Background

The dumbbell of general mass production directly uses automatic molding machine to make the sand mould when casting, and small batch custom-made's ganged dumbbell generally uses wood pattern or 3D to print the mode preparation sand mould, but wood pattern and 3D model can only produce a barbell generally once, can't directly form a plurality of die cavities and runner in the sand mould like the metal mould of automatic molding machine, leads to the number of times of small batch foundry goods preparation sand mould to be many, and production efficiency is lower.

Disclosure of Invention

In order to solve the problems, the utility model provides a 3D printing casting sand box which is formed by forming a plurality of cavities in one sand box and forming runners in the cavities, and can be reused by a wood mold and a 3D model.

The utility model provides a casting sand box is printed to 3D, includes case, lower case, locating plate and at least a set of 3D printing model, its characterized in that: the utility model discloses a three-dimensional printing device for the plastic film, including the locating plate, the locating plate is equipped with the locating plate, the opposite side is equipped with the locating plate, be equipped with runner shaping arch between the locating plate, the 3D prints the model including last mould and lower mould, one side of going up the mould is equipped with the reference column, one side of lower mould is equipped with the reference column down, it is equipped with the runner groove on the mould to go up.

Further, both sides of the upper box are provided with upper positioning jacks, and both sides of the lower box are provided with lower positioning jacks.

Further, the number of the upper die positioning holes is 2, and the number of the lower die positioning holes is 1.

The utility model has the beneficial effects that:

1. positioning the multiple molds in the sand box by utilizing the plugging positioning of the positioning plate and the molds so as to facilitate the positioning of the multiple molds in the sand box and form multiple cavities in the multiple sand molds;

2. the model and the positioning plate can be reused, so that the cost is greatly saved;

3. and the locating plate and the runner are manufactured by using a wood die, and the model is processed by using a 3D printing method, so that the processing efficiency is improved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1-2, the present utility model provides a 3D printing casting flask, comprising an upper flask 1, a lower flask 2, a positioning plate 3, and at least one set of 3D printing models 4, characterized in that: the material of locating plate 3 is pine, and there is last mould locating hole 301 locating plate 3 one side, and there is lower mould locating hole 302 locating plate 3 the opposite side, has runner shaping arch 303,3D to print model 4 including last mould 401 and lower mould 402 between the lower mould locating hole 302, and there is last reference column 403 on one side of last mould 401, and there is lower reference column 404 on one side of lower mould 402, and the shape size of reference column is the same on the model, has runner groove 405 on the last mould 401, and the both ends of runner groove 405 meet with lower reference column 404 of lower mould 402 respectively.

Further, the upper case 1 has upper positioning insertion holes 101 on both sides, and the lower case 2 has lower positioning insertion holes 102 on both sides.

Further, the number of the upper die positioning holes 301 is 2, and the number of the lower die positioning holes 302 is 1.

When the barbell molding machine is specifically used, firstly, the upper die 401 of the 3D printing model 4 is installed on the upper die positioning hole 301 of the positioning plate 3, the positioning plate 3 is placed below the upper box 1, casting sand is filled into the upper box 1, then the positioning plate 3 and the upper die 401 are taken down, pouring gates and air holes are manufactured on the upper die, the other surface of the positioning plate 3 is used, the 3D printing model 4 is installed on the lower die positioning hole 302 of the positioning plate 3, the positioning plate 3 and the lower box 2 are combined, casting sand is filled, molding of a lower cavity and a runner is completed, the positioning plate 3 and the lower die 402 are taken down, and finally, two sand boxes are combined and cast, so that the barbell molding of a group of barbells can be completed.
