the mold along with the product, and after the product is demolded, the upper concave block is knocked out, so that the whole demolding process is fast and convenient, and the demolding efficiency is high.

2. The lower convex block of the convex block split type structure on the inner wall of the mold is pre-embedded in the mold, so that the air tightness of the mold can be ensured.

FIG. 2 is a schematic structural view of an embodiment 2 of a split-type structure of bumps on the inner wall of the mold;

fig. 3 is a schematic structural view of the movable protrusion on the inner wall of the mold in the prior art.

In the figure: 1. a mold wall; 2. a movable projection; 3. a pull rod; 4. a split concave-convex block; 41. a concave block is arranged; 42. and (7) a lower bump.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1, a split type structure of a convex block on the inner wall of a mold comprises a split type concave-convex block 4, wherein the split type concave-convex block 4 comprises an upper concave block 41 separated from the mold and a lower convex block 42 pre-embedded inside the mold wall 1, the upper concave block 41 is connected with the lower convex block 42 through a convex block on the lower convex block 42, and the convex block of the lower convex block 42 is used for positioning and limiting the upper concave block 41. The lower bump 42 is pre-embedded in the mold, so that the air tightness of the mold can be ensured.

When the product is to be demolded, the upper concave blocks 41 can be ejected from the mold along with the product, leaving the lower convex blocks 42 in the mold wall 1. The product demoulding is convenient, after the product demoulding, the upper concave block 41 is knocked out, meanwhile, a new upper concave block 41 can be installed in the mould, the forming processing is continued, and the production efficiency is improved.

In this embodiment, when the split concave-convex block 4 is installed inside the mold, the bottom of the concave-convex block 41 is attached to the inner side of the mold wall 1, so as to reduce the molding liquid from entering between the concave-convex block 41 and the mold wall 1.

In this embodiment, the split concave-convex block 4 is located at the straight bottom of the mold, the demolding angle of the upper concave block 41 is 2 degrees, and the upper concave block 41 can be conveniently knocked out of the molded product.

Example 2

Referring to fig. 2, the split type structure of the convex block on the inner wall of the mold comprises a split type concave-convex block 4, an upper concave block 41 separated from the mold by the split type concave-convex block 4, and a lower convex block 42 pre-embedded inside the mold wall 1, wherein the upper concave block 41 is connected with the lower convex block 42 through a convex block on the lower convex block 42, and the convex block of the lower convex block 42 is used for positioning and limiting the upper concave block 41. The lower bump 42 is pre-embedded in the mold, so that the air tightness of the mold can be ensured.

In this embodiment, when the split concave-convex block 4 is installed inside the mold, the bottom of the concave-convex block 41 is attached to the inner side of the mold wall 1, so that the molding liquid is prevented from entering between the concave-convex block 41 and the mold wall 1.

In this embodiment, the split concave-convex block 4 is located in the inclined interior of the mold, and a draft angle is provided between the upper concave block 41 and the lower concave block 42 for the smooth separation of the upper concave block 41 from the lower concave block 42.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
