[0001] The utility model relates to the field related to industrial production, in particular to an inclined top seat for mold production. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed.

[0003] In the installation process of the inclined lift seat used in the existing mold, bolts are generally used to install the inclined lift seat on the top surface of the base plate, and the bolts are installed from the bottom to the top. This connection method has the problem that the bolts are easy to loosen, resulting in failure of the inclined lift mechanism, which seriously affects the life of the mold. The response strategy adopted for the loosening of the bolts is usually to use spring washers to prevent loosening. However, in actual use, the elastic force provided by the spring washers has a small pre-tightening torque on the bolts, which makes the anti-loosening effect of the bolts general. The bolts are still easy to loosen, which is not conducive to the use of the inclined lift mechanism. Utility Model Content

By relying on the horizontal connection of the connecting frame, the first bolt and the base, and coordinating the vertical connection of the bolt and the base, the base is fixed in the longitudinal and transverse directions, and the influence caused by the loosening of the vertical bolts is reduced, thereby improving the stability of the base installed on the bottom plate.

[0026] See also Figure 2-5The utility model provides an inclined top seat for mold production. The bottom end of the fixing device 6 is fixed to the bottom plate 1. The fixing device 6 includes a connecting seat 61, a fixed square steel 62, a connecting frame 63, a first bolt 64, a second bolt 65, and a clamping piece 66. The connecting seat 61 is welded and fixed to the top of the bottom plate 1. The fixed square steel 62 is locked and fixed with the connecting seat 61 by the second bolt 65. The inner sides of the fixed square steel 62 and the connecting seat 61 are respectively connected to the base 4. The connecting frame 63 is embedded in the fixed square steel 62 to the left. The connecting frame 63 is locked and fixed with the fixed square steel 62 by the first bolt 64. The top of the clamping piece 66 is fixed to the fixed square steel 62.

[0027] In this embodiment, a rectangular groove and a circular groove are respectively provided inside the connection seat 61, and a thread is provided in the circular groove for threaded connection with the second bolt 65, and the rectangular groove is used for embedding the clamping member 66, and after the clamping member 66 is embedded, there is still a gap at the left and right ends of the rectangular groove, which is used to form a clamping shape with the groove after the clamping member 66 is unfolded, thereby strengthening the connection strength between the connection seat 61 and the fixed square steel 62. The clamping structure effectively avoids the unstable connection caused by a slight loosening of the second bolt 65. The middle parts of the connection seat 61 and the fixed square steel 62 are both provided with rectangular through holes, and the cross-section of the connection seat 61 is The surface is "concave", and the cross-section of the fixed square steel 62 is "convex", which is convenient for the connection of the base 4, and the fixed square steel 62 is embedded downward in the middle of the connecting seat 61, which serves the purpose of fitting connection. Two sets of plug plates are provided at the left end of the connecting frame 63, and the connecting frame is embedded inwardly with the fixed square steel 62 and the base 4, and cooperates with the connection between the bolts 3 and the base 4, so that the installation of the base 4 forms a cross lock, which strengthens the connection strength of the base 4 installed on the bottom plate 1, and effectively avoids the unstable installation of the base 4 caused by the loosening of the bolts in a certain direction, which affects the movement of the inclined push rod 5. The connecting frame 63 is made of stainless steel, which is strong, corrosion-resistant, and not easy to deform.

[0028] See also Figure 6 The utility model provides an inclined top seat for mold production. The clamping part 66 includes an assembly 661, a positioning rod 662, a spring 663, and a clamping block 664. The top of the assembly 661 is fixed to the fixed square steel 62, and the positioning rod 662 is installed inside it. The right end of the spring 663 is fixed to the assembly 661, and the right end of the clamping block 664 is elastically connected to the spring 663 by the spring 663.

[0029] In this embodiment, the inner side of the clamping block 664 is provided with a chamfer, so that when the second bolt 65 is threadedly rotated downward, the clamping block 664 is pushed outward to squeeze the spring 663, so that the clamping block 664 enters the interior of the connecting seat 61 to both sides, thereby strengthening the connection strength between the two. The clamping block 664 is provided with multiple groups, and each two groups of clamping blocks 664 are symmetrically distributed on the left and right. Each two groups of symmetrical clamping blocks 664 move in opposite directions to form a clamping structure with the connecting seat 61 to strengthen the connection. The spring 663 is made of alloy spring steel and has high tensile strength, elastic limit, and high fatigue strength. After the second bolt 65 connects the connecting seat 61 and the fixed square steel 62, when the second bolt 65 is slightly loosened and moves upward, because the clamping block 664 is present above the interior of the connecting seat 61, the slight upward loosening of the second bolt 65 does not affect the degree of clamping between the clamping block 664 and the connecting seat 61. Due to the existence of the clamping structure, the connection between the connecting seat 61 and the fixed square steel 62 will not be loosened, and a stable connection can still be maintained.

[0030] See also Figure 1-Figure 6 When in use, the fixed square steel 62 is embedded in the interior of the connecting seat 61 and is locked and fixed by the second bolt 65. When the second bolt 65 continues to move downward, the clamping block 664 is pushed to squeeze the spring 663 and move outward, so that the clamping block 664 and the connecting seat 61 form a clamping structure. The clamping structure is used to strengthen the connection between the connecting seat 61 and the fixed square steel 62. When the second bolt 65 is slightly loosened, the influence on the clamping block 664 is negligible, and the clamping block 664 still maintains the clamping connection with the connecting seat 61, so as to achieve a stable connection between the connecting seat 61 and the fixed square steel 62. Then;

[0031] The base 4 is embedded in the connecting seat 61 and the fixed square steel 62, and then the spring washer 2 is pressed against the bottom plate 1, and the bolt 3 is passed through the spring washer 2 to lock and fix the base 4 upward, and the base 4 is fixed in the vertical direction. The connecting frame 63 is embedded in the fixed square steel 62 and the base 4, and the first bolt 64 is used to lock it, so as to achieve the horizontal and vertical fixation of the base 4, and stably fix the base 4 on the bottom plate 1;

[0032] The bottom plate 1 moves upward under the control of the injection molding machine, driving the base 4 upward synchronously, and the inclined ejector rod 5 slides inside the base 4 under the force, lifting the mold and leaving the mold, so as to facilitate the removal of the mold.
