Abstract
The utility model discloses a novel demoulding structure, which comprises a mould core and a large loose core, wherein the upper part of the large loose core is in sliding fit with a positioning hole on the mould core, the lower part of the large loose core is provided with an I-shaped part, and one section below the I-shaped part is an inclined section and forms an included angle of 4-6 degrees with the horizontal plane; a sliding seat is arranged beside the large loose core, the left part of the sliding seat is provided with a sliding groove, and the sliding groove is in sliding fit with the I-shaped part; the right part of the sliding seat is fixedly connected with the left part of a connecting rod which is horizontally arranged, and a T-shaped groove connected with a lateral oil cylinder is formed in the right end part of the connecting rod. Connecting rod and sliding seat in the present case are whole removal together under the drive of side direction hydro-cylinder to the slope section through I shape portion realizes loosing core greatly reciprocating, so that take out loose core greatly, release the package power of cover die side, and then product stays in the cover die side when effectively preventing the drawing of patterns.
Description
Technical Field
The utility model belongs to the die-casting field especially relates to a novel demoulding structure.
Background
The existing large loose core is fixed together with a mold core and cannot move, so that the wrapping force of the fixed mold side is too large, and a product is easily left on the fixed mold side during demolding.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel demoulding structure is provided, the too big problem of prior art packing power is intended to overcome.
The technical scheme of the utility model as follows: the utility model provides a novel demoulding structure, includes the mold core and looses core greatly, its characterized in that: the upper part of the large core pulling is in sliding fit with the positioning hole on the mold core, the lower part of the large core pulling is provided with an I-shaped part, and one section below the I-shaped part is an inclined section and forms an included angle of 4-6 degrees with the horizontal plane; a sliding seat is arranged beside the large loose core, a sliding groove is formed in the left part of the sliding seat, and the sliding groove is in sliding fit with the I-shaped part; the right part of the sliding seat is fixedly connected with the left part of a connecting rod which is horizontally arranged, and a T-shaped groove connected with a lateral oil cylinder is formed in the right end part of the connecting rod.
When the lateral oil cylinder acts, the connecting rod and the sliding seat are driven to integrally move together, and the large core pulling is realized through the inclined section of the I-shaped part to move up and down, so that the large core pulling is pulled out, the tightening force of the fixed mold side is released, and the product is effectively prevented from being left on the fixed mold side during demolding.
In order to cool the die, the inner cavity of the large core pulling is a water cooling cavity, a water inlet hole and a water outlet hole are formed in the vertical section of the I-shaped portion, and the two holes are communicated with the water cooling cavity.
Preferably, an included angle of 5 degrees is formed between the lower section of the I-shaped part and the horizontal plane.
Has the advantages that: connecting rod and sliding seat in the present case are whole removal together under the drive of side direction hydro-cylinder to the slope section through I shape portion realizes loosing core greatly reciprocating, so that take out loose core greatly, release the package power of cover die side, and then product stays in the cover die side when effectively preventing the drawing of patterns.
Drawings
Fig. 1 is the schematic structural diagram of the utility model with the mold core removed.
Fig. 2 is an installation schematic diagram of the large core back 2 in fig. 1.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 and 2, the novel demolding structure comprises a mold core 1 and a large core 2, wherein the upper part of the large core 2 is in sliding fit with a positioning hole in the mold core 1, an i-shaped part 2a is arranged at the lower part of the large core, and one section below the i-shaped part 2a is an inclined section. The inclined section is low at the left and high at the right, and forms an included angle of 4-6 degrees with the horizontal plane, and preferably 5 degrees or 5.5 degrees. The inner cavity of the large loose core 2 is a water cooling cavity, and a water inlet hole and a water outlet hole are formed in the vertical section of the I-shaped part 2a and are communicated with the water cooling cavity.
A sliding seat 3 is arranged beside the large loose core 2, a sliding groove 3a is formed in the left part of the sliding seat 3, and the sliding groove 3a is in sliding fit with the I-shaped part 2 a; the right part of the sliding seat 3 is fixedly connected with the left part of a connecting rod 4 which is horizontally arranged, and a T-shaped groove 4a connected with a lateral oil cylinder is formed in the right end part of the connecting rod 4. When the lateral oil cylinder acts, the connecting rod 4 and the sliding seat 3 are driven to integrally move left and right linearly, the large core pulling 2 is moved up and down through the inclined section of the I-shaped part 2a, the large core pulling 2 is pulled out, the tightening force on the fixed die side is released, and then the product is effectively prevented from being left on the fixed die side during demolding.
Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
